  • Patent number: 4979161
    Abstract: In a disc-record player which comprises a resiliently support subframe (5) which carries a turntable (6) and a read means (9) a loading device (14) for loading a disc (15) into the record player comprises a servo means (53) which comprises a plurality of control elements for controlling the movements of the loading device (14). An insertion control element (52) cooperates with a transfer device (17, 29) to guide the disc (15) towards the turntable (6). A lift control element (57c) cooperates with the transfer device (17, 29) to control the movement of the disc (15) towards the turntable (6). A clamping-member control element (71b, 72b) controls at least two clamping members (26) of the transfer device (17, 29) which members hold the disc (15) during loading, and causes the clamping members (26) to be disengaged from the disc after the disc has been lowered onto the turntable (6).
