PROBLEM TO BE SOLVED: To provide an X-ray radiographic apparatus with high versatility which relieves burden on an operator. SOLUTION: A changeover mechanism 12 is constituted to move a lower limb radiographing filter 11a into an X-ray irradiation visual field being the opening 10a of an X-ray mobile diaphragm 10 only when a part lower than the inguinal region of an examinee is radiographed, or to move the filter 11a to the outer part of the irradiation visual field when a waist part is radiographed. The changeover mechanism 12 is constituted in this way, so that burden on the operator is relieved, and also the X-ray radiographic apparatus with high versatility is achieved. COPYRIGHT: (C)2004,JPO
