<p>A radiation imaging device is provided with heat-retention means for retaining radiation detecting means in a predetermined temperature range during nonuse of the radiation imaging device, so that a radiation detecting unit can avoid temperature changes beyond a predetermined range which are caused by the nonuse of the radiation imaging device and, so that radiation detecting means can be kept warm stably. Further, in order for the heat-retention means to operate during the nonuse of the radiation imaging device, the control of power supply for the heat-retention means is independent of that of driving power supply for the radiation imaging device. Due to those controls, heat-retention means can be continuously supplied with power even when the driving power supply to the radiation imaging device is stopped at the nonuse.</p> |
