ABSTRACT:
An image reading device having a compact plane-shaped illumination portion is provided, by which a portion of a target to be light-irradiated can be irradiated with light whose oblique angles are different from each other, and a transmission part of the target can be read. The image reading device includes a conveying means for conveying in a conveying direction a target to be light-irradiated including a transparent portion, a lens assembly, arranged on one side of the target, for focusing transmission light having passed through the transparent portion of the target, a sensor for receiving the transmission light focused by the lens assembly, a light source, positioned on the other side of the target, arranged in a main-scanning direction, and a light guide for guiding light from the light source in a sub-scanning direction, and the light guide having a reflective portion for reflecting the guided light and then irradiating a portion to be irradiated with the reflected light.
