ABSTRACT:
In a relative angle detecting device, plural received light outputs are subjected to time division. Received light detection voltage is shifted by a phase shifter and sampling pulse is formed, and peak detecting means holds peak value of received light output based on the sampling pulse. In a CPU, peak value of each voltage is stored in a memory, and the stored value is operated thereby information regarding relative position between a light source and a light reception element is operated. Utilizing the time division, each received light detection voltage can be processed in the same condition, and the peak value of each received light output can be detected with high precision.
