ABSTRACT:
An image reading device, in which two LED chip groups, light emission thereof being separately controlled, are disposed along a direction perpendicular to a conveyance direction of a photographic film. Acrylic blocks for guiding light to a vicinity of the photographic film, a lens unit for focusing light transmitted through the frame image, and a three-line CCD for receiving and conducting photoelectric conversion of the transmitted light are respectively disposed at positions corresponding to the LED chip groups. Hence, by simultaneously conveying photographic films, each having a width corresponding to the width of each LED chip group, and separately irradiating each of the photographic films from one LED chip group, frame images of each film can be read simultaneously.
