Abstract: RCA 75,322 In a video disc player, the turntable spindle is held in a raised position such that it is maintained in engagement with the record center hole when the turntable is lowered to transfer a spinning record from the turntable to the receiver pads. A mechanism, responsive to the insertion of an empty jacket into the player, retracts the spindle to allow the insertion of the jacket into the player free from interference with the spindle.

Abstract: RCA 74,362 STYLUS CLEANING APPARATUS FOR VIDEO DISC PLAYER A stylus cleaner arm is pushed back to a retracted position when a record-bearing caddy is inserted into the player to load an enclosed record therein. The cleaner arm is held in the retracted position by the retained spine upon subsequent jacket withdrawal. The cleaner arm follows the caddy as it is withdrawn from the player until it engages a latch plate, which arrests the cleaner arm at an intermediate position. The stylus lifter gently drops a pickup stylus on the cleaner arm occupying the intermediate position as the caddy is further withdrawn from the player. The latch plate frees the cleaner arm to swing back to a standby position thereof during still further withdrawal of the caddy, thereby passing the cleaner arm underneath the stylus to wipe it clean. The stylus is raised away from the cleaner arm when the caddy is withdrawn from the player.
