To allow a patient to eliminate labor and time to get down from an examination chair and to move to a radiographic room in X-ray photography.

A radiation protective wall 2 is arranged at least on one surface of a mobil cabinet 1, and a freely horizontally openable rotary door 6 is arranged in one surface of the radiation protective room 5 which is enclosed by the radiation protective walls 3. Then, the rotary door 6 is closed, thereby reducing the radiation protective room 5. The surface of the radiation protective wall 2 in the cabinet 1 is abutted onto the closed surface, and moreover, the plurality of other mobile cabinets are made to come close to the radiation protective room 5. Thus, a multi-purpose space is formed in the medical examination room. When the rotary door 6 of the radiation protective room 5 is opened and the radiation protective wall 2 arranged in the mobile cabinet 1 is abutted onto the open end part of the door 6, the radiation protective room 5 is extended. When the plurality of other mobile cabinets are moved to obtain a desired interval, a multi-purpose area is formed.
