Patent ID: 8264549

Claim:
An image stabilizer used in an optical instrument, comprising: a base block fixed to the optical instrument; an optical element holder for holding an optical element disposed on an optical axis of the optical instrument; an intermediate member disposed outside the optical element holder; a rectangular frame-shaped first sheet metal member fixed to the optical element holder and the intermediate member, for having a pair of first leaf springs that is formed by bending opposed two sides of the first sheet metal member in parallel with the optical axis and in parallel with each other, the pair of first leaf springs being elastically deformable in a first direction in a plane orthogonal to the optical axis; a rectangular frame-shaped second sheet metal member fixed to the intermediate member and the base block, for having a pair of second leaf springs that is formed by bending opposed two sides of the second sheet metal member in parallel with the optical axis and in parallel with each other, the pair of second leaf springs being elastically deformable in a second direction transverse to the first direction in the plane orthogonal to the optical axis; and an actuator for shifting the optical element through the optical element holder, while bending the first leaf springs or the second leaf springs, to counteract a shake in the first direction or the second direction, wherein the first sheet metal member, the second sheet metal member, and the intermediate member are integrally formed into an integrated sheet metal member by bending a single sheet of metal.
