Description

本発明は、ＳＤメモリカードやマルチメディアカード（ＭＭＣカード）のようなメモリカードに非接触通信によって外部とのデータ授受を行うＩＣカード機能を持たせたメモリカードを挿抜自在に接続するためのメモリカード用ソケットに関するものである。   The present invention relates to a memory for detachably connecting a memory card having an IC card function for exchanging data with the outside by contactless communication to a memory card such as an SD memory card or a multimedia card (MMC card). This relates to card sockets.

従来、デジタルカメラや携帯電話機などの電子機器におけるデータ記憶手段として、カード型のハウジングにフラッシュメモリのような不揮発性メモリを内蔵したメモリカード、例えばＳＤメモリカード（登録商標）やマルチメディアカード（登録商標）が急速に普及してきた。そして、かかるメモリカードを挿抜自在に接続するためのメモリカード用ソケットとして、前方に開口したカード挿入口を通してメモリカードが内部に挿入されるハウジングと、ハウジング内に設けられメモリカードが有する接続端子に接触導通する複数のコンタクトと、ハウジング内でメモリカードの挿抜方向にスライド自在に設けられカード挿入口から挿入されるメモリカードに連動してハウジング内をスライド移動するスライド部材と、ハウジングに対してカード挿入口に向かう向きにスライド部材を付勢する付勢ばねと、メモリカードの接続端子がコンタクトに接触する保持位置よりも奥のロック位置までスライド部材が押し込まれるとスライド部材のカード挿入口へ向かう向きへの移動を禁止するとともに、スライド部材がロック位置よりも奥まで一旦押し込まれた状態で押力が解除されるとスライド部材を解放するプッシュオン・プッシュオフ型のロック機構とを備えたものが従来より提供されている（例えば、特許文献１参照）。   Conventionally, as a data storage means in an electronic device such as a digital camera or a mobile phone, a memory card such as an SD memory card (registered trademark) or a multimedia card (registration) in which a nonvolatile memory such as a flash memory is built in a card type housing Trademark) has become widespread. Then, as a memory card socket for removably connecting such a memory card, a housing into which the memory card is inserted through a card insertion opening opened forward, and a connection terminal provided in the housing and provided in the memory card A plurality of contacts that conduct contact, a slide member that is slidable in the insertion / extraction direction of the memory card in the housing and that slides in the housing in conjunction with the memory card inserted from the card insertion slot, and the card with respect to the housing A biasing spring that biases the slide member in a direction toward the insertion slot, and when the slide member is pushed to a locked position deeper than the holding position where the connection terminal of the memory card contacts the contact, the slide card moves toward the card insertion slot. Prohibits movement in the direction and locks the slide member In the past, there has been provided a push-on / push-off type locking mechanism that releases a slide member when the pressing force is released in a state where it is once pushed to the back of the device (for example, Patent Document 1). reference).

上記のようにプッシュオン・プッシュオフ型のロック機構を備えたメモリカード用ソケットにメモリカードを接続する際は、メモリカードをハウジングに挿入して押し込むと、スライド部材がメモリカードを介して押力を受け、メモリカードの接続端子がコンタクトに接触する保持位置よりもやや奥のロック位置まで移動したときに、カード挿入口へ向かう向きへのスライド部材の移動がロック機構によって禁止され、メモリカードへの押力を除去した後にもメモリカードが保持位置に留まることになる。一方、メモリカードを抜く際には、ロック位置よりも少し奥にメモリカードを一旦押し込んでからメモリカードへの押力を除去すると、ロック機構がスライド部材を解放し、メモリカードがスライド部材を介して付勢ばねのばね力を受け、ハウジングから押し出される。   When a memory card is connected to a memory card socket having a push-on / push-off type locking mechanism as described above, the slide member is pushed through the memory card by inserting the memory card into the housing. When the memory card connection terminal moves to the lock position slightly behind the holding position where it contacts the contact, the lock mechanism prohibits the movement of the slide member toward the card insertion slot. Even after the pressing force is removed, the memory card remains in the holding position. On the other hand, when removing the memory card, once the memory card is pushed slightly inward from the lock position and the pressing force on the memory card is removed, the lock mechanism releases the slide member, and the memory card passes through the slide member. Then, it receives the spring force of the biasing spring and is pushed out of the housing.

