PROBLEM TO BE SOLVED: To enable an operator to perform radiography easily with the x-ray irradiation timing matching the radiographing timing without synchronizing a radiation generator with a radiographic device and further without depending on irradiation conditions.SOLUTION: A radiographic device comprises a setting unit 260 for setting a timing of performing radiographing by a radiographic device 200 and an operation unit 250 for generating a signal for starting radiographing. Control is implemented so that an accumulation operation by a radiation sensor 210 is performed after the set time from an operation of the operation part 250.
