Description

Embedded system, image forming apparatus, and display method in embedded system

The present invention relates to an embedded system such as a machine or an apparatus and a display method in the embedded system. The present invention also relates to an image forming apparatus including an embedded system.

In an image forming apparatus such as a multifunction peripheral, a setting operation panel is provided. On the other hand, multi-functionality and advancement of image forming apparatuses are being promoted. For this reason, the setting operation on the operation panel tends to be complicated. As a result, the setting operation on the operation panel may be difficult to understand. An example of a technique for making settings on the operation panel easy to understand is described in Patent Document 1.

Specifically, in Patent Document 1, an operation panel having a setting operation instruction unit and a setting operation state display unit, a print output device, and manual information are held, and a user's setting operation sequence is extracted from an input setting operation. The extracted setting operation sequence is temporarily stored as user operation procedure information, manual information corresponding to the user's setting operation sequence is searched, and the user operation procedure is determined from the retrieved manual information and user operation procedure information. An electronic device with a setting operation manual creation device including a manual creation unit that creates and prints out a setting operation manual is described. With this configuration, a user-specific setting operation sequence is extracted so that the user himself can create a manual for daily work (see Patent Document 1: Claim 1, paragraph [0014]).

Japanese Patent Laid-Open No. 08-171589

In an embedded system such as an image forming apparatus, software (firmware, program) for causing a display operation on the display unit of the operation panel is also incorporated. In general, various types of firmware are incorporated in a form written in a ROM. The display content on the display unit in the embedded system, the display order of the setting screen (hierarchical structure), and the operation procedure are defined by the embedded firmware (firmware). The display contents, display order, and operation procedure are fixed and cannot be changed.

Since the user is not used to the newly introduced and installed image forming apparatus (embedded system), it may take time to set up the new image forming apparatus, or the operation procedure for obtaining a desired result may be difficult to understand. There is a problem. In particular, in an embedded system such as an image forming apparatus having a large number of setting screens and a large number of setting items and setting value candidates to be selected, it takes time to get used to the setting operation. In addition, the user can easily feel that the operation procedure is difficult to understand.

One of the causes is that the operation procedure between the image forming apparatus familiar with the setting operation and the new image forming apparatus is different. For example, an image forming apparatus accustomed to the setting operation and a new image forming apparatus have the same setting items and functions, but both image forming apparatuses have a hierarchical structure (display order) in display and setting items. There is a difference in classification. Therefore, it is confused with the previous operation of the image forming apparatus familiar with the operation. Also, in a new image forming apparatus, there may be no setting item or setting value key to be set in the hierarchy (position) expected by the user. As a result, the setting operation may be difficult to understand. This is particularly confusing when an image forming apparatus from a manufacturer different from the image forming apparatus that is used to the setting operation is introduced.

∙ Embedded system firmware is fixedly written in ROM and has a strong connection with hardware. For this reason, an embedded system such as an image forming apparatus cannot flexibly change the display flow and display contents such as a display hierarchical structure so as to be the same as a skilled image forming apparatus. In order to change the firmware, it is necessary to create and review new firmware source code, build the changed source code again, and update the firmware in the ROM to the one after the build. This is because it takes time and effort. When a ROM that cannot be rewritten is used, the ROM itself is replaced.

The technology described in Patent Document 1 allows individual users to create their own manuals. However, with the technology described in Patent Document 1, even in the case of a new image forming apparatus, although it is unfamiliar, it is necessary to create a manual by inputting on the operation panel. For this reason, the time required for creating the manual becomes longer. Moreover, there is a contradiction that in addition to the normal setting operation, it is necessary to become familiar with manual creation. Further, in order to enhance the contents of the printed manual, the number of printed sheets inevitably increases. There is no big difference from normal (prepared) paper manuals. Also, in order to ensure that the user's desired manual (highly satisfactory manual) is printed, it is necessary to understand the causal relationship between each of the many setting items and to respond to the extracted setting operation sequence. Therefore, it is necessary to search for relevant manual information without omission and perform processing. Therefore, it takes enormous time and labor for development. As described above, the technique described in Patent Document 1 has many disadvantages and cannot solve the problem that the operation procedure for obtaining a desired result with a new embedded system may be difficult to understand.

The present invention has been made in view of the above-described problems of the prior art. In an embedded system such as an image forming apparatus, the display unit is designed to be easily understood by a user without being updated by a firmware without a firmware update. It is an object to be able to change the display.

In order to solve the above problems, the embedded system according to the first aspect of the present invention relates to a display unit that displays a setting, an input unit that receives a setting input based on the display of the display unit, and a setting in the display unit An acquisition unit for acquiring a definition file for defining display contents, a display firmware for causing the display unit to display a setting, a storage unit for storing the acquired definition file, and the display firmware And a processing unit that causes the display unit to display the hierarchy defined in the definition file in accordance with the content of the setting operation performed on the input unit based on the acquired definition file.

According to the present invention, it is possible to change the display on the display unit in an embedded system such as an image forming apparatus without updating the firmware so that even a non-developer can easily understand the user. As a result, it is possible to provide an embedded system and an image forming apparatus that are easy to use for the user and provide high satisfaction.

