Abstract
【解決手段】 無線用ICタグ25は、所望の誘電率を有する耐熱性のガラスエポキシ材からなる第2のスペーサ7aの表面及び裏面に、薄膜の金属アンテナを蒸着して第1のアンテナ3a及び第2のアンテナ8aを形成している。第1のアンテナ3aのほぼ中央部付近にはICチップ4が搭載されている。第2のアンテナ8aは、第1のアンテナ3aの発信電波の所望の周波数に共振して電波強度を強める補助アンテナの機能を備えている。したがって、ケーブルなどに実装しても、ケーブルの外被内に実装することができ、ケーブル内の金属部材によって第1のアンテナ3aの電波強度が弱まるおそれはない。
【選択図】 図7
Description
また、本発明の無線用ICタグによれば、ケーブル成形時の高温にも耐えることができるので、例えばケーブルの外被内に実装できる。これによってケーブルから脱落するおそれがなくなり、かつ、通信距離も長くすることができる。
<実施の形態1>
図4に、ICタグシステムの構成図を示す。ICタグシステムは、無線用ICタグと、この無線用ICタグとの間で所定の周波数の電波を送受信する外部アンテナ30、外部アンテナ30での電波の送受信を制御するリーダ31、リーダ31に対して無線用ICタグに記憶されたIDコードの読み取りを指示するホストコンピュータ32から構成される。また、リーダ31内のRF(Radio Frequency)送受信部311は、送受信する信号の入出力や変復調を行い、制御部312は、ホストコンピュータ32との通信やRF送受信部311との間での信号の入出力を行う。
<実施の形態2>
ただし、第2のアンテナ材14が第1のスペーサ材12や第2のスペーサ材13のように板状の材料であった場合には、後記するように、第1のスペーサ6、第2のスペーサ7を切断する際に同じ幅に切断されることになるので、位置検出器19を用いた送り出しタイミングの制御は不要となる。
また、切断において、4層構造のものを完全に切断してしまうと、切断後の後処理が煩雑となる(固定台22上で無線用ICタグがバラバラになる)ので、第2のアンテナ材14、第2のスペーサ材13、第1のアンテナ材11までは完全に切断し、一番下の層の第1のスペーサ材12についてはミシン目状に切断して、製造された各無線用ICタグが連なって固定台22上に並ぶようにすることが望ましい。
さらに、順次切断して無線用ICタグを製造していく際、その切断面には粘着面が露出することになるので、該粘着面に対してその粘着性を除去する処理、例えば、パウダーをふりかけるとともにその粉塵処理を行う等の処理が行われることになる。
次に、無線用ICタグを通信ケーブルや電力ケーブルなどの各種ケーブルに実装する場合の実施の形態について、従来技術と対比しながら本発明を説明する。図10は、従来技術において無線用ICタグをケーブルへ実装した状態を示す概念図であり、(a)は多芯ケーブルへの実装状態、(b)は単芯ケーブルへの実装状態を示している。図10(a)に示すように、通信ケーブルとして用いられる多芯ケーブル70は、それぞれ単芯外被71で覆われた内部導体72が多芯で形成されてシールド層73に覆われ、さらに外装がケーブル外被74で覆われている。そして、ケーブル外被74の表面に無線用ICタグ75が接着剤などによって貼り付けられている。
さらに、多芯ケーブル70や単芯ケーブル80の成形時にはケーブル外被74(または、ケーブル外被83)が高温になるため、製造工程中に無線用ICタグ75をケーブル外被74の内部に取付けると熱破壊を起こして取り付けることができない。そのため、製造工程終了後に無線用ICタグ75を貼付するための工程が追加されてしまうので、結果的にケーブルの製造コストが高くなってしまう。
さらに、図8(b)に示すように、電力ケーブルとして用いられる単芯ケーブル50は、内部導体51が単芯外被52に覆われ、さらに外装がケーブル外被53で覆われている。また、ケーブル外被53の内部には成形時に実装された無線用ICタグ25が埋め込まれている。このような無線用ICタグ25は、多芯ケーブル40や単芯ケーブル50の長さ方向に沿って例えば1m間隔で埋め込まれている。
これによって、熱破壊されることなく無線用ICタグ25をケーブル外被44またはケーブル外被53に取り付けることができるとともに、ケーブルを取り扱う際に無線用ICタグ25が多芯ケーブル40や単芯ケーブル50から剥がれ落ちるおそれはなくなる。
また、ケーブル外被に埋め込むための無線用ICタグとして、第2のスペーサにガラスエポキシを用いる例を挙げたが、これに限定されるものではなく、例えばセラミックやテフロン(登録商標)など耐熱性のある基板を第2のスペーサとして用いても本発明が実現されることはいうまでもない。
