Patent ID: 7142077

Claim:
A two-axis actuator comprising: a substrate; an anchor unit fixed on the substrate, the anchor unit comprising approximately rectangular sides, including first sides facing each other and extending in a first direction, the first sides having a plurality of corresponding discrete portions; first actuating parts disposed in regions adjacent to second sides of the anchor unit extending in a second direction orthogonal to the first direction, the first actuating parts moveable in the first direction; second actuating parts disposed a predetermined distance above the substrate and formed between the first actuating parts in a region adjacent to the first sides of the anchor unit extending in the first direction, the second actuating parts moveable in the second direction; a stage of a rectangular shape disposed on the second actuating parts so as to be movable in the second direction; a third actuating part separately disposed between the stage and the anchor unit, wherein the third actuating part is disposed on the first actuating parts as one body to move the stage in the first direction by a movement of the first actuating parts; first direction deformable springs disposed at inner faces of the anchor unit for enabling the first actuating parts to move in the first direction; and second deformable springs disposed at inner faces of the third actuating part for enabling the second actuating parts to move in the second direction.
