Abstract
PURPOSE:To obtain a line sensor having a light guide system which is excellent in light utilizability and durable to a high-temperature treatment, by a method wherein a light guide path, surrounded by light reflection layers and corresponding to each of picture elements in the line direction, is formed between two substrates whose light-source sides are transparent. CONSTITUTION:Light reflection layers 13 made of thin metal films are formed between two substrates 11, 12 whose light-source sides are transparent in order to form a light guide path 14 surrounded by the light reflection layers 13 and led to each sensor portion so as to correspond to each of picture elements in the line direction. Each light guide path 14 can be filled with a transparent resin or a transparent adhesive agent. At the bottom of a lght guide portion 5, which contacts with an orginal 4, a transparent protective film 15 is formed. The light 18 from a light source is applied to the original surface and the reflected light 17 is sent to each light receiving portion of a line sensor through the corresponding light guide path 14. Because the light guide path 14 is surrounded by the reflection layers 14, the light utilizability can be made higher, and an improved resolution can be obtained.
