Translated fromJapanese

この発明は、例えば情報を記憶して非接触で通信するような非接触IC媒体、に関する。  The present invention relates to a non-contact IC medium that stores information and communicates in a non-contact manner, for example.

一般に、個人を識別して金銭を電子的に取り扱う情報記憶媒体として、キャッシュカードやクレジットカード、デビットカードなどが利用されている。このようなカードには、個人を識別するIDや、チャージされている金額などの情報を記憶する情報記憶媒体として磁気ストライプが備えられ、該磁気ストライプに記憶した情報に基づいて取引が行われる。  Generally, a cash card, a credit card, a debit card, or the like is used as an information storage medium that identifies an individual and handles money electronically. Such a card is provided with a magnetic stripe as an information storage medium for storing information such as an ID for identifying an individual and a charged amount, and a transaction is performed based on information stored in the magnetic stripe.

近年、このような情報記憶媒体として、非接触で通信できる非接触IC媒体が提供されている。この非接触IC媒体は、ICチップ内に制御部と記憶部を備え、このICチップにアンテナが接続されたものであり、アンテナによる非接触通信で情報を送受信することができる。  In recent years, non-contact IC media capable of non-contact communication have been provided as such information storage media. The non-contact IC medium includes a control unit and a storage unit in an IC chip, and an antenna is connected to the IC chip. Information can be transmitted and received by non-contact communication using the antenna.

この非接触IC媒体は、ドアのロックを開閉する開閉キーとして使用する場合であれば0.8MHzの通信周波数が使用され、ETCであれば125kHzの通信周波数が使用され、鉄道の自動改札機の通過用であれば13.56MHzの通信周波数が使用されるといったように、様々な種類のものが利用されている。  This non-contact IC medium uses a communication frequency of 0.8 MHz when used as an opening / closing key for opening and closing a door lock, and a communication frequency of 125 kHz is used for an ETC. Various types are used such as a communication frequency of 13.56 MHz is used for passing.

一方、複数の周波数に対して通信できるように、共振周波数の異なる複数のアンテナを備えたRF−ID用アンテナが提案されている(特許文献1参照)。
このRF−ID用アンテナによれば、ICチップにて情報の読み書きが可能な複数の周波数のうち任意の周波数に共振できるとされている。
On the other hand, an RF-ID antenna including a plurality of antennas having different resonance frequencies has been proposed so that communication can be performed with respect to a plurality of frequencies (see Patent Document 1).
According to this RF-ID antenna, it can resonate at an arbitrary frequency among a plurality of frequencies at which information can be read and written by the IC chip.

しかし、ICチップはひとつであるため、記憶できる情報量は変わらず、上述した複数の用途に対応するものとしては適していなかった。  However, since there is only one IC chip, the amount of information that can be stored does not change, and it is not suitable for a plurality of uses described above.

スペーサ部材11は、第2ラミネート部材15と同一サイズで肉厚一定の平面形状に形成されている。スペーサ部材11の短手方向中央には、前記接点24,24の位置を囲繞するように長方形のスライド用穴12が設けられている。このスライド用穴12における左右の長手辺は平行な一直線状のスライドガイド13,13を構成している。  Thespacer member 11 has the same size as thesecond laminate member 15 and is formed in a planar shape with a constant thickness. Arectangular slide hole 12 is provided at the center of thespacer member 11 in the short direction so as to surround the position of thecontacts 24, 24. The left and right longitudinal sides of theslide hole 12 constitute parallelstraight slide guides 13 and 13.

スペーサ部材11のスライド用穴12内には、切替部5が収納される。この切替部5は、板状部材6と操作部7とICチップ21a,21bと接点20a,20bとで構成されている。  Theswitching unit 5 is accommodated in theslide hole 12 of thespacer member 11. Theswitching unit 5 includes a plate-like member 6, anoperation unit 7,IC chips 21a and 21b, andcontacts 20a and 20b.

板状部材6は、スライド用穴12の左右幅と同一か僅かに小さい横幅で、スライド用穴12の縦幅より短い縦幅の長方形であり、肉厚一定の平面形状に形成されている。この板状部材6の両側辺8,8は、互いに平行で一直線状に形成されている。  The plate-like member 6 is a rectangle having a horizontal width that is the same as or slightly smaller than the horizontal width of theslide hole 12 and is shorter than the vertical width of theslide hole 12, and is formed in a planar shape having a constant thickness. Both side edges 8, 8 of the plate-like member 6 are formed in parallel and in a straight line.

操作部7は、板状部材6の縦方向の一端で幅方向中央に表面側(第1ラミネート部材2側)に突出形成され、その表面は滑り止め加工がなされている。  Theoperation unit 7 is formed so as to protrude to the surface side (first laminate member 2 side) at the center in the width direction at one end in the longitudinal direction of the plate-like member 6, and the surface is anti-slip processed.

