タ。A photodetector in which a light source and an optical sensor are respectively disposed with a required gap on both opposing inner surfaces of a groove-shaped structure so as to form a detection optical path, and the detection optical path is formed in the gap using the groove-shaped structure as a guide. It is characterized in that it includes a light-shielding actuating piece that is inserted so as to block the light and is rotatably supported on a shaft, and that passing and blocking of the detection light is performed by displacing a light-transmitting part provided in advance on the light-shielding actuating piece. Photo-interrupter.
