As dissipation power of the portable die x-ray device is suppressed, in the portable die x-ray device which has with the standards 6 which the portable die x-ray device which suppresses the noise of the rotating anode of the X-ray tube and in order to offer rotating anode control manner, computer the winch the x-ray generation section the x-ray operational diaphragm 3 which adjusts the irradiation field of 2 which possesses the X-ray tube 20 which generates 4 which loads 1 and computer 1 and the x-ray and the x-ray and x-ray generation section the arm are installed on 5 which supports 2 and x-ray operational diaphragm 3 and winch 4, support arm 5, winch 4Or when x-ray generation section 2 is made to move, it has the rotating anode Drive section braking the revolution of the rotating anode of X-ray tube 20. Depending, as you suppress the dissipation power of the portable die x-ray device, it can suppress the noise of the rotating anode of the X-ray tube.移動型X線装置の消費電力を抑制するとともに、X線管の回転陽極の騒音を抑制する移動型X線装置及び回転陽極制御方法を提供するために、本体1と、本体1を搭載する台車4と、X線を発生させるX線管20を有したX線発生部2と、X線の照射野を調整するX線可動絞り3と、X線発生部2及びX線可動絞り3を支持するアーム5と、台車4上に設置され、アーム5を支持する支柱6とを備える移動型X線装置において、台車4又はX線発生部2を移動させる場合、X線管20の回転陽極の回転を制動させる回転陽極駆動部を備える。よって、移動型X線装置の消費電力を抑制するとともに、X線管の回転陽極の騒音を抑制することができる。
