Abstract
A camera consists of a lens barrel unit, a spool chamber unit, a Patrone chamber unit, and a substantially plate-like linking member. The linking member has a photographic aperture, and guide rails for restricting the position of a film relative to the photographic aperture. The linking member links the spool chamber unit and Patrone chamber unit. A picture size switching mechanism realizing a picture size switching function for partly blocking the photographic aperture is mounted on the linking member. The camera further includes a viewfinder picture size switching mechanism for switching viewfinder picture sizes, and a switching control unit for controlling the photographic picture size switching mechanism and viewfinder picture size switching mechanism so that a photographic picture zone and viewfinder picture zone will be set to the same picture size. After the viewfinder picture zone is switched from a large picture size to a small picture size, the photographic picture zone is wider than a field of view defined as the viewfinder picture zone.
