摘要：
A wireless input device for computer comprises a pen-type input device having a source of light capable of transmitting pulses. The wireless input device further comprises an input device body including two angle detecting section, each having a light receiving element constructed so that it is rotated to the direction of the incident angle of incident light when the incident light from the source of light is detected, and a calculating section for calculating the position of the pen-type input device from the two incident angles detected by the two angle detecting sections.
