<P>PROBLEM TO BE SOLVED: To make illuminance at an inner face of a tire 12 to be uniform while performing imaging even when the tire 12 to be inspected is changed. Ž<P>SOLUTION: When an area camera 46 is moved by a second movement means 47, a light source 40 is moved together with the area camera 46. Therefore, even when a size of a tire 12 is changed, the light source 40 is always positioned at an irradiation position C that is away from an inner circumference of the tire 12 at a constant distance to the inside in its radial direction when performing the imaging. As a result, a distance from the light source 40 to the inner face of the tire 12 is roughly constant while performing the imaging, thereby effectively enhancing inspection accuracy.