ICチップ21a,21bは、板状部材6の裏面側(第2ラミネート部材15側)に、前後方向に並べて接着固定されており、該ICチップ21a,21bの端子が、それぞれ接点20a,20bに電気的に接続されている。この接点20a,20bは、板状部材6の裏面側に接着固定されており、裏面側へ突出している。接点20aと接点20bは、前後方向に一定間隔を隔てて一直線に配設されており、接点20aと接点20bの間には電気回路が存在しないように構成されている。  TheIC chips 21a and 21b are bonded and fixed side by side in the front-rear direction on the back side (second laminate member 15 side) of the plate-like member 6, and the terminals of theIC chips 21a and 21b are respectively connected to thecontacts 20a and 20b. Electrically connected. Thecontacts 20a and 20b are bonded and fixed to the back side of the plate-like member 6 and protrude to the back side. Thecontact 20a and thecontact 20b are arranged in a straight line with a predetermined interval in the front-rear direction, and are configured such that no electric circuit exists between thecontact 20a and thecontact 20b.

このように構成された切替部5は、スペーサ部材11のスライド用穴12内で、側辺8,8がスライドガイド13,13に沿って安定して前後方向にスライド移動できる。  Theswitching portion 5 configured as described above can stably slide and move the side edges 8 and 8 along theslide guides 13 and 13 in theslide hole 12 of thespacer member 11.

第1ラミネート部材2は、第2ラミネート部材15と同一サイズで肉厚一定の平面形状に形成されている。第1ラミネート部材2の短手方向中央には、前記操作部7の位置を囲繞するように長方形の操作用穴3が設けられている。この操作用穴3における左右の長手辺は平行な一直線状の操作ガイド4,4を構成している。この操作用穴3内には、切替部5の操作部7が前後動可能に位置する。この操作部7の両側辺は、操作ガイド4,4でガイドされ、これにより安定して前後にスライド移動するように構成されている。第1ラミネート部材2の表面は、印刷等が施された化粧面である。  Thefirst laminate member 2 has the same size as thesecond laminate member 15 and is formed in a planar shape with a constant thickness. Arectangular operation hole 3 is provided at the center in the short direction of thefirst laminate member 2 so as to surround the position of theoperation portion 7. The left and right longitudinal sides of theoperation hole 3 constitute parallelstraight operation guides 4 and 4. In theoperation hole 3, theoperation unit 7 of theswitching unit 5 is positioned so as to be movable back and forth. Both sides of theoperation unit 7 are guided byoperation guides 4 and 4, and are configured to slide stably back and forth. The surface of thefirst laminate member 2 is a decorative surface on which printing or the like has been performed.

前記第1ラミネート部材2、板状部材6、スペーサ部材11、および第2ラミネート部材15は、紙や樹脂など通信波(電磁波や電波など)を通過許容する素材で形成すればよく、同一素材で形成する、あるいは別素材で形成することができる。  Thefirst laminate member 2, the plate-like member 6, thespacer member 11, and thesecond laminate member 15 may be formed of a material that allows transmission of communication waves (such as electromagnetic waves and radio waves) such as paper and resin. It can be formed or formed from another material.

また、板状部材6は、適度な剛性を有する素材で構成することが好ましく、第1ラミネート部材2、スペーサ部材11、および第2ラミネート部材15は、少なくとも全てが重合して接着固定された状態で適度な剛性を有する素材で構成することが好ましい。  The plate-like member 6 is preferably made of a material having moderate rigidity, and at least all of thefirst laminate member 2, thespacer member 11, and thesecond laminate member 15 are superposed and bonded and fixed. It is preferable to use a material having moderate rigidity.

また、第1ラミネート部材2、スペーサ部材11、および第2ラミネート部材15は、少なくともスライド用穴12の周囲については強固に接着固定することが好ましい。これにより、スライド用穴12の周囲の接着が剥がれて切替部5が意図しない方向へ移動することや、第1ラミネート部材2と第2ラミネート部材15の間が浮いて接点20a,20bと接点24との接触が悪くなることを防止できる。  Moreover, it is preferable that thefirst laminate member 2, thespacer member 11, and thesecond laminate member 15 are firmly bonded and fixed at least around theslide hole 12. As a result, the adhesive around theslide hole 12 is peeled off and the switchingunit 5 moves in an unintended direction, or thefirst laminate member 2 and thesecond laminate member 15 are lifted to contact thecontacts 20a, 20b and thecontact 24. It is possible to prevent the contact with the head from getting worse.

