    摘要: A rotating-body driving device comprising: a rotating body; a driving source; a reduction gear that includes an output shaft and a gear rotating at a non-integer ratio of rotation period to a rotation period of the output shaft, and the reduction gear reducing rotation speed of the driving source; a pulse-signal generating unit; a pulse-count storage unit; a speed-fluctuation storage unit that stores therein a rotation speed fluctuation of the output shaft; and a driving-source control unit, wherein the driving-source control unit detects the speed fluctuation information associated with the accumulated number of pulse signals from the speed-fluctuation storage unit, and performs for the driving source a feedforward control to set off the rotation speed fluctuation.

    摘要: A rotator driving system for driving a rotator with a motor includes a dynamic vibration absorber attached to a rotary shaft of the rotator. The dynamic vibration absorber includes an inertia body, a viscosity-providing component to provide a viscosity, and a torsion spring unit to function as a torsion spring that includes a boss fixed to the rotary shaft. Multiple spokes extend radially outward from the boss. Multiple seats are provided at respective tips of the multiple spokes to fix the inertia body. The torsion spring unit is fixed by both the rotary shaft of the rotator and the boss fixed to the rotary shaft therebetween. The viscosity-providing component supports the inertia body via the multiple seats provided at the respective tips of the multiple spokes.
