ABSTRACT:
A cassette cleaner adapted to be positioned in a cassette receiving recess of a video player/recorder. A cleaning ribbon is mounted in the cassette cleaner, and guide members of the video player/recorder carry the cleaning ribbon outwardly into cleaning engagement with the rotating head of the player/recorder. The cassette cleaner has a stationary locating element which restrains outward movement of a portion of the ribbon so that the ribbon engages the peripheral surface of the rotating drum that carries the head member along two contact locations of relatively short arcuate length. This reduces the frictional engagement of the ribbon relative to the rotating drum.
