Lens drive device

摘要

A lens drive device may include a first holding body, a second holding body, a fixed body which holds the second holding body, a first drive mechanism to drive the first holding body, a second drive mechanism to drive the second holding body, a third drive mechanism structured to drive the second holding body in a different direction than the second drive mechanism, an elastic member having a fixed part which is fixed to the second holding body and a deformable part, and plural wires in a substantially straight line shape with one end side fixed to the deformable part and the other end side fixed to the fixed body.

1. A lens drive device comprising:
a first holding body configured to hold a lens and movable in an optical axis direction of the lens;
a second holding body configured to hold the first holding body so that the first holding body is movable in the optical axis direction;a fixed body configured to hold the second holding body so that the second holding body is movable in a first direction and second direction, the first direction and the second direction being substantially mutually perpendicular and substantially perpendicular to the optical axis direction;a first drive mechanism which is structured to drive the first holding body in the optical axis direction;a second drive mechanism which is structured to drive the second holding body in the first direction;a third drive mechanism which is structured to drive the second holding body in the second direction;an elastic member having a fixed part which is fixed to the second holding body and a deformable part which is capable of being elastically deformed in the optical axis direction;plural wires in a substantially straight line shape each having a first end fixed to the deformable part and a second end fixed to the fixed body; anda connecting plate spring which connects the first holding body with the second holding bodywherein the second holding body is supported by the fixed body so as to be movable in a direction substantially perpendicular to the optical axis direction through the plural wires;wherein the plural wires are inclined with respect to the optical axis direction so that the first ends of the plural wires are widened with respect to the second ends of the plural wires when viewed in the first or second direction; wherein the deformable part is elastically deformed in the optical axis direction by a force smaller than a buckling load of the wire; wherein the elastic member is a plate spring which is disposed so that its thickness direction; is the optical axis direction; wherein the plate spring and the connecting plate spring are integrally formed with each other.
