Object, e.g. files, locating and recognizing device, includes optical waveguides arranged at the edge area, each waveguide having an entry region into which light beam output by evaluation unit is received

摘要

An evaluation unit is in active communication with the device (3) for receiving and sending out signals. An optical waveguide (7) is arranged at the edge area (9) of the device. Light beams output by the emitter of the evaluation unit are received at the entry regions along the ends (11) of the waveguides that are condensed towards the other end (10) forming an optical waveguide bundle (14).
