Thus, the insensitive state for prohibiting the process of detecting the position of the touch operation is controlled.

  FIG. 4 is a plan view schematically showing the touch panel display device 1 used in the information processing apparatus 10 of FIG. 3 as viewed from above.

  In FIG. 4, the information processing apparatus 10 according to the first embodiment includes a touch panel display device 1. Here, a state is shown in which two users 13b and 13c are inputting various information using the virtual keyboards 14b and 14c displayed on the display screen of the touch panel display device 1, respectively. Although not shown here for simplification, the other two users also input information from the respective left and upper sides using a virtual keyboard (not shown). As described above, the information processing apparatus 10 according to the first embodiment is configured to display the virtual keyboards 14 b and 14 c and perform information processing using the touch panel display apparatus 1.

  The cleaning area selection switches 31 to 34 are switches for setting the cleaning mode or canceling the cleaning mode in units of touch panel areas (display area units) of each user constituting the display screen. When each user sets the cleaning mode using the cleaning area selection switches 31 to 34, the key inputs of the virtual keyboards 14a to 14d (the virtual keyboards 14a and 14d are not shown) from the touch panel body 21b of the touch panel display device 1 are invalid. Therefore, it is possible to easily perform a cleaning operation of wiping the display screen while suppressing an unintended input operation.

  As described above, the cleaning area selection switches 31 to 34 function as display area selection switches 12a to 12d as button switches. However, the present invention is not limited to this, and the cleaning area selection switches 31 to 34 perform cleaning on the virtual keyboard. It may be a display key of the area selection switch 211B. Both the button switches of the cleaning area selection switches 31 to 34 and the display key of the cleaning area selection switch 211B may be provided, or one of them may be provided.

FIG. 5A is a plan view schematically showing an example of a state in which the touch panel display device 1 for explaining a cleaning target area corresponding to each user is viewed from above.

  In the touch panel display device 1A of FIG. 5A, the areas 21a to 21d to be cleaned are divided into four areas corresponding to the seats of the four users 13a to 13d. For example, when the cleaning area selection switch 32 of the cleaning area selection switches 31 to 34 (the cleaning area selection switches 31 and 34 are not shown here) is pushed once, input command information from the cleaning area selection switch 32, for example, is input. Is transmitted to the cleaning state determination unit 4.

  The cleaning state determination unit 4 includes a memory (not shown) so as to correspond to the position of the cleaning target area 21b.

  Here, this memory records flag information composed of two numerical values. In this embodiment, as shown below, the lower 1 digit indicates the setting and release of the cleaning mode, and the upper 1 The setting indicates that the digit indicates the display of the area to be cleaned, and indicates cancellation.

   When the cleaning area selection switch 32 is pressed and position information is input, it is stored in a memory (not shown) corresponding to the position information, and a flag is set to “01” in the memory (not shown). The flag information is transmitted to the touch panel control circuit 22 in the touch panel display unit 2 via the bus 5, and the touch panel control circuit 22 controls the touch panel body 21B so as to invalidate the touch input in the cleaning target area 21b. At the same time, a flag of a memory (not shown) in the cleaning state determination unit 4 is set to “11”.

  Next, in response to this, the cleaning target area 21b is displayed in a predetermined color, and the setting of the cleaning mode is completed. That is, flag information “11” of a memory (not shown) in the cleaning state determination unit 4 is transmitted to the display unit main body control unit 23 via the bus 5. Upon receiving the flag information “11” from the memory (not shown), the display unit main body control unit 23 performs, for example, halftone color display (for example, soft yellow display in the cleaning target area 21b) on the entire cleaning target area 21b. This can clearly indicate that the cleaning mode is set.

  As described above, the display unit main body control unit 23 displays the cleaning target area by changing the display color for each cleaning mode setting area on the display screen.

  Since the cleaning mode setting clarification method is halftone color display, the user 13b can recognize the information displayed immediately before. The user 13b can perform a necessary cleaning operation for the cleaning target area 21b.

  Thereafter, when the cleaning mode of the cleaning target area 21b is canceled, the cleaning area selection switch 32 is pushed once again. The input command information input by one push to the cleaning area selection switch 32 is transmitted to the cleaning state determination unit 4, and the flag information “11” in the memory (not shown) of the cleaning state determination unit 4 becomes “10”.

