Patent ID: 8116599

Claim:
A radiation image signal output control method, comprising the steps of: obtaining by a processor distance information that indicates a distance between an output unit, which reads out image signals from a radiation image recording medium according to a radiation image recorded thereon and outputs the image signals read out therefrom after converting to wireless communication signals, and a receiving unit that receives the wireless communication signals outputted from the output unit; controlling by the processor the wireless communication signals to be outputted from the output unit if the distance indicated by the distance information obtained is less than or equal to a predetermined value, and not to be outputted therefrom if the distance is greater than the predetermined value; temporarily storing image signals read out from the radiation image recording medium according to the radiation image recorded thereon; determining if the image signals temporarily stored in the storage means and outputted from the output unit after converted to wireless communication signals are correctly received by the receiving unit; and making, when the wireless communication signals are determined to have been correctly received by the receiving unit, the image signals temporarily stored in the storage means corresponding to the wireless communication signals correctly received by the receiving means unreadable.
