<p>PURPOSE:To smoothen the take-up operation by making a take-up gear having a gear to be engaged with a reel gear of a take-up reel freely movable in the thrust direction and providing a spring for energizing the take-up gear in the direction of engaging the take-up gear with the reel gear. CONSTITUTION:Driving power is transmitted via a limit gear 32a connected to a driving source, a rotating speed adjusting mechanism 32 consisting of a limit gear 32b connected to the take-up gear 41 and a torque limiter 32c provided in between and a gear 41 to the take-up reel 26. Under this constitution, the gear 41 is arranged to be movable in the thrust direction, and a coil spring 43 is provided for energizing the gear 41 in the direction of engaging with the reel 26. Then, when misengagement takes place between the reel gear 26a and a gear 41a, the gear 41 is pushed down, and a driving gear 41b is engaged with a gear 32a, so that the driving power can directly be transmitted to the gear 41. On the other hand, the gear 41 is rotated via the gear 32a, and is hence moved in the thrust direction by the spring 43 to engage with the gear 26a.</p> |
