The communication processing unit 121 communicates with applications (hereinafter referred to as “external applications”) 231 and 232 respectively mounted on a plurality of external servers 20 (20a, 20b,...) On the network 1 or directly. Communication means for communicating with a connected external device. Note that the external applications 231 and 232 can be directly connected to communicate with them.
In FIG. 6 and subsequent figures, and in Tables 1 and 2, etc., the external application 231 is described as “application 1”, the external application 232 as “application 2”, and the other external applications as “application 3”. , “App 4” and the like.
The application selection unit 122 receives data such as commands (operation execution requests) sent from a plurality of external applications including the external applications 231 and 232, and sends (delivers) the data to the control unit 124. In addition, when data such as an operation instruction is received from the control unit 124, the data is distributed and sent to a plurality of external applications including the external applications 231 and 232. That is, the destination to which the application is sent is determined, and the received data is sent to the destination. Therefore, the application selection unit 122 functions as an application registration unit, an application display unit, and an application selection reception unit. When an application (internal application) is also stored in the ROM 204 or the HDD 206, the same process as the process for the external application can be performed for the application.

  The application information storage unit 123 manages external applications such as the location (IP address) of an available external application, that is, the installation location of the external server 20 on which the external application is installed and the type of external application that can be used. Various information to be stored is stored as an application management table. Thereby, an application that can be used in the MFP 10 can be registered. The application information storage unit 123 exists in the SDRAM 103, the NVRAM 105, or the HDD 106 in FIG. 2, and is changed (updated) whenever information changes. Therefore, the application information storage unit 123 functions as an application registration unit. When an application (internal application) is also stored in the ROM 204 or the HDD 206, the application can be registered in the same manner as the external application.

The control unit 124 comprehensively controls each unit including the communication processing unit 121, the application selection unit 122, the operation unit 107, the application information storage unit 123, and the engine 14, and functions as a control unit.
Therefore, the control unit 124 selects each external application by selectively communicating with the application selection unit 122, the communication processing unit 121, and a plurality of external applications including the external applications 231 and 232 via the network 1. It is possible to realize various functions by using them.

Next, a hardware configuration example of the external server 20 will be specifically described with reference to FIG.
FIG. 7 is a block diagram illustrating a hardware configuration example of the external server 20.
The external server 20 is an information processing apparatus such as a PC (Personal Computer), and as shown in FIG. , IEEE 1394 • I / F 210, MAC • I / F 211, and the like.

Since the configuration of the external server 20 is almost the same as the configuration of the controller 11 described with reference to FIG. 2, only different portions will be described.
The operation unit 207 includes an input device such as a keyboard and a mouse for inputting data such as operation instructions for the MFP 10 and a display device such as an LCD display or a CRT display. For example, a touch panel can be provided on the surface of the display device.

Next, a main functional configuration example of the external server 20 will be specifically described with reference to FIG.
FIG. 8 is a block diagram illustrating a main functional configuration example of the MFP 10 and the external server 20a. For convenience of explanation, the external application 231 is illustrated as including each unit such as an application communication processing unit 241 described later.

The external server 20a has functions as an application communication processing unit 241, an application control unit 242, and a device information storage unit 243. These functions are realized by the CPU 201 shown in FIG. 7 operating according to the external application 231 stored in the ROM 104 and using the MAC / I / F 211, USB / I / F 209, IEEE 1394 / I / F 210 as necessary. It can be done.
The application communication processing unit 241 is a communication unit that communicates with each MFP 10 on the network 1 or communicates with a directly connected MFP.

The application control unit 242 controls the application communication processing unit 241 and the device information storage unit 243, and functions as a control unit.
The device information storage unit 243 is an application storage unit that stores information regarding image processing devices that can be used by the external server 20a. Thereby, an image processing apparatus that can be used by the external server 20a can be registered. This device information storage unit 243 exists on the SDRAM 203, NVRAM 205, or HDD 206 of FIG. 7, and is changed whenever information changes.

  The main functional configuration of the other external server 20b is substantially the same as that of the external server 20a, and thus illustration and description thereof are omitted. In addition, the processes on the external server 20 (20a, 20b,...), That is, the external applications including the external applications 231, 232 are actually executed by the corresponding CPU 201 operating according to the external application. However, for the convenience of explanation, hereinafter, it may be described that the external application executes processing.

  Here, the external application is for realizing various functions. That is, each external application including the external applications 231 and 232 realizes a copy application for realizing a copy function, a printer application for realizing a printer function, a scanner application for realizing a scanner function, or a FAX function. Any application may be used, such as an application for realizing any one function such as a FAX application for the purpose, or a combination of a plurality of types of applications. For example, the external application 231 (external application-1) realizes a basic (low version) copy function and printer function, and the external application 232 (external application-2) realizes a basic scanner function and FAX function. An application for realizing a copy function and a printer function of a high version for another external application (external application-3), and a scanner function and a FAX for a high version of another external application (external application-4) It is good also as an application for realizing a function.

  In addition to the MFP 10, other image processing apparatuses such as a single printer, scanner, digital copying machine, or FAX apparatus can be connected via the network 1 or directly. Although not shown, these image processing apparatuses include a controller having the same configuration as that of the MFP 10 and can perform control (processing) according to the present invention described later.

Next, the control (processing) according to the present invention in the image forming system of the first embodiment configured as described above will be specifically described with reference to FIGS.
[First control example]
First, a first example (basic) of a communication sequence between an MFP 10 and an external application that is an application in the external server 20 when the MFP is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 9 is a diagram illustrating a first example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.

The application selection unit 122 of the MFP 10 is registered with the external applications 231 and 232 registered in advance (indicated by information stored in the application management table of the application information storage unit 123 in FIG. 6) when activated (powered on). Issue an activation notification (MFP activation notification). That is, the communication processing unit 121 sequentially transmits MFP activation notifications to the external applications 231 (1) and 232 (2) (S101 to S104). Each of the MFP startup notice to the external applications 231 and 232, but adds application identification number for identifying the external applications 231 and 232, which is acquired from the application information storing unit 123 of FIG. 6 with app mounting location information.
Here, the application management table stored in the application information storage unit 123 of FIG. 6 will be described with reference to Table 1. In the example of Table 1, four external applications are registered.

このアプリ管理テーブルは、例えばネットワーク１上のアプリ毎に、アプリ名，アプリが存在する場所を示すアプリ場所情報（アプリのＩＰアドレス），およびアプリの種類を対応付けて記憶（登録）している。この例では、外部アプリ２３１（１）と外部アプリ２３２（２）をコピーアプリ、図示しない他の外部アプリ（３）をプリンタアプリ、図示しない更に他の外部アプリ（４）をスキャナアプリとする。但し、コピーアプリである外部アプリ２３１，２３２であるが、例えば外部アプリ２３１の方がバージョンが高い（最新バージョンである）ものとする。

This application management table stores (registers) an application name, application location information (application IP address) indicating a place where the application exists, and an application type in association with each other on the network 1, for example. . In this example, the external application 231 (1) and the external application 232 (2) are a copy application, another external application (3) (not shown) is a printer application, and another external application (4) (not shown) is a scanner application. However, although the external applications 231 and 232 are copy applications, for example, it is assumed that the external application 231 has a higher version (the latest version).

Returning to the description of FIG.
When the external server 231 on which the external application 231 is installed is activated, when the external application 231 receives an MFP activation notification from any MFP 10, the application availability notification including its own identification information as a response to the notification (Application 1 availability notification) is transmitted to the corresponding MFP 10 (the MFP 10 that transmitted the MFP activation notification) (S105).
When the external application 232 also receives the MFP activation notification from the MFP 10 when the external server 20b on which the external application 232 is installed is activated, an application availability notification including identification information of its own application as a response to the notification ( Application 2 availability notification) is transmitted to the MFP 10 (S107).

