  Note that in a device that performs user authentication, message data may be managed separately for each user.

  FIG. 2 shows a message change setting screen 4 a in the display unit 4.

  This message change setting screen 4a has touch keys (buttons) 11a and 11b for setting “permission” and “prohibition” for “message change”, and “input exceeding the display area”. There are keys 12a and 12b for setting “permitted” and “prohibited”.

  As for “list display unit”, there are keys 13a, 13b, 13c, and 13d corresponding to “screen”, “application (application)”, “function”, and “language”, respectively, and one of them is set. Be able to.

  In other words, whether or not "List messages on screen", "List messages used in application", "List messages used by function", "List messages used by language" Can be set by selecting the keys 13a, 13b, 13c, and 13d in units of "screen", "application", "function", and "language".

  Further, the message change setting screen 4a includes an “OK” key 14a for confirming selection of the “permitted”, “prohibited” or “screen”, “application”, “function”, and “language” keys; A “cancel” key 14b for canceling is displayed.

  FIG. 3 shows a screen 4b displayed on the display unit 4 when change permission is set on the message change setting screen 4a (FIG. 2).

  That is, in the above-described message change setting screen 4a, when the “permit” key 11a is pressed to permit message change and the “OK” key is pressed, the basic setting screen 4b which is one of the display screens in the normal display mode. Is displayed, and the [*] key P is displayed at the lower left of the screen. In the initial setting, message change is “prohibited” and the [*] key P is not displayed. That is, the [*] key is a display indicating that the message change permission state is set.

  In this basic setting screen 4b, in addition to the message “Ready to copy”, tab keys for “basic setting”, “consolidation / original”, “image quality / density”, and “application setting” are displayed. A development screen 4c showing the contents of “setting” is also displayed.

  The development screen 4c displays keys of “color”, “paper”, “magnification”, “single / double-sided”, “box save” key 16a, “continuous reading” key 16b, and “finish” key. 16c is displayed.

  Also, pressing the tab keys for “Collect / Original”, “Quality / Density”, and “Application Settings” displays the corresponding screen, and also when pressing each key such as “Color”, “Paper”, etc. The corresponding screen is displayed.

  When the [*] key P is pressed on the basic setting screen 4b of FIG. 3, the character change mode is entered, and the display unit of the list set on the message change setting screen 4a (FIG. 2), that is, “screen”, Messages are extracted in accordance with any one of “application”, “function”, and “language”, and a list of the extracted messages is displayed.

  For example, in the message change setting screen 4a (FIG. 2), when extraction in units of “screen” is set, when the [*] key P is pressed, as shown in the screen 400a of FIG. Each key of the “Basic setting screen”, “Paper selection screen”, “Aggregation / Original screen”, “Image quality / Density screen”, “Application setting screen”, “Color screen”, etc. Will be listed. When any screen key is pressed, a list of messages displayed on the screen is extracted and displayed on the display unit 4.

  In addition, in the message change setting screen 4a (FIG. 2), when extraction is set in “application” units, when the [*] key P is pressed, as shown in the screen 400b of FIG. “Copy”, “Fax”, “Scan”, and “Box” application keys are displayed. When one of the application keys is pressed, a list of messages used in the application is extracted and displayed on the display unit 4.

  Further, in the message change setting screen 4a (FIG. 2), when extraction in units of “function” is set, when the [*] key P is pressed, as shown in the screen 400c of FIG. Function keys of “user operation”, “universal”, “user assistance”, “program”, “utility”, and “administrator setting” are displayed. When one of the function keys is pressed, a list of messages used for the function is extracted and displayed on the display unit 4.

  Further, in the message change setting screen 4a (FIG. 2), when extraction in units of “language” is set, when the [*] key P is pressed, as shown in the screen 400d of FIG. Each language key of “Japanese”, “English”, “French”, “Italian”, “German”, “Spanish” is displayed. When any language key is pressed, a list of messages in that language is extracted and displayed on the display unit 4.

  In this embodiment, for the sake of convenience, extraction in units of “screen” is set, and the following description will be made assuming that the “basic setting screen” key is pressed from the screen keys shown in FIG.

  When the “basic setting screen” key is pressed from the screen keys shown in FIG. 4, the messages displayed on the basic setting screen 4b of FIG. / Original ”,“ image quality / density ”,“ application settings ”,... Are displayed as a list as shown in the message list display screen 4d in FIG. When the message cannot be displayed, it is displayed over a plurality of pages, and the next page key or the previous page key can be used to advance the page.

  When the user presses a key on which a message to be changed is displayed, a message detail screen (FIG. 9) 4e described later is displayed.

  Further, in the message list display screen 4d shown in FIG. 8, when the extracted message character string is long and the display space for other character strings is impaired, only a part of the message may be displayed. Good.

