Claims

[Scope of utility model registration request]

A tape cassette containing a magnetic tape wound on a reel is inserted into the cassette holder, and the downward movement of the cassette holder guides the tape cassette to a predetermined position in the main body of the Wi-Q recording/playback device, while the upward movement of the cassette holder guides the tape cassette In a magnetic recording/reproducing device that guides a tape cassette to a take-out position, a tension arm is swingably supported on the floor of the magnetic recording/reproducing device, and a tension arm is installed at one end of the tension arm to guide the tape cassette to a predetermined position. A tension post that can come into contact with the tape, an elastic part stretched on a tension arm to bias the tension post toward the magnetic tape, and a tension arm that works in conjunction with the tension arm to maintain tension when the magnetic tape is in a slack state. 1. A tape jamming prevention device comprising: a sensor for detecting the position of the arm; said sensor generates an output signal for inhibiting upward movement of a cassette holder when the magnetic tape is in a slack state.
