Optical encoder, motor driver and image forming apparatus |
摘要 |
An optical encoder includes a light emitting unit that emits parallel light onto a plurality of marks that are arranged on an object such as a rotor or a belt, at a predetermined interval in a moving direction of the object, and a light receiving unit that receives light modulated by the marks. The parallel light is generated by a collimating lens.