図3は、非接触ICカード1のブロック図を示す。
非接触ICカード1は、ICチップ21a,21bおよびループアンテナ22で構成されており、ループアンテナ22の接点24がICチップ21aの接点20aとICチップ21bの接点20bとのどちらに接続されるかによって、駆動するICチップを切り替えるように構成されている。
FIG. 3 shows a block diagram of thenon-contact IC card 1.
Thenon-contact IC card 1 is composed ofIC chips 21a and 21b and aloop antenna 22, and thecontact 24 of theloop antenna 22 is connected to thecontact 20a of theIC chip 21a or thecontact 20b of theIC chip 21b. Thus, the IC chip to be driven is switched.

ICチップ21aは、ループアンテナ22と並列にキャパシタ41が接続されており、該キャパシタ41の後段のアナログフロントエンド42からコマンド43および伝送クロック44がコントロールマイクロプロセッサ46に入力される。  Acapacitor 41 is connected to theIC chip 21 a in parallel with theloop antenna 22, and acommand 43 and atransmission clock 44 are input to thecontrol microprocessor 46 from ananalog front end 42 subsequent to thecapacitor 41.

コントロールマイクロプロセッサ46は、前記コマンド43および伝送クロック44を受けて、ROM、RAM、およびEEPROM等で構成されるメモリ48に対してデータの読み書きを実行し、必要に応じて暗号処理47も実行する。またコントロールマイクロプロセッサ46は、変調器45にデータを送信する。  Upon receiving thecommand 43 and thetransmission clock 44, thecontrol microprocessor 46 reads / writes data from / to amemory 48 composed of ROM, RAM, EEPROM, etc., and also executesencryption processing 47 as necessary. . Thecontrol microprocessor 46 transmits data to themodulator 45.

変調器45は、コントロールマイクロプロセッサ46から受信したデータをアナログ信号に変調し、アナログフロントエンド42に送る。このようにして、ICチップ21aは、第1の周波数を用いて動作する第1機能として、例えばキャッシュカード、クレジットカード、定期券、プリペイドカード、社員証、学生証などのアプリケーション機能を備えることができる。  Themodulator 45 modulates the data received from thecontrol microprocessor 46 into an analog signal and sends it to the analogfront end 42. In this way, theIC chip 21a may have application functions such as a cash card, a credit card, a commuter pass, a prepaid card, an employee ID card, and a student ID card as a first function that operates using the first frequency. it can.

ICチップ21bは、動作周波数やアプリケーション機能が異なる以外は、ICチップ21aと同一の構成であるので、その詳細な説明を省略する。このICチップ21bは、ICチップ21aと異なる第2の周波数を用いて動作する第2機能として、例えばキャッシュカード、クレジットカード、定期券、プリペイドカード、社員証、学生証などのアプリケーション機能のうちICチップ21aと異なるアプリケーション機能を備えることができる。  Since theIC chip 21b has the same configuration as theIC chip 21a except that the operating frequency and application functions are different, detailed description thereof is omitted. TheIC chip 21b has a second function that operates using a second frequency different from that of theIC chip 21a. For example, theIC chip 21b includes an IC function among application functions such as a cash card, a credit card, a commuter pass, a prepaid card, an employee card, and a student card. An application function different from that of thechip 21a can be provided.

以上の構成により、利用者は操作部7を操作してスライド移動させるだけで、図1(A)に示したようにICチップ21aを用いて通信する第1機能実行状態と、図1(B)に示したようにICチップ21bを用いて通信する第2機能実行状態とを容易に切り替えることができる。  With the above configuration, the user simply operates theoperation unit 7 and slides it to perform the first function execution state in which communication is performed using theIC chip 21a as illustrated in FIG. ), The second function execution state in which communication is performed using theIC chip 21b can be easily switched.

つまり、第1機能実行状態では、図1(A)に示すように操作部7が操作用穴3の手前側に位置し、図4(A)に示すように、接点20aと接点24とが接触し、ICチップ21aとループアンテナ22とが電気的に接続される。従って、適宜の質問器からループアンテナ22が受けた磁界による誘導起電力でICチップ21aが駆動でき、またICチップ21aがループアンテナ22を通じて質問器と非接触通信することができる。このとき、接点20aと接点24とが互いに突出しているため、電気的な接続を確実に行うことができる。  That is, in the first function execution state, theoperation unit 7 is positioned on the near side of theoperation hole 3 as shown in FIG. 1A, and thecontact 20a and thecontact 24 are connected as shown in FIG. 4A. TheIC chip 21a and theloop antenna 22 are electrically connected. Therefore, theIC chip 21a can be driven by the induced electromotive force generated by the magnetic field received by theloop antenna 22 from an appropriate interrogator, and theIC chip 21a can communicate with the interrogator through theloop antenna 22. At this time, since thecontact 20a and thecontact 24 protrude from each other, electrical connection can be reliably performed.