ところで、非接触通信によって外部との間でデータを授受するＩＣカード機能を持たせたメモリカード（例えば、「SmartＳＤ」）が今後普及すると予測される。かかるＩＣカード機能付きのメモリカードには非接触通信用のアンテナが内蔵されているが、メモリカード自体が小型であるために内蔵アンテナも必然的に小型になり、通信距離の確保が重要な課題となる。例えば特許文献２には、アンテナを内蔵したクレジットカード型のアダプタにＩＣカード機能付きメモリカードを装着することで通信距離を確保する技術が開示されている。
特開２００５−２６０１６号公報 特開２００２−２７９３７７号公報 By the way, it is predicted that a memory card (for example, “SmartSD”) having an IC card function for exchanging data with the outside by non-contact communication will be widely used in the future. Such a memory card with an IC card function has a built-in non-contact communication antenna. However, since the memory card itself is small, the built-in antenna is inevitably small, and it is important to secure a communication distance. It becomes. For example, Patent Document 2 discloses a technique for securing a communication distance by attaching a memory card with an IC card function to a credit card type adapter with a built-in antenna.
JP 200526016 A JP 2002-279377 A

しかしながら、特許文献２に記載されている従来例のようにクレジットカード型のアダプタを使用した場合、従来のメモリカード用ソケットには装着することができず、専用のソケットを新たに設計し直す必要があり、ソケットが大型化するとともにコストが大幅に増大するという問題があった。   However, when a credit card type adapter is used as in the conventional example described in Patent Document 2, it cannot be attached to a conventional memory card socket, and a dedicated socket needs to be redesigned. There is a problem that the socket is increased in size and the cost is significantly increased.

本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、コストアップや大型化を招くことなく通信距離を延ばすことができるメモリカード用ソケットを提供することにある。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a memory card socket capable of extending the communication distance without increasing the cost or increasing the size.

This socket 1 has almost the same configuration and function as a conventional socket that does not have a non-contact communication function. By inserting and pushing the memory card MC into the card accommodating portion 2b through the card insertion slot 2a, the socket 1 When the memory card MC is held at a predetermined lock position and then the pressing force is released with the memory card MC once pushed to the back of the lock position, the memory card MC is unlocked and the memory card MC is pushed out from the card insertion slot 2a. It is like that. That is, the socket 1 has a so-called push-on / push-off function.

図１及び図３は本実施形態の外観斜視図、図４は本実施形態の分解斜視図であり、このソケット１は、一側面（挿入方向手前側の前面）に細長い帯状のカード挿入口２ａが開口した扁平な箱状のケース２と、ケース２の内部にカード挿入口２ａに連通して設けられたカード収容部２ｂ内でカード挿入口２ａ側と奥側との間で進退自在に配置されたスライダ５と、スライダ５をカード挿入口２ａ側に付勢するコイルスプリング６と、カード収容部２ｂの奥側に左右方向に並べて配列され、メモリカードＭＣの接続端子１０１にそれぞれ電気的に接続される複数本（９本）の接触端子７とを備えている。   FIGS. 1 and 3 are external perspective views of the present embodiment, and FIG. 4 is an exploded perspective view of the present embodiment. The socket 1 has a strip-like card insertion slot 2a elongated on one side surface (front surface in the insertion direction side). A flat box-like case 2 having an opening and a card insertion portion 2b provided inside the case 2 so as to communicate with the card insertion port 2a. The card case 2b can be moved back and forth between the card insertion port 2a side and the back side. The slider 5, the coil spring 6 that urges the slider 5 toward the card insertion slot 2a, and the back side of the card housing 2b are arranged side by side in the left-right direction, and are electrically connected to the connection terminals 101 of the memory card MC. A plurality of (9) contact terminals 7 to be connected are provided.

ケース２は、絶縁性を有する合成樹脂成型品からなるベースシェル３と、導電材料又は磁性材料の何れかで、且つ、熱伝導性の良好な金属薄板（本実施形態では例えばステンレススチール）により形成されたカバーシェル４とを相互に結合して構成されている。   The case 2 is formed of a base shell 3 made of a synthetic resin molded product having insulating properties, and a thin metal plate (for example, stainless steel in the present embodiment) made of either a conductive material or a magnetic material and having good thermal conductivity. The cover shell 4 is connected to each other.