Then, when switching the setting screen, the main control unit 10 reads out and reads out the data required for displaying the setting screen after switching from the display data D1 based on the function and command defined in the display firmware F14. The data is composed and a new setting screen is displayed on the display unit 1a.

(Printer storage unit 29)
Next, the printer storage unit 29 will be described with reference to FIG. FIG. 6 is a diagram for explaining the printer storage unit 29 according to the embodiment.

The printer storage unit 29 of the printer 2 of the present embodiment includes a ROM 29a, a RAM 29c, and an HDD 29b (see FIG. 6). The ROM 29a is mounted on the substrate of the printer control unit 20. As the ROM 29a, an EEPROM or a flash ROM can be used. The ROM 29a stores the firmware F2 of the printer 2 (stored in a nonvolatile manner).

Firmware F2 is software that is embedded to cause the embedded system 100 (printer 2) to perform a desired operation such as printing or display. The ROM 29a stores the firmware F2 that has been built by compiling and linking the source code (in an executable format).

The printer 2 of this embodiment has a printer function. As shown in FIG. 6, the printing firmware F21 is stored in the ROM 29a according to this function.

When printing data is input to the printer 2 via the communication unit 210, the printer control unit 20 executes the firmware F2 (printing firmware F21). The printer control unit 20 executes processing (commands, functions, routines) of the firmware F2 according to the setting operation performed on the operation panel 21 and the job execution instruction. As a result, the printer control unit 20 causes the printing unit 22 to perform printing.

The ROM 29a of the printer storage unit 29 stores display firmware F22 for causing the display unit 2a to display (switch the setting screen) in accordance with a setting operation on the operation panel 21 by the user. The display unit 2 a of the printer 2 is of a type that displays a character string, unlike that of the multifunction device 1. Therefore, the printer control unit 20 displays a character string (characters or symbols) on the display unit 2a based on the display firmware F22.

Further, in the display firmware F22, a character string (symbol, character) to be displayed next is determined in accordance with a setting operation on the hard key 2b provided on the operation panel 21 (details will be described later). ). When a setting operation is performed using the hard key 2b, the printer control unit 20 switches the character string to be displayed to the display unit 2a based on the display firmware F22.

When switching the display to the lower level setting screen (character string) in accordance with the setting operation (selected setting item) for the hard key 2b, the printer control unit 20 uses the display firmware F22 to display the lower level characters. The column is displayed on the display unit 2a. On the other hand, when a setting operation for returning to the upper layer is performed, the printer control unit 20 causes the display unit 2a to display a character string of the upper layer based on the display firmware F22.

Display data D2 for displaying the setting screen (data defining a character string to be displayed on the display unit 2a such as characters and symbols) may be stored in the ROM 29a or stored in the HDD 29b. May be. When the printer control unit 20 switches the character string (hierarchy) to be displayed, the printer control unit 20 needs the necessary data from the display data D2 stored in the ROM 29a or the HDD 29b based on the function or command defined in the display firmware F22. Data (character string) is read out, the read data is composed, and a new screen (character string) is displayed on the display unit 2a.

(Hierarchical structure of MFP 1 in the initial state)
Next, the hierarchical structure in the display of the MFP 1 in the initial state will be described with reference to FIGS. FIG. 7 is a diagram illustrating an example of the printing procedure of the network status report. FIG. 8 is a view for explaining a display hierarchical structure in the MFP 1 in the initial state according to the embodiment.

The multifunction device 1 has a large number of setting items, and various settings can be made. In the following description, a setting operation for printing a network status report will be described as an example, and description of other setting items will be omitted. However, the description of the setting operation for printing the network status report applies to the other setting items as well.

First, the network status report is a printed matter on which the state of the MFP 1 relating to network communication is written. Network status information i11 for printing the network status report is stored in the HDD 19b of the multi-function peripheral storage unit 19 (see FIG. 5). The network status report includes information such as the IP address of the multifunction device 1, the subnet mask address, the default gateway, communication firmware version information, the MAC address of the communication unit, and communication settings. A service person or an administrator of the multifunction device 1 can obtain detailed information regarding communication of the multifunction device 1 by looking at the network status report, which is useful for maintenance.

Next, an example of a setting operation for printing a network status report will be described with reference to FIG. Here, in the MFP 1 according to the present embodiment, the display on the display unit 1a such as the hierarchical structure and display contents can be changed by the definition file 8 (details will be described later). FIG. 7 illustrates a setting operation in the initial state (default state, state at the time of shipment) before the change.

To print the network status report, press the system menu key 1e in the function selection key group 1d. Thereby, the system menu screen S1 shown on the upper side of FIG. 7 is displayed. In other words, when the system menu key 1e is pressed, the main control unit 10 causes the display unit 1a to display the system menu screen S1 based on the display firmware F14 and the display data D1.

A plurality of keys (images for selecting setting items) are arranged on the system menu screen S1. In other words, each setting item is classified in advance, and a plurality of keys for selecting a desired setting item are arranged on the system menu screen S1. Among the plurality of keys, the user touches the display position of the key to which the screen to be called belongs.

To print the network status report, it is necessary to touch the display position of the report key K1. When the main control unit 10 recognizes that the display position of the report key K1 is touched based on the output of the touch panel unit 1b, the main control unit 10 displays the report print setting screen S2 on the display unit 1a based on the display firmware F14 and the display data D1. Display. The report print setting screen S2 is hierarchically lower than the system menu screen S1.

