PROBLEM TO BE SOLVED: To enhance the convenience of a user by performing an appropriate control of a radiation detection part according to a power feeding method by taking into consideration an imaging possible time when feeding a battery.SOLUTION: A radiographic device is provided with a radiation detection part for converting radiation that transmits a subject into an electric charge and can supply power from a battery. The radiographic device includes: a determination part for determining the presence or absence of power supply from an external power source and a control part for controlling a driving of the radiation detection part. The control part controls the driving of the radiation detection part in a first mode which executes a temperature constant driving for maintaining the temperature of the radiographic device when the power supply from the external power source is available and controls the driving of the radiation detection part in a second mode which does not execute the temperature constant driving when the power is not supplied from the external power source and the power is supplied from the battery.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】バッテリ給電時の撮影可能時間を考慮し、給電方法に応じた適切な放射線検出部の制御を行うことで、ユーザの利便性を向上させる。。【解決手段】被写体を透過した放射線を電荷に変換する放射線検出部を備え、バッテリからの電力供給が可能な放射線撮影装置であって、外部電源からの電力供給の有無を判定する判定部と、放射線検出部の駆動を制御する制御部と、を有し、制御部は、外部電源からの電力供給がある場合に、前放射線撮影装置の温度を保持するための温度一定化駆動を実施する第1のモードで放射線検出部の駆動を制御し、外部電源から電力が供給されておらずバッテリから電力が供給されている場合に、温度一定化駆動を実施しない第2のモードで放射線検出部の駆動を制御する。【選択図】 図8