  When the communication processing unit 121 receives the application 1 availability notification from the external application 231 and the application 2 availability notification from the external application 232 by the communication processing unit 121, the application selection unit 122 of the MFP 10 receives the application identification information added to the notifications. Thus, it can be determined whether or not the external applications 231 and 232 can be used. In this processing example, since both of the external applications 231 and 232 can be used, the external application 231 is set to “permitted” by setting “permitted” for the corresponding application use in the application management table of the application information storage unit 123. , 232 are registered as available applications (S106, S108).

After that, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S109), the content of the application management table in the application information storage unit 123 is referred to and used from the available applications. By selecting (determining) an application to be used (in this case, the external application 231 (1)) and storing information on the application to be used in the application information storage unit 123 as a use application management table, the external application 231 is stored. Register as an application that uses (1). Then, the received operation instruction is transmitted to the external application 231 by the communication processing unit 121 (S110, S111).
Here, the use application management table will be described with reference to Table 2.

この利用アプリ管理テーブルは、利用するアプリ毎に、アプリの種類およびアプリ名を対応付けて記憶している。この表２に示した利用アプリ管理テーブルは、３つの外部アプリを利用するアプリとして登録した例を示している。

This application management table stores an application type and an application name in association with each application to be used. The use application management table shown in Table 2 shows an example of registration as an application that uses three external applications.

When the external application 231 receives an operation instruction from any of the MFPs 10, it processes the contents of the operation instruction (S 112), and as a response (operation instruction response) to the received operation instruction (command). It is transmitted to the corresponding MFP 10 (the MFP 10 that transmitted the operation instruction) (S113). For example, if the operation instruction is a copy instruction for copying two copies of a document, the contents of the instruction are processed and a two-copy copy execution request (command) is transmitted to the MFP 10 as a response to the received copy instruction. To do.
Upon receiving an operation instruction response (execution request) from the external application 231 by the communication processing unit 121, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124 (S114, S115).

Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation (command processing) requested by the operation instruction response (execution request).
In this process, the MFP 10 sends an MFP activation notification to each external application when the MFP 10 is turned on (powered on). ). Alternatively, when an external application is activated while the power of the MFP 10 is turned on, the external application can specify the MFP 10 and transmit a notification of availability of its own application to the MFP 10.

Next, a second example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications 231 and 232.
FIG. 10 is a diagram illustrating a second example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.

  Each unit of the MFP 10 transmits the MFP activation notification to the external applications 231 and 232 by performing the processing of steps S121 to S124 (same as the processing of steps S101 to S104 described with reference to FIG. 9). In this example, Since the external server 20b equipped with the external application 232 is in a down state due to power-off (may be another cause such as a network failure), it cannot communicate with the external application 232 (a communication error occurs). No app 2 availability notification is sent.

  The application selection unit 122 of the MFP 10 receives only the application 1 availability notification from the external application 231 by the communication processing unit 121 and determines that only the external application 231 can be used from the application identification information added to the notification. Then, by setting the applicability of the corresponding app in the app management table of the app information storage unit 123 to “permitted”, the external app 231 is registered as a usable app (S125, S126).

Thereafter, an operation instruction is input from the operation unit 107 (S127). When the operation instruction is received via the control unit 124, the contents of the application management table in the application information storage unit 123 are referred to and used from the available applications. In the example of FIG. 10, since there is only the external application 231 (1) in the example of FIG. 10, it is selected and information related to the application is stored in the application information storage unit 123 as a use application management table. As a result, the external application 231 (1) is registered as an application. Then, the communication processing unit 121 transmits the received operation instruction to the external application 231 (S128, S129).
The subsequent processes in steps S130 to S133 are the same as the processes in steps S112 to S116 described with reference to FIG.
Note that the MFPs other than the MFP 10 can perform processing similar to the processing described with reference to FIG.

Next, a third example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications 231 and 232.
FIG. 11 is a diagram illustrating a third example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.

Each unit of the MFP 10 transmits the MFP activation notification to the external applications 231 and 232 by performing the processing of steps S141 to S144 (the same as the processing of steps S101 to S104 described with reference to FIG. 9). In this example, Because the external servers 20a and 20b respectively equipped with the external applications 231 and 232 are in a down state due to power-off (may be another cause such as a network failure), the external applications 231 and 232 cannot be communicated. An application availability notification is not sent from any of the external applications 231 and 232.
Therefore, the application selection unit 122 of the MFP 10 does not register the external application 231 or 232 as an available application.

Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S145), the contents of the application management table in the application information storage unit 123 are referred to, but available applications are registered. Therefore, an error response is sent to the control unit 124 as a response to the received operation instruction (S146).
When the control unit 124 receives the error response, the operation shown in FIG. 3 shows an error screen (see FIG. 12, for example) for notifying the user that the function corresponding to the operation instruction input from the operation unit 107 cannot be used. The image is displayed on the unit 107 (actually on the liquid crystal touch panel 51).

Next, a first example of processing for determining available applications by the MFP 10 will be described with reference to FIGS.
FIG. 13 is a diagram illustrating an example of a communication sequence in the MFP 10 when the MFP 10 determines an application that can be used by a user operating a key on the operation unit 107.

The control unit 124 of the MFP 10 registers a plurality of external applications including the external applications 231 (1) and 232 (2) as usable applications by the process described with reference to FIG. When an application selection screen display request is input by the key operation (S151), an available application type information acquisition request (available application type information acquisition request) is sent to the application selection unit 122 (S152).
Upon receiving the acquisition request, the application selection unit 122 acquires (reads) available application type information from the application management table of the application information storage unit 123 (S153), and uses it for the available application type information acquisition request. A response (available application type information acquisition result response) is sent to the control unit 124 (S154).

Upon receiving the available application type information acquisition result response from the application selection unit 122, the control unit 124 displays an application selection screen as shown in FIG. 14 on the operation unit 107 based on the content (S155).
Here, the application selection screen will be briefly described.
On the application selection screen, information indicating the characteristics of the application at a level that can be selected by the user is displayed. In this example, the type of application and the version information are shown, but a screen that can be more easily selected by the user, such as specifically showing the type of function provided in the MFP 10, may be displayed on the operation unit 107 ( It ’s important that what the user can select is displayed).
Information on applications that cannot be used by the MFP 10 is excluded from selection candidates from the beginning.

An unusable situation means that you haven't purchased an option, so the app is not available, or you don't have enough memory to run the app properly Indicates a situation where the application is not allowed to be used.
In this example, an application that can be used can be selected by a key operation (button pressing) on the operation unit 107 by a user or the like, but an application to be used by default may be determined, Instead of designation by key operation on the operation unit 107, the type of application used in the ROM 104, the NVRAM 105, or the HDD 106 of FIG.

Returning to the description of FIG.
After that, by selecting the type of application (here, external application 231 (1), 232 (2)) to be used by the key operation on the application selection screen by the user, the usage instruction for those applications is selected. The data is sent to the unit 122 (S156 , S157 ).
Upon receiving the usage instructions for the external applications 231 (1) and 232 (2), the application selection unit 122 determines the external applications 231 and 232 as usable applications and re-registers them.

Next, a second example of processing for determining an available application by the MFP 10 will be described with reference to FIG.
FIG. 15 is an explanatory diagram for describing a second example of processing for determining an available application by the MFP 10.

