Claims

[Scope of utility model registration request]

A code wheel is rotatably held in a case, and reflective surfaces and non-reflective surfaces are formed alternately at a constant pitch in the circumferential direction on the periphery of the code wheel, and two incident optical fibers arranged in parallel and these holding the output optical fibers disposed between them in the case, bringing one end surface of each of the optical fibers into contact with a protrusion provided on the case so that they are aligned and facing the peripheral edge of the code wheel; A rotary encoder characterized in that a light emitting element facing the other end surface of the output optical fiber and a light receiving element facing the other end surface of each input optical fiber are mounted in the case.
