Claims (1)
群を相対向させて配置し、各発光素子および受光
素子対により表示画面に沿つて形成される光路の
遮断から表示画面上の座標位置を決定するタツチ
式座標入力装置において、発光素子および受光素
子の配列近傍に吸込み口を配置した集塵装置を設
けたことを特徴とする指タツチ式座標入力装置。 A light-emitting element group and a light-receiving element group are arranged facing each other around the periphery of the display screen, and the coordinate position on the display screen is determined by blocking the optical path formed along the display screen by each light-emitting element and light-receiving element pair. What is claimed is: 1. A touch-type coordinate input device, characterized in that the touch-type coordinate input device is provided with a dust collector having a suction port disposed near an array of light-emitting elements and light-receiving elements.
