Abstract
An image-taking lens unit includes: a variable magnification optical system for forming an optical image of an object with a variable magnification; and an image sensor for converting the optical image into an electrical signal. The image-taking lens unit changes the shape thereof between a photographing state and a non-photographing state. The variable magnification optical system has a plurality of lens groups for performing magnification variation by changing intervals therebetween and a reflective surface for bending an optical axis. At least one of the plurality of lens groups is a movable group that moves during magnification variation. The reflective surface is kept in fixed position during magnification variation or focusing. In transition from the photographing state to the non-photographing state, at least the reflective surface moves so that at least part of the movable group is stored into a space left after the movement of the reflective surface.
