ークを取付け、この反射マークに光線を当てる発光体と
反射光を読み取る受光体を設けた検出装置において、帯
状体の反射マークに光を当てる1個の発光体の両側に帯
状体の角度変化により方向の変る反射光を受ける2個の
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.
