ELECTROMAGNETIC WAVE SHIELD BOX

PROBLEM TO BE SOLVED: To secure a visibility and an air permeability of an accomodating equipment and to surely demonstarte a function for shielding an electromagnetic wave without increasing the type of component. SOLUTION: A plurality of conductive supporting columns 12 are erected on a conductive base plate, and a plurality of conductive crosspieces are hung between the columns to compose a skeleton structure 14. A conductive door 16 releasably shuts an opening part 14a for the door out of the opening part of a periphery surface of the bone structure, a conductive wall member 17 shuts an opening part 14b of a periphery surface of the bone structure except an opening part for the door, and a conductive ceiling member shuts an opening part of an upper surface of the bone structure. The door has a frame 16a for the conductive door, and a net 16b for the conductive door with its periphery edge fixed to the frame for the door. The wall member has a frame 17a for the conductive wall and a net 17b for the conductive wall with its periphery edge fixed to the frame for the wall. The ceiling member has a frame for the conductive ceiling and a net for the conductive ceiling with its periphery edge fixed to the frame for the ceiling. COPYRIGHT: (C)2005,JPO&NCIPI
