PROBLEM TO BE SOLVED: To provide a radiation imaging device that is excellent in load resistance and impact resistance despite being lightweight, and is not easily influenced by heat generated from a power supply unit.SOLUTION: A housing 29 has a monocoque structure including an irradiation surface 36, an opposite surface 44, and a connected surface 46. The housing 29 has a recess 80 that is recessed to be across the opposite surface 44 and the connected surface 46 formed therein. A power supply pack 82 can be attached to the housing 29 via the recess 80. The power supply pack 82 can supply power to a radiation conversion panel 116 in an attached state.COPYRIGHT: (C)2012,JPO&INPIT【課題】軽量でありながら耐荷重性及び耐衝撃性に優れ、且つ、電源部からの発熱の影響を受けにくい放射線撮像装置を提供する。【解決手段】筐体29は、照射面36と、対向面44と、連結面46とを含むモノコック構造を有する。筐体29には、対向面44及び連結面46を跨ぐように凹まされた凹部80が形成されている。凹部80を介して電源パック82を筐体29に装着可能であり、電源パック82は、装着状態下において放射線変換パネル116に電力を供給可能である。【選択図】図4
