Claim:
1. An X-ray apparatus comprising: an X-ray source for emitting X-rays toward an inspection object; an X-ray source mover for moving the X-ray source along a body axis of the inspection object; an X-ray detector disposed opposite the X-ray source for detecting X-rays transmitted through the inspection object and outputting them as X-ray images; an X-ray detector mover for moving the X-ray detector along the body axis of the inspection object independently of the X-ray source; a collimator disposed on an X-ray emitting side of the X-ray source to be movable with the X-ray source for contracting emitted X-rays; an X-ray irradiation area discriminator for discriminating, for separate X-raying actions, X-ray irradiation area images which are areas of the X-ray images where X-rays collimated to an area narrower than a detecting area of the X-ray detector in a direction of movement of the X-ray detector are received; a position information acquirer for acquiring position information on the X-ray source for the separate X-raying actions; and a long image creator for creating a long image by shifting the X-ray irradiation area images based on the position information on the X-ray source acquired by the position information acquirer and regardless of a relative moving distance of the X-ray detector, so that a center of each of the X-ray irradiation area images in the direction of movement of the X-ray detector coincide with a position of X-ray incidence at a time of radiography, and by splicing the X-ray irradiation area images together.