第2機能実行状態では、図1(B)に示すように操作部7が操作用穴3の奥側に位置し、図4(B)に示すように、接点20bと接点24とが接触し、ICチップ21bとループアンテナ22とが電気的に接続される。従って、適宜の質問器からループアンテナ22が受けた磁界による誘導起電力でICチップ21bが駆動でき、またICチップ21bがループアンテナ22を通じて質問器と非接触通信することができる。このとき、接点20bと接点24とが互いに突出しているため、電気的な接続を確実に行うことができる。  In the second function execution state, as shown in FIG. 1 (B), theoperation unit 7 is positioned on the back side of theoperation hole 3, and as shown in FIG. 4 (B), thecontact 20b and thecontact 24 are in contact with each other. TheIC chip 21b and theloop antenna 22 are electrically connected. Accordingly, theIC chip 21b can be driven by the induced electromotive force generated by the magnetic field received by theloop antenna 22 from an appropriate interrogator, and theIC chip 21b can communicate with the interrogator through theloop antenna 22 in a non-contact manner. At this time, since thecontact point 20b and thecontact point 24 protrude from each other, electrical connection can be reliably performed.

このように、利用者は、第1機能を実行する第1機能実行状態と、第2機能を実行する第2機能実行状態とを、操作部7を前後動させるという簡単な動作で確実に切り替えることができる。これにより、1つの非接触ICカード1を第1機能と第2機能の二つの用途で使用できる。従って、例えば第1機能としてドアの開閉機能を設定し、第2機能として鉄道の自動改札の通過機能を設定して、通常は第1機能を有効にしておき、鉄道の自動改札を通過するときに第2機能に切り替えるといった利用が可能になる。  In this way, the user reliably switches between the first function execution state for executing the first function and the second function execution state for executing the second function by a simple operation of moving theoperation unit 7 back and forth. be able to. Thereby, onenon-contact IC card 1 can be used for two uses of the first function and the second function. Therefore, for example, when the door opening / closing function is set as the first function, the automatic ticket gate passing function is set as the second function, and the first function is normally enabled and the automatic ticket gate is passed. It is possible to switch to the second function.

また、非接触ICカード1は、平面状の複数の部材を重合配置して切替部5をスライド移動可能に構成しているため、薄型のカード形状に形成するのが容易であり、安価に製造することができる。  Further, thenon-contact IC card 1 is configured to be formed into a thin card shape and manufactured at low cost because theswitching unit 5 is configured to be slidable by superposing and arranging a plurality of planar members. can do.

なお、ICチップ21(21a,21b)側の接点20(20a,20b)とループアンテナ22側の接点24とをいずれも突出させて形成したが、いずれか一方のみを突出させる、あるいは両方突出させない構成としてもよい。この場合でも、接点20,24が互いに接触さえすれば電気的に接続されるため、第1機能と第2機能の切り替えを実行することができる。  The contact 20 (20a, 20b) on the IC chip 21 (21a, 21b) side and thecontact 24 on theloop antenna 22 side are both protruded, but only one of them or both are not protruded. It is good also as a structure. Even in this case, since thecontacts 20 and 24 are electrically connected as long as they are in contact with each other, switching between the first function and the second function can be performed.

また、ICチップ21は2つとしたが、これに限らず複数備えて順次切り替え可能に構成してもよい。この場合、多種類の機能を1つの非接触ICカード1に持たせることができる。  In addition, the number ofIC chips 21 is two. In this case, onenon-contact IC card 1 can have various types of functions.

また、接点24は、接点20a,20bのいずれかと接続するかを切り替える構成としたが、これに加えていずれの接点20a,20bとも接続しない非接続状態にも切替部5で切り替え可能に構成してもよい。これにより、第1機能と第2機能のいずれも使用しない状態にして非通信状態にでき、第1機能や第2機能への不正なアクセスを回避することができる。  In addition, thecontact 24 is configured to switch between thecontact 20a and 20b, but in addition to this, theswitching unit 5 can be switched to a non-connected state in which neither of thecontacts 20a and 20b is connected. May be. As a result, neither the first function nor the second function can be used and the communication function can be disabled, and unauthorized access to the first function or the second function can be avoided.

