LENS HOLDER DRIVING DEVICE INCLUDING DAMPER COMPOUND SUPPRESSING UNDESIRED RESONANCE
First Claim
1. A lens holder driving device comprising:
- a lens holder moving portion in which a lens holder moves in a direction of an optical axis and in first and second directions which are orthogonal to the optical axis and which are perpendicular to each other; and
a fixed member disposed apart from said lens holder moving portion in the direction of the optical axis,wherein said lens holder driving device comprises;
an elastic member mounted to said lens holder moving portion;
a plurality of suspension wires having first end portions fixed to said fixed member at outer regions thereof, said plurality of suspension wires extending along the optical axis and having second end portions fixed to said elastic member, said plurality of suspension wires swingably supporting said lens holder moving portion in the first direction and the second direction; and
at least one damper compound disposed so as to enclose at least one suspension wire among said plurality of suspension wires, said damper compound suppressing undesired resonance in said lens holder moving portion.

Abstract
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.
