<p>[PROBLEMS] To make it possible for an operator viewing a display body while grasping an operation handle to correctly obtain imaging-related information displayed on the display body regardless of the posture of an X-ray tube. [MEANS FOR SOLVING PROBLEMS] The X-ray tube holding device comprises a frame which is movable horizontally to the ceiling or the floor surface; a vertical shaft arranged in the vertical direction to the frame; a proximal portion rotatable about the axis line of the vertical shaft and movable up and down; an X-ray tube extending from the proximal portion side toward the distal end side on the distal end side in the radial direction with the proximal portion as a center, supported rotatably about a rotary shaft along the horizontal direction and equipped with an imaging section for irradiating X-rays toward a body to be photographed; and a display body for displaying the imaging-related information fixed to the further distal end side of the X-ray tube from the proximal portion, on the distal end side of the X-ray tube to be viewed by a facing operator facing the proximal portion side. The operator on the distal end side of the X-ray tube from the proximal portion can rotate the X-ray tube at least about the proximal portion or can move the X-ray tube horizontally to the ceiling or the floor surface, or can move the X-ray tube up and down to and from the ceiling or the floor surface, or can rotate the X-ray tube about the axis line of the vertical shaft. In such an X-ray tube holding device, a coupling body for mutually coupling the proximal portion and the display body is supported on the rotary shaft and arranged between the proximal portion and the display body to detour the X-ray tube arranged on the axis of the rotary shaft between the proximal portion and the display body so that the display body is not rotated about the rotary shaft in correspondence with the posture of the proximal portion even if the X-ray tube is rotated about the rotary shaft with respect to the proximal portion and the posture of the display body is maintained.</p> |
