Title:

PHOTOELECTRIC CONVERSION TYPE PULSE ENCODER

Document Type and Number:

WIPO Patent Application WO/1982/002945

Kind Code:

A1

Abstract:

In a photoelectric conversion type pulse encoder having incident light units (13, 13'), a rotary slit plate (12) provided with a lattice plate for receiving light from the incident units, a stationary slit plate (11) provided with a lattice plate disposed to face the above lattice plate, and light receiving units (14, 14') disposed under the stationary slit plate, light is supplied from a light emitting circuit through an optical fiber (17) to the incident light units (13, 13'), the light received by the light receiving units (14, 14') is introduced through the optical fiber (17) to a photodetecting circuit, the adjustment for the quantity of light can be thus simplified, pulses responsive to the speed of rotation can be effectively generated, and the speed of rotation can be accurately detected.