In the report print setting screen S2, a status page print key K2, a network report print key K3, a font list print key K4, and a service status print key K5 are arranged. To print the network status report, the user touches the display position of the network report print key K3.

The status page print key K2 is for printing a status report including status information i12 indicating the state of the multifunction device 1 (such as the installed optional device and firmware version information). The status information i12 is stored in the multifunction device storage unit 19 (HDD 19b).

The font list print key K4 is for printing a list of fonts stored in the multi-function peripheral storage unit 19 (HDD). Various fonts and information necessary for printing the font list (font data i13) are stored in the multi-function peripheral storage unit 19 (HDD 19b).

The service status print key K5 is used to print a service status report including information related to maintenance of the multifunction machine 1 (cumulative number of printed sheets, accumulated operation time of the printing unit, toner remaining amount information, etc.). The service status information i14 necessary for printing the service status report is stored in the multi-function peripheral storage unit 19 (HDD 19b).

Thus, the display on the display unit 1a has a hierarchical structure. In order to reach the target item, the user repeats the setting operation on the operation panel 11 and switches the screen to be displayed from the upper layer to the lower layer on the display unit 1a. In response to a setting operation on the operation panel 11, the main control unit 10 finally displays a setting screen on which a key for setting a setting value is arranged on the display unit 1a.

Specifically, the hierarchical structure in printing the network status report will be described with reference to FIG. As shown in FIG. 8, in order to print the network status report, first, the user presses the system menu key 1e (selects a function), the system menu screen S1, the copy main screen (corresponding to the copy function). The system menu screen S1 is selected from the uppermost setting screen such as the transmission main screen (corresponding to the transmission function). Thereby, the system menu screen S1 is displayed (first rank). Then, the user performs a setting operation on the report key K1. Thereby, the report print setting screen S2 is displayed (second hierarchy). Subsequently, the user operates the network report print key K3 on the displayed report print setting screen S2.

When an instruction to print a network status report is given (when the display position of the network report print key K3 is touched), the main control unit 10 performs processing related to printing of the network status report in the firmware F1. Then, the main control unit 10 reads the network status information i11 from the HDD 19b according to the definition content of the process. Then, the main control unit 10 causes the printing unit 13 to print a network status report using the read network status information i11.

(Hierarchical structure in the initial state of printer 2)
Next, a hierarchical structure in the display of the printer 2 in the initial state will be described with reference to FIGS. FIG. 9 is an enlarged view of the operation panel 21 portion of the printer 2. FIG. 10 is a diagram for explaining a hierarchical structure of display in the printer 2 in the initial state according to the embodiment.

The printer 2 also has a number of setting items and can perform various settings. However, in the following description, similarly to the description of the multi-function device 1, a network status report print setting operation will be described as an example. Description of other setting items is omitted. However, the description of the setting operation of the network status report in the printer 2 applies similarly to the other setting items.

The network status report printed by the printer 2 has the same information (printer 2 IP address, subnet mask address, default gateway, communication firmware version information, etc. Information such as the MAC address of the communication unit and settings related to communication). The network status information i21 for printing the network status report is stored in the HDD 29b of the printer storage unit 29 (see FIG. 6).

Next, an example of a setting operation for printing a network status report with the printer 2 will be described with reference to FIGS. Here, in the printer 2 of the present embodiment, the display on the display unit 2a such as the hierarchical structure and display contents can be changed by the definition file 8 (details will be described later). However, what will be described with reference to FIG. 9 is a setting operation in an initial state (default state, state before shipment) before the display is changed.

First, the operation panel 21 of the printer 2 will be described with reference to FIG. The operation panel 21 of the printer 2 is simplified as compared with that of the multifunction device 1, the display unit 2a is smaller than that of the multifunction device 1, and the number of hard keys is also small.

First, on the upper side of the operation panel of the printer 2, three indicators 2c are arranged. Below these indicators 2c, a display unit 2a for displaying a character string (letters and symbols such as alphabets) is arranged. A plurality of hard keys are arranged below the display unit 2a. Of the hard keys 2b, keys (circular keys 2d) with arrows in four directions (up, down, left, and right) are keys used for selecting setting items and setting setting values.

To print a network status report with the printer 2, press the “△ (up)” or “▽ (down)” of the circular key 2d until the character string “Devicecommom” is displayed on the display unit 2a. When a character string to be selected to reach the target setting item (a character string “Devicecommom”) is displayed, a hierarchy is selected by a predetermined setting operation such as pressing the right side of the circular key 2d. be able to. When an operation for selecting a setting item “Devicecommom” as a setting item is performed, the printer control unit 20 additionally displays a symbol such as “>” such as “> Devicecommom>”, and the Devicecommom hierarchy is displayed. The selection is displayed on the display unit 2a.

Next, press the “△ (UP)” or “▽ (DOWN)” of the circular key 2d again until the character string “NETWORK” is displayed on the display unit 2a. When a character string to be selected for reaching the target setting item (a character string of “network”) is displayed, the item (hierarchy) being displayed can be selected by a predetermined setting operation. At this time, the printer control unit 20 causes the display unit 2a to display that the setting item (hierarchy) of “network” among the setting items included in Devicecommom is selected, such as “> Devicecommom> Network>”. .

