Opto electric scanner with illumination device and transducer - has light exit aperture(s) in unit centre and inlet(s) at edge

The optoelectric scanner for an original picture or document has a device illuminating an image point and receiving the reflected light from it. The receiver is an optoelectric transducer. The illumination device and transducer are so combined, that the light exit aperture(s) is in the unit centre, while the inlet aperture(s) is at its edge. In the centre of an encompassing ring (6) of the cable a semiconductor type of light emitter (7) is found, while around the ring itself six semiconductor type light detectors (8-13) are arranged. The cable conducts the detector outputs simultaneously to an amplifier and to the emitter (7) via divided leads of the supply voltage.