図5は、実施例2の非接触ICタグ9の分解斜視図を示す。
この非接触ICタグ9は、実施例1のスライド方式によって接点20aと接点20bのいずれが接点24と接続するか切り替える構成と異なり、押下式によって切り替える構成にしたものであり、実施例1の非接触ICカード1より上下の厚みが厚く、前後左右の大きさが小さいタグ状のものである。
FIG. 5 is an exploded perspective view of thenon-contact IC tag 9 according to the second embodiment.
Thenon-contact IC tag 9 is configured to be switched by a push-down method, unlike the configuration of switching which of thecontact 20a and thecontact 20b is connected to thecontact 24 by the sliding method of the first embodiment. Thecontact IC card 1 has a tag shape that is thicker in the upper and lower thickness and smaller in front and rear, left and right.

この非接触ICタグ9は、板状部材6の上下両面にICチップ21a,21bがそれぞれ配置され、接点20a,20bが切替部5の一端面で上下に一直線に配置されている。切替部5の底部には、第2ラミネート部材15との間に板ばね19が備えられている。この板ばね19は、切替部5を上方へ付勢する。  In thenon-contact IC tag 9, IC chips 21 a and 21 b are respectively arranged on the upper and lower surfaces of the plate-like member 6, and thecontacts 20 a and 20 b are arranged in a straight line vertically on one end surface of theswitching unit 5. Aleaf spring 19 is provided between the bottom of theswitching unit 5 and thesecond laminate member 15. Theleaf spring 19 biases theswitching unit 5 upward.

また、切替部5は、上下面が外装部材18で覆われ、この外装部材18と板状部材6との間に充填剤17が充填されている。これにより、ICチップ21a,21bが位置ずれ等しないように構成されている。  Further, the upper and lower surfaces of theswitching unit 5 are covered with anexterior member 18, and afiller 17 is filled between theexterior member 18 and the plate-like member 6. Thus, theIC chips 21a and 21b are configured not to be displaced.

第1ラミネート部材2および切替部5の上面には、全体を覆う表面シート16が設けられている。この表面シート16は、柔軟に変形し、かつ復元する材料で構成されている。  On the upper surfaces of thefirst laminate member 2 and theswitching unit 5, asurface sheet 16 that covers the entire surface is provided. Thetop sheet 16 is made of a material that is flexibly deformed and restored.

その他の構成は、実施例1の非接触ICカード1と同一であるので、その詳細な説明を省略する。  Since other configurations are the same as those of thenon-contact IC card 1 of the first embodiment, detailed description thereof is omitted.

以上の構成により、通常状態では図5(A)に示すように接点20bと接点24され、第2機能実行状態となる。また、切替部5を押下した場合は、接点20aと接点24が接続し、第1機能実行状態となる。このようにして、第1機能と第2機能の切り替えを容易に実行できる。  With the above configuration, in the normal state, as shown in FIG. 5A, thecontact 20b and thecontact 24 are brought into a second function execution state. In addition, when theswitching unit 5 is pressed, thecontact 20a and thecontact 24 are connected to enter the first function execution state. In this way, switching between the first function and the second function can be easily performed.

なお、切替部5を押下している間のみ第1機能を実行する構成としているが、1度押下すると手を離しても押下状態を維持して第1機能実行状態を維持し、もう一度押下すると復帰して第2機能実行状態に移行する構成にしてもよい。  Note that the first function is executed only while theswitching unit 5 is pressed. However, if the switch is pressed once, the pressed function is maintained even if the hand is released, and the first function execution state is maintained. It may be configured to return to the second function execution state.

図6は、実施例3の非接触ICカード1の分解斜視図を示す。
この非接触ICカード1は、表面シート31、第1非接触ICラベル32、絶縁シート33、第2非接触ICラベル34、および背面シート35が上からこの順で重合接着されて構成されている。

Thenon-contact IC card 1 is configured by superposing and bonding atop sheet 31, a firstnon-contact IC label 32, an insulating sheet 33, a secondnon-contact IC label 34, and aback sheet 35 in this order from the top. .

上面にあたる表面シート31は、適宜の剛性を有する樹脂等の素材によってカード大に形成されており、印刷等が施された化粧面により表面が構成されている。  Thesurface sheet 31 corresponding to the upper surface is formed in a card size with a material such as resin having appropriate rigidity, and the surface is constituted by a decorative surface on which printing or the like is applied.

第1非接触ICラベル32は、フィルムにプリント配線したループアンテナ22aと、ICチップ21aとが設けられており、ループアンテナ22aとICチップ21aは接続されている。このICチップ21aは、例えば0.8GHzの周波数帯で通信する第1機能を備えている。  The firstnon-contact IC label 32 is provided with aloop antenna 22a printed on a film and anIC chip 21a, and theloop antenna 22a and theIC chip 21a are connected. TheIC chip 21a has a first function for communicating in a frequency band of 0.8 GHz, for example.

TheIC chip 21b has a second function of communicating in a 13.56 MHz frequency band, for example.

