PROBLEM TO BE SOLVED: To correct the sensitivity of an X-ray detector without removing a successive package as a continuous-belt-like inspecting object in which individual packaging parts for storing various products to be conveyed in a production system and boundary parts are alternately disposed at a predetermined interval.SOLUTION: The X-ray inspection device includes: a boundary determination section 5 that detects boundary parts of a successive package W in which a plurality of individual packaging parts for storing contents and the boundary parts are alternately and continuously arranged, and generates and outputs a boundary signal synchronous with the timing at which each boundary part passes a detection region of an X-ray detector 4; and a sensitivity correction processing section 7 for correcting the sensitivity of the X-ray detector 4 by adjusting the gain for each of a plurality of X-ray detection elements included in the X-ray detector 4 on the basis of the detected value of the boundary part acquired by the X-ray detector 4 at the timing of the boundary signal output from the boundary determination section 5. Here, the gain is used for correcting the variation in sensitivity of each element. |
