Title:
LENS DRIVING UNIT AND CAMERA MODULE COMPRISING THE SAME
Document Type and Number:
Japanese Patent JP2010097216
Kind Code:
A
Abstract:
To provide a lens driving unit that generates a precise linear motion in a spatially limited structure by using a bending vibration piezoelectric motor having a new structure; and to provide a camera module comprising the lens driving unit.
The lens driving unit 100 includes: a lens carrier 110 supporting a lens 111 therein; an axial guide unit 112 provided to be exposed at least partially to the side surface of the lens carrier and extending in a direction substantially perpendicular to the lens; and a piezoelectric driving unit 120 having a piezoelectric element arranged in contact with the axial guide part and moving the lens carrier in a direction in which the axial guide part extends by a bending motion of the piezoelectric element.
