Description

The present invention relates to an image forming apparatus, an information processing method, and a program.

2. Description of the Related Art Conventionally, a method of setting an image forming apparatus such as a multifunction machine using an operation screen is known.

As for the system settings of the main body of the MFP, there is known a technique of storing setting values set on an operation screen in a storage device of the MFP (see, for example, Japanese Patent Application Laid-Open No. 2002-200013).

However, in the case of an image forming apparatus or the like in which the main unit and the operating unit have different configurations, the setting values may be stored separately for the main unit side and the operating unit side. Specifically, setting values such as various initial settings for copying, scanning, and the system are stored on the main body side. On the other hand, setting values specific to each operation unit such as the volume level on the operation unit, installation or uninstallation of application software on the operation unit, or setting values of applications installed on the operation unit, etc. stored in In such a case, setting values that are difficult to handle on the main unit side may be included. Therefore, setting values that are not inspected may occur.

An object of one aspect of the present invention is to inspect setting values of a main unit and an operation unit in an image forming apparatus.

An image forming apparatus having an operation device according to one embodiment of the present invention comprises:
a first setting unit that receives initial settings for the image forming apparatus and stores them in a first storage unit;
a second setting unit that receives settings made by the operating device and stores them in a second storage unit that the operating device has;
a determination unit that determines whether the setting value is the first setting value set by the first setting unit or the second setting value set by the second setting unit;
an inspection unit that causes the operating device to inspect the second set value among the set values including the first set value and the second set value based on the determination result of the determination unit. .

According to the embodiment of the present invention, it is possible to inspect the setting values of the main unit and the operation unit in the image forming apparatus.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode for carrying out the invention will be described with reference to the drawings.

<Example of image forming apparatus>
FIG. 1 is a schematic diagram showing an example of the overall configuration of an image forming apparatus. As illustrated, the image forming apparatus 100 is, for example, an MFP (Multifunction Peripheral). Therefore, for example, the image forming apparatus 100 has image processing functions such as a copy function, a scanner function, a facsimile function, and a printer function. Note that the image forming apparatus 100 may further have other functions (for example, an error display function, etc.).

In this example, the image forming apparatus 100 is configured to have an operation device 110 . On the other hand, the image forming apparatus 100 has a configuration other than the operation device 110 (hereinafter referred to as “main unit 120”).

A user inputs various operations to the image forming apparatus 100 through the operation device 110 . Then, the image forming apparatus 100 executes image processing based on the operation by the operation device 110 and the main unit 120 .

<Hardware configuration example>
FIG. 2 is a block diagram showing a hardware configuration example of the operating device and the main body. First, the operation device 110 includes, for example, a CPU (Central Processing Unit, hereinafter referred to as "CPU 211"), a ROM (Read-Only Memory, hereinafter referred to as "ROM 212"), and a RAM (Random Access Memory, hereinafter referred to as "RAM 213"). ), a flash memory 214, an operation panel 215, a connection interface (hereinafter referred to as “connection I/F 216”), and a communication interface (hereinafter referred to as “communication I/F 217”). Also shown, these hardware resources are interconnected by a bus 218 .

The CPU 211 is an example of an arithmetic device and a control device. The CPU 211 executes various programs stored in the ROM 212, the flash memory 214, etc., using the main storage device such as the RAM 213 as a work area. Through such control and calculation, the CPU 211 controls the operation device 110 and the like and implements various functions.

Flash memory 214 is an example of a non-volatile storage medium. For example, flash memory 214 stores programs, data, and the like.

Operation panel 215 is an example of an input device and an output device. That is, the operation panel 215 displays an operation screen, processing results, and the like. On the other hand, operation panel 215 accepts user operations.

The connection I/F 216 is an interface that communicates with the main unit 120 via the communication path 230 . For example, the connection I/F 216 is a connector, cable, and the like. Specifically, the connection I/F 216 performs communication by USB (Universal Serial Bus) or the like.

A communication I/F 217 is an interface for communicating with an external device via the network 260 . For example, the communication I/F 217 is an antenna or the like. In the illustrated example, the communication I/F 217 connects to a wireless LAN (Local Area Network) AP (access point) (hereinafter referred to as "wireless LAN AP 240") to perform communication.

On the other hand, the main unit 120 has a hardware configuration including, for example, a CPU 221, a ROM 222, a RAM 223, a HDD (Hard Disk Drive, hereinafter referred to as "HDD 224"), an engine unit 225, a connection I/F 226, and a communication I/F 227. is. Also shown, these hardware resources are interconnected by a bus 228 .

The CPU 221 is an example of an arithmetic device and a control device. That is, as shown in the figure, the arithmetic device and control device for the main unit 120 preferably have a hardware configuration different from that of the CPU 211 for the operation device 110 .

Like the CPU 221, the ROM 222 and the RAM 223 are examples of storage devices for the main unit 120. FIG. Therefore, the CPU 221 uses the main storage device such as the RAM 223 to execute processing based on programs and the like stored in auxiliary storage devices such as the ROM 222 and the HDD 224 .

The engine unit 225 is a processing device or the like for realizing image processing functions such as a copy function, a scanner function, a facsimile function, and a printer function. Specifically, the engine unit 225 is, for example, a processing IC (Integrated Circuit). Specifically, the engine unit 225 has a scanner that scans and reads an original, a plotter that prints on sheet materials such as paper, a communication unit that performs facsimile communication, or a combination thereof. The engine unit 225 may include a device for sorting printed sheet materials, a so-called finisher, an ADF (Auto Document Feeder) for automatically feeding documents, or the like.

The connection I/F 226 is an interface that communicates with the operating device 110 via the communication path 230 . For example, the connection I/F 216 is a connector, cable, and the like. Specifically, the connection I/F 226 performs communication by USB or the like.

A communication I/F 227 is an interface for communicating with an external device via the network 260 . For example, the communication I/F 227 is the cable 250 or the like.

