スウェイトを追加するようにしても良い。In the state shown in FIG. 1, the weight of the C-shaped holding arm 1 on the installation side of the X-ray tube apparatus is (weight of the X-ray tube apparatus 2) and (1/2 of the weight of the high voltage cable 5). (1/2 of the weight of the C-arm). On the other hand, the weight of the C-shaped holding arm 1 on the X-ray detector side is (the weight of the X-ray flat panel detector 3) and (the high-voltage generation unit 4). Weight) and (high voltage cable 5)
Of the C-arm) and (ア ー ム of the weight of the C-arm). Therefore, if (the weight of the X-ray tube device 2) and (the weight of the X-ray flat panel detector 3) + (the weight of the high voltage generation unit 4) can be made equal, the C-shaped holding arm 1 around the XX axis can be obtained. The rotational moment can be balanced. As a result, the operability of the C-shaped holding arm in the direction of rotation with respect to the horizontal rotating shaft 7 (the direction of the XX axis in the drawing) is improved. In addition,
The fine adjustment of the weight of (the weight of the X-ray tube device 2) and (the weight of the X-ray flat panel detector 3) + (the weight of the high voltage generating unit 4) is performed by changing the state of FIG. Is rotated by 90 ° about the X-X axis so that the C-shaped holding arm is in a horizontal state, and the balance in the rotational direction is measured so that a slight shift in the balance around the horizontal rotation axis 7 does not hinder practical operation. X
An auxiliary balance weight may be added to either the tube device side or the X-ray detector side.
