RADIOGRAPHIC IMAGING DEVICE

In the radiographic imaging device, a portion of a second effective imaging region at a first side or a second side of a sensor unit of a second radiation detection panel, and a portion of a first effective imaging region at a third side or a fourth side of the sensor unit of a first radiation detection panel, are overlapped in a radiation irradiating direction. A portion of a second effective imaging region at the third side or the fourth side of the sensor unit of the second radiation detection panel, and a portion of a third effective imaging region at the third side or the fourth side of the sensor unit of the third radiation detection panel, are overlapped in the radiation irradiating direction. The second radiation detection panel is disposed at a side opposite the radiation irradiating section side of the first radiation detection panel and the third radiation detection panel.