  When the application selection unit 122 of the MFP 10 starts the processing described with reference to FIG. 9 at the time of activation (power ON) or at another timing (instruction by key operation on the operation unit 107), the external applications 231 and 232 registered in advance are registered. IP addresses of a plurality of external applications including three (in this example, three external applications) are acquired, and, for example, as shown in FIG. 15A, an application selection screen (application selection screen) including those IP addresses Is displayed on the operation unit 107 by the control unit 124. When an application selection screen is displayed on the operation unit 107 by an instruction by key operation on the operation unit 107, whether the serviceman enters a service code by entering a predetermined password by key operation on the operation unit 107 Alternatively, an application selection screen can be displayed when the administrator of the user inputs a predetermined password by key operation on the operation unit 107 to enter the administrator mode.

Next, by specifying the IP address on the application selection screen (all IP addresses may be specified), the communication processing unit 121 notifies the MFP activation notification to the corresponding external application based on the specified IP address. Send it.
After that, when an app availability notification is received from the external application (multiple external apps) that is the destination of MFP activation notification, the app identification information added to the notification indicates that the external app can be used. Judgment is made, and by setting the applicability of the corresponding app in the app management table of the app information storage unit 123 to “permitted”, the app that can be used is registered.

Then, based on the contents of the application management table in the application information storage unit 123, for example, an application selection screen of any one of patterns 1 to 4 shown in (b) to (e) of FIG. 15 is displayed on the operation unit 107.
Here, each application selection screen will be briefly described.
The application selection screen of pattern 1 shown in (b) of FIG. 15 displays, for example, the types and versions of all external applications on the network 1, and determines (selects) those external applications as usable applications. Can register.

  The application selection screen of pattern 2 shown in FIG. 15C first displays the highest version (latest version) application for each external application of the same type. Those external applications can be switched to another version by pressing the corresponding selection button. The displayed version of the external application can be determined and registered as an available application.

  The application selection screen of pattern 3 shown in (d) of FIG. 15 first displays an application having the best (high) response performance for each external application of the same type. Those external applications can be switched to another response performance by pressing the corresponding selection button. Then, the external application with the displayed response performance can be determined and registered as an available application. A method for measuring response performance (response time) will be described with reference to a communication sequence shown in FIG.

The application selection screen of pattern 4 shown in (e) of FIG. 15 first displays an application having the highest function level (number of functions) for each external application of the same type. These external applications can be switched to another function level by pressing the corresponding selection button. Then, the external application having the displayed function level can be determined and registered as an available application. Since an external application with a high function level is complicated in usage (how to use), it can be determined as an application that can be used depending on the user's purpose.
Note that the application first displayed on the application selection screens of patterns 2 to 4 may be determined as an available application, or may not be determined as an available application.

Next, a third example of processing for determining an available application by the MFP 10 will be described with reference to FIG.
FIG. 16 is an explanatory diagram for describing a third example of a process for determining an available application by the MFP 10.

  The application selection unit 122 of the MFP 10 performs the same processing as described with reference to FIG. 15 by specifying an IP address on the application management screen (see FIG. 16A) displayed on the operation unit 107 (all IPs). An address may be designated), and after the MFP activation notification is transmitted to the corresponding external application based on the designated IP address by the communication processing unit 121, an external application (a plurality of external applications) to which the MFP activation notification is transmitted When the app availability notification is received from the app), it is determined that the external app is available from the app identification information added to the notification, and the correspondence in the app management table of the app information storage unit 123 is determined. Applicable apps are registered by setting the app applicability to “permitted”.

Then, based on the contents of the application management table in the application information storage unit 123, for example, any one of the application management screens of patterns 1 to 4 shown in FIGS. 16B to 16E is displayed on the operation unit 107. Thereafter, an external application to be used is determined (automatically selected) based on a predetermined condition.
Here, an application determination process corresponding to each application management screen will be briefly described.
The application management screen of pattern 1 shown in (b) of FIG. 16 displays an application having the best response performance for each external application of the same type. Therefore, an external application with the response performance can be determined and registered as an available application.

The application management screen of pattern 2 shown in (c) of FIG. 16 displays an application having the highest function level for each external application of the same type. Therefore, it is possible to determine and register an external application of that function level as an available application.
The application management screen of pattern 3 shown in (d) of FIG. 16 displays an application having the lowest function level for each external application of the same type. Therefore, it is possible to determine and register an external application of that function level as an available application.

The application management screen of pattern 4 shown in (e) of FIG. 16 is not actually displayed immediately, but a screen for inputting a login ID and password is displayed first, and the login ID and password are input. When the login ID and password that match them are registered, the application management screen including the type and version of the application pre-assigned to the corresponding user (for example, USER-A), that is, (e The application management screen of pattern 4 shown in FIG. Therefore, the external application on the application management screen can be determined and registered as an available application.
It is also possible to display an application management screen showing the usage frequency for each external application, and determine an external application (for example, the least used one) to be used according to the usage frequency.

According to the first control example, the following effects (1) and (2) can be obtained.
(1) Since the MFP 10 (image processing apparatus) performs an operation using the external application by communicating with the external application, that is, since a common application can be used by a plurality of image processing apparatuses, each image can be used. The processing apparatus can realize a plurality of functions at low cost. In addition, it is possible to reduce the upgrade work of the application. Furthermore, since the operation can be executed using the internal application as it is, the degree of freedom is increased.
(2) Since the MFP 10 registers a plurality of communicable external applications as usable applications and selects the external application to be used from among them, even when the server storing the external application is down for some reason, It is possible to operate using an external application, and to prevent the MFP from being disabled.

[Second control example]
Next, a first example of a communication sequence between an external application and the MFP 10 when the external application is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications 231 and 232. Further, it is assumed that there are only two MFPs 10. However, the two units here are MFPs 10a (1) and 10b (2).
FIG. 17 is a diagram illustrating a first example of a communication sequence between an external application and the MFP 10 when the external application is activated. In this case, it is assumed that the types of applications that can be used in accordance with the model of the MFP 10 are stored in advance in the ROM 104, the NVRAM 105, or the HDD 106 (see FIG. 2) of the MFPs 10a and 10b.

When the external application 231 (1) starts up (when the external server 20a is powered on), the external application 231 (1) transmits an application availability notification including its identification information (application 1 availability notification) to the MFP 10a (1) (S161). ).
The external application 232 (2) also sends an application availability notification (application 2 availability notification) including its own identification information to the MFP 10b (2) when it starts up (when the external server 20b is powered on) (S162). ).

When the application processing unit 121 receives an application 1 availability notification from the external application 231 (1) by the communication processing unit 121, the application selection unit 122 of the MFP 10a (1) can use the external application 231 from the application identification information added to the notification. In step S163, the external application 231 is registered as an available application by setting the availability of the corresponding application in the application management table of the application information storage unit 123 to “available”.
Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124, the contents of the application management table in the application information storage unit 123 are referred to, and the external application 231 (1) that is an available application is used. The communication processing unit 121 transmits the received operation instruction (S165).

When the application selection unit 122 of the MFP 10b (2) receives the application 2 availability notification from the external application 232 (2) by the communication processing unit 121, the external application 232 can be used from the application identification information added to the notification. In step S164, the external application 232 is registered as an app that can be used by setting the applicability of the corresponding app in the app management table of the app information storage unit 123 to “permitted”.
Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124, the external application 232 (2), which is an available application, is referred to by referring to the content of the application management table in the application information storage unit 123. The communication processing unit 121 transmits the received operation instruction (S166).

According to the second control example, the same effect as the above (1) can be obtained.
In addition, since an external application to be used is determined for each MFP model, an optimum operation can be performed for each MFP model.

[Third control example]
Next, a fourth example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there is only one external application 232 (2). Further, it is assumed that there is an internal application 131 (3) indicated by a broken line in FIG.
FIG. 18 is a diagram illustrating a fourth example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.

