On the other hand, it is conceivable to provide a neutral density filter on the light incident side of the line CCD 74 in order to diminish a portion where the amount of light incident on the line CCD 74 is large. In order to keep the size of the image to be made constant, the magnification of the lens unit 72 must be changed according to the size of the photographic film and the like. On the other hand, in the present embodiment, a dedicated film carrier is provided according to the size of the photographic film 22, so that it is possible to support photographic films of various sizes without changing the magnification of the lens unit 72. .

Further, in the present embodiment, the light source 6
The light emitted from the light source 4 is attenuated by the ND filters 30A and 30B, and the attenuated light is applied to the photographic film 22, but the invention is not limited to this. For example, the light emitted from the light source 64 may be applied to the photographic film 22, and the light transmitted through the photographic film 22 may be attenuated before entering the line CCD 74. That is, ND filters 30A and 30B for dimming light
May be provided on one of the emulsion side and the side opposite to the emulsion side of the photographic film 22, or may be provided on both sides.

In this embodiment, the line CCD 7
