Abstract
A driving device for a moving body comprises a drive shaft normally rotated in one direction by a drive source, a follower shaft in engagement with the drive shaft to transmit the drive to the moving body, one-way connecting means loosely mounted on the drive shaft to connect and disconnect the drive of the drive shaft to the follower shaft, and accumulator means for accumulating the returning force of the moving body by utilizing the movement of the moving body resulting from the normal rotation of the follower shaft. The follower shaft may be reversed in rotation by the accumulator means upon disconnection of the one-way connecting means and the speed of the reverse rotation of the follower shaft is controlled by operation of the one-way connecting means so as not to exceed the driving speed of the drive shaft.
