The object of the present invention is carried out and accurately reset process for each radiation detection element, after receiving the irradiation start signal, and to provide a radiation image capturing apparatus capable of transmitting the interlock release signal immediately, the radiation image photographing apparatus 1, the scanning reset of the radiation detection element 7 which is performed while repeatedly reset processing Rm of the 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 drive means 15 In stage during the process, the charge remaining in the radiation detection element 7 reaches the charge amount Qa given, is caused to perform reset processing Rm in one plane and thereby reducing the on-time, via the communication means 39 When receiving the irradiation start signal, upon exiting the reset process Rm of the one plane on-time is shortened, and the OFF state of each switch means 8 by an OFF voltage is applied to the scanning lines 5 from all the gate driver 15b The causes are, to transmit an interlock release signal via a communication means 39.各放射線検出素子のリセット処理を的確に行うとともに、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し、放射線画像撮影装置1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行う各放射線検出素子7のリセット処理の際に、各放射線検出素子7内に残存する電荷が所定の電荷量Qaになった段階で、オン時間を短縮させて1面分のリセット処理Rmを行わせ、通信手段39を介して照射開始信号を受信すると、オン時間が短縮された1面分のリセット処理Rmを終了した時点で、ゲートドライバ15bから全ての走査線5にオフ電圧を印加させて各スイッチ手段8をオフ状態とさせるとともに、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。