ベースシェル３は、平板状であって前縁の中央部に切欠３ｂを設けることによって平面視の形状が略コ字形に形成された底板部３ａと、底板部３ａの後部から上側に向かって立設されカード収容部２ｂのカード挿入方向奥側端を閉塞する奥壁部３ｃと、底板部３ａの左右両側部からそれぞれ上側に向かって立設されカード収容部２ｂの左右の壁をなす一対の側壁部３ｄ，３ｅとを一体に備えており、各側壁部３ｄ，３ｅの外側面には、後述するカバーシェル４の係止孔４ｄにそれぞれ係止する係止爪３ｆが複数個突設されている。   The base shell 3 has a flat plate shape, a bottom plate portion 3a having a substantially U-shaped shape in plan view by providing a notch 3b in the center of the front edge, and a base plate 3 standing upward from the rear portion of the bottom plate portion 3a. A pair of wall portions 3c that are provided and block the back end in the card insertion direction of the card storage portion 2b, and a pair of walls that are erected upward from the left and right side portions of the bottom plate portion 3a and that form the left and right walls of the card storage portion 2b. The side walls 3d and 3e are integrally provided, and a plurality of locking claws 3f that respectively lock into locking holes 4d of the cover shell 4 described later are provided on the outer surface of the side walls 3d and 3e. ing.

またカバーシェル４は、平板状であって前縁の中央部に切欠４ｂを設けることによって平面視の形状が略コ字形に形成された天板部４ａを備え、天板部４ａの幅方向両側辺からそれぞれ側方に延長形成された突出部分を略直角に折り曲げて複数の係止片４ｃを形成してあり、各係止片４ｃにはベースシェル３の係止爪３ｆが係止する係止孔４ｄをそれぞれ形成してある。ここにおいて、天板部４ａの切欠４ｂが設けられた部位の前縁は、カード収容部２ｂ内にメモリカードＭＣを収容した状態で、メモリカードＭＣに内蔵されたロ字形の内蔵アンテナ１００の後側の辺１００ａよりも前側に位置しており、内蔵アンテナ１００の後側辺１００ａは天板部４ａの一部（２次アンテナ部１０ａ）によって覆われている。   The cover shell 4 is flat and includes a top plate portion 4a having a substantially U-shaped plan view by providing a notch 4b at the center of the front edge, and both sides of the top plate portion 4a in the width direction. A plurality of locking pieces 4c are formed by bending the protruding portions extending laterally from the sides substantially at right angles, and the locking claws 3f of the base shell 3 are locked to the locking pieces 4c. Stop holes 4d are respectively formed. Here, the front edge of the portion of the top plate portion 4a where the notch 4b is provided is the rear edge of the rectangular internal antenna 100 incorporated in the memory card MC in a state where the memory card MC is accommodated in the card accommodation portion 2b. The rear side 100a of the built-in antenna 100 is covered with a part of the top plate part 4a (secondary antenna part 10a).

而してカバーシェル４は、左右両側部に設けた係止片４ｃの係止孔４ｄをベースシェル３に設けた係止爪３ｆと係止させることで、ベースシェル３の上側開口を覆うように取り付けられるのである（図１および図３参照）。そして、ベースシェル３とカバーシェル４とを結合して一体化することによりケース２が形成される。この時、ベースシェル３において奥壁部３ｃと反対側の端部がカード収容部２ｂの入口（つまりカード挿入口２ａ）となり、メモリカードＭＣはカード挿入口２ａを通してカード収容部２ｂ内に挿入されるのである。   Thus, the cover shell 4 covers the upper opening of the base shell 3 by locking the locking holes 4 d of the locking pieces 4 c provided on the left and right sides with the locking claws 3 f provided on the base shell 3. (See FIGS. 1 and 3). Then, the case 2 is formed by combining and integrating the base shell 3 and the cover shell 4. At this time, the end of the base shell 3 opposite to the back wall 3c becomes the entrance (that is, the card insertion slot 2a) of the card accommodation section 2b, and the memory card MC is inserted into the card accommodation section 2b through the card insertion slot 2a. It is.

