Abstract

The in-arm stylus cleaner includes a cleaner arm mounted for to-and-fro motion in the stylus arm carriage. A cleaning element, comprising a piece of compliant sheet, has one edge secured to the cleaner arm such that the cleaning element extends away from the cleaner arm substantially at right angles thereto. 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.
