1. A regulating unit for a radiographic imaging system including an X-ray radiation generating apparatus for applying X-ray radiation to an object, said X-ray radiation generating apparatus having an X-ray radiation source and an X-ray radiation source driver for driving said X-ray radiation source, a radiographic imaging apparatus for detecting said X-ray radiation transmitted through said object to create a radiation image, said radiographic imaging apparatus having a radiographic imaging panel, a first AEC signal output device for detecting a dose of said X-ray radiation transmitted through said object to output a first AEC signal for automatic exposure control, said first AEC signal output device being external to said radiographic imaging apparatus, a second AEC signal output device for detecting a dose of said X-ray radiation transmitted through said object to output a second AEC signal for automatic exposure control, said second AEC signal output device being incorporated in said radiographic imaging apparatus, and an exposure control unit for shutting off application of said X-ray radiation from said X-ray radiation source according to said first or second AEC signal from said first or second AEC signal output device, said exposure control unit being disposed with said X-ray radiation source driver, said regulating unit comprising:
an information acquisition device for acquiring at least one of first information of a first switching operation as to whether said first AEC signal output device should be used, second information of a second switching operation as to whether said second AEC signal output device should be used, and information of a connected state as to whether said first and second AEC signal output devices are connected to said X-ray radiation source driver; and a controller for preventing failure of simultaneous inputting of said first and second AEC signals to said exposure control unit according to said information acquired by said information acquisition device. |
