the check - out counter 10 includes a merchandise unload - check - out module 11 behind which is a bagging module 12 . the two modules are spaced apart a sufficient distance to provide a work space for a checker - cashier . a conveyor belt unit 13 interconnects the two modules . along side the forward check - out module is located a cash register pedestal 14 upon which a cash register 15 is positioned . the forward module preferably includes a conveyor belt 17 supported upon opposite rollers 18 and a suitable support plate 19 located beneath the upper reach of the belt for conveying merchandise from one end of the counter towards the other . typically , customers , such as in a food market , unload their market baskets upon the conveyor belt 17 which is intermittently operated by the checker - cashier to bring the merchandise to her for check - out . the conveyor belt 17 , which is conventional , is operated by a motor drive which is controlled by a cashier actuated switch , such as a floor pedal switch . a flat transition plate 20 is located at the rear end of the module adjacent the checker . the plate may be a flat , solid plate upon which merchandise may be slid manually by the cashier during check - out and bagging . alternatively , a scanner plate may be substituted , that is , a plate with suitable openings for an electronic scanner to automatically read price markings placed upon the merchandise . the counter or module may be made with leg means for raising and lowering its height ( not shown ) so as to accomodate to various heights of scanner units or to provide an optimum height work surface for the cashier . this is a conventional means and therefore is not illustrated here . also , side rails 21 are provided on the module to keep the merchandise upon the conveyor belt and avoid sidewise spillage . the forward module may be made with appropriate cabinet shelving , such as shelf units 22 , and a bagging shelf 23 hinged at 23a for either positioning vertically , i . e ., out of the way , or horizontally so that the check - cashier can do her own bagging with one hand while operating the cash register with the other hand , when desired . the shelf 23 may be supported in horizontal position ( see dotted lines in fig1 , and 3 ) by a conventional releasable brace or bracket 23b schematically shown in fig3 . the rear bagging module 12 includes an upper sloped bagging deck 24 , side rails 25 and a rear rail 26 to receive merchandise from the checker . the module may include a shelf cabinet or portion 27 which may open forwardly and rearwardly to store bags which may be reached either from the front or the rear of the cabinet . the module also includes parallel vertical walls 28 and 29 which form a vertical belt receiving slot or area 30 along side of which is located vertically elongated storage shelf portion 31 for bags or the like . the conveyor belt unit 13 is formed of a frame 33 ( see fig6 ) made of parallel , flat , sheet metal arms 34 and 35 to which are fastened an upper plate 36 and a lower plate 37 for rigidifying the frame . the arms , which are of different lengths , are provided with parallel , vertically elongated aligned slots 38 . a roller 39 is arranged between the arms and the slots and spindles 40 mounted on the ends of the roller fit within the slots for rotation of the roller . the opposite ends of the arms are provided with horizontally elongated slots 41 . a power roller 42 is located between the slotted end portions of the arms and is provided with spindles 43 and 43a which extend through the slots 41 and fit within vertical slots 44 of support brackets 45 which are suitably mounted , as by mounting screws or the like ( not shown ) upon the parallel walls 28 and 29 of the bagging module . thus , the spindles 43 and 43a pivotally support the frame 33 as well as supporting the power roller 42 . an electric motor 48 is located within the power roller ( see fig8 ). the motor is mounted within a cylinder 49 having a bottom 50 connected to spindle 43 . the drive shaft 51 of the motor drives a gear speed reducer 52 ( schematically shown ) which has an output shaft 53 upon which a small gear 54 is mounted . such gear drives a ring gear 55 which is fastened within the roller 42 for rotating the roller relative to the spindles 43a and 43 . the spindle portion 43a connects to the speed reducer for supporting the unit within the roller . an endless belt 57 is arranged around the power roller 42 and the opposite roller 39 for driving the belt . the belt may be operated continuously or alternatively the motor may be actuated by a foot controlled pedal or switch so that the cashier can operate the belt whenever desired . such types of controls are conventional and thus , it is not illustrated here . as can be seen , the arm 34 is longer than the arm 35 in the drawings in order to permit the conveyor belt unit to be arranged at an angle relative to the transverse parallel edges of the forward and rear modules . of course , the arms may be of the same length and thus the belt may be arranged perpendicular to the two units rather than at an angle as shown . the free end of the conveyor unit is defined by a u - shaped bent channel 58 which is angled so as to close the gap between the end of the belt unit and the rear transverse edge of the forward module . as shown in fig5 and 9 , the free edge of the belt unit is latched to the transverse edge of the forward module by means of a downwardly opening u - shaped member 59 which is fastened to the channel 58 and which engages a tongue 60 on a strip which is bent to have a lower edge 61 fastened to the adjacent module edge by means of suitable screws 62 passing through springs 63 . the