Abstract

PURPOSE: To eliminate relative, positional slippage among a luminous portion and lignt receiving portions and heighten the accuracy of detection, by a means wherein a photoelectric transducer is used which forms the luminous portion and the light receiving portions on the same semiconductor substrate.
CONSTITUTION: Reflecting portions 2 and non-reflecting portions 3 are made up on a surface of a body 1 moving in the arrow head direction at fixed pitches l1. A photoelectric conversion semiconductor device 6 for detecting the motion of the body consists of a compound semiconductor substrate in CaAs0.62P0.38, etc., a luminous diode 7 is mounted to the central portion, light receiving diodes 81, 82 are installed at the both sides of the luminous diode 7, and the reflected light of light radiated to the body 1 in motion from the luminous diode 7 is received by means of the light receiving diodes 81, 82, and extracted as electric signals.