底面にあたる背面シート35は、適宜の剛性を有する樹脂等の素材によってカード大に形成されており、外側面である裏面に、磁気ストライプ36を備えている。この裏面の磁気ストライプ36以外の部分は、印刷等が施された化粧面である。  Theback sheet 35 corresponding to the bottom surface is formed in a card size with a material such as resin having appropriate rigidity, and includes amagnetic stripe 36 on the back surface which is the outer surface. The portion other than themagnetic stripe 36 on the back surface is a decorative surface on which printing or the like has been performed.

以上の構成により、1つの非接触ICカード1に複数の機能を持たせることができる。つまり、複数の非接触ICラベル(32,34)を備えることで、第1機能と第2機能のそれぞれをいつでも実行することができる。第1非接触ICラベル32と第2非接触ICラベル34は、絶縁シート33で分離されているため、互いのループアンテナ22a,22bが干渉し合うことを防止できる。  With the above configuration, onenon-contact IC card 1 can have a plurality of functions. That is, by providing a plurality of non-contact IC labels (32, 34), each of the first function and the second function can be executed at any time. Since the firstnon-contact IC label 32 and the secondnon-contact IC label 34 are separated by the insulating sheet 33, themutual loop antennas 22a and 22b can be prevented from interfering with each other.

なお、以上の各実施形態では、非接触ICカード1で説明したが、カード型のものに限らず、携帯電話機に備えた非接触IC媒体や、紙タイプやシールタイプの非接触ICタグに備えられた非接触IC媒体により構成してもよい。この場合でも、同一の作用効果を奏することができる。  In the above embodiments, thenon-contact IC card 1 has been described.

この非接触ICカード1は、表面シート31、第1非接触ICラベル32、セパレータ50、第2非接触ICラベル34、および背面シート35が上からこの順で重合接着されて構成されている。
FIG. 7 shows an exploded perspective view of thenon-contact IC card 1 of the fourth embodiment, and FIG. 8 shows a partially enlarged sectional view of thenon-contact IC card 1 of the fourth embodiment.
Thenon-contact IC card 1 is configured by superposing and bonding atop sheet 31, a firstnon-contact IC label 32, aseparator 50, a secondnon-contact IC label 34, and aback sheet 35 in this order from the top.

上面にあたる表面シート31は、適宜の剛性を有する樹脂等の素材によってカード大(カードサイズ)に形成されており、印刷等が施された化粧面により表面が構成されている。  Thetop sheet 31 corresponding to the upper surface is formed in a card size (card size) by a material such as resin having an appropriate rigidity, and the surface is constituted by a decorative surface on which printing or the like is applied.

第1非接触ICラベル32は、フィルムにプリント配線したループアンテナ22aと、ICチップ21aとが互いに接続されて設けられている。このICチップ21aは、ICチップ21bと同一の周波数帯でICチップ21bよりも強い電磁波を受けて通信するように構成されている。このICチップ21aは、例えば13.56MHzの周波数帯でリーダライタと30cm程度はなれた位置から非接触通信できる構成とされており、例えば鉄道の乗車券として利用できる第1機能を備えている。ICチップ21aの構成は、図3と共に説明した実施例1のICチップ21aと同一であるので、その詳細な説明を省略する。  The firstnon-contact IC label 32 is provided by connecting aloop antenna 22a printed on a film and anIC chip 21a to each other. TheIC chip 21a is configured to receive and communicate with an electromagnetic wave stronger than theIC chip 21b in the same frequency band as theIC chip 21b. TheIC chip 21a is configured to be able to perform non-contact communication with a reader / writer at a position separated from the reader / writer by a frequency band of 13.56 MHz, for example, and has a first function that can be used as, for example, a railroad ticket. Since the configuration of theIC chip 21a is the same as theIC chip 21a of the first embodiment described with reference to FIG. 3, detailed description thereof is omitted.

セパレータ50は、炭素などの絶縁素材によってカード大に形成されているシートである。
このセパレータ50は、中間層として設けられたカード大の電磁波遮断層52と、該電磁波遮断層52よりも第1非接触ICラベル32側に重合配置されたカード大の第1電磁波吸収層51と、該電磁波遮断層52よりも第2非接触ICラベル34側に重合配置されたカード大の第2電磁波吸収層53とで構成されている。
Theseparator 50 is a sheet that is formed on a large card by an insulating material such as carbon.
Theseparator 50 includes a card-sized electromagneticwave blocking layer 52 provided as an intermediate layer, and a card-sized first electromagneticwave absorbing layer 51 arranged on the firstnon-contact IC label 32 side with respect to the electromagneticwave blocking layer 52. The second electromagneticwave absorption layer 53 is a card-sized second electromagneticwave absorption layer 53 that is superposed on the secondnon-contact IC label 34 side of the electromagneticwave shielding layer 52.

