Abstract
A fixed making frame for blocking the peripheral light is disposed between a taking lens aperture and an exposure frame of a film surface. The effective diameter of the taking lens aperture is variable so as to make an angular field of a photogtaphing light which extends from the taking lens aperture to an exposure area. The angular filed is smaller under a larger effective diameter than under a smaller effective diameter. A predetermined width of a periphery of the exposure area defines a non-print area, and the fixed making frame is disposed at a side adjacent to the taking lens aperture with respect to an intersection of the peripheral light which extends between an inner periphery of the non-print area and the lens aperture under a larger effective diameter of the taking lens, and a peripheral exposure light which extends the lens aperture and an outer periphery of the exposure area, under a smaller effective diameter of the taking lens aperture. The making frame is configured to block the photographing light outside the peripheral light which extends between the inner periphery of the non-print area and the taking lens aperture upon increased effective diameter of the taking lens.
