PROBLEM TO BE SOLVED: To easily execute general photography and laminagraphy by arranging a cut surface setting unit on the floor of a rear side part in a photography base, which is provided with a connection rod for connecting an X-ray tube held by means of a travelling type X-ray tube holder to a cassette holding body held in the lower part of the top plate of the photography base so as to be movable in a longitudinal direction. SOLUTION: When laminagraphy is executed, a connection rod 4 is inserted to a rocking core shaft 2 of a cut surface setting unit 20 and set and, then, the upper end of the rod 4 is connected to a horizontal arm 45 of the on-floor travelling type X-ray tube holder 40 by a connection bar 55. Besides, the lower end part of the rod 4 is connected to a cassette holder 34 by a connection bar 56. In this state, the holder 40 is moved along a rail 41 with a travelling truck 42. In this case, the laminagraphic image of a testee body is recorded on a film in the cassette holding body 34 by X-rays radiated from the tube 46. In the meantime, when general photography is executed, the connection of the holding body 34 and the holder 40 by the connection rod 4 is disconnected, the holder 40 is independently moved and the general photography is executed.
