Abstract

Even if IC tags adhered to the outer face of a physical distribution container or a pallet overlap each other, the transmissions to the IC tags can be satisfactorily performed to write and read data in and from the IC tags. Wireless IC tags (2, 3) are of the passive type including antennas (22, 32) formed on base sheets (21, 31) and IC chips (23, 33) mounted on the base sheets in a manner to conduct with the antennas (22, 32). When the surfaces of the two IC tags (2, 3) are overlapped in all directions, the antenna (22) is formed to have a pattern having no overlap with the antenna (32) of the partner IC tag. The IC tags (2, 3) are mounted on the outer faces of either a container for containing contents or a conveyer pallet for placing containers.

[0001] 本発明は、各種データの書き込みや読み出しを非接触で行う無線 ICタグに関し、 特に物流システムに用いられて製品や部品の検品を行うのに使用される無線 ICタグ に関する。  The present invention relates to a wireless IC tag that performs non-contact writing and reading of various data, and particularly relates to a wireless IC tag that is used in a logistics system and used to inspect products and parts.
背景技術  Background art
[0002] メーカーの物流センターや販売会社の物流センターでは、数多くの製品や部品等 を集配する必要があることから、種々の製品や部品等を収納するコンテナや段ボー ル箱等の物流用容器を用いており、この物流用容器に収納した状態で製品や部品 の出荷や納入を行っている。この場合、製品や部品を識別するためのバーコードが 個々の製品や部品に貼り付けられており、バーコードリーダーによって個々のバーコ ードの情報を読み取って検品を行って 、る。  [0002] Manufacturers 'distribution centers and distributors' distribution centers need to collect and deliver many products and parts. Therefore, containers for storing various products and parts, and containers for distribution such as cardboard boxes. The products and parts are shipped and delivered in the state of being stored in this distribution container. In this case, a barcode for identifying the product or part is affixed to each product or part, and the barcode reader reads the information of each bar code and inspects it.
[0003] し力しながら、バーコードを用いた検品では、検品担当者が製品や部品に付いてい るバーコードを個々に読み取る必要があり、検品作業に長時間を要しており、検品作 業の省力化を行うことができないものとなっている。これに対し、近年、 ICタグを物流 用容器の外面に貼り付け、 ICタグの情報をリーダー ·ライターによって読み取ることに より物流用容器内の製品や部品を検品することが行われている。  [0003] However, in the inspection using bar codes, it is necessary for the person in charge of inspection to individually read the barcodes attached to products and parts, and inspection work takes a long time. It is impossible to save labor. On the other hand, in recent years, products and parts in logistics containers have been inspected by attaching IC tags to the outer surface of logistics containers and reading information on IC tags with a reader / writer.
[0004] ICタグは、製品や部品の種類や個数に関する数多くの情報の書き込み及び読み 取りが可能である特徴を有しており、この特徴を利用することにより以下の検品システ ムが可能となる。すなわち、出荷側の物流センターでは、一の物流用容器に収納し た製品や部品の情報を ICタグに書き込んだ後、 ICタグをその物流用容器の外面に 貼り付けて出荷すると共に、 ICタグに書き込んだ情報を通信ネット等を介して納入側 の物流センターに送信する。納入側の物流センターでは、物流用容器を受け取った とき、物流用容器の外面に貼り付けられている ICタグを読み取り、読み取った情報が 事前に出荷側の物流センターから送信された情報と一致する力否かの照合を行う。 これにより、個々の製品や部品のバーコードを読み取ることなぐ物流用容器内の製 品や部品の検品を行うことができ、検品作業を効率的に行うことが可能となる。 [0004] The IC tag has a feature that can write and read a lot of information about the type and number of products and parts, and the following inspection system is possible by using this feature. . In other words, the distribution center on the shipping side writes information about products and parts stored in a single distribution container on an IC tag, and then attaches the IC tag to the outer surface of the distribution container before shipping. The information written in is sent to the distribution center on the delivery side via a communication network. When the distribution center receives the distribution container, it reads the IC tag attached to the outer surface of the distribution container, and the read information matches the information sent from the distribution center in advance. Check for power. This makes it possible to manufacture products in logistics containers without reading the barcodes of individual products and parts. Inspection of goods and parts can be performed, and inspection work can be performed efficiently.
