To provide an X-ray radiotography apparatus capable of quickly and securely fixing a subject at the time of photographing and preventing an operator from exposure without hindering the photographing even when a subject holding means is not used.
In the X-ray radiotography apparatus, X rays emitted from an X-ray generating means are applied to the subject, and the distribution of X rays penetrating the subject is detected by a sensor. The X-ray radiotography apparatus comprises an X-ray detecting means with a detection face where a plurality of detectors are two-dimensionally disposed, a fixing means for fixing the subject being photographed, and a means for storing the fixing means. The X-ray radiotography apparatus also has an energizing means for energizing the fixing means in the direction of storing the fixing means and a locking means for preventing movement of the fixing means from the storing means.
