Description

無線通信端末Wireless communication terminal
　本発明は、導電体を含む記録媒体を保持することが可能な無線通信端末に関し、特には、ＩＤカードとして用いる記録媒体を保持することが可能な無線通信端末に関する。 The present invention relates to a wireless communication terminal capable of holding a recording medium containing a conductor, and more particularly to a wireless communication terminal capable of holding a recording medium used as an ID card.
　現在、利用者が携帯可能なセンサ端末が普及している。古くから利用されているセンサ端末としては、万歩計が挙げられる。また、近年、携帯電話に加速度センサを搭載することで、携帯電話を万歩計と兼用することが可能になっている。さらに、スポーツ科学の分野では、利用者が携帯する心拍計なども開発されている。また、近年の無線技術の発達および普及に伴い、センサが測定したセンサ情報を無線通信でサーバに送信することが可能な無線センサ端末が開発されている。 Currently, sensor terminals that can be carried by users are widespread. An example of a sensor terminal that has been used for a long time is a pedometer. In recent years, an acceleration sensor is mounted on a mobile phone, so that the mobile phone can be used as a pedometer. Furthermore, in the field of sports science, heart rate monitors that are carried by users are also being developed. With the development and spread of wireless technology in recent years, wireless sensor terminals capable of transmitting sensor information measured by sensors to a server by wireless communication have been developed.
　また、社屋などの建物の中で利用者の氏名や身分などを示す手段として、利用者に関する情報（利用者の氏名、身分および顔写真など）が記載されたＩＤカードが利用されている。利用者は、ＩＤカードを携帯する場合、そのＩＤカードを胸に着けたり、ＩＤカードに紐を付け、その紐でＩＤカードを首から吊り下げたりする。 In addition, as a means for indicating a user's name and identity in a building such as a company building, an ID card in which information about the user (such as the user's name, identity, and facial photo) is used. When the user carries the ID card, the user wears the ID card on the chest or attaches a string to the ID card and hangs the ID card from the neck with the string.
　さらに、ＩＤカードを保持することが可能な無線センサ端末が開発されている。このような無線センサ端末としては、特許文献１に記載の通信装置がある。この通信装置は、赤外線センサと無線送信部とを備える。そして、通信装置は、ＩＤカードである社員証を保持するための社員証カードホルダーと兼用することが可能な形状になっている。 Furthermore, wireless sensor terminals that can hold ID cards have been developed. As such a wireless sensor terminal, there is a communication device described in Patent Document 1. The communication device includes an infrared sensor and a wireless transmission unit. The communication device has a shape that can also be used as an employee card card holder for holding an employee card, which is an ID card.
　また、従来、ＩＤカードは、紙やプラスチックなどで作られており、他の人間は、ＩＤカードを目視することで利用者に関する情報を確認していた。しかしながら、近年、記録媒体をＩＤカードとして用いることで、ＩＤカードを電子化することが可能になっている。例えば、磁気ストライプを有する記録媒体がＩＤカードとして使用され、その磁気ストライプに利用者に関する情報が記録される。また、ＩＣチップが内蔵された記録媒体がＩＤカードとして使用され、そのＩＣチップに利用者に関する情報が記録される。なお、ＩＣチップは、小型のコンピュータおよびメモリから構成される。 In addition, ID cards are conventionally made of paper or plastic, and other people have confirmed information about users by viewing the ID card. However, in recent years, it has become possible to digitize an ID card by using a recording medium as an ID card. For example, a recording medium having a magnetic stripe is used as an ID card, and information about the user is recorded on the magnetic stripe. In addition, a recording medium containing an IC chip is used as an ID card, and information about the user is recorded on the IC chip. The IC chip is composed of a small computer and a memory.
