PROBLEM TO BE SOLVED: To perform radiographing by irradiation with X-rays vertically downwards in the area of the almost entire surface of a top plate and to perform radiographing from various angles other than that. SOLUTION: A rectangular frame body 24 is freely horizontally movably installed at the upper part of a bed 21, and the top plate 26 is provided on the frame body 24. At the lower part of the top plate 26, an X-ray image detector 27 is freely movably arranged. The X-ray image detector 27 is made freely horizontally movable to the frame body 24 by a carriage 30. The carriage 30 is composed of a tray 30a for detachably supporting the X-ray image detector 27 and a carriage lower part 30b, and the tray 30a and the carriage lower part 30b are fixed to each other and integrated at the time of normal radiographing. At the time of detaching the X-ray image detector 27, the tray 30a is moved to the carriage lower part 30b and the X-ray image detector 27 and the tray 30a are taken out from an opening part 33 to the outside of the frame body 24.
