Abstract
A shake correcting system includes an optical imaging system, an image sensor, a movable unit comprising a movable frame in which the image sensor is fixed and a rotation restricting element, a base movably supporting the movable unit in a predetermined plane substantially orthogonal to an optical axis of the optical imaging system, a drive mechanism driving the movable unit relative to the base in directions vertical and orthogonal to the optical axis, a blur correcting function to correct blurs in a subject image due to shakes of the shake correcting system, a rotation restricting mechanism preventing rotation of the movable frame around the optical axis with the rotation restricting element, and a slide mechanism allowing the movable unit to be freely movable in the predetermined plane, and comprising a magnet, a magnetic plate attracted to the magnet, a spherical element supported between the magnetic plate and the magnet.
