<p>PURPOSE:To prevent the application of an excess force to a driving motor by using a double gear and a torsion spring to branch driving force, moreover burdening the reaction force of the torsion spring on a fast winding post drawing spring. CONSTITUTION:Through first and second link gears 11 and 12 linked to a fast winding post driving plate 9, a fast winding post drawing gear 13 on the right side turns in the clockwise direction which is a releasing direction, a fast winding post block 15 on the right side turns to the fast winding direction by the energizing force of a fast winding post drawing spring 16 and a fast winding post 14 on the right side moves to the fast forwarding position. Moreover a fast winding gear 19 on the left side moves in a counterclockwise direction and a fast winding post block 21 on the left side turns to the fast winding position by the energizing force of a spring 22, so that a fast winding post 20 on the left side moves to the fast winding position. The action from the driving gear to the fast winding post drawing gears 13 and 19 is executed almost at the same time and the energizing force of the fast winding post drawing springs 16 and 22 acts to the rotating direction of the driving gear so as to load the reaction force of the torsion spring with the aid of the energizing force of the springs 16 and 22.</p> |
