  The display means 2 is arranged at a substantially central portion of the front panel, and displays an image of a screen switch for operation and setting of the information terminal device 1 and a state based on a command from the arithmetic processing unit 4. The second operation unit 3 is a transparent touch panel sheet disposed on the display unit 2, and is a contact such as an electrostatic switch disposed corresponding to the switch image for operation and setting displayed on the display unit 2. The two-dimensional position information, which is configured by an expression switch and the user presses the second operation unit 3, is input to the arithmetic processing unit 4 as the input signal 30, and the arithmetic processing unit 4 displays the position displayed on the display unit 2. The content of the operation performed by the user is determined from the information and the position information of the input signal from the second operation unit 3, and processing based on this is performed.

The first operation unit is composed of three switches 5a, 5b and 5c, and the display means 2 on the front panel.
Is a switch for selecting and instructing an operation different from that of the second operation unit 3 constituted by the touch panel of the display means 2, particularly for an instruction of an operation frequently used by a user every day. Operation switch. These input signals are input to the arithmetic processing unit 4 as input signals 50a, 50b, and 50c, respectively. When the user operates the first operation units 5a, 5b, and 5c, the arithmetic processing unit 4 determines the content of the operation performed by the user from the input signals 50a, 50b, and 50c from the first operation unit. Based on the processing.

  In the embodiment of the present invention, the first operation unit is composed of three switches as described above, but this is an example, and the number of operation switches is not limited.

  When an electrostatic switch or the like is employed as the first operation unit 5a, 5b, or 5c, it reacts even by lightly touching like the touch panel, so when wiping off dirt adhered to the operation switch (hereinafter referred to as “cleaning mode”). However, it is necessary to take a measure that does not respond even if it touches the operation switch like the touch panel.

  In the embodiment of the present invention, as shown in FIG. 2, the second operation unit 3 configured with a touch panel and the first operation units 5a, 5b, and 5c as operation switches arranged on the front panel are arranged on the same plane. The recovery switch 6 is arranged at a position where the second operation unit 3 and the first operation units 5a, 5b, and 5c are not in the same plane. This makes it easy to clean the entire surface of the front panel on which the second operation unit and the first operation unit are arranged, and at the same time prevents accidental pressing of the recovery switch during cleaning.

  In addition, as shown in FIG. 3, when the 2nd operation part 3 and 1st operation part 5a, 5b, 5c are not on the same plane and there are some level | step differences, these are on the same plane However, the effect of being able to wipe off both stains at the same time is almost the same.

  Here, when the cleaning mode is selected, the operation signal is input to the arithmetic processing unit 4 by contacting the cleaning mode selection means 41 of the second operation unit 3 configured by the touch panel shown in FIG. Can be set to a mode in which reception of an input signal to the arithmetic processing unit 4 is prohibited only during a preset initial setting time, that is, the cleaning mode.

  When the cleaning mode execution time is to be changed, when the menu screen setting means 40 is touched, the screen is switched to a screen displaying a plurality of menus. When the cleaning mode execution time setting mode is selected from this menu, FIG. As shown, the calculation processing unit 4 displays the image information 30a, 30b, 30c of the screen switch for setting the execution time of the cleaning mode on the display means 2, and the user operates the second operation unit 3 arranged thereon. When pressed, the input signal 30 from the second operation unit 3 is interpreted, and the arithmetic processing unit 4 stores the cleaning mode execution time in accordance with the setting of the user in the storage unit 8. When it is selected, this time is set as an execution time, which acts as a mode for prohibiting reception of an input signal to the arithmetic processing unit 4.

  In the present embodiment, the cleaning mode selection means 41 is configured using the second operation unit 3 configured by a touch panel, but is not limited thereto, and the first operation units 5a, 5b, and 5c are used. By adopting a configuration that does not allow easy mode switching such as multiple operation or long press operation, the same setting can be performed.

FIG. 5 shows a processing sequence performed by the arithmetic processing unit 4 of the information terminal device 1 in accordance with input information from the second operation unit 3. In step S <b> 1, it is determined whether or not there is an input signal of the cleaning mode selection means 41 from the second operation unit 3. If it is determined that there is no screen key input, the process returns to step S1 again. If it is determined that there is a screen key input, the process proceeds to the next step S2.

