The position of the X-ray irradiation unit 3 at this time is detected by an X position detector 57 shown in FIG.
- the movement of the X-ray irradiation unit 3 in the X direction at this time is caused by the positional information of the X-ray tube 31 detected by the X position detector 57 and the X-ray detector storage unit 6 detected by the potentiometer 24.
- Position information, dimension information in the body axis direction of the subject M of the flat panel detector 7 housed in the X-ray detector housing section 6 detected by the potentiometer 64, and the reference position stored in the reference position information storage section 101 This is executed based on the information and the maximum dimension information stored in the maximum dimension information storage unit 102.
- the dimension of the subject M in the body axis direction of the flat panel detector 7 stored in the X-ray detector storage unit 6 is the same as that of the flat panel detector 7 that can be stored in the X-ray detector storage unit 6.
- the position of the X-ray storage unit 6 may be moved in the X direction by a distance corresponding to the movement distance of the X-ray irradiation unit 3 in the X direction by the moving mechanism 23.
- the flat panel detector 7 is used as the X-ray detector.
- other X-ray detectors such as a cassette and CR may be used, and those X-ray detectors may be used. You may replace the vessel.
