Description

【0001】
【発明の属する技術分野】
本発明は、外部機器との間でデータの読み書きとその処理を行うICチップと外部機器との接点機構及び結合機構とを一体にしてモジュール化したICチップモジュール並びにICカードに関する。
【0002】
【従来の技術】
一般に使用されるICカードは、自動認識、セキュリティー等の目的で使用されている。従来のICカードとしては、本出願人が先に提示した(特公昭53−6491号公報)に記載されているようなものがある。この従来のICカードは、例えばクレジットカードや身分証明書等のプラスチックカード本体にメモリやCPU(中央演算処理装置)の機能を有するIC(集積回路)を備えたものである。
【0003】
このようなICカードは、電気的接点を介して接続した外部機器からの入力を能動素子によって処理した上で新たな信号として出力することにより、照合や信号の授受を自動的に確実に行うことができ、クレジットカードや銀行カード、デビッドカード、健康カード等に利用され、記憶量、情報量の大きさや記憶情報の秘密性・融通性に優れ、偽造の恐れも極めて少ない。
【0004】
しかし入出力の授受は電気的接点を介してカードリーダ等の外部機器との接触により行うものであるから、例えば出退勤の入退室管理に用いた場合に、カードの携帯者の操作が煩雑になることは止むを得ない。
【0005】
また本出願人の提示済みの「アクティブ素子による判別装置」(特開昭51−12799号公報)等による非接触方式の応答器に係るものがある。このような非接触方式はスピード性や融通性、簡便性に優れ、アクセスコントロール、定期券、高速道路券、移動体識別やベンディングマシン等種々の支払いに利用されている。即ちカードの携帯者がカードをセンサーに近づけるだけで、あるいはゲートに近づいたりするだけでカード情報のやり取りが行われるので、カードをリーダに挿入する手間が省ける。
【0006】
またこのような両者の機能を合い備え一枚のカードに具現化させることにより、両方の特徴が一度に得られるようにした本出願人による「複合ICカード」(特公平4−16831号公報)にも詳細に記述されている。
【0007】
【発明が解決しようとする課題】
しかし、ICカードにより、接触式と非接触式の両方式の特徴が具現化された場合でも、接触端子の部分とコイルの部分とが別々に設計されたり配置されているため、カードの中に接触端子やコイルを配置するためのスペースを作ったり、個々の作業を行うため高価となるという問題がある。さらにICチップを両方式で共有する場合でも、接触端子のみならずコイル等にも配線しなければならないので、このための作業にも余分な手間がかかるという問題がある。
【0008】
以上のような問題を解決するために本発明では、接触式と非接触式の機能を一枚のカードに具現化させるため、ICチップを含めた端子部とコイルやアンテナ部を一体にしてモジュール化し、カードに実装して接触、非接触の両機能を持つ安価で作り易い構造のICチップモジュール並びにICカードを提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するため、請求項1に記載の発明は、メモリを少なくとも含みCPUや外部の機器に応答して信号の送受を行うインターフェース部を有するICチップと、第1の外部装置と電気的に応答するための接点機構と、前記第1の外部装置又は第2の外部装置と非接触で応答するための結合機構とを一体にしてモジュール化したことを特徴とする。
【0010】
請求項2に記載の発明は、前記接点機構と前記結合機構との間に前記ICチップを挟み込み一体にしてモジュール化したことを特徴とする。
請求項3に記載の発明は、前記接点機構と前記結合機構と前記ICチップとを同一基板上に配設し一体にしてモジュール化したことを特徴とする。
請求項4に記載の発明は、前記接点機構の外側に前記結合機構を配設し一体にしてモジュール化したことを特徴とする。
【0011】
請求項5に記載の発明は、請求項1〜4のいずれか1項に記載のICチップモジュールを用い、キャッシュカード、クレジットカード等のカード形態に構成したことを特徴とする。
【0012】
【発明の実施の形態】
次に本発明にかかるICチップモジュールを実装したICカードの、実施の形態の具体例を、図を参照して説明する。
図1は、本発明の、第1の実施の形態によるICチップモジュールを実装したICカードの斜視図である。
