and 12 are laminated with two transparent conductive films 13 and 14 such as ITO, and the transparent conductive films 13 and 14 are opposed to each other and bonded to each other with an insulating spacer 15 using double-sided tape 16 or the like. Then, by pressing the touch surface 17 of the insulating substrate 11 with a fingertip, the spacer 15
The transparent conductive films in the divided regions are brought into contact with each other and electrically conductive.

そのとぎれを連続したものと補正しているが、逆に点線
を連続線として表示してしまう欠点があった。(Problem to be Solved by the Invention) However, when used in a handwriting input device etc., the input is interrupted at the spacer and input errors occur, so normally a circuit is used to correct the interruption as a continuous one. On the contrary, there was a drawback that the dotted line was displayed as a continuous line.
本発明の目的は、以上の欠点を改良し、入力ミスを防正
しうる透明タッチパネルを提供するものである。An object of the present invention is to provide a transparent touch panel that can improve the above-mentioned drawbacks and prevent input errors.

。(Means for Solving Problems) In order to achieve the above object, the present invention provides a transparent touch panel in which insulating substrates with a transparent conductive film laminated on the surface are bonded together, in which liquid or gas is sealed between the insulating substrates. The present invention provides a transparent touch panel characterized by:

げるなめに、透明導電膜を導通できる。(Function) The transparent conductive film is normally insulated because a liquid or gas is interposed therebetween instead of a spacer, and becomes conductive only when the touch surface is pressed to input a signal. Furthermore, no matter where you press the touch surface, the transparent conductive film can be electrically conductive without allowing liquid or gas to escape.
(実施例) 以下、本発明を実施例に基づいて説明する。(Example) Hereinafter, the present invention will be explained based on examples.

導電膜3及び4か互いに接触して導通する。According to the above embodiment, the transparent conductive films 3 and 4 are insulated by the liquid or gas 6 when the touch surface 7 of the insulating substrate 1 is not pressed. As shown in the second figure, when any part of the touch surface 7 is pressed, the transparent conductive films 3 and 4 come into contact with each other at the pressed part and become electrically conductive.

る。<Effects of the Invention> As described above, according to the present invention, since the transparent conductive films are insulated by liquid or gas instead of a spacer, the transparent conductive films are electrically conductive no matter where on the touch surface is pressed. A transparent touch panel that can input output signals and prevent input errors is obtained.
