載の８ミリビデオテープレコーダ。[Claims for Utility Model Registration] (1) A rotation detection pulse generator that generates a rotation detection pulse having a frequency that is an integral number n times the vertical synchronization frequency during normal reproduction as the capstan motor rotates; A frequency divider circuit that divides the detected pulse by 1/n and outputs the divided pulse, and a phase control circuit that controls the phase of the divided pulse so that it has a constant relationship with the phase of the vertical synchronization signal during normal playback. and an output circuit that forms and outputs a drive signal for intermittently driving a capstan motor to perform frame advance or slow motion playback based on the frequency divided pulse. (2) The transfer control circuit resets the frequency dividing circuit by outputting a reset signal synchronized with the head switching pulse to the frequency dividing circuit only during normal reproduction. The 8mm video tape recorder described. (3) The output circuit includes a flip-flop, a trigger circuit that generates a trigger pulse of a constant period to set the flip-flop in response to a mode designation signal that designates frame-by-frame or slow-motion playback mode, and a frequency-divided pulse. 3. The 8 mm video tape recorder according to claim 1, further comprising a single-direction multivibrator which resets the flip-flop after a predetermined period of time in response to the lapse of a predetermined period of time.
