Whether or not the image forming apparatus 20 itself owns the application to which the associated application ID is attached in the application ownership device information 27g (hereinafter referred to as "target application" in the explanation of FIGS. 14 to 16). (S181). Here, the application execution unit 28d executes an image forming apparatus (hereinafter referred to as "target image forming apparatus" in the description of FIGS. 14 to 16) that is associated with the icon ID of the target icon in the application ownership device information 27g. ) is the image forming apparatus 20 itself, it is determined that the image forming apparatus 20 itself owns the target application. On the other hand, if the target image forming apparatus is not the image forming apparatus 20 itself, the application execution unit 28d determines that the image forming apparatus 20 itself does not own the target application.

When the application execution unit 28d confirms in S181 that the image forming apparatus 20 itself owns the target application, it executes the target application (S182).

After the process of S182, the installation execution unit 28a increases the number of times the target application has been used by one in the application ownership device determination information 27i (S183).

After the process of S183, the installation execution unit 28a executes an application ownership optimal device information update process to update the application ownership optimal device information 27j (S184).

After the process of S184, when the setting value of the target application is changed, the application execution unit 28d executes the Manifest. Setting values in the application setting data included in the MF are changed (S185). The process of S185 is executed every time the setting value of the target application is changed.

When the installation execution unit 28a confirms in S181 that the image forming apparatus 20 itself does not own the target application, it requests the target image forming apparatus for an installation file for the target application (S186). The request in S186 includes the serial number of the image forming apparatus 20 and the application ID of the target application. The following description will be made assuming that the target image forming apparatus is the image forming apparatus 30.

Upon receiving the request in S186, the file transmitting unit of the image forming apparatus 30 determines whether the serial number of the image forming apparatus 20 that is the request source in S186 is included in the ACD file of the application that is the target of the request in S186. Confirm (S187).

When the file transmission unit of the image forming apparatus 30 determines in S187 that the ACD file includes the serial number of the image forming apparatus 20, it packages the target application into a PKG format file that can be installed on the image forming apparatus. (S188).

FIG. 17 is a diagram showing an example of the PKG format file 70 packaged in S188.

A PKG format file 70 shown in FIG. 17 includes an application executable file 71 and a Manifest. MF72. Manifest. The MF 72 includes application data 72a indicating information such as the name of the application and the application ID, and application setting data 72b indicating various setting values of the application.

As shown in FIGS. 14 to 16, after the process in S188, the file transmission unit of the image forming apparatus 30 transmits the PKG format file packaged in S188 to the image forming apparatus 20 that is the request source in S186 ( S189).

When the installation execution unit 28a of the image forming apparatus 20 receives the PKG format file transmitted in S189, it installs the target application using the received PKG format file (S190). Here, the installation execution unit 28a applies the setting values indicated in the application setting data included in the PKG format file.

After the process of S190, the installation execution unit 28a stores the remaining memory amount after installing the target application in S190 in the application ownership device determination information 27i (S191).

After the process of S191, the application execution unit 28d executes the target application (S192).

After the process of S192, the installation execution unit 28a increases the number of times the target application has been used by one in the application ownership device determination information 27i (S193).

After completing the process of S193, the installation execution unit 28a uninstalls the target application from the image forming apparatus 20 (S194).

The installation execution unit 28a stores the application ID of the target application, the serial number of the image forming apparatus 20 itself, the remaining memory capacity and the number of times the application has been used that are associated with the target application in the application ownership determination information 27i. and is transmitted to the image forming apparatus 30 (S195).

Upon receiving the information transmitted from the image forming apparatus 20 in S195, the installation execution unit of the image forming apparatus 30 executes an application ownership optimum device information update process (S196).

When the activation execution unit of the image forming apparatus 30 determines in S187 that the ACD file does not include the serial number of the image forming apparatus 20, the activation execution unit of the image forming apparatus 30 issues an image request for an activation key for the image forming apparatus 20 to the target application. The forming device 20 is notified (S197).

Therefore, the activation execution unit 28b of the image forming apparatus 20 notifies the target application of a request for an activation key for the image forming apparatus 20 via the display unit 22 of the image forming apparatus 20 (S198).

Therefore, the user can input the activation key requested in S198 via the operation unit 21 of the image forming apparatus 20. Note that if the user is not the developer 80, the user obtains an activation key from the developer 80.

When the activation key is input after the process of S198, the activation execution unit 28b of the image forming apparatus 20 transmits the input activation key and the serial number of the image forming apparatus 20 itself to the image forming apparatus 30. Notify (S199).