springs permit forward and rearward movement of the strip 60 so as to permit the cashier - checker to lift the conveyor unit upwardly a short distance and then to manually move the strip 60 forwardly , out of the way . this permits the downwardly bent member 59 to clear the strip and thus permits the conveyor unit to drop downwardly for stowing , that is , for being suspended by the pivot forming spindles 43 and 43a . to prevent the conveyor unit from simply dropping down by gravity and also to make it easier to raise the unit manually , a counter - balancing strut 65 is provided ( see fig1 ). such strut is composed of an elongated cylinder 66 and an elongated rod 67 telescoped within the cylinder and having a piston portion 68 located within the cylinder and abutting one end of a spring 69 located within the cylinder . the upper end of the cylinder is closed by a closure 70 and preferably the cylinder is filled with oil 71 or the like fluid which may pass through one or more openings 72 formed in the piston 68 for thus resisting the movement of the piston within the cylinder and acting as a damper . an eye ring 73 on the free end of the rod 67 is connected by a pin to a bracket or plate 74 fastened to the lower edge of the plate 37 of the frame 33 . likewise , the lower end of the cylinder is provided with a bracket 75 which pivotally connects to a bracket 76 fastened within the floor of the cabinet making up the bagging module . as shown in fig1 , when the conveyor unit is raised , the strut rod 67 is extended from the cylinder so that when the unit is released or dropped , it slowly swings down into the vertical position until it finally reaches an over - center position as indicated by the dotted line 77 in fig1 which thus helps to maintain the conveyor unit in its approximately vertical location and against swinging upwardly without a deliberate pull by the cashier - checker . the counter - balancing strut 65 including spring 69 and strut rod 67 assumes a spring - held , over - the - center relationship as illustrated in fig1 to secure the conveyor unit in a substantially vertical non - operating position . in operation , the cashier - checker is located between the forward and rear modules and may operate the check - out system as a single or double belt counter depending upon the amount of business to be handled . for single belt operation , the conveyor unit 13 is pivoted downwardly , out of the way , and the cashier does her own bagging at the rear end of the forward module . the shelf 23 is so located that the cashier can place merchandise into a bag supported on the shelf while ringing up the cash register with the other hand . the cashier also has access to bags stored in the shelf unit 22 in the forward module , and also those bags stored in the bagging module . for double belt operation , the conveyor unit is swung upwardly so that its end is latched to the forward module . in this position , the cashier moves the merchandise from the transition plate 20 upon the conveyor belt 57 where it is conveyed to the bagging deck 24 . a bagger located at the rear of the bagging module can then place the merchandise into bags . for that purpose , a rear bagging shelf 78 may be provided . ( see fig3 ) if a scanner type of cash register is to be used , its sensing device may be located at or below the transition plate 20 for automatically reading the markings on the merchandise and thereby operating the cash register in response to such readings . the conveyor belt unit may be adjusted to different heights , depending upon the relative heights of the forward module to the rear bagging module . this makes the unit adaptable to various types of scanning cash registers which are now becoming available on the market . the conveyor unit frame side arms 34 and 35 and end channel 58 function as decorative outer surfaces for the belt unit , thus eliminating the need for an outer cover . the frame also contains or bounds all the conveyor parts for support as well as for handling the conveyor as a single piece which can be raised , lowered , removed , replaced , etc . in addition , as illustrated in fig1 , a flat planar surface , i . e . like a large wide board or panel 80 , could be used in place of the belt conveyor unit to act as a slide or manually operated conveyor unit , upon which the merchandise can be manually slid from the forward module to the rear module . in such case , pins 81 , which are secured to brackets 82 fastened to the sides of the panel , fit within and pivotally connect the panel to rear module support brackets 45 , in place of the conveyor unit spindles 43 and 43a . the same u - shaped member 59 as is used on the belt conveyor unit is attached to the free end of the panel for releasable connection to the tongue 60 or strip 61 , for holding the panel in a conveyor - acting position .
a check - out counter formed of a forward check - out module , having a conveyor belt for transporting merchandise along the top thereof , and a rear bagging module having an upper merchandise receiving deck . the two modules are spaced apart and a stowable second conveyor unit is provided to bridge the space when desired to carry merchandise from the check - out module to the bagging module deck . the conveyor unit is formed of a pair of spaced apart rollers mounted upon opposite ends of a support frame and carrying an endless conveyor belt . one end of the unit is pivotally connected to the bagging module and the other end is releasably latched to a rear edge of the check - out module . thus , the unit may alternatively be extended between the modules for conveyor use or may be stowed , hanging downwardly from its pivots in a non - use position .
