ABSTRACT:
In a cassette tape device having tape guide means movable around a tape guide drum, the operating time of the tape guide means is measured to actuate a protecting circuit to stop the tape drive motor if the operative time of the tape guide means exceeds the estimated operating time, as such excessive time would be indicative of trouble in the guide means.
