In the coordinate input device for selective input, the optical detection means is installed upright on a printed circuit board provided parallel to the screen of the display, and includes a light emitting element and a light receiving element facing each other with the display in between, and the light emitting element and the light receiving element. The light emitted from the element is deflected by 90 degrees, and the deflected light is
A coordinate input device comprising: a deflection cover attached to the light emitting element and the light receiving element, each having a deflection means for deflecting the light by 0° and making the light incident on the light receiving element; and a filter provided near these deflection covers.
