Abstract

PURPOSE:To remarkably reduce the number of terminals to many items, by using the multiswitching property of conductive rubber and forming the multidimensional matrix structure, in the multi-item input device used for kanji (chinese character) input device. CONSTITUTION:Conductive rubber 4 which is laminated on the double-sided printed board 1 and is in contact with the whole surface of X and Y electrodes 2, 3 of matrix structure, is provided, a flat electrode 5 is laminated on the rubber 4, and character film 7 is provided thereon via the supporting film 6. When the position on which desired character is printed on the film 7, is depressed with a finger, the rubber 4 is conductive, and the electrodes 2, 3 are conductive together with the flat electrode 5. Thus, the number of terminals to many items can remarkably be reduced by forming the multidimensional structure of conductive rubber.