<Example of operating device>
FIG. 3 is a schematic diagram showing an example of the appearance of the operating device. For example, the operating device 110 is a device having an appearance as illustrated. Specifically, the operation device 110 displays operation screens for various functions provided by the image forming apparatus using the operation panel 215 or the like, for example. In this example, the operation screen accepts operations for functions of "copy", "scanner", "fax" and "printer". The illustrated example is a so-called top screen. For example, when the "copy" button is pressed, the operation screen displays an operation screen for making detailed settings for the "copy" function.

Also, when a button is pressed on the operation screen, the next screen to be displayed or the set values to be set are set according to the menu configuration or the like.

Note that the operation device 110 is not limited to being realized by the operation panel 215 as shown. For example, the operation panel 215 may have hard keys and the like in addition to the touch panel. That is, the configuration that serves as an interface for operating the operation screen may be a configuration other than that illustrated.

Furthermore, as illustrated, the operation screen has a help button 300 . An example in which preset help contents are displayed on the screen when the help button is pressed will be described below. In this manner, by pressing the help button 300, the user can refer to so-called help, manuals, and the like. It should be noted that a method other than pressing the help button 300 may be used to refer to the help content. Also, the file providing the referenced help content may be stored in the operation device 110 or the main unit 120, or may be referenced online via the network.

<Software configuration example of operating device and main unit>
FIG. 4 is a block diagram showing a software configuration example of the operating device and the main unit. The illustrated example shows a hierarchical structure of software configured by programs installed in the operation device 110 and the main unit 120 .

First, the body portion 120 will be described. In this example, a program for constructing an application layer 421, a service layer 422 and an OS layer (operating system layer, hereinafter referred to as "OS layer 423") is installed in an auxiliary storage device or the like in the main unit 120. .

Programs classified in the application layer 421 operate hardware resources of the image forming apparatus 100 to realize various functions. Specifically, programs classified into the application layer 411 are, for example, a copy application, a facsimile application, a scan application, a printer application, and the like.

Programs classified into the service layer 422 are programs interposed between the application layer 421 and the OS layer 423 . For example, the programs classified into the service layer 422 use the hardware resources of the main unit 120 by the programs of the application layer 421, or notify the application layer 421 of the state of the hardware resources of the main unit 120. Realize an interface etc.

Also, the programs classified into the service layer 422 receive operation requests for hardware resources, or arbitrate the received operation requests. In addition, the programs partitioned in the service layer 422 send errors detected in hardware resources to the application layer 421 as error notifications. The operation request received by the service layer 422 includes, for example, an operation request such as reading by a scanner or printing by a plotter.

It should be noted that the role of the interface realized by the programs classified into the service layer 422 is the same for the application layer 411 of the operation device 110 . That is, a program classified into the application layer 411 of the operation device 110 can access the service layer 422 to operate the hardware resources of the main unit 120 to realize image processing functions and the like.

Programs classified into the OS layer 423 are programs called so-called basic software. Programs classified into the OS layer 423 provide basic functions for controlling hardware resources of the main unit 120 . First, a program classified into the service layer 422 converts an operation request for hardware resources issued by a program classified into the application layer 421 into a command that can be interpreted by the OS layer 423 and passes the command to the OS layer 423 . Then, the program classified in the OS layer 423 executes the command, thereby realizing the image processing function based on the operation request to the hardware resource. Also, when a program partitioned in OS layer 423 is executed, hardware resources receive detected errors. The hardware resource then passes the received error notification to service layer 422 which forwards it to application layer 421 .

Next, the operating device 110 will be described. In this example, the operating device 110 is installed with a program for constructing an application layer 411, a service layer 412, and an OS layer 413, for example, in an auxiliary storage device or the like.

However, the functions realized by the programs classified into the application layer 411 and the types of operation requests that the service layer 412 can accept are different from those of the main unit 120 . Specifically, in the operation device 110 , programs classified into the application layer 411 mainly provide user interface functions for performing operations and displays related to image processing functions realized by the main unit 120 .

In this example, the OSs of the operation device 110 and the main unit 120 operate independently. Also, as long as the operation device 110 and the main unit 120 can communicate with each other, the respective OSs do not have to be of the same type. For example, the operation device 110 may use Android (registered trademark), and the main unit 120 may use Linux (registered trademark).

As described above, in the image forming apparatus 100, for example, the operation device 110 and the main unit 120 are controlled by different OSs. Therefore, communication between the operation device 110 and the main unit 120 is not communication between processes within one device, but communication between different devices. For example, the communication may be command communication in which the operation device 110 receives a user operation and transmits it to the main unit 120, or event communication in which the main unit 120 instructs the operation device 110 to display a display screen (for example, an error notification or an error message). cancellation notice, etc.).

<System configuration example>
FIG. 5 is a block diagram showing a system configuration example of an image forming apparatus. For example, as illustrated, the image forming apparatus 100 has a system configuration having an operation device control unit 501 on the operation device side and a main body control unit 502 on the main body side. The body control unit 502 can be accessed from an external device. In the illustrated example, a PC (Personal Computer, hereinafter referred to as "PC 500") is an example of the external device.

The operating device control unit 501 is configured to control the operating device. For example, the operation device control unit 501 is configured to have a client application 503 as illustrated. Furthermore, the operating device is equipped with an application function corresponding to the installed application software. In the illustrated example, there are applications such as a copy application 506, a facsimile application 507, and a scan application 508 on the operation device. Note that the configuration of the application is determined by the installed program. Therefore, the application may have a help service and the like.

The client application 503 is an example of an application that displays an operation screen for receiving operations on the image forming apparatus 100 . For example, the client application 503 has a configuration including a browser (hereinafter referred to as a “browser 504”) and an operation unit database 505, as illustrated.

The browser 504 displays, for example, an operation screen or the like. Note that the operation screen may be displayed by software other than the browser 504 . Therefore, the browser 504 may be software such as a native application pre-installed in the operation device as long as it can display the operation screen.

The operation unit database 505 is an example of a configuration for managing application setting values in the operation device control unit 501 . Therefore, in this example, the operation unit database 505 collectively manages the setting values used by each application. Specifically, the operation unit database 505 transmits and receives setting values to and from each application. Items managed by the operation unit database 505 may be added by installed programs. Note that the operation unit database 505 may be configured not to be included in the client application 503 but to be included in other software or the like.

