<p>PURPOSE:To simplify and miniaturize a mechanism by switching a program based on the forward and backward rotation of a motor. CONSTITUTION:When a head plate 3 is moved to a play mode position, the tip roller of a lever part of a lever 19 is moved to an aperture part with narrow width at the guide aperture part of a change plate 2. When the motor is switched from the forward rotation to the backward rotation or vice versa, an intermediate gear 8 is engaged with an intermittent gear 4 by the turning of an intermediate gear moving lever, and the rotation of a driving gear 10 is transmitted to the gear 4 via the gear 8. In such a way, the plate 2 is moved in one direction, and the lever 19 is rocked, and a pinch roller 15 on one side is provided oppositely to a capstan, and is separated from the pinch roller 15 on the other side, thereby, program change can be performed.</p> |
