摘要： An apparatus for X-ray photographing a tire and method utilizing the apparatus, capable of acquiring excellent image with no distortion nor blur of the full circumference and full width of the tire, are provided. Regarding a X-ray photographing-tire apparatus 10, defining the reference plane H as the plane perpendicular to the center axis C of a tire mounted on a rotary device and passing through the X-ray source 2, and defining the reference line L as the line headed from the center axis C to the X-ray source within the reference plane H, the X-ray source 2 is oriented so that a predetermined azimuth range coincides with a predetermined angular range in which the reference line L lies, within the reference plane H, and said X-ray source is movable along on the reference line L according to the size of the tire mounted on the rotary device, so that it can be placed at the nearest position to the inner surface of the tread portion as long as a predetermined elevation angle range covers the angular range including both bead cores BC with the tread portion in between, and the line-sensors 3, 4, 5 are oriented so that at the plane including X-ray source 2 and perpendicular to the longitudinal direction of each of the line-sensors 3, 4, 5, the light receiving surface is perpendicular to the line headed to the X-ray source 2, and a first line-sensor, being oriented parallel with the center axis C, is placed within said predetermined azimuth range, in the radial outside of the tread portion TR of the tire mounted on the rotary device, second and third line-sensors, being disposed on the line formed by moving the reference line L in parallel in the direction of the center axis C, in the lateral outside of the respective sidewall portions S of the tire mounted on the rotary device, and the first line-sensor is placed at the position deviated from the plane defined by both reference line L and the center axis C, having two degrees of freedom of motion within the reference plane H, so that it can be as close as possible to the outer surface of the tread portion TR of the tire according to the size of the tire mounted on the rotary device, with orientation of said receiving surface 3a kept constant, and the second and third line-sensors 4, 5 are movable in the direction of the center axis C according to the size of the tire mounted on the rotary device, so that it can be as close as possible to respective sidewall portions S of the tire.