スライダ５は、カード収容部２ｂの内部に、カード挿入口２ａ側と奥側との間（つまり前後方向）に進退可能な状態で取着されている。このスライダ５は、メモリカードＭＣの先端面１０４に当接する奥壁部５ａと、傾斜カット部１０２に当接する角壁部５ｂと、メモリカードＭＣの左側部に当接する側壁部５ｃとを一体に備えて、平面視の形状が略Ｌ字状に形成されている。そして、カード挿入口２ａを通してカード収容部２ｂにメモリカードＭＣが挿入されると、メモリカードＭＣの先端面１０４および傾斜カット部１０２が、それぞれ奥壁部５ａおよび角壁部５ｂの内壁に衝合するとともに、その状態でメモリカードＭＣが図示しない係止機構によってスライダ５に係止され、保持されるようになっており、この保持状態でメモリカードＭＣはスライダ５とともにカード収容部２ｂ内を前後方向に進退するのである。なお、カバーシェル４の天板部４ａの奥側部分には、スライダ５がメモリカードＭＣとともにカード収容部２ｂ内の奥側に移動して、メモリカードＭＣの接続端子１０１に対応する接触端子７が弾接した際に、メモリカードＭＣと反対側に撓められた接触端子７がケース２（すなわち天板部４ａ）と干渉するのを避けるための逃がし孔９が各接触端子７に対応して複数個（本実施形態では８個）形成されている。   The slider 5 is attached to the inside of the card accommodating portion 2b so as to be able to advance and retreat between the card insertion slot 2a side and the back side (that is, the front-rear direction). The slider 5 has a back wall portion 5a that contacts the front end surface 104 of the memory card MC, a square wall portion 5b that contacts the inclined cut portion 102, and a side wall portion 5c that contacts the left side portion of the memory card MC. In addition, the shape in plan view is formed in a substantially L shape. When the memory card MC is inserted into the card accommodation portion 2b through the card insertion slot 2a, the front end surface 104 and the inclined cut portion 102 of the memory card MC collide with the inner walls of the back wall portion 5a and the corner wall portion 5b, respectively. In this state, the memory card MC is locked and held by the slider 5 by a locking mechanism (not shown). In this holding state, the memory card MC moves forward and backward in the card accommodating portion 2b together with the slider 5. It advances and retreats in the direction. At the back side of the top plate portion 4a of the cover shell 4, the slider 5 moves to the back side in the card housing portion 2b together with the memory card MC, and the contact terminal 7 corresponding to the connection terminal 101 of the memory card MC. The contact holes 7 for avoiding the contact terminals 7 deflected to the opposite side of the memory card MC from interfering with the case 2 (that is, the top plate portion 4a) correspond to the contact terminals 7 when they are elastically contacted. A plurality (eight in this embodiment) are formed.

ここにおいて、カード収容部２ｂ内におけるスライダ５の位置は、図示しないハートカム機構と、スライダ５をカード挿入口２ａ側に付勢するコイルスプリング６とを含む従来周知のプッシュオン・プッシュオフ機構によって制御される。ハートカム機構は、一例としてスライダ５又はケース２（ベースシェル３）のうち何れか一方にガイド溝を設けるとともに、スライダ５又はケース２の他方にガイド溝内に案内される案内子を設けることによって構成される。ハートカム機構を構成するガイド溝は、その所定区間をスライダ５の前後動に応じて案内子を一方向に案内する経路とし、その経路によって囲まれる部位に平面視ハート形のハートカムを設けてあり、ロック位置においてハートカムの凹部に案内子を係止させることで、スライダ５をロック位置に保持し前方への移動を規制するようになっている。   Here, the position of the slider 5 in the card accommodating portion 2b is controlled by a conventionally known push-on / push-off mechanism including a heart cam mechanism (not shown) and a coil spring 6 that urges the slider 5 toward the card insertion slot 2a. Is done. As an example, the heart cam mechanism is configured by providing a guide groove in one of the slider 5 or the case 2 (base shell 3) and providing a guide guided in the guide groove on the other of the slider 5 or the case 2. Is done. The guide groove constituting the heart cam mechanism has a predetermined section as a path for guiding the guide element in one direction according to the back and forth movement of the slider 5, and a heart-shaped heart cam in a plan view is provided at a portion surrounded by the path. The slider 5 is held at the lock position and the forward movement is restricted by locking the guide element in the recess of the heart cam at the lock position.

