function peripheral ) 4 and an administrative computer ( administrative pc ) 5 by a first route rt 1 ( such as the internet ) via a communication network 2 and a second route rt 2 ( having a larger transmission capacity ) via a downloading server 3 . various control programs as used by the mfp 4 of this program management system 100 ( any program other than the control program may be used but the control program is used in this embodiment ) are automatically made version - up depending on switchable setting contents . in this embodiment , such a switching operation of the setting contents is performed by selecting one of patterns a , b , c and d as described later on . as shown in fig2 , the mfp 4 comprises : an image reading section 41 ; an image forming section 42 , a first communication interface ( nic ) 43 connected to a public switched telephone network ( pstn ); a second communication interface ( modem ) 44 connected to a lan or the internet ; a mfp controlling section 45 including a cpu as a main component ; a storage section 46 ; a displaying section 47 ; and an operator control panel 48 . the storage section 46 in this embodiment comprises : a control program storing region 46 a ; a set - value storing region 46 b ; an image data storing region 46 c ; a mode setting storing region 46 d ; a version - up setting program storing region 46 e ; and a version updating program storing region 46 f . in this mfp 4 , the image reading section 41 and the image forming section 42 cooperates to perform a copier function , the image forming section 42 and the first communication interface 43 cooperates to perform a printer function ; the image reading section 41 and the second communication interface 44 cooperates to perform a facsimile transmitting device function ; and the image forming section 42 and the second communication interface 44 cooperates to perform a facsimile receiving device function . as shown in fig3 , the administrative computer 5 comprises : a pc controlling section 51 including a cpu as a main component ; a first communication interface ( nic ) 53 ; a second communication interface ( modem ) 54 ; a storage section 56 ; a displaying section 57 ; and a key board 58 . the storage section 56 in this embodiment comprises : a version - up program storing region 56 a ; a version managing data storing region 56 b ; a pc controlling program storing region 56 c . in this case , the version - up program storing region 56 a stores therein a version - up program to be executed in the administrative computer 5 when the version - up operation of a control program is made . hereinafter , it will be described how a pattern as a mode for executing a version - up operation of a control program for the mfp in the program management system is set and how that pattern is executed with reference to fig4 and 5 . fig4 is a flow chart illustrating an operation of an mode setting for determining which pattern should be used to execute or perform the version - up operation of the control program for the mfp in the program management system as shown in fig1 . although it may be possible to set or determine such a pattern by one of the version management server 1 , the mfp 4 or the administrative computer 5 , the mfp 4 , among others , is employed for that purpose in this embodiment . in response to any instruction , the mfp controlling section 45 activates the version - up setting program stored in the version - up setting program region 46 e of the storage section 46 . in step ss 1 , it is decided whether or not its activation is completed . if the activation has been completed , then the version - up patterns a , b , c and d are displayed on the operator control panel 48 so that it is prompted which pattern on the panel should be selected in step ss 2 . then , in step ss 3 , it is decided if there was an input for selecting one of the version - up patterns a , b , c and d as displayed on the operator control panel 48 . if there was such a selective input , then it is decided in step ss 4 whether or not that input was to select the pattern a . if so , then the pattern a ( for example , 00h ) will be stored in the mode setting storing region 46 d of the storage section 46 in step ss 5 . however , if it has been decided in step ss 4 that the input was not to select the pattern a , then it is decided in step ss 6 if there was an input for selecting the pattern b . if the input was to select the pattern b , then the pattern b ( for example , 01h ) will be stored in the mode setting storing region 46 d of the storage section 46 in step ss 7 . however , if it has been decided in step ss 6 that the input was not to select the pattern b , then it is decided in step ss 8 if there was an input for selecting the pattern c . if the input was to select the pattern c , then the pattern c ( for example , 10h ) will be stored in the mode setting storing region 46 d of the storage section 46 in step ss 9 . however , if it has been decided in step ss 8 that the input was not to select the pattern c , then it is decided that there was an input for selecting the pattern d . the pattern d ( for example , 11h ) will be stored in the mode setting storing region 46 d of the storage section 46 in step ss 10 . thus , either one of the pattern a , b , c or d is stored in the mode setting storing region 46 d of the storage section 46 and then this flow is ended . next , an operation of reading one of the patterns a , b , c or d and deciding it as a mode setting after the pattern setting for the version - up is completed as shown in fig4 will be described with reference to fig5 . the mfp controlling section 45 of the mfp 4 decides in step sg 1 whether or not an execution command of the version - up operation is present . if it has been decided that that execution command was present , then the mode setting stored in the mode setting storing region 46 d is read in step sg 2 and then it is decided in step sg 3 whether or not the mode setting is the pattern a . as a result of the decision in step sg 3 , if the pattern a has been decided to be the mode setting , then the version - up operation will be executed according to the pattern a , as described later on , in step sg 4 . however , if the pattern a has not be decided to be the mode setting , then it is decided in step sg 5 whether or not the mode setting is the pattern b . as a result