And it is an object of the invention after receiving the irradiation start signal, and to provide a radiation image capturing apparatus capable of transmitting the interlock release signal immediately. Control means 22 of the radiation image photographing apparatus 1 therefor, reset process one plane and let me switch 5 are sequentially scan lines to switch between the off-voltage and on-state voltage and the voltage applied from the gate driver 15b of the scan driving unit 15 When to perform a reset process of the radiation detection element 7 while repeatedly and Rm, during the reset process of the radiation detection element 7, through a communication unit 39 during the reset process Rm of the one plane to be repeated When receiving the irradiation start signal, and performs up to the last reset process Rm of one plane such that it is performed at the time of receiving the irradiation start signal, before the end of the reset process Rm in one plane such, in one plane the and transmits an interlock release signal via a communication means 39 at a timing at which the radiation is to be irradiated after the reset process Rm is completed.照射開始信号を受信後、速やかにインターロック解除信号を送信可能な放射線画像撮影装置を提供することを目的とする。そのための放射線画像撮影装置1の制御手段22は、走査駆動手段15のゲートドライバ15bから印加する電圧をオン電圧とオフ電圧との間で切り替える走査線5を順次切り替えさせて1面分のリセット処理Rmを繰り返し行わせながら各放射線検出素子7のリセット処理を行わせと、各放射線検出素子7のリセット処理の際に、繰り返し行う1面分のリセット処理Rmの最中に通信手段39を介して照射開始信号を受信すると、照射開始信号を受信した時点で行っている当該1面分のリセット処理Rmを最後まで行うとともに、当該1面分のリセット処理Rmの終了前に、当該1面分のリセット処理Rmが終了した後で放射線が照射されるようになるタイミングで通信手段39を介してインターロック解除信号を発信する。
