出機構。 The light receiving section detects the reflected light generated by irradiating the position detection uneven parts provided alternately and continuously on the outer circumferential edge of a circular code wheel that is attached to the rotating shaft with a common axis line. In a rotation detection mechanism that further converts reflected light into an electrical signal to detect the rotational status of a rotating shaft, the shape of the concave part of the position detection concave and convex part of the code wheel is adjusted so that the light incident into the concave part is directed to the light receiving part. A rotation detection mechanism for a rotating shaft characterized by having a shape that reflects the light in a direction that does not reach the user.
