【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、カード基材に形成された取付部に、ICモジ
ュールを埋設したICカードに関するものである。Description: TECHNICAL FIELD The present invention relates to an IC card in which an IC module is embedded in a mounting portion formed on a card base material.
〔従来の技術〕 第３図，第４図は、ICカードの従来例を示した図であ
る。[Prior Art] FIGS. 3 and 4 are views showing a conventional example of an IC card.
カード基材１には、取付部11が穿設されており、ICモ
ジュール２は、その取付部11に挿入され、接着剤等によ
り固定することにより、埋設されている（第３図
（ａ））。The card base 1 is provided with a mounting portion 11, and the IC module 2 is inserted into the mounting portion 11 and is buried by being fixed with an adhesive or the like (FIG. 3A). ).
このとき、取付部11とICモジュール２の大きさを比較
すると、取付部11の方を大きめに設計してある（第３図
（ｂ））。At this time, when comparing the sizes of the mounting portion 11 and the IC module 2, the mounting portion 11 is designed to be larger (FIG. 3 (b)).
しかし、前述した従来のICカードを製造する際に、 （ｉ）取付部11の加工寸法や、ICモジュール２の外形寸
法にバラツキがあり、 （ii）また、取付部11にICモジュール２を自動挿入する
場合に、その挿入位置にもバラツキがでる、 という問題があった。However, when manufacturing the above-described conventional IC card, there are variations in (i) the processing dimensions of the mounting portion 11 and the external dimensions of the IC module 2, and (ii) the IC module 2 is automatically mounted on the mounting portion 11. When inserting, there is a problem that the insertion position also varies.
このとき、取付部11とICモジュール２との寸法差が小
さいと、（ｉ），（ii）のバラツキ要素によって、挿入
時に、ICモジュール２がきれいに取付部11に入り切ら
ず、カード基材１やICモジュール２にキズを付けてしま
うなどの挿入不良が発生する可能性があった。At this time, if the dimensional difference between the mounting portion 11 and the IC module 2 is small, the IC module 2 does not enter the mounting portion 11 cleanly at the time of insertion due to the variation elements (i) and (ii). There is a possibility that an insertion failure such as scratching the IC module 2 or the IC module 2 may occur.
この問題を解決するために、取付部11をICモジュール
２に対して、十分に大きくすることも考えられるが（第
４図（ａ））、挿入不良がなくなる反面、取付部11とIC
モジュール２と隙間が大きくなるので、取付部11の中で
ICモジュール２が動いて、一方向に寄ってしまったり
（第４図（ｂ））、θ方向への回転によるズレが生ずる
という問題があった（第４図（ｃ））。In order to solve this problem, it is conceivable that the mounting portion 11 is made sufficiently large with respect to the IC module 2 (FIG. 4A).
Since the gap with the module 2 becomes large,
There has been a problem that the IC module 2 moves and shifts in one direction (FIG. 4 (b)), or a deviation occurs due to rotation in the θ direction (FIG. 4 (c)).
このとき、製造されたICカードが、製品として外観上
の見栄えが悪いばかりでなく、外部接続端子との位置精
度が悪くなり、信頼性が低下するという問題点があっ
た。At this time, the manufactured IC card not only has a poor appearance as a product, but also has a problem in that the positional accuracy with respect to the external connection terminal is deteriorated and the reliability is reduced.
本発明の目的は、取付部とICモジュールとの隙間を小
さくしても、ICモジュールを容易に挿入できるうえ、取
付位置精度がよく、しかも、挿入後に外観上の見栄えが
よいICカードを提供することである。An object of the present invention is to provide an IC card which can easily insert an IC module even if the gap between the mounting portion and the IC module is reduced, has a good mounting position accuracy, and has a good external appearance after insertion. That is.
前記課題を解決するために、本発明によるICカードの
第１の解決手段は、カード基材に形成された取付部に、
ICモジュールを埋設するICカードにおいて、前記取付部
の隅部分の半径を、前記ICモジュールの隅部分の半径よ
りも小さくする構成としてある。In order to solve the above-mentioned problem, a first solution of the IC card according to the present invention includes a mounting portion formed on a card base,
In the IC card in which the IC module is embedded, the radius of the corner of the mounting portion is smaller than the radius of the corner of the IC module.
また、第２の解決手段は、カード基材に形成された取
付部に、ICモジュールを埋設するICカードにおいて、前
記取付部と前記ICモジュールとの隅部分の寸法差を、辺
部分の寸法差よりも大きくした構成としてある。Further, a second solution means is that, in an IC card in which an IC module is embedded in a mounting portion formed on a card base material, a dimensional difference between a corner portion of the mounting portion and the IC module is reduced by a dimensional difference between side portions. There is a configuration that is larger than that.
前記構成によれば、挿入しずらい隅部分に余裕がで
き、取付部とICモジュールとの隙間が小さくても、挿入
作業が容易にできる。According to the above configuration, a margin can be provided in a corner portion where it is difficult to insert, and the insertion operation can be easily performed even if a gap between the mounting portion and the IC module is small.
以下、図面等を参照して、実施例につき、本発明を詳
細に説明する。Hereinafter, the present invention will be described in detail with reference to the drawings and the like based on embodiments.
第１図は、本発明によるICカードの第１の実施例を部
分的に示した図である。FIG. 1 is a diagram partially showing a first embodiment of an IC card according to the present invention.
