Description

この発明は、アンテナ機能を有する非接触型ＩＣカード機能を備えた携帯無線機およびこの携帯無線機に用いられる電池に関する。   The present invention relates to a portable wireless device having a non-contact type IC card function having an antenna function and a battery used in the portable wireless device.

従来から電磁結合によりＩＣカードと外部読取装置との間で電力およびデータの送受信を行う非接触型ＩＣカードシステムが提案されている。
この非接触型ＩＣカードシステムに用いられるＩＣカードは、ＣＰＵやメモリ等のＩＣチップが搭載されるプリント基板の表面にアンテナとして機能する送受信用コイルが形成されている。
この送受信用コイル（以下、送受信用アンテナコイルと称す）に導体金属等が近接あるいは接触したりすると、導体金属上に渦電流が生じることが知られている。
導体金属上に生じた渦電流は、非接触型ＩＣカードと外部読取装置との間の電磁結合強度を弱めるため、非接触型ＩＣカードと外部読取装置間の送受信エラーを発生させる。 Conventionally, a non-contact type IC card system that transmits and receives power and data between an IC card and an external reader by electromagnetic coupling has been proposed.
In an IC card used in this non-contact type IC card system, a transmission / reception coil functioning as an antenna is formed on the surface of a printed board on which an IC chip such as a CPU or memory is mounted.
It is known that an eddy current is generated on a conductor metal when a conductor metal or the like approaches or comes in contact with the coil for transmission / reception (hereinafter referred to as an antenna coil for transmission / reception).
The eddy current generated on the conductive metal weakens the electromagnetic coupling strength between the non-contact type IC card and the external reader, and therefore causes a transmission / reception error between the non-contact type IC card and the external reader.

そのため、従来の非接触型ＩＣカードでは、例えば、特許文献１に示されているように、ＩＣチップあるいは送受信用アンテナコイルなどが実装されているプリント基板の裏面側（即ち、外部読取装置側の面）に、アモルファスなどのように透磁率および抵抗率の高い磁性体を接着または蒸着することが提案されている。
特開平８−１６７４５号公報（図１、段落０００９） Therefore, in the conventional non-contact type IC card, for example, as shown in Patent Document 1, the back side of the printed circuit board on which the IC chip or the antenna coil for transmission / reception is mounted (that is, the external reader side) It has been proposed to adhere or deposit a magnetic material having a high magnetic permeability and resistivity, such as amorphous, on the surface.
JP-A-8-16745 (FIG. 1, paragraph 0009)

ところで、非接触型ＩＣカード機能を有した携帯無線機では、携帯無線機本体に電力を供給する電池（例えば、二次電池）の近傍に送受信用アンテナコイルを実装配置せざるを得ないケースがある。
特に、最近主流となっている２つ折りタイプの携帯無線機では、上側筐体の内側にはメイン表示部があり、上側筐体の外側にはサブ表示部があるので、送受信用アンテナコイルが形成されたプリント基板を上側筐体の内側あるいは外側に配置するのは困難である。 By the way, in a portable wireless device having a non-contact type IC card function, there is a case where a transmitting / receiving antenna coil must be mounted and disposed in the vicinity of a battery (for example, a secondary battery) that supplies power to the portable wireless device body. is there.
In particular, in the two-fold type portable wireless devices that have recently become mainstream, there is a main display portion inside the upper housing and a sub display portion outside the upper housing, so that a transmission / reception antenna coil is formed. It is difficult to dispose the printed circuit board inside or outside the upper casing.

また、下側筐体の内側にはキー（操作用の押ボタン）があるので、やはり送受信用アンテナコイルを配置するのは困難である。
一方、下側筐体の外側には電池が配置されているが、表示部やキーなどの筐体表面に配置する必要のあるものがないため、下側筐体の外側は送受信用アンテナコイルの配置に最も適している。
そのため、２つ折りタイプの携帯無線機では、電池の近傍に送受信用アンテナコイルを配置せざるを得ない。 In addition, since there is a key (operation push button) inside the lower housing, it is difficult to arrange the transmitting / receiving antenna coil.
On the other hand, a battery is placed outside the lower housing, but there is nothing that needs to be placed on the housing surface, such as a display unit or a key. Most suitable for placement.
Therefore, in a two-fold type portable wireless device, a transmission / reception antenna coil must be disposed in the vicinity of the battery.

電池の発電要素（電池コアとも称す）は金属体（導体金属）であるため、送受信用アンテナコイルは金属体の近傍に配置されることになる。
前述したように、金属体の発電要素（電池コア）を含む電池の近傍に送受信用アンテナコイルが配置されると、金属体上に渦電流が生じて、送受信用アンテナコイルと外部読取装置との間の電磁結合強度が弱まり、外部読取装置との間の送受信エラーが発生する。 Since the power generation element (also referred to as battery core) of the battery is a metal body (conductor metal), the transmitting / receiving antenna coil is disposed in the vicinity of the metal body.
As described above, when the transmission / reception antenna coil is disposed in the vicinity of the battery including the power generation element (battery core) of the metal body, an eddy current is generated on the metal body, and the transmission / reception antenna coil and the external reader The electromagnetic coupling strength between the two becomes weak, and a transmission / reception error with the external reader occurs.

そのため、従来の非接触型ＩＣカードでは、ＩＣチップあるいは送受信用アンテナコイルなどが実装されているプリント基板の裏面側に、透磁率および抵抗率の高い別部材の磁性体を接着したり、蒸着によって透磁率および抵抗率の高い磁性体層を形成していたが、部品数あるいは作業工程が増加するため、製造コストが高くなるという問題点があった。
また、別部材の磁性体を接着したり、磁性体層を形成するので、薄型化・小型化が図れないとい問題点もあった。 Therefore, in the conventional non-contact type IC card, a magnetic material of another member having high magnetic permeability and resistivity is adhered to the back side of the printed circuit board on which the IC chip or the antenna coil for transmission / reception is mounted, or by vapor deposition. Although a magnetic layer having a high magnetic permeability and resistivity is formed, there is a problem that the manufacturing cost increases because the number of parts or work processes increases.
In addition, since a magnetic member as a separate member is bonded or a magnetic layer is formed, there is a problem that a reduction in thickness and size cannot be achieved.

この発明は、このような課題を解決するためになされたものであり、携帯無線機の送受信用アンテナコイルを電池に近接配置しても、渦電流の発生に起因する送信性能の劣化を防止できると共に、薄型化・小型化が図れる携帯無線機を提供することを目的とする。
また、このような携帯無線機に好適な電池を安価に提供することを目的とする。 The present invention has been made to solve such a problem, and even if the transmitting / receiving antenna coil of the portable wireless device is arranged close to the battery, it is possible to prevent the transmission performance from being deteriorated due to the generation of the eddy current. In addition, an object is to provide a portable wireless device that can be reduced in thickness and size.
It is another object of the present invention to provide a battery suitable for such a portable wireless device at low cost.
