as seen in fig1 an existing cigarette vending machine 9 basically includes a mechanical coin totalizer unit and mechanical cigarette pack dispensing mechanism for the dispensing of cigarettes therefrom . the existing cigarette vending machine 9 , which will be modified by the present invention , could be any one of a number of models such as those sold by national vendors , inc . the basic cigarette vending machine 9 , prior to the modification would typically include a viewing window 11 , through which a potential purchaser can determine which packs 13 of cigarettes are available . the purchaser would deposit a proper amount of coin currency in the form of nickels , dimes and / or quarters in the coin slot 15 . such machines 9 can be configured to offer packs of cigarettes which are to be purchased for different prices . after the proper amount of coin currency has been deposited in the slot 15 , the purchaser could select the pack 13 of cigarettes corresponding to the amount of money deposited by simply pulling the appropriate selection knob 17 . the selected pack 13 of cigarettes would be dispensed to a tray 19 physically below the selection knob area . as will be seen , if the purchaser deposited the maximum amount of coin currency required for the most expensive pack 13 of cigarettes , any one of the selection knobs 17 could be pulled for the dispensing of any pack 13 of cigarettes including those costing less than the more expensive packs 13 . an additional feature of interest in the existing cigarette vending machine 9 includes the capability of the purchaser to change his mind regarding the purchase of a pack 13 of cigarettes . after coin currency has been deposited in the slot 15 , if no selection knob 17 has been pulled , the purchaser can pull down a coin rejection lever 21 to cause all of the coins to be ejected to the tray 19 for recollection by the purchaser . as will be seen , the present invention requires significant modification of the mechanical totalizer unit within the cigarette vending machine 9 and , after the preferred embodiment of the present invention is installed , the machine 9 will generally operate in a different manner . for example , with the preferred embodiment of the present invention , the owner - operator of the machine 10 would only offer packs 13 of cigarettes for one particular price . additionally , there would be an indication on the machine 9 that only quarters should be deposited in the coin currency slot 15 . if the wrong coin currency or a slug is deposited therein , the coin accepter and slug ejector would be employed to insure that only quarters are accepted . the coin rejection lever 21 would be used to remove jams or other slugs in the same manner as before . however , the instructions on the machine 9 would make it clear to a potential purchaser that the coin rejection lever 21 could not be used to return all currency deposited therein simply because the purchaser determined not to make a selection . there is included no means in the preferred embodiment of the present invention for the return of any proper coin and / or paper currency which has been deposited and accepted for the eventual selection of a pack 13 of cigarettes . the preferred embodiment of the present invention primarily includes , in addition to the modifications within the existing machine 9 , an added box 25 as seen in fig2 . the box 25 is preferably installed on the side of the machine 9 in the region indicated by the dotted line 27 in fig1 . the box 25 includes a wire harness 29 extending therefrom for insertion into the machine 9 through a hole 31 in the side wall of the machine 9 provided for this purpose . the preferred box 25 , as will be seen , includes a paper currency receiving opening 33 on the front face thereof . an electronic currency display 35 indicates the amount of coin and / or paper currency which has been deposited in the paper currency slot 33 and / or the coin slot 15 toward the purchase of a pack 13 of cigarettes . more significantly , the box 25 will be seen to include a currency totalizer control means 37 in the form of a specifically designed printed circuit board for performing the operation and control functions which will be discussed hereinbelow . the preferred printed circuit board includes the electronic currency display 35 , in the form of a led or the like , mounted thereon and is installed in the box 25 so that the display 35 can be clearly seen on the front of the box 25 by a purchaser . as shown schematically in fig3 the preferred embodiment of the invention includes the improved paper and coin currency totalizer 41 including components which are physically provided in the box 25 and in the vending machine 9 . the box 25 primarily includes the currency totalizer control means 37 , which is preferably in the form of the specifically designed printed circuit board having the display 35 thereon . such printed circuit boards are well known in the vending machine art and are within the design capability of those skilled in the vending machine art when it is determined which functions are to be performed and which specific components , available through other means , are to be utilized . the preferred printed circuit board would include selection switches ( not shown ) to provide a variable selection means for selectively varying the predetermined amount of currency needed to allow the selection of a pack of cigarettes . in the preferred currency totalizer control means 37 , the predetermined amount of currency can be selectively varied by the selection switches , at quarter increments , ranging from $ 0 . 