ABSTRACT:
A light shielding member is composed of plural light shielding plates which increase and decrease an opening area by shielding an exposure opening at least partially, and at least two light shielding plates overlap each other to move from the exposure opening. The film is positioned in such a way that the film is transported in the same direction (feeding direction) when the normal size is switched to the panoramic size and vice versa. Even if the number of residual frames in the panoramic size is 0, the photography in the normal size is allowed when the photography is possible in the normal size. A display shows that the photography can be performed in the normal size, or the panoramic size is automatically switched to the normal size.