of the decision in step sg 5 , if the pattern b has been decided to be the mode setting , then the version - up operation will be executed according to the pattern b , as described later on , in step sg 6 . however , if the pattern b has not be decided to be the mode setting , then it is decided in step sg 7 whether or not the mode setting is the pattern c . as a result of the decision in step sg 7 , if the pattern c has been decided to be the mode setting , then the version - up operation will be executed according to the pattern c , as described later on , in step sg 8 . also , as a result of the decision , if the pattern c has not been decided to be the mode setting , then the pattern d is so decided and the version - up operation will be executed according to the pattern d , as described later on , in step sg 9 . next , the version - up operation of the control program to be executed according to any one of the patterns a , b , c or d will be described in detail with reference to fig6 , 8 or 9 . ( 1 ) pattern a ( full - automatic type as referred to fig6 ) when the mfp 4 updates a program version according to the current control program stored in the control program storing region 46 a of the storage section 46 , it refers to the mode setting storing region 46 d and identifies the mode setting to be the pattern a . then , the mfp 4 instructs the version management server 1 via the communication network 2 of the route rt 1 to transmit an update version of the control program in step sa 1 . the version server 1 transmits to the downloading server 3 the instructed update version of the control program via the route rt 2 , and then the mfp 4 receives from the downloading server 3 the update version of the control program transmitted thereto in step sa 2 . then , the mfp 4 updates with the update control program thus received the current control program stored in the control program storing region 46 a of the storage section 46 in step sa 3 and change the version number in the version managing data storing region 56 b of the administrative computer 5 into an update number in step sa 4 . from now on , the mfp controlling section 45 will control various sections in the mfp 4 according to the update - version control program as above . accordingly , in the case that this pattern a is set , the mfp 4 automatically replaces the current control program with the update - version control program based on the execution command of the version - up operation while the administrative computer 5 updates the version number stored in the version management data storing region 56 b thereof without notifying the administrator on the user &# 39 ; s side . in particular , as far as this pattern a is concerned , it may be possible not to provide the administrative computer 5 with any information regarding replacement . the setting of this pattern a is sufficiently satisfactory for the administrative computer 5 if the administrative computer 5 on the user &# 39 ; s side is not fully capable of dealing with such a replacement . ( 2 ) pattern b ( automatic type as referred to fig7 ) when the mfp 4 updates a program version according to the current control program stored in the control program storing region 46 a of the storage section 46 , it refers to the mode setting storing region 46 d and identifies the mode setting to be the pattern b . then , the mfp 4 instructs the version management server 1 via the communication network 2 of the route rt 1 to transmit an update version of the control program in step sb 1 . the version server 1 transmits to the downloading server 3 the instructed update version of the control program via the route rt 2 , and then the mfp 4 receives from the downloading server 3 the update version of the control program transmitted thereto in step sb 2 . then , the mfp 4 updates with the update control program thus received the current control program stored in the control program storing region 46 a of the storage section 46 in step sb 3 , and notifies the version management server 1 of the completion of the updating operation in sb 4 . in order to notify the mfp 4 of the completion of a job performed in association with the version - up of the control program , the version management server 1 transmits to the mfp 4 a table of a job - completion notification via the route r 1 , as a result of which the mfp 4 receives it in step sb 5 . from now on , the mfp controlling section 45 of the mfp 4 will control various sections in the mfp 4 according to the update - version control program as above in step sb 6 . also , the mfp 4 notifies the administrative computer 5 of the job - completion notification table thus received . in the administrative computer 5 thus notified of , the pc controlling section 51 which usually performs a control according to the pc controlling program stored in the pc controlling program storing region 56 c controls , upon activation of a version - up operation according to the pattern b , the displaying section 57 to display thereon the content of the job - completion notification table according to the version - up program stored in the version - up program storing region 56 a . what are updated at this time are a display as shown in fig1 and the content stored in the displaying section and the storage section 56 as , inclusive of an update of a version number stored in the version managing data storing region 56 b . fig1 illustrates : model numbers mdl 10 , mdl 33 , mdl 50 and mdl 87 corresponding to respective control programs ; their serial numbers ; old version numbers ; updated ( new ) version numbers ; and version - up contents where is appropriate . in the case of the pattern b being set , the mfp 4 will automatically replace the current control program with an update version one according to an execution command of the version - up and simultaneously render an information concerning that replacement to the administrative computer 5 . namely , the setting of the pattern b is appropriately enabled if the administrative computer 5 on the user &# 39 ; s side is fully capable of dealing with such a replacement , with a result that more elaborate capability can be accomplished as compared with the setting of the pattern a . ( 3 ) pattern c ( push - manual type as referred to fig8 ) the mfp 4 receives a table of a version - up query ( as shown in fig1 ) which is transmitted