25 to $ 7 . 75 . also housed within the box 25 is one of numerous types of paper currency verification and sensing means 39 which are readily available and well - known in the vending machine field . the preferred paper currency verification and sensing means 39 may be , for example , of the type sold by mars electronics of west chester , pa ., under the model no . vfm1 . the preferred paper and coin currency totalizer system 41 also includes components which are installed within the machine 9 . the components installed within the machine 9 will be seen to provide the desired functions and operations while utilizing some of the mechanical components in the existing machine 9 and the mechanical totalizer unit and mechanical dispensing mechanism thereof . the components of the paper and coin currency totalizer system 41 within the machine 9 include a coin currency sensor 115 , actuation means 119 and a reset sensor 129 , which are best seen in fig6 and discussed in detail hereinbelow . the coin currency sensor 115 would preferably be an optic device of the type sold under the model no . opb800w55 by optek technology , inc . of carrollton , tex . the actuation means 119 will be capable of allowing the purchaser to pull an appropriate selection knob 17 for the dispensing of a pack 13 of cigarettes after a proper amount of currency has been deposited . in other words , the actuation means 119 does not actually perform any direct function for the dispensing of a pack 13 of cigarettes but simply allows the purchaser to pull a desired selection knob 17 for the dispensing of a pack 13 of cigarettes with the existing mechanical dispensing mechanism in the machine 9 . the reset sensor 129 includes means , also within the machine 9 , for sensing the mechanical dispensing of the pack 13 in order to indicate when the selection has been made . the reset sensor 129 provides a signal to the currency totalizer control means 37 for resetting the entire paper and coin currency totalizer system 41 to indicate that a selection has been made and additional currency must be deposited in either the coin slot 15 or the paper slot 33 prior to the disposition of another pack 13 of cigarettes . as seen in fig4 an existing mechanical totalizer unit 10 within such machines 9 has been extensively sold by national vendors , inc ., and has been successfully utilized throughout the cigarette vending machine field in the past . the mechanical totalizer unit 10 includes numerous components and features as disclosed in detail in u . s . pat . nos . 2 , 993 , 581 and 3 , 028 , 940 . while most of the mechanical components which are provided in the preferred mechanical dispensing mechanisms for the cigarette vending machines 9 are not shown in fig1 as will be seen , the function and operation of the components which directly relate to the operation of the mechanical totalizer unit 10 will be discussed hereinbelow . as shown in fig4 the cover plate of the mechanical totalizer unit 10 has been removed to reveal the interior of the unit 10 as it would be seen from the right side of the cigarette vending machine 9 . in other words , after coin currency has been deposited in the coin slot 15 , it would pass through a coin selector and slug rejecter device ( not shown ) which would be physically above the mechanical totalizer unit 10 . each accepted coin would be directed to one of three coin chutes ( not shown ) in a coin chute assembly 12 . in order to determine if a proper amount of coin currency has been deposited in the coin chute assembly 12 , a mechanical coin recorder mechanism 14 is mounted in the totalizer unit 10 and includes a trip wire 16 . the extended finger 18 of the trip wire 16 extends through an arcuate slot 20 which intersects each of the chutes of the coin chute assembly 12 . as discussed above , when a nickel passes through the nickel chute , the extended finger 18 is deflected along the arcuate slot 20 to produce a predetermined movement of the trip wire 16 . a dime would move the trip wire 16 twice as far as that produced by a nickel and a quarter would produce movement of the trip wire 16 through an arcuate distance which is five times that produced by a nickel . movement of the trip wire 16 causes a ratchet wheel ( not shown ) in the mechanical coin recorder mechanism 14 to be advanced in order to mechanically add the amount of coin currency passing through the chutes . depending on the actual