PURPOSE:To smoothly execute contact and separation of a gear and transfer of power by simple constitution, by providing idler gears for reproducing and quick traversing on a turning plate, meshing them with a gear of a prime mover side at all times, and executing reproducing and quick traversing by changing the turning direction. CONSTITUTION:A turning plate 40 is pivotally supported by a shaft 9 so as to be freely turnable, and idler gears 27, 29 for reproducing and quick traversing are provided so as to be freely rotatable. The gears 27, 29 are always meshed with an intermediate gear of the lower part of a pulley driven by a motor, but in case of a stop state, they are not meshed with a reproducing gear 28. When a reproducing plate 4 is pushed in the direction as indicated with an arrow, the plate 40 is turned clockwise, and the gear is meshed with 28b of the reproducing gear and becomes a reproducing state. When a quick traversing control panel 5 is pushed in the direction as indicated with an arrow, the plate 40 is turned counterclockwise in reverse, and the gear 29 is meshed with 28a of the reproducing gear and becomes quick traversing. Therefore, contact and separation of the gear and transfer of power can be executed smoothly by simple constitution. |
