To easily judge an exposure image plane in the case of shortening the short side or the long side of the exposure image plane reflected according to an exposure range decided by an exposure aperture frame.

Signal parts 26a and 26b and signal parts 26c and 26d are respectively formed on the upper and lower sides of the aperture edges of the exposure aperture frame of H size and at positions corresponding to the ends of an L size printing range in performing L size printing from the exposure image plane of H size. When photographing is executed, a mark expressing the end of the L size printing range is reflected with the exposure image plane of H size by the signal parts 26a and 26b and the signal parts 26c and 26d, so that the size of the exposure image plane is recognized.
