<p>PURPOSE:To confirm video recording by rewinding a tape in a predetermined time is interlocking with an operation switch, reproducing the rewound tape after rewinding and bringing the mode automatically to the video recoding state. CONSTITUTION:AND circuits 2d, 2d combine outputs Q0-Q7 of a counter 2c to set 3 kinds of pulses h, i, j generated for a prescribed time after a switch 1 is depressed. The 3 kinds of pulses h, i, j are used as start signals of three kinds of modes, such as rewind/reproduction/ video recording modes. Thus, only when the switch 1 is turned on, a timer circuit 2 is operated to output rewinding-reproduction-video recording mode start signals h, i, j. Then the video recording is confirmed in a time as short as nearly 20sec after the switch is depressed by having only to depress one switch.</p> |
