PROBLEM TO BE SOLVED: To provide an X-ray photographing device capable of improving workability of registration of route information at the time of X-ray photographing.SOLUTION: An x-ray photographing device 100 includes a control part 6 for, at the time of X-ray photographing a subject S, according to route information based on a representative point registered in advance, controlling a drive part 5 so that an X-ray irradiation part 1, which photographs the subject S, and a top plate 2, on which the subject S is placed, are relatively moved. Then, after the top plate 2 and the X-ray irradiation detection part 1 are relatively moved, on the basis of a fact that the relative movement of the top plate 2 and the x-ray irradiation detection part 1 is stopped or a fact that after the relative movement of the top plate 2 and the x-ray irradiation detection part 1 is stopped, the relative movement of the top plate 2 and the x-ray irradiation detection part 1 is started again, the control part 6 obtains information on a location, at which the relative movement of the top plate 2 and the x-ray irradiation detection part 1 is stopped, as a representative point, and registers route information on the basis of the obtained representative point.SELECTED DRAWING: Figure 4【課題】Ｘ線撮影時の経路情報を登録する作業の作業性を向上させることが可能なＸ線撮影装置を提供する。【解決手段】このＸ線撮影装置１００は、被検体ＳをＸ線撮影する際に、予め登録された代表点に基づく経路情報に基づいて、被検体Ｓが載置される天板２が被検体Ｓを撮影するＸ線照射部１と天板２とが相対移動するように駆動部５を制御する制御部６を備える。そして、制御部６は、天板２とＸ線照射検出部１とが相対移動された後に、天板２とＸ線照射検出部１との相対移動が停止したこと、または、天板２とＸ線照射検出部１との相対移動が停止し、再び天板２とＸ線照射検出部１との相対移動が開始されたことに基づいて、天板２とＸ線照射検出部１との相対移動が停止した位置の情報を代表点として取得するとともに、取得された代表点に基づいて経路情報を登録する。【選択図】図４
