Abstract: The invention relates to an optoelectronic device (1) for detecting markings affixed to objects by using a transmitter (6) that emits light rays (8), a receiver (11) that receives light rays (10), an evaluation unit (5) and a deflection unit (9) at which the transmitting light rays (8) are reflected and, as a result, are periodically guided inside a predetermined angular range. At least two stationary reflecting units are installed in series after the deflection unit (9). The transmitting light rays (8) are guided over the first reflecting unit inside a first segment &Dgr;&agr;1 of the angular range &Dgr;&agr;, so that these rays periodically scan a first segment of a three-dimensional detection range. Inside of a second segment &Dgr;&agr;2 of the angular range &Dgr;&agr;, the transmitting light rays (8) are guided over a second reflecting unit, so that these rays periodically scan a second segment of the three-dimensional monitoring range.

Abstract: A device for positioning objects in a desired position includes a transmitter for emitting light rays (11), a receiver for receiving light rays and an optical sensor (10) with an evaluation unit. The desired position is scanned with the transmitted light rays (11). The device additionally includes at least one holding device, in which a predetermined number of objects are stored in predetermined slide-in positions. Each slide-in position has a position mark associated therewith. The device furthermore includes a transport system for moving the holding device relative to the optical sensor. The holding device is stopped as soon as a position mark for a slide-in position of a predetermined object is detected by the optical sensor, wherein the predetermined object can be identified with the optical sensor through object marks located on the object.
