Abstract:
1. An actuator which tilts and drives an object to be driven around an axis of rotation, comprising: a pair of supporting beams arranged to support the object to be driven from both sides thereof in a direction parallel to the axis of rotation; a pair of movable frames arranged to sandwich the object to be driven and the pair of supporting beams from both sides in a direction perpendicular to the axis of rotation; a plurality of beams arranged to sandwich the pair of movable frames from both sides thereof in the direction perpendicular to the axis of rotation and support the object to be driven; a resonant drive source arranged to apply bending vibration to the pair of movable frames and drive the object to be driven around the axis of rotation when a resonant drive operation is performed; and a non-resonant drive source arranged to apply bending vibration to the plurality of beams and tilt and drive the object to be driven around a second axis of rotation perpendicular to the axis of rotation when a non-resonant drive operation is performed.
