ABSTRACT:
A picture reading apparatus with flaring light elimination capability, which includes a light source for emitting light, a contact glass with which a document to be scanned comes in contact, a lens array in which a plurality of lenses for converging the light from the light source are arranged at equal intervals therebetween, a roof mirror array in which a plurality of roof-like reflection surfaces are arranged corresponding to the plurality of lenses, a restricting plate for eliminating undesired light between adjacent lenses of the lens array, a housing in which the roof mirror array and the lens array are accommodated, a sensor, and a separation mirror. The apparatus further includes a light shield layer provided on the contact glass, at a portion other than a reading portion through which the light from the light source passes to scan the document, for eliminating undesired light, other than the converged light effective in supplying a picture signal.
