In addition to the case where it is necessary to bring the X-ray tube device 18 close to the ceiling in order to perform this, a positioning operation will be described, such as when imaging the opposite side (back side) of the subject 100 from the operator 200 by shaping or the like.

  In this case, the operator 200 wraps around the auxiliary operation device 22 disposed on the opposite side of the subject 100 and operates the auxiliary operation device 22 from a distance behind the subject 100. The X-ray tube device 18 is moved by pushing, pulling, lowering, raising, or turning the operation handle 224 while pressing various lock release buttons of the operation switches provided on the panel 222. The position and orientation of the X-ray tube device 18 are adjusted appropriately. Specifically, the operator 200 unlocks the first movable free button, the second movable free button, and the vertical movement free button of the operation switch provided on the operation panel 222 of the auxiliary operation device 22 (lock OFF). After that, the operation handle 224 is grasped, and the X-ray tube device 18 on the main controller 20 side is moved to a vicinity of a predetermined part of the subject 100 placed on the imaging table 300. Next, while holding the operation handle 224, the operator 200 locks on all of the first, second movable and up / down free buttons, and also locks off the first to fourth rotation free buttons. Is rotated about the vertical axis Va, the connecting arm 12 is rotated about the first horizontal axis La1, and the rotating arm 15 is rotated about the first horizontal axis La1 or the second horizontal axis La2.