[0005] 図 12及び図 13は、 ICタグを用いて上述の検品を行うための物流用容器 100、 110 をそれぞれ示す。物流用容器 100、 110は、いずれも容器本体 105、 115と、容器本 体 105, 115の外面に貼り付けられた ICタグ 200とを有して!/、る。  FIGS. 12 and 13 show distribution containers 100 and 110 for performing the above-described inspection using an IC tag, respectively. Each of the physical distribution containers 100 and 110 has a container main body 105 and 115 and an IC tag 200 attached to the outer surface of the container main body 105 and 115! /.
[0006] 容器本体 105, 115はいずれも折り畳みコンテナや段ボール箱力もなり、略直方体 に形成されている。製品や部品等はこの容器本体 105, 115の内部に収納される。 図 12に示す物流用容器 100では、容器本体 105の 4側面 101, 102, 103, 104の 外面に ICタグ 200力 S貝占り付けられるものであり、各側面 101, 102, 103, 104におけ る上部の中央部分に取り付けられている。図 13に示す物流用容器 110では、 4側面 111, 112, 113, 114のそれぞれの面中央咅分に ICタグ 200力取り付けられている 。このように ICタグ 200を容器本体 105, 115に取り付けることにより、容器本体 105, 115内に収納した製品や部品を個々に検品する作業が不要となる。ここで、物流用 容器 100, 110の検品に際しては、個々の容器本体 105, 115に取り付けた ICタグ 2 00の情報が全て同一であることの確認も行われるものである。  [0006] The container bodies 105 and 115 both have a folding container and a cardboard box force, and are formed in a substantially rectangular parallelepiped shape. Products, parts, and the like are stored in the container bodies 105 and 115. In the logistics container 100 shown in FIG. 12, the IC tag 200 force S shell is occupied on the outer surface of the four side surfaces 101, 102, 103, 104 of the container body 105, and each side surface 101, 102, 103, 104 is It is attached to the central part of the upper part. In the distribution container 110 shown in FIG. 13, 200 IC tags are attached to the central apportionment of each of the four side surfaces 111, 112, 113, and 114. By attaching the IC tag 200 to the container main bodies 105 and 115 in this way, the work of individually inspecting the products and parts stored in the container main bodies 105 and 115 becomes unnecessary. Here, when the physical distribution containers 100 and 110 are inspected, it is also confirmed that the information on the IC tags 200 attached to the individual container main bodies 105 and 115 are all the same.
[0007] これらの物流用容器 100, 110に用いられる ICタグ 200としては、特許文献 1に記 載されるように、無線によってデータの読み取り及び書き換えが可能な RAMタイプが 選択される。すなわちこのタイプでは、リーダー 'ライター力もの電波によって ICタグ 2 00のデータの書き換えが可能であると共に、 ICタグ 200からの電波を受信することに よってリーダ一.ライターを介して ICタグ 200内のデータの読み取りが可能となるもの であり、繰り返し使用が可能な点で経済的となっている。  [0007] As described in Patent Document 1, a RAM type capable of wirelessly reading and rewriting data is selected as the IC tag 200 used for these physical distribution containers 100 and 110. In other words, in this type, the data of the IC tag 200 can be rewritten by the radio wave of the reader's writer power, and the radio wave in the IC tag 200 is received via the reader / writer by receiving the radio wave from the IC tag 200. Data can be read and is economical in that it can be used repeatedly.

発明が解決しょうとする課題  Problems to be solved by the invention
[0008] 図 12及び図 13のような ICタグ 200の取り付け位置では、複数の物流用容器を並べ たときに、 ICタグ 200との送受信ができなくなる或いは送受信が難しくなる問題を有し ている。図 14はこれを図 10に示す物流用容器 100に関して説明するものである。 [0008] At the attachment position of the IC tag 200 as shown in FIG. 12 and FIG. 13, when a plurality of distribution containers are arranged, there is a problem that transmission / reception with the IC tag 200 becomes impossible or transmission / reception becomes difficult. . FIG. 14 illustrates this with respect to the physical distribution container 100 shown in FIG.