図1(a)はICカードの表面側、図1(b)はその裏側をそれぞれ示している。符号1はICカードの本体を示し、一般のICカードに適用されている規格に適合するサイズと形状を有するもので、ICカード1の内部には、第1の外部装置と応答するための接点機構と、第1の外部装置又は第2の外部装置と非接触で応答するための結合機構と、ICチップとを一体化したICチップモジュールが実装されている。表面には接点機構をなす接触端子2が、裏面には非接触で応答するための結合機構をなす結合コイル3が配設されている。両面基板又は多層の積層基板を用いた場合には上面にコイルが現れなくても裏側(または中側)にコイルを配置してもよい。
【0013】
一般の接触式ICカードは、6端子又は8端子の四角形に配置されたものが標準となった接触部を有するため、接触部を有する基板の部分と更にその奥にチップが入る部分に2段に凹部ができており、最初から抜き型で加工したものもあるが、通常はこの凹部を機械で切削加工している。機械加工で作る場合は、円形に加工するほうがかなり容易である。即ち一番目の凹部を円形にして二段目の凹部も円形にしたならばそのような形の切削バイトを用いて一回で加工できる。四角いチップを埋め込む部分も円形に切削し、図2に示すようなICチップ4を保護するプラスチック7を設ければよい。このような構成にすることで皿状の凹部を円形にし、表側に出る孔をモジュールに合わせて四角として打ち抜きとすることも可能である。
【0014】

カード本体1の表面とほぼ同じ高さに接触端子2が配設されている。接触端子2は、一般にフィルムキャリアまたはフレキシブル基板で構成される基板5に配置され両面に金属箔があり、一方は外部接続用で他方はチップ配線用となっている。ICチップ4が接触端子2の裏側に取付けられており、その下側の基板6に非接触用のコイル3が配置されている。コイル3は基板6をエッチングして渦巻状パターンのコイルとしたもので、コイルの2個の端子をICチップ4に直接接続するか上方の端子の基板に接続するかはICチップ4の向きと、ICチップ4と基板のボンディング方法や接続方法等に依存する。ICチップ4にはICチップ4を保護するプラスチック7で固められモジュール化がされている。
【0015】
図3は、図2に示したICチップモジュールの断面図である。
図3(a)に示すようにICチップモジュールは接触端子2が形成された基板5、ICチップ4と対向する面に非接触用のコイル3が形成された基板部6とから成り立っている。ICカードとして構成する場合は、このようなモジュールをカードに嵌め込み、コイル基板6とICチップ4を保護するプラスチック7の側面に接着剤を塗布してカード本体に接着すればよい。
図3(b)、図3(c)は、図3(a)の変形で、図3(b)は非接触用のコイル3aをICチップ4が載る基板6の面と同一の面に形成し、ICチップ4の周辺を囲うように配置したものであり、図3(c)はコイル3及びコイル3aを基板6の両面に配置して接続し、二重螺旋構造としたものである。
【0016】
図4は、本発明の、第2の実施の形態によるICチップモジュールを実装したICカードの斜視図である。
接触端子2と非接触用のコイル3を同一の基板上に構成したICチップモジュールを、カード本体1に埋め込んである。接触端子2の外側(周囲)にコイルが配置されている。
【0017】
図5は、図4に示したICカードにICチップモジュールを実装した断面図である。
接触端子2は基板5の上面に配置されていなければならないが、非接触用のコイル3は上面でなくてもICチップ4を搭載する基板面、すなわち下面に配置してもよい。いずれも端子と接触しないように構成すればよい。
【0018】
図6は、図5に示したICチップモジュールの断面図である。
図6(a)では接触端子2を囲うように非接触用のコイル3が基板5上に配置されており、この基板5の裏側にICチップ4が取付けられ、さらに、ICチップ4を保護するプラスティク7で固めてモジュール化がされている。
図6(b)、図6(c)は、図6(a)を変形したもので、図6(b)は非接触用のコイル3aをICチップ4が載る基板面と同一の面に形成し、ICチップ4の周辺を囲うように配置したものであり、図6(c)はコイル3及びコイル3aを基板6の両面に配置して接続し、二重螺旋構造としたものである。
【0019】
図7は、図6に示したICチップモジュールの斜視図である。

【0021】
【発明の効果】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an IC chip module and an IC card in which an IC chip for reading / writing data from / to an external device and a processing thereof are integrated with a contact mechanism and a coupling mechanism between the external device and a module.