A copy application 506 is an application for copying by the image forming apparatus 100 .

A facsimile application 507 is an application for performing facsimile communication by the image forming apparatus 100 .

A scan application 508 is an application for scanning an image written on a sheet or the like by the image forming apparatus 100 .

For example, applications such as the copy application 506, the facsimile application 507, and the scan application 508 manage unique setting values within each application. Note that the application does not have to have the means for setting the setting values.

A body control unit 502 is configured to control the body of the image forming apparatus 100 . For example, the body control unit 502 is configured to have a web server module 509 as shown. Also, in this example, the web server module 509 is configured to have a menu configuration file 510, a main body database 511, and the like.

The web server module 509 collectively manages setting values on the main unit side, for example. Also, as shown, the web server module 509 communicates with the client application 503 and the like. The web server module 509 then merges menus and the like that can be acquired through communication to generate a menu structure. In this example, the menu configuration file 510 is data representing the menu configuration.

The menu configuration file 510 is data that stores a menu configuration of setting values in the image forming apparatus 100 . Specifically, the menu configuration file 510 indicates which category each setting value belongs to in the menu configuration, and what kind of hierarchical structure the category has in the menu configuration. Details of the menu configuration file 510 will be described later.

The main unit database 511 is an example of a configuration for managing setting values in the main unit control unit 502 . Therefore, in this example, the main body database 511 collectively manages the setting values used by each module. Specifically, the main body database 511 transmits and receives setting values to and from each module. Items managed by the main body database 511 may be added by installed programs. Note that the main unit database 511 may be configured not to be included in the web server module 509 but to be included in another module or the like.

Furthermore, the main unit is equipped with a module corresponding to the installed software. In the illustrated example, modules such as a network module 512, a scan module 513, and a print module 514 are provided in the main body. Note that the module configuration is determined by the installed programs and the like. Note that the module may be, for example, a fax or the like.

Network module 512 communicates using a network.

A scan module 513 scans an image using a scanner or the like.

The print module 514 forms an image on paper or the like using a printing device or the like.

A GUI (Graphical User Interface, hereinafter simply referred to as "GUI 515") makes an HTTP request to the web server module 509 or the like. A GUI 515 displays a UI (User Interface) and posts setting values.

The first setting module 516 and the second setting module 517 use a database or the like to set setting values and check setting values.

The PC 500 is an information processing device. Then, the PC 500 is connected to the same network as the image forming apparatus 100 as illustrated. Also, in this example, the PC 500 has a browser. Therefore, when the web server module 509 permits access from the PC 500 , the PC 500 can remotely configure the image forming apparatus 100 . Note that the PC 500 may be omitted. Also, the PC 500 may be of another type as long as it is an information processing device.

<Operation screen example>
The system configuration described above enables, for example, the following operation screen display and screen transition.

FIG. 6 is a diagram showing an example of an operation screen for category selection. An example in which the illustrated first screen 600 is displayed by the operating device, that is, the client application will be described below.

The first screen 600 displays settings separately for each category. In the illustrated example, "texture and print settings", "data management", "document management", "security", "function restrictions", "authentication/accounting settings", and "user authentication management" on the first screen 600 are categories. This is an example of a GUI that shows names and serves as buttons for making selections. By pressing one of these GUIs, the user can make detailed settings for each category and confirm the details of the settings.

In the following, for example, an operation of pressing the "user authentication management" button 601 will be described as an example. When such an operation is performed, the first screen 600 transitions to, for example, the following screen.

FIG. 7 is a diagram showing an example of an operation screen for detailed settings. For example, when the button 601 is pressed on the first screen 600, the operation screen transitions so that the illustrated second screen 700 is displayed.

The second screen 700 is an operation screen for confirming and setting setting values in "user authentication management". Specifically, on the second screen 700, the user can set the setting value by selecting "scanner" or the like or by selecting an option from a pull-down menu. Also, in this example, when the "OK" button is pressed, the set values are confirmed and updated.

As described above, the operation screen transitions from the first screen 600 to the second screen 700, for example. In this way, how the operation screens are transitioned, that is, the relationship between a plurality of operation screens is determined by the menu configuration file or the like. Furthermore, in the example described below, it is assumed that the setting values to be set on the operation screen are also determined by the menu configuration file.

<Example of menu configuration and menu configuration file>
FIG. 8 is a diagram showing a menu configuration example. A menu configuration 800 as shown will be described below as an example. Specifically, in this example, "TOP" is the highest hierarchical level of the so-called tree-structured menu structure. Therefore, in the menu configuration 800, menus such as "system", "facsimile", "scanner" and "printer" can be selected on the "TOP" operation screen. Next, for example, on the operation screen for "system", menus such as "basic", "network" and "administrator" can be selected. In this manner, a lower hierarchy to which a transition is to be made can be selected on the operation screen that is a higher hierarchy. Then, when the selection is made, the operation screen transitions to a lower hierarchy. Hereinafter, the layer that becomes "TOP" is referred to as "first layer". A layer below "TOP" is called a "second layer". Similarly, this example assumes a hierarchical structure with further "third hierarchy", "fourth hierarchy" and "fifth hierarchy".

Thus, the menu configuration file is data that defines the menu configuration 800. FIG. Therefore, if there is a menu configuration file, it is possible to specify what kind of structure is from the "TOP" to the operation screen for setting the setting values.

For example, in the illustrated menu structure 800, the transition is as follows.

FIG. 9 is a diagram showing a transition example of operation screens. An operation screen as shown in the figure that is displayed when operating the "system" in the menu configuration 800 will be described below as an example.

In this example, first, when an operation is performed to switch from "TOP" to "SYSTEM", the screen shown in FIG. 9A (hereinafter referred to as "second hierarchy screen 901") is displayed. As shown, the second layer screen 901 is an example of an operation screen that allows the user to select from three menus of "basic", "network" and "administrator" based on the menu configuration file or the like.

That is, when a selection is made on the second layer screen 901, the operation screen transitions from the display as shown in FIG. 9A to the display as shown in FIG. 9B. An example in which the operation screen transitions from the second hierarchical screen 901 to the screen shown in FIG. 9B (hereinafter referred to as the "third hierarchical screen 902") will be described below.