  This flag information “10” is transmitted to the touch panel control circuit 22 in the touch panel display unit 2 via the bus 5, and the cleaning mode of the cleaning target area 21b is canceled. As a result, the touch panel display unit 2 returns to the normal operation and receives a touch input.

  Further, in response to this, the upper side of the flag information is also reset, and the flag information in the memory (not shown) becomes “00”. The flag information “00” in this memory (not shown) is then transmitted to the display unit main body control unit 23 via the bus 5.

  Next, the display main body control circuit unit 23 cancels the halftone yellow color display of the entire cleaning target area 21b based on the flag information “00” of the memory (not shown), and the display unit main body 21A Return to the display state. The user 13b confirms that the display state is normal, and the cleaning mode of the cleaning target area 21b is released, and the user 13b can know that the state has changed to a state in which key input from the virtual keyboard is accepted.

  Similarly, when each of the users 13a, 13c, and 13d pushes the cleaning area selection switches 31, 33, and 34 other than the cleaning area selection switch 32, the corresponding flag memory (not shown) has a cleaning. “01” is set in each flag of a memory (not shown) corresponding to each of the target areas 21a, 21c, and 21d. Thereby, the cleaning target areas 21a, 21c, and 21d are set to the cleaning mode from the cleaning state determination unit 4 via the touch panel control circuit 22 and the display main body control circuit unit 23.

  Thereafter, after the cleaning operation of the respective cleaning target areas 21a, 21c, and 21d is finished, the cleaning mode of the cleaning target areas 21a, 21c, and 21d is canceled when the cleaning area selection switches 31, 33, and 34 are pushed again. .

  The display area coordinate data of the cleaning target areas 21a to 21d is stored in the cleaning state determination unit 4 in advance. For this reason, when receiving the flag information from the flag memory (not shown), the touch panel control circuit 22 and the display unit control unit 23 identify the cleaning area selection switch corresponding to the flag information, thereby cleaning the area 21a. Each of the display area coordinate data of ˜21d is read from the cleaning state determination unit 4, and the invalidation area of the touch panel input and the halftone color display area can be determined based on the read coordinate data. Since the entire display screen is assigned to any one of the users 13a to 13d, an area that can be set to the cleaning mode based on the determination of each user 13a to 13d can be widened.

  When the cleaning mode is set, touch key input on the virtual keyboard is invalidated.

  At this time, as shown in FIG. 5A, in the configuration in which the drive circuit of the touch panel unit main body 21B is provided in the horizontal axis direction and the read signal corresponding to the drive signal is output in the vertical axis direction, the cleaning target area 21a is in the cleaning mode. When this is set, the touch area detection drive of the cleaning target area 21a is not necessary. That is, when the cleaning target area 21a is set, a flag memory (not shown) corresponding to the cleaning target area 21a provided in the cleaning state determination unit 4 becomes “11”, and in this state, the cleaning target area 21a is touched. Area detection driving is not necessary. In this state, the cleaning state determination unit 4 sends a power save mode signal to the touch panel control circuit 22. The touch panel control circuit 22 that has received the power save mode signal can reduce power consumption in the drive unit of the touch panel unit body 21B by controlling the drive signal of the cleaning target area 21a of the touch panel unit body 21B to stop processing. .

  Next, the case where a common cleaning target area is provided at the center of the touch panel body 21B will be described with reference to FIG. 5B.

  FIG. 5B is a plan view schematically illustrating another example of a state in which the touch panel display device 1 for explaining a cleaning target area corresponding to each user is viewed from above.

  In the touch panel display device 1B of FIG. 5B, the areas 21a, 21b ′, 21c, 21d ′, and 21e to be cleaned are common cleaning objects in the center in four areas corresponding to the seats of the four users 13a to 13d. The area is divided into five areas including the area 22e. The procedure for setting / releasing the cleaning mode of the areas to be cleaned 21a, 21b ', 21c, 21d' and 21e is the same as in FIG. 5A and is as follows.

  First, for example, when the cleaning area selection switch 32 is pushed once, the input command information of the cleaning area selection switch 12b is transmitted to the cleaning state determination unit 4.

  The cleaning state determination unit 4 includes a memory (not shown) corresponding to the cleaning target area 21b.

  Here, this memory records flag information composed of three numerical values. In the present embodiment, as shown below, the lowest one digit sets and cancels the cleaning mode of the area to be cleaned. The uppermost 1 digit indicates the setting and release for indicating the display of the cleaning target area, and the middle digit indicates a cleaning request for the common cleaning target area 22e.