[0002]
[Prior art]
A commonly used IC card is used for purposes such as automatic recognition and security. 2. Description of the Related Art As a conventional IC card, there is one described in Japanese Patent Publication No. 53-6491 presented earlier by the present applicant. This conventional IC card includes a plastic card body such as a credit card or an identification card, and an IC (integrated circuit) having a memory and a CPU (central processing unit) function.
[0003]
Such an IC card automatically and surely performs collation and signal transmission and reception by processing an input from an external device connected via an electrical contact by an active element and outputting it as a new signal. It is used for credit cards, bank cards, debit cards, health cards, etc., and has excellent storage capacity, large amount of information, confidentiality and flexibility of stored information, and extremely low risk of forgery.
[0004]
However, since input / output is performed by contact with an external device such as a card reader through an electrical contact, for example, when used for entry / exit management of attendance, the operation of the card carrier becomes complicated. It is unavoidable.
[0005]
There is also a non-contact type transponder according to the "identification device using an active element" (JP-A-51-12799) presented by the present applicant. Such a non-contact method is excellent in speed, flexibility, and simplicity, and is used for various payments such as access control, commuter pass, highway ticket, moving object identification, and bending machine. That is, since the card information is exchanged only by the card carrier bringing the card close to the sensor or the gate, the trouble of inserting the card into the reader can be saved.
[0006]
A "combined IC card" (Japanese Patent Publication No. 16831/1992) by the applicant of the present invention, in which both functions are combined and embodied in one card so that both characteristics can be obtained at once. Is also described in detail.
[0007]
[Problems to be solved by the invention]
However, even when the characteristics of both the contact type and the non-contact type are realized by the IC card, since the contact terminal portion and the coil portion are separately designed and arranged, the card is not included in the card. There is a problem that a space for arranging the contact terminals and the coil is created, and that it is expensive because individual work is performed. Furthermore, even when the IC chip is shared by both types, wiring must be performed not only on the contact terminals but also on the coil and the like, so that there is a problem that extra work is required for this operation.
[0008]
In order to solve the above-mentioned problems, in the present invention, in order to embody the contact type and non-contact type functions on one card, a module including an IC chip and a coil and an antenna are integrated. It is an object of the present invention to provide an inexpensive and easy-to-manufacture IC chip module and an IC card having both contact and non-contact functions mounted on a card.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 includes an IC chip including at least a memory and having an interface unit for transmitting / receiving a signal in response to a CPU or an external device, and electrically connecting the first external device to the IC chip. And a coupling mechanism for responding to the first external device or the second external device in a non-contact manner.
[0010]
The invention according to claim 2 is characterized in that the IC chip is sandwiched between the contact mechanism and the coupling mechanism to be integrated into a module.
The invention according to claim 3 is characterized in that the contact mechanism, the coupling mechanism, and the IC chip are provided on the same substrate and integrated into a module.
The invention described in claim 4 is characterized in that the coupling mechanism is provided outside the contact mechanism and is integrated into a module.
[0011]
A fifth aspect of the present invention is characterized in that the IC chip module according to any one of the first to fourth aspects is used in a card form such as a cash card or a credit card.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a specific example of an embodiment of an IC card on which an IC chip module according to the present invention is mounted will be described with reference to the drawings.
FIG. 1 is a perspective view of an IC card mounted with an IC chip module according to a first embodiment of the present invention.
