Dual lens camera
First Claim
1. A dual lens camera comprising a lens carrier with a shorter focal length lens and a longer focal length lens for alternatively positioning only one of said lenses at a picture-taking axis, is characterized in that:
- a single aperture for each one of said lenses is movable forward and rearward along the picture taking axis; and
said lens carrier is movable across the picture-taking axis to position said shorter focal length lens at the picture-taking axis when said aperture is moved rearward along the picture-taking axis and to position said longer focal length lens at the picture-taking axis when said aperture is moved forward along the picture-taking axis.

Abstract
A dual lens camera has a lens carrier with a shorter focal length lens and a longer focal length lens for alternatively positioning only one of the lenses at a picture-taking axis. A single aperture for each one of the lenses is movable forward and rearward along the picture taking axis. The lens carrier is movable forward and rearward along the picture-taking axis in unity with the aperture, and is movable relative to the aperture to position the shorter focal length lens at the picture-taking axis when the aperture is moved rearward along the picture-taking axis and to position the longer focal length lens at the picture-taking axis when the aperture is moved forward along the picture-taking axis.

10. A method in a dual lens camera of changing whichever one of a shorter focal length lens and a longer focal length lens is positioned at a picture-taking axis to the other lens, comprising the steps:
-
pivoting a selection lever coupled with a single aperture for each one of the shorter and longer focal length lenses to move the aperture forward and rearward along the picture taking axis; and
moving a single lens carrier for the shorter and longer focal length lenses forward and rearward along the picture-taking axis in unity with the aperture, and simultaneously moving the lens carrier relative to the aperture to position the shorter focal length lens at the picture-taking axis when the aperture is moved rearward along the picture-taking axis and to position the longer focal length lens at the picture-taking axis when the aperture is moved forward along the picture-taking axis.
