Abstract:
1. An image stabilizer used in an optical instrument comprising: a base block fixed to the optical instrument; an inner frame for holding an optical element disposed on an optical axis of the optical instrument; an outer frame disposed outside the inner frame; a pair of first leaf springs disposed in parallel with each other and elastically deformable in a first direction in a plane orthogonal to the optical axis, each of the first leaf springs being fixed to the inner frame at an end and to the outer frame at the other end; a pair of second leaf springs disposed in parallel with each other and elastically deformable in a second direction transverse to the first direction in the plane orthogonal to the optical axis, each of the second leaf springs being fixed to the outer frame at an end and to the base block at the other end; an actuator for shifting the inner frame or the outer frame while bending the first leaf springs or the second leaf springs, so that the optical element is shifted to counteract a shake in the first direction or the second direction; and a flexible printed circuit disposed along at least one of the first leaf springs and at least one of the second leaf springs, for being bent together with the first leaf springs and the second leaf springs.
