<p>PURPOSE:To bring a pinch roller press contact onto a capstan and also to move quickly the pinch roller in the vicinity of the capstan by turning an arm, moving the pinch roller in the vicinity of the pinch roller and also stopping the pinch roller in the vicinity of the capstan and providing a means pressing the pinch roller to the capstan from the vicinity of the capstan succeedingly. CONSTITUTION:The pinch roller 7 is moved by turning a fitting arm 12. Thus, the pinch roller 7 is moved quickly from a position retarded largely from the capstan 8 in the vicinity. Further, the pinch roller 7 positioned in the vicinity of the capstan 8 is pressed into contact via a toggle mechanism 15 by the driving of a solenoid plunger 18. Thus, the pinch roller 8 is pressed to the capstan under a large pressure to obtain a smooth running of a magnetic tape 4. Since the pinch roller 7 is pressed to the capstan 8 only with the horizontal turning, the position shift of the magnetic tape is not caused.</p> |
