Abstract

PROBLEM TO BE SOLVED: To prevent erroneous input of information when a cleaning work of a touch panel is performed without requiring any special instruction. SOLUTION: An input part 101 detects contact with the touch panel and outputs presence/absence of the contact and coordinate information of a contact surface when the contact exists to an input detecting part 102. The input detecting part 102 judges whether or not transfer exists in a depression point of the touch panel from information about change of coordinates of the depression point. In addition, when no transfer exists in the depression point, the input detecting part 102 judges that input of the information exists from the touch panel and outputs depression of a picture and the depressed coordinates to a control part 103. The control part 103 judges that the touch panel is cleaned and performs an operation in a cleaning mode when the transfer exists in the depression point. And when no transfer exists in the depression point, the input is judged to be performed from the touch panel and the operation is performed in a normal mode.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel control device, a touch panel control method, and a touch panel control program, and more particularly to a touch panel control device, a touch panel control method, and a touch panel control for performing screen display and information input on one panel. About the program.

[0002]

2. Description of the Related Art In general, in a system in which operation is facilitated, a touch panel for inputting an instruction or information by touching a screen displayed on a screen display unit is widely used.

In a touch panel of this type, for example, an optical system that generates a position coordinate signal of a finger by closing a part of a matrix formed by an optical axis of infrared light with a finger, or a transparent electrode or a fine conductive line is used. A conductive sheet system or the like that generates a position coordinate signal of a finger by pressing a formed matrix switch with the finger is known. Using these methods, the touch panel detects a touch operation on the screen and outputs a position coordinate signal of the touched screen.

[0004] In such a touch panel, a portion that is frequently touched on the screen is stained. Therefore, it is necessary to periodically clean the screen. As a cleaning method, stop the system in advance, wipe the screen with a cloth to clean it, restart the system after the screen cleaning is completed, or paste a transparent protective sheet on the screen in advance, and In some cases, the protection sheet on the screen is peeled off to complete the cleaning, and the system is restarted as described above. On the other hand, when cleaning the screen while the system is operating, it is necessary to carefully clean the screen so as to prevent malfunction due to the reaction of the touch panel.

[0005] As a touch panel cleaning method for preventing malfunction due to screen cleaning, there is a method described in Japanese Patent Application Laid-Open No. Hei 8-22375. In this cleaning method, when the screen is cleaned, a malfunction due to the cleaning of the screen is prevented by setting the cleaning state unresponsive to the position coordinate signal received from the touch panel for a predetermined time.

[0006]

However, the conventional apparatus has a problem that information is erroneously input when the touch panel is cleaned. Further, when the system is stopped, there is a problem that necessary information such as emergency information is overlooked. Further, when the touch panel is cleaned, a method of switching to a cleaning state that is insensitive to input from the touch panel to prevent erroneous input requires an instruction to switch to the cleaning state. Further, there is a problem that the cleaning time cannot be arbitrarily set in the method for setting the cleaning state for a predetermined time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and does not require special instructions, and can prevent erroneous input of information when performing operations such as cleaning the touch panel. It is an object to provide a control method and a touch panel control program.

Are adopted.

In the touch panel control device according to the present invention, the judging means stops the pressing after the pressing point moves while the touch panel screen is being pressed based on the detected pressing presence / absence information and the pressing point information. The switching means determines whether or not the operation has been performed, and switches the operation of the touch panel to the cleaning mode when the pressing point is stopped after the pressing point moves while the screen of the touch panel is pressed.

By making the input information valid, it is possible to return the touch panel control device to a normal input state without performing a special operation after cleaning is completed.

[0020] The touch panel control device of the present invention further comprises a timer for measuring a time during which the screen is not pressed in the cleaning mode based on the detected press presence / absence information. When the time during which the screen is not pressed is equal to or longer than a predetermined time, the operation of the touch panel is switched from the cleaning mode to the normal mode.

According to this configuration, in the input operation of the touch panel, an operation intended for inputting information and an operation intended for cleaning are determined based on the movement of the pressed point of the touch panel.

The input unit 101 includes a touch panel or the like, detects contact with the touch panel, and outputs to the input detection unit 102 the presence or absence of the contact and the coordinate information of the contact surface where the contact has occurred.

Hereinafter, the operation of touching the contact surface of the touch panel is referred to as “pressing”, and the point of contact of the contact surface is referred to as “pressing point”.

More specifically, when the screen is pressed, that is, when the touch panel is touched, the input unit 101 outputs to the input detection unit 102 that the screen has been pressed and the pressed coordinates.

When the touched point is moved, for example, when the touching point is moved while touching the touch panel due to cleaning of a panel or the like, the input unit 101 detects a change in the coordinates of the pressed point by the input detecting unit 102. Output to When the pressing of the screen is stopped, that is, when the touch panel is released, the input unit 101 outputs to the input detecting unit 102 that the pressing of the screen is stopped.

The input detection unit 102 determines whether or not the touched point of the touch panel has moved based on the information on the change in the coordinates of the touched point output from the input unit 101. Has been cleaned,
The fact that the screen is wiped is output to the control unit 103.

If there is no movement at the pressed point, the input detection unit 102 determines that information has been input from the touch panel, and determines from the information output from the input unit 101 that the screen has been pressed and the pressed coordinates. Is output to the control unit 103.

If there is a movement at the pressed point, the control unit 103 determines that the touch panel is being cleaned, and operates in the cleaning mode. If there is no movement at the pressed point, it is determined that there is an input from the touch panel, and the operation is performed in the normal mode.

Here, the cleaning mode is a mode in which the input from the touch panel is invalidated and the contact of the touch panel during cleaning of the touch panel is prevented from being input as erroneous information. The normal mode is a mode in which information input from the touch operation of the touch panel is validated and output to the outside.

The display unit 104 displays information according to an instruction from the control unit 103. For example, when in the cleaning mode,
Information indicating the cleaning mode can be displayed on the screen. In addition, power consumption can be reduced without displaying a screen during operation in the cleaning mode.
