<p>PURPOSE:To smooth the turning action of a cassette holder by providing first gears meshed with the respective synchronizing gears of a coupling shaft on respective turning arms and providing second gears meshed with both first gears through the synchronizing gears on a cover body. CONSTITUTION:The cassette holder 40 is lowered by adding depressing force on the cover body 58 in a closing direction shown by an arrow A. At this time, the synchronizing gear 66 meshed with the second gear 63 is turned in a direction shown by an arrow D by following the closing action of the cover body 58. Since a turning lever 54 is turned in a direction shown by an arrow C by resisting to the repulsive force of a spring 68 at the same time, the holder 40 is turned in a direction shown by an arrow B and the cover body 58 is turned in the closing direction. In the case that a cassette 20 is taken out to the outside, the lever 54 is turned in a direction opposite to the direction shown by the arrow C by the repulsive force of the spring 68 and the synchronizing gear 66 meshed with the gear 50 is turned in the direction opposite to the direction shown by the arrow D at the same time because a projection 41 is turned in the direction opposite to the direction shown by the arrow B. As the result, the cover body 58 is turned in an opening direction. Thus, the cassette 20 is smoothly loaded and unloaded.</p> |
