Abstract

PURPOSE:To hold tape tension in a prescribed value by driving a reel motor by a driving current proportional to or inversely proportional to the rotation speed of the reel motor. CONSTITUTION:A frequency generator 241 is coupled with a reel DC motor 221 coupled with a supply reel 10, and a rotational frequency N1 is detected by a driving circuit 261 through a frequency signal Nd1. When the rotation speed N1 is greater than a constant value, a motor torque proportional to a driving current Im is adjusted to a value inversely proportional to the turning speed N1 to make tension T2 constant for a stationary run, and when a turning speed N2 is less than the constant value, the driving current Im is adjusted to a value proportional to the rotation speed N1 for stop or starting. Therefore, the dirving current Im is ceased in stop mode and its maximum value is limited to prevent over-tension. A take-up reel 16 side is the same.