Further, in this example, when a selection is made on the third hierarchy screen 902, the display as shown in FIG. 9B is changed to the display as shown in FIG. 9C. An example in which the operation screen transitions from the third hierarchical screen 902 to the screen shown in FIG. 9C (hereinafter referred to as the "fourth hierarchical screen 903") will be described below.

In this example, the second hierarchy screen 901 and the third hierarchy screen 902 are examples of operation screens for changing the hierarchy. In other words, in this example, the second layer screen 901 and the third layer screen 902 are screens composed of so-called link options.

On the other hand, the fourth layer screen 903 is an operation screen for setting setting values for "item A", "item B", and "item C".

These operation screens are generated, for example, based on definitions defined by the following codes.

FIG. 10 is a diagram showing a code example for generating the third layer screen. For example, the third layer screen 902 is generated based on the code as shown.

FIG. 11 is a diagram showing a code example for generating the fourth hierarchy screen. For example, the fourth layer screen 903 is generated based on the code as shown.

Specifically, "id" is a number or the like for identifying each operation screen. That is, if the "id" can be specified, it is possible to specify which operation screen is indicated in the data such as the code.

"title" is data indicating the name of the category. In this example, the "title" and the block in the menu configuration 800 match. Also, in this example, the characters input to "title" are displayed on the upper left of the operation screen.

“category” or “window” is set in “type”. “Category” defines an operation screen for changing the hierarchy, such as the second hierarchical screen 901 and the third hierarchical screen 902 . On the other hand, “window” is defined as an operation screen for operating setting values such as the fourth layer screen 903 .

"children" defines an operation screen as a lower layer. For example, in the menu structure 800, the operation screens of "item A", "item B", and "item C" are defined in the fifth layer, which is the lower layer of the "setting screen" of the fourth layer. Therefore, on the fourth layer screen 903, "id" of each of "item A", "item B" and "item C" is defined as "children". In this way, a tree structure like the menu structure 800 is constructed.

<Setting value example>
For example, setting values such as "item A", "item B", and "item C" can be set using a setting screen such as the fourth hierarchy screen 903 or the like. The setting values and setting screens are stored in the form of a table, database, or the like, for example. Specifically, in the example of the menu configuration 800, it is assumed that "item A" is stored in a table (hereinafter referred to as "first table 801"). Similarly, in the example of the menu configuration 800, it is assumed that "item B" is stored in a table (hereinafter referred to as "second table 802").

Specifically, for example, “item B” is defined by the second table 802 as shown below (Table 1).

上記（表１）において、「ｉｄ」は、設定値に割り当てられる識別番号等である。

In the above (Table 1), "id" is an identification number or the like assigned to the setting value.

"title" is the name of each setting value and setting screen.

"type" indicates the type of format for inputting the setting value. For example, “type” is set to “numerical input”, “alternative selection”, “character input”, or the like. Then, when "type" is set to "numerical input", the setting value is set by a numerical value. Also, when "type" is set to "alternative selection", the set value is set to select from options prepared in advance. Furthermore, when "type" is set to "character input", the set value is set in characters or the like.

"min" is the setting of the minimum value. Therefore, if a value smaller than "min" is set as the set value, an error or the like will occur.

"max" is the setting of the maximum value. Therefore, if a value larger than "max" is set as the set value, an error or the like will occur.

"step" is the setting of the number of steps.

"access roll" is an access right. Specifically, "administrator", "guest", or the like is set. For example, if "administrator" is set, the setting value can only be set by a user with administrator authority.

"value" is the acquisition destination of the setting value.

Also, the set value may include "peripheral device" or the like. In this example, "item B" indicates a setting value used when a "finisher" is connected as a peripheral device to the image forming apparatus. Thus, "peripheral device" indicates the type of peripheral device to which the setting value relates. When setting values and peripheral devices are associated with each other in this manner, the type of peripheral device corresponding to each setting value can be identified.

A table such as the above (Table 1) is stored separately in the main unit and the operating device.

For example, the image forming apparatus can display an operation screen when there is a menu configuration file and table as described above.

<Overall processing example>
FIG. 12 is a sequence diagram illustrating an example of overall processing. A case where the user 1201 sets a setting value using the operation device 110 will be described below as an example.

In step S101, the browser 504 accepts settings. For example, the user 1201 performs an operation of inputting a character string or the like in settings on the browser 504 . A case where a character string is input will be described below as an example.

In step S102, the browser 504 notifies a character string or the like.

In step S103, the GUI 515 inspects the character string and the like. Specifically, in step S103, the character string is inspected within a range that can be inspected according to a rule that can be used in common by the operation device 110 and the main unit 120 (hereinafter referred to as "common rule"). Details of the inspection will be described later.

Next, as a result of the inspection, if there is an error ([if there is an error]), the GUI 515 proceeds to step S104. On the other hand, if the result of the inspection is that there is no error ([no error]), the GUI 515 proceeds to step S107.

In steps S104, S105 and S106, browser 504 and GUI 515 display an error. In this way, the user 1201 can see that there is an error in the input setting value.

In step S107, the GUI 515 requests determination as to whether the set value is the set value of the main unit or the set value of the operating device.

In step S108, the web server module 509 determines whether the setting value is the setting value of the main unit or the setting value of the operating device. For example, determination is made based on "id" or the like. Specifically, it is assumed that data used for determination is set in advance as a part of "id". In this way, the web server module 509 uses part of the “id” to determine whether it is the setting value of the main unit or the setting value of the operating device.

Next, if the determination result indicates that it is the setting value of the operation device ([in the case of the operation device]), the web server module 509 proceeds to step S109. On the other hand, if the result of determination is that it is the set value of the main unit ([in the case of the main unit]), the web server module 509 proceeds to step S117.

In step S109, the web server module 509 requests the client application 503 to inspect. For example, when the inspection is performed using the operation device, the inspection is realized by the processes such as steps S110 and S111 described below. Note that the inspection method is not limited to the method described below.

