<p>PURPOSE:To make selective drive of a reel turntable with simple and small- sized constitution, by driving the reel turntable selectively according to the direction of revolution of a motor possible for forward and reverse operation through the adoption of a unidirectional rotating clutch. CONSTITUTION:Between a winding reel gear 35 and a follower rotating wheel 36, a clutch which can be delivered to the follower rotating wheel 36 only for the clockwise rotation of a winding reel gear 35 is provided and a supply reel turntable device is provided with a clutch function which can deliver only the counterclockwise revolution opposite to the winding reel turntable device. Thus, when a motor 28 is driven clockwise, a winding reel shaft 37 only rotates clockwise and no supply reel shaft 137 rotates. When the motor 28 is driven counterclockwise, the operation is entirely opposite. Thus, the reel turntable device can be selectively driven by only changing the direction of revolution of the motor.</p> |