FIG. 1A shows the front side of the IC card, and FIG. 1B shows the back side thereof. Reference numeral 1 denotes a main body of the IC card, which has a size and a shape conforming to a standard applied to a general IC card, and has a contact inside the IC card 1 for responding to a first external device. An IC chip module in which a mechanism, a coupling mechanism for responding to the first external device or the second external device in a non-contact manner, and an IC chip are mounted. A contact terminal 2 serving as a contact mechanism is provided on the front surface, and a coupling coil 3 serving as a coupling mechanism for non-contact response is provided on the rear surface. When a double-sided substrate or a multilayer laminated substrate is used, the coil may be arranged on the back side (or the middle side) even if the coil does not appear on the upper surface.
[0013]
A general contact type IC card has a standard contact portion which is arranged in a 6-terminal or 8-terminal rectangular shape. Therefore, two stages are provided at a portion of the substrate having the contact portion and at a portion further into which the chip enters. A concave portion is formed in the concave portion, and some of the concave portions are processed by a punching die from the beginning, but usually, the concave portion is machined. If it is made by machining, it is much easier to make it circular. That is, if the first concave portion is made circular and the second concave portion is also made circular, it can be processed at one time using a cutting tool having such a shape. The portion in which the square chip is embedded may be cut into a circle, and a plastic 7 for protecting the IC chip 4 as shown in FIG. 2 may be provided. With such a configuration, it is also possible to make the dish-shaped concave portion circular, and to form a hole on the front side as a square according to the module and punch it out.

Contact terminals 2 are arranged at substantially the same height as the surface of the card body 1. The contact terminals 2 are disposed on a substrate 5 generally formed of a film carrier or a flexible substrate, and have metal foils on both sides, one for external connection and the other for chip wiring. An IC chip 4 is attached to the back side of the contact terminal 2, and a non-contact coil 3 is arranged on a substrate 6 below the contact terminal 2. The coil 3 is obtained by etching the substrate 6 into a coil having a spiral pattern. Whether the two terminals of the coil are directly connected to the IC chip 4 or connected to the substrate of the upper terminal depends on the direction of the IC chip 4. And the bonding method and connection method between the IC chip 4 and the substrate. The IC chip 4 is modularized by being hardened with a plastic 7 for protecting the IC chip 4.
[0015]
FIG. 3 is a sectional view of the IC chip module shown in FIG.
As shown in FIG. 3A, the IC chip module includes a substrate 5 on which contact terminals 2 are formed, and a substrate portion 6 on which a non-contact coil 3 is formed on a surface facing the IC chip 4. When configured as an IC card, such a module may be fitted into the card, and an adhesive may be applied to the side surface of the plastic 7 that protects the coil substrate 6 and the IC chip 4 and adhered to the card body.

[0017]
FIG. 5 is a cross-sectional view in which an IC chip module is mounted on the IC card shown in FIG.
The contact terminals 2 must be arranged on the upper surface of the substrate 5, but the non-contact coil 3 may be arranged not on the upper surface but on the substrate surface on which the IC chip 4 is mounted, that is, on the lower surface. What is necessary is just to comprise so that neither may contact a terminal.
[0018]
FIG. 6 is a sectional view of the IC chip module shown in FIG.
In FIG. 6A, a non-contact coil 3 is arranged on a substrate 5 so as to surround the contact terminal 2, and an IC chip 4 is mounted on the back side of the substrate 5 to further protect the IC chip 4. Modularized by plastic 7
6 (b) and 6 (c) are modifications of FIG. 6 (a), and FIG. 6 (b) shows a non-contact coil 3a formed on the same surface as the substrate surface on which the IC chip 4 is mounted. In FIG. 6C, the coil 3 and the coil 3a are arranged and connected on both sides of the substrate 6 to form a double spiral structure.
[0019]
FIG. 7 is a perspective view of the IC chip module shown in FIG.
7A is a perspective view when the coil 3 is circular, and FIG. 7B is a perspective view when the coil 3 is rectangular.
[0020]
