There is described a radiographic imaging system to read radiation image stored in a radiation-image storing sheet. The radiographic imaging system includes a plurality of controllers, each of which has an image-display section; a plurality of radiation-image reading apparatus to read a radiation image stored in a radiation-image storing sheet so as to generate image data; and a network to link the plurality of controllers and the plurality of radiation-image reading apparatus; wherein the controller requests a radiation-image reading apparatus to transmit the image data, read by the radiation-image reading apparatus, to the controller. The radiation-image reading apparatus reads a sheet-discrimination information in regard to each of the radiation-image storing sheets, and transmits the sheet-discrimination information to the plurality of controllers, and one of the controllers requests the radiation-image reading apparatus to transmit the image data to the controller, based on the sheet-discrimination information sent from the radiation-image reading apparatus.
