Claims

[Claims for Utility Model Registration] (1) Light transmitted through the transparent portions 2 is transmitted through the rotation of the pulse scale 1 in which the transparent portions 2 forming the code pattern C along the circumferential direction are formed at predetermined intervals. In an optical rotary encoder configured to output optical pulse signals intermittently according to the rotation angle,
The light emitting optical fiber 6 and the light receiving optical fiber 7 are
An optical path is provided toward one side or the outer periphery of the pulse scale 1 from the same direction, and allows the light emitted from the light emitting optical fiber 6 to be reflected by the reflectors 8, 9a, and 9b and input to the light receiving optical fiber 7. formed,
The light emitting optical fiber 6, light receiving optical fiber 7, and reflectors 8, 9a, and 9b are integrally attached and fixed to the housing 5, and a pulse scale 1 is disposed at a position that interrupts the optical path. An optical rotary encoder characterized by: (2) A pulse scale 1 in which transparent parts 2 forming a code pattern are formed at predetermined intervals along the circumferential direction.
In the optical rotary encoder, the light transmitted through the light-transmitting part 2 is interrupted by the rotation of the optical fiber 10, and a light pulse signal corresponding to the rotation angle is output. ,1
2 and 13 and enters the optical fiber 10 again.
An optical rotary encoder characterized in that reflectors 11, 12, and 13 are integrally attached and fixed to a housing 5, and a pulse scale 1 is disposed at a position that interrupts the optical path.
