したことを特徴とする光学式座標入力装置。 Two sets of rectangular frame-shaped optical elements each having a large number of light-emitting elements and light-receiving elements arranged in rows are provided, and each of the above-mentioned light beams is provided in front of two display devices arranged in parallel with each other's display surfaces tilted inward. The coordinate position on the display surface of each display device can be determined by attaching one set of element groups and detecting the position where the optical path formed between the light emitting element and the light receiving element of each optical element group is interrupted. In the optical coordinate input device for input, the above 2
1. An optical coordinate input device characterized in that mutually adjacent substantially parallel sides of a set of optical elements constitute a light emitting element array or a light receiving element array.
