PROBLEM TO BE SOLVED: To provide an open type magnetic shield structure with a door capable of obtaining sufficient magnetic shield effect in the entire internal space.SOLUTION: Band-like first C-shaped type magnetic plates 20z1, 20z2, ... ... surrounding a magnetic shield target space 1 with a door opening 11 and cut at the door opening 11 are provided on a plurality of parallel planes Pz1, Pz2, ... ... intersecting at a predetermined interval dz with a first direction shaft Az penetrating in parallel with a door 12 through the magnetic shield target space 1. Door magnetic plates 22 are provided in parallel with the first direction shaft Az on the door 12 closing the opening 11. Connection magnetic bodies 26z facing the door magnetic plates 22 and magnetically joined at the time of closing are attached to both ends of each cut part of the first C-shaped type magnetic plates 20z1, 20z2, ... .... Preferably, the door magnetic plates 22 are a plurality of band-like first I-shaped type magnetic plates 23z (23z1, 23z2, ... ...) mutually insulatedly provided along the intersection between the door 12 and the plurality of planes Pz1, Pz2, ... ... intersecting with the first direction shaft AZ.COPYRIGHT: (C)2014,JPO&INPIT【課題】内側空間の全体において十分な磁気シールド効果を得ることができる扉付き開放型磁気シールド構造を提供する。【解決手段】扉開口11付き磁気シールド対象空間1をその扉12と平行に貫く第1方向軸Azと所定間隔dzで交差する複数の平行な平面Pz1,Pz2,……上にそれぞれその空間1を囲みつつ扉開口11で切断された帯状の第1C字型磁性板20z1,20z2,……を設け,開口11を閉鎖する扉12上に第1方向軸Azと平行に扉磁性板22を設け,第1C字型磁性板20z1,20z2,……の各々の切断部分の両端に扉磁性板22と対向し且つ閉鎖時に磁気的に接合される繋ぎ磁性体26zを取り付ける。好ましくは,扉磁性板22を,第1方向軸Azと交差する複数の平面Pz1,Pz2,……と扉12との交線に沿ってそれぞれ相互に絶縁しつつ設けた複数の帯状の第1I字型磁性板23z(23z1,23z2,……)とする。【選択図】図1
