Image inspection device and image forming apparatus using the same

Abstract

An image inspection device includes: an illumination part extending in a width direction of a medium, which intersects a medium transport direction, so as to face a medium transport path, and configured to radiate light on an image formed on a surface of the medium; a reading part configured to read reflected light from the image as image inspection information; and a cooling part configured to cool an entire area of the illumination part in the width direction of the medium. The cooling part includes one blowing part provided on one side in the width direction of the medium and configured to suck and blow outside air, a first guide extending in the width direction of the medium and configured to guide the air blown from the blowing part to a flow path extending in the width direction of the medium, and a second guide configured to guide the air, guided by the first guide, in the medium transport direction to a space where the illumination part is disposed, and distribute the air such that an air volume is uniform over the entire area of the illumination part in the width direction of the medium.
