  The scanning unit 31 outputs document image data by executing the image reading process. The scan control unit 3 controls the scan unit 31 to transfer the document image data to other devices such as the image processing unit 5 through the bus 9.

  The image forming unit 41 executes the image forming process by a known electrophotographic method or ink jet method. The image forming control unit 4 controls the image forming unit 41 to cause the image forming unit 41 to execute the image forming process.

  In the image forming process, the image forming control unit 4 acquires raster data from the image processing unit 5 and causes the image forming unit 41 to execute a process for forming an image based on the raster data on the sheet.

  The communication unit 6 transmits / receives data to / from an external device via the network 101. The external device is an information terminal such as another image forming apparatus 10 or a personal computer (not shown).

  Further, the communication unit 6 exchanges data with other devices through the bus 9. For example, the communication unit 6 receives print job data from the external device, and transfers the print job data to the image processing unit 5 through the bus 9.

  The communication unit 6 also has a function of acquiring the document image data from the scan control unit 3 via the image processing unit 5 and transmitting the data to the external device.

  The image processing unit 5 executes various data processing on image data obtained from other devices via the bus 9. The target of data processing by the image processing unit 5 is, for example, the document image data obtained from the scanning unit 31 or the print job data obtained from the external device through the communication unit 6.

  For example, the image processing unit 5 performs image processing such as image rotation processing, halftone processing, or size cut processing on the document image data obtained from the scan control unit 3. The image processing unit 5 also executes processing for converting the document image data and the print job into the raster data and transferring the raster data to the image formation control unit 4.

  The storage media interface 7 is an interface to which the storage media 8 is detachably attached. The main control unit 1 can write data to the storage medium 8 and read data from the storage medium 8 through the storage medium interface 7. The storage medium 8 is, for example, a USB memory or an SD memory card (SD is a registered trademark of the SD card association).

  As shown in FIG. 2, the operation display unit 2 includes an operation unit 21 and a display unit 22. The operation unit 21 includes a touch panel and operation buttons. The display unit 22 is a panel type display unit such as a liquid crystal display panel. The touch panel is formed on the surface of the display unit 22. The operation unit 21 receives an operation corresponding to the operation icon displayed on the display unit 22.

  The main control unit 1 controls the other control units in an integrated manner. For example, the main control unit 1 displays a setting screen g1 related to image formation on the display unit 22 (see FIG. 7). Further, the main control unit 1 controls other control units according to input information input through operations on the operation unit 21 and detection results of various sensors.

  As shown in FIG. 1, the main control unit 1 includes an MPU (Micro Processor Unit) 11 and a data storage unit 12.

  The MPU 11 is a processor that executes various operations and data processing. The data storage unit 12 is a computer-readable non-volatile storage unit that stores various types of information referred to by the MPU 11. The data storage unit 12 is also a storage unit that can read and write various information by the MPU 11.

  The data storage unit 12 stores programs for causing the MPU 11 to execute various processes, information referred to by the MPU 11 that executes these programs, and information to be written.

  For example, the data storage unit 12 stores authentication data D0, a screen customization file D1, a backup file D2, and the like.

  The authentication data D0 is data including information for uniquely specifying each user who can use the image forming apparatus 10. The authentication data D0 is, for example, a user ID and a password, and is referred to in the authentication process for permitting the use of the image forming apparatus 10.

  When the image forming apparatus 10 is energized, the MPU 11 first executes the authentication process. The authentication process is a process for determining the success or failure of authentication by comparing the authentication input information with the information of the authentication data D0 stored in the data storage unit 12 in advance. The authentication input information is input through the operation unit 21 of the operation display unit 2 or another information input unit.

  The authentication process is realized by the MPU 11 executing the user authentication program Pr1.

  For example, the MPU 11 displays a login screen (not shown) on the display unit 22 and acquires the authentication input information through the operation unit 21. Further, the MPU 11 collates the authentication input information with the information of the authentication data D0 stored in the data storage unit 12 in advance.

  If the authentication input information matches the authentication data D0 information, the authentication is successful. Otherwise, the authentication fails.

  Note that it is conceivable that the MPU 11 inputs the user's biological information as the authentication input information through the biological information input device. In this case, the image forming apparatus 10 includes the biological information input device such as a fingerprint reading sensor that reads fingerprint information or a camera that takes a face image.

