Patent ID: 7088018

Claim:
An electromagnetic drive type actuator comprising: a movable plate having a flat surface; a support positioned around the movable plate; an elastic member, which is elastically deformable, connecting the movable plate with the support, the elastic member supporting the movable plate so as to allow the movable plate to move in directions orthogonal to the flat surface of the movable plate; wirings, which carry currents, extending through the support, the movable plate, and the elastic member; and magnetic field generating means for generating a magnetic field in a space around the movable plate, the magnetic field having a direction parallel to the flat surface of the movable plate, so that the movable plate is moved in the directions orthogonal to the flat surface of the movable plate by a mutual effect between the currents flowing through the wirings and the magnetic field generated by the magnetic field generating means; wherein the elastic member comprises parts extending in two directions, which are not parallel to each other.