[0009] 物流用容器は運搬や格納の効率や作業のし易さから同じ形状及び同じ寸法のも のを用いることが取り引きの常となっており、又、 ICタグも物流用容器の種別に合わ せて略同じ箇所に取り付けられることが取り引きの常となっている。従って、図 12の物 流用容器 100の場合は、その複数を同時に用いて出荷や搬入が行われる。これらの 出荷や搬入の際の検品においては、複数の物流用容器 100を横並びさせることが行 われる。 [0009] For logistics containers, it is usual to use products with the same shape and dimensions because of the efficiency of transportation and storage and ease of work, and IC tags are also classified as types of logistics containers. Together It is common for transactions to be attached to approximately the same location. Accordingly, in the case of the distribution container 100 of FIG. 12, shipment and delivery are performed using a plurality of the containers at the same time. In the inspection at the time of shipment or delivery, a plurality of distribution containers 100 are arranged side by side.
[0010] すなわち、図 14における左側に積み重ねられている物流用容器 100、 100と、右 側に積み重ねられている物流用容器 100、 100とは、矢印 Aで示すように、左側の物 流用容器 100の側面 101と、これと対面する左側の物流用容器 100の側面 103とが 突き合わせられるように横並び状態に整列させられる。すなわち、一の物流用容器 1 00における容器本体 103は、他の容器本体 103と上下 '前後'左右の向きが全て同 じとなるように整列させられる。  [0010] That is, the distribution containers 100, 100 stacked on the left side in FIG. 14 and the distribution containers 100, 100 stacked on the right side are, as shown by arrow A, the left distribution container. The side surface 101 of the 100 and the side surface 103 of the left logistics container 100 facing the side surface 101 are aligned side by side so as to face each other. In other words, the container main body 103 in one physical distribution container 100 is aligned with the other container main body 103 so that all of the vertical and longitudinal directions are the same.
[0011] このように対応した側面 101と対面している側面 103とが突き合わせられた場合、 側面 101と側面 103とに取り付けられた ICタグ 200の表面が相互に重なった状態と なる。すなわち、ノ、ツチングで示す ICタグ 200の表面が相互に重なった状態となるも のである。そして、このように ICタグ 200の表面が重なり合うことにより、 ICタグ 200が 相互に被さった状態となるため、交信の電波が到達しにくくなるば力りでなぐ発信し にくくなる。このため、 ICタグ 200の送受信が難しくなるものである。  When the corresponding side surface 101 and the side surface 103 facing each other are brought into contact with each other in this way, the surfaces of the IC tags 200 attached to the side surface 101 and the side surface 103 are overlapped with each other. In other words, the surfaces of the IC tags 200 indicated by “no” and “tuching” are in a state of overlapping each other. Since the surfaces of the IC tags 200 overlap in this way, the IC tags 200 are covered with each other, so that if the radio waves of communication are difficult to reach, it is difficult to transmit with force. For this reason, transmission / reception of the IC tag 200 becomes difficult.
[0012] 以上のような ICタグ 200の重なり合 、は、物流用容器 100、 110が載置されるパレ ットにおいても同様な問題となっている。図 15はこれを示すものであり、パレット 300 は物流用容器等の容器(図示省略)が載置されるパレット体 305を有しており、このパ レット体 305の外面に ICタグ 200が貼り付けにより取り付けられる。  The overlapping of the IC tags 200 as described above is a similar problem in the pallet on which the physical distribution containers 100 and 110 are placed. FIG. 15 shows this, and the pallet 300 has a pallet body 305 on which a container such as a distribution container (not shown) is placed, and the IC tag 200 is attached to the outer surface of the pallet body 305. It is attached by attaching.
