Abstract

PURPOSE:To eliminate inconvenience by interference light, etc. so as to provide suitability for a transmission system, such as facsimile, etc., by providing plural indentations on the surface of a light-pervious substrate, providing their insides with their respective light-receiving elements, placing a script or a typescript directly on this surface and providing a lighting source under the substrate. CONSTITUTION:Plural indentations are formed on the surface of a light-pervious substrate 7, this bottom surface and side surface are covered with a light-shielding layer 11 consisting of opaque metallic membranes capable of preventing an interference light 10', and a transparent insulation membrane 12' is attached to this surface. And then, insides of the indentations are provided with their respective light-receiving elements 8, and the insides are also filled with a transparent protective membrane 9. In such a constitution of a light-electricity converter, a script or a typescript 1 is placed on the light-receiving 8, a lighting source 2 such as a fluorescent light under the substrate 7. And then, a light 10 from the lighting source 2 is passed through the substrate 7 in the neighborhood of the indentations and applied onto the script 1, a reflection light 10'' is made to enter the element 8, and the interference light 10' entering the reverse surface of the element 8 is shielded by the light-shielding layer 11. It is possible, by doing so, to improve the assembling accuracy and the photo-reading performance.
