Patent ID: 8049782

Claim:
An image blur correction device comprising: a fixed member; a movable member to which an imaging element is affixed; support means supporting the movable member relative to the fixed member such that the movable member can move translationally and rotationally within a plane parallel to the light receiving surface of the imaging element; at least three drive coils disposed on either the fixed member or the movable member; at least three position sensors disposed on the member among the fixed member and the movable member to which the drive coils are attached; at least three drive magnets respectively attached to the other of the fixed member or movable member at positions opposing each of the drive coils, so as to receive a drive force from the magnetic field generated by each of the drive coils; detection means for detecting blurring of an optical axis of light incident on the light receiving surface of the imaging element; and a control means for controlling the blurring of an image formed on the imaging element by sourcing current to each drive coil to move the movable member such that it is moved translationally, without rotational movement, in the X and Y directions, based on the optical axis blurring detected by the detection means, and based on the detected position of the movable member relative to the fixed member as detected by the position sensor; wherein three of the drive coils are disposed on an approximately straight line, and two of the drive magnets opposed thereto are disposed to receive a drive force in a direction of a first axis by a magnetic field generated by the drive coils, while the other drive magnet is disposed to receive a drive force in a direction of a second axis approximately perpendicular to the first axis by a magnetic field generated by the drive coil opposed thereto.
