PROBLEM TO BE SOLVED: To improve the reliability of operation control at radiography and the safety of the radiographer and the subject when radio communication is applied to a radiographic system by preventing the mix-up of a radiation detector when radio communication is applied to the radiographic system and also reducing the number of system operations when performing radiography.SOLUTION: A setting communication device 11 is provided on a photography stand 1. This allows that when a radiographer mounts a radiation detector 2 in a radiation detector mounting part 3 of the photography stand 1, the photography stand 1 transmits setting information to the radiation detector 2 and a radiographic apparatus 4. The radiographic apparatus 4 receives from a setting communication unit 42 the setting information transmitted by the photography stand 1, and starts radiographic processing by the radiation detector 2, based on the received setting information.SELECTED DRAWING: Figure 2
