ABSTRACT:
An image sensor is provided with a light source for illuminating an original document with light, a plurality of rod lens arrays arranged continuously and connected to each other in such a manner that end rod lenses located at the ends of the rod lens arrays are in contact with each other among rod lenses for forming images of light reflected from the original document, a sealing agent that fills in each of gaps between the end rod lenses, light-receiving elements for receiving image-forming light produced by the rod lenses over a prescribed reading width, and a frame to which the rod lens arrays are fixed via buffers over the prescribed reading width. A long image sensor can be realized at a low cost by using short, general-purpose rod lens arrays.
