PROBLEM TO BE SOLVED: To provide an X-ray fluoroscopic apparatus provided with a foot switch capable of reliably avoiding a switch stepping error without directing the line of sight toward the foot.SOLUTION: An X-ray fluoroscopic apparatus 1 includes a foot switch 29 to which a detection sensor 43 is provided. The detection sensor 43 detects whether or not an operators foot is in contact with a switch for each switch provided to the foot switch 29. Since the information detected by the detection sensor 43 is displayed on an image display monitor in a visible state such as by a character and video, the operator can visually confirm the information to specify the switch 39 that the foot is in contact with. Therefore, the operator can grasp the information on the switch 39 that is currently selected quickly and accurately.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT
