PROBLEM TO BE SOLVED: To appropriately protect a scintillator against external impact.SOLUTION: A radiation imaging device (20) has: a contact mechanism (118) for bringing the scintillator and a radiation conversion panel (64) into contact with each other move detecting units (56, 58), which detect move of the radiation imaging device (20) and a contact control unit (110), which controls the contact mechanism (118) so as to bring the scintillator and the radiation conversion panel (64) into contact with each other when radiation is applied to at least a radiation detector, and which stops the control of the contact made between the scintillator and the radiation conversion panel (64) by the contact mechanism (118), when physical quantities relating to the move of the radiation imaging device (20) detected by the move detecting units (56, 58), exceed a predetermined threshold.COPYRIGHT: (C)2012,JPO&INPIT【課題】外部からの衝撃に対してシンチレータを適切に保護する。【解決手段】放射線撮影装置(20)は、シンチレータと放射線変換パネル(64)とを接触させる接触機構(118)と、放射線撮影装置(20)の移動を検知する移動検知部(56、58)と、少なくとも放射線検出器に対する放射線の照射時には、シンチレータと放射線変換パネル(64)とを接触させるように接触機構(118)を制御し、一方で、移動検知部(56、58)が検知した放射線撮影装置(20)の移動に関わる物理量が所定の閾値を超えたときに接触機構(118)によるシンチレータと放射線変換パネル(64)との接触制御を停止させる接触制御部(110)とを有する。【選択図】図7