　さらに、ＩＣチップが内蔵された記録媒体として、非接触型ＩＣカードと呼ばれるものが開発されている。読み取り機は、非接触型ＩＣカードと物理的な接触がなくても、その非接触型ＩＣカード内の情報を読み書きすることが可能である。なお、非接触型ＩＣカードは、電磁波を送受するアンテナを内蔵しており、読み取り機は、電磁波を用いて非接触型ＩＣカードと無線通信を行うことで、非接触型ＩＣカードのＩＤチップ内の情報を読み書きしている。また、非接触型ＩＣカードは、外部からの電磁波を電力に変換し、その電力を蓄えることもできる。 Furthermore, what is called a non-contact type IC card has been developed as a recording medium incorporating an IC chip. The reader can read and write information in the non-contact type IC card without physical contact with the non-contact type IC card. Note that the non-contact type IC card has a built-in antenna for transmitting and receiving electromagnetic waves, and the reader performs wireless communication with the non-contact type IC card using the electromagnetic waves, so that the inside of the ID chip of the non-contact type IC card. Reading and writing information. The non-contact type IC card can also convert electromagnetic waves from the outside into electric power and store the electric power.
　非接触型ＩＣカードは、読み取り機との物理的な接触がなくてもよいため、利便性や耐久性が向上する。このため、非接触型ＩＣカードは、企業の社員証などとして急速に普及している。 ¡Non-contact IC cards do not have to be in physical contact with the reader, improving convenience and durability. For this reason, contactless IC cards are rapidly spreading as company employee ID cards.
　しかしながら、特許文献１に記載の通信装置のような、ＩＤカードを保持することが可能な無線センサ端末において、ＩＤカードとして、非接触型ＩＣカードが用いられると、以下の問題が生じる。つまり、非接触型ＩＣカードのアンテナが、ＩＤカードを保持する通信装置に覆われるため、非接触型ＩＣカードによる無線通信が可能な距離が減少するという問題が生じる。 However, in a wireless sensor terminal that can hold an ID card, such as the communication device described in Patent Document 1, if a non-contact type IC card is used as the ID card, the following problems occur. That is, since the antenna of the non-contact type IC card is covered with the communication device that holds the ID card, there arises a problem that the distance in which wireless communication by the non-contact type IC card can be performed decreases.
　特許文献２には、非接触型ＩＣカードによる無線通信が可能な距離の減少を抑制することができる携帯型情報機器が記載されている。この携帯型情報機器は、ＩＣカードを保持するＩＣカードホルダーを有する。また、ＩＣカードホルダーには、非接触型ＩＣカードのアンテナに対応する箇所に開口部が設けられている。このため、非接触型ＩＣカードのアンテナがＩＣカードホルダーに覆われることを防止することが可能になるため、非接触型ＩＣカードによる無線通信が可能な距離の減少を抑制することができる。
特開２００５－６１９３４号公報 特開２００２－１０９４８４号公報 Patent Document 2 describes a portable information device that can suppress a decrease in the distance in which wireless communication using a non-contact type IC card is possible. This portable information device has an IC card holder for holding an IC card. Further, the IC card holder is provided with an opening at a location corresponding to the antenna of the non-contact type IC card. For this reason, since it becomes possible to prevent the antenna of a non-contact type IC card from being covered with the IC card holder, it is possible to suppress a decrease in the distance in which wireless communication by the non-contact type IC card can be performed.

　一般的に、互いに無線通信を行う複数の無線通信機において、各無線通信機のアンテナの間に金属などの導電体が存在すると、無線通信が可能な距離が減少する。また、非接触型ＩＣカードは、アンテナやＩＣチップなどの電気回路を内蔵している。この電気回路は、導電体で作られている。 Generally, in a plurality of wireless communication devices that perform wireless communication with each other, if a conductor such as a metal exists between the antennas of each wireless communication device, the distance in which wireless communication is possible decreases. The non-contact type IC card incorporates an electric circuit such as an antenna or an IC chip. This electric circuit is made of a conductor.
　このため、無線センサ端末が非接触型ＩＣカードを保持しているときに、無線センサ端末のアンテナと無線アクセスポイントのアンテナとの間に、非接触型ＩＣカード内の電気回路が存在することになり、無線通信が可能な距離が減少するという問題が生じる。 For this reason, when the wireless sensor terminal holds the non-contact type IC card, an electric circuit in the non-contact type IC card exists between the antenna of the wireless sensor terminal and the antenna of the wireless access point. Thus, there arises a problem that the distance in which wireless communication is possible decreases.
