Abstract: PROBLEM TO BE SOLVED: To enhance a read image by reducing the illumination fluctuation on the read area. SOLUTION: This image reader provided with a case 1, a plurality of light sources 6 arranged in a column shape in the case 1, a plurality of wall surfaces 15a to 15c which define an optical path 14 for illumination that makes light emitted from the plurality of light sources 6 proceed toward a linear read area S in the case 1 and enable the light to be reflected and a lens array 3 which is for forming the image of an original D arranged in the read area S on a plurality of photodetectors 7, is provided with a light shade 16 preventing the light from directly proceeding toward the area S from each of the light sources 6. A hole part 17 filled up with an adhesive 39 is provided in the case 1 as a means fixing the array 3, and is prevented from being open toward the optical path 14.

Abstract: The present invention is made to provide a fixing structure for solid state image forming device made inexpensively and easily by simple caulking adhering method with keeping high positional accuracy, by which it is achieved that the solid state image forming device can be separated easily from the image focusing lens holding member when the image focusing lens holding member has a defect. In the fixing structure of present invention, an image focusing lens holding member 3 and an intermediate holding member 6 are adhered by caulking adhering method. Because one or more projecting portion 3 c for painting adhesive material formed on the image focusing lens holding member 3, have smaller area than that of bottom surface 6 a of the intermediate holding member 6, a space 10 is formed between the image focusing lens holding member 3 and the intermediate holding member 6, the solid state image forming device 1 fixed on the intermediate holding member 6 can be easily separated from the image focusing lens holding member 3 by inserting and turning a tool 11 whose width of top portion is smaller than the width of space 10.
