X-ray flux which has passed through the X-ray irradiation member for irradiating X-ray beam of a slit-like X-ray source from (11a) and (6) to (5) the object (10), subject (5) X-ray imaging apparatus, (6 X-ray imaging member provided light receiving surface which receives) is (7a) and (7), X-ray imaging member X-ray radiation member (10) and (7) around the 5 subjects turning center line (La) a rotation drive unit for causing pivoting movement about, auxiliary driving unit for causing the local motion different from the pivoting movement moving width in the circumferential direction (Mw) X-ray imaging member (7) and (30) provided. Width (7a) receiving surface in the circumferential direction (W2), less than (Mw) of the movement range, the local motion is the local rotational movement about a rotational axis (Lc). With this configuration, vibration reduction X-ray imaging member while allowing the cost reduction of X-ray imaging apparatus, due to the local motion (7), and improvement in the work efficiency of the X-ray imaging becomes possible. [Selection Figure Figure 3X線撮影装置は、被写体(5)にX線源(11a)からのスリット状のX線束(6)を照射するX線照射部材(10)と、被写体(5)を透過したX線束(6)を受光する受光面(7a)が設けられたX線撮像部材(7)と、X線照射部材(10)およびX線撮像部材(7)に被写体5の周りで旋回中心線(La)を中心とした旋回運動を行なわせる旋回駆動装置と、X線撮像部材(7)に周方向での移動幅(Mw)で前記旋回運動とは異なる局所運動を行わせる副駆動装置(30)とを備える。周方向での受光面(7a)の幅(W2)は、前記移動幅(Mw)よりも小さく、前記局所運動は、回転中心線(Lc)を中心とする局所回転運動である。この構成により、X線撮影装置のコスト削減を可能としながら、前記局所運動に起因するX線撮像部材(7)の振動の低減、およびX線撮影の作業効率の向上が可能になる。【選択図】図3
