PROBLEM TO BE SOLVED: To prevent the flatness of an exposure surface at the time of setting a film unit at an exposure aperture from being deteriorated due to the inclination of the film unit caused by long-term preservation in a film pack. SOLUTION: Plural film units 14 are housed in the film pack 10. The film unit 14 is pressed toward the exposure aperture 18 from a non-exposure surface side by a pressing means 24. Nearly circular-arc-shaped straightening ribs 25a for straightening the inclination of the film unit 14 caused by the pressing means 24 are respectively formed on the internal walls of two sides parallel with the ejection direction of the film unit 14 out of four constituting sides in the aperture 18. When the film unit 14 whose long side dimension is 85.6 mm is set in the aperture 18 whose dimension is 62×46 mm so that its longitudinal direction is aligned with the long side of the aperture 18 the flatness of the exposure surface of the film unit 14 is kept within±1 mm by the pressing means 24 and the rib 25a.
