PROBLEM TO BE SOLVED: To allow an alarm notifying an operator of operation status of an X-ray irradiation part to be installed in an examination room, to allow the operator to easily confirm the status of the X-ray irradiation part even when the operator is away from an X-ray control part or a monitor, and to allow the alarm notifying the operator of the operation status of the X-ray irradiation part to be installed later.SOLUTION: An X-ray diagnostic apparatus includes: an X-ray irradiation part 11 an X-ray imaging part 12 a monitor 8 displaying an X-ray image photographed a monitor holder 7 holding the monitor 8 and a monitor holder support mechanism 6 supporting the monitor holder 7 in a movable manner from a ceiling. Above the monitor holder 7 and below a holding part 16 of the monitor holding apparatus support mechanism 6, an alarm 20 or a cover body in the same shape as the alarm 20 can be detachably installed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】検査室内にX線照射部の作動状況を報知する報知器を設置可能とし、操作者がX線制御部やモニタから離れたところにいても、容易にX線照射部の状況を確認できるようにすること及びX線照射部の作動状況を報知する報知器を後付けできるようにすること。【解決手段】X線照射部11と、X線撮影部12と、撮影されたX線画像を表示させるモニタ8と、モニタ8を保持するモニタ保持装置7と、モニタ保持装置7を天井から移動可能に支持するモニタ保持装置支持機構6を備え、モニタ保持装置7の上方でモニタ保持装置支持機構6の保持部16の下方に、報知器20又は報知器20と同じ形状のカバー体が着脱自在に設置可能であるX線診断装置。【選択図】図1
