反射形充電スイッチ。(1) A reflective light type that operates by housing the light emitter and light receiver in the first case, and reciprocates the light from the light emitter via a reflector, and intercepts the detection object along the way. In the switch, polarizing filters whose polarization planes are orthogonal to each other are attached to the front surfaces of the light emitting part and the light receiving part, respectively, and
The reflective charging switch is characterized in that the reflecting plate is a recursive reflecting plate whose incident direction and reflected direction are parallel and which converts the plane of polarization by 90°.
