ABSTRACT:
A disc loading device used in a video disc player in which a turntable is held rotatably at a certain position, comprises a caddy-receiving plate, a driving mechanism, and a linkage mechanism. The caddy-receiving plate has an opening through which said turntable can be protruded and has at both lateral edges a guide means adapted to guide horizontally a caddy into said plate. The driving mechanism is provided at each side of said plate adjacent to a caddy-inserting opening and includes a bracket mounted fixedly to the bottom of a body of the player, a first operating means mounted to said bracket formed with a cam adjacent to said caddy-inserting opening, said cam having an inclined surface facing towards said caddy-inserting opening and contacting with the proceeding end of the caddy at insertion of the caddy, a damper mounted to the connection between said bracket and the first operating means, and a second operating means mounted pivotally to said first operating means and adapted to transmit the movement thereof to the plate. Linkage mechanism is connected to both sides of said plate and driving mechanism and adapted to change a rotational movement from said driving mechanism into an upward and downward movement of the plate, while being maintained horizontally, between a position lifted to be in a common plane with said caddy-inserting opening to permit the caddy to be inserted into the plate and a position lowered to permit the disc to be seated on the turntable at removal of the caddy from said caddy-inserting opening.