Subsequently, until the character string “network status report” is displayed on the display unit 2a, the “△ (up)” or “▽ (down)” of the circular key 2d is pressed again. When a character string to be selected (a character string of “network status report”) is displayed, a setting item (hierarchy, setting item) being displayed can be selected by a predetermined setting operation. At this time, the printer control unit 20 indicates that the “network status report” item (hierarchy) is selected from a plurality of setting items included in the network, such as “>> network status report”. To display. A network status report is printed by pressing a key (for example, the lower right or lower left key of the circular key 2d) instructing execution among the hard keys of the operation panel 21.

Thus, the display of the display unit 2a of the printer 2 has a hierarchical structure as well. The user repeats the setting operation on the operation panel 21. Thereby, the character string (hierarchy name) displayed on the display unit 2a is switched from the upper layer toward the lower layer. In response to a setting operation on the operation panel 21 (hard key), the printer control unit 20 causes the display unit 2a to display a character string indicating a setting item or setting value intended by the user.

Specifically, the hierarchical structure in printing a network status report will be described with reference to FIG. As shown in FIG. 10, in order to print a network status report, the setting item (character string) of “Devicecommom” is selected from among a plurality of types of setting items by setting the circular key 2d (first). Rank). Then, the setting operation is performed on the circular key 2d, and the setting item “network” is selected from the setting items included in “Devicecommom” (second rank). Subsequently, among the setting items included in “network”, the setting item (third rank) of “network status report” is selected.

When the network status report is instructed to print (when a hard key for instructing execution of printing is pressed in a state where the network status report is displayed), the printer control unit 20 uses the network in the firmware F2. Performs processing related to status report printing. Then, the printer control unit 20 reads the network status information i21 from the HDD 29b in accordance with the process definition content. Then, the printer control unit 20 uses the read network status information i21 to print or display information related to the communication of the printer 2.

(Display change on printer 2 using definition file 8)
Next, display change in the printer 2 using the definition file 8 will be described with reference to FIG. FIG. 11 is an explanatory diagram of display change in the printer 2 according to the present embodiment.

For example, when an image forming apparatus such as the printer 2 is newly installed in the office, each user has to get used to the setting operation of the newly installed image forming apparatus. Until it gets used, it is necessary to select a desired setting item or setting value through trial and error. Different types of image forming apparatuses of the same manufacturer may be equipped with similar functions and setting items (for example, printing of the network status report described above).

However, not only among other companies, but also in the same manufacturer, the hierarchical structure of the display differs depending on the type of image forming devices such as multifunction devices, printers and fax machines, the price range of image forming devices, and the release date. There is a case. For this reason, conventionally, it is not possible to perform a setting operation for a newly installed image forming apparatus with the same operation procedure as that of an image forming apparatus familiar with the setting operation. In addition, the setting operation of a new image forming apparatus may be performed in a manner confused with the operation procedure of the image forming apparatus familiar with the setting operation. As described above, since the display hierarchical structure (display order and display position of setting items) is different between the old and new, the setting operation of the image forming apparatus may be difficult to understand.

In order to change the hierarchical structure of the display, it is common to update the firmware incorporated in the image forming apparatus. However, in general, updating firmware is not as easy as creating new firmware, testing newly created firmware, rebuilding firmware, or installing new firmware on an image forming device. .

Therefore, in the printer 2 according to the present embodiment, the definition file 8 created by the user is downloaded, and the character string displayed on the display unit 2a can be changed based on the definition file 8. Thereby, the hierarchical structure in the display can be changed.

The definition file 8 is stored in the HDD 29b (see FIG. 6). The definition file 8 is acquired by reading from the storage medium 7 connected to the printer 2. Specifically, the user creates the definition file 8 using a computer, a portable information terminal (for example, a tablet terminal or a smartphone), etc., so that the display is made with a desired character string or hierarchical structure. Then, the user stores the created definition file 8 in the storage medium 7 (see FIG. 4). Subsequently, the user connects (inserts) the storage medium 7 storing the definition file 8 to the acquisition unit 28. When the acquisition unit 28 recognizes the connection of the storage medium 7, the printer control unit 20 reads the definition file 8 stored in the storage medium 7 and stores it in the HDD 29b.

Note that the communication unit 210 of the printer 2 and the computer or portable information terminal may be communicably connected by wireless communication or wired communication. Accordingly, the printer control unit 20 may download the definition file 8 and store it in the HDD 29b by communication not via the storage medium 7. In addition, setting operation of the operation panel 21 is performed to copy the definition file 8 in the initial state or the definition file 8 after the change to the storage medium 7 via the acquisition unit 28 or to the computer 5 via the communication unit 210. It can also be sent.

In this way, the definition file can be acquired by the printer. The user can create the definition file 8 so that the part whose display is to be changed is modified, and install the created definition file 8 in the HDD 29b of the printer 2 again.

Next, the definition file 8 on the left side of the definition file 8 shown in FIG. 11 is the definition file 8 in the initial state of the printer 2. The definition file 8 in the initial state is stored in advance in the printer storage unit 29 (HDD 29b) of the printer 2.

