Zusammenfassung:	An optoelectric measuring device (11) for angles of rotation has a rotatable carrier (12) with a track (13) of marking elements (14), and a scanning device with a device (22) for transmitting and receiving radiation. Two channels are provided for two scanning signals offset by 90 electrical degrees. The reflection behaviour of the marking elements (14) differs from that of the carrier surface. The scanning device has two light guides (18, 19) whose scanning ends (20) are adjacent to the track (13). The other end thereof is connected to the transmitting/receiving device (22). The scanning ends (20) are arranged in a common holder, in particular a tube (16). This results in simple adjustment.
