Abstract: A support mechanism for a disk player in which a turntable is supported on a metal plate which is screwed to a resin plate. A carriage carrying an optical pickup and its drive are mounted on the resin plate between the two plates but the carriage is guided by the metal plate. The optical pickup tracks the disk through an opening in the metal plate.
Abstract: A contactless (flying) transducer for scanning a record or recording disc is mounted near the free end of a pivoted arm which is driven in rotation about its pivot by the tangential drive provided by a restrained nut on a threaded motor-driven spindle. A pin extending fron the nut slides without play in a lengthwise groove at the free end of the arm. Rapid operation of the electric motor makes it easy to shift from one part of the record to another and slow movement makes it easy to register precisely with a track. Still finer movement is possible electrically by shifting the transducer on the arm.
Abstract: An apparatus for reproducing information signals recorded in spiral or coaxial tracks of a record disc includes a pick-up device operative, upon scanning of a track of the disc while the latter is rotated, to reproduce the information signals recorded in the scanned track; a driver for rotating the record disc relative to the pick-up device; a tracking device for controlling the tracing of the tracks by the pick-up device; a transporting device for bodily moving the pick-up device in a radial direction in respect to the axis of rotation of the record disc and thereby normally determining the tracks to be scanned by the pick-up device; and a controller selectively operative for causing the pick-up device to intermittently trace nonadjacent groups of tracks so as to intermittently reproduce the information signal recorded in the nonadjacent groups of tracks, respectively.
Abstract: A pickup arm driving control system in record disc players with repeat playback function. The driving control system can drive the manipulation of a tone arm in such a manner that only an optionally selected portion is repeatedly reproduced.
Abstract: An electronic timepiece having an A.M. and P.M. display function. The characters A or P are displayed during time setting or correction by one discretionary display element of a plurality of display elements normally used for displaying time.
