Abstract

PURPOSE: To apply a tape with back tension while determining the run direction of the tape in accordance with the magnitude of torque applied to right and left motors in only one direction by exercising on-off control over transistor connected in series to constant-current source transistors with regards to a driving circuit having right and left reels equipped with the motors respectively.
CONSTITUTION: To series connection parts of transistors Q1 and Q2, and Q3 and Q4 operating as constant-current sources, the bases of Q9 and Q10 for driving right motor M1 and left motor M2 respectively are connected, and Q5 for reverse reproduction and Q6 for normal reproduction are connected in series to Q3 and Q4 respectively. Then, Q5 and Q6 are turned off and on respectively for normal reproduction and on and off for reverse reproduction.
