Gas Cell for Electrostatic Induction Type Touch Input Device
First Claim
1. A gas cell for a touch input device comprising:
- a parallel plate member including two flat plates disposed in parallel and facing each other and having a plurality of electrodes;
a sealing member for sealing a peripheral portion of said parallel plate member in such a manner that gas is accommodated in a gap between said two flat plates in a state that said two flat plates can conduct relative displacement along opposing directions; and
a frame for holding the peripheral portion of said parallel plate member in such a manner that said two flat plates can conduct said relative displacement along opposing directions.

Abstract
A touch input device is provided which can improve considerably an optical transmittance without using dot spacers. A gas cell for a touch input device has: a parallel plate member 2 including two flat plates disposed in parallel and facing each other; a diaphragm 5 for sealing a peripheral portion of the parallel plate member 2 in such a manner that gas is accommodated in a gap between the two flat plates in a state that the two flat plates can conduct relative displacement along opposing directions; and a frame 7 for holding the peripheral portion of the parallel plate member 2 in such a manner that the two flat plates can conduct the relative displacement. In this invention, best touch sense is realized by utilizing elasticity of gas. A further feature resides in that the touch sense can be adjusted freely by a simple method. Each switch element adopts an electrostatic induction method. With this method, an ON/OFF operation of a switching circuit and a selection operation of a switch position can be conducted independently. An ON/OFF mechanism can be shared by all switches irrespective of the number of switches.
