PROBLEM TO BE SOLVED: To provide an X-ray diagnostic device which limits abrupt movement of an object to be moved when using a second detector and improves operability of the object to be moved by an operator.SOLUTION: An X-ray diagnostic apparatus 1 includes: a mechanical part 4 moving objects to be moved indicating a detector, a placing part and a support part an operation part 10 operating movement of the objects to be moved and a system control part 13 controlling the mechanical part 4 so as to change a moving amount relative to an operation amount from an operation part in response to a view size of the detector when movement of at least one of the objects to be moved is operated by the operation part 10.COPYRIGHT: (C)2015,JPO&INPIT【課題】X線診断装置において、第2検出器使用時における被移動体の急激な移動を制限し、操作者による被移動体の操作性を向上させること。【解決手段】X線診断装置1は、検出器、載置部、及び支持部を示す被移動体を移動させる機構部4と、被移動体の移動を操作する操作部10と、操作部10によって被移動体の少なくとも1の移動が操作されると、検出器の視野サイズに応じて操作部からの操作量に対する移動量を変更するように機構部4を制御するシステム制御部13と、を有する。【選択図】 図6
