Provided is a ceiling-suspended X-ray imaging apparatus that can reliably move the distal end portion of an X-ray movable diaphragm to a desired position in an easy posture without forcing an operator into an unreasonable posture. The ceiling-suspended X-ray imaging apparatus 1 includes an X-ray tube provided with a head unit 100 and an X-ray movable diaphragm 102 having an X-ray irradiation axis Q orthogonal to a first rotation axis 81 that rotates the head unit 100. An apparatus 101, an operation panel 101 disposed in front of the X-ray tube apparatus 101, an annular base handle 120c that is provided so as to surround the operation panel 101c and that is open, and an open end The operation handle 130c is arranged between the first rotation shaft 81 and the second rotation shaft 131 which is disposed in parallel with the first rotation shaft 81 and with a predetermined distance d2. The operation panel 110c and the operation handle 130c are provided with a lock release switch 132 that is rotatably attached to the X-ray tube apparatus 101 and that releases the lock state of the plurality of lock mechanisms.操作者に無理な姿勢を強いることなく、Ｘ線可動絞りの先端部を所望の位置に楽な姿勢で確実に移動できる天井懸垂式のＸ線撮像装置を提供する。天井懸垂式のＸ線撮像装置１は、ヘッド部１００と、このヘッド部１００を回転させる第１回転軸８１と直交するＸ線照射軸Ｑを備えたＸ線可動絞り１０２を設けたＸ線管装置１０１と、このＸ線管装置１０１の前面に配置され操作パネル１０１と、この操作パネル１０１ｃの周囲を囲むように設けられる一方が開放される環状のベースハンドル１２０ｃと、この開放される端部との間に配置される操作ハンドル１３０ｃとを含んで構成され、操作ハンドル１３０ｃは、第１回転軸８１と平行で、かつ所定の間隔ｄ２を持って配置される第２回転軸１３１を介してＸ線管装置１０１に回転可能に取り付けられ、複数のロック機構部のロック状態を解除するロック解除スイッチ１３２を操作パネル１１０ｃと操作ハンドル１３０ｃに設けている。
