Abstract
Official abstract text for this publication.
A lens holder driving device includes a lens holder moving portion, a fixed member, suspension wires, and a damper compound. In the lens holder moving portion, a lens holder moves in an optical axis and in first and second directions which are orthogonal to the optical axis and which are perpendicular to each other. The fixed member is disposed apart from the lens holder moving portion in the direction of the optical axis. The suspension wires have first end portions fixed to the fixed member at outer regions thereof, extending along the optical axis, having second end portions fixed to an elastic member mounted to the lens holder moving portion, and swingably supporting the lens holder moving portion in the first direction and the second direction. The damper compound is disposed so as to enclose at least one suspension wire and suppresses undesired resonance in the lens holder moving portion.
First claim
