Abstract
PURPOSE: To control the torque of a reel motor, by detecting running direction and running quantity of a tape by rotation of capstan and by subjecting them to addition and subtraction.
CONSTITUTION: A tape is linked with capstan 1 without slip. Reel 2 is used for roll- up, and reel 3 is used for supply, and they are driven through buffer 4 or 5 by capstan 1. Tape quantity sensor 6 or 7 is arranged in buffer 4 or 5, and reel motors 8 and 9 of reels 2 and 3 are so driven that a proper tape quantity is always stored in buffer 4 or 5. Rotation of capstan 1 is detected optically and is given to integrating counter 11 for the tape running quantity. Then, torque control circuit 12 is operated according to contents of integrating counter 11 to control the torque constant of reel motors 8 and 9.
