<p>PURPOSE:To simplify the operation of the user by setting the stop mode automatically independently of the operation of the user when the reproduction of information on a magnetic tape is finished and rewinding the magnetic tape automatically till the start of winding, ejecting the magnetic tape and turning off a power supply automatically. CONSTITUTION:When the reproduction of a video signal is finished, a signal of a black level is reproduced for a prescribed period. When a black level detection circuit 4 detects it that a signal of the black level is reproduced for a prescribed time, a command signal is generated and fed to a control circuit 5. The control circuit 5 controls a mechanism section 6 to set the stop, the rewinding, the tape eject mode sequentially and when the watching of the content of information of a magnetic tape 1 is finished, the magnetic tape 1 is rewound to the start of winding and ejected automatically. The control circuit 5 is provided with a clock section and as soon as the tape ejection is started, the time measurement is started. When the measured time reaches a prescribed time and a power switch 8 is turned off.</p> |
