<p>PURPOSE:To prevent the parallax to be generated due to the glass or the like on the display position of liquid crystal panels or CRTs which makes the coordinates located further than the position pointed by a pen or the like pointing the coordinates and to make the position to be seen and the position to be pointed by the pen come closer. CONSTITUTION:Plural light guides 2 are arranged on the twodimensional surface with their surfaces contact with a light emitting body 3. A light emitting part 5 makes the light emitting body 3 emit light by a cathode ray 4. The light emitted from the light emitting part 5 advances in the direction nearly vertical through the right guide 2 like a light 6 and does not leak in the other direction. Thus, the surface of the light guide 2 seems like shining. Therefore, the visible display part of the coordinate input device with the light guide 2 arranged on the surface of the display part moves to the surface so that the surface seems like shining and being reflected or transparent. Thus, the parallax between the coordinate position pointed by the coordinate pointing part and the visual display position can be eliminated.</p> |
