<p>PURPOSE:To drive loading posts by a gear mechanism which consists of a small number of gears and to securely position the loading posts by driving one ring gear in one direction and driving the other gear through a pendulum gear and an intermediate gear. CONSTITUTION:A loading gear 34 drives one ring gear 39 and then drives the other ring gear 38 as well through the pendulum gear 43 and intermediate gear 42. After a loading post associated with the other ring gear 38 is stopped by a stopper first, the pendulum gear 43 swings through a swing plate 45 and a loading post associated with one ring gear 39 by the loading gear 34 is stopped by a stopper, thereby securing the positions of the supply and take-up side loading posts after loading completion. Consequently, only one ring gear 39 can be driven by the simple gear mechanism which is driven by the loading gear 34 and the two loading posts can be positioned at the same time.</p> |
