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 a record retaining spine upon subsequent jacket withdrawal. The cleaner arm follows the caddy as it is withdrawn from the player after record playback. The cleaner arm engages a switch which actuates a stylus lowering device to lower a pickup stylus onto a cleaning pad disposed on the cleaner arm. The cleaning pad wipes the stylus as the cleaner arm swings back. A timing device deenergizes the stylus lowering device after a preselected time interval to lift the stylus away from the cleaning pad.
