PROBLEM TO BE SOLVED: To expose photographic paper by simultaneously carrying several sheets of photographic paper by a carrying belt and to rationally control a light shielding diaphragm in the case of changing the size of the photographic paper. SOLUTION: The control form of a controller 50 is set so that the photographic paper P at an exposing position EP may be exposed by performing control that an interval between the light shielding diaphragms 15 is set to a set value based on the number of sheets in the case of carrying the several sheets of photographic paper P by the carrying belt 9, fogging may be prevented from occurring by covering the photographic paper P on the left side and the right side of the position EP, and the diaphragm 15 may not be actuated when the number of sheets of the photographic paper P is the same even in the case of changing the size of the photographic paper P.
