ABSTRACT:
The stylus cleaner includes a stylus wiping pad holder mounted for motion along a path which is angularly disposed with respect to the carriage path. The location of the holder path is such that the stylus arm carriage engages the holder to drive it away from the record, against the force of a spring, as the carriage is driven toward an off-record rest position. The holder, carrying a stylus wiping pad, follows the carriage as it heads toward the record for playback. A stylus lifting/lowering apparatus located in the carriage is momentarily activated to cause engagement between the stylus with the wiping pad at points beyond the periphery of the record to effect stylus cleaning as the carriage is heading away from the off-record rest position.
