Abstract
A method of manufacturing a photo interrupter includes forming a frame including a first frame part and a second frame part which are disposed at an interval to be facing each other, mounting at least one light-emitting element on a first board and attaching the first board to the first frame part of the frame, mounting a light-receiving element on a second board and attaching the second board to the second frame part of the frame, the light-receiving element being mounted on the second board to be facing the light-emitting element so that the light-receiving element receives light emitted from the light-emitting element, and providing a positioning member on the frame by integrally forming the positioning member with the frame.