In step S110, the client application 503 performs inspection based on rules set in advance in the operation device (hereinafter referred to as "operation unit rules"). Operation unit rules and inspection will be described later.

In step S111, the client application 503 inquires of the second setting module 517 whether or not the setting value to be inspected can be set.

In step S112, the client application 503 returns the result of the inspection in steps S110 and S111.

Specifically, for example, the following source code is used. The source code is an example of JSON (Javascript (registered trademark) Object Notation) format. However, the source code may be written in other formats.

FIG. 13 is an example of source code requesting inspection. For step S109, for example, a source code as illustrated is used.

“requestId” is a so-called identification number of a request requesting inspection. Therefore, the "requestId" of the inspection request (step S109) and the corresponding response (step S112) match.

"check" indicates an object to be checked.

"lang" specifies the language. As shown in the figure, "ja" is Japanese.

"items" is data used for inspection. Specifically, "id" in "items" is data for identifying a setting value. Also, "value" in "items" is the input setting value, that is, the setting value or the like input in step S101.

Then, for example, the client application 503 executes a check function or the like to inspect the request as shown. The client application 503 responds with the result of such inspection, for example, as the following source code.

FIG. 14 is an example of a source code that returns inspection results. For example, the following responses are made to the requests shown in FIG.

As shown, a code indicating the inspection result (hereinafter referred to as "inspection result code 1401") is returned.

"length" in the inspection result code 1401 indicates the result of inspecting the length of the character string that is the set value. In other words, when the check function is executed, the number of characters in the character string used as the set value is counted. Then, the inspection result code 1401 returns the count number and the like.

"error" in the inspection result code 1401 indicates the result of inspecting whether there is an error in the character string used as the setting value. In other words, by executing the check function, it is possible to check whether or not the character string that is the setting value contains characters that are prohibited from being used in advance. If the set value causes an error, for example, as shown in the figure, the inspection result code 1401 returns the details of the error.

In step S113, the web server module 509 notifies the operation device of the inspection result.

In steps S114, S115 and S116, browser 504 and GUI 515 display an error, if any. In this way, the user 1201 can see that there is an error in the input setting value.

On the other hand, when the inspection is performed by the main unit, the inspection is realized by the following processes such as steps S117 and S118. Note that the inspection method is not limited to the method described below.

In step S117, the web server module 509 performs inspection based on a rule preset in the main body (hereinafter referred to as "main body rule"). Body rules and inspections will be described later.

In step S118, the web server module 509 inquires of the first setting module 516 whether or not the setting value to be checked can be set.

In step S119, the web server module 509 replies with the results of the checks in steps S117 and S118.

In steps S120, S121 and S122, browser 504 and GUI 515 display an error, if any. In this way, the user 1201 can see that there is an error in the input setting value.

For example, an operation screen or the like for setting setting values is generated and displayed as follows.

<Display example of the operation screen for setting the setting value>
FIG. 15 is a sequence diagram illustrating an example of processing for generating and displaying an operation screen for setting setting values. For example, a case where an operation to select a “setting screen” is performed on the third layer screen 902 will be described as an example. That is, the illustrated process is a process of displaying the setting screen according to the user's instruction (for example, in FIG. 9B, according to the user's operation to select the item of the "setting screen"). is.

In step S201, the client application 503 accepts an operation to select "setting screen".

In step S202, the client application 503 inquires about setting values. Specifically, the client application 503 stores "item A", "item A", It can be seen that the menu configuration has setting values for "item B" and "item C". Furthermore, if there is a menu configuration file or the like, "id" or the like that can specify "item A", "item B" and "item C" can be found. Therefore, the client application 503 uses, for example, the “id” of “item A”, the “id” of “item B”, and the “id” of “item C” to query the web server module 509 . In this way, the client application 503 requests the setting values of “item A”, “item B”, and “item C” from the web server module 509 .

In step S203, the web server module 509 determines whether the setting value to be queried is the setting value of the main unit or the setting value of the operating device.

In this example, when the "id" is known, the web server module 509 determines whether the target setting value is the setting value of the main unit or whether the target setting value is the setting value of the operation device. Suppose you can. Specifically, it is assumed that "id" has the following configuration and settings.

問い合わせには、例えば、上記（表２）における「ｉｄ」のようなデータが用いられる。この例では、「ｉｄ」のデータ（１６桁であるとする。）のうち、上位ビットの８桁と、下位ビットの８桁とに分けて、「ｉｄ」は、管理されるとする。

Data such as "id" in the above (Table 2), for example, is used for the inquiry. In this example, the "id" is managed by dividing the "id" data (assumed to be 16 digits) into 8 high-order bits and 8 low-order bits.

As described above, if the high-order bit is "3", it is determined that the setting value to be inquired is the setting value of the main unit. On the other hand, if the upper bit is "11", it is determined that the setting value to be inquired is the setting value of the operating device. In addition, if the upper bit is "1677787392", it is determined that the setting value to be inquired is the setting value of the third vendor application. Then, when it is determined to be the setting value of the third vendor application, it is further determined whether it is the setting value of the main unit or the setting value of the operation device.

Next, it is assumed that the web server module 509 or the like can specify the setting value by using the lower bits. That is, the lower bit value is a number that can identify the set value.

Subsequently, when it is determined that the setting value to be queried is the setting value of the main unit ([if the target setting value is the main unit]), the web server module 509 proceeds to step S204. On the other hand, if it is determined that the setting value to be queried is the setting value of the operating device ([if the target setting value is the operating device]), the web server module 509 proceeds to step S206.

In step S204, the web server module 509 inquires of modules such as the network module 512 about setting values. Whether or not the destination of the inquiry is the network module 512 depends on the setting value.

In step S<b>205 , the network module 512 and the like return the setting values to the web server module 509 .

Steps S204 and S205 are so-called inter-process communications because they are communications within the main unit. In this way, the web server module 509 inquires of each module about the setting value that is the object of the inquiry. By doing so, the web server module 509 acquires the latest set values.

In step S206, the web server module 509 inquires of the operation unit database 505 about setting values. For example, the query is based on the following source code.

