Patent ID: 7420755

Claim:
A lens driving device for moving lenses to perform zooming and automatic focusing comprising: a first lens disposed movable during zooming and automatic focusing; a second lens disposed movable during zooming independently from the first lens; a lens movement guide member having a first guide part for guiding the movement of the first lens so that the first lens is moved during zooming and finely moved from a zoom position with respect to the second lens during automatic focusing, and a second guide part for guiding the movement of the second lens so that the second lens is moved during zooming and remains stationary on an optical axis during automatic focusing, wherein the lens movement guide member is rotated to move the first and second lenses; and an actuator providing driving power necessary to move the first and second lenses during zooming and automatic focusing; whereby both the first and second lenses are moved during zooming and subsequently, only the first lens is finely moved during automatic focusing so that zooming and automatic focusing is performed by the single actuator.
