Claims

[Scope of utility model registration request]

A cleaning tape cassette detection means for detecting that a cleaning tape cassette is loaded and a tape for detecting tape running in a magnetic recording/reproducing device equipped with a tape running release means for releasing the running of the tape by inputting a release signal. a running detecting means; a timer circuit operation commanding means for starting the operation of a timer circuit based on the detection outputs of both the detecting means; and a release signal to the tape running canceling means after a predetermined time set as an appropriate cleaning time. A magnetic recording/reproducing device characterized by being provided with a timer circuit for output.
