Abstract

A driving mechanism configured to turn a plate member with respect to a frame member around a predetermined turning axis includes a pair of supporting members supporting the plate member, a pair of actuators provided on both sides with respect to the turning axis and on the same surface side of the plate member. Each of the actuators includes a fixed electrode unit fixed to the frame member and a movable electrode unit fixed to the plate member. The fixed electrode unit includes a substrate, a pair of fixed comb electrodes provided on both surface sides of the substrate. The movable electrode unit includes a pair of movable comb electrodes, each of which engages with the corresponding fixed comb electrode with a gap therebetween. Both pairs of the fixed comb electrode and the corresponding movable comb electrode are configured such that a voltage can be applied therebetween independently.
