  • Patent number: 4479210
    Abstract: For loading a record disc on the turntable of a record-disc player, a loading device is provided which comprises a movable loading support for supporting a holder containing a record disc. 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 deposit the record disc supported on the loading support on the turntable.
