Abstract:
A drive is provided executing high-speed oscillatory motion. A voice coil motor in a pixel shifter includes a coil of a rectangular shape producing thrust along an axis, a flap fixing the coil, and flat springs giving to the flap an urging force against the thrust. An oscillation axis of the flap is parallel to the axis and located between another axis that is parallel and opposite to the axis and still another axis that is parallel to the axis and passes over a centroid of the coil. This reduces the value of the inertia per unit torque.
