<p>PURPOSE:To reduce the load applied to a solenoid by using two solenoids to switch the revolutions of a motor in terms of mechanism for FF and REW actions, releasing the start of a play when both solenoids are actuated simultaneously and advancing a head van to start a play mode. CONSTITUTION:Both FF and REW solenoids 1 and 2 are actuated simultaneously, and an FF action part 1a and a REW action part 2a are moved to the left side. Therefore an FF/REW oscillating arm 3 is moved in parallel to the left from a stop mode, and rotary shaft parts 3a and 5c coupled to a play lock arm 5 are also moved to the left. Then the arm 5 is turned counterclockwise to release a hook state between a stop lock part 5a and a lock part 8f which are hooked in a stop mode. A play gear 8 receives the revolving power of a play arm 13 produced by a play arm spring 15 at a play arm contact part 8b in a stop mode. Thus the clockwise revolutions are obtained and therefore a head van advancing gear part 8c engages a flywheel gear 12. These gears have a contact with a part 17 to be actuated for REW. Thus an FF/REW selection slider 17 is slided downward.</p> |
