この磁気カードは、プラスチック製のカード本体ｌの表
面に磁性体材料を塗布した磁気記録領域である磁気スト
ライプ２を設け、この磁気ストライプ２に磁気を用いて
情報を記録するようになっている。また、カード本体１

度数表示位置に貫通孔３を形成することによってその度
数表示を行なうようになっている。This magnetic card has a magnetic stripe 2, which is a magnetic recording area coated with a magnetic material, on the surface of a plastic card body l, and information is recorded on the magnetic stripe 2 using magnetism. In addition, card body 1
It is possible to display the power used, and the power can be displayed by forming a through hole 3 at the position where the power used is displayed.
更に、カード本体ｌにカード本体ｌの表面につながる一
対の端子部４，４を設け、この端子部４．４間に複数の
抵抗層５，５・・・を接続するようにしている。Further, a pair of terminal portions 4, 4 connected to the surface of the card body 1 is provided on the card body 1, and a plurality of resistance layers 5, 5, . . . are connected between the terminal portions 4, 4.
抵抗層５，５・・・はカード本体１の内部に抵抗層とし
て形成してあり、外部から改ざん等の操作がなし得ない
ようになっている。また、各抵抗層５，５・・・は２個
の抵抗素子６，７を並列に接続した状態となっており、
各抵抗素子６，７は金属被膜抵抗素子又は絶縁金属基板
技術で使用されるカーボン抵抗素子にて形成し、薄形化
を図つている。尚、抵抗層のうち抵抗素子６，７以外の
部分は銅箔で形成するようにしている。The resistance layers 5, 5, . . . are formed as resistance layers inside the card body 1, and are designed to prevent manipulation such as tampering from the outside. Moreover, each resistance layer 5, 5... is in a state in which two resistance elements 6, 7 are connected in parallel,
Each resistor element 6, 7 is formed of a metal film resistor element or a carbon resistor element used in insulated metal substrate technology, and is designed to be thin. Note that the portions of the resistance layer other than the resistance elements 6 and 7 are made of copper foil.
更に、各抵抗層５，５・・・は一定の使用度数表示位置
と対応する位置に配してあり、かつ使用度数表示用の貫
通孔３形成位置に一方の抵抗素子７を位置させることに
より、使用度数表示用の貫通孔３によって抵抗素子７を
切断し得るようにしている。Furthermore, each of the resistive layers 5, 5... is arranged at a position corresponding to a certain number-of-use display position, and one of the resistive elements 7 is positioned at the position where the through hole 3 for displaying the number of use is formed. , the resistance element 7 can be cut by the through hole 3 for displaying the frequency of use.
そして更に、２つの抵抗素子６，７の抵抗値を異ならし
め、貫通孔３で切断する側の抵抗素子７の抵抗値を切断
しない側の抵抗素子６の抵抗値よりも十分低くし、貫通
孔３の数を抵抗値として容易に得ることができるように
し、しかも貫通孔３を何等かの物質で埋め合せたとして
も元にあった線状抵抗層と同一の抵抗値を持つ物でない
限りは判別し得るようにしている。Furthermore, the resistance values of the two resistance elements 6 and 7 are made different, and the resistance value of the resistance element 7 on the side to be cut by the through hole 3 is made sufficiently lower than the resistance value of the resistance element 6 on the side not to be cut. 3 can be easily obtained as a resistance value, and even if the through hole 3 is filled with some kind of substance, unless it has the same resistance value as the original linear resistance layer. I'm trying to make it easy to identify.
この状態を第３図及び第４図の３個の抵抗層５に例をと
って説明する。This state will be explained by taking three resistance layers 5 in FIGS. 3 and 4 as an example.
いま、貫通孔３で切断する側の各抵抗素子７の抵抗値を
ｒ（Ω）、切断しない側の各抵抗素子７の抵抗値をＲ［
Ｒ＝１０Ｏｒ（Ω）］とすると、第３図のように貫通孔
３で切断していない状態での端子部４，４間の全抵抗値
ｒｏ（Ω）は次のようになる。Now, the resistance value of each resistance element 7 on the side to be cut by the through hole 3 is r (Ω), and the resistance value of each resistance element 7 on the side not to be cut is R[
R=10Or(Ω)], the total resistance value ro(Ω) between the terminal portions 4, 4 in a state where they are not cut by the through hole 3 as shown in FIG. 3 is as follows.
