えること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 cabstern motor forward/reverse rotation signal, a reel motor forward/reverse rotation signal, a capstan motor brake signal, and a video tape recorder mode display signal, for forward and reverse directions. When switching from picture search mode to normal playback mode, the capstan motor is braked by the combination of the capstan motor forward/reverse rotation signal and the capstan motor brake signal, and when switching from normal playback to steel playback, the reel motor is braked. In an additional circuit for reverse direction playback of a video tape recorder that drives a take-up reel in a rotating state to eliminate tape slack, a reverse playback switch, a forward and reverse rotation signal of the capstan motor, a forward and reverse rotation signal of the reel motor, A capstan motor brake signal, a mode display signal, and a reverse direction reproduction command signal from the switch are input, and the capstan motor forward/reverse rotation signal is shaped based on the capstan motor brake signal to cause the capstan motor to rotate forward/reverse. The combination of the signal and the capstan motor brake signal applies a brake to the capstan motor when switching from the forward and reverse peak char search modes to reverse playback, and also brakes the capstan motor only when the mode display signal is in the playback state. Based on the direction command signal, the forward and reverse rotation signals of the capstan motor and reel motor are set to a reverse rotation state, and when switching from reverse direction playback to still playback, the reel motor is set to a reverse rotation state and the supply reel is driven to eliminate tape slack. An additional circuit for reverse direction reproduction, characterized in that it is equipped with a gate circuit for reproducing data in the reverse direction.