またコイルスプリング６は、本実施形態では引張ばねとして機能し、ベースシェル３の側壁部３ｄにおけるカード挿入口２ａ側の部位に設けた突起３ｇと、スライダ５の側壁部５ｃに設けた突起５ｄとの間に懸架され、スライダ５に対してカード収容部２ｂの入口側（つまりカード挿入口２ａ側）に付勢する付勢力を作用させている。   In addition, the coil spring 6 functions as a tension spring in the present embodiment, and includes a protrusion 3g provided on the side of the side wall 3d of the base shell 3 on the card insertion slot 2a side, and a protrusion 5d provided on the side wall 5c of the slider 5. A biasing force is applied to the slider 5 so as to bias the slider 5 toward the inlet side (that is, the card insertion slot 2a side) of the card accommodating portion 2b.

接触端子７は、それぞれ弾性および導電性を有する金属材料により短冊状に形成されて、ベースシェル３の奥壁部３ｃに固定されており、カード収容部２ｂの内部で、その奥側からカード挿入口１ｂ側に向かって延出している。各接触端子７のカード挿入口２ａ側の端部７ａは略く字形に折曲されており、カード収容部２ｂ内に挿入されたメモリカードＭＣの接続端子１０１に弾接する。一方、各接触端子７の反対側の端部７ｂは、奥壁部３ｃの後面から突出し、その先端側はベースシェル３の下面と平行な方向に延出しており、この先端側が電子機器に設けられた回路基板等に半田付けされる端子となっている。なお、接触端子７は、ベースシェル３の奥壁部３ｃにインサート成形によって固定しても良いし、圧入などの方法で固定しても良い。   The contact terminals 7 are each formed in a strip shape by a metal material having elasticity and conductivity, and are fixed to the back wall portion 3c of the base shell 3, and the card is inserted from the back side inside the card housing portion 2b. It extends toward the mouth 1b side. The end 7a of each contact terminal 7 on the side of the card insertion slot 2a is bent in a substantially square shape and elastically contacts the connection terminal 101 of the memory card MC inserted in the card accommodating portion 2b. On the other hand, the end portion 7b on the opposite side of each contact terminal 7 protrudes from the rear surface of the back wall portion 3c, and its front end side extends in a direction parallel to the lower surface of the base shell 3, and this front end side is provided in the electronic device. The terminal is soldered to the circuit board or the like. The contact terminal 7 may be fixed to the back wall 3c of the base shell 3 by insert molding, or may be fixed by a method such as press fitting.

ところで、メモリカードＭＣは内蔵アンテナ１００および集積回路を内蔵し、外部のリーダライタ装置との間で非接触通信によりデータを授受する機能を備えているが、本実施形態のソケット１では、メモリカードＭＣの通信性能を向上させ、通信可能距離を延ばすために、メモリカードＭＣをカード収容部２ｂ内に収容するケース２において、メモリカードＭＣの主平面（すなわち内蔵アンテナ１００が近接して配置された側の主表面（上面））に対向する面であって、リーダライタ装置側の面（上面）を導電材料又は磁性材料の何れかで形成されたカバーシェル４で構成し、このカバーシェル４と一体に、メモリカードＭＣの主平面の法線方向において内蔵アンテナ１００の後側辺１００ａと重なる２次アンテナ部１０ａを設けている。   By the way, the memory card MC has a built-in antenna 100 and an integrated circuit, and has a function of exchanging data with an external reader / writer device by non-contact communication. In order to improve the communication performance of the MC and extend the communicable distance, in the case 2 in which the memory card MC is accommodated in the card accommodating portion 2b, the main plane of the memory card MC (that is, the built-in antenna 100 is disposed close to the memory card MC). And the reader / writer device side surface (upper surface) is configured by a cover shell 4 formed of either a conductive material or a magnetic material. A secondary antenna portion 10a is provided integrally with the rear side 100a of the built-in antenna 100 in the normal direction of the main plane of the memory card MC.

