发明名称 LENS ARRAY FOR IMAGE SENSOR AND IMAGE READING APPARATUS INCLUDING THE SAME FOR PREVENTING DETERIORATION OF THE INTENSITY OF RADIATION
摘要 PURPOSE: A lens array for an image sensor and an image reading apparatus including the lens array are provided to restrain the intensity of radiation from being deteriorated due to disagreement of the image sensor and the optical axis of lenses by constructing the lens array of a plurality of lens plates. CONSTITUTION: A lens array(4) for an image sensor is constructed such that a plurality of lens plates(40) are stacked. Each of the lens plates has a plurality of small lenses 2-dimensionally arranged at a predetermined pitch. The lens array includes two or three lens plates. The centers of the small lenses of the upper lens plate correspond to the centers of the small lenses of the lower lens plate.
