PROBLEM TO BE SOLVED: To provide a radiation image photographing device and a charging system by which a radiation image with proper image quality can be acquired even when a charging circuit part included in the radiation image photographing device generates heat.SOLUTION: A radiation image photographing device 2 which includes respective function parts executing predetermined functions regarding radiation image photography and a power storage body 28 supplying power to the respective functional parts, inside a casing 21, and which can be driven by power supply from the power storage body 28. The radiation image photographing device 2 includes: a charging circuit part 6 which supplies charged power to the power storage body 28 a first temperature detection part 81 which detects temperature of the charging circuit part 6 and/or its periphery and a second temperature detection part 82 which detects temperature of a place distant from a place where the temperature is detected by the first temperature detection part 81 by a predetermined distance or more, determines whether or not a difference between the temperature detected by the first temperature detection part 81 and the temperature detected by the second temperature detection part 82 is equal to or more than a first threshold S1, and when the difference is equal to or more than the first threshold S1, reduces the charged power to be supplied to the power storage body 28.COPYRIGHT: (C)2012,JPO&INPIT【課題】放射線画像撮影装置が備える充電回路部が発熱しても、適切な画質の放射線画像を取得することが可能な放射線画像撮影装置及び充電システムを提供する。【解決手段】放射線画像撮影に関する所定の機能を実行する各機能部と、各機能部に電力を供給する蓄電体28とを筐体21内部に備え、蓄電体28からの電力供給による駆動が可能な放射線画像撮影装置2において、蓄電体28に充電電力を供給する充電回路部6と、充電回路部6及び/又はその周辺の温度を検出する第1温度検出部81と、第1温度検出部81により温度が検出される場所から所定の距離以上離れた場所の温度を検出する第2温度検出部82と、を備え、第1温度検出部81により検出された温度と第2温度検出部82により検出された温度との差が第1閾値S1以上であるか否かを判定し、当該差が第1閾値S1以上である場合に蓄電体28に供給する充電電力を低下させることを特徴とする。【選択図】図1