したがって、ソケット１のカード収容部２ｂ内にメモリカードＭＣが収容された状態では、カバーシェル４と一体に設けた２次アンテナ部１０ａが、メモリカードＭＣの内蔵アンテナ１００の後側辺１００ａとメモリカードＭＣの主平面（上面）の法線方向において重なるので、メモリカードＭＣの主平面に対向する面で、リーダライタ装置側の面に磁界（磁束）が集まりやすくなり、リーダライタ装置の磁界（磁束）が引き込まれることによって、メモリカードＭＣの内蔵アンテナ１００に対してブースターアンテナ（２次アンテナ）の役割を果たし、その結果メモリカードＭＣとリーダライタ装置との間の非接触通信の性能が向上し、通信距離を延ばすことができる。   Therefore, in a state where the memory card MC is accommodated in the card accommodating portion 2b of the socket 1, the secondary antenna portion 10a provided integrally with the cover shell 4 is connected to the rear side 100a of the built-in antenna 100 of the memory card MC and the memory. Since they overlap in the normal direction of the main plane (upper surface) of the card MC, a magnetic field (magnetic flux) tends to collect on the surface facing the main plane of the memory card MC on the side of the reader / writer device, and the magnetic field ( The magnetic flux) acts as a booster antenna (secondary antenna) for the built-in antenna 100 of the memory card MC. As a result, the performance of contactless communication between the memory card MC and the reader / writer device is improved. In addition, the communication distance can be extended.

ところで、上記実施形態のソケット１では、メモリカードＭＣが内蔵する内蔵アンテナ１００の１つの辺１００ａと上下方向（つまりメモリカードＭＣの主表面の法線方向）において重なり合う２次アンテナ部１０ａをカバーシェル４と一体に設けているが、内蔵アンテナ１００の少なくとも一部と重なる部位に２次アンテナ部を設けることで、非接触通信の通信性能を向上させることができる。   By the way, in the socket 1 of the above embodiment, the secondary antenna portion 10a that overlaps with one side 100a of the built-in antenna 100 built in the memory card MC in the vertical direction (that is, the normal direction of the main surface of the memory card MC) is covered with the cover shell. 4, the secondary antenna unit is provided in a portion that overlaps at least a part of the built-in antenna 100, thereby improving the communication performance of non-contact communication.

例えば図５および図６（ａ）に示すように内蔵アンテナ１００の左右の辺１００ｂ，１００ｃと上下方向において重なり合う２次アンテナ部１０ｂ，１０ｃをカバーシェル４と一体に設けても良い。この場合は、天板部４ａの切欠４ｂが設けられた部位の前縁は、カード収容部２ｂ内にメモリカードＭＣを収容した状態で、メモリカードＭＣの内蔵アンテナ１００の後側辺１００ａよりも後側に位置し、且つ、切欠４ｂが設けられた部位の左右の側縁は、内蔵アンテナ１００の左右の辺１００ｂ，１００ｃよりも内側に位置しており、内蔵アンテナ１００の後側辺１００ａは露出する一方、左右両側辺１００ｂ，１００ｃが２次アンテナ部１０ｂ，１０ｃによって覆われているので、図１のソケット１に比べて、内蔵アンテナ１００に対するブースタアンテナの役割がより大きくなり、メモリカードＭＣとリーダライタ装置との間の通信距離をさらに延ばすことができる。   For example, as shown in FIG. 5 and FIG. 6A, secondary antenna portions 10 b and 10 c that overlap the left and right sides 100 b and 100 c of the built-in antenna 100 in the vertical direction may be provided integrally with the cover shell 4. In this case, the front edge of the portion of the top plate portion 4a where the notch 4b is provided is more than the rear side 100a of the built-in antenna 100 of the memory card MC in a state where the memory card MC is accommodated in the card accommodating portion 2b. The left and right side edges of the part located on the rear side and where the notch 4b is provided are located on the inner side of the left and right sides 100b and 100c of the built-in antenna 100, and the back side 100a of the built-in antenna 100 is Since the left and right sides 100b and 100c are covered with the secondary antenna portions 10b and 10c, the booster antenna plays a larger role with respect to the built-in antenna 100 than the socket 1 of FIG. And the reader / writer device can be further extended in communication distance.

