ABSTRACT:
The stylus arm carriage is provided with a slidably-mounted plunger. When the carriage is driven to an off-record home position, a portion of the front wall of the player engages a protruding end of the plunger to drive it in. The other end of the plunger engages a carriage-mounted stylus cleaner mechanism to lock it in place while the carriage is disposed at the home position to prevent the possibility of accidental contact between a pickup stylus and the cleaner mechanism.
