A loading device for a recording and/or playback apparatus, for example, a record-disc player or a tape cassette apparatus, comprises a movable loading support onto which a holder containing a record carrier can be slid by feed rollers driven by a motor. The loading support is slidably supported between two fixed, parallel, vertical guide plates by pins on the support sliding in L-shaped guide slots in the guide plates, each slot having a vertical section extending downwardly from a horizontal section. Slidably supported on the outer sides of the guide plates for horizontal movement in vertical planes parallel to the planes of the guide plates are two drive plates having inclined slots in which the pins on the loading support slidably engage. By cooperation between the inclined slots and the pins the drive plates can move the loading support, guided by the L-shaped slots in the guide plates, along a horizontal path and down a vertical path to bring the record carrier in the holder on the loading support to a playing position. Each drive plate is arranged to be driven by the motor through a transmission which includes a rack and pinion and which comprises means whereby the transmission is disengaged when the drive plate is in the rest position and engaged by movement of the drive plate away from this position. Stops are provided on the loading support to limit the movement of the holder onto the support by the feed rollers, and these stops are so arranged that after abutting them the holder is moved further by the feed rollers and through the loading support moves the drive plates away from their rest positions to effect engagement of the transmissions between the motor and the drive plates. |