from the version management server 1 and which compares the current version with an update version in step sc 1 . since the mfp 4 can identify the pattern c as the set mode by referring to the mode setting storing region 46 d , the mfp 4 transfers the received version - up query table to the administrative computer 5 in step sc 2 . then , the administrative computer 5 controls the display section 57 to display thereon the transferred version - up query table . here , if there is any model of an update version , the administrative computer 5 ask the administrator a query whether or not the model should be updated . in response to that query , if the version - up is desired , a symbol “ x ” as a check mark will be inputted in a check box as shown in fig1 . hence , as an operation of that version - up is commanded , the administrative computer 5 transmits such an input information to the mfp 4 . the mfp 4 decides in step sc 3 whether or not there is any answer about an update in the input information transmitted from the administrative computer 5 . if there is such an answer , the mfp 4 decides in step sc 4 whether or not there is any model required to be updated . if it has been decided there is no model required to be updated , the mfp 4 will conduct a notification to the version management server 1 that the control program is not to be updated in step sc 11 , thereby this flow being ended . however , if it has been decided there is any model required to be updated , the mfp 4 will request the version management server 1 via the route rt 1 to transmit a control program of the update version for its corresponding model in step sc 5 , and receive that update - version control program transmitted via the route rt 2 in step sc 6 . then , the mfp 4 which has already received the update - version control program will update with the update - version control program the current control program previously stored in the control program storing region 46 a of the storage section 46 in step sc 7 . after that update , the mfp 4 notifies the version management server 1 of the program updating operation being completed in step sc 8 . in order to notify the mfp 4 of the completion of a job which has been executed in association with the version - up operation of the control program , the version management server 1 which has been notified of the completion of the updating operation transmits to the mfp 4 via the route rt 1 a table of a job - completion notification ( as shown in fig1 ), as a result of which the mfp 4 receives it in step sc 9 . from now on , the mfp controlling section 45 of the mfp 4 will control various sections in the mfp 4 according to the update - version control program as above . also , the mfp 4 notifies the administrative computer of the job - completion notification table thus received . in the administrative computer 5 thus notified of , the pc controlling section 51 which usually performs a control according to the pc controlling program stored in the pc controlling program storing region 56 c controls , upon activation of the version - up operation according to the pattern b , the displaying section 57 to display thereon the content of the job - completion notification table according to the version - up program stored in the version - up program storing region 56 a . what are updated at this time are a display as shown in fig1 and the content stored in the version managing data storing region 56 b of the storage section 56 , inclusive of an update of a version number stored in the version managing data storing region 56 b , and then this flow is ended . in the case of the pattern c being set , the mfp 4 receives a table of a version which is transmitted from the version management server 1 and which compares the current version with an update version and transfer it to the administrative computer 5 so as to be displayed on the display section 57 . if there is any model of the update version , the administrative computer 5 ask the administrator a query whether or not the model should be updated . accordingly , if the administrator is in an situation in which administrator can normally operate the administrative computer 5 , the user can control the administrative computer 5 to execute an appropriate version - up operation in a correspondence manner to the actual situation , or otherwise not to execute a version - up operation if there is any inconvenience . ( 4 ) pattern d ( push - manual type as referred to fig9 ) when the mfp 4 updates a program version according to the control program stored in the control program storing region 46 a of the storage section 46 , it refers to the mode setting storing region 46 d and identifies the mode setting to be the pattern d . then , the mfp 4 requests the version management server 1 via the route rt 1 to transmit a version information indicating whether or not there is any change in the control program in step sd 0 . the version management server 1 which has received such a request transmits to the mfp 4 via the route rt 1 a table of version ( as referred to fig1 ) which compares the current version with an update version , while the mfp 4 receives the version table via the communication network 2 of the route rt 1 in step sd 1 . since the mfp 4 has already identified the mode setting to be the pattern d , it transfers the received version table to the administrative computer 5 in step sd 2 . then , the administrative computer 5 controls the display section 57 to display thereon the transferred version table . here , if there is any model of the update version , the administrative computer 5 ask the administrator a query whether or not the model should be updated . in response to that query , if the version - up is desired , a symbol “ x ” as a check mark will be inputted in a check box as shown in fig1 . hence , as an operation of that version - up is commanded , the administrative computer 5 transmits such an input information to the mfp 4 . then , the mfp 4 decides in step sd 3 whether or not there is any answer about an update in the information transmitted from the administrative computer 5 . if there is such an answer , the mfp 4 decides in step sd 4 whether or not there is any model required to be updated . if it has been decided there is no model required to be updated , the mfp 4 will conduct a notification to the version