<P>PROBLEM TO BE SOLVED: To provide a radiographic device capable of acquiring tomographic images of excellent visibility by freely changing the rotation mode of a C-shaped arm 7 to achieve the magnification change of a subject M projected on an FPD (flat panel detector) 4. Ž<P>SOLUTION: The radiographic device has the C-shaped arm 7 and a post 8 supporting the C-shaped arm 7 through a pivot Q. When the C-shaped arm 7 is rotated, the pivot Q moves. The C-shaped arm 7 is rotated around the pivot Q, but since the pivot Q also moves, a distance between an interest portion of the subject M and an X-ray tube 3 is not limited to one distance, that is, the radiographic device is capable of adjusting the distance between the subject M and the X-ray tube 3 according to the purpose of examination.