  The application selection unit 122 of the MFP 10 is indicated by information stored in the application management table of the external application 232 and the internal application 131 (the application information storage unit 123 in FIG. 6) registered in advance at the time of activation (power ON). Issue a startup notification (MFP startup notification). That is, the communication processing unit 121 causes the MFP activation notification to be transmitted to the external application 232 (2) (S171, S172). In addition, an MFP activation notification is sent to the internal application 131 (3) (S173).

When the internal application 131 (3) receives the MFP activation notification from the application selection unit 122, the internal application 131 (3) sends an application availability notification (application 3 availability notification) including its own identification information as a response to the notification to the application selection unit 122 ( S174).
Upon receipt of the app 3 availability notification from the internal app 131, the app selection unit 122 determines that the internal app 131 is available from the app identification information added to the notification, and the app selection unit 122 stores the app management table 123 in the app management table 123. By setting the applicability of the corresponding app as “permitted”, the internal app 131 (3) is registered as a usable app.

When the external server 20b on which the external application 232 is installed is activated, the external application 232 receives an MFP activation notification from the MFP 10 and receives an application availability notification (application 2) including its own identification information as a response to the notification. (Availability notification) is transmitted to the corresponding MFP 10 (S175).
When the communication processing unit 121 receives an application 2 availability notification from the external application 232, the application selection unit 122 of the MFP 10 determines that the external application 232 is available from the application identification information added to the notification, and the application information By setting the applicability of the corresponding app in the app management table of the storage unit 123 to “permitted”, the external app 232 (2) is registered as a usable app (S176).

Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S177), the contents of the application management table in the application information storage unit 123 are referred to and used from the available applications. By selecting (determining) the application to be used (in this case, the internal application 131 (3)), and storing information on the application to be used in the application information storage unit 123 as a use application management table, the internal application 131 (3) Register as an app that uses. Then, the received operation instruction is sent to the internal application 131 (S178).
Here, when there are a plurality of application candidates, the application selection unit 122 sets the application use priority as the internal application priority or the external application priority in advance, or sets the application type priority, The application to be used can be selected according to the priority. Of course, selection can also be made by an instruction by key operation on the operation unit 107.

When the internal application 131 (3) receives the operation instruction from the application selection unit 122, the internal application 131 (3) processes the content of the operation instruction (S179), and as a response (operation instruction response) to the operation instruction received the corresponding operation execution request. The data is sent to the application selection unit 122 (S180).
Upon receiving the operation instruction response (execution request) from the internal application 131, the application selection unit 122 sends the operation instruction response to the control unit 124 (S181).
Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation requested by the operation instruction response (execution request).

  In this process, the MFP 10 sends an MFP activation notification to the external application and the internal application when the power of the MFP 10 is turned on, but the notification is performed at another timing (for example, an instruction by key operation on the operation unit 107). May be.

According to the third control example, the same effect as the above (1) can be obtained.
In addition, since the MFP 10 registers not only a communicable external app but also an internal app as an app that can be used and selects an external app to be used from among them, the server storing the external app is down for some reason However, it is possible to operate using other external applications or internal applications, and it is possible to reliably prevent the MFP from being disabled.

[Fourth control example]
Next, a fifth example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there is only one external application 232 as the external application. Further, it is assumed that there is an internal application 131 (3) indicated by a broken line in FIG.
FIG. 19 is a diagram illustrating a fifth example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.

  Each unit of the MFP 10 performs the processing of steps S191 to S194 (same as the processing of steps S171 to S174 described with reference to FIG. 18), thereby sending an MFP activation notification to the external application 232 (1) and the internal application 131 (3). However, in this example, the external server 20b on which the external application 232 is mounted cannot communicate with the external application 232 because the external server 20b is in a down state due to power-off (may be another cause such as a network failure). From 232, the app 2 availability notification is not sent.

Upon receipt of the app 3 availability notification from the internal app 131, the app selection unit 122 determines that the internal app 131 is available from the app identification information added to the notification, and the app selection unit 122 stores the app management table 123 in the app management table 123. By setting the applicability of the corresponding app as “permitted”, the internal app 131 (3) is registered as a usable app.
After that, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S195), the contents of the application management table in the application information storage unit 123 are referred to. Therefore, the internal application 131 (3) is selected as an application that uses the internal application 131 (3), and information about the application to be used is stored in the application information storage unit 123 as a use application management table. Register as an app to use. Then, the received operation instruction is sent to the internal application 131 (S196).

When receiving the operation instruction from the application selection unit 122, the internal application 131 (3) processes the content of the operation instruction (S197), and as a response (operation instruction response) to the operation instruction having received the corresponding operation execution request. The data is sent to the application selection unit 122 (S198).
Upon receiving the operation instruction response from the internal application 131, the application selection unit 122 sends the operation instruction response to the control unit 124 (S199).
Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation requested by the operation instruction response (execution request).

Thereafter, when the external application 232 is activated by turning on the power of the external server 20b on which the external application 232 is mounted, the external application 232 transmits an application availability notification including its own identification information (application 2 availability notification) to the MFP 10 (S200).
When the communication processing unit 121 receives an application 2 availability notification from the external application 232, the application selection unit 122 of the MFP 10 determines that the external application 232 is available from the application identification information added to the notification, and the application information The app management table is updated by setting the applicability of applicability in the app management table of the storage unit 123 to “approve”, and the external app 232 (2) is also registered as an app that can be used (S201).

  Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S202), the contents of the application management table in the application information storage unit 123 are referred to and used from the available applications. Select the app you want to Here, it is assumed that the application use priority is set in advance as an external application priority. Accordingly, by selecting the external application 232 (2) as an application to be used and storing information on the application to be used in the application information storage unit 123 as a use application management table, the application using the external application 232 (2) is selected. sign up. And it is made to transmit to the external application 232 by the communication processing part 121 (S203, S204).

When the external application 231 receives the operation instruction from the MFP 10, the external application 231 processes the content of the operation instruction (S 205), and responds to the received operation instruction (command) as a response (operation instruction response) to the corresponding MFP 10. (S206).
When the communication processing unit 121 receives the operation instruction response from the external application 231, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124 (S 207 and S 208).

When receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation requested by the operation instruction response.
In this process, the MFP 10 sends an MFP activation notification to the external application and the internal application when the power of the MFP 10 is turned on, but the notification is performed at another timing (for example, an instruction by key operation on the operation unit 107). May be.

According to the fourth control example, the same effect as in the third control example can be obtained.
Further, when the number of external applications that can be communicated on the way increases, the MFP 10 additionally registers the external applications as usable applications. Therefore, when the usage priority of the additionally registered external applications is high, the external applications are used. Therefore, the usability for the user is improved.

[Fifth control example]
Next, a sixth example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is activated will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 20 is a diagram illustrating a sixth example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated.
Each unit of the MFP 10 transmits the MFP activation notification to the external applications 231 and 232 by performing the processes of steps S211 to S214 (same as the processes of steps S101 to S104 described with reference to FIG. 9).

When the external server 20a on which the external application 231 is installed is activated, the external application 231 receives the MFP activation notification from the MFP 10 and indicates a function provided by itself including the identification information of itself as a response to the notification. Information (application 1 function information notification) is transmitted to the corresponding MFP 10 (S215).
When the external server 20b on which the external application 232 is installed is activated, when the external application 232 receives the MFP activation notification from the MFP 10, the external application 232 includes the identification information of its own application as a response to the notification. Information indicating the (realizable) function (application 2 function information notification) is transmitted to the corresponding MFP 10 (S217).