  In the message detail screen 4e of FIG. 9, the details of the message are displayed. For example, in the list display of FIG. 8, when “Can copy” is selected as the message to be changed, a confirmation message is displayed, and “Can copy” is rewritten within the range of width “38” and line “1”. Input becomes possible.

  When the user changes the displayed message, when the “change” key 18a is selected, the screen transitions to the message change screen 4f in FIG. If the message is not changed, the “cancel” key 18b is pressed.

  In the message change screen 4f of FIG. 10, the messages up to now are displayed in the old area, and the user changes the message “I can copy” in the new area. On this screen 4f, in addition to the keyboard part KB which is the input part 1, the "cancel" key 19a and the "OK" key 19b are displayed for the change input of the message. Can be done in the same way.

  When the user finishes changing the new area, the user presses the [OK] key 19b. Then, the character string data after the change is reflected on the screen data stored in the data storage unit 3 by the overall control unit 2.

  Thus, in this embodiment, since the character string can be changed on the display screen by the input unit 1 and the display unit 4 of the own device, it is not necessary to use an external device and the system is simplified.

  In this embodiment, messages (character strings) are extracted and displayed in a list for each unit of “screen”, “function”, “application”, and “language”. There is an advantage that the target message can be easily specified.

  Further, even if only a part of the message list display screen 4d shown in FIG. 8 is displayed because the message character string is long, when this message is selected, the screen 4e and FIG. On the screen 4f, the selected message is displayed over the entire length. For this reason, even if it is a long message, change input becomes easy.

  FIG. 11 is a flowchart showing the character string changing process.

  This character string changing process is a process executed after the user finishes inputting a new message and presses the [OK] key 19b on the message changing screen 4f shown in FIG.

  In FIG. 11, it is determined in step S101 whether the new character string of the message is longer than the old character string. If the new character string is not longer than the old character string (NO in step S101), in step S111, Then, the old character string stored in the data storage unit 3 is overwritten and updated with the new character string, and this processing is terminated. When the new character string is longer than the old character string (YES in step S101), the process proceeds to step S102.

  In step S102, it is determined whether or not the spare area has a sufficient size. If the spare area does not have a sufficient size (NO in step S102), an insufficient free area is displayed and updated in step S112. The user is notified of the failure, and the process is terminated. If the size of the spare area is sufficient (YES in step S102), the process proceeds to step S103.

  In step S103, the head pointer of the spare area is assigned to the work 1, and then in step S104, a new character string length is added to the pointer to the spare area in order to secure a new character string area in the spare area. In S105, the new character string length is subtracted from the spare area length.

  As described above, the work 1 indicates a pointer of an area into which the new character string is to be inserted. Therefore, in step S106, the new character string is copied to the work 1.

  Next, in step S107, the pointer to the old character string is copied to the work 2, and in step S108, the pointer to the character string in the edited text part is set to work 1.

  Next, in step S109, a pointer to the unused area is recorded in the area of the old character string pointed to by the work 2, and then in step S110, the work 2 is recorded in the pointer data to the unused area, and this process ends. . As described above, the link to the unused area is formed from the pointer to the unused area.

  This data is used when garbage collection of an existing technology (not shown) is performed.

  By the way, when the character string is changed and “input beyond the display area” is permitted on the display screen in the normal display mode, the portion exceeding the display area is hidden and not displayed on the display screen.

  Therefore, in this embodiment, when the changed character string is stored in the data storage unit 3, data is set so that scroll display of the character string is possible.

  FIG. 12 is a basic setting screen 40b for explaining an example of scroll display.

  At the bottom of the basic setting screen 40b, a "Save in box" key 20a, a "Continuous reading" key 20b, and a "Finish" key 20c are displayed. The "Continuous reading" key 20b displays "Continuous" A character string “reading setting” is set.

  FIG. 6A shows the initial display “continuous reading”. When the right-pointing triangle key on the right side of “continuous reading” is pressed, one character scrolls and “continuous reading” is performed as shown in FIG. Is displayed. When the right triangle key is further pressed, “reading setting” is displayed as shown in FIG. Thus, each time the triangle key is pressed, the character string to be displayed is scrolled one character at a time and displayed within the frame.

  FIG. 13 is a screen 40g showing another display example of scrolling.

  As in FIG. 12, a character string “continuous reading setting” is set in a four-character display frame in which “continuous reading” is displayed.

  In this example, the display is switched at regular time intervals, so that the display is automatically scrolled one character at a time from (A) to (I) in FIG. Return to (A).

  Thus, by providing the scroll display function, it is possible to change even a character string that exceeds the display area, and it is possible to easily grasp the entire character string by scroll display. Further, since it is not necessary to reduce the font size, there is no problem that characters in the character string are crushed and difficult to see.
