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.

Abstract: The single-lens reflex camera of present invention features its shutter device. The shutter device includes a support plate having an opening through which an imaging medium is exposed to a light beam from a subject, a shutter blade for opening and closing the opening, and a shutter control part for driving opening and closing movement of the shutter blade, wherein the shutter control part is located behind the support plate along the optical axis of the subject light beam.

Abstract: In an electronic device having a movable member being capable of moving therein and an electric wire member disposed therein and deformed in association with the movement of the movable member, a movable guiding member being capable of moving independently of other members for guiding the electric wire member in association with the movement of the movable member is provided. Accordingly, deformation of the electric wire member in association with the movement of the movable member can be controlled by being guided by the movable guiding member. An example of the electronic device to which the present invention is applied is a lens barrel.

Abstract: A beam splitter splits a light beam having passed through an image pick-up device into a plurality of split light beams. An image pick-up device converts one of the split light beams emitted from the beam splitter to an electric signal. An optical viewfinder uses another one of the split light beams emitted from the beam splitter for visually recognizing an image. The eyepiece of the optical viewfinder is disposed on an upper part of the rear surface of the camera body adjacent the left end thereof.
