ABSTRACT:
A photographic printer has a main exposure section which successively prints, onto a photographic printing paper, images of a plurality of image frames recorded on a developed photographic film; and a secondary exposure section for forming, on a sheet-shaped photographic printing paper, an index print in which the images recorded on the plurality of image frames are arranged lengthwise and breadthwise. The photographic printer includes, as a light source for exposure of the index print, a high luminance reflecting type LED which emits parallel light of a blue color component of light, a high luminance reflecting type LED which emits parallel light of a red color component of light, and a high luminance reflecting type LED which emits parallel light of a green color component of light. The photographic printer also includes a liquid crystal panel on which light from the high luminance reflecting type LEDs is incident, and which exposes the photographic printing paper. Accordingly, there is no need for a lens to make parallel the light from the high luminance reflecting type LEDs.