　また、非接触型ＩＣカードの近傍に導電体がある場合には、非接触型ＩＣカードの性能劣化を防ぐために、一般的に、非接触ＩＣカードと導電体との間に磁性体で作られたシートが挟まれる。無線センサ端末のアンテナとサーバのアンテナとの間に、このような磁性体のシートが存在すると、無線通信が可能な距離が減少する可能性がある。 Also, when there is a conductor near the non-contact type IC card, it is generally made of a magnetic material between the non-contact type IC card and the conductor in order to prevent performance deterioration of the non-contact type IC card. A sheet is caught. If such a magnetic sheet exists between the antenna of the wireless sensor terminal and the antenna of the server, there is a possibility that the distance over which wireless communication can be performed decreases.
　さらには、ＩＤカードが他人から見えるように、ＩＤカードが胸などの人体の前面に保持されると、導電体を含むＩＤカードと人体との間に無線センサ端末のアンテナが挟まれることがある。この場合、人体が導電体であるため、無線センサ端末のアンテナとサーバのアンテナとの間に導電体が存在する確率が非常に高くなり、無線通信が可能な距離が減少する可能性が非常に高くなる。 Furthermore, when the ID card is held on the front side of the human body such as the chest so that the ID card can be seen by others, the antenna of the wireless sensor terminal may be sandwiched between the ID card including the conductor and the human body. . In this case, since the human body is a conductor, the probability that a conductor exists between the antenna of the wireless sensor terminal and the antenna of the server is very high, and the possibility that the wireless communication distance can be reduced is very high. Get higher.
　特許文献２に記載の発明では、ＩＤカードを保持する携帯型情報機器が無線通信を行うことは想定されていない。このため、ＩＤカードのアンテナに対応する箇所に開口部が設けられ、ＩＤカードによる無線通信が可能な距離の減少は抑制されているが、ＩＤカードが保持されたときに生じる携帯型情報機器による無線通信が可能な距離の減少については考慮されていない。 In the invention described in Patent Document 2, it is not assumed that a portable information device holding an ID card performs wireless communication. For this reason, although the opening part is provided in the location corresponding to the antenna of an ID card, the reduction | decrease of the distance which can communicate by radio | wireless by an ID card is suppressed, By the portable information device produced when an ID card is hold | maintained There is no consideration for a decrease in the distance over which wireless communication is possible.
　なお、上記の問題は、非接触型ＩＣカードだけでなく、電子回路などの導電体を含む一般的な記録媒体でも生じる。また、無線センサ端末だけでなく、無線通信を行う一般的な無線通信端末でも生じる。 Note that the above problem occurs not only in a non-contact type IC card but also in a general recording medium including a conductor such as an electronic circuit. Further, it occurs not only in a wireless sensor terminal but also in a general wireless communication terminal that performs wireless communication.
　本発明の目的は、上記の課題である、記録媒体が保持されているときに、無線通信が可能な距離が減少するという問題を解決する無線通信端末を提供することである。 An object of the present invention is to provide a wireless communication terminal that solves the above-described problem that the distance in which wireless communication is possible decreases when a recording medium is held.
　本発明による無線通信端末は、導電体を含む記録媒体を保持するための保持部と、前記保持部にて前記記録媒体が保持されているときに、該記録媒体で覆われない箇所に配置された、無線通信に用いるアンテナ部と、を含む。 A wireless communication terminal according to the present invention is disposed in a holding portion for holding a recording medium including a conductor, and a portion not covered with the recording medium when the recording medium is held by the holding portion. And an antenna unit used for wireless communication.
　本発明によれば、記録媒体が保持されているときに、無線通信が可能な距離が減少することを抑制することが可能になる。 According to the present invention, it is possible to suppress a decrease in the distance in which wireless communication is possible when the recording medium is held.

