ABSTRACT:
A loading mechanism for a magnetic recording/playback apparatus provides a positioning mechanism which can reliably and fixedly position a loading boat with a quite simple structure when completing an operation of withdrawing a magnetic tape. The invention also provides a loading post driving and pressing device which can eliminate the need of using a two-staged gear fitted with a spring, position two loading posts under pressing by one urging device, and realize reduction of the size, weight and thickness. The invention further provides a loading post driving device in which a gear serving as a prime mover part has the two-stages structure to realize reduction of the size, weight and height, and driving force can be directly transmitted from the gear serving as a prime mover part to a large loading gear by using no geneva gear.