  In the image forming apparatus 10, the main control unit 1, the operation display unit 2, the communication unit 6, and the storage media interface 7 have the information processing apparatus 100 that executes processing for displaying the setting screen g 1 on the display unit 22 and processing related thereto. It is composed.

  As shown in FIG. 7, in the image forming apparatus 10, a setting screen g <b> 1 including an operation icon g <b> 11 that specifies the conditions for the image forming process is displayed on the display unit 22. The operation unit 21 receives an operation corresponding to the operation icon g <b> 11 displayed on the display unit 22 of the information processing apparatus 100.

  The conditions of the image forming process designated by the operation of the operation icon g11 include various conditions. For example, the condition of the image forming process includes a condition for designating whether the image forming surface is one side or both sides of the sheet. The image forming process condition includes a condition for designating whether the output image is a color image or a monochrome image. The image forming process condition includes a condition for designating the image quality of the output image. The image forming process conditions include a condition for designating the sheet size and a condition for designating a reduction ratio or enlargement ratio of the output image.

  Then, the image forming unit 41 executes the image forming process according to the conditions specified by the operation on the operation icon g11. The operation icon g11 is an example of a display item displayed on the display unit 22.

  By the way, if the user can customize the setting screen g1 of the image forming apparatus 10, the convenience of operation of the image forming apparatus 10 is enhanced. Here, it is preferable if the customization is possible without installing dedicated software on the information terminal operated by the user.

  For example, a text file including a character string representing customization information of the setting screen g1 is generated through general text editing software, and the image forming apparatus 10 displays the setting screen g1 on the display unit 22 according to the contents of the text file. It is possible.

  On the other hand, when the user arbitrarily creates the text file, misused character strings that do not follow a predetermined regular format are likely to be included in the text file. Therefore, when the text file includes the misused character string, if the image forming apparatus 10 cannot output the screen to the display unit 22, the user may not be able to use the image forming apparatus 10 and the situation may frequently occur. .

  In the image forming apparatus 10 according to the present embodiment, the screen customization file D1 is a text file including a character string representing customization information of the setting screen g1. The main control unit 1 displays the setting screen g1 on the display unit 22 according to the contents of the screen customization file D1 by executing setting screen output control described later.

  The backup file D2 is a file copied from the screen customization file D1 under a predetermined condition. In the initial state of the image forming apparatus 10, the backup file D2 is the same file as the standard screen setting file D3. The standard screen setting file D3 is a file that defines the standard setting screen g1.

  The standard screen setting file D3 and the backup file D2 having the same contents are stored in advance in the data storage unit 12 at the time of shipment of the apparatus. Details of the screen customization file D1 and the backup file D2 will be described later.

  In the setting screen output control, even when the screen customization file D1 includes a misused character string that does not conform to the regular format, the main control unit 1 makes the setting according to the intention of the creator of the screen customization file D1 as much as possible. The screen g1 can be displayed on the display unit 22.

  The screen customization file D1 is recorded in the data storage unit 12 by the MPU 11. The process of recording the screen customization file D1 in the data storage unit 12 is executed before the setting screen output control is executed.

  For example, when the storage medium 8 that stores the screen customization file D1 is attached to the storage medium interface 7, the MPU 11 reads the screen customization file D1 from the storage medium 8 and writes it to the data storage unit 12.

  When the communication unit 6 receives the screen customization file D1 from the external information terminal, the MPU 11 acquires the screen customization file D1 from the communication unit 6 and writes it to the data storage unit 12.

  In the present embodiment, the MPU 11 executes a process of writing the screen customization file D1 into the data storage unit 12 under the situation where the authentication process is successful. Then, the MPU 11 records the screen customization file D1 in the data storage unit 12 in association with the authentication data D0 in the successful authentication process.

  That is, the screen customization file D1 is stored in the data storage unit 12 for each authentication data D0 that is information for identifying each user.

[Setting screen output control]
Hereinafter, an example of the setting screen output control procedure will be described with reference to the flowchart shown in FIG. In the following description, S1, S2,... Represent identification codes of respective steps executed by the MPU 11 of the main control unit 1 in the setting screen output control.

  The MPU 11 executes the setting screen output control when the authentication process is successful. Furthermore, the MPU 11 also executes the setting screen output control when the screen customization file D1 of the data storage unit 12 is updated. The setting screen output control is realized by the MPU 11 executing the setting screen output control program Pr2.

