PURPOSE:To bring an intensifying film and a film closely into contact with each other uniformly while holding always the intensifying film in a stable shape, by interposing a cushion material, which is obtained by covering a plate-shaped porous elastic body with a highly airtight bag, between one plate body and the intensifying film. CONSTITUTION:A porous elastic body 31 formed into a relatively thick plate is covered with a highly airtight bag 32 and is sealed to constitute a cushion material 30, and its internal pressure is set to zero. In a film holder 1, two intensifying films 4 and 5 between which a film 6 is inserted are helf between plate bodies 2 and 3; and when the cushion material 30 is interposed between one plate body and intensifying films, the bag 32 receives the pressure of plate bodies 2 and 3 to bring the film 6 and intensifying films 4 and 5 closely into contact with each other uniformly. Since the free shape of the elastic body 31 is a plate shape, faces of the cushion material 30 on the intensifying film side are flat, and the cushion material and intensifying films are always held in stable shapes. |
