LENS DRIVING DEVICE
First Claim
1. A lens driving device comprising:
- a lens frame;
a supporting frame for supporting the lens frame elastically in the optical axial direction through a leaf spring;
a base supporting member for supporting elastically the lens frame, which is supported on the supporting frame, in a direction that is perpendicular to the optical axis, through a supporting wire; and
a driving portion for driving the lens frame in the optical axial direction and in one or both directions that are perpendicular to the optical axis, wherein;
the leaf spring comprises an elastic arm portion that is pulled to the outside by an attaching portion of the supporting frame, and a wire attaching portion that is connected to the elastic arm portion; and
the connecting position of the wire attaching portion and the elastic arm portion is disposed to the outside of a securing position for securing a tip end portion of the supporting wire to the wire attaching portion.

Abstract
Disclosed is a lens driving device includes: a lens frame; a support frame that elastically supports the lens frame in the optical-axis direction through plate springs; a base support member that elastically supports the lens frame supported by the support frame, in a direction intersecting the optical axis, through support wires; and a driving unit that drives the lens frame in one or both of the optical-axis direction and the direction intersecting the optical axis. The plate springs include elastic arm sections, respectively, which project outward of a portion at which the support frame is attached; and wire attaching sections which are connected to the elastic arm sections, respectively. A connecting position at which the wire attaching section and the elastic arm section are attached to each other is disposed outward of a fixing position where the leading end portion of a corresponding one of the support wires is fixed to the wire attaching section.
