PROBLEM TO BE SOLVED: To reduce an operators double effort and wasteful exposure of a subject to radiation by improving continuity of photographing during radiation split photographing.SOLUTION: When split photographing continues, a state of an irradiation switch for giving instructions on exposure to radiation is detected by irradiation switch state detection means. When the stop of the instructions on the exposure to the radiation is detected, information for urging the photographing to be continued, done over again and discontinued is shown to an operator to avoid an unintended interruption of the photographing.COPYRIGHT: (C)2015,JPO&INPIT【課題】放射線の分割撮影時における撮影の継続性を高め、操作者の二度手間や被写体への無駄な被曝を軽減する。【解決手段】分割撮影を継続中、照射スイッチ状態検知手段によって放射線照射を指示する照射スイッチの状態を検出し、放射線照射の指示の停止を検出すると、撮影の継続、撮影のやり直し、撮影の中止を促す情報を操作者に示すことで、意図しない撮影の中断を避ける。【選択図】 図5
