Patent ID: 6995495

Claim:
An actuator comprising: a stage having a first direction and a second direction perpendicular to the first direction and seesawing around a third direction perpendicular to the first direction and the second direction with respect to a rotation center axis placed along the first direction; a first support portion supporting a seesaw motion of the stage; a base facing the stage under the stage at a predetermined interval and supported by the first support portion; a stage driving portion having a plurality of first driving comb electrodes and a plurality of first stationary comb electrodes corresponding to the first driving comb electrodes which are respectively formed on a lower surface of each of the stages and an upper surface of the base facing the stages; a second support portion supporting the first support portion so that the first support portion seesaws with respect to a rotation center axis placed along the second direction; and a first support portion driving portion having a second driving comb electrode provided at the first support portion and a second stationary comb electrode fixedly positioned to correspond to the second driving comb electrode to generate a seesaw motion of the first support portion.
