Abstract

Official abstract text for this publication.

A lens-driving device includes a lens frame; a base member; a support that supports the lens frame such that the lens frame can move, relative to the base member, along the optical axis; a driving means that drives the lens frame along the optical axis; and a focus control unit that controls the driving means so as to move the lens frame to a focus position. The support has an elastic support member that supports the lens frame in a suspended manner in an elastic equilibrium position when the driving means is powered off. To set a focus baseline, the focus control unit controls the driving means so as to make the lens frame abut against a mechanical focus baseline position.

First claim

Opening claim text (preview).

1 . A lens driving device comprising: a lens frame; a base member; a support supporting the lens frame movably, in the optical axial direction, relative to the base member; a driver driving the lens frame in the optical axial direction; and a focus controller controlling the driver so as to adjust the lens frame to a focus position, wherein the support comprises an elastic support supporting the lens frame in a suspended state in an elastic equilibrium position when the driver does no…
