<p>PROBLEM TO BE SOLVED: To provide a pinch rollerless tape running-driving device off a simple and inexpensive configuration. SOLUTION: In the pinch rollerless tape running-driving device using a friction drive capstan 12 for running a tape 1 constantly between a supply reel 13 and a take-up reel 14, tension detection pales 18b and 18c where the tape 1 is wound at a specific angle at one end of a nearly Y-shaped tension arm 18 that can be rotated freely and at the same time a magnet piece 18d is provided at the other end in opposition a Hall sensor 19 that is fixed to a chassis 20, and the rotary angle of the tension arm 18 is detected by the output of the Hall sensor 19, thus adjusting the drive torque of a reel motor 15.</p> |
