A driving means for moving a detector in a C-arm includes a first frame including a first pulley, a motor connected to the first pulley, and a first belt stretched over the first pulley, a second frame for supporting the detector, and a third frame provided between the first frame and the second frame. Since the first belt and the third frame are connected to each other by a first connection member, a second pulley and a second belt stretched over the second pulley are mounted, and the second belt is connected to the first frame by a second connection member, an interval between an X-ray tube device and the detector for detecting X-ray becomes wider and a patient can be easily set at a photographing position. In addition, it is possible to lengthen a movement range of the detector to improve a freedom degree of photographing.
