PROBLEM TO BE SOLVED: To provide radiographic apparatus capable of improving a radiographing throughput and elongating the service life of a radiation field lamp by lighting the radiation field lamp only in adjusting the X-ray radiation field.SOLUTION: A subject 1 is irradiated with X-rays from an X-ray generation device 2, a radiographing area of a subject 1 is irradiated with light of the radiation lamp 3 when adjusting the X-ray irradiating range and the X-ray irradiation field is adjusted by an X-ray variable diaphragm device 4. This radiographic apparatus is provided with an X-ray radiation field adjustment finish signal detecting means detecting the finish of the X-ray irradiation field adjustment, and an irradiation field lamp lighting time control means controlling the lighting time of the radiation field lamp 3 corresponding to the X-ray irradiation field adjustment finish signal detected by the detecting means. The X-ray irradiation field adjustment finish signal detecting means has an operation detecting device 8 detecting the mechanical operation of a radiographing mechanism, and the irradiation field lamp lighting time control means has an irradiation field lamp control device 9 turning off the irradiation field lamp 3 by the finish signal of the mechanical operation.COPYRIGHT: (C)2007,JPO&INPIT【課題】 X線の照射野調整の間のみ照射野ランプを点灯して、撮影スループットの向上及び照射野ランプの寿命を長くすることが可能なX線撮影装置を提供する。【解決手段】 X線発生装置2から被検者1にX線を照射し、このX線の照射範囲を照射野ランプ3の照射光を被検者1の撮影領域に照準してX線可動絞り装置4でX線照射野を調整する。このX線照射野調整の終了を検出するX線照射野調整終了信号検出手段と、この検出手段で検出したX線照射野調整終了信号に対応して前記照射野ランプ3の点灯時間を制御する照射野ランプ点灯時間制御手段とを設けた。前記X線照射野調整終了信号検出手段は、X線撮影機構の機械的動作を検出する動作検出装置8を備え、前記照射野ランプ点灯時間制御手段は、前記機械的動作の終了信号で前記照射野ランプ3を消灯する照射野ランプ制御装置9を備えて構成される。【選択図】 図1