Upon receiving the notification in S199, the activation execution unit of the image forming apparatus 30 determines whether the activation key notified in S199 is appropriate (S200). Here, the activation execution unit of the image forming apparatus 30 notifies the information generated according to a specific rule based on the application ID of the target application and the serial number of the image forming apparatus 20 notified in S199. If the activation key matches the received activation key, it is determined that the activation key notified in S199 is appropriate. On the other hand, the activation execution unit of the image forming apparatus 30 is notified in S199 of information generated according to a specific rule based on the application ID of the target application and the serial number of the image forming apparatus 20 notified in S199. If the activation key does not match the received activation key, it is determined that the activation key notified in S199 is not appropriate.

When the activation execution unit of the image forming apparatus 30 determines in S200 that the activation key notified in S199 is appropriate, it writes the serial number of the image forming apparatus 20 into the ACD file of the target application (S201). Here, the activation execution unit of the image forming apparatus 30 also increases the value of the number of machines in the ACD file of the target application by one.

After the process in S201, processes in S188 to S196 are executed.

If the activation execution unit of the image forming apparatus 30 determines in S200 that the activation key notified in S199 is not appropriate, it notifies the image forming apparatus 20 that the target application cannot be executed (S202). ).

Therefore, the activation execution unit 28b of the image forming apparatus 20 notifies the user via the display unit 22 of the image forming apparatus 20 that the target application cannot be executed (S203). Therefore, the user of the image forming apparatus 20 can recognize that the target application cannot be executed on the image forming apparatus 20.

If the installation execution unit 28a determines in S224 that the remaining memory amount associated with the target application in the application ownership device determination information 27i is not less than a specific threshold, the installation execution unit 28a determines the application ownership optimum for the target application. It is determined whether the number of times of application usage associated with the device information 27j exceeds the number of times of application usage associated with the target application in the information 27i for determining whether the device owns the application (S225).

The installation execution unit 28a determines whether the number of times of application usage associated with the target application in the application ownership optimum device information 27j is the number of application usages associated with the target application in the application ownership optimal device determination information 27i. If it is determined in S225 that the number is equal to or less than the number of times, the serial number, remaining memory capacity, and number of times of application usage associated with the target application in the application ownership optimal device information 27j are combined with the serial number of the image forming apparatus 20 itself; The remaining memory capacity and the number of times the application has been used are updated to correspond to the target application in the application ownership device determination information 27i (S226), and the operation shown in FIG. 18 ends.

If the installation execution unit 28a determines in S221 that the application ownership optimal device information update process has been started by receiving information from another image forming apparatus, the installation execution unit 28a determines that the remaining memory capacity received from the other image forming apparatus is below a specific threshold. It is determined whether there is one (S227). The threshold value in S227 is the same value as the threshold value in S224.

If the installation execution unit 28a determines in S227 that the remaining memory capacity received from another image forming apparatus is not less than a specific threshold, the installation execution unit 28a installs an application that is associated with the target application in the application ownership optimal device information 27j. It is determined whether the number of times exceeds the number of times of application usage received from another image forming apparatus (S228).

If the installation execution unit 28a determines in S228 that the number of application usages associated with the target application in the application ownership optimal device information 27j does not exceed the number of application usages received from other image forming apparatuses, the installation execution unit 28a installs the target application. The serial number, remaining memory capacity, and number of times the application has been used that are associated with the application in the application ownership optimum device information 27j are compared to the serial number of the other image forming apparatus and the remaining memory capacity received from the other image forming apparatus. and the number of times the application has been used (S229), and the operation shown in FIG. 18 ends.

The installation execution unit 28a determines in S224 that the remaining memory amount associated with the target application in the app ownership device determination information 27i is below a specific threshold, or determines that the target application has an app ownership status. In S225, it is determined that the number of times of application usage associated with the optimal device information 27j exceeds the number of times of application usage associated with the target application in the information 27i for determining whether the device owns the application, or if another image is used. It is determined in S227 that the remaining memory capacity received from the image forming apparatus is below a specific threshold, or the number of times the application has been used that is associated with the target application in the application ownership optimum device information 27j is higher than that of another image forming apparatus. If it is determined in S228 that the number of times the application has been used exceeds the number received from , the operation shown in FIG. 18 ends.

Next, the operation of the image forming system 10 when changing the image forming apparatus that owns the application will be described.
