ABSTRACT:
An actuator, and a lens unit and a camera incorporating the actuator. The actuator includes fixed and movable members, a support supporting the movable member to permit its movement in a plane parallel with the fixed member, at least three actuating coils attached to one of the fixed and movable members, actuating magnets attached to the other of the fixed and movable members in positions corresponding to the actuating coils to apply magnetic force thereto to affect each other when current flows therein, a position sensor detecting a relative position of the movable and fixed members, and a controller producing a coil position command signal based on a command signal to instruct where the movable member is to be moved and controlling the drive current to flow in each of the actuating coils in response to the coil position command signal and the position data detected by the position sensor.
