Abstract:
A coordinates inputting apparatus comprising:a substantially flat surface; a plurality of light sources positioned at specified angles to said flat surface by a bracket, wherein each of said plurality of light sources output a light flux that travels along said flat surface; at least one reflective section that recursively reflects the light fluxes output from said plurality of light sources; and a plurality of light-receiving sections that receive the light flux reflected by said reflective section, which plurality of light-receiving sections detect whether the output light flux is shielded; a bracket holding said plurality of light sources; and wherein said plurality of light sources output respective light fluxes onto a specific position on said flat surface and said plurality of light-receiving sections receive the light fluxes which are output from said plurality of light sources, reflected from said flat surface, recursively reflected by said reflective section, and once more reflected by said flat surface.
