Title:
LENS MOVEMENT MECHANISM, IMAGING UNIT, AND ELECTRONIC EQUIPMENT
Document Type and Number:
Japanese Patent JP3912365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make the optical axis of a lens to be able to be aligned to other lenses and an imaging device, etc., even when the lens is moved to the direction of its optical axis.
SOLUTION: An imaging unit 1 is equipped with a lens unit 2 consisting of a plurality of single lenses, a solid-state image pickup device 3 on which the imaging of an image is formed by the lens unit 2 and a lens movement mechanism 10 for moving the lens unit 2 along the optical axis. The lens movement mechanism 10 is equipped with a guide rail 4 which supports the lens unit 2 so that the unit 2 approaches and separates from the solid-state image pickup device 3, a spring 5 which performs pressurization so as to bring the the unit 2 close to the device 3 and a lever member 6 which is abutted on the unit 2 so as to resist against the pressing force of the spring 5.
