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 lumber region of the subject. With this switching mechanism thus
constituted, it is possible to lighten a burden of the operator, and realize the
X-ray radiographic apparatus having high universality.
