Indication inputting device

Abstract

The present invention provides a pointing input device, which sequentially outputs pointing position data indicating a pointing input position and push detection data from a push by the same pen or finger used for a pointing input. The pointing input device includes a display panel (4) for displaying any pointing input information (11), and an optical touch panel (9). The optical touch panel (9) detects the pointing input in an input operation area (9A), through which a display area is visible, and outputs the pointing position data. Piezoelectric substrates (6A, 6B) are attached to a transparent protective plate (5) protecting the top surface of the display panel (4). When an operator pushes the transparent protective plate disposed at the lower part of the optical touch panel while carrying out the pointing input, the piezoelectric substrates (6A, 6B) output electric signals by which the push is judged. Then, the push detection data is outputted with the pointing position data.

Description

Technical field [0001] The present invention relates to an instruction input device that can execute prescribed instructions while watching instruction input information displayed on a display panel. More specifically, it relates to an instruction input device that uses an optical touch screen to detect an instruction input position. By pressing the display position of the instruction input information, a prescribed command corresponding to the instruction input information can be executed. Background technique [0002] Conventionally, there is known an instruction input device in which an optical touch screen is laminated on a display panel composed of a CRT or a liquid crystal display device (for example, refer to Japanese Patent Document 1). The display panel displays information for various instruction input, and the operator can perform instruction input at the corresponding position while observing the display content in the input operation area of ​​the optical touch scree...

AI Technical Summary

Problems solved by technology

[0016] In order to output the pressing detection data, it is possible to install or add other pressing detection switching mechanisms, etc., but the overall size of the device will be increased, and the pressing detection switching mechanism cannot be operated with the same fingers or pens used for instruction input, so there may be cases where both hands are not used. the problem of inoperability

[0017] In addition, if the light beam is momentarily blocked, it is regarded as an instruction input, so for example, only water droplets or insects pass through the input operation area 107A, and there will be a problem of malfunction.
