A rotary solenoid includes a rotating shaft on which a rotor is fixedly mounted, a pair of stators arranged on both sides of the rotor and a driving coil disposed around the stators. The opposed arrangement of the pair of stators allows to rotate the rotating shaft at high speed. When the rotary solenoid is combined with a one-way clutch, there is provided an apparatus for converting an oscillating rotary motion into an incremental and intermittent rotary motion, which may be advantageously applied to a system for advancing an ink ribbon in a printer and the like.
