<p>PROBLEM TO BE SOLVED: To enable varied positioning accurately and simply by substantially eliminating the limit to an angle of slide range without worsening accessibility. SOLUTION: An X-ray generation part 12 is rotatably mounted at one end of a C-shaped arm 14 and an X-ray plane detector 16 is mounted at the other end of the C-shaped arm 14 through a freely displaceable link mechanism 20. The X-ray generation part 12 is rotated thereby enabling skew photographing without sliding the C-shaped arm 14. With the rotation of the X-ray generation part 12, the link mechanism 20 is driven to cause a displacement so that the X-ray plane detector 16 faces the X-ray generation part 12.</p> |
