The X-ray tube and the film are supported by a link mechanism retaining the aforesaid positional relationship, and the above-mentioned movement is achieved by a control means. The control means comprises: a drive mechanism having an internal gear, and a planetary gear, in mesh with the internal gear, rotates itself and moves around the internal gear; and a control mechanism for controlling rotation of those gears.
