PROBLEM TO BE SOLVED: To provide a radiographic apparatus capable of preventing collision of a radiation detector with an obstruction.SOLUTION: A flat panel detector 32 is connected to a spindle 41 oriented in a vertical direction with respect to an X-ray detection surface 38. The spindle 41 is rotatably supported by action of a bearing 42, and the flat panel detector 32 rotates around the spindle 41 by drive of a motor 45 via the spindle 41. A frame member 33 surrounding the flat panel detector 32 has a circular external shape, with the spindle 41 used as a center. The outside diameter of the frame member 33 is configured to be larger than the length of a diagonal line of the flat panel detector 32.SELECTED DRAWING: Figure 4