なお、以下に説明する各実施例では、前述した従来例
と同様な機能を果たす部分には、同一の符号を付してあ
る。In each of the embodiments described below, the portions that perform the same functions as those of the above-described conventional example are denoted by the same reference numerals.
第１の実施例のICカードでは、取付部11の４つの隅部
分11aと半径が、ICモジュール２の隅部分2aの半径より
も小さくなるようにしてある。In the IC card of the first embodiment, the radius of the four corners 11a of the mounting portion 11 is smaller than the radius of the corner 2a of the IC module 2.
具体的には、取付部11の隅部分11aの半径を1.2mmと
し、ICモジュール２の隅部分2aの半径を1.5mmとしてあ
る。Specifically, the radius of the corner 11a of the mounting portion 11 is 1.2 mm, and the radius of the corner 2a of the IC module 2 is 1.5 mm.
このため、自動挿入装置を用いて、カード基材１の取
付部11にICモジュール２の挿入する場合に、入り難い隅
部分11aに余裕ができ、取付部11とICモジュール２との
寸法差を小さくしても、挿入不良が起こり難くなった。Therefore, when the IC module 2 is inserted into the mounting portion 11 of the card base material 1 by using the automatic insertion device, a margin is formed in the hardly accessible corner portion 11a, and the dimensional difference between the mounting portion 11 and the IC module 2 is reduced. Even if it was made smaller, poor insertion hardly occurred.
なお、ICモジュール２の製造時に、４つの辺部分が若
干凹状になっている場合が多いので、辺部分の中央で、
取付部11に引っ掛かることはなく、隅部分さえ余裕をも
って挿入されれば、挿入不良はなくなる。In addition, since the four sides are often slightly concave when the IC module 2 is manufactured, the center of the sides is
As long as it is not hooked on the mounting portion 11 and even the corner portion is inserted with a margin, the insertion failure is eliminated.
また、取付部11に対してICモジュール２がθ方向にず
れて挿入されようとした場合に、ICモジュール２が取付
部11から外れる面積が一番大きいのは４つの隅部分とな
る。従って、少なくとも４つの隅部分に、ICモジュール
２に対し取付部11に余裕を持たせておけば、外れる面積
が小さくなり、キズを付けることなく挿入することがで
きる。Also, when the IC module 2 is to be inserted into the mounting portion 11 with a shift in the θ direction, the four corners have the largest areas where the IC module 2 is detached from the mounting portion 11. Therefore, if the mounting portion 11 has a margin with respect to the IC module 2 in at least the four corner portions, the detached area becomes small, and the IC module 2 can be inserted without being damaged.
更に、隅部分に若干の隙間が残る程度で済み、外観上
も見栄えのよういICカードが製造できるようになった。Furthermore, only a small gap is left in the corner, and an IC card that looks good in appearance can be manufactured.
第２図は、本発明によるICカードの第２の実施例を部
分的に示した図である。FIG. 2 is a diagram partially showing a second embodiment of the IC card according to the present invention.
第２の実施例のICカードでは、取付部11とICモジュー
ル２との隅部分11bと隅部分2bの寸法差が、辺部分11cと
辺部分2cの寸法差よりも大きくなるようにしてある。In the IC card according to the second embodiment, the dimensional difference between the corner 11b and the corner 2b of the mounting portion 11 and the IC module 2 is larger than the dimensional difference between the side 11c and the side 2c.
具体的には、取付部11の隅部分11bの円弧の角度を90
度、ICモジュール２の隅部分2bの円弧の角度を120度と
してある。Specifically, the angle of the arc of the corner 11b of the mounting portion 11 is set to 90 degrees.
The angle of the arc of the corner 2b of the IC module 2 is set to 120 degrees.
この実施例でも、取付部11の隅部分1bに余裕ができ
る。Also in this embodiment, a margin can be provided in the corner portion 1b of the mounting portion 11.
なお、各実施例では、４つの隅部分について説明した
が、自動挿入装置の特性等を考慮して、１つの隅部分の
みに、本発明を適用するようにしてもよい。このとき、
１つの隅部分からのみ入りやくすることにより、ICモジ
ュールを逆に取り付けることを防止することができる。In each embodiment, four corners have been described. However, the present invention may be applied to only one corner in consideration of the characteristics of the automatic insertion device. At this time,
By making it easy to enter from only one corner, it is possible to prevent the IC module from being mounted in reverse.
また、隅部分に余裕をもたせるために、外観上の見栄
えが悪くならない範囲で、取付部の隅部分は直線を含む
形状にしてもよい。Further, in order to allow a margin in the corner portion, the corner portion of the mounting portion may have a shape including a straight line as long as the appearance is not deteriorated.
以上詳しく説明したように、本発明によれば、カード
基材の取付部とICモジュールの隅部分に余裕ができるの
で、取付部とICモジュールとの寸法差を小さくしても、
挿入不良が起こることがなくなった。As described in detail above, according to the present invention, a margin can be provided between the mounting portion of the card base material and the corner of the IC module, so that the dimensional difference between the mounting portion and the IC module can be reduced.
Improper insertion no longer occurs.
また、隅部分に若干の隙間が残る程度で済み、外観上
の見栄えもよくなった。Also, only a small gap was left in the corner, and the appearance was improved.
