PROBLEM TO BE SOLVED: To provide a radiographic imaging device and communication mode setting device for establishing wireless communication with a controller to be a communication target even in a bad communication state when communication is performed via another wireless device in an indirect communication mode.SOLUTION: When a setting to carry out communication in an ad hoc mode has been made, wireless communication is performed in the ad hoc mode. When a setting to carry out communication in an infrastructure mode has been made, wireless communication with a console 18 being a communication target is attempted in the infrastructure mode. When the communication is impossible, wireless communication is performed in the ad hoc mode.COPYRIGHT: (C)2012,JPO&INPIT【課題】間接通信モードとされて他の無線機器を介して通信が行われる際に通信状況が悪い場合でも、通信対象となる制御装置と無線通信を確立することができる放射線画像撮影装置及び通信モード設定装置を提供する。【解決手段】アドホックモードで通信を行う指定がされている場合はアドホックモードで無線通信を行い、インストラクチャモードで通信を行う指定がされている場合はインストラクチャモードで通信対象のコンソール18と無線通信を試み、通信不能の場合にアドホックモードで無線通信を行う。【選択図】図12
