摘要

This specification discloses a lens array having a lens element body having a plurality of lens elements arranged, and an overlap limiting member provided between the lens elements of the lens element body for limiting the overlap of images by the plurality of lens elements. The specification also discusses a close contact type image sensor which uses the lens array as an optical element array for directing reflected light from an original and which has a transparent member for supporting the original, a light source for illuminating the original, and a sensor array for photoelectrically converting the image of the original.
