摘要： Each of two X-ray sources hangs from a hook movably attached to a horizontal bar of a holding device. The horizontal bar is provided with a position indicating section that indicates positions suitable for each of the X-ray sources, corresponding to an object of interest (the size of X-ray irradiation area). The position indicating section has first to third lamps arranged at the respective suitable positions. Out of the first to third lamps, a holding device controller of an imaging control device turns on lamps corresponding to the object of interest inputted from an input device of a console. The hooks are moved along rails to the positions of the lamps turned on, respectively. Movable joints of support legs are operated to adjust a distance between the X-ray sources and an image receiving surface of a cassette.
