When only it charges, the high-speed charge with heavy-current is possible when and also, it photographs and the like, you take and do and is good, the radiation picture detection system which either deterioration of picture quality does not occur is offered. Because of that, it builds in the battery 28 which, supplies electric power to each functional department from radiation picture detection device 2 of the cassette type where the drive which is due to the electric power supply from of battery 28 is possible and outside in radiation picture detection device 2 electric power supply possible cradle 4 and cable the charge control circuit where controls the charge of 5 and battery 28 and, it has, radiation picture detection device 2 is formed cradle each one of 4 and cable 5 connection electrically and possibly possesses the detection device side connector 26 which does receiving electricity, charge of battery 28 depends on cradle 4It was constituted by both parties of connection and the connection, by cable 5 the constitution which changes charging current possibly as for the charge control circuit 6, at when connecting by cradle 4 and when connecting by cable 5 made.充電のみを行う場合には大電流による高速充電が可能であるとともに、撮影等を行う場合には取り廻しがよく、画質の劣化も生じない放射線画像検出システムを提供する。そのために、各機能部に電力を供給するバッテリ28を内蔵し、バッテリ28からの電力供給による駆動が可能なカセッテ型の放射線画像検出装置2と、外部から放射線画像検出装置2に電力を供給可能なクレードル4及びケーブル5と、バッテリ28の充電制御を行う充電制御回路と、を備え、放射線画像検出装置2は、クレードル4及びケーブル5のそれぞれと電気的に接続可能に構成され受電を行う検出装置側コネクタ部26を有し、バッテリ28の充電は、クレードル4による接続とケーブル5による接続との双方により可能に構成され、充電制御回路6は、クレードル4による接続時と、ケーブル5による接続時とで充電電流を切り替える構成とした。
