Abstract
A camera according to the present invention includes a picture-taking lens unit including a picture-taking optical system having a bending optical system which optically bends incident light and an optical finder unit including a finder optical system having a bending optical system which optically bends incident light. A pre-bending optical system and a post-bending optical system in the bending optical system of the optical finder unit are arranged adjacent to a pre-bending optical system and a post-bending optical system in the bending optical system of the picture-taking lens unit, respectively. The body of the camera is therefore decreased in size.
Claims7
A picture-taking lens unit comprising:
- a lens barrel having a light-incident end;
- a picture-taking lens group which is provided so as to form an image of an object based on light incident from the light-incident end of the lens barrel;
- an image pickup device provided in the lens barrel to photoelectrically convert the image of the object formed by the picture-taking lens group;
- an optical member arranged along an optical axis of the picture-taking lens group and ahead of a light-receiving surface of the image pickup device;
- a lens holding frame which holds a specific lens of the picture-taking lens group, the lens holding frame being provided movably along the optical axis the picture-taking lens group;
- an actuator mounted on the lens holding frame, which controls a movement of the lens holding frame;
- and
- a band-shaped flexible printed board which is bent in a thickness direction and provided to supply power to a driving system including the actuator, and
- wherein a first space which houses the actuator is formed between an inner surface of the lens barrel and one outer surface of the optical member, and
- a second space which houses a portion curved by bending the flexible printed board is formed between the inner surface of the lens barrel and the other outer surface of the optical member.
