<p>PURPOSE:To simplify the check of picture recording, by reproducing a video tape reversely for a prescribed time interlocking with the operation of a switch provided separately, recovering a system to a picture recording operation after completing a reverse reproducing operation, and prohibiting control operations from various kinds of operating switches during the reverse reproducing operation. CONSTITUTION:A reverse reproducing signal output circuit 5 receiving an inverse signal, the inverse of A, outputs a reverse reproducing signal B, and its inverse signal, the inverse of B, and a control circuit 10 receiving the signal B, rotates a capstan motor and a reel motor in a reverse reproducing direction, then a VTR goes to a reverse reproducing mode. The time of reverse reproduction is set at a timer circuit 6, and a signal C, receiving the inverse signal, the inverse of B, goes to a low level only for a time set in advance. A recording signal output circuit 7 receiving the signal C, outputs a recording signal D, and the control circuit 10, receiving the reverse reproducing signal D, generates a recording mode. Also, the reverse reproducing mode is generated after depressing a recording check switch 1, and until the mode is recovered to the recording mode, an operation prohibiting transistor 9 is turned off, thereby, the operations of the recording check switch 1, and the various kinds of operating switches 8 are prohibited.</p> |