amount of currency selected to be deposited for each of the three different prices of cigarettes which are being offered in the cigarette vending machine 9 , each of three separate discs ( not shown ) within the coin recorder mechanism 14 will be advanced for possible alignment of the notches thereof with respective latch release bars 22 . although it may appear from fig4 that there is only one latch release bar 22 , the three latch release bars 22 are generally aligned to cause two of the bars 22 to be behind the one actually shown . each latch release bar 22 is mounted on a common pivot 45 and includes a first end 24 and a second end 26 . the first end 24 of each latch release bar 22 includes a connecting element 28 . the connecting element 28 for each of the latch release bars 22 extends respectively to one of three release latches 30 , 32 , 34 . each of the three release latches 30 , 32 , 34 of the totalizer unit 10 extends through the rear wall thereof to produce movement of the release means ( not shown ) of the vending machine 9 . movement of the release means ( not shown ) to the release position by downward movement of its respective release latch 30 , 32 , 34 allows any of the selection knobs 17 for a particular price of cigarettes to be pulled for the dispensing of the pack 13 by the mechanical dispensing mechanism . downward movement of the release latch 30 will produce movement of one of the release to the release position . similarly , downward movement of release latch 32 allows any of the selection knobs 17 of a different price of cigarettes to be pulled when its corresponding release means is moved to the release position . the third release latch 34 , upon being moved downwardly , produces similar movement of its corresponding release means to the release position . as thus described , although a proper amount of coin currency may have been deposited to produce movement of the ratchet wheel within the coin recorder mechanism 14 for advancement of the respective discs thereof , no movement of the latch release bars 22 will occur until one of selection knobs 17 has been pulled . in other words , although the second end 26 of any one of the latch release bars 22 may be properly aligned with the corresponding notch in its respective disc , the actual upward movement of the second end 26 toward the disc or downward movement of the first end 24 to produce movement of its respective release latch 30 , 32 , 34 and release means will not occur until there is an attempt by the purchaser to select the desired pack 13 of cigarettes through the pulling movement of the selection knob 17 . as discussed above , in order to insure continued reliable operation of the coin recorder mechanism 14 , any contact between the respective discs therein and the second ends 26 of the latch release bars 22 is not desired unless a selection is actually being made . when a proper amount of coin currency has been deposited in the cigarette vending machine 9 to produce the alignment of the notch in the disc in the coin recorder mechanism 14 for selecting a particular pack 13 of cigarettes , a purchaser would be in a position to select the desired pack 13 of cigarettes . although all of the internal components of the mechanical dispensing mechanism within the cigarette vending machine 9 are not shown , initial movement of any of the selection knobs 17 would cause rotation of an actuation shaft 40 of the mechanical dispensing mechanism which extends through the back wall of the mechanical totalizer unit 10 . an actuation cam 42 mounted on the end of the actuation shaft 40 basically provides two functions . as will be seen , one function produces movement of the latch release bars 22 , and thus possible movement of the release latches 30 , 32 , 34 themselves , while the other function is to reset the mechanical coin recorder mechanism 14 . as shown in fig4 the actuation shaft 40 and actuation cam 42 are in a inactive position without any purchaser having pulled one of the selection knobs 17 . upon pulling a selection knob 17 , the actuation shaft 40 and actuation cam 42 are rotated clockwise to produce rotational movement of a cam slot 44 and a cam surface 46 of the actuation cam 42 . the cam surface 46 is shaped to produce rotational movement of a release arm 50 mounted on a pivot 52 . to produce the rotational movement of the release arm 50 , one end thereof includes a release roller 58 which is in contact with the cam surface 46 . the release arm 50 has an opposite , extended end 54 which includes three springs 56 which are respectively connected to the first ends 24 of the latch release bars 22 . consequently , if there were downward movement of the extended end 54 , the springs 56 would cause the latch release bars 22 to be pulled downward by the respective springs 56 to rotate the latch release bars 22 about the common pivot 45 . the release arm 50 is biased by a spring 60 in the counter - clockwise direction to maintain the release roller 58 in contact with the cam surface 46 of