Abstract
The apparatus for inputting coordinates has a support plate including a coordinate input plane for inputting a coordinate position, an optical unit is formed by integrating a light source and a light receiver. The light source emits light which is substantially parallel to the coordinate input plane. A reflecting section reflects the light emitted from the light source. The optical unit is embedded in the coordinate input plate by the use of a frame, an optical unit retaining plate and a screw.
Claims22
An apparatus for inputting coordinates, the apparatus comprising:
- a coordinate input plate including a coordinate input plane for inputting a coordinate position;
- a light source section which emits light that is substantially parallel to the coordinate input plane;
