发明名称 Camera capable of varying size of image plane
摘要 In a camera of the kind arranged to obtain an object image through a photo-taking lens at an arbitrary image plane size on a photosensitive surface by using an image plane size varying member, either the nearest shootable distance of the photo-taking lens is arranged to become shorter than the normally nearest shootable distance or the magnification varying range of the power varying part of the photo-taking lens is arranged to be expanded on the wide-angle side, as the diagonal length of the image plane size becomes shorter.
