ABSTRACT:
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 The cleaner arm follows the caddy as it is withdrawn from the player until it engages a latch plate, which arrests the cleaner arm at an intermediate position.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lifter gently drops a pickup stylus on the cleaner arm occupying the intermediate position as the caddy is further withdrawn from the player.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 The stylus is raised away from the cleaner arm when the caddy is withdrawn from the player.
