摘要：
A switching mechanism is configured such that a lower limb radiographic filter 11a is moved inside a radiation field of the X-rays that is an opening portion of an X-ray movable restriction only when radiographing a region of a subject from the groin to the toe, or the filter is moved outside the radiation field when radiographing the lumbar region of the subject. With this switching mechanism thus constituted, it is possible to lighten a burden on the operator, and realize the X-ray radiographic apparatus having high universality.
