  • Patent number: 4079944
    Abstract: The cueing device, to facilitate the operation of bringing the stylus of a phonograph pickup into engagement with a selected unrecorded zone of a phonograph record, so that the next recorded zone will be played, may include a light source mounted on the pickup for providing a light beam to be reflected from the face of the record to a photoelectric device on the pickup. A utilization device, preferably including a visual signal mounted on the pickup, is operated when the reflected light beam is received by the photoelectric device from the unrecorded zones. The light source, the photoelectric device and the light path therebetween are preferably mounted in a transverse perpendicular plane, transverse to the record grooves and generally perpendicular to the record face. The light reflected by the unrecorded zones is given a polarization in a plane transverse to such transverse perpendicular plane.
