Description

データ送受信するためICを有する電子回路とアンテナコイルをもったICタグに関し、データ送受信において送受信距離によって通信上の問題発生が潜在している。送受信においてデータ通信問題が発生しない最適通信感度を確保することが重要である。従がってICタグに入っている数多くのデータを送受信するためICタグと検出装置の距離に合致した感度調整が必要となる。本発明は、送受信感度調整を任意できる様にスリットを有した電磁波遮蔽板を組合せることによって安価に送受信感度を調整できるものである。感度調整のため金属板にスリットを入れるか、分割した形状の金属板を入れることによって送受信感度を調整し通信距離を任意に決めることの出来るICタグに関するものである。 With respect to an IC tag having an electronic circuit having an IC and an antenna coil for data transmission / reception, communication problems may occur depending on the transmission / reception distance in data transmission / reception. It is important to ensure optimal communication sensitivity that does not cause data communication problems in transmission and reception. Therefore, in order to transmit and receive a large amount of data contained in the IC tag, it is necessary to adjust the sensitivity in accordance with the distance between the IC tag and the detection device. The present invention can adjust the transmission / reception sensitivity at a low cost by combining an electromagnetic wave shielding plate having a slit so that the transmission / reception sensitivity can be arbitrarily adjusted. The present invention relates to an IC tag that can adjust a transmission distance by arbitrarily adjusting a transmission / reception sensitivity by inserting a slit in a metal plate for sensitivity adjustment or by inserting a divided metal plate.

送受信距離を任意に変える方法として、発信側の出力調整、または受信側の感度調整をすることにより可能であるが、いずれも送受信における信号到達感度はICタグ感度により個々に異なり感度一定にならない等の問題、更にICタグの感度が大きい場合には、近接する識別情報を感知してしまう等の問題が発生しやすい。 As a method of arbitrarily changing the transmission / reception distance, it is possible to adjust the output on the transmission side or the sensitivity adjustment on the reception side. In either case, the signal arrival sensitivity in transmission / reception differs depending on the IC tag sensitivity and does not become constant. In addition, when the sensitivity of the IC tag is high, problems such as sensing of adjacent identification information are likely to occur.

またICタグ感度調整をIC、アンテナで実施するにはICタグ設計時に行うことが必要で、完成後には感度調整できないと言う欠点を有していた。 In addition, in order to adjust the sensitivity of the IC tag with the IC and the antenna, it is necessary to perform it at the time of designing the IC tag, and there is a disadvantage that the sensitivity cannot be adjusted after completion.

例えば物品に付与されたICタグの確認を確実なものとするため、受発信電波到達距離を延長できるようにICタグと電気的に絶縁された補助アンテナを付加し、通信を確実にする方法が特許文献1に提案されている。 For example, in order to ensure the confirmation of the IC tag attached to the article, there is a method for ensuring communication by adding an auxiliary antenna that is electrically insulated from the IC tag so as to extend the arrival and reception radio wave arrival distance. This is proposed in Patent Document 1.

また複数個の物品を確認するために無線ICタグを物品に付与し、物品に関する情報と対応付けて蓄積する管理装置を有し、無線電波の強度によって無線ICタグの存在を確認する為の検知装置が特許文献2に提案されている。 In addition, a wireless IC tag is attached to an article in order to confirm a plurality of articles, and a management device that accumulates information associated with the article is stored to detect the presence of the wireless IC tag based on the intensity of the radio wave. An apparatus is proposed in Patent Document 2.

更に固定、移動物品の存在を検知する為に、物品に付与されたICタグの位置認識のための情報をメモリーに保存する手段を備えて位置確認する方法が特許文献3に提案されている。上記ICタグは情報確認のため、受発信電波到達距離を延長したり、ICタグ本体に情報をメモリーし、情報確認することによって位置認識をしている。本発明は複数個のICタグの信号を混信なく認識する為に、認識システムに合致した感度を確保するように感度調整するための金属製電磁波遮蔽板をもちいて、ICタグ用ユニットに装着し電波到達距離を制限し、複数個のICタグの通信に於ける混信防いだ事を特徴としたICタグを供給するものである。 Further, in order to detect the presence of a fixed and moving article, Patent Document 3 proposes a method for confirming the position by storing information for recognizing the position of an IC tag attached to the article in a memory. In order to confirm the information, the IC tag recognizes its position by extending the receiving / transmitting radio wave reaching distance, storing information in the IC tag main body, and confirming the information. The present invention uses a metal electromagnetic wave shielding plate for adjusting the sensitivity so as to ensure the sensitivity matching the recognition system in order to recognize the signals of a plurality of IC tags without interference, and is attached to the IC tag unit. The present invention provides an IC tag characterized by limiting radio wave reach and preventing interference in communication of a plurality of IC tags.

Accordingly, an object of the present invention is to provide an IC tag characterized in that an electromagnetic wave having a required strength can be obtained and information can be transmitted and received without interference.

更に金属製電磁波遮蔽板の材質を変える事によって感度調整範囲が広くなる。 Furthermore, the sensitivity adjustment range is widened by changing the material of the metallic electromagnetic shielding plate.