  When the communication processing unit 121 receives an application 1 function information notification from the external application 231 and an application 2 function information notification from the external application 232, the application selection unit 122 of the MFP 10 receives application identification information added to the notifications. Are determined that the external applications 231 and 232 can be used, the functions of the external applications 231 and 232 are determined, and the external applications 231 and 232 are included in the application management table of the application information storage unit 123, respectively. By storing information indicating functions, the functions are registered (S216, S218).

Thereafter, when the administrator login ID and password are input by a key operation on the operation unit 107 by the user's administrator, and the login ID and password that match them are registered, the control unit 124 Special mode, and a request for an administrator function is sent to the application selection unit 122 (S219).
Upon receiving a request for the administrator function from the control unit 124, the application selection unit 122 selects an application having an administrator function (here, external application 231 (1)) as an application to be used, By storing information on the application to be used in the application information storage unit 123 as a use application management table, the application is registered as an application that uses the external application 231 (1). Then, the external processing unit 231 causes the communication processing unit 121 to transmit an operation instruction corresponding to the manager function (S220, S221).

When the external application 231 receives the operation instruction corresponding to the administrator function from the MFP 10, the external application 231 processes the content of the operation instruction (S 222), and responds to the operation instruction received the corresponding operation execution request (operation instruction response). To the corresponding MFP 10 (S223).
When the communication processing unit 121 receives the operation instruction response from the external application 231, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124 (S 224 and S 225).
Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes an operation corresponding to the administrator function requested by the operation instruction response (execution request).

In addition, when the login ID and password for a general user are input by a key operation on the operation unit 107 by a general user, and the login ID and password that match those are registered, the control unit 124 The standard mode is entered, and a request for a general user function is sent to the application selection unit 122 (S226).
When receiving the request for the general user function from the control unit 124, the application selection unit 122 selects the application having the general user function (here, the external application 232 (2)) as an application to be used, By storing information about the application to be used in the application information storage unit 123 as a use application management table, the application is registered as an application that uses the external application 232 (2). Then, the communication processing unit 121 transmits an operation instruction corresponding to the general user function to the external application 232 (S227, S228).

When the external application 232 receives an operation instruction corresponding to the general user function from the MFP 10, the external application 232 processes the content of the operation instruction (S 229), and responds to the operation instruction received the corresponding operation execution request (operation instruction response). To the corresponding MFP 10 (S230).
When the communication processing unit 121 receives the operation instruction response from the external application 231, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124 (S 231 and S 232).

Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes an operation corresponding to the general user function requested by the operation instruction response (execution request).
In this process, the MFP 10 transmits an MFP activation notification to each external application when the power of the MFP 10 is turned on. However, the notification is performed at another timing (for example, an instruction by key operation on the operation unit 107). Also good.

According to the fifth control example, the same effect as the above (1) can be obtained.
In addition, the MFP 10 registers a communicable external app as a usable app, and switches the selection of the external app to be used for each administrator and general user from among them. It can be done and the usability for administrators and general users is improved.

  In the fifth control example, the application selection unit 122 of the MFP 10 includes an external application having an administrator function (administrator function) and a general user function (general function) shown in FIG. Each external application is notified of information indicating these functions, and those functions are registered. However, the normal copy function, reserved copy function, and interrupt copy function shown in FIG. In addition, each external application, each external application provided with a copy function, a printer function, a scanner function, and a fax (FAX) function shown in (c) of the figure, or a high security function shown in (d) of the figure, Have each external application equipped with standard security compatible functions and low security compatible functions be notified of information indicating those functions, and register those functions. Rukoto can also.

[Sixth control example]
Next, a seventh example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 when the MFP 10 is started up (an example in which the MFP performs an operation using an application with the best response performance) ) Will be described with reference to FIG. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 23 is a diagram illustrating a seventh example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 is activated. In this case, it is assumed that the MFP 10 has a function as an application response time measuring unit 125 in the controller 11 as shown in FIG. The application response time measuring unit 125 measures time after transmitting an MFP activation notification to each external application including the external applications 231 and 232.

  The application selection unit 122 of the MFP 10 is registered in advance with external applications 231 and 232 (indicated by information stored in the application management table of the application information storage unit 123 in FIG. 22) at the time of activation (power ON). Issue an activation notification (MFP activation notification). That is, the MFP activation notification is sequentially transmitted to the external applications 231 (1) and 232 (2) by the communication processing unit 121 via the application response time measuring unit 125 (S251 to S256). An application identification number for identifying the external application 231 or 232 is added to the MFP activation notification to the external application 231 or 232, respectively, which is acquired from the application information storage unit 123 of FIG.

The application response time measuring unit 125 measures the response time Ta when receiving an MFP activation notification for the external application 231 (1) from the application selecting unit 122, and the response time when receiving the MFP activation notification for the external application 232 (2). Each measurement of Tb is started.
When the external server 20a on which the external application 231 is installed is activated, the external application 231 receives an MFP activation notification from the MFP 10 and receives an application availability notification (application 1) including its own identification information as a response to the notification. (Availability notification) is transmitted to the corresponding MFP 10 (S257).
When the external application 232 also receives the MFP activation notification from the MFP 10 when the external server 20b on which the external application 232 is installed is activated, an application availability notification including identification information of its own application as a response to the notification ( Application 2 availability notification) is transmitted to the corresponding MFP 10 (S260).

When the communication processing unit 121 receives the application 1 availability notification from the external application 231 and the application 2 availability notification from the external application 232, the application selection unit 122 of the MFP 10 receives the notification via the application response time measurement unit 125. It is determined whether or not the external applications 231 and 232 can be used from the application identification information added to these notifications, and “permitted” indicates whether or not the corresponding application can be used in the application management table of the application information storage unit 123. As a result, the external applications 231 and 232 are registered as usable applications (S257 to S262).
The application response time measurement unit 125 measures the response time Ta when receiving the app 1 availability notification from the external application 231 (1), and responds when receiving the app 2 availability notification from the external application 232 (2). Each measurement of time Tb is stopped.

  After that, when the operation instruction is input from the operation unit 107 and received via the control unit 124 (S263), the application selection unit 122 receives the content of the application management table in the application information storage unit 123 and the application response time measurement unit 125. The application to be used is selected from the available applications with reference to the response times Ta and Tb measured by. For example, when the relationship between Tb and Ta is Tb <Ta, it is determined that the external application 231 (1) has better response performance, and is preferred as an application that uses the external application 231 (1). Select

  When the internal application 131 or 132 indicated by the broken line in FIG. 22 is installed, it is not necessary to measure the response time, and the use of the internal application guarantees high performance. Can also be preferentially selected as the app to be. Further, it can be combined with function selection, and when there are a plurality of applications having the same function, it can be selected as an application using an application having the best response performance (response time is short).

  After selecting the application that uses the external application 231 (1) as the application selection unit 122, the application selection unit 122 stores information on the application to be used in the application information storage unit 123 as a use application management table, whereby the external application 231 (1). Register as an app that uses. Then, the external application 231 is caused to transmit the received operation instruction by the communication processing unit 121 via the application response time measuring unit 125 (S264 to S266).

When the external application 231 receives the operation instruction from the MFP 10, the external application 231 processes the content of the operation instruction (S 267), and the MFP 10 corresponding as a response (operation instruction response) to the received operation instruction (command). (S268).
The application selection unit 122 of the MFP 10 receives the operation instruction response (execution request) from the external application 231 by the communication processing unit 121, and when receiving the operation instruction response via the application response time measurement unit 125, sends the operation instruction response to the control unit 124. (S269 to S271).

Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation (command processing) requested by the operation instruction response (execution request).
In this process, the MFP sends an MFP activation notification to each external application when the MFP is turned on. However, the notification may be performed at another timing (for example, an instruction by key operation on the operation unit). Good.