  In step S2, the information of the input signal 30 from the second operation unit 3 is determined, and when the information of the input signal determines that the cleaning mode selection means 41 has been input, the process proceeds to step S3 and the cleaning mode is entered. If it is determined that the request is not a switching request, the process proceeds to step S9.

  In step S9, according to the information of the input signal, a process corresponding to the information is executed, and the process returns to step S1 again. In step S3, the timer set value stored in the storage means 8 is read. At this time, when the cleaning mode execution time setting mode is selected in advance by the menu screen setting means 40 and an arbitrary execution time is set, the time is read. When the execution time is not set, a preset initial time is set. Read the set time and use it as the timer set value. In the next step S4, the timer means 7 is set and started with the read set value, and in the next step S5, a mode for prohibiting the reception of the input signal to the arithmetic processing unit 4 is set, arranged on the front panel and operated. A process of invalidating the input signals 50a, 50b, 50c, and 30 from the first operation unit 5a, 5b, 5c acting as a switch and the second operation unit 3 configured with a touch panel is performed, and in the next step S6, display is performed. A message indicating that the operations of the first operation units 5a, 5b, 5c and the second operation unit 3 are invalid is displayed on the means 2.

  Here, FIGS. 6a and 6b show an example of the contents displayed on the display means 2 in step S6. FIG. 6a displays that the cleaning mode is being performed, the total time of the cleaning mode, and the elapsed time since the transition to the cleaning mode as numerical values and image information. Further, FIG. 6B displays the fact that the cleaning mode is being performed, the total time of the cleaning mode, and the remaining time until the completion of the cleaning mode as numerical values and image information.

  Steps S5 and S6 after the start of the timer means 7 in step S4 determine whether there is a timer completion input in step S7 and whether there is an input signal from the recovery switch 6 in step S8. Process.

  If the arithmetic processing unit 4 determines in step S7 that there is a completion input from the timer unit 7, the operation processing unit 4 proceeds to step S10, and if it determines that there is no input signal from the timer unit 7, the operation processing unit 4 proceeds to step S8. To do. In step S8, when it is determined that there is an input signal from the recovery switch 6, the process proceeds to step S10. When it is determined that there is no input signal from the recovery switch 6, the process returns to step S7 again. Here, the recovery switch 6 is a switch for returning to the normal mode in preference to the cleaning mode selection means 41. The recovery switch 6 can accept even when the cleaning mode is selected and the switch is not in the input acceptance state. The cleaning mode can be canceled before the timer set time elapses by operating the switch 6.

  In step S10, the process of invalidating the input signals 50a, 50b, 50c, and 30 from the first operation units 5a, 5b, and 5c and the second operation unit 3 performed in step S5 is canceled, and in step S11, step 6 is performed. In step S12, the first operation unit 5a, 5b, 5c and the second operation unit 3 displayed on the display unit 2 are erased. In step S12, the timer unit 7 is initialized.

  By the processing sequence as described above, the information terminal device 1 is connected to the second operation unit 3 for the timer time stored in the storage unit 8 when the user selects the cleaning mode selection unit 41 of the second operation unit 3. It changes to the cleaning mode which invalidates the input signal from 1st operation part 5a, 5b, 5c so that a user can wipe off the 2nd operation part 3 and 1st operation part 5a, 5b, 5c in the meantime. At the same time, as shown in FIG. 6a or 6b, the display means 2 displays that it is in the cleaning mode and cannot be used normally.

  If it is desired to change the cleaning mode setting time, the cleaning mode time can be set from the menu screen setting means 40 of the second operation unit 3 and the timer time setting to the storage means can be changed. At this time, not only the image information of the screen switch for setting the execution time of the cleaning mode shown in FIG. 4 but also the user may freely input the set time.

  After the transition to the cleaning mode, it is possible to recover from the cleaning mode to the normal mode by elapse of the timer time stored in the storage means 8 or by pressing the recovery switch 6.

  As shown in FIG. 7, the communication interface 9 connected to the arithmetic processing unit 4 in FIG. 1 is connected to an external control device 20 via a communication line 21. The arithmetic processing unit 4 passes through the communication line 21 via the communication interface 9 based on the information that the user operates the second operation unit 3 and the first operation units 5a, 5b, and 5c via the communication interface 9. Thus, the present invention can be applied to an information terminal device as a remote controller for operating the external control device 20 remotely.
