<p>PURPOSE:To provide a stable running of the tape during the rewind-reproducing by regulating the tape in a manner that the tension post is located opposite the tape cassett about the extension line of the tangent that contacts the peripheries of the inclined post and the regulation post. CONSTITUTION:In the process of rewinding the tape 2 around a cylinder 5, a loading post 6 and a pinch roller 15 move as carrying the tape 2 off the tape cassett 1 from the position shown by the broken line to that shown by the full line. Along with this moving, the primary lever 17 moves toward the direction of arrow C. In association with it, a lever pin 18 fits in the primary cam part of the secondary lever 12. Following the form of the cam, the secondary lever 12 revolutes clockwise around the spindle 12a in the center. In association with the revolution of the secondary lever 12, the point abutting on the joint pin 14 formed on an tension arm 10 and the secondary cam part 13 is slipped off, and the tension arm 10 turns counterclockwise around an axis 10a. Abutting a stopper 15, the tension arm 10 stops.</p> |