In addition, the time measurement by the application response time measurement unit (response time of the external application) may be performed not only when the power is turned on (when the MFP is activated) but also when the MFP job is stopped (job execution). Do not do it). Alternatively, it may be performed at a timing when a new external application is added.
Further, each MFP 10 in the first embodiment may be connected to an external application not only via a network but also via another interface such as a USB / I / F or IEEE1394 / I / F so as to use the external application. it can.

As electronic devices having a communication function, and a plurality of external servers 20 (20a, 20b,. ) And an application management server (application management server) 30, which can be communicably connected via a network 1 such as a LAN. For example, the MFP 10 and the external server 20 can communicate with each other in a one-to-many relationship via the network 1, but the MFP 10 and the external server 20 can be connected to the external device by connecting the MFP 10 and the external server 20 via a communication line such as USB or IEEE1394. It is also possible for the server 20 to communicate in a one-to-one relationship.

Note that the hardware configuration of the MFP 10, the external server 20, and the application management server 30 and the operation screen on the operation unit of the MFP 10 are the same as those described with reference to FIGS. 2 to 5 and FIG. To do. Since the hardware configuration of the application management server 30 is the same as that obtained by deleting the operation unit, USB • I / F, and IEEE1394 • I / F from the external server 20, illustration and description thereof are also omitted.

FIG. 26 is a block diagram illustrating a main functional configuration example of the application management server 30 of FIG.
The application management server 30 has functions as a communication processing unit 301, an application information storage unit 302, and a control unit 303.
The communication processing unit 301 communicates with or directly connects to the external applications 231 and 232 and the MFP 10 that are respectively installed in a plurality of external servers 20 (20a, 20b,...) On the network 1. Communication means for communicating with the external device.

  The application information storage unit 302 is a location (IP address) of an available external application, that is, an installation location of the external server 20 on which an available external application is installed, an available external application type, an available external application Various types of information for managing external applications such as information indicating operations (functions) that can be executed by the application are stored as an application management table. Thereby, an external application that can be used in each MFP 10 can be registered. The application information storage unit 302 exists on the SDRAM, NVRAM, or HDD, and is updated whenever information changes. Therefore, the application information storage unit 302 functions as an application management unit.

  The application information storage unit 302, when an application (internal application) is also installed in the MFP 10, the location (IP address) of the internal application, that is, the installation location of the MFP 10 in which the internal application is installed, Various types of information for managing the internal application, such as information indicating the type of internal application and operations that can be executed by the internal application, can also be stored as the application management table.

The control unit 303 comprehensively controls each unit including the communication processing unit 301 and the application information storage unit 302, and functions as a control unit.
Therefore, the control unit 303 and the communication processing unit 301 function as an application information transmission unit.

Next, control (processing) according to the present invention in the image forming system of the second embodiment configured as described above will be specifically described with reference to FIGS.
[Seventh control example]
First, referring to FIG. 27, a first example (basic) of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 and the application management server 30 when the MFP 10 is turned on and when an operation instruction is given. I will explain. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 27 is a diagram illustrating a first example of a communication sequence between the MFP 10, the external application, and the application management server 30 when the MFP 10 is powered on and when an operation instruction is given.

When the external application 231 (1) is activated by turning on the power of the external server 20a on which the external application 231 (1) is mounted, an application availability notification (application 1 availability notification) including its own identification information and type information is sent to the application management server 30. Transmit (S301).
When the external application 232 is also activated by turning on the power of the external server 20b on which the external application 232 is mounted, the external application 232 transmits an application availability notification (application 2 availability notification) including its own identification information and type information to the application management server 30. (S303).

  When the communication processing unit 301 receives the application 1 availability notification from the external application 231 (1), the control unit 303 of the application management server 30 determines that the external application 231 is based on the application identification information and type information added to the notification. It is determined that the application can be used, the type of the external application 231 is determined, the name (application name), type, and IP address of the external application 231 are associated with each other and stored in the application management table of the application information storage unit 302 to manage the application. By updating the table, the external application 231 is registered as an available application (S302).

  When the communication processing unit 301 receives the app 2 availability notification from the external app 232 (2), the communication processing unit 301 determines that the external app 232 is available from the app identification information and type information added to the notification, and The type of the application 232 is determined, the name, type, and IP address of the external application 232 are associated with each other, stored in the application management table of the application information storage unit 302, and the application management table is updated to use the external application 232 It registers as a possible application (S304).

Here, the application management table, MFP management table, and MFP-application association table stored in the application information storage unit 302 of the application management server 30 will be described with reference to Tables 3 to 5.
As shown in Table 3, the application management table indicates the application name, the IP address (application location information) where the application exists, and the type of application for each application (external applications 231, 232,...) On the network 1. I remember information. In this example, four external applications are registered.

  Note that app-1 (having a copy function, printer function, and scanner function) has a first external application 231, and app-2 (having a copy function, a printer function) has a second external application 232. , App-3 (having a copy function, printer function, and scanner function) indicates a third external app, and app-4 (having a scanner function) indicates a fourth external app. To do. Each of these applications may be provided with a plurality of types of functions as described with reference to FIG.

As shown in Table 4, the MFP management table stores the MFP name and MFP IP address (MFP location information) for each MFP 10 on the network 1. In this example, four MFPs 10 are registered.
Table 5 is an MFP-application association table, which shows external applications that are currently available to each MFP 10.
Each external application may have a plurality of functions.

Returning to the description of FIG.
The application selection unit 122 of the MFP 10 sends a search request (available application search request) to the application management server 30 by the communication processing unit 121 in order to inquire the application management server 30 about available applications when the power is turned on (power-on). Transmit (S305, S306).
When the communication processing unit 301 receives an available application search request from the MFP 10 via the communication processing unit 301, the control unit 303 of the application management server 30 refers to the application management table in the application information storage unit 302 and can use an external application that can be used from the application management table. The type of the external application 231 or 232 that is an application and the application location information (IP address) where the external application 231 or 232 exists are read (S307), and a response to the available application search request received (search result response) To the corresponding MFP 10 (S308).

  When the communication processing unit 121 receives the search result response from the application management server 30, the application selection unit 122 of the MFP 10 includes the types of external applications 231 and 232 that are external applications that can be used based on the search result response. The available external applications 231 and 232 are registered by storing them as a table as shown in Table 1, for example, together with the IP address indicating the (presence) location (S309, S310).

  Thereafter, when an operation instruction is input from the operation unit 107 and received via the control unit 124 (S311), an application (in this case, an external application) that can be used from among the applications that can be processed with reference to the contents of the previously registered table. Application 231 (1)) is selected, and information about the application to be used is stored as a table, thereby registering the application as the application using the external application 231 (1). Then, the communication processing unit 121 transmits the received operation instruction to the external application 231 (S312 and S313).

Subsequent processes in steps S314 to S317 are almost the same as the processes in steps S112 to S116 described with reference to FIG.
In this process, when the external application is activated while the power of the MFP 10 is ON, the external application transmits a notification of availability of its own application to the application management server 30. However, the application management server 30 After the power is turned on, the MFP 10 and the external server 20 on the network 1 on which the application is installed are periodically visited to check whether the application can be used, and the application information storage unit according to the confirmation result The application management table stored in 302 can be updated.

Next, a second example of a communication sequence between the MFP 10 and an external application, which is an application in the external server 20, and the application management server 30 when the MFP 10 is turned on and when an operation instruction is given will be described with reference to FIG. To do. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 28 is a diagram illustrating a second example of a communication sequence between the MFP 10, the external application, and the application management server 30 when the MFP 10 is turned on and when an operation instruction is given.

