<p>PURPOSE:To execute fast forwarding and rewinding at a high speed by providing the number of revolution detecting means of a winding side for detecting the number of resolution of a winding reel, the number of revolution means of a supply side for detecting the number of revolution of a supply reel, and a control unit for lowering separately a supply voltage to driving means of the supply side and the winding side. CONSTITUTION:At the time of rewinding, when it is detected by a number of revolution detecting means of a winding side that the number of revolution of a winding reel 28 has entered into a prescribed range, an applied voltage to a driving means of a supply reel 18 is lowered by one control unit 71. At the time of fast forwarding, when it is detected by a number of revolution detecting means of a supply side that the number of revolution of the supply reel 18 has entered into a prescribed range, an applied voltage to a driving device of the winding reel 28 is lowered by the other control unit 72. In such a way, a damage of a tape is prevented at the time of fast forwarding and rewinding, and also, fast forwarding and rewinding can be executed at a high speed.</p> |
