Abstract
The in-arm stylus cleaner includes a cleaner arm mounted for to-and-fro motion in the stylus arm carriage. To clean the stylus, the cleaner arm is retracted, the reproducing stylus is raised back up into the carriage arm, the cleaner arm is freed to allow a wiping element mounted thereon to sweep the stylus tip, and the stylus is then gently lowered onto a turntable-disposed record to resume playback operations.
