<p>PURPOSE:To obtain a VTR device that can reduce the power consumption and prevent the failure of picture recording, by installing a circuit which cuts off the electric power of a device and its accessory devices in the stop or pause mode and at the same time delays the start of working until a stable state is obtained. CONSTITUTION:In the case of monitor cutting in which a scerren disturbed in the reproduction time is cut, a stop signal (a) is applied and then a unloading end signal (c) is applied. Then immediately a power supply cutoff signal (d) is set at ''L'' to cut off a nonstabilized power supply output B1 and a stabilized power supply output B2 which are supplied to a reproducer and a video camera. When the stop mode is released, the electric power of B1 and B2 are supplied immediately to each part. Then the working command to each part is delayed by a microcomputer 3 until each part becomes stable. In the case of the recording of a picture, a magnetic tape for reverse joint shooting is rewound by a prescribed extent with application of a pause signal (b). After this, both B1 and B2 are cut off.</p> |
