PROBLEM TO BE SOLVED: To expand a photographic region by reserving enough moving area of a top plate and moving area of a radiographic imaging part as well as to increase the efficiency in a positioning work performed by an engineer when photographing.SOLUTION: The device comprises the top plate 14 on which an examinee P is placed, the radiographic imaging part 15 for detecting radiation transmitted through the examinee P under the top plate 14, a laterally moving mechanism 21 for supporting the top plate 14 as well as moving the top plate 14 in the lateral direction, a frame 25 for supporting the laterally moving mechanism 21 as well as supporting the radiographic imaging part 15 to enable the imaging part 15 to move in the longitudinal direction of the top plate 14, a longitudinally moving unit 22 for supporting the frame 25 and moving the frame 25 in the longitudinal direction of the top plate 14, and a base part 12 for supporting the longitudinally moving unit 22.COPYRIGHT: (C)2012,JPO&INPIT【課題】天板の移動範囲及び放射線撮像部の移動範囲をそれぞれ十分に確保して撮影領域を広げると共に、撮影に際し技師が行う位置合わせ作業の効率化を図る。【解決手段】被検者Pを載置する天板14と、被検者Pを透過した放射線を天板14の下方で検出する放射線撮像部15と、天板14を支持すると共に天板14を短手方向に移動させる短手方向移動機構21と、この短手方向移動機構21を支持すると共に放射線撮像部15を天板14の長手方向に移動可能に支持するフレーム25と、フレーム25を支持すると共にフレーム25を天板14の長手方向に移動させる長手方向移動手段22と、長手方向移動手段22を支持する基台部12とから構成する。【選択図】 図1
