Abstract
A plastic lens array including the following members which are formed integrally as one block by a plastic material; a lens array body member; a plurality of object convex lenses into which the light from an object is made incident, the object convex lenses being arranged side by side in one row along one side of the lens array body member; a plurality of image convex lenses corresponding to the object convex lenses, and being arranged side by side in a row along an opposite side of the lens array body member; a plurality of image inverting portions corresponding to the object convex lenses, each of the image inverting portions having a pair of roof surfaces which are substantially normal to each other to invert the image of an object; a first reflecting surface arranged at the backs of the object convex lenses, for totally reflecting the incident light of an object through the object convex lenses with an angle exceeding a critical angle and for guiding the reflected light of the object to a roof surface in each pair of the roof surfaces; and a second reflecting surface arranged at the backs of the image convex lenses, for totally reflecting the inverted light of an object from the other roof surface in each pair of the roof surfaces with an angle exceeding the critical angle and for guiding the reflected light of an object to the image convex lenses.