FIG. 16 is an example of source code for inquiring about setting values. For example, when an inquiry is made with a code for specifying "id" (hereinafter referred to as "specified code 1601") as shown in the figure, an inquiry is made for a setting value with "id" of "0000000300000065". The inquiry may include settings such as setting the language to Japanese, such as "ja" for "lang", as shown in the figure.

In step S207, the operation unit database 505 reads the database in response to the inquiry.

In step S208, the operation unit database 505 responds with setting values in response to the inquiry. For example, the following reply is made.

FIG. 17 is an example of source code for replying to an inquiry about setting values. Specifically, in the illustrated source code, a code for replying a setting value such as "title" (hereinafter referred to as "setting value code 1701") is the reply to the inquiry in step S206.

Specifically, the setting value code 1701 returns the latest setting value set in the application, module, or the like for the item specified by “id” in the specification code 1601 .

In step S209, the web server module 509 notifies setting values and the like. That is, the web server module 509 acquires the setting value in step S205, step S208, or the like according to the inquiry. Then, in step S209, the web server module 509 notifies the client application 503 of the acquired setting values and the like.

In step S210, the client application 503 draws the screen.

In step S211, the client application 503 displays the drawn screen.

For example, a screen such as an operation screen is drawn and displayed as follows.

FIG. 18 is an image diagram of an example of screen drawing processing. The illustrated image diagram shows an example of processing for drawing the setting screen 1804 based on the object.

First, the system program or the like draws the setting value “application E setting” set in the “title” of the “parent” (upper hierarchy) in the setting structure 1801 at the “screen title display position” in the screen template 1803 . Also, the system program sequentially reads elements of the hierarchy that are “children” of the setting structure 1801 . Next, the system program draws the drawing template 1802 corresponding to the setting type of the read "child" element on the screen template.

For example, the system program first reads the drawing template of the setting type "numerical type" corresponding to the setting type of the element with the ID "E001" which is the "child" in the illustrated example. Next, the system program draws on the screen template 1803 , that is, draws the “reset timer” setting item on the setting screen 1804 .

As with the ID "E001", the system program reads the drawing template of the setting type "alternative selection type" corresponding to the setting type of the element with the ID "E002" which is the "child" in the illustrated example. Next, the system program draws on the screen template 1803 , that is, draws the “default color mode” setting item on the setting screen 1804 .

Furthermore, similarly to the ID "E001", the system program reads out the drawing template of the setting type "alternative selection type" corresponding to the setting type of the element of ID "E003" which is the "child" in the illustrated example. Next, the system program draws on the screen template 1803 , that is, draws the “application E energy saving priority setting” setting item on the setting screen 1804 .

As a result of such drawing, the system program can generate a setting screen 1804 such as the added "application E" and display it on a browser or the like used by the image forming apparatus.

By performing the above processing, it is possible to display an operation screen and setting values as shown in FIG. 9C, for example.

<Example of setting value update processing>
For example, when updating the setting value, the following processing may be performed.

FIG. 19 is a sequence diagram illustrating an example of processing for updating and displaying setting values. That is, the illustrated processing is such that the user changes the setting value on the displayed setting screen (for example, in FIG. 9C, the user sets "item A", "item B" or "item C" The value is set (changed) and an "OK" button is pressed.). An example based on the processing shown in FIG. 15 will be described below. Therefore, the same reference numerals are assigned to the same processes as those shown in FIG. 15, and overlapping descriptions are omitted.

The processing shown in this example differs in that step S301 is added.

Also, in step S201, the user 1201 further performs an operation to change the setting value.

In step S202, the client application 503 requests writing of the determined setting values.

In steps S204 and S206, the determined set values are written.

In steps S205 and S208, the write result is notified.

In step S209, the screen one level higher is drawn.

In step S301, the operation unit database 505 notifies the updated setting values.

Also, the image forming apparatus repeats, for example, the entire process until there is no error in the set values. Furthermore, the image forming apparatus may perform the following setting processing, for example.

FIG. 20 is a sequence diagram illustrating an example of processing for setting.

In step S401, the user 1201 presses a button to start setting.

In step S402, the browser 504 notifies that the button for starting setting has been pressed.

In step S403, the GUI 515 checks whether or not essential items have been entered in the setting values.

Next, if there is insufficient input for an essential item ([Insufficient input]), the GUI 515 proceeds to step S404. On the other hand, if the required items are not insufficiently entered ([not insufficiently entered]), the GUI 515 proceeds to step S406.

In steps S404 and S405, the browser 504 and GUI 515 display that the required items are insufficiently entered.

In step S406, the GUI 515 makes a request to set the setting value.

In step S407, the web server module 509 determines whether the setting value to be set is the setting value of the operating device or the setting value of the main unit.

Next, when it is determined that the setting value is the setting value of the operating device ([in the case of the operating device]), the web server module 509 proceeds to step S408. On the other hand, if it is determined that the setting value is the setting value of the main unit ([in the case of the main unit]), the web server module 509 proceeds to step S415.

In step S408, the web server module 509 requests the operating device to set the setting values.

In step S409, the client application 503 checks whether setting values can be set. Then, if the setting value can be set, the client application 503 performs step S410.

In step S410, the client application 503 sets setting values.

In step S411, the client application 503 notifies the result of setting.

In steps S412, S413 and S414, the web server module 509, browser 504 and GUI 515 display the results of the settings.

In step S415, the web server module 509 checks whether the setting value can be set. Then, if the setting value can be set, the web server module 509 performs step S416.

In step S416, the web server module 509 sets the setting values.

In steps S417, S418 and S419, the web server module 509, browser 504 and GUI 515 display the results of the settings.

For example, setting values are set as described above.

<Processing result example>
FIG. 21 is a diagram illustrating an example of a processing result; When the overall processing is performed, for example, the processing result shown in the figure is obtained.

First, in this example, it is assumed that the set value is set to a character "new password". Hereinafter, the characters indicating the "new password" input by operation on the operation screen as shown are referred to as "password 2101".

