    Abstract: PROBLEM TO BE SOLVED: To provide a technique for adjusting a distance between an original platen glass and a closely contact image sensor (CIS) without disassembling an image reading apparatus. SOLUTION: A CIS unit 10 is provided with: a CIS 12; and an elastic body 13 for energizing the CIS 12 toward a direction approaching the platen glass 4. A CIS roller holder 20 is provided with a thin plate-like spacer 22 molded in a rectangular shape; and a CIS holder 21 for holding the spacer 22 movably in a vertical direction and a sub-scanning direction for the platen glass 4 and to be fixed on the CIS unit 10. Meanwhile, a concave and a convex which can be mated are formed on a surface where the CIS holder 21 opposes the spacer 22. When the CIS unit 10 moves in the sub-scanning direction and the CIS roller holder 20 abuts on a rib 7a (rib 7b), the convex portion of the CIS holder 21 abuts on the concave portion (convex portion) of the spacer 22, and thus, the distance the platen glass 4 and the CIS 12 becomes the shortest.

    Abstract: PROBLEM TO BE SOLVED: To solve the problem in which a locally thick part becomes a weak point to easily cause mechanical resonance vibration from an image reader and then picture quality deteriorates as the locally thick part is formed as a substrate for fitting and a mask are adjacent to each other when the image reader is made small-sized, while a resin-made lens block is equipped with a mask for shading correction integrally and the mask has an aperture increasing in size toward an end in a main scanning direction to capture more marginal light flux than center luminous flux. SOLUTION: At a center part of a mask part 202, upper and lower light shield parts 202a cut off upper and lower parts of light flux 103 of the center part incident on a lens block 201 and parts of ends of the mask part 202 are formed of an arcuate connection part 202b for pieces 104 and 105 of light flux incident from the end, so that the light flux is all incident and a large thickness is obtained with a fitting part 201a.

    SOLUTION: The reading module is provided with a light source 5, a pair of mirrors consisting of a mirror 11 which reflected light from an original 20 is made to enter and a mirror 12 whose mirror surface is opposed to that of the mirror 11 nearly parallel therewith at a specified interval therefrom, and reflecting the incident light several times and then emitting it from the mirror 11, a mirror 13 reflecting the light entering from a pair of mirrors nearly in parallel with the original 20 in a direction where the light goes away from a pair of mirrors, a mirror 14 reflecting the light entering from the mirror 13 in a direction where the light is nearly opposed to the light going toward the mirror 13 from a pair of mirrors, and making the light enter a lens 2, a mirror 15 reflecting the light emitted from the lens 2 in a direction where the light is nearly opposed to the light going toward the mirror 14 from the mirror 13, and a linear sensor 1 arranged at given intervals from the mirror 15. The position of a pair of mirrors can be changed along an optical path going toward the mirror 11 from the original 20 while holding positional relationship between the mirrors 11 and 12.
