Claims

[Claims for Utility Model Registration] A cleaning tape that is wound between a pair of tape reels and can be rewound freely, and a cleaning tape that can be guided from the tape reel to a position facing a magnetic head so that it can run. The cassette case is set in a tape drive section of a tape recorder, and the tape reel is rotationally driven to bring the cleaning tape into sliding contact with the magnetic head, and the cleaning tape is moved into sliding contact with the magnetic head. A cleaning cassette for a tape recorder that cleans a head includes a pair of rollers respectively disposed between the guide roller and the tape reel, and a roller supporting the rollers and extending along the rollers and the guide roller. and a wet cleaning roller that presses the cleaning tape against one of the rollers of the slide member to clean the tape reel. a swing arm that presses the cleaning roller against one of the rollers provided on the slide member according to the rotational direction of the swing arm; While the cleaned cleaning tape is fully wound around the other tape reel, the swing arm is driven to swing in accordance with the rotational direction of the tape reel, and the roller of one of the slide members a first guide groove provided on the gear including a cam means to be brought into contact with the gear; a first guide groove provided on the gear such that the gear gradually ascends when the gear rotates in one direction; and a first guide groove that gradually descends when the gear rotates in the one direction. A cleaning cassette for a tape recorder, comprising: two guide grooves; and a stopper member that can selectively engage the first and second guide grooves.