<Process S1>
In the setting screen output control, first, the MPU 11 refers to the screen customization file D1 in the data storage unit 12. In this step, the MPU 11 determines whether or not the screen customization file D1 corresponding to the authentication data D0 of the successful authentication process exists in the data storage unit 12.

  For example, as shown in FIG. 4, the screen customization file D1 is a text file including a display designation character string Tx0. The display designation character string Tx0 is a character string that designates the operation icon g11 displayed on the display unit 22 and the display form of the operation icon g11.

  The display designation character string Tx0 includes an icon designation character string Tx1 and a display form designation character string Tx2. The icon designation character string Tx1 is a character string representing the type of the operation icon g11. The display form designation character string Tx2 is a character string representing the display form of the operation icon g11.

  The icon designation character string Tx1 and the display form designation character string Tx2 are represented according to a predetermined format. Thereby, the MPU 11 can determine the operation icon g11 to be displayed from the icon designation character string Tx1, and can further determine the display form of the operation icon g11 from the display form designation character string Tx2.

  Further, the display form designation character string Tx2 is associated with the icon designation character string Tx1 by being represented according to the predetermined style.

  The icon designation character string Tx1 shown in FIG. 4 is a character string representing an execution button icon that accepts an operation for shifting to a designated menu screen. In addition, the icon designation character string Tx1 may be a character string representing a parameter selection icon or a numerical value input icon.

  The parameter selection icon is an operation icon g11 that receives an operation of selecting one or a plurality of the parameters from a plurality of parameter selection options for the image forming process. The numerical value input icon is an operation icon g11 that receives an operation of inputting a numerical value.

  As shown in FIG. 4, the display form designation character string Tx2 includes the display position of the operation icon g11, the title displayed together with the operation icon g11, the font of the title, the display color of the title, and the display color of the operation icon g11. Or the like.

<Process S2>
When the screen customization file D1 corresponding to the authentication data D0 of the successful authentication process exists, the MPU 11 reads the screen customization file D1 from the data storage unit 12.

  The MPU 11 that executes the process of step S2 is an example of a file reading unit that reads the screen customization file D1 from the nonvolatile data storage unit 12.

<Process S3>
Furthermore, the MPU 11 executes a designated character string extraction process. The specified character string extraction process is a process of extracting the icon designating character string Tx1 in the default style representing the type of the operation icon g11 and the display format designating character string Tx2 in the default style corresponding thereto from the screen customization file D1. is there.

  In the designated character string extraction process, the MPU 11 extracts the character strings represented in accordance with the predetermined style as the icon designated character string Tx1 and the display form designated character string Tx2.

  Furthermore, in step S3, when one or both of the icon designation approximate character string Tx11 and the display form designation approximate character string Tx21 are included in the screen customization file D1, the MPU 11 also extracts the character string.

  FIG. 5 shows an example of the icon designation approximate character string Tx11, and FIG. 6 shows an example of the display form designation approximate character string Tx21.

  The icon-designated approximate character string Tx11 is a character string that satisfies an approximate condition predetermined for the icon-designated character string Tx1 in the default style and is different from the default style. Similarly, the display form designation approximate character string Tx21 is a character string that satisfies the approximation condition with respect to the display form designation character string Tx2 in the default style and is different from the default style.

  For example, it is conceivable that the approximation condition is a condition that a plurality of characters having the same arrangement order with respect to the character string in the default format are included in a predetermined ratio or more.

  In step S3, if the screen customization file D1 includes a character string that does not conform to the default format, the MPU 11 detects the character string as an error character string. Icon designation approximate character string Tx11 and display form designation approximate character string Tx21 are also examples of the error character string.

  In step S3, the MPU 11 determines whether the screen customization file D1 is a normal file or an error file. The normal file is a file from which the icon designation character string Tx1 of the default format is extracted and does not include a character string different from the default format. The screen customization file D1 shown in FIG. 4 is an example of the normal file.

  The error file is a file in which the icon designating character string Tx1 in the default format has not been extracted, or a file in which one or more error character strings have been detected. In addition, MPU11 which performs the process of process S3 is an example of a designated character string extraction part.

<Step S4>
When it is determined that the screen customization file D1 is the normal file, the MPU 11 stores the screen customization file D1 in the data storage unit 12 as the backup file D2. The MPU 11 that executes the process of step S4 is an example of a file backup unit.

<Step S5>
Furthermore, when it is determined that the screen customization file D1 is the normal file, the MPU 11 executes the first display control. The first display control is executed when the icon designation character string Tx1 in the default style and the display style designation character string Tx2 in the default style corresponding to the default style are extracted from the screen customization file D1.