Among the definition files 8 shown in FIG. 11, the definition file 8 on the right side is a definition file 8 after being changed by the user. The definition file 8 after the change is also read from the storage medium 7 by the acquisition unit 28 and stored in the printer storage unit 29 (HDD 29b) of the printer 2.

The definition file 8 defines a plurality of combinations of character strings such as hierarchical names, setting item names, and setting value names displayed on the printer 2 and identification numbers assigned to the character strings. . In other words, the definition file 8 can be said to be a library that is dynamically linked to the display firmware F22.

When switching the display of the display unit 2a according to the setting operation for the circular key 2d, the printer control unit 20 executes a corresponding process (function, command, routine, etc.) in the display firmware F22. For example, each process included in the display firmware F22 defines an identification number corresponding to a character string (hierarchy name, setting item name) to be read from the printer storage unit 29 (HDD 29b) in the display data D2. . Then, the printer control unit 20 reads a character string corresponding to the identification number defined in the process to be executed in the definition file 8. Then, the printer control unit 20 displays the read character string on the display unit 2a as a hierarchy name or a setting item name.

This will be described with reference to the example of FIG. In the definition file 8 before the change (for example, in the initial state), the character string corresponding to “identification number 10000” is defined as “Devicecommom”. When the user performs a setting operation for displaying the character string “identification number 10000” on the circular key 2d, the printer control unit 20 displays “Devicecommom” on the display unit 2a based on the definition file 8 in the initial state. "Is displayed.

On the other hand, in the definition file 8 after the change, the character string corresponding to the “identification number 10000” is changed to the “system menu” similar to that of the multifunction machine 1. For this reason, when the user performs a setting operation for displaying the character string of “identification number 10000” on the circular key 2d, the printer control unit 20 displays the “2” on the display unit 2a based on the definition file 8 after the change. The character string of “System Menu” is displayed. In this way, the character string to be displayed on the printer 2 can be changed using the definition file 8.

Furthermore, in the definition file 8 before the change, the character string corresponding to “identification number 10001” located one layer below “identification number 10000 (character string of Devicecommom)” is defined as “network”. When the user performs a setting operation for displaying the character string “identification number 10001” on the circular key 2d, the printer control unit 20 displays “network” on the display unit 2a based on the definition file 8 in the initial state. The character string of is displayed.

On the other hand, in the definition file 8 after the change, the character string corresponding to “identification number 10001” is defined as “report”. When the user performs a setting operation for displaying the character string “identification number 10001” on the circular key 2d, the printer control unit 20 displays “report” on the display unit 2a based on the definition file 8 after the change. The character string of is displayed.

In the definition file 8 before the change, the character string corresponding to the “identification number 10002” of the character string arranged one layer below the “identification number 10001 (network)” is defined as “network status report”. . When the setting operation for displaying the character string “identification number 10002” is performed on the circular key 2d by the user, the printer control unit 20 displays “network” on the display unit 2a based on the definition file 8 in the initial state. Display the status report text.

On the other hand, in the definition file 8 after the change, the character string corresponding to “identification number 10002” is defined as “network status insert”. When the user performs a setting operation for displaying the character string “identification number 10002” on the circular key 2d, the printer control unit 20 displays “network” on the display unit 2a based on the definition file 8 after the change. The character string “Status Insatsu” is displayed.

In this way, the character strings displayed as setting items and hierarchical names on the printer 2 can be changed in the definition file 8. Thereby, without updating the firmware, the hierarchical structure and the hierarchical name in the display of the printer 2 can be changed so that the user can easily understand the setting operation (so that the user can easily reach the desired hierarchical level).

In operating the printer 2, the ROM 29a of the printer storage unit 29 stores the firmware F2. In the firmware F2, identification numbers are assigned to the included processes. In other words, the printer storage unit 29 stores firmware F2 for operating the printer 2 and processing firmware F23 with an identification number. Regarding the printing of the network status report, the ROM 29a stores the processing firmware F23 that operates the printing unit 22 and controls the printing unit 22 to print the network status report. The HDD 29b stores a definition file 8 in which a combination of a character string and an identification number to be displayed for printing a network status report is defined.

When the printer control unit 20 receives an instruction to execute a function included in the embedded system 100 from the operation panel, the printer controller 20 attaches the same identification number as the identification number of the character string corresponding to the function for which the execution instruction has been made. The processed process (processing firmware F23) is executed.

As an example of printing a network status report, “Network Status Report” is displayed before the definition file 8 is changed, and “Network Status / Insert” is displayed after the definition file 8 is changed. When the hard key 2b for instructing execution of the network status report is pressed, the printer control unit 20 corresponds to the identification number “10002” of these character strings in the processing firmware F2 of the ROM 29a (the same identification number is A “network status report printing” process is executed, and the printing unit 22 is caused to print the network status report.

In this way, even if the definition file 8 is changed, the link between the character string (identification number) in the definition file 8 and the corresponding firmware (processing firmware F23) before and after the change. Is maintained. Therefore, the function cannot be used because the display on the display unit 2a is changed.

(Display change on MFP 1 using definition file 8)
Next, a display change in the multifunction machine 1 using the definition file 8 will be described with reference to FIGS. 7, 12, and 13. FIG. 12 is an explanatory diagram of display change in the multifunction machine 1 using the definition file 8 according to the present embodiment. FIG. 13 is a diagram illustrating an example of a printing procedure of the network status report after the display change by the definition file 8.

