PROBLEM TO BE SOLVED: To improve operability by reducing the possibility that an X-ray tube collides with a structure in a periphery of a monitor or the like in moving.SOLUTION: A movable type X-ray generator as one embodiment in this invention includes: an X-ray tube for irradiating X-rays a collimator disposed in an X-ray irradiating direction of the X-ray tube to limit an X-ray irradiation area an arm supporting the X-ray tube a strut for causing the arm to move in the vertical direction relative to the ground surface a truck part supporting the strut and having movable means and a monitor provided on a top face of the truck part. The X-ray tube has means to rotate at least biaxially for varying an X-ray irradiation direction, and the collimator has means to rotate around the center of X-ray irradiation as the axis. The X-ray tube has means for inhibiting rotation of all of the rotating means when it is put in a storing position in moving the generator.COPYRIGHT: (C)2014,JPO&INPIT【課題】 移動時にX線管球がモニタ等の周囲の構造に衝突する可能性を減らし、操作性を向上させる。【解決手段】 X線を照射するX線管球と、前記X線管球のX線照射方向に配置され、X線照射領域を制限するコリメータと、前記X線管球を支持するアームと、前記アームを地面と鉛直方向に移動可能にする支柱と、前記支柱を支持し、移動可能な手段を有する台車部と、前記台車部の上面にモニタを有する移動型X線発生装置において、前記X線管球は、X線照射方向を変えるために、少なくとも2軸で回転する手段を有し、前記コリメータは、X線照射の中心を軸として回転可能な手段を有し、前記X線管球が装置移動時の収納位置にある場合、前記全ての回転手段の回転を禁止する手段を有することを特徴とする移動型X線発生装置。【選択図】 図1
