Abstract:
1. A radiation image capturing device comprising: a detection section including: a switch section provided for each of the radiation detection elements, wherein when an ON-state voltage is applied to the scan lines to which the switch section is connected, the switch section discharges electric charge generated in the radiation detection elements, and when an OFF-state voltage is applied to the connected scan lines, the switch section accumulates the electric charge in the radiation detection elements, the electric charge being generated in the radiation detection elements; a scan driving section including: a current detection section which detects a current flowing in the device by irradiation; and a control section which detects at least a start of the irradiation based on a current value of the current detected by the current detection section, wherein the control section applies the ON-state voltage having a predetermined voltage value from the scan driving section to the switch section via each of the scan lines simultaneously so as to perform reset processing of each of the radiation detection elements before radiation image capturing, and thereafter, decreases the voltage value of the ON-state voltage simultaneously, monitors the current value outputted from the current detection section while keeping the decreased voltage value of the ON-state voltage, and waits for the start of the irradiation.