ここで、電磁波遮断層52は、アルミ又は銅などの電磁波遮断材料で構成されている。
第1電磁波吸収層51は、軟磁性体など電磁波を分散、吸収する材料で構成されている。この実施例では、第2電磁波吸収層53よりも電磁波吸収能力を強めるべく、パーマロイを用いて構成されている。
Here, the electromagneticwave shielding layer 52 is made of an electromagnetic wave shielding material such as aluminum or copper.
The first electromagneticwave absorbing layer 51 is made of a material that disperses and absorbs electromagnetic waves, such as a soft magnetic material. In this embodiment, permalloy is used in order to enhance the electromagnetic wave absorption capability of the second electromagneticwave absorption layer 53.

第2電磁波吸収層53は、軟磁性体など電磁波を分散、吸収する材料で構成されている。この実施例では、第1電磁波吸収層51よりも電磁波吸収能力を弱めるべく、金属磁性体フレークを樹脂に充填して形成されている。肉厚は、0.5mm〜0.25mm程度の厚みが好ましく、この実施形態では0.25mm程度に形成されている。またこの第2電磁波吸収層53は、推奨周波数帯域を100MHz〜3GHz程度とし、初透磁率(at 10MHz)が21〜32程度となるように形成されている。この第2電磁波吸収層53の素材には、第1電磁波吸収層51よりも電磁波吸収能力を弱めるべく、フェライト等を用いることが好ましい。  The second electromagneticwave absorbing layer 53 is made of a material that disperses and absorbs electromagnetic waves, such as a soft magnetic material. In this embodiment, in order to weaken the electromagnetic wave absorption capability of the first electromagneticwave absorption layer 51, it is formed by filling a metal magnetic flake into a resin. The thickness is preferably about 0.5 mm to 0.25 mm. In this embodiment, the thickness is about 0.25 mm. The second electromagneticwave absorbing layer 53 is formed so that the recommended frequency band is about 100 MHz to 3 GHz and the initial permeability (at 10 MHz) is about 21 to 32. For the material of the second electromagneticwave absorption layer 53, it is preferable to use ferrite or the like in order to weaken the electromagnetic wave absorption capability of the first electromagneticwave absorption layer 51.

第2非接触ICラベル34は、フィルムにプリント配線したループアンテナ22bと、ICチップ21bとが互いに接続されて設けられている。このICチップ21bは、ICチップ21aと同一の周波数帯でICチップ21aよりも弱い電磁波を受けて通信するように構成されている。このICチップ21bは、例えば13.56MHzの周波数帯でリーダライタと10cm程度はなれた位置(ICチップ21aの場合よりも短い距離)から非接触通信できる通信できる構成とされており、たとえばキャッシングに用いることとができる第2機能を備えている。ICチップ21bの構成は、図3と共に説明した実施例1のICチップ21bと同一であるので、その詳細な説明を省略する。  The secondnon-contact IC label 34 is provided by connecting aloop antenna 22b printed on a film and anIC chip 21b. TheIC chip 21b is configured to receive and communicate with an electromagnetic wave weaker than theIC chip 21a in the same frequency band as theIC chip 21a. TheIC chip 21b is configured to be able to perform non-contact communication from a position (distance shorter than the case of theIC chip 21a) separated from the reader / writer by about 10 cm in a frequency band of 13.56 MHz, for example, and is used for caching, for example. The second function is provided. Since the configuration of theIC chip 21b is the same as theIC chip 21b of the first embodiment described with reference to FIG. 3, detailed description thereof is omitted.

底面にあたる背面シート35は、適宜の剛性を有する樹脂等の素材によってカード大に形成されており、外側面である裏面に、磁気ストライプ36を備えている。この裏面の磁気ストライプ36以外の部分は、印刷等が施された化粧面である。  Theback sheet 35 corresponding to the bottom surface is formed in a large card by a material such as resin having appropriate rigidity, and includes amagnetic stripe 36 on the back surface which is the outer surface. The portion other than themagnetic stripe 36 on the back surface is a decorative surface on which printing or the like has been performed.

以上の構成により、1つの非接触ICカード1に複数の機能を持たせることができる。つまり、複数の非接触ICラベル(32,34)を備えることで、第1機能と第2機能のそれぞれをいつでも実行することができる。第1非接触ICラベル32と第2非接触ICラベル34は、セパレータ50で分離されているため、互いのループアンテナ22a,22bが干渉し合うことを防止できる。  With the above configuration, onenon-contact IC card 1 can have a plurality of functions. That is, by providing a plurality of non-contact IC labels (32, 34), each of the first function and the second function can be executed at any time. Since the firstnon-contact IC label 32 and the secondnon-contact IC label 34 are separated by theseparator 50, themutual loop antennas 22a and 22b can be prevented from interfering with each other.

