Abstract
A device, having a planetary gear and a single motor, in use for switching and transmitting a driving force of the motor to any one of station gears and for driving each station gear in both rotational directions. The operation of locking levers for preventing a planetary gear from revolving around a sun gear is controlled by a cam. The cam is actuated by a driving force of the motor. A spring frictionally connecting the cam and an output shaft of a speed reduction system is interposed therebetween, and a magnet is disposed so as to restrict the movement of the cam when the motor rotates. A sun gear is connected with the output shaft of the speed reduction system with a 'play' or gap in order that the rotation of the sun gear is reversed behind time corresponding to the play when the rotation of the motor is reversed, thus making it possible to start actuating the cam earlier than the sun gear for making sure that the locking levers are shifted.
