<p>PURPOSE:To facilitate a tape cassette taking out in the state of a magnetic tape being rewound to a starting end part by providing the means producing the specified period information signal informing of the magnetic tape being rewound to the start end part. CONSTITUTION:When the lead tape at a magnetic tape start end part is detected by the output signal from a photocoupler 2a, a lead tape detection circuit 3 feeds a signal to an informative signal generation circuit 4, the informative signal in the specific audible frequency for fixed period is produced and a fixed period alarm sound is generated from the voice generator of a speaker, buzzer, etc. by this informative signal. The state of the magnetic tape being rewound to the start end part is discriminated and when the auto-repeating motion is released with the stop operation, the magnetic tape in the tape cassette 1 is held in the state of being rewound to the start end part.</p> |
