Abstract
A sheet-shaped cleaner including a resilient film and nonwoven cloth consisting of synthetic fibers formed on one side of the film is disposed in opposition to a guide roller. A magnetic tape is sandwiched between the guide roller and the cleaner and with the magnetic surface of the magnetic tape being contacted by the nonwoven cloth of the cleaner. The film of the cleaner is wedged between locking portions of the cassette in order to cause the cleaner to bow in a direction away from the guide roller such that the nonwoven cloth of the cleaner is biased under a low force against the magnetic surface of the tape. Accordingly, foreign matter on the surface of the magnetic tape is removed.