When the power is turned on, the application selection unit 122 of the MFP 10 causes the communication processing unit 121 to transmit a search request (available application search request) to the application management server 30 in order to make an inquiry about available applications to the application management server 30 (S321). , S322).
When the communication processing unit 301 receives an available application search request from the MFP 10 by the communication processing unit 301, the control unit 303 of the application management server 30 refers to the application management table in the application information storage unit 302, but the available external application is registered. Therefore, it transmits to the corresponding MFP 10 as a response (search result response) to the available application search request received that there is no external application available (S323).

When the communication processing unit 121 receives the search result response from the application management server 30 from the application management server 30, the application selection unit 122 of the MFP 10 determines that there is no external application that can be used from the search result response. No external application is registered (S324).
Therefore, after that, even if an operation instruction is input from the operation unit 107 and received via the control unit 124 (S325), since an available application is not registered, an error response is returned as a response to the received operation instruction. The data is sent to the control unit 124 (S326).
Upon receiving the error response, the control unit 124 displays an error screen on the operation unit 107 shown in FIG. 3 to inform the user that the function corresponding to the operation instruction input from the operation unit 107 cannot be used. .

Even in the seventh control example, the application selection unit 122 of the MFP 10 can perform any one of the processes described in FIGS. 13 to 16 (a process for determining an available application).
However, when the processing described with reference to FIGS. 13 and 14 is performed, the search result response from the application management server 30 is received by the communication processing unit 121 and an available external application is registered. When an application selection screen display request is input by the above key operation, an acquisition request (available application type information acquisition request) for available application type information (type information) is sent to the application selection unit 122.

When the processing described with reference to FIG. 15 is performed, the search result response from the application management server 30 is received by the communication processing unit 121 and an available external application is registered. The application selection screen of any one of patterns 1 to 4 shown in (b) to (e) is displayed on the operation unit 107.
When the processing described with reference to FIG. 16 is performed, a search result response from the application management server 30 is received by the communication processing unit 121 and an available external application is registered. The application management screen of any one of patterns 1 to 4 shown in (b) to (e) is displayed on the operation unit 107.

Each MFP 10 is provided with an application response time measurement unit (same as the application response time measurement unit 125 in FIG. 22), and the application management server 30 transmits an application response time acquisition request to each MFP 10 to perform the following processing. By performing the acquisition and acquiring the application response time as a response to the request, it is possible to know the response performance of each external application.
When the application selection unit 122 of each MFP 10 receives an application response time acquisition request from the application management server 30 by the communication processing unit 121, the communication processing unit 121 sends a notification to the external application and then responds to the notification. Time measurement until reception by the communication processing unit 121 is performed for each application, and the measurement time for each application (response time for each application) is transmitted to the application management server 30 as a response to the application response time acquisition request.

Also according to the seventh control example, the effects as shown in the above (1) and (2) can be obtained.
In addition, since the application management server 30 registers all external applications available on the network, the external applications can be managed collectively. This makes it easier to deal with network failures. Also, workarounds can be concentrated in one place.
Further, the MFP 10 transmits a search request for available applications to the application management server 30, and the application management server 30 that has received the search request sends a response (search result response) to the search request in the application information storage unit 302. The MFP 10 that has transmitted to the corresponding MFP 10 based on the contents of the application management table and received the search result response registers the contents of the response (available applications), and selects an external application to be used from among them. Even when a server in which any external application is stored goes down for some reason, it is possible to operate using another external application, and it is possible to prevent the MFP from being disabled.

[Eighth control example]
Next, a first example of a communication sequence between the MFP 10 and an external application that is an application in the external server 20 at the time of an MFP registration instruction in the MFP 10 will be described with reference to FIG.
FIG. 29 is a diagram showing an example of a communication sequence between the MFP 10 and the application management server 30 at the time of MFP registration instruction in the MFP 10.

  Similar to the processing described with reference to FIG. 27, the control unit 303 of the application management server 30 uses the application corresponding to all external applications including the external application 231 (1) that can communicate on the network 1 by the communication processing unit 301. Each time the notifications are received, the available external application and its type are determined from the application identification information and the type information added to the notification, and the name (application name), type, and IP address of the external application are determined. All the external applications available on the network 1 are registered by associating them with each other and storing them in the application management table of the application information storage unit 302 and updating the application management table. At this time, based on a predetermined condition, for example, as shown in any of the following (a) to (e), allocation of an external application that can be used for each MFP 10 is performed. That is, each MFP 10 determines (selects) an external application that can be used.

(A) Corresponding apps that can be used to the MFP 10 with a regular contract.
(B) In order to distribute the load, an application to be used is assigned according to the usage frequency of each external application. For example, an external application that is not used is preferentially assigned as an available application.

(C) An external application with the best response performance is preferentially assigned to each MFP 10 as an available application. In this case, each MFP 10 is provided with an application response time measurement unit, and the application management server 30 transmits an application response time acquisition request to each MFP 10 and acquires the application response time as a response to the request, whereby each external application You can know the response performance. The processing on each MFP 10 side is as described in the seventh control example.

(D) Applicable applications are assigned according to the type of MFP 10 (for example, a high speed machine or a low speed machine). For example, the application with the highest function (high-speed operation application) is assigned to the MFP 10 of the high-speed machine, and the application with the lowest function (low-speed operation application) is assigned to the MFP 10 of the low-speed machine.
(E) Assign available applications according to the memory installed in the MFP 10 (determined for each MFP model).
Each external application may have a plurality of functions.

On the other hand, when an MFP registration instruction is input from the operation unit 107, the control unit 124 of any of the MFPs 10 causes the communication processing unit 121 to transmit the MFP registration instruction to the application management server 30 as illustrated in FIG. (S331, S332).
When the communication processing unit 301 receives an MFP registration instruction from any MFP 10 on the network 1, the control unit 303 of the application management server 30 indicates an application information storage unit 302 to indicate an application to be used by the MFP 10. The application management table reads the type of the application (for example, external application 231) used by the corresponding MFP 10 and the application location information (IP address) where the application exists (S333), and receives the response to the MFP registration instruction (use) (Application instruction) is transmitted to the corresponding MFP 10 (S334).

When the communication processing unit 121 receives a use application instruction from the application management server 30, the application selection unit 122 of the MFP 10 stores the type of external application used based on the use application instruction together with an IP address indicating the installation location. Thus, the external application to be used is registered (S335, S336).
Thereafter, although illustration is omitted, when an operation instruction is input from the operation unit 107 and received via the control unit 124, the communication processing unit 121 transmits the operation instruction to the previously registered external application (application to be used). Send it.

When the external application 231 receives an operation instruction from any of the MFPs 10, the external application 231 processes the contents of the operation instruction and transmits a corresponding operation execution request to the corresponding MFP 10 as a response to the operation instruction received (operation instruction response). .
When the communication processing unit 121 receives the operation instruction response from the external application 231, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124.
The control unit 124 executes the operation requested by the operation instruction response received from the application selection unit 122.

Also according to the eighth control example, the effects as shown in the above (1) and (2) can be obtained.
In addition, since the application management server 30 registers all external applications available on the network, the external applications can be managed collectively. This makes it easier to deal with network failures. Also, workarounds can be concentrated in one place.
Further, the application management server 30 selects an application used by the MFP 10 from the available external applications, transmits information on the selected application to the MFP 10, and the MFP 10 that has received the information based on the information Since the application to be used is registered, even if the server that stores one of the external applications goes down for some reason, it can operate using other external applications and avoids the MFP being unusable. it can.

