Patent ID: 7684685

Claim:
An image stabilizer that stabilizes images by moving a correcting lens of a lens system in a first direction perpendicular to an optical axis of the lens system and in a second direction perpendicular to the optical axis of the lens system and to the first direction, the image stabilizer comprising: a driver positioned at one side of the correcting lens which moves the correcting lens in the first direction and in the second direction, the driver comprising: a first flat coil comprising first adjacent linear thrust-generating coil portions of different lengths that generate thrust for moving the correcting lens in the first direction; a second flat coil comprising second adjacent linear thrust-generating coil portions that generate thrust for moving the correcting lens in the second direction; magnets that apply magnetic force to the first coil and to the second coil; and a yoke supporting the magnets and having a protrusion positioned on a side of the shorter of the first thrust-generating portions and in a region where the longer of the first thrust-generating portions extends beyond the shorter of the thrust-generating portions, wherein the first coil and the second coil are positioned such that the first thrust-generating portions overlap the second thrust-generating portions at substantially a right angle, an electric current is made to flow in the same direction in the first thrust-generating portions and in the second thrust-generating portions, and the magnetic force is applied in common to the overlap.