また、図６（ｃ）に示すように内蔵アンテナ１００の後側の辺１００ａと左右の辺１００ｂ，１００ｃとにそれぞれ上下方向において重なり合う２次アンテナ部１０ａ，１０ｂ，１０ｃをカバーシェル４と一体に設けても良い。この場合、天板部４ａの切欠４ｂが設けられた部位の前縁は、カード収容部２ｂ内にメモリカードＭＣを収容した状態で、メモリカードＭＣの内蔵アンテナ１００の後側辺１００ａよりも前側に位置し、且つ、切欠４ｂが設けられた部位の左右の側縁は、内蔵アンテナ１００の左右の辺１００ｂ，１００ｃよりも内側に位置しており、内蔵アンテナ１００の後側辺１００ａと左右両側辺１００ｂ，１００ｃとがそれぞれ２次アンテナ部１０ａ，１０ｂ，１０ｃによって覆われているので、図１のソケット１に比べて、内蔵内蔵アンテナ１００に対するブースタアンテナの役割がより大きくなり、メモリカードＭＣとリーダライタ装置との間の通信距離をさらに延ばすことができる。   Further, as shown in FIG. 6C, the secondary antenna portions 10a, 10b, and 10c, which overlap the rear side 100a and the left and right sides 100b and 100c in the vertical direction, respectively, are integrated with the cover shell 4 as shown in FIG. It may be provided. In this case, the front edge of the portion of the top plate portion 4a where the notch 4b is provided is in front of the rear side 100a of the built-in antenna 100 of the memory card MC in a state where the memory card MC is accommodated in the card accommodation portion 2b. And the left and right side edges of the portion where the notch 4b is provided are located on the inner side of the left and right sides 100b and 100c of the built-in antenna 100. Since the sides 100b and 100c are covered by the secondary antenna portions 10a, 10b, and 10c, respectively, the booster antenna plays a larger role with respect to the built-in built-in antenna 100 than the socket 1 of FIG. The communication distance between the reader / writer device can be further extended.

ここで、２次アンテナ部の効果を検証するために、内蔵アンテナ１００と法線方向において重なる部位がないカバーシェル３を用い、２次アンテナ部をカバーシェル３と一体に形成する代わりに、２次アンテナ部の役割を果たす銅テープ２０（幅が約６ｍｍ）がカバーシェル３’に貼着されていない場合と、カバーシェル３’においてメモリカードＭＣの主平面（内蔵内蔵アンテナ１００が近接配置された側の主平面）に対向する面の所定位置に銅テープ２０を貼り付けた場合とで、リーダライタ装置との間の通信距離を測定した結果を以下の表１、表２に示す。なおこの場合は銅テープ２０とカバーシェル３’との間に粘着層が介在するため、銅テープ２０とカバーシェル３’とは電気的に絶縁されている。また表１，表２において上段のデータは、ケース２の上面のみが金属シェルで構成された本実施形態のソケット１（このようなソケット１をＡタイプと言う。）のデータであり、下段のデータは、ケース２の上面および下面が金属シェルで構成されたソケット１（このようなソケット１をＢタイプと言う。）のデータである。   Here, in order to verify the effect of the secondary antenna part, instead of forming the secondary antenna part integrally with the cover shell 3 using the cover shell 3 that does not overlap the internal antenna 100 in the normal direction, When the copper tape 20 (with a width of about 6 mm) serving as the next antenna portion is not attached to the cover shell 3 ′, the main plane of the memory card MC (the built-in built-in antenna 100 is disposed close to the cover shell 3 ′. Tables 1 and 2 below show the results of measuring the communication distance with the reader / writer device when the copper tape 20 is attached to a predetermined position on the surface facing the main plane on the other side. In this case, since the adhesive layer is interposed between the copper tape 20 and the cover shell 3 ′, the copper tape 20 and the cover shell 3 ′ are electrically insulated. The upper data in Tables 1 and 2 are data of the socket 1 of the present embodiment in which only the upper surface of the case 2 is formed of a metal shell (such socket 1 is referred to as A type). The data is data of a socket 1 in which the upper surface and the lower surface of the case 2 are formed of a metal shell (such a socket 1 is referred to as a B type).

