PROBLEM TO BE SOLVED: To stably detect that a radiographic imaging device has been mounted on an imaging platform.SOLUTION: A radiographic imaging system includes a radiographic imaging device for capturing a radiographic image, an imaging platform for holding the radiographic imaging device, and an external processing device for acquiring image data by the imaging of the radiographic imaging device. The radiographic imaging device includes a mounting detection part 225 for detecting that the radiographic imaging device has been mounted on the imaging platform, a first radio communication part 292 for performing radio communication with the external processing device, and a second radio communication part 293 for performing shorter-range radio communication than the first radio communication part. The radiographic imaging device starts power supply to the second radio communication part after the mounting detection part detects that the radiographic imaging device has been mounted on the imaging platform.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】放射線画像撮影装置の撮影台への装着を安定的に検出する。【解決手段】放射線画像の撮影を行う放射線画像撮影装置と、放射線画像撮影装置を保持する撮影台と、放射線画像撮影装置の撮影による画像データを取得する外部処理装置とを備え、放射線画像撮影装置は、撮影台への装着を検出する装着検出部２２５と、外部処理装置との無線通信を行う第一の無線通信部２９２と、第一の無線通信部よりも近距離の無線通信を行う第二の無線通信部２９３とを備え、放射線画像撮影装置は、装着検出部により撮影台への装着が検出された後に第二の無線通信部への電源供給を開始する。【選択図】図６
