摘要

In a magnetic tape recording and/or reproducing apparatus, a device for giving an alarm sounds when the magnetic tape runs out in a tape reel. The device comprises a tension change sensing element adapted to sense a change in tension of the tape, a sound producing member and a rotating body which keeps on rotating even after the termination of the tape feeding, and is operative in such a manner that when the tape feeding is terminated, the tension change sensing element is displaced as a result of a change in tension of the tape at the end portion thereof, thereby bringing the sound producing member into engagement with the rotating body to produce an alarm sound.