ｒｏ ＝ （３００／１０１）ｒう３ｒ（Ω）次に、第
４図のように最初の抵抗層５の抵抗素子７を貫通孔３に
て切断すると、端子部４，４間の全抵抗値ｒ＋（Ω）は
次のようになる。ro = (300/101) r3r (Ω) Next, as shown in Fig. 4, when the resistance element 7 of the first resistance layer 5 is cut at the through hole 3, the total resistance value between the terminal parts 4, 4 is r+(Ω) is as follows.
ｒ＋ ＝ （１００＋２００／１０１）ｒキ１０２ｒ
（Ω）
以降、２番目、３番目の抵抗層５の抵抗素子７を順次貫
通孔３にて切断すると、切断の度に約１０ｏｒ抵抗値が
増加する。この全体抵抗値の変化により、度数の変化を
検出することができる。r+ = (100+200/101)rki102r
(Ω) Thereafter, when the resistive elements 7 of the second and third resistive layers 5 are sequentially cut through the through holes 3, the resistance value increases by about 10or each time. A change in power can be detected by this change in the overall resistance value.
もし、第４図の状態で貫通孔３に絶縁物質を詰め込んで
もｒｌ は変化しないので、度数を増やすような改ざん
は不可能である。Even if the through hole 3 is filled with an insulating material in the state shown in FIG. 4, rl will not change, so tampering to increase the frequency is impossible.
また、貫通孔３に導体を詰め込んで改ざんしようとした
場合には、端子部４，４間での抵抗値ｒ２は、
ｒ２＝ （０＋２００／ １０１） ｒ’＝２ ｒとな
って、ｒｌ との間に約１０Ｏｒの差が生じるため、
改ざんしたことを容易に判別できることとなる。In addition, if an attempt is made to tamper with the through hole 3 by stuffing a conductor into it, the resistance value r2 between the terminal parts 4 and 4 will be r2 = (0 + 200/ 101) r' = 2 r, and the difference between rl and Since there is a difference of about 10Or between
This makes it easy to determine that the information has been tampered with.
上記実施例においては２個の抵抗素子６，７を用いて各
抵抗層５を形成したが、これに限らず３個以上の抵抗素
子を用いることも可能である。In the above embodiment, each resistance layer 5 is formed using two resistance elements 6 and 7, but the present invention is not limited to this, and it is also possible to use three or more resistance elements.
また、抵抗素子６，７を抵抗値の異なるものを用いたが
抵抗値が同じものでも良い。ただし、実施例のように抵
抗値に大きな差を持たせれば、切断の際の全体抵抗値の
変化を大きくとることができる。Further, although resistance elements 6 and 7 having different resistance values are used, they may have the same resistance value. However, if the resistance values are made to have a large difference as in the embodiment, the overall resistance value can vary greatly during cutting.

。[Effects of the Invention] As explained above, the magnetic card of the present invention includes pairs of terminal portions provided on the card body, a plurality of resistive layers connected in series between the terminal portions, and each of the resistive layers is formed by connecting a plurality of resistance elements in parallel, and is arranged at a position corresponding to a certain number-of-use display position.The above-mentioned resistor element is arranged so that it can be cut by a through-hole for displaying the number-of-use, so it cannot be cut. By changing the resistance value of the entire resistance layer using the resistor element, it is possible to impart information properties, thereby making it possible to determine whether or not the stored information has been tampered with and to prevent the tampering.
また、第２項の発明は、更に加えて各抵抗層は抵抗値の
異なる複数種の抵抗素子を並列に接続すると共に、貫通
孔により切断される抵抗素子の抵抗値を他よりも小さく
したため、貫通孔を抵抗値として用い、たとえ貫通孔を
埋め込んでも容易に判別できることとなる。In addition, in the invention of item 2, each resistance layer has a plurality of types of resistance elements having different resistance values connected in parallel, and the resistance value of the resistance element cut by the through hole is made smaller than that of the others. By using the through hole as a resistance value, it can be easily determined even if the through hole is buried.
更に、第３項の発明は、抵抗素子として全屈被膜抵抗素
子又はカーボン抵抗素子を用いたため、改ざん防止機能
を持たせているにもかかわらず薄形化ができる。Furthermore, in the third aspect of the invention, since a full-flex film resistance element or a carbon resistance element is used as the resistance element, the structure can be made thinner even though it has a tamper-proofing function.
そして更に、第４項の発明は、カード本体の内部に複数
の抵抗層を形成したため、外部から抵抗層の存在が認識
できず、また抵抗層部分の不正操作も防止できることと
なる。Furthermore, in the fourth aspect of the invention, since a plurality of resistance layers are formed inside the card body, the presence of the resistance layers cannot be recognized from the outside, and unauthorized manipulation of the resistance layer portion can be prevented.