10 and 11, the example in which the character string displayed on the printer 2 is changed and the hierarchical structure is changed by the definition file 8 has been described. However, not only the printer 2 but also the multifunction device 1 of the present embodiment can change the displayed character string (hierarchy name or setting item name) to change the hierarchical structure. Hereinafter, the display change in the multifunction machine 1 will be described.

In the multifunction device 1, the definition file 8 is stored in the HDD 19b. The definition file 8 is acquired by reading from the storage medium 6 (see FIG. 2) connected to the multifunction device 1. Specifically, the user creates the definition file 8 using a computer, a portable information terminal (for example, a tablet terminal or a smartphone), etc., so that the display is made with a desired character string or hierarchical structure. Then, the user stores the created definition file 8 in the storage medium 6. Subsequently, the user connects (inserts) the storage medium 6 storing the definition file 8 to the acquisition unit 111. When the acquisition unit 111 recognizes the connection of the storage medium 6, the main control unit 10 reads the definition file 8 stored in the storage medium 7 and stores it in the HDD 29 b. As in the case of the printer 2, the definition file 8 may be downloaded to the communication unit 43 of the multifunction machine 1 and stored in the HDD 19b by wireless communication or wired communication.

Next, the definition file 8 stored in the multifunction machine 1 will be described with reference to FIG. The definition file 8 on the left side of the definition file 8 shown in FIG. 12 is the definition file 8 of the multifunction device 1 before change (for example, in an initial state). The definition file 8 before the change is stored in advance in the multifunction device storage unit 19 (HDD 19b) of the multifunction device 1.

The definition file 8 on the right side of the definition file 8 shown in FIG. 12 is the definition file 8 after the change in which the user has changed the definition file 8 before the change. The definition file 8 after the change is also read from the storage medium 6 by the acquisition unit 111 and stored in the multifunction device storage unit 19 (HDD 19b) of the multifunction device 1.

The definition file 8 of the multifunction device 1 also defines a plurality of combinations of character strings such as hierarchy names, setting items, and setting values displayed on the multifunction device 1 and identification numbers assigned to the character strings. ing. In other words, even in the multi function device 1, the definition file 8 can be said to be a library that is dynamically linked to the display firmware F14.

When the display of the display unit 1a is switched according to the setting operation on the keys and hard keys in the setting screen displayed on the display unit 1a, the main control unit 10 displays a new setting screen in the display firmware F14. Processing (functions, instructions, routines) is executed. For example, in each process included in the display firmware F14, an identification number corresponding to a character string (hierarchy name, setting item name) read from the storage unit (HDD 19b) is defined. The main control unit 10 reads from the HDD 19b the character string corresponding to the identification number defined in the process to be executed in the definition file 8 and the image data necessary for displaying the setting screen. The main control unit 10 displays the read character string on the display unit 2a as a hierarchy name or a setting item name.

This will be described with reference to the example of FIG. In the definition file 8 before the change (for example, in the initial state), the character string corresponding to “identification number 10000” is defined as “system menu”. When the user performs a setting operation for displaying the character string of “identification number 10000” (pressing the system menu key 1e), the main control unit 10 displays the definition file 8 in the initial state on the display unit 1a. A system menu screen S1 (see FIG. 8) including the character string “system menu” is displayed.

On the other hand, in the definition file 8 after the change, the character string corresponding to the “identification number 10000” is changed to “Devicecommom” similar to the printer 2. Therefore, when the user performs a setting operation to display the character string “identification number 10000”, the main control unit 10 displays the character string “Devicecommom” on the display unit 1a based on the definition file 8 after the change. A setting screen is displayed (see the upper side of FIG. 13, and the changed portion is indicated by a solid arrow).

Furthermore, in the definition file 8 before the change, the character string corresponding to “identification number 10001” positioned one layer below “identification number 10000 (character string of Devicecommom)” is defined as “report”. When the user performs a setting operation for displaying the character string “identification number 10001” (touching the display position of the report key K1), the main control unit 10 displays the display unit based on the definition file 8 in the initial state. A report print setting screen S2 including the character string “Report” is displayed on 1a (see FIG. 8).

On the other hand, in the definition file 8 after the change, the character string corresponding to “identification number 10001” is defined as “network”. When the user performs a setting operation to display the character string “identification number 10001”, the main control unit 10 includes the character string “network” in the display unit 1 a based on the definition file 8 after the change. A setting screen is displayed (refer to the lower diagram of FIG. 13, the changed portion is indicated by a solid arrow).

In addition, the character string of “report” (the character string of the setting item) given in the report key K1 is displayed in the upper diagram of FIG. As shown, it may be replaced with “network”.

And on the setting screen, a network report print key K3 is arranged. The character string (character string corresponding to “identification number 10003”) arranged in the network report print key K3 before and after the change is the same as “print” so that there is no change in the definition file 8. . Before the change, the character string of “network status” (character string indicating the setting item, character string corresponding to “identification number 10002”) attached to the network report print key K3 is shown in the lower diagram of FIG. As shown in FIG. 4, it may be replaced with “network report”.

