PURPOSE:To obtain a picture print of high quality by putting a filter between a light source and a film to correct the wavelength of the illumination light of the light source. CONSTITUTION:The light of a light source 1 is irradiated on a film 3 via a lens system containing condenser lenses 21 and 22, and the light transmitted through the film 3 is projected to a screen system or a print system via a projection lens 4. A filter 10 can be put between the light source 1 and the film 3, e.g., between lenses 21 and 22 in order to correct the wavelength of the light irradiated from the source 1. A reflecting plate 5 set at the back of the source 1. The filter 10 is set a position shown by a solid line in the figure in a reader state and then shifted to the position shown by a dotted line in a print mode respectively. Thus the filter 10 is put into an optical path. |