また、セパレータ50に設けられた第1電磁波吸収層51と第2電磁波吸収層53との電磁波吸収性能を異ならせているため、第1非接触ICラベル32と第2非接触ICラベル34の各通信を確実に実行させることができる。  Further, since the electromagnetic wave absorption performance of the first electromagneticwave absorption layer 51 and the second electromagneticwave absorption layer 53 provided in theseparator 50 is different, each of the firstnon-contact IC label 32 and the secondnon-contact IC label 34 is provided. Communication can be executed reliably.

詳述すると、例えば第2電磁波吸収層53を第1電磁波吸収層51と同一の電磁波吸収性能を有するように構成すると、第1非接触ICラベル32は強い磁界で良好に通信できるが、第2非接触ICラベル34と弱い磁界で通信しようとしても第2電磁波吸収層53の電磁波吸収性能が強すぎて通信できなくなることがある。また、逆に第1電磁波吸収層51を第2電磁波吸収層53と同一の電磁波吸収性能を有するように構成すると、第2非接触ICラベル34は弱い磁界で良好に通信できるが、第1非接触ICラベル32と強い磁界で通信しようとすると第2非接触ICラベル34までもが反応して電磁波が混線することがある。このような問題を、第1電磁波吸収層51と第2電磁波吸収層53との電磁波吸収性能を異ならせることで解決することができる。  More specifically, for example, if the second electromagneticwave absorption layer 53 is configured to have the same electromagnetic wave absorption performance as the first electromagneticwave absorption layer 51, the firstnon-contact IC label 32 can communicate well with a strong magnetic field, but the second Even when trying to communicate with thenon-contact IC label 34 with a weak magnetic field, the electromagnetic wave absorbing performance of the second electromagneticwave absorbing layer 53 may be too strong to communicate. Conversely, if the first electromagneticwave absorbing layer 51 is configured to have the same electromagnetic wave absorbing performance as the second electromagneticwave absorbing layer 53, the secondnon-contact IC label 34 can communicate well with a weak magnetic field, When trying to communicate with thecontact IC label 32 with a strong magnetic field, even the secondnon-contact IC label 34 may react and electromagnetic waves may be mixed. Such a problem can be solved by making the electromagnetic wave absorbing performances of the first electromagneticwave absorbing layer 51 and the second electromagneticwave absorbing layer 53 different.

また、通信に強い電磁波を用いる第1非接触ICラベル32側の第1電磁波吸収層51の材質を第2電磁波吸収層53の材質よりも電磁波吸収性能が高いものにしたため、全体を肉薄に構成することができる。
つまり、仮に同一の材質を用いて第1電磁波吸収層51と第2電磁波吸収層53とを作成する場合、第1電磁波吸収層51の電磁波吸収性能を高めるために第1電磁波吸収層51を第2電磁波吸収層53より肉厚に形成する必要が生じ、非接触ICカード1の全体の肉厚が厚くなってしまう。しかし、この実施例4のように異なる材料とすることで、全体の肉厚を薄くすることができる。
In addition, since the material of the first electromagneticwave absorption layer 51 on the firstnon-contact IC label 32 side that uses electromagnetic waves strong for communication is made higher in electromagnetic wave absorption performance than the material of the second electromagneticwave absorption layer 53, the entire structure is thin. can do.
That is, if the first electromagneticwave absorbing layer 51 and the second electromagneticwave absorbing layer 53 are formed using the same material, the first electromagneticwave absorbing layer 51 is used to improve the electromagnetic wave absorbing performance of the first electromagneticwave absorbing layer 51. 2 The electromagneticwave absorbing layer 53 needs to be formed thicker, and the entire thickness of thenon-contact IC card 1 is increased. However, the overall thickness can be reduced by using different materials as in the fourth embodiment.

なお、第1電磁波吸収層51や第2電磁波吸収層53の材質は、パーマロイやフェライトに限らず、酸化鉄、クロム、ニッケル、アモルファス合金、電磁鋼、珪素鉄、Fe−AL合金、センダスト合金、カルボニル鉄、またはこれらの複数の材料の混合材料で構成してもよい。  The material of the first electromagneticwave absorbing layer 51 and the second electromagneticwave absorbing layer 53 is not limited to permalloy or ferrite, but iron oxide, chromium, nickel, amorphous alloy, electromagnetic steel, silicon iron, Fe-AL alloy, Sendust alloy, You may comprise carbonyl iron or the mixed material of these several materials.
