Abstract
PURPOSE: To simplify the constitution of a take-up apparatus for a tape and facilitate the loading thereof by controlling the reel torque according to the angular velocity of the reel when the tape travel speed is constant while according to the signal obtained by multiplying the angular velocity and the tension together in case of a transitional travel.
CONSTITUTION: When the speed of a tape 1 changes transitionally, the tape tension changes, causing a tape tension detecting post 9 to fluctuate, so that the signal of a magnetism-sensitive element 11 changes. Through a high-pass filter (not shown), said signal is multiplied by the detection signal of a roll diameter detecting unit comprising a light-emitting element 14, a light-receiving element 15, an optical encoder 13 and an apparatus which is not shown. Then, said multiplication signal is added to the roll diameter detecting signal in order to control a reel driving unit 3. When the speed of the tape 1 is constant, no output is generated from the magnetism-sensitive element 11, so that the driving unit 3 is controlled according to the speed of the reel 2. Thereby, the tape travel route is simplified, and the loading of the tape 1 is facilitated.
