ABSTRACT:
An optical position detection device is formed by an optical sending and receiving unit, which has a sender with associated transmission optics and a receiver arranged at a given distance or position from the sender with associated reception optics, and an optical lightguide unit. The two units can move relative to each other and are configured so that, when they are at the given distance or position relative to each other, a light beam emitted from the sender of the transmission optics is directed to the reception optics.