the actuation cam 42 . the spring 60 tends to prevent any movement of the extended end 54 and springs 56 to produce downward movement of the first end 24 of the release latch bars 22 until positive movement is produced by the cam surface 46 . as the actuation shaft 40 and actuation cam 42 rotate in a clockwise direction , the movement of the cam surface 46 beneath the release roller 58 produces clockwise rotation of the release arm 50 about the pivot 52 . the increased force produced by the expansion of the springs 56 provides the desired rotational force on each of the release latch bars 22 . once initial movement of the selection knob 17 has resulted in a clockwise force being applied to the first ends 24 of the latch release bars 22 , the second ends 26 will , obviously , try to rotate in an upward direction toward the coin recorder mechanism 14 . however , if the proper amount of coin currency has not been deposited through the coin chute assembly 12 , the respective discs in the coin recorder mechanism 14 will not have been sufficiently advanced for the notch thereof to be aligned with the second end 26 . if the discs are not properly advanced , continued upward movement of the second end 26 of the selected latch release bar 22 will be prevented . as a result , the first end 24 of the latch release bar 22 could not move downward despite the biasing force applied to the first end 24 by the extended end 54 and spring 56 of the release arm 50 . consequently , if the second end 26 is not capable of movement into its corresponding notch , the respective release latch 30 , 32 or 34 will not move downward to cause its respective release means to be moved to the release position . on the other hand , if a proper amount of coin currency has been deposited through the coin chute assembly 12 for a pack 13 of cigarettes requiring the least amount of coin currency , the appropriate latch release bar 22 will be properly aligned with the notch in the disc in the coin recorder mechanism 14 . as a result , the latch release bar 22 may be rotated clockwise as the second end 26 extends into the notch . upon movement of the selected latch release bar 22 , the downward movement of the first end 24 and the connecting element 28 will cause its respective release latch 30 , 32 or 34 to be moved downward to move the corresponding release means to the release position . assuming the purchaser has selected a pack of cigarettes for that particular value , the continued movement of the selection knob 17 to physically dispense the selected pack 13 is possible when the release latch 30 , 32 , or 34 and thus the corresponding release means of the machine 9 , is in the release position . if the purchaser were to deposit more coin currency than required for the selected pack 13 of cigarettes at the minimum cost , each of the notches in the disc might be sufficiently advanced so that all of the three latch release bars 22 could be rotated . consequently , the purchaser would be capable , after having deposited a sufficient amount of coin currency for the most expensive pack 13 of cigarettes in the cigarette vending machine 9 , of pulling any of the selection knobs 17 to dispense any pack 13 of cigarettes therein because all three of the latch release bars 22 would be rotated in a clockwise direction to move all three release latches 30 , 32 , 34 to the release position . as a result , if the maximum amount of coin currency has been deposited in the cigarette vending machine 9 , and thus through the mechanical totalizer unit 10 , either the lower , middle or higher priced cigarettes could be selected for dispensing from the cigarette vending machine 9 . if a purchaser deposited a sufficient amount of coin currency for the most expensive pack 13 of cigarettes therein but inadvertently pulled a selection knob 17 on a lower cost pack 13 of cigarettes , the totalizer unit 10 would allow such a selection but would not return any of the additional coin currency deposited in the machine 9 . as thus described , it should be clear that the initial movement of any one of the selection knobs 17 will cause rotation of the actuation shaft 40 and actuation cam 42 . with proper movement in the clockwise direction , any one of the release latches 30 , 32 , 34 and corresponding release means may be moved to the release position to allow continued movement of the selected knob 17 if the proper amount of coin currency has been deposited in the mechanical totalizer unit 10 . assuming a proper amount of coin currency has been deposited in the coin chute assembly 12 and that the purchaser has selected a proper pack 13 of cigarettes for disposition from the machine 9 , the release of the selection knob 17 will cause the actuation shaft 40 and the actuation cam 42 to be rotated in the counter - clockwise direction to be returned to the position as shown in fig4 . throughout rotational movement of the actuation shaft 40 and actuation cam 42 , the rotation of the cam slot 44 has produced movement of a reset lever 62 . the