In the situation where some power supplies are cut off in order to reduce the standby power of the image pickup apparatus, the photographing condition is restricted according to the temperature stabilizing state of the detector, thereby avoiding the possibility of photographing.The range of irradiation of the X-ray tube 1 in accordance with the X-ray tube 1, the bed 4 on which the subject 5 is placed, the detector 2 having the detector 6 for detecting the X-rays from the X-ray tube 1, the rotating disc 3 attached to the X-ray tube 1 and the detecting part 2 in such a manner as to sandwich the bed 4, and the detectable area of the detector The controller 13 has a control unit 13.Diagram【課題】撮像装置の待機電力を削減するために一部の電源を遮断した状況においても、検出器の温度安定状態に応じて撮影条件を制限することで、撮影不可能となることを回避する。【解決手段】X線管1と、被験者5を載せる寝台4と、X線管1からのX線を検出する検出器6を有する検出部2と、寝台4を挟んでX線管1と検出部2とが対向するように取り付けられた回転盤3と、検出器6の撮影可能領域に応じて、X線管1の照射範囲を制御する制御装置13とを有する。【選択図】図8
