ABSTRACT:
An electromagnetically controlled spring clutch mechanism for transmitting the rotating forces of an input rotating element adapted to rotate in a predetermined direction and in a direction opposite thereto to an output rotating element. According to one aspect, a first spring clutch mechanism and a second spring clutch mechanism are interposed between the input rotating element and the output rotating element, and the rotating force of the input rotating element in the predetermined direction is transmitted to the output rotating element by the contraction of a coil spring in the first spring clutch mechanism and the rotating force of the input rotating element in the opposite direction is transmitted to the output rotating element by the contraction of a coil spring in the second spring clutch mechanism. According to a second aspect, an inside transmission and an outside transmission are disposed between the input rotating element and the output rotating element; and the rotating force of the input rotating element in the predetermined direction is transmitted to the output rotating element via the inside transmission by the contraction of the coil spring, and the rotating force of the input rotating element in the opposite direction is transmitted to the output rotating element via the outside transmission by the expansion of the coil spring. According to a third aspect, a brake is disposed in relation to the output rotating element.