   When the cleaning area selection switch 32 is input, “001” is set in a flag of a memory (not shown). The flag information “001” is transmitted to the touch panel control circuit 22 in the touch panel display unit 2 via the bus 5, and the touch panel control circuit 22 makes the touch input to the cleaning target area 21b ′ invalid. To control.

  At the same time, “101” is set in the flag of the memory (not shown). Thus, the cleaning target area 21b 'is displayed in a predetermined color (yellow), and the cleaning mode is completed. That is, the flag information “101” in the memory (not shown) is transmitted to the display unit main body control unit 23 via the bus 5. Upon receiving the flag information “101”, the display unit main body control unit 23 displays the entire area to be cleaned 21b ′ in a yellow halftone color and clearly indicates to the user 13b that the cleaning mode is set.

  In addition, since the cleaning mode setting specifying method is a halftone color display, the information displayed immediately before can also be recognized. When the user 13b finishes the necessary wiping of the cleaning target area 21b 'and cancels the cleaning mode of the cleaning target area 21b', the user 13b pushes the cleaning area selection switch 32 one time. Information that is input to the cleaning area selection switch 32 by one push is transmitted to the cleaning state determination unit 4, and flag information “101” in a memory (not shown) in the cleaning state determination unit 4 is reset only in the lower bits. “Become. When the flag information “100” is transmitted to the touch panel control circuit 22 via the bus 5, the cleaning mode of the cleaning target area 21 b ′ is canceled, and the state returns to the normal operation and the touch key input of the virtual keyboard is accepted. .

  Next, in response to this, the upper bits of the flag information are also reset, and the flag of the memory (not shown) returns to “000”. The flag information of the memory (not shown) is then transmitted to the display unit main body control unit 23 via the bus 5.

  Further, based on the flag information “000”, the display unit main body control unit 23 releases the halftone yellow color display of the entire cleaning target area 21b ′, and the display unit main body 21A enters the normal display state. The user 13b can confirm that the normal display state has been achieved and know that the cleaning mode of the cleaning target area 21b 'has been canceled and the state has changed to a state in which key input from the virtual keyboard is accepted.

  Similarly, when each of the cleaning area selection switches 31, 33, and 34 other than the cleaning area selection switch 32 is pushed, “001” is set in the flag memory (not shown) corresponding to each of the cleaning area selection switches 31, 33, and 34. When the areas 21a, 21c and 21d ′ are set to the cleaning mode and the cleaning operation of the respective cleaning target areas 21a, 21c and 21d ′ is finished, and the cleaning area selection switches 31, 33 and 34 are pushed, the cleaning target areas The cleaning mode of 21a, 21c and 21d ′ is canceled.

  Since the display area coordinate data of the cleaning target areas 21a, 21b ′, 21c, and 21d ′ is stored in the cleaning state determination unit 4 in advance, the touch panel control circuit 22 and the display unit main body control unit 23 include a flag memory (FIG. (Not shown) flag information is received, the cleaning area selection switches 31 to 34 corresponding to the memory (not shown) in which the flag information is stored are identified, whereby the cleaning target areas 21a, 21b ′, 21c and 21d ′ are identified. Each of the display area coordinate data is read from the cleaning state determination unit 4, and based on the read coordinate data, it becomes possible to determine the invalidation area of the touch panel input and the halftone color display area.

  Next, handling of the common cleaning target area 21e in the center will be described.

  The common cleaning target area 21e cannot be set to the cleaning mode by each of the users 13a to 13d '. The cleaning mode can only be set by operating all the cleaning area selection switches 31 to 34 so that all the users 13a to 13d 'set the cleaning mode. That is, the common cleaning target area 21e is an area common to all users 13a to 13d.

  For example, when the user 13b continuously presses the cleaning area selection switch 32 twice or more (hereinafter referred to as double push), an information input command of the cleaning area selection switch 32 to which the double push has been input is transmitted to the cleaning state determination unit 4. The cleaning state determination unit 4 includes a memory (not shown) corresponding to the cleaning target area 21b ′. When the cleaning area selection switch 32 is double-pushed, the memory (not shown) of the cleaning target area 21b ′ of the user 13b is displayed. No.) is set to “010”.
