Abstract
An image stabilizer has a base block, a CCD holder, an intermediate member, a rectangular frame-shaped first sheet metal member, a rectangular frame-shaped second sheet metal member, and voice coil motors (VCMs). The first sheet metal member has a pair of mutually-parallel horizontal leaf springs that is formed by bending upper and lower sides of the first sheet metal member. The second sheet metal member has a pair of mutually-parallel vertical leaf springs that is formed by bending right and left sides of the second sheet metal member. The horizontal leaf springs are flexible along a Y-axis, and the vertical leaf springs are flexible along an X-axis in a plane orthogonal to an optical axis. The VCMs shift a CCD through the CCD holder, while bending the horizontal or vertical leaf springs, to counteract a camera shake in an X-axis or Y-axis direction.