management server 1 in step sd 11 that the control program is not to be updated and this flow is ended . however , if it has been decided there is any model required to be updated , the mfp 4 will request the version management server 1 via the route rt 1 to transmit a control program of the update version for its corresponding model in step sd 5 , and receive that update - version control program transmitted via the route rt 2 in step sd 6 . then , the mfp 4 which has received the update - version control program will update with the update - version control program the current control program previously stored in the control program storing region 46 a of the storage section 46 in step sd 7 . after that update , the mfp 4 notifies the version management server 1 of the program updating operation being completed in step sd 8 . in order to notify the mfp 4 of the completion of a job which has been executed in association with the version - up operation of the control program , the version management server 1 which has been notified of the completion of the updating operation transmits to the mfp 4 via the route rt 1 a table of a job - completion notification ( as shown in fig1 ), as a result of which the mfp 4 receives it in step sd 9 . from now on , the mfp controlling section 45 of the mfp 4 will control various sections in the mfp 4 according to the update - version control program as above . also , the mfp 4 notifies the administrative computer 5 of the job - completion notification table thus received . in the administrative computer 5 thus notified of , the pc controlling section 51 which usually performs a control according to the pc controlling program stored in the pc controlling program storing region 56 c controls , upon activation of the version - up operation according to the pattern d , the displaying section 57 to display thereon the content of the job - completion notification table according to the version - up program stored in the version - up program storing region 56 a . what are updated at this time are a display as shown in fig1 and the content stored in the version managing data storing region 56 b of the storage section 56 , inclusive of an update of the version number stored in the version managing data storing region 56 b , and then this flow is ended . in the case of the pattern d being set , the mfp 4 requests the version management server 1 and receives therefrom a table of version - up query ( as referred to fig1 ), which compares the current version with the update version where is necessary according to the administrator &# 39 ; s situation . then , the mfp 4 transfers the version - up query table to the administrative computer 5 to be displayed on the display section 57 . if there is any model of the update version , the administrator is given a query whether or not the model should be updated . accordingly , the administrator is capable of performing the version - up operation at the administrator &# 39 ; s convenience when he / she can operate the administrative computer 5 . otherwise , it is also possible not to perform the version - up operation at the time , e . g ., when the administrator is in an inconvenient situation . in association with each version - up query of the patterns c and d , the table as shown in fig1 is firstly configured to be displayed on the administrative computer 5 in the above embodiment , the present invention is not limited to this configuration . in the contrary , the table as shown in fig1 may firstly be configured to be displayed on the administrative computer , thereby taking off an unnecessary check mark “ x ” from the check box . also , even if a plurality of the models are all enabled to be made version - up , it is possible to give a permission only one of them to be made version - up . fig1 is a block diagram illustrating one example of more specifically implementing the program management system as shown in fig1 . in this case , a version management server 110 is connected to a mfp ( multi - function peripheral ) and an administrative computer 150 as devices on the user side , via a first route rt 1 ( such as the internet ) as a communication network comprising wans 121 , 123 and 125 , a management server 122 and a distributor 124 , and via a second route rt 2 ( having a larger transmission capacity ) comprising a downloading server 130 . the mfp 140 and administrative computer 150 as user - side devices in this example are connected to the first route rt 1 and second routes rt 2 via a firewall 141 . the administrative computer 150 , on the other hand , is connected to the first route rt 1 via the public switched telephone network ( pstn ) and the wan 125 . in this example , it is assumed that the management server 122 is located ( in a foreign country or ) distant from the version management server 110 . it will be understood by those skilled in the art that the program management systems as shown in fig1 and 13 are configured to update a control program ( an object to be updated ), but it is possible to update the other programs or setting values in a similar fashion . further , both of the first and second routes rt 1 and rt 2 are configured to be used as the communication networks , but it is possible to use only one route such as the internet . furthermore , the embodiments as described above are configured to use a mfp as an object to be made version - up , but the present invention is not limited to this . the version - up operation according to the present invention is also applicable to business machines inclusive of a administrative computer as well as a copying machine and a fax machine ( an object to be updated ). in the program management system according to the present invention as described above , the user of a multi - function peripheral device is capable of performing a version - up operation of a program of the multi - function peripheral device according to a pattern set by pattern setting means setting therein that pattern as an optimum one suitable for a user &# 39 ; s situations or affairs . thus , when the version - up operation is activated , program updating means will automatically perform the version - up operation of the program of the multi - function peripheral device according to the optimum and selected pattern set by the pattern setting means , thereby satisfying user &# 39 ; s requirements .
