摘要:
A photo-interrupter includes a light-emitting-side internal device provided with a light-emitting chip and formed by molding, and a light-receiving-side internal device provided with a light-receiving chip and formed by molding. The light-emitting-side internal device has a light output face, and the light-receiving-side internal device has a light input face. The light-emitting-side internal device and the light-receiving-side internal device are held by a casing, such that the light output face and the light input face are opposite to each other with a gap interposed therebetween. The light output face and the light input face are respectively disposed in first and second slits formed in the casing. The light output face and the light input face are respectively flush with surfaces of the casing around the first and second slits.