表１中のデータａは、カードシェル３’に銅テープを貼り付けていない場合のデータを示しており、この場合、Ａタイプのソケット１では通信距離が６６ｍｍ、Ｂタイプのソケット１では通信距離が６２ｍｍであった。一方、表１のデータｂ〜ｅは、ロ字形の内蔵アンテナ１００の１つの辺に重なる部位に銅テープ２０を貼り付けた場合のデータであり、Ａタイプのソケット１では通信距離が７２〜７４ｍｍ、Ｂタイプのソケット１では通信距離が６７〜６９ｍｍとなっており、何れのタイプのソケットでも通信距離が延びている。   Data a in Table 1 indicates data when no copper tape is attached to the card shell 3 '. In this case, the communication distance is 66 mm for the A type socket 1 and the communication distance for the B type socket 1. Was 62 mm. On the other hand, data b to e in Table 1 are data when the copper tape 20 is attached to a portion overlapping one side of the square-shaped built-in antenna 100, and the communication distance is 72 to 74 mm in the A type socket 1. In the B type socket 1, the communication distance is 67 to 69 mm, and the communication distance is extended in any type of socket.

また表２のデータｆ，ｇは、内蔵アンテナ１００の２つの辺に重なる部位に銅テープ２０を貼り付けた場合のデータであり、Ａタイプのソケット１では通信距離が７６ｍｍ、Ｂタイプのソケット１では通信距離が６９〜７０ｍｍとなっており、何れのタイプのソケット１でも銅テープを貼り付けていない場合（データａ）や１つの辺に重なる部位のみに銅テープ２０を貼り付けた場合（データｂ〜ｅ）に比べて通信距離が延びている。   The data f and g in Table 2 are data when the copper tape 20 is attached to a portion overlapping the two sides of the built-in antenna 100. The communication distance is 76 mm for the A type socket 1, and the B type socket 1 is used. In the case where the communication distance is 69 to 70 mm, no copper tape is attached to any type of socket 1 (data a), or the copper tape 20 is attached only to a portion overlapping one side (data). The communication distance is extended compared with b to e).

また表２のデータｈ，ｉは、内蔵アンテナ１００の３つの辺に重なる部位に銅テープ２０を貼り付けた場合のデータであり、Ａタイプのソケット１では通信距離が７６〜７７ｍｍ、Ｂタイプのソケット１では通信距離が７１ｍｍとなっており、何れのタイプのソケット１でも銅テープを貼り付けていない場合（データａ）や、１つの辺又は２つの辺に重なる部位のみに銅テープ２０を貼り付けた場合（データｂ〜ｇ）に比べて通信距離が延びている。   The data h and i in Table 2 are data when the copper tape 20 is attached to a portion overlapping the three sides of the built-in antenna 100. In the A type socket 1, the communication distance is 76 to 77 mm, and the B type The socket 1 has a communication distance of 71 mm, and the copper tape 20 is attached only to a portion that overlaps one side or two sides when no copper tape is attached to any type of socket 1 (data a). The communication distance is extended as compared with the case (data b to g).

また更に表２のデータｊは、内蔵アンテナ１００の４辺全てに重なる部位に銅テープ２０を貼り付けた場合のデータであり、Ａタイプのソケット１では通信距離が７６ｍｍ、Ｂタイプのソケット１では通信距離が７０ｍｍとなっており、何れのタイプのソケット１でも銅テープを貼り付けていない場合（データａ）や、１つの辺に重なる部位のみに銅テープ２０を貼り付けた場合（データｂ〜ｇ）に比べて通信距離が延びている。なお２つの辺又は３つの辺に重なる部位に銅テープ２０を貼り付けた場合と比較すると通信距離は同程度であった。   Further, data j in Table 2 is data when the copper tape 20 is pasted on a portion that overlaps all four sides of the built-in antenna 100. The communication distance is 76 mm in the A type socket 1, and the data is in the B type socket 1. When the communication distance is 70 mm and no copper tape is attached to any type of socket 1 (data a), or when the copper tape 20 is attached only to a portion overlapping one side (data b to b) The communication distance is longer than that in g). In addition, compared with the case where the copper tape 20 was affixed on the part which overlaps two sides or three sides, the communication distance was comparable.
