ABSTRACT:
A cassette case adapted to be placed in the cassette recess of a video player/recorder. A cleaning ribbon is mounted in the case and is moved outwardly by tape-guides of the player/recorder to engage the video head and audio head of the player/recorder. To cause the cleaning ribbon to retract after the cleaning operation, there is provided a shut-off ribbon, operated by the drive spindle of the player/recorder, with the shut-off ribbon cooperating with the light/photocell already in the player/recorder. A tension ribbon is connected to the cleaning ribbon to move the cleaning ribbon out of engagement with the video playing/recording head and audio head to its retracted position.
