Abstract
An color image reader according to the present invention includes a holding glass for holding an object, the holding glass being a rectangular, plate-like, flat member having a pair of long sides and a pair of short sides perpendicular to each other at right angles, an illuminating unit having an xenon lamp and a reflector both for illuminating the object placed closely on one side of the holding glass, the xenon lamp emitting light toward an irradiation range to irradiate the object, and the reflector having a first reflection plane and a second reflection plane to irradiate the irradiation range in a direction along the planes of the holding glass from a direction opposite to a direction of the light emitted from the xenon lamp, a reduction lens for providing an image-forming characteristic to light reflected by the object on the holding member illuminated by the illuminating unit, and a CCD sensor for receiving the reflected light to which the reduction lens provides the image-forming characteristic, and outputting an electrical signal corresponding to the reflected light. Even though a document to be read is formed by pasting two sheets and thus has a step, a shade can be prevented from occurring in the step.