reset lever 62 is mounted for rotation about a pivot 64 and includes a reset roller 66 which extends into the cam slot 44 . the initial movement of the actuation cam 42 in a clockwise direction causes the reset roller 66 in the cam slot 44 to pivot the reset lever 62 in a clockwise direction about the pivot 64 . the extended end 68 of the reset lever 62 is coupled to reset linkage 70 which extends toward the coin recorder mechanism 14 . when the reset linkage 70 is moved upward with the pulling of a selection knob 17 , it is configured , upon returning to the non - selected position , to cause a resetting of the coin recorder mechanism 14 to the &# 34 ; zero &# 34 ; position . with the ratchet wheel and discs therein returned to the &# 34 ; zero &# 34 ; position , the coin recorder mechanism 14 will be returned to a condition as if no coin currency had been deposited in the mechanical totalizer unit 10 . as the particular selection knob 17 is released by the purchaser , the rotation of the actuation cam 42 to the position shown in fig4 causes a resetting of the coin recorder mechanism 14 through the counter - clockwise rotation of the reset lever 62 and downward movement of the reset linkage 70 . as thus described , the operation of the totalizer unit 10 allows proper selection of a pack 13 of cigarettes by a purchaser after a proper amount of coin currency has been deposited in the coin slot 15 . however , the totalizer unit 10 includes another feature if the purchaser deposits coin currency in the cigarette vending machine 9 and then determines that no selection is desired . below the coin chute assembly 12 is a pair of doors 71 , 72 which are pivotally supported at a separating wall 73 and include extended ends which are respectively aligned with the lower walls 75 . the doors 71 , 72 combine to retain therebetween all of the coin currency deposited through the coin chute assembly 12 until one of two events occurs . if a purchaser determines that no selection should be made , the coin rejection lever 21 on the front of the cigarette vending machine 9 can be pulled downwardly to lower coin door 71 . as a result , coin currency collected between the doors 71 , 72 will be directed forwardly to the return chute 74 and ejected from the cigarette vending machine to the tray 19 for recollection by the purchaser . on the other hand , if a proper selection is made through the pulling and release of the selection knob 17 , the coin door 72 will be lowered to allow the coin currency collected between the coin doors 71 , 72 to be directed to a collection chute 76 and a coin collection box ( not shown ) therebelow . as seen in fig5 the basic mechanical totalizer unit 10 has been altered to provide a modified totalizer unit 110 by the removal of certain components therefrom and the retention of other components therein for use in conjunction with the preferred paper and coin currency totalizer system 41 for the disposition of packs 13 of cigarettes from the existing cigarette vending machine 9 which includes the existing mechanical dispensing mechanism . specifically , the coin recorder mechanism 14 and trip wire 16 with its extended finger 18 have been removed from the modified totalizer unit 110 . additionally , the three latch release bars 22 and associated connecting elements 28 to the release latches 30 , 32 , 34 have been removed . consequently , the three release latches 30 , 32 , 34 are positioned in a &# 34 ; non - released &# 34 ; position with the respective release means ( not shown ) in a position to prevent movement of any of the selection knobs 17 . with the actuation cam 42 temporarily removed from the actuation shaft 40 , the release arm 50 , spring 60 and springs 56 which previously extended to the first ends 24 of the latch release bars 20 are also removed from the totalizer unit 10 . still further , the two coin doors 71 , 72 and the lower walls 75 have also been removed from the totalizer unit 10 to complete the formation of the modified totalizer unit 110 . removal of the coin recorder mechanism 14 , trip wire 16 , latch release bars 22 , connecting elements 28 , release arm 50 , springs 56 and 60 , doors 71 and 72 , and lower walls 75 is simple and within the capability of the owner - operator . the removal is accomplished with simple hand tools by the removal of mounting screws and / or bolts . none of the components which are removed from the modified totalizer unit 110 are welded or secured in place to prevent their simple , convenient removal by those skilled in the vending machine art . it is significant to note that the coin chute assembly 12 , which is quite difficult to remove , is retained in the modified totalizer unit 110 although only the quarter chute 80 will eventually be used . the nickel and dime chutes will not be employed because , with the new means of utilizing both paper and coin currency in the preferred paper and coin totalizer system 41 for the vending of cigarettes , only quarters would be employed . consequently , with a proper