<p>PURPOSE:To prevent a phase shift between a mode ring and a tape guide driving means from generating, to simplify a mechanism, and to reduce cost, by driving the tape guide driving means by the turning of the mode ring only for a prescribed interval. CONSTITUTION:In a state possible to draw out a tape from a cassette, the rotation of a link gear 5 is suppressed by the abutting of stoppers 5-e and 5-d with the end face 4-d of a mode ring 4, then the link gear 5 being positioned. Next when the ring 4 is started to rotate, and the stopper 5-e is engaged with the ring 4, an interference between the tip shape of the stopper and the engaging part of the ring 4 is eliminated by a recessed groove 4-f having a wide width. And after a loading operation, a stopper 5-c is regulated by the end face 4-d of the ring 4, thereby a rotation being held, and it is possible to perform a mode operation keeping the loading operation. Thus, since it is possible to perform the mode operation keeping the drive of the gear 5, etc., by the turning of the ring 4 only for the prescribed interval, and holding a state, the phase shift between the ring 4 and the gear 5, etc., can be prevented, and the mechanism can be simplified.</p> |
