PROBLEM TO BE SOLVED: To form an opening for replacing at least a power source part on a housing while ensuring the rigidity of the housing of monocoque structure.SOLUTION: A radiation imaging apparatus (20A) comprises: a radiation conversion panel (116) for converting radiation (16) to a radiation image a power source part (94) for supplying power to the radiation conversion panel (116) and a housing (29) with monocoque structure accommodating the radiation conversion panel (116) and the power source part (94). Among a plurality of surfaces (36, 46, 52, and 81) composing the housing (29), an opening (98) in which at least the power source part (94) is attached to or detached from the housing (29) is formed in the vicinity of the central part of one surface other than an irradiation surface (36) which is able to transmit the radiation (16).COPYRIGHT: (C)2012,JPO&INPIT【課題】モノコック構造の筐体の剛性を確保しつつ、少なくとも電源部を交換するための開口部を前記筐体に形成する。【解決手段】放射線撮像装置(20A)は、放射線(16)を放射線画像に変換する放射線変換パネル(116)と、前記放射線変換パネル(116)に電力を供給する電源部(94)と、前記放射線変換パネル(116)及び前記電源部(94)を収容するモノコック構造の筐体(29)とを備え、前記筐体(29)を構成する複数の面(36、46、52、81)のうち、前記放射線(16)を透過可能な照射面(36)以外の一面の中央部近傍には、前記筐体(29)に対して少なくとも前記電源部(94)を着脱可能な開口部(98)が形成されている。【選択図】図9
