１項記載の光透過型ロータリーエンコーダ。[Claims for Utility Model Registration] (1) Light transmitted through the transparent parts 2 is transmitted by rotation of the pulse scale 1 in which the transparent parts 2 forming the code pattern C along the circumferential direction are formed at predetermined intervals. A light-transmitting rotary encoder configured to output intermittent optical pulse signals according to the rotation angle thereof includes a light-emitting element 6 that irradiates light onto the transparent portion 2 from both sides of the pulse scale 1; , and the end face 7a of the light-receiving optical fiber 7 that receives the light transmitted through the light-transmitting part 2 are arranged to face each other, and in this state, the light-emitting element 6 and the light-receiving optical fiber 7,
A light transmission type rotary encoder characterized in that it is integrally attached and fixed to a housing 5. (2) The light transmission type rotary encoder according to claim 1, wherein the power supply line 6a of the light emitting element 6 is bent in the same direction as the wiring direction of the light receiving optical fiber 7. .
