トテーププレーヤ。[Scope of Claim for Utility Model Registration] A magnetic tape cassette case is set on a take-up reel stand and a feed reel stand, and the magnetic tape inside the cassette case is fed at a constant speed by constant rotation of a capstan to record information. In a cassette tape player that plays back magnetic tape, there is a rotational speed detection section that detects the rotational speed of the take-up reel stand while the magnetic tape is being fed at a constant speed, and when the rotational speed detection section detects an increase in the speed of the take-up reel stand. The cassette case is characterized by being equipped with a control unit that determines that the magnetic tape is wrapped around the capstan and outputs an eject signal, and an eject mechanism that ejects the cassette case based on the eject signal output by the control unit. cassette tape player.
