Patent ID: 8449183

Claim:
An X-ray tube holding apparatus comprising: a mount configured to be translated with respect to a ceiling or a floor surface; a vertical shaft arranged in a vertical direction with respect to the mount; a base unit configured to swivel on an axial line of the vertical shaft and move up and down; an X-ray tube that is provided on a distal end in an irradiating direction with the base unit, the base unit being axially supported to allow swiveling motion on a swiveling shaft along a horizontal direction, and the base unit including an imaging unit for supplying an X-ray from the X-ray tube toward a photography subject; a display body disposed distanced from the X-ray tube with respect to the base unit, provided on a distal end of the X-ray tube, enables visual recognition when facing an operator who is directed to the base unit, and displays imaging relevant information, the X-ray tube being configured to be swiveled with respect to at least the base unit, translated with respect to the ceiling or the floor surface, moved up and down with respect to the ceiling or the floor surface, or swiveled on the axial line of the vertical shaft by the operator at the distal end of the X-ray tube, wherein an X-ray tube holding apparatus including a coupling body that is axially supported on the swiveling shaft between the base unit and the display body, arranged between the base unit and the display body so as to bypass the X-ray tube arranged on the axial line of the swiveling shaft between the base unit and the display body, and enables coupling the base unit with the display body so as to maintain a posture of the display body even in a state that the display body is coupled with the base unit and the X-ray tube is swiveled on the swiveling shaft with respect to the base unit without swiveling the display body on the swiveling shaft in accordance with a posture of the base unit; and a coupling arm of the coupling body extending to the display body from the base unit toward the display body for enabling coupling of the base unit with the display body, a proximal end of the coupling arm being supported on the base unit, and the display body being supported on a distal end of the coupling arm in a fixed state.
