受光体を配置した帯状体の反射マーク検出装置。In a detection device, a reflective mark is attached to a strip of film or magnetic tape, and a light emitting body that shines a light beam on the reflective mark and a photoreceptor that reads the reflected light are installed. This is a reflective mark detection device for a band-shaped body, in which two photoreceptors are arranged on both sides of a light-emitting body to receive reflected light whose direction changes as the angle of the band-shaped body changes.
