Abstract

Abstract There is described, among other things, a novel record player of the slot-loading type in which a phonograph record disc is supported in a playing position on a turntable rotatably driveable at a selected speed about an axis. The disc, in its playing position, is engageable with a stylus supported by a transducer cartridge held in a carriage which is movable along a line radially of the turntable above the turntable in response to tracking engagement of the stylus in the spiral groove of the phonograph record disc. The turntable is movable along such axis into and out of a playing position thereof, and the turntable and the carriage are disposed in an enclosing housing. According to this invention, the housing includes a door which is closed when the turntable is in its playing position. The door includes record support members, accessible in an open position of the door, for receiving and supporting a record and for disposing a supported record between the turntable and the carriage coaxially above the turntable when the door is in its closed position. The record-supporting members are positionally adjustable for receiving and supporting at different times records of different diameters. The record support elements are power driven between their various adjusted positions. The drive mechanism associated with the record support elements is operable when the door is in its open position. Also, a power mechanism is provided for moving the door between its open and closed positions.