adjustment of the coin selector and slug rejecter device ( not shown ) above the modified totalizer unit 110 , only quarters will be advanced to the coin chute assembly 12 for passage through the quarter chute 80 . also remaining in the modified totalizer unit 110 are the reset lever 62 and associated reset linkage 70 . although , as will be seen , the reset linkage 70 and movement thereof is not essential to the operation of the modified totalizer unit 110 , the reset lever 62 will be employed . as seen in fig6 the modified totalizer unit 110 has been employed for the desired modification of the vending machine 9 to operate in conjunction with the preferred paper and coin currency totalizer system 41 of the present invention . specifically , the remaining components thereof are necessary for determining if a proper number of quarters have been deposited in the cigarette vending machine 9 , for producing the desired movement of the release means ( not shown ) which will allow the selection knob 17 to be pulled for the dispensing of the selected pack 13 of cigarettes , and for mechanically determining when a selection has been made . the modified totalizer unit 110 is configured to include a modification support framing 112 which is installed in the totalizer unit 10 in the area of the doors 71 , 72 and lower walls 75 . the support framing 112 includes mounting screws or the like which can , for example , be aligned with existing threaded holes for the lower walls 75 removed from the modified totalizer unit 110 for simple installation therein . after the support framing 112 is installed in the modified totalizer unit 110 , the actuation cam 42 can be reinstalled on the actuation shaft 40 . the modification support framing 112 includes four major components which are configured to function with the existing components remaining within the modified totalizer unit 110 . a quarter chute extension 114 of the modification support framing 112 is aligned with the lower end of the quarter chute 80 to cause each quarter passing therethrough to be properly oriented for passage through the quarter chute extension 114 . after a quarter has passed through the quarter chute extension 114 , it is further directed to the right , as seen in fig6 through the collection chute 76 for collection in the coin collection box ( not shown ) therebelow . however , as the quarter passes through the quarter chute extension 114 , it is maintained in alignment for passage by the coin currency sensor 115 of the totalizer system 41 . the preferred coin currency sensor 115 is a optic device 116 which is capable of determining the movement of each quarter passing thereby . the optic device 116 senses each quarter and provides a signal through first wiring 144 , to be discussed hereinbelow , for transmitting a coin signal to the currency totalizer control means 37 of the preferred totalizer system 41 . the total amount of coin currency passing by the optic device 116 can be electronically combined in the currency totalizer control means 37 , and printed circuit board thereof , with a paper signal indicative of the paper currency deposited in the paper currency verification and sensing means 39 for determining if a total amount of currency has been properly deposited in the paper slot 33 of the attached box 25 and / or directly into the coin slot 15 of the cigarette vending machine 9 . the current amount of the currency deposited in the slots 15 , 33 will be shown on the currency display 35 at the front of the box 25 . after the proper amount of coin and paper currency has been deposited in the cigarette vending machine 9 and / or box 25 , the printed circuit board of the currency totalizer control means 37 indicates the proper amount on the currency display 35 to confirm the proper deposit of currency and produces a desired actuation signal indicating that a selection can be made by the purchaser . when the purchaser has deposited a proper amount of paper and / or coin currency , a selection can be made by using the same existing mechanical dispensing mechanism in the cigarette vending machine 9 as discussed hereinabove . initial movement of a selection knob 17 will cause a lifting of the reset lever 62 by the rotation of the actuation cam 42 . however , while the actuation cam 42 in the totalizer unit 10 , prior to the modification , caused movement of the release arm 50 and the various latch release bars 22 , their removal would prevent this means for providing downward movement of the release latches 30 , 32 , or 34 to position the release means to the release position . instead , the modified totalizer unit 110 includes a entirely different actuation means 119 of the preferred totalizer system 41 in the form of a release solenoid 120 having a release connection 122 extending to the release latch 30 . the release solenoid 120 is mounted on the support framing 112 prior to its installation within the modified totalizer unit 110 . no connection means is provided for the release latch 32 or the release