PROBLEM TO BE SOLVED: To firmly connect a detector support part supporting a radiation detector and a turn shaft.SOLUTION: This radiographic apparatus includes: a rotary shaft, wherein both end parts in the axial direction are rotatably supported by the detector support part, a cutout part is formed in a part of the circumferential direction, and the other part of the circumferential direction is set as a non-formation part not formed with the cutout part a reception part fixed to the turn shaft, turning integrally with the turn shaft, and formed with a recessed part where the cutout part or the non-formation part is positioned thereinside when the detector support part is positioned in a prescribed turn position and a rotation drive part rotating the rotary shaft between a first rotation position where the non-formation part fits in the recessed part and the detector support part is connected with the turn shaft through the rotary shaft and the reception part to integrally turn, and a second rotation position where the cutout part is positioned inside the recessed part and where a connection state between the detector support part and the turn shaft is released.COPYRIGHT: (C)2013,JPO&INPIT【課題】放射線検出器を支持する検出器支持部と回動軸とを強固に連結できるようにする。【解決手段】軸方向両端部が検出器支持部に回転可能に支持され、周方向一部に切欠部が形成され、当該周方向の他の部分は当該切欠部が形成されていない非形成部とされた回転軸と、前記回動軸に固定されて前記回動軸と一体に回動し、前記検出器支持部が前記所定の回動位置に位置する場合において前記切欠部又は前記非形成部が内部に位置する凹部が形成された受け部と、前記非形成部が前記凹部に嵌合し、前記回転軸及び前記受け部を介して前記検出器支持部が前記回動軸と連結されて一体に回動可能な第1回転位置と、前記切欠部が前記凹部の内部に位置して前記検出器支持部と前記回動軸との連結状態が解除される第2回転位置とに、前記回転軸を回転させる回転駆動部と、を備える。【選択図】図4
