<p>An image reading device (Sc) includes a light source member (7), a light guide member (71), a support member (42), a first positioning section (47), a second positioning section (48), and a reader member (18, 27). The light source member (7) has a plate-shaped substrate extending in a predetermined main scanning direction and multiple light source portions (62) releasing light and supported by the substrate in the main scanning direction. The light guide member (71) has an input section (73a) disposed facing the light source portions (62) and to which the light released from the light source portions (62) is input, and an output section (73b) from which the input light is output. Moreover, the light guide member (71) guides the light toward a predetermined radiation position. The support member (42) supports the light source member (7) and the light guide member (71) and has higher rigidity than the light guide member (71) and the substrate of the light source member (7). The first positioning section (47) is provided in a central area of the support member (42) in the main scanning direction and positions the light guide member (71) in the main scanning direction and a sub scanning direction intersecting the main scanning direction. The second positioning section (48) is provided at an end of the support member (42) in the main scanning direction and positions the light guide member (71) in the sub scanning direction. The reader member (18,27) receives the light from the radiation position so as to read an image of the radiation position.
