摘要 PURPOSE:To miniaturize the shape of a main frame body, by providing a split mask made of a flexible material having various photographic holes differing in size so that it can reciprocate at right angles to the moving direction of a film holder. CONSTITUTION:Inside of frame body 21, guide rails 22 are fitted lengthwise opposing to each other and film holder 24 can reciprocate lengthwise between stand-by position I and photographic position II. At photographic position II, split mask 26 made of a flexible material which can move at right angles to the lengthwise direction is arranged. Split mask 26 has different photographic holes for entire-surface photographing, two-division photographing, longitudinal-division photographing, four-division photographing, etc., and, for example, film holder 24 containing film 23 is moved as shown by arrow E until photographic hole 27D of split mask 26 for four-division photographing agree with the photographic point of film 23, so that photographing can be performed at two parts of film 23.
