Abstract
A lens housing has an immobilized frame supporting a drive ring, in which a rotating frame supported therein and a moving frame having a helicoid ring are supported so as to be rotationally extendable and/or retractable. When the helicoid ring is rotationally driven, the rotating frame and the moving frame can be integrally extended from a collapsed-barrel position to an image-capturing position. When the rotating frame in the image-capturing position is rotationally driven by the drive ring, the individual frames can be extended to zoom positions. The lens housing allows compactness and miniaturization to be implemented.