As described above, by changing the character string indicating the setting item name and the hierarchy name in the definition file 8, the user can perform the setting according to the flow and the hierarchical structure similar to the setting operation in the printer 2. As shown in FIG. 13, the display on the multi-function device 1 is brought close to the display of the hierarchical structure of the printer 2, so that the user who is used to the print setting operation of the network status report on the multi-function device 1 can easily use the multi-function device 1. You can print a network status report.

Thereby, without updating the firmware, it is possible to change the hierarchical structure and the hierarchical name in the display of the multifunction machine 1 so that the user can easily understand the setting operation (so that the user can easily reach the desired hierarchical level). .

The ROM 19a of the multifunction device storage unit 19 stores firmware F1 for operating the multifunction device 1. Also in the firmware F1, identification numbers are assigned to the included processes. In other words, the storage unit 1 stores the firmware F1 for operating the multifunction device 1 and the processing firmware F15 with the identification number. Regarding the printing of the network status report, the ROM 19a of the multi-function peripheral storage unit 19 stores the processing firmware F15 whose contents cause the printing unit 13 to operate and control the printing unit 13 to print the network status report. The HDD 19b stores a definition file 8 in which a combination of a character string and an identification number to be displayed for printing a network status report is defined.

When the main control unit 10 receives an instruction to execute a function included in the embedded system 100 via the operation panel 11, the main control unit 10 has the same identification number as the character string corresponding to the function for which the execution instruction has been made in the processing firmware F1. The process with the identification number is executed.

For example, in printing a network status report, when the display position of the network report print key K3 including the character string “print” is touched on the report print setting screen S2 (when execution of printing of the network status report is instructed) The main control unit 10 performs processing corresponding to the identification number “10003” of the character string “print” in the processing firmware F15 of the ROM 19a (the same identification number is assigned) “print network status report”. The process is executed to cause the printing unit 13 to print a network status report.

Thus, even if the definition file 8 is changed, the link between the character string (identification number) in the definition file 8 and the corresponding firmware (processing firmware F15) is maintained. Therefore, the function cannot be disabled by changing the display on the display unit 1a.

(Flow of display based on definition file 8)
Next, a display flow based on the definition file 8 in the image forming apparatus (multifunction device 1 and printer 2) according to the present embodiment will be described with reference to FIG. FIG. 14 is a flowchart showing a display flow based on the definition file 8 in the image forming apparatus according to the present embodiment.

The start of FIG. 14 is to supply power to the operation panel (operation panel 11, operation panel 21) when the main power of the image forming apparatus (multifunction device 1, printer 2) is turned on or when the power saving mode is returned to the normal mode. Is started and display on the operation panel is started.

First, the control unit (main control unit 10 and printer control unit 20) reads the definition file 8 stored in the storage unit (multifunction machine storage unit 19 and printer storage unit 29) into the RAM, and based on the definition file 8, An upper layer screen is displayed (step # 1). Then, the control unit confirms whether or not an instruction to execute a function (job) such as printing of a network status report has been issued (step # 2).

When an instruction to execute a function (job) is issued, the control unit (main control unit 10 and printer control unit 20) uses firmware with the same identification number as the character string identification number of the function (job) for which execution has been instructed. The processing in (firmware F1, firmware F2) is executed (step # 3). When the process is executed, the control unit displays the screen of the highest layer on the display unit (display unit 1a, display unit 2a) from the standpoint of the set of hierarchical positions (step # 4).

On the other hand, when the execution instruction of the function (job) is not made (No in Step # 2) and after Step # 4, the control unit (main control unit 10 and printer control unit 20) displays an operation panel (operation panel). 11, the operation panel 21) is operated to set the content for switching the display, and it is confirmed whether or not it is necessary to switch the display (whether or not a new setting screen or character string needs to be displayed) ( Step # 5). The control unit determines whether or not to switch the display based on whether or not the display position of the key is touched based on the touch panel unit 1b and whether or not the setting operation to the hard key is performed.

If an operation is performed and there is no need to switch the display (No in step # 5), the control unit (main control unit 10, printer control unit 20) stores the memory card in the acquisition unit (acquisition unit 111, acquisition unit 28). It is confirmed whether or not a storage medium such as is connected (step # 6). If it is connected (Yes in Step # 6), the control unit reads the definition file 8 from the storage medium, stores it in the storage unit (multifunction device storage unit 19 or printer storage unit 29), and acquires it (after change). To the definition file 8) (step # 7). If the storage medium is not connected to step # 7 (No in step # 6), the flow returns to step # 2.

If the operation is performed and it is necessary to switch the display (Yes in step # 5), the control unit responds to the setting operation performed based on the firmware (display firmware F14, display firmware F22) and the definition file 8. The display is performed on the display unit (display unit 1a, display unit 2a) (step # 8). If the definition file 8 is changed, the character string changed in the definition file 8 is displayed. Then, the flow returns to step # 2.

Note that this flow is before the transition to the power saving mode or before the main power is turned off, and continues while the display on the display unit is being performed and power is being supplied to the control unit and the acquisition unit.

