を特徴とする透過型光センサ。Transmissive type that includes a light emitting part, a light receiving part into which light from the light emitting part is incident, and a light shielding plate that enters the optical path between the light emitting part and the light receiving part and blocks the light to turn off the output. In the optical sensor, a light reflecting surface is formed on the end face of the light shielding plate on the optical path entry side, and immediately before the output of the transmission type optical sensor is turned OFF due to the movement of the light shielding plate and the light is blocked, the light from the light emitting part is A transmissive type characterized in that the output ratio of the transmissive optical sensor at 0N10FF is increased by reflecting the diverging light on the reflective surface and making it incident on the light receiving section, thereby increasing the resolution of the detection position by the light shielding plate. light sensor.