In this example, it is assumed that the maximum number of characters that can be set for the password 2101 is set to "128" by the rule. In other words, if the password 2101 is a set value for the main body, it is checked by the main body rule or the like. On the other hand, if the password 2101 is a setting value for the operation device, it is checked by the operation unit rule or the like.

In this example, the character count display 2102 displays the inspection result. The number-of-characters display 2102 indicates, for example, the value obtained by counting the number of characters of the password 2101 and the maximum value that can be set. Specifically, in the number-of-characters display 2102, “129” (value on the left side) indicates the number of characters of the password 2101 counted. On the other hand, in the number-of-characters display 2102, "128" (value on the right) indicates the maximum number of characters that can be set.

For example, the number-of-characters display 2102 indicates an error by displaying characters in red. Note that the error display method is not limited to the method of notifying in color, such as in red. For example, the error display method may be flashing of characters, highlighting of characters, display of an error message, warning sound, or a combination thereof.

In this example, an error occurs because the number of characters in the password 2101 is greater than the maximum value. In this way, it is possible to check whether there is an error in the set values.

<Regarding inspection, main unit rules, and operation unit rules>
What kind of inspection is to be performed, that is, common rules, main unit rules, and operation unit rules are set by, for example, the following management table or the like.

<Management table example>
For example, the main body rule is set by a management table or the like shown in Table 3 below.

すなわち、上記（表３）に示すような管理テーブルは、本体部に設定される。

That is, the management table as shown in the above (Table 3) is set in the main unit.

"Item name" indicates the name of the setting value.

"Item type" indicates the input format of the setting value. For example, if it is "STRING", the setting value is a character string input type. Also, if it is "NUMBER", the set value is a numerical input type. Note that the input format may have other formats.

"ID" is an identification number or the like for identifying a setting value. In this example, the upper four digits of "ID" indicate the module or the like that uses the set value. Specifically, the upper four digits are set such that "0001" indicates a network module, and "0002" indicates a scan module or the like. Also, when the upper four digits are "1001", it indicates that the "ID" is the setting value of the operating device. On the other hand, the lower four digits indicate items in each module. That is, when a module or the like handles a plurality of setting values, the lower four digits specify the setting value.

"Character code" indicates the character code for handling the setting value. Therefore, if there is no character code to set, the setting value cannot be handled. That is, the types of character codes that can be handled differ depending on the operating environment and the like. Therefore, even if the character codes can be handled by the operating device, the main body may not be able to handle them.

"Minimum value" indicates the minimum length of the setting value that can be set.

"Maximum value" indicates the maximum length of the setting value that can be set.

"Regular expression" indicates a character string that can be input as a regular expression.

"Check function" indicates a check function that is executed to check the set value.

"Dependent setting value" indicates a setting value that depends on setting the setting value. Specifically, an ID or the like is set in the "dependent setting value". The "dependent setting value" indicates a setting value that affects the setting range of the setting value. Specifically, when the password is a setting value, the "depending setting value" corresponds to, for example, a setting value for setting a security policy. Depending on the security policy, for example, the maximum or minimum number of characters constituting a password may be determined. In other words, a security policy may be set that requires a password with a number of characters that satisfies the security level. If setting values having a dependent relationship can be grasped in this way, inspection can be performed based on the dependent setting values.

In the following (Table 4) and the following (Table 5), items constituting the management table are the same.

例えば、上記（表４）のように、本体部と同様の形式となる管理テーブルが操作装置の方にも別個に設定される。このように、本体部と、操作装置とに別個に管理テーブルがあると、本体部ルールと、操作部ルールとが別個に設定できる。

For example, as shown in Table 4 above, a management table having the same format as that of the main unit is separately set for the operation device. In this way, if the main unit and the operating device have separate management tables, the main unit rule and the operating unit rule can be set separately.

For example, the main unit acquires the management table shown in (Table 4) above from the operation device when the application is started. Then, the management table shown in (Table 3) above and the management table shown in (Table 4) above are merged to generate, for example, a management table as shown in (Table 5) below.

上記（表５）と、上記（表３）とを比較すると、上記（表５）は、上記（表４）に示す「プロキシ設定－ユーザ名」の行が加わる点が異なる。つまり、上記（表５）は、上記（表４）の内容を取り込んでいるため、上記（表３）にないデータが加わる。

Comparing the above (Table 5) with the above (Table 3), the above (Table 5) differs in that the row of "proxy setting-user name" shown in the above (Table 4) is added. That is, since the above (Table 5) incorporates the contents of the above (Table 4), data not included in the above (Table 3) are added.

On the other hand, when comparing the above (Table 5) with the above (Table 4), in the above (Table 5), in the row of "proxy setting - user name", the "character code" and "check function" parts are The difference is that it is blank.

The reason why the column is blank in this way is that the character code set in the "character code" can be handled by the operating device but not by the main unit. Therefore, in the above (Table 5), the "character code" is blank.

Similarly, there are cases where the function set in the "check function" can be executed by the operating device but not by the main unit. Therefore, in the above (Table 5), the "check function" is blank.

As in the example shown in Table 5 above, there are setting values that can be inspected in the main unit and setting values that cannot be inspected. In such a case, it is determined whether the setting value is the setting value of the operation device or the setting value of the main unit, and the setting value of the operation device is checked by the operation device. It is possible to eliminate setting values that are not used.

In addition, it is often difficult to count the number of characters if the character code does not correspond. As a result, it may be difficult to check the maximum and minimum values. Therefore, it is desirable that the inspection be performed in an environment with the character code used to enter the setting value.

Similarly, check functions and the like are often difficult to execute if the function is not implemented. Therefore, it is desirable that the set value is inspected by executing the check function or the like in an environment where the check function can be executed.

In this example, "maximum value" and "minimum value" are examples of common rules. In other words, common rules may be set for inspections and the like that are performed in the same way for both the inspection of the operating device and the inspection of the main body. For example, common rules may be obtained as follows.

FIG. 22 is an example of source code showing acquisition of common rules and the like. For example, information about the common rule is acquired as a code as shown (hereinafter referred to as "common rule code 2201"). Common rule code 2201 includes, for example, the following information.

“id” is an identification number or the like for identifying a setting value. Similar to the above (Table 3), etc., in this example, the upper four digits indicate the module or the like that uses the set value.

