Abstract:
1. An image reading device comprising: a light source member having a plate-shaped substrate extending in a predetermined main scanning direction, and a plurality of light source portions releasing light and supported by the substrate in the main scanning direction; a light guide member having an input section disposed facing the light source portions and to which the light released from the light source portions is input, and an output section from which the input light is output, the light guide member guiding the light toward a predetermined radiation position; a support member that supports the light source member and the light guide member and that has higher rigidity than the light guide member and the substrate of the light source member; a first positioning section that is provided in a central area of the support member in the main scanning direction and that positions the light guide member in the main scanning direction and a sub scanning direction intersecting the main scanning direction; a second positioning section that is provided at an end of the support member in the main scanning direction and that positions the light guide member in the sub scanning direction; and a reader member that receives the light from the radiation position so as to read an image of the radiation position, wherein the second positioning section permits the light guide member to move in the main scanning direction.
