Abstract

There is providing a lens barrel assembly including a base, a movable module movable along a linear path between a position close to the base and an extended position from the base, and a flexible printed circuit board including a first connection part, a bent part, and a second connection part. An end of the first connection part is connected to the movable module. The bent part is bent from the other end of the first connection part. An end of the second connection part is connected to the base and the other end of the second connection part is connected to the bent part. When the movable module is at a position close to the base, the first and second connection parts are close, and when the movable module is at the extended position, the first and second connection parts spread apart from the bent part.

Description

[0001] This application claims the priority benefit of Korean Patent Application No. 10-2011-0052392 filed with the Korean Intellectual Property Office on May 31, 2011, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a lens barrel assembly, and more particularly, to a lens barrel assembly provided with a flexible printed circuit board to reduce its size, space, and number of parts. Background technique [0003] A photographing device such as a digital camera may include a lens barrel member. Such a lens barrel member may be detachably attached to the photographing apparatus or may be permanently attached to the main body of the photographing apparatus provided with the image pickup device. The lens barrel assembly may include optical systems for focusing, zooming, and light amount adjustment. [0004] A main circuit board may be included in the lens barrel assembly to move the optical system, adju...
