Abstract
A drive conversion mechanism includes a rotatably mounted output shaft, a pair of output gears mounted on the output shaft so as to rotate independent of one another and relative to the output shaft and being displaced from each other axially along the output shaft, and a pair of one-way clutches arranged about the output shaft. Each clutch is connected to one of the output gears and extends about the output shaft in respective orientations that are the reverse of each other such that the one-way clutches can only drivingly engage the output shaft at alternate times, and thus not at the same time, so as to cause the output shaft to rotate in a same single direction as the output gears are driven in opposite directions relative to each other by an input train of constantly meshed input drive and idler gears.
