Abstract

A wireless input device for computer comprises a pen-type input device having a source of light capable of transmitting pulses. Two light receiving elements are provided and these light receiving element are disposed for detecting an incident angle of light inputted from the source of light. The wireless input device also has an input unit body having an operational unit for calculating the position of the pen-type input device from the amounts of light detected by the two light receiving elements.
