Title: Image reader
Inventor: TAKAHASHI TOSHIO
IPC: H04N1/19
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide an image reader which is capable of eliminating moires which are generated when an original is read and also avoiding the harmful effects of directivity of a light guide body by scattering the light reflected on the original surface in an optical path set between the original surface and a lens array. SOLUTION: A light beam that is converted into a linear beam by a light guider 3 is transmitted through a contact glass 2 and irradiated on the printed surface of an original P put on the glass 2. A glass plate 5, which has undergone a light scattering processing, is interposed between an optical path set between the glass 2 and the guider 3 and an optical path set between the glass 2 and a lens array 4. Small spots are formed at random on the surface of the plate 5 in the light scattering processing, so that the directivity of the guider 3 is reduced. In such a constitution of an image reader, the irradiated original image is formed on the surface of a line sensor 6 serving as a photoelectric transducer via the lens array 4. In this case, the original image is transmitted through the display scattering surface of the plate 5 and accordingly the original image blurs slightly.  As a result, moires which are generated when the original P is read can be eliminated.
