Abstract
One of the aspects of the present invention is to provide an X-ray apparatus, which includes an X-ray source radiating an X-ray to a target portion of a person being tested, an X-ray detector detecting the X-ray through the target portion, and a moving mechanism supporting the X-ray source and the X-ray detector so as to oppose to each other. It also includes a driving mechanism driving said moving mechanism so as to keep said X-ray source and said X-ray detector opposing to each other with the target portion intervened therebetween, while the X-ray source radiates the X-ray, and a drive change detector for detecting a drive change of the driving mechanism to determine whether the moving mechanism is applied with an external force preventing motion of the moving mechanism. The driving mechanism is terminated to drive the moving mechanism when the drive change detector detects that the moving mechanism is applied with the external force preventing motion of the moving mechanism.
