<p>PURPOSE:To make the tape running stable by providing a winding running guide means running a tape after passing a press contact means pressing a fixed member implanted while facing a tape running path between a supply level base and a head device at recording/reproduction via the tape by winding the tape with a prescribed angle. CONSTITUTION:The tape 9 drivne by a capstan 14 and a pinch roller 15 at recording/reproduction and coming out of a supply reel base (not shown) has a very small tension T0 by a load in a tape cassette even when the load torque of the supply reel base is zero. After the brake force is applied to the tape 9 by the press contact force, the tape is wound on a fixed guide roller 10 and the friction due to the winding is applied to form a tension T1 and then the tape is wound on a guide drum 3. The tape 9 is wound by the guide roller 10 at a winding angle theta.</p> |
