Abstract
PURPOSE:To shield a room from an electromagnetic wave and automate a means to carry equipments and materials out and in the room, shielding a doorway of the shielded room from an electromagnetic wave by a method wherein a doorway is automatically opened and shut with an electromagnetically shielding material which moves up and down by an up-and-down device and a peripheral end of the electrically shielding material is made to bear against a fixed frame by a movable frame. CONSTITUTION:A shutter open-and-shut device 19, which opens and shuts automatically, pulls up and down a shielding screen 17 so as to open and shut a doorway 3 when equipments and materials are carried out and in. A floor of the doorway is flat and provided with only a slot in which a shielding screen 17 is fitted. When the shielding screen 17 descends between a fixed frame 5 and a movable frame 29 so as to shut the doorway 3, a jack 35 is remotely controlled to transfer a supporting arm 27 in a direction of an arrow A, making the movable frame 29 bear against the fixed frame 5, so that a peripheral end of the shielding serene 17 is held between the movable frame 29 and the fixed frame 5, and the fixed frame 5 is electrically combined with the shielding screen 17 into one piece.
