［産業上の利用分野］
本考案は磁気シールド合せガラスに係り、特に
パチンコ等の遊戯機器の不正行為防止用のガラス
として有用な磁気シールド合せガラスに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetically shielding laminated glass, and particularly to a magnetically shielding laminated glass useful as a glass for preventing fraudulent activity in game machines such as pachinko.
［従来の技術］
近年、パチンコ等の遊戯機器に対して、前面ガ
ラスを破損させたり、磁石等の磁力を作用させて
不正行為をなす事件が多発している。[Prior Art] In recent years, there have been many incidents in which fraudulent activities are carried out on game machines such as pachinko by damaging the front glass or applying magnetic force such as a magnet.
このため、これらの遊戯機器の前面ガラスに
は、不正行為防止のために種々の対策がとられて
いる。例えば、破損や磁力防止等のために、前面
ガラスを空気層のある二重ガラスにしたり、電磁
波や磁石に対する警報標示システム等を接続した
りしている。 For this reason, various measures are taken on the front glass of these play machines to prevent fraudulent activities. For example, in order to prevent breakage and magnetism, the front glass is made of double-glazed glass with an air layer, and warning signs systems for electromagnetic waves and magnets are connected.
［考案が解決しようとする問題点］
しかしながら、空気層のある二重ガラスでは、
強力な磁力に対しては、厚い空気層が必要とな

いても、ライターの着火や携帯ラジオ等による電
磁波でパチンコのICコントロールが乱されるこ
とがある。[Problems that the invention aims to solve] However, double glazing with an air layer
Strong magnetic forces require a thick layer of air, and the gap between the two pieces of glass must be increased, which poses a problem in practical terms. Furthermore, there is almost no shielding function against electromagnetic waves themselves; for example, even if the front glass of a pachinko machine is double-glazed, the IC control of the pachinko machine may be disturbed by electromagnetic waves from a lighter being lit, a portable radio, etc.
一方、電磁波や磁石に対する警報標示システム
を採用した場合には、不正行為を確認して事故を
未然に防ぐことができるが、店内トラブル発生の
原因となるため、遊戯場においては適当な防止対
策とはいえない。 On the other hand, if a warning sign system against electromagnetic waves and magnets is adopted, it is possible to confirm fraudulent activities and prevent accidents, but since it can cause trouble in the store, appropriate preventive measures should be taken at the playground. No, no.
従つて、基本的に磁界、電界を確実に遮蔽する
ことができるガラスが要望されている。 Therefore, there is a need for a glass that can basically shield magnetic fields and electric fields reliably.

る。 Moreover, since this magnetic field absorbing material is in the form of a net, it can obtain an appropriate visible light transmittance, and the field of view will not be obstructed even when applied to the front glass of a game machine such as a pachinko machine. That is, magnetic materials such as metals that generally absorb magnetic fields are opaque materials. However, by coating this on an organic fiber net with an appropriate mesh,
Appropriate visible light transmittance can be obtained along with magnetic field absorption ability.