Note that the wireless communication unit 203 and the control unit 204 may be arranged at a place covered with the ID card 300 or may be arranged at a place not covered with the ID card 300.
　次に、無線センサ端末１０１の外形の一例について説明する。図４は、無線センサ端末１０１の外形の一例を示した斜視図である。 Next, an example of the outer shape of the wireless sensor terminal 101 will be described. FIG. 4 is a perspective view showing an example of the outer shape of the wireless sensor terminal 101.
　図４において、無線センサ端末１０１は、筺体４０１を含む。本体機能部２００は、筺体４０１に内蔵されている。また、筺体４０１の一つの面（前面）にＩＤカード保持部２１０が付けられている。 In FIG. 4, the wireless sensor terminal 101 includes a housing 401. The main body function unit 200 is built in the housing 401. An ID card holding unit 210 is attached to one surface (front surface) of the housing 401.
　ＩＤカード保持部２１０は、透明なシートで形成されている。ＩＤカード３００は、ＩＤカード保持部２１０と筺体４０１の間に挿入されることで保持される。 The ID card holding unit 210 is formed of a transparent sheet. The ID card 300 is held by being inserted between the ID card holding unit 210 and the housing 401.
　ＩＤカード保持部２１０の縦方向（図４のＸ方向）に関しては、特定の長さ以上のＩＤカードが挿入されることを防止できるようになっている。また、無線センサ端末１０１（筺体４０１）の縦方向（Ｘ方向）の長さは、ＩＤカード保持部２１０の縦方向（Ｘ方向）の長さより大きい。このため、ＩＤカード保持部２１０がＩＤカード３００を保持しているときでも、無線センサ端末１０１には、ＩＤカード３００と筺体４０１とが重ならない部分が形成される。 In the vertical direction of the ID card holding unit 210 (X direction in FIG. 4), it is possible to prevent an ID card having a specific length or more from being inserted. Further, the length of the wireless sensor terminal 101 (housing 401) in the vertical direction (X direction) is larger than the length of the ID card holding unit 210 in the vertical direction (X direction). Therefore, even when the ID card holding unit 210 holds the ID card 300, the wireless sensor terminal 101 is formed with a portion where the ID card 300 and the casing 401 do not overlap.
　無線アンテナ部２０１およびセンサ２０２は、ＩＤカード３００と重なっていない筺体４０１の部分の内部に配置される。これにより、無線アンテナ部２０１は、ＩＤカード３００で覆われていない箇所に配置されることになる。 The wireless antenna unit 201 and the sensor 202 are disposed inside the housing 401 that does not overlap the ID card 300. As a result, the wireless antenna unit 201 is arranged at a location not covered with the ID card 300.
　具体的には、無線アンテナ部２０１は、ＩＤカード３００と重なっていない、筺体４０１の点線で囲まれた部分（設置個所４０２）の内部に配置される。 Specifically, the wireless antenna unit 201 is disposed inside a portion (installation location 402) surrounded by a dotted line of the housing 401 that does not overlap the ID card 300.
　また、例えば、筺体４０１のＩＤカード保持部２１０が設けられた面の裏面（後面）には、安全ピンなどの不図示の止め具が設けられ、この止め具が使用されることにより、所有者の体の前面にＩＤカードが保持される。 In addition, for example, a stopper (not shown) such as a safety pin is provided on the back surface (rear surface) of the surface of the housing 401 on which the ID card holding unit 210 is provided. An ID card is held on the front of the body.
　センサ２０２は、無線センサ端末１０１のＩＤカード３００で覆われない箇所に設けられる。また、筺体４０１のセンサ２０２に対応する箇所には、筺体４０１にて検出対象が遮断されないように開口部が設けられている。 The sensor 202 is provided at a location not covered by the ID card 300 of the wireless sensor terminal 101. Further, an opening is provided at a location corresponding to the sensor 202 of the casing 401 so that the detection target is not blocked by the casing 401.
