  Following the processing of S201, it is determined whether the user name of the variable IUN has been registered as user information stored in the user information storage area 351 (S202). The user information in which the user name of the variable IUN is registered is set in the variable SUI (S210), and the process is terminated.

  If it is determined in S202 that the user name of the variable IUN is an unregistered user name, first, unused user information is set in the variable SUI (S220).

  Following the processing of S220, the operation screen initial registration unit 121 is executed, and the operation screen is automatically selected and set to the variable ASP (S221).

  Following the processing of S221, the color information initial registration unit 122 is executed to automatically select the color information and set it in the variable ASC (S222).

  Finally, the user information set in the variable SUI is initially registered (S223), and the process is terminated.

  The more detailed processing content of S223 is that the value set in the variable IUN in S201 is initially registered as the user name UN of the user information. The group information G1 stored in the group information storage area 352 is initially registered in the user information selection group SG. As the selection color SC of the user information, the value set in the variable ASC in S222 is initially registered. On the user information selection screen SP, the value set in the variable ASP in S221 is initially registered.

  FIG. 12 shows the processing contents of the operation screen initial registration unit 121 read out and executed by the processing means 10, and will be described below.

  First, the random number generator 60 is initialized so as to generate n random numbers corresponding to the number of operation screens stored in the main operation screen storage area 323 (S250), and the generated random number is set to a variable R (S251).

  Then, information specifying the operation screen stored in the variable R-th main operation screen storage area 323 is set in the variable ASP (S252), and the process is terminated.

  FIG. 13 shows the processing contents of the color information initial registration unit 122 read out and executed by the processing means 10, and will be described below.

  First, the number of color information C1 to Cy stored in the color information storage area 353 and having the flag FG of 0 is calculated and set to the variable cnt (S260).

  Following the processing of S260, it is determined whether or not the variable cnt has a zero value (S261). That is, it is determined whether or not all the color information C1 to Cy has been automatically selected.

  If it is determined in S261 that all the color information has been automatically selected, the flags FG of the color information C1 to Cy are initialized to 0 value in order to initialize the state (S262), and the variable cnt The value is set to the number y of color information stored in the color information storage area 353 (S263).

  If it is determined in S261 that all color information has not been automatically selected, and subsequent to the processing in S263, the random number generator 60 is initialized so that random numbers according to the variable cnt are generated (S264). The random number is set to the variable R (S265).

  Subsequent to the processing of S265, the variable R-th color information among the color information C1 to Cy in which the flag FG is 0 is searched, and information for specifying the searched color information is set in the variable ASP. (S266).

  Finally, in order to set the flag FG of the color information of the variable ASP to the state of being automatically selected, one value is set (S267), and the process ends.

  As described above, in the display operation device 1 of the present invention, when an instruction for requesting registration of a new user of the display operation device is detected, the arrangement of the display objects constituting the operation screen and the operation screen are displayed. An arbitrary operation screen is selected from among a plurality of operation screens having different color information, and is registered as a new user operation screen. That is, different operation screens are arbitrarily selected and initially registered for users who do not set the color scheme or button layout of the operation screens. This makes it difficult for a third party to estimate whether or not the user has set the operation screen, thereby preventing the user's privacy from being unnecessarily leaked.

  First, timing is started (S400), and it is determined whether a user operation on the input unit 25 is detected (S401). In this determination, if no user operation is detected, it is determined whether or not a certain time has elapsed from the start of time counting in S400 (S402). ”Is output to the main control unit 11 (S403), and the process is terminated.

  If it is determined in S402 that the predetermined time has not elapsed, the process proceeds to S401 in which it is determined whether a user operation has been detected.

  If a user operation is detected in the determination of S401, it is determined whether the user operation is an operation of the operation button 252 (S410). If it is determined that the operation button 252 is operated, an operation code for the operation button 252 is output to the main control unit 11 (S411), and the process is terminated.

  If it is determined in S410 that the operation button 252 is not operated, whether or not the operation is an operation of a display object constituting the operation screen displayed on the display unit 21 is determined. This is determined with reference to the operation position OPS of the display object (S420). As a result of the determination, when it is determined that the operation is not a display object, it is determined that the user's operation has not been performed, and the process proceeds to S401 for determining whether the user's operation has been detected.

  If it is determined in S420 that the operation is a display object, the operation code OCD of the display object is output to the main control unit 11 (S421), and the process ends.

  FIG. 17 shows the processing contents of the operation screen changing unit 15 read and executed by the processing means 10 and will be described below.

  First, a list of reduced screens of n operation screens of the operation screens P1 to Pn stored in the main operation screen storage area 323 is displayed (S600), and the user selects an operation screen to be used (S601).

  Following the above processing, information for specifying the selected operation screen is set in the selection screen SP for user information set in the variable SUI (S602), and the processing is terminated.

  FIG. 18 shows the processing contents of the color information changing unit 16 read out and executed by the processing means 10, and will be described below.

  First, using each of the color information C1 to Cy stored in the color information storage area 353, a confirmation sample screen for the number y of stored color information is displayed (S700), and the color information to be used is displayed. Let the user select (S701).

  Subsequent to the above process, the information for specifying the selected color information is set to the selected color SC of the user information set in the variable SUI (S702), and the process ends.

  Thus, in the display operation device 1 of the present invention, the operation screen can be changed from the plurality of operation screens to the operation screen designated by the user. From this, it is possible to change to an operation screen that is easy for a visually handicapped person such as color blind to visually recognize, and to change the arrangement of frequently used buttons so that the user can easily operate.

  FIG. 19 shows the processing contents of the group changing unit 17 read and executed by the processing means 10, and will be described below.

  First, in order to confirm the user of the currently selected group name, the group name GN of the group information specified by the selected group SG of user information set in the variable SUI is displayed (S800), and the group to be changed Is designated by the user (S801).

  Following the above process, information for specifying the designated group is set in the selected group SG of the user information set in the variable SUI (S802), and the process ends.

  As described above, in the display operation device 1 of the present invention, different operation screens are arbitrarily selected and initially registered even for users who do not set the color scheme or button layout of the operation screen. This makes it difficult for a third party to estimate whether or not the user has set the operation screen, thereby preventing the user's privacy from being unnecessarily leaked.

  Here, part or all of the control programs according to FIGS. 10 to 14 and FIGS. 16 to 19 read out to the display operation device according to the present embodiment are the display operation device according to the present embodiment. It can also be recorded in advance on a recording medium attached to and provided as a program product. As such a recording medium, there is a recording medium readable by each display operation device such as a CD (Compact Disc) or a memory card. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the display operation device according to the present embodiment. Further, it can be provided by downloading through various networks including the Internet.

  In general, various program modules are prepared as a part of the operating system, and each control program calls the modules when necessary to advance the process. In such a case, each control program itself for realizing the display operation device according to the present embodiment does not include these modules, and is realized in cooperation with the operating system. However, as long as a general operating system is used, it is not necessary to distribute each control program including these modules, and each control program itself not including these modules and a recording medium on which each control program is recorded. (And data signals in the case where each of these control programs circulates on the network) can be considered to constitute the embodiment.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