  In the first display control, the MPU 11 causes the display unit 22 to display the operation icon g11 corresponding to the extracted icon designation character string Tx1 in the display form corresponding to the extracted display style designation character string Tx2.

  A setting screen g1 shown in FIG. 7 is an example of a screen on which an operation icon g11 is displayed based on the screen customization file D1 (the normal file) shown in FIG. The MPU 11 that executes the process of step S5 is an example of a first display control unit.

<Step S6>
Further, when the icon-designated character string Tx1 in the default format is extracted from the screen customization file D1, and the error character string corresponding to the icon-designated character string Tx1 is included in the screen customization file D1, the MPU 11 Execute display control.

  In the second display control, the MPU 11 displays the operation icon g11 corresponding to the extracted icon designation character string Tx1 on the display unit 22 in a predetermined error explicit form indicating a format error.

  The setting screen g1 shown in FIG. 8 is an example of the setting screen g1 displayed based on the screen customization file D1 (the error file) shown in FIG. The setting screen g1 in FIG. 8 includes an operation icon g12 displayed in the error explicit form. The operation icon g12 is an example of the display item corresponding to the display form designation approximate character string Tx21.

  The error explicit form shown in FIG. 8 is a form of blinking the operation icon g11. In addition to the example shown in FIG. 8, the error explicit form includes a form in which the operation icon g11 is displayed in a predetermined error area on the screen of the display unit 22, a form in which the operation icon g11 is highlighted, and an operation icon g11 in advance. It may be a combination of one or more of the forms that are defined and displayed in a unique color.

  By displaying the operation icon g11 in the error explicit form, the user can recognize that the screen customization file D1 includes a character string that does not conform to the default format.

  Further, also when the icon designation approximate character string Tx11 is extracted from the screen customization file D1, the MPU 11 executes the second display control. In this case, the MPU 11 displays the operation icon g11 corresponding to the extracted icon designation approximate character string Tx11 on the display unit 22 in the error explicit form.

  The setting screen g1 shown in FIG. 10 is an example of the setting screen g1 displayed based on the screen customization file D1 (the error file) shown in FIG. The setting screen g1 in FIG. 10 includes an operation icon g13 displayed in the error explicit form. The operation icon g13 is an example of the display item corresponding to the icon designation approximate character string Tx11.

  As shown in FIGS. 8 and 10, in the second display control, the MPU 11 causes the display unit 22 to display the supplement icon g14 corresponding to the operation icon g12 or g13 displayed in the error explicit form. Can be considered.

  The supplement icon g14 is an operation icon for accepting execution of an error location notification process for notifying a location that does not follow the default format in the screen customization file D1.

  FIG. 9 shows a format error location notification screen g15 displayed on the display unit 22 by the MPU 11 in the error location notification processing. The format error location notification screen g15 is a screen that displays a partial character string of the screen customization file D1 that causes the operation icon g12 to be displayed in the error explicit form.

  The user can recognize a location that does not follow the default format in the screen customization file D1 by using the format error location notification screen g15. The MPU 11 that executes the process of step S6 is an example of a second display control unit.

<Step S7>
When the icon designation character string Tx1 in the default format is not extracted from the screen customization file D1, the MPU 11 reads the backup file D2 from the data storage unit 12.

  In this embodiment, when the icon designation approximate character string Tx11 is extracted from the screen customization file D1, it is considered that the icon designation character string Tx1 has been extracted. In this case, the second display control (S6) based on the screen customization file D1 is executed.

  Then, after the process of step S7, the MPU 11 regards the backup file D2 as the screen customization file D1, and executes the processes of step S3 and step S5. Note that the process of step S4 may be executed or skipped.

  When the backup file D2 is read, the MPU 11 extracts the icon-designated character string Tx1 and the display form-designated character string Tx2 in the default format from the backup file D2 in step S3.

  Similarly, when the backup file D2 is read, the MPU 11 displays the operation icon g11 on the display unit 22 according to the icon designation character string Tx1 and the display form designation character string Tx2 extracted from the backup file D2 in step S5. Let

  Thus, the setting screen output control ends.

  According to the present embodiment, the intention of the creator of the screen customization file D1 is as much as possible even when the screen customization file D1 including the character string representing the customization information of the setting screen g1 includes a misused character string that does not conform to the regular format. Can be displayed on the display unit 22.
