Abstract: PURPOSE: To prevent tape sag, to keep tape tension and to remove a noise by rotating a reel disk by a prescribed angle in the direction of winding the tape. CONSTITUTION: An engagement piece 11e projectingly provided on a guide hole 11b is transferred in the direction of an arrow (b) by transferring a main slide device 11, and an operation lever 14 is turned in the direction of the arrow (d) by force of an elastic member 13. A tooth-like projection 14a is engaged with a drive gear 16 by the turning of the gear 16, and the gear 16 is rotated in the direction of the arrow (e). Thus, a release spring loaded on the boss outside diameter of the gear 16 is wound, and torque is generated, and the rotational force of the gear 16 is transmitted to a transmission gear 17 through the release spring. Then, the gear 17 and a supply reel disk engaged with a gear part 12b are rotated by a prescribed angle. The lever 14 stops to turn by a stopper 12c of a boss 12a. Thus, the sagged tape is rewound, and the occurrence of the sag is prevented.
