PROBLEM TO BE SOLVED: To improve operability when moving a radiation generator.SOLUTION: An X-ray generator 14 is held to be movable in the X-axis, Y-axis, and Z-axis directions, and is held to be rotatable around the X-axis. An operating device 13 includes a device body 41 that is shaped in a plate shape and is coupled to the X-ray generator 14, and gripping portions 42 that are formed integrally with the device body 41. The device body 41 is provided with direction-selecting buttons 43a-43d and release buttons 44a-44b. The direction-selecting buttons 43a-43d are operated to select directions in which the movement and rotation of the X-ray generator 14 will be free. The movement and rotation of the X-ray generator 14 in directions that have been selected by the direction-selecting buttons 43a-43d are set to be free when at least one of the release buttons 44a-44b is pressed.COPYRIGHT: (C)2013,JPO&INPIT【課題】放射線発生器を移動させるときの操作性を向上させる。【解決手段】X線発生器14はX軸、Y軸及びZ軸方向に移動可能、及びX軸回りに回転可能に保持される。操作装置13は、板状に形成され、X線発生器14と結合された装置本体41と、装置本体41と一体に形成された把持部42とを備える。装置本体41は、方向選択ボタン43a~43d、解除ボタン44a,44bが設けられる。方向選択ボタン43a~43dは、X線発生器14の移動及び回転がフリーになる方向を選択するために操作される。解除ボタン44a,44bが押圧操作されたとき、方向選択ボタン43a~43dで選択された方向におけるX線発生器14の移動及び回転がフリーになる。【選択図】図2
