PROBLEM TO BE SOLVED: To provide a radiation image detecting device capable of surely fixing a battery.SOLUTION: A radiation image detecting device 1 comprises: a radiation image sensor 2 that detects radiation and generates image data a housing 4 that stores the radiation image sensor: a battery 5 that is stored in a battery storage part 14 provided in the housing and supplies the radiation image sensor with operating power and a plurality of locking mechanism 40 that lock the battery 5 stored in the battery storage part. Each of the locking mechanisms 40 includes an engaging member 43 that is moved between an engagement position to be engaged with the battery, and a non-engagement position. The engaging member has an operating part 42 exposed to the outer face of the housing part in which the battery storage part is provided. The plurality of locking members include one or more first locking mechanisms in which the moving direction of the engaging member from the engagement position to the non-engagement position is defined as a first direction D1 and one or more second locking mechanisms in which the moving direction is defined as a second direction D2 that is different from the first direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】バッテリーの固定を確実に行うことができる放射線画像検出装置を提供する。【解決手段】放射線画像検出装置1は、放射線を検出して画像データを生成する放射線画像センサ2と、前記放射線画像センサを収容する筺体4と、前記筐体に設けられたバッテリー収容部14に収容され、前記放射線画像センサに動作電力を供給するバッテリー5と、バッテリー収容部に収容された前記バッテリーを係止する複数のロック機構40と、を備え、前記ロック機構の各々は、前記バッテリーに係合する係合位置及び非係合位置の間で移動される係合部材43を有し、該係合部材には、前記バッテリー収容部が設けられた筐体部分の外面に露出する操作部42が設けられており、前記複数のロック機構は、前記係合部材の前記係合位置から前記非係合位置への移動方向が第1方向D1に設定された第1ロック機構、及び前記第1方向とは異なる第2方向D2に設定された第2ロック機構を、それぞれ一つ以上含む。【選択図】図11