  Also in the second embodiment, when the controller 11 of the MFP 10 is equipped with the internal application 131 or 132 indicated by the broken line in FIG. 25, it is selected as an application that uses the internal application and an operation instruction is transmitted to the internal application. It is also possible to perform the same process as the process for an external application.

[Third embodiment]
Next, an image forming system which is a third embodiment of the electronic apparatus system according to the present invention will be described. A network connection example of the image forming system is the same as that shown in FIG.
First, a main functional configuration example of the MFP 10 and the external server 20 will be specifically described with reference to FIG.
30 is a block diagram showing still another example of main functional configurations of the MFP 10 and the external server 20a in FIG. 1. The same parts as those in FIG. 6 and FIG. Omitted.

The controller 11 of the MFP 10 has functions as a communication processing unit 121, an application selection unit 122, an application information storage unit 123, a control unit 124, and an authentication processing unit 127. The CPU 101 in FIG. 2 operates according to the program in the ROM 104, and selects the SDRAM 103, NVRAM 105, HDD 106, MAC / I / F 111, USB / I / F 109, IEEE 1394 / I / F 110 in FIG. 2 as necessary. It can be realized by using it.
In addition to the processing described with reference to FIG. 6, the application selection unit 122 transmits and receives authentication information to and from the authentication processing unit 127.
The authentication processing unit 127 performs an authentication process described later.

The external server 20a has functions as an application communication processing unit 241, an application control unit 242, a device information storage unit 243, and an application authentication unit 244. These functions are realized by the CPU 201 shown in FIG. 7 operating according to the external application 231 stored in the ROM 104 and using the MAC / I / F 211, USB / I / F 209, IEEE 1394 / I / F 210 as necessary. It can be done.
The application authentication unit 244 performs an authentication process described later.
The main functional configuration of the other external server 20b is substantially the same as that of the external server 20a.

Next, the control according to the present invention in the image forming system according to the third embodiment configured as described above, that is, the communication sequence between the MFP 10 and the external application that is the application in the external server 20 when the MFP is activated. A first example will be described with reference to FIGS. 31 and 32. FIG. For convenience of explanation, it is assumed that there are only two external applications, external applications 231 and 232.
FIG. 31 is a diagram showing a first example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 in FIG. 30 is activated.
32 is a diagram showing a second example of a communication sequence between the MFP 10 and the external applications 231 and 232 when the MFP 10 in FIGS. 32 and 30 is activated. FIG.

  The application selection unit 122 of the MFP 10 is registered in advance with external applications 231 and 232 (indicated by information stored in the application management table of the application information storage unit 123 in FIG. 30) when activated (powered on). Issue an activation notification (MFP activation notification). That is, the communication processing unit 121 sequentially transmits MFP activation notifications to the external applications 231 (1) and 232 (2) (S101 to S104). An application identification number for identifying the external application 231 or 232 is added to the MFP activation notification for the external application 231 or 232, respectively, which is acquired from the application information storage unit 123 of FIG.

When the external server 20a on which the external application 231 is installed is activated, the external application 231 receives the MFP activation notification from any of the MFPs 10, and as a response to the notification, the external application 231 has its own identification information and specific authentication information ( An application availability notification (application 1 availability notification) including key information used for encryption is transmitted to the corresponding MFP 10 (the MFP 10 that transmitted the MFP activation notification) (S105).
When the external application 232 also receives the MFP activation notification from the MFP 10 when the external server 20b on which the external application 232 is installed is activated, the external application 232 includes identification information of its own application and specific authentication information as a response to the notification. An application availability notification (application 2 availability notification) is transmitted to the MFP 10 (S107).

When the communication processing unit 121 receives the application 1 availability notification from the external application 231 and the application 2 availability notification from the external application 232 by the communication processing unit 121, the application selection unit 122 of the MFP 10 receives the application identification information added to the notifications. Thus, it can be determined whether or not the external applications 231 and 232 can be used. In this processing example, since both of the external applications 231 and 232 can be used, the external application 231 is set to “permitted” by setting “permitted” for the corresponding application use in the application management table of the application information storage unit 123. , 232 are registered as available applications (S106, S108). At this time, since authentication information added to the received app 1 availability notification and app 2 availability notification is stored together, the authentication processing unit together with the identification information of the corresponding external applications 231 and 232 is stored. 127 (S401, S402).
When the authentication processing unit 127 receives each authentication information from the application selection unit 122 together with the identification information of the corresponding external application 231, 232, the authentication processing unit 127 associates each authentication information with the identification information of the corresponding external application 231, 232. Remember.

  After that, when the operation instruction is input from the operation unit 107 and received via the control unit 124 (S411), the application selection unit 122 can use the application by referring to the content of the application management table in the application information storage unit 123. An application to be used (used) (in this case, external application 231 (1)) is selected (determined) from among the various applications, and information relating to the application to be used is stored in the application information storage unit 123 as a used application management table. As a result, the external application 231 (1) is registered as an application. Subsequently, an authentication information acquisition request corresponding to the external application 231 is sent to the authentication processing unit 127 together with the identification information of the external application 231 (S412).

Upon receiving the authentication information acquisition request from the application selection unit 122 together with the identification information of the external application 231, the authentication processing unit 127 sends the authentication information stored in association with the identification information to the application selection unit 122.
Upon receiving the authentication information from the authentication processing unit 127, the application selection unit 122 adds the authentication information to the previously received operation instruction and causes the communication processing unit 121 to transmit the authentication information (S414, S415).

  When the external application 231 receives an operation instruction from any of the MFPs 10, the external application 231 performs an authentication process for confirming the validity of the operation instruction. That is, the application authentication unit 244 analyzes the authentication information added to the operation instruction, and determines whether or not it matches the authentication information sent in advance to the MFP 10 that has transmitted the operation instruction. When the authentication is successful, that is, when the authentication information added to the received operation instruction matches the authentication information sent in advance to the MFP 10 that is the source of the operation instruction, the contents of the operation instruction are processed. (S416) The corresponding operation execution request (command) is transmitted to the corresponding MFP 10 (MFP 10 that transmitted the operation instruction) as a response (operation instruction response) to the received operation instruction (S417).

Upon receiving the operation instruction response (execution request) from the external application 231 by the communication processing unit 121, the application selection unit 122 of the MFP 10 sends the operation instruction response to the control unit 124 (S418, S419).
Upon receiving the operation instruction response from the application selection unit 122, the control unit 124 executes the operation (command processing) requested by the operation instruction response (execution request).

On the other hand, if the external application 231 fails in authentication, that is, if the authentication information added to the received operation instruction does not match the authentication information sent in advance to the MFP 10 that is the source of the operation instruction, The processing of the content of the operation instruction is rejected (S416 ′), and a response indicating that the operation is not possible (operation impossible response) is transmitted to the corresponding MFP 10 (the MFP 10 that has transmitted the operation instruction) (S417 ′).
When the communication processing unit 121 receives the operation disable response from the external application 231, the application selection unit 122 of the MFP 10 sends the operation disable response to the control unit 124 (S 418 ′, S 419 ′).

In the above-described processing, the MFP 10 transmits an MFP activation notification to each external application when the MFP 10 is turned on (powered on). However, the notification is sent at other timing (for example, by a key operation on the operation unit 107). Instructions). Alternatively, when an external application is activated while the power of the MFP 10 is turned on, the external application can specify the MFP 10 and transmit a notification of availability of its own application to the MFP 10.
Further, the above-described authentication process by the MFP 10 and the external application can of course be performed during communication other than the communication between the MFP 10 and the external applications 231 and 232 described with reference to FIGS.
In the third embodiment, the same effects as in the first embodiment can be obtained. In addition, since the authentication process is performed when the MFP 10 and the external application communicate with each other, security is improved.