In this way, the embedded system 100 (multifunction device 1 and printer 2) of the present embodiment receives a setting input based on the display unit (display unit 1a, display unit 2a) that displays settings and the display on the display unit. An acquisition unit (acquisition unit 111) that acquires an input unit (touch panel unit 1b, hard key 1c, circular key 2d, hard key 2b, and the like) to be received and a definition file 8 for defining display contents related to display unit settings. , An acquisition unit 28), display firmware (display firmware F14, display firmware F22) for causing the display unit to display settings, and a storage unit (multifunction device storage unit) that stores the acquired definition file 8 19, the printer storage unit 29), the display firmware and the setting operation performed on the input unit based on the acquired definition file 8 Depending on the content, including a display unit, a processing unit to perform the display of the defined hierarchy definition file 8 (the main control unit 10, the printer control unit 20), the.

Thereby, it is possible to display on the display unit (display unit 1a, display unit 2a) in a manner in accordance with the definition in the definition file 8. In other words, the user can change the display on the embedded system 100 (multifunction device 1, printer 2) according to the user's desire by creating the definition file 8 so that the display is performed in a desired manner. Can do. Therefore, the hierarchical structure in the display can be changed so as to be easily understood by the user. Therefore, it is possible to change the hierarchical structure in the display of the embedded system 100 and change the display contents, which were difficult in the past, without updating the firmware. Then, the display on the embedded system 100 can be changed so that the display is similar to or similar to the embedded system 100 that the user is familiar with. Therefore, the display on the new embedded system 100 can be customized so that the operation procedure becomes easy to understand and approaches the familiar embedded system 100.

Conventionally, by changing the display of items and keys (buttons) for instructing execution of a function, the link with the corresponding function is broken, and the function whose display has been changed may not be usable. Therefore, the storage unit (multifunction machine storage unit 19 or printer storage unit 29) defines the processing firmware in which the identification number is assigned to the included process and the definition file 8 in which the identification number corresponding to the character string to be displayed is defined. The processing unit (main control unit 10 and printer control unit 20) has an input unit (touch panel unit 1b, hard key 1c, circular key 2d, hard key 2b, etc.) embedded system 100 (multifunction device 1, printer 2). When the execution instruction of the function included in () is received, the process having the same identification number as the identification number of the character string corresponding to the function for which the execution instruction is made is executed in the processing firmware.

This enables to maintain the link between the changed part and the process in the firmware for executing the function even if the display of the part instructing the execution of the function is changed. Therefore, the embedded system 100 (multifunction machine 1, printer 2) can be operated without any problem.

Further, it includes a printing unit (printing unit 13, printing unit 22) for printing a report related to the embedded system 100 (multifunction device 1, printer 2), and a storage unit (multifunction device storage unit 19, printer storage unit 29) includes a report. A processing firmware including processing for printing, a definition file 8 in which a combination of a character string displayed to instruct execution of report printing and its identification number is defined, and a processing unit (main control unit) 10. When the input unit (touch panel unit 1b, hard key 1c, circular key 2d, hard key 2b, etc.) receives the report print execution instruction, the printer control unit 20) prints the report out of the processing firmware. The process with the same identification number as that of the character string is executed, and the report is printed on the printing unit.

This maintains the link between the part where the display is changed and the firmware for printing the report, even if the hierarchical structure or the name of the displayed key is changed. Thus, the report can be printed without any problem on the embedded system 100 (multifunction device 1, printer 2) without changing the firmware.

The definition file 8 defines a character string indicating the layer name of each layer in the display hierarchical structure. The processing unit (the main control unit 10 and the printer control unit 20) defines the layer name defined in the definition file 8. Is displayed in the corresponding hierarchy.

Thus, by creating the definition file 8 so that the setting operation similar to that of the embedded system 100 (multifunction device 1, printer 2) familiar with the setting operation can be performed, even in a new embedded system, the target can be obtained without hesitation. It is possible to reach a hierarchy, and a desired setting can be easily performed. Accordingly, the user can easily understand the operation procedure.

The definition file 8 defines setting item names in the display hierarchical structure, and the processing units (main control unit 10 and printer control unit 20) use the setting item names defined in the definition file 8 as setting items. Display to select,

First, in order to reach the screen for setting a desired setting item (function), it is usually necessary to press a key one or more times. In the definition file 8, for example, the setting item name is defined so that it is displayed with the same name as the familiar embedded system 100 (multifunction device 1, printer 2). As a result, in the same manner as the embedded system 100 familiar with the setting operation, by performing the setting operation, the target setting item can be reached and the setting item can be set.

The acquisition unit (acquisition unit 111, acquisition unit 28) acquires the definition file 8 from the connected portable storage medium, and the storage unit (multifunction device storage unit 19, printer storage unit 29) Based on the acquired definition file 8, the definition file 8 is updated.

Thus, the definition file 8 created by the user can be easily stored in the embedded system 100 (multifunction machine 1, printer 2, image forming apparatus) from a storage medium such as a memory card or an external HDD.

Further, the image forming apparatus includes the above-described embedded system 100 (multifunction machine 1, printer 2). Accordingly, an image forming apparatus capable of easily changing the screen displayed by the embedded system 100 (image forming apparatus) based on the firmware and the hierarchical structure of the display without recompiling (building) the compile or linking. Can be provided.

In the above description, the MFP 1 is taken as an example of the embedded system 100, but the present invention can also be applied to an embedded system 100 (image forming apparatus) such as a copying machine or a FAX apparatus.

Moreover, although the embodiment of the present invention has been described, the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.

The present invention can be used in an embedded system such as an image forming apparatus including an operation panel.