　なお、図４では、ＩＤカード３００の横方向（Ｙ方向）が無線センサ端末１０１の横方向（Ｙ方向）より長くても、ＩＤカード保持部２１０はＩＤカード３００を保持することが可能である。このとき、無線アンテナ部２０１およびセンサ２０２は、ＩＤカード３００で覆われない。したがって、本実施形態では、規格サイズは、ＩＤカードの横方向（Ｙ方向）の大きさに応じて決定されるものであり、ＩＤカードの縦方向（Ｘ方向）の大きさには依存しない。 In FIG. 4, the ID card holding unit 210 can hold the ID card 300 even when the horizontal direction (Y direction) of the ID card 300 is longer than the horizontal direction (Y direction) of the wireless sensor terminal 101. . At this time, the wireless antenna unit 201 and the sensor 202 are not covered with the ID card 300. Therefore, in this embodiment, the standard size is determined according to the size of the ID card in the horizontal direction (Y direction) and does not depend on the size of the ID card in the vertical direction (X direction).
　次に効果を説明する。 Next, the effect will be explained.
　本実施形態によれば、ＩＤカード保持部２１０は、特定の規格サイズのＩＤカードを保持する。無線アンテナ部２０１は、ＩＤカード保持部２１０にてＩＤカード３００が保持されているときに、ＩＤカード３００で覆われていない箇所に配置される。 According to the present embodiment, the ID card holding unit 210 holds an ID card having a specific standard size. When the ID card 300 is held by the ID card holding unit 210, the wireless antenna unit 201 is arranged at a location not covered by the ID card 300.
　この場合、ＩＤカード保持部２１０にてＩＤカード３００が保持されているときでも、無線アンテナ部２０１がＩＤカード３００で覆われないので、無線通信が可能な距離が減少することを抑制することが可能になる。 In this case, since the wireless antenna unit 201 is not covered with the ID card 300 even when the ID card 300 is held by the ID card holding unit 210, it is possible to suppress a decrease in the distance in which wireless communication is possible.

　この場合、ＩＤカード保持部２１０にてＩＤカード３００が保持されているときでも、無線アンテナ部２０１がＩＤカード３００で覆われないので、ＩＤカード３００でセンサの検出対象が遮断されることを抑制することが可能になる。したがって、センサ２０２の検出精度を向上させることが可能になる。 In this case, even when the ID card 300 is held by the ID card holding unit 210, the wireless antenna unit 201 is not covered by the ID card 300, so that the ID card 300 prevents the detection target of the sensor from being blocked. It becomes possible to do. Therefore, the detection accuracy of the sensor 202 can be improved.
　また、本実施形態では、センサは、赤外線センサである。この場合、ＩＤカードで赤外線が遮断されることを抑制することが可能になるので、赤外線センサの検出精度を向上させることが可能になる。 In the present embodiment, the sensor is an infrared sensor. In this case, since it is possible to suppress the infrared ray from being blocked by the ID card, the detection accuracy of the infrared sensor can be improved.
　また、本実施形態では、無線センサ端末１０１は、ＩＤカードを所有者の体の前面に保持させるためのＩＤカードホルダーを兼ねている。また、無線アンテナ部２０１は、ＩＤカードと所有者の体に挟まれない箇所に配置される。 In the present embodiment, the wireless sensor terminal 101 also serves as an ID card holder for holding the ID card on the front of the owner's body. In addition, the wireless antenna unit 201 is disposed at a location not sandwiched between the ID card and the owner's body.
　この場合、無縁アンテナ２０１と無線アクセスポイント１０４のアンテナとの間に人体が存在しなくなるので、無縁アンテナ２０１と無線アクセスポイント１０４のアンテナとの間に導電体が存在する確率を小さくすることが可能になる。したがって、無線通信が可能な距離が減少することをさらに抑制することが可能になる。 In this case, since no human body exists between the antenna 201 and the antenna of the wireless access point 104, it is possible to reduce the probability that a conductor exists between the antenna 201 and the antenna of the wireless access point 104. become. Therefore, it is possible to further suppress a decrease in the distance over which wireless communication is possible.
