Claim One:
1. An image reading apparatus comprising: a light source configured to apply light to a section to be imaged of a document; an imaging optics system configured to form an image upon condensing scattered light of the light reflected by the section, the imaging optics system including a plurality of cells which are arranged in a main scanning direction, each of which is independent from each other and includes a telecentric optics system at the side of the document, wherein the cells are arranged in a sub-scanning direction in two rows of a first row and a second row, and are arranged such that light beams among chief rays of the cells arranged in a same row, light beams being directed from the document to the cells, are in parallel with each other, and wherein the cells in the first row and the second row are arranged zigzag in the main scanning direction so as to complement a formed image by the cells in the sub-scanning direction; a plurality of image pickup device units arranged to correspond to the respective cells; a memory configured to store image information transmitted from image pickup device units corresponding in the sub-scanning direction; a processor configured to create a document image by combining images obtained from neighboring cells in the sub-scanning direction so that images in overlapped areas of the neighboring cells in the sub-scanning direction match with each other; and a light shielding member inserted between the cells in the main scanning direction.