"title" indicates the name of the setting value.

"type" indicates the input format of the setting value. "string" shown in the illustrated example is an example indicating that the input format is the character string input format.

"value" indicates the array key of the setting value. "UserA" shown in the illustrated example is an example indicating that characters "UserA" are set in the setting value.

"data" stores information for each set value. In this example, "data" stores "maxLength", "minLength" and "regExp". In this example, the items set to "data" are used in the common rule.

"maxLength" indicates the maximum length that can be set in the setting value. For example, "maxLength" is set by the number of bytes or the like. That is, in the illustrated example, the set value can be set as long as it is 100 bytes or less.

"minLength" indicates the minimum length that can be set for the setting value. For example, "minLength" is set by the number of bytes or the like. That is, in the illustrated example, the set value can be set as long as it is 0 bytes or more.

"regExp" indicates the type of characters that can be set in the setting value. For example, "regExp" is set by a regular expression or the like. That is, in the illustrated example, the set values can be set as long as they are Arabic numerals and alphanumeric characters (upper and lower case).

For example, there is a case where the setting value can be inspected regardless of the type of character code. Such set values may be checked, for example, by common rules or the like.

<Example of functional configuration>
FIG. 23 is a functional block diagram showing a functional configuration example of the image forming apparatus. For example, the image forming apparatus 100 has a functional configuration including a first storage unit 2309, a second storage unit 2310, a first setting unit 2301, a second setting unit 2302, a determination unit 2303, an inspection unit 2304, and the like. In addition, as illustrated, the image forming apparatus 100 preferably has a functional configuration further including a display unit 2305 and the like. The illustrated functional configuration will be described below as an example.

A first setting unit 2301 performs a first setting procedure for receiving initial settings for the image forming apparatus 100 . For example, the 1st setting part 2301 is implement|achieved by communication I/F227 grade|etc.,. Hereinafter, the setting value received by the first setting unit 2301 is referred to as "first setting value 2306".

A second setting unit 2302 performs a second setting procedure for receiving settings for the operating device. For example, the second setting unit 2302 is implemented by the operation panel 215 or the like. Hereinafter, the setting value received by the second setting unit 2302 will be referred to as a "second setting value 2307".

The determination unit 2303 performs a determination procedure for determining whether the setting value is the first setting value 2306 or the second setting value 2307 . For example, the determination unit 2303 is realized by the CPU 221 or the like.

Based on the determination result 2308 by the determination unit 2303 , the inspection unit 2304 performs an inspection procedure for causing the operating device 110 to inspect the second setting value 2307 among the setting values. For example, the inspection unit 2304 is implemented by the connection I/F 216 or the like.

A display unit 2305 performs a display procedure for displaying inspection results and the like. For example, the display unit 2305 is implemented by the operation panel 215 or the like.

The first storage unit 2309 stores initial settings. For example, the first storage unit 2309 is implemented by the main unit database 511 or the like.

A second storage unit 2310 is a storage unit included in the operation unit or the operation device. For example, the second storage unit 2310 is implemented by the operation unit database 505 or the like.

With the configuration as described above, the image forming apparatus 100 can set various setting values including the first setting value 2306 set by the initial setting or the like and the second setting value 2307 set by the operation device 110 or the like. can accept. Therefore, there are at least two types of setting values, a first setting value 2306 and a second setting value 2307 .

Therefore, the determination unit 2303 determines whether the setting value is the first setting value 2306 or the second setting value 2307 . Then, the inspection unit 2304 inspects the first set value 2306 and the like according to the common rule, the main unit rule, and the like. On the other hand, the second setpoint 2307 is checked on the operating device 110 . In this way, both the setting values of the main unit and the operating unit are inspected.

For example, the inspection unit 2304 inspects at least the length of the character string and whether there is an error in the setting value based on the input rule. In this way, it is possible to check whether there are too long character strings, too short character strings, and setting values that cause errors in the setting values. Therefore, the image forming apparatus 100 can have each setting value inspected by an appropriate apparatus based on the configuration of the associated apparatus. In this way, an inspection method suitable for each set value is applied. Therefore, the number of remaining characters that can be set and the presence or absence of errors can be displayed to the user. Then, the user can immediately check the inspection result even during input.

Also, it is desirable that the rules be set separately for the main unit and the operating device, such as the main unit rules and the operation unit rules. In this way, if rules are provided separately, inspection can be performed according to the character code of each device.

Furthermore, it is desirable that whether or not to allow the operation device 110 to perform inspection is determined based on the character code used to input the setting value. That is, the character code may be different between the main unit and the operating device. Therefore, there are some character codes that are handled only by operating devices. In such a case, it is desirable to check the setting value under the environment of the operating device that can handle character codes. In an environment that cannot handle character codes, for example, the number of characters cannot be counted. Therefore, if it is determined based on the character code whether or not the operating device is to be used as the environment for inspection, the number of characters of the setting value can be accurately inspected.

As described above, when there are a plurality of control units, the character code or input range may differ. Therefore, it may not be possible to accurately grasp the count, type, etc. of the set values. In such a case, it may not be possible to know whether there is an error or the like until the set values are actually set. Therefore, if it is determined in which environment the inspection should be performed, and the inspection is performed based on the determination result as in the present embodiment, errors in the set values can be detected even before setting.

Moreover, it is preferable that the operation for the set value is performed by the operation unit or the operation device, that is, the setting by the second setting unit is prioritized by exclusive lock or the like. Settings using an operation device or the like are often performed by approaching the image forming apparatus. Therefore, the person who performs the operation is less likely to use the network to perform unauthorized operations. Alternatively, there is a high possibility that the person who performs the operation will immediately use the image forming apparatus with the set values. Therefore, by prioritizing the operation using the operation device or the like over the operation using the browser or the like, user convenience can be improved.

Image forming apparatus 100 may be configured to include an operation unit. That is, the image forming apparatus 100 may be configured to include an operation unit implemented by an input device, an output device, or the like other than the operation device 110 . Then, the second set value may be accepted by the operation procedure of the operation unit.