latch 34 . consequently , for the cigarette vending machine 9 which is modified by the preferred system 41 for accepting paper and / or coin currency for the dispensing of packs 13 of cigarettes , all of the packs 13 of cigarettes stored therein will be similarly priced so that the same amount of money will be required for each pack 13 therein . as a result , the mechanical dispensing mechanism in the cigarette vending machine 9 will be configured so that all of the selection knobs 17 , when being pulled , will be prevented from actually dispensing a pack 13 of cigarettes if the single release means ( not shown ) associated with the release latch 30 has not been moved to the release position . the modification or configuration of the mechanical dispensing mechanism to only allow movement of particular selection knobs 17 if the release means is in the release position has been well known to those skilled in the vending machine art prior to any modification of the machines 9 by the present invention and would be the same after the modification of the machine 9 to operate in conjunction with the preferred system 41 . as a result , when the release latch 30 has been moved by the actuation of the release solenoid 120 by the actuation signal from the currency totalizer control means 37 and downward movement of the release connection 122 , the movement of its associated release means to the release position will allow any of the selection knobs 17 to be pulled to a sufficient extent that the selected pack 13 of cigarettes can be dispensed . if a proper amount of paper and / or coin currency has been deposited and a proper selection has been made by the purchaser pulling a selection knob 17 , the selection knob 17 will be released for return to the non - selected position . upon the release of the selection knob 17 , the actuation shaft 40 and actuation cam 42 will return to the position as shown in fig4 and 6 . with the reset lever 62 having been rotated in a clockwise direction and then in a counter - clockwise direction about pivot 64 , the upward and downward movement thereof is indicative of one of the selection knobs 17 having been pulled . accordingly , the preferred currency totalizer control means 37 operates in conjunction with the preferred reset sensor 129 which is configured to sense such a physical movement in the modified totalizer unit 110 . the preferred reset sensor 129 , in the form of a reset switch 130 , which is also mounted on the modification support framing 112 , is positioned to sense the movement of the reset lever 62 . as the reset lever 62 moves clockwise away from the reset switch 130 , the movement is sensed by the reset switch 130 and , upon return to the position as shown in fig6 the reset switch 130 provides a reset signal to the currency totalizer control means 37 to indicate a selection has been made and that no currency has yet been received for the next selection . also associated with the modification support framing 112 is a wiring harness 140 as shown in fig3 and 6 . the wiring harness 140 has an end coupling 142 thereon for easy connection to the corresponding wiring harness 29 from the printed circuit board of the currency totalizer control means 37 in the box 25 . the wiring harness 140 includes the first wiring 144 for coupling the printed circuit board to the quarter optic device 116 for the transmission of the coin signal therefrom . similarly , second wiring 146 connects the printed circuit board to the release solenoid 120 for the transmission of the actuation signal to cause movement of the release connection 122 and release latch 30 for movement of the release means to the release position . finally , third wiring 148 connects the reset switch 130 to the printed circuit board for indication that a selection has been made and the entire printed circuit board is to be returned to the &# 34 ; zero &# 34 ; condition to require additional paper and / or coin currency to be deposited therein for the next selection of a pack of cigarettes . as thus described , the preferred paper and coin currency totalizer of the present invention can be easily installed on existing cigarette vending machines by the modification of the mechanical coin totalizer units thereof and the addition of the attached box including a paper currency verification and sensing means and a preferred currency totalizer control means . while it should be clear from the description provided hereinabove that the preferred paper and coin currency totalizer system 41 is intended to be capable of receiving both coin currency through the slot 15 and paper currency through the slot 33 , the actual amount of the currency required can be selectively varied . the preferred currency totalizer control means includes the printed circuit board described hereinabove having a capability of totalizing an amount of currency from $ 0 . 25 to $ 7 . 75 . the actual amount of the total currency needed to dispense a pack of cigarettes is determined , for example , by the setting of various
