を特徴とする逆方向再生の為の付加回路。[Claims for Utility Model Registration] Equipped with a system control circuit that outputs a capstan motor forward/reverse rotation signal, a reel motor forward rotation signal, a capstan motor brake signal, and a video tape recorder mode display signal, In an additional circuit for reverse playback of a video tape recorder, the capstan motor is braked by a combination of the capstan motor forward/reverse rotation signal and the capstan motor pre-quick signal when switching from the picture search mode to the normal playback mode. , the capstan motor by inputting the reverse direction playback switch, the capstan motor forward/reverse rotation signal, the reel motor forward/reverse rotation signal, the capstan motor brake signal, the mode display signal, and the reverse direction playback command signal from the switch. The capstan motor forward/reverse rotation signal is shaped based on the brake signal, and by the combination of the shaped capstan motor forward/reverse rotation signal and the capstan motor brake signal, the forward and reverse picture search modes are switched to reverse playback. a gate circuit that applies a brake to the capstan motor when the mode is switched, and sets the forward and reverse rotation signals of the capstan motor and reel motor to the reverse rotation state based on the reverse direction command signal only when the mode display signal is in the regeneration state. An additional circuit for reverse direction playback.