[0013] パレット体 305は桁部 306、 307を左右部分及び中央部分に有し、これらの桁部 30 6, 307の上下部分に上側面板 310及び下側面板 320が設けられた扁平な立方体 形状に成形されている。この場合、パレット 300は運搬や格納の効率や作業のし易さ 力も大きさがある程度規格化されており、し力も出荷や搬入の際には作業のし易さか ら横並びが可能なように略同じ大きさのものが使用される。 ICタグ 200は一のパレット 体 305の外面に複数が貼り付けられるものであり、貼り付け作業性を考慮してパレット 体 305における中央部分の桁部 307の外面に貼り付けられる。  [0013] The pallet body 305 has flat portions having spar portions 306 and 307 in the left and right portions and the central portion, and upper and lower side plates 310 and 320 provided on the top and bottom portions of these spar portions 30 and 307. It is molded into. In this case, the pallet 300 has been standardized to some extent in terms of efficiency of transport and storage and ease of work, and the force is abbreviated so that it can be lined up for ease of work when shipping or loading. The same size is used. A plurality of IC tags 200 are pasted on the outer surface of one pallet body 305, and are pasted on the outer surface of the girder 307 at the center of the pallet body 305 in consideration of pasting workability.
[0014] このような条件において、左側のパレット 300及び右側のパレット 300は矢印 Aで示 すように、左側のパレット 300の側面と、これと対面する右側のパレット 300の側面と が突き合わせられるように横並び状態で整列させられる。このように対面して 、る側 面と側面とが突き合わせられた場合、それぞれのパレット体 305の中央部分の桁部 3 07に貼り付けられた ICタグ 200の表面が相互に重なった状態となる。図 15にお ヽて は、ノ、ツチングを施した ICタグ 200が相互に重なった状態となる。従って、この場合に おいても、図 12に示す物流用容器 100の場合と同様に交信用電波が到達しに《な るばかりでなぐ発信しに《なり、 ICタグ 200の送受信が難しくなる問題を有している [0014] Under these conditions, the left pallet 300 and the right pallet 300 are indicated by arrows A. In this way, the side surfaces of the left pallet 300 and the side surfaces of the right pallet 300 facing each other are aligned in a side-by-side state. In this way, when the side and the side face each other, the surfaces of the IC tags 200 attached to the girders 3 07 at the center of each pallet body 305 are overlapped with each other. . In FIG. 15, the IC tags 200 that have been glued and glued overlap each other. Therefore, in this case as well, as in the case of the distribution container 100 shown in FIG. 12, the communication radio wave arrives and becomes a transmission, and it becomes difficult to send and receive the IC tag 200. have
[0015] 図 15は、以上の物流用容器 100, 110やパレット 300の外面に貼り付けられる ICタ グ 200を示す。 ICタグ 200は、薄いベースシート 210上に ICチップ 220と、 ICチップ 220に接続されたアンテナ 230とを有している。アンテナ 230は導電性金属の印刷に より形成される。この ICタグ 200はベースシート 210の全面に粘着剤が塗布されてお り、剥離紙 240を剥がした後、粘着面を介して貼り付けを行う。 FIG. 15 shows an IC tag 200 that is affixed to the outer surfaces of the above distribution containers 100 and 110 and the pallet 300. The IC tag 200 has an IC chip 220 on a thin base sheet 210 and an antenna 230 connected to the IC chip 220. The antenna 230 is formed by printing a conductive metal. The IC tag 200 has an adhesive applied to the entire surface of the base sheet 210. After the release paper 240 is peeled off, the IC tag 200 is pasted through the adhesive surface.
[0016] アンテナ 230は、 ICチップ 220を中心にして略左右対称となった形状に形成されて いる。従って、 ICタグ 200の表面が他の ICタグ 200の表面と重なり合うと、アンテナ 2 30のほとんどの部分も相互に重なり合った状態となる。これにより、上述したアンテナ 230を介した送受信が難しくなるものである。  The antenna 230 is formed in a shape that is substantially symmetrical with respect to the IC chip 220. Therefore, when the surface of the IC tag 200 overlaps the surface of another IC tag 200, most of the antennas 230 also overlap each other. As a result, transmission / reception through the antenna 230 described above becomes difficult.
[0017] 本発明は、このような従来の問題点を考慮してなされたものであり、物流用容器や パレットの外面に貼り付けられた ICタグが重なり合っても、 ICタグへの送受信を良好 に行うことができ、これにより、データの書き込みやデータの読み取りを行うことが可能 な無線 ICタグを提供することを目的とする。  [0017] The present invention has been made in consideration of such conventional problems, and even when IC tags attached to the outer surface of a distribution container or a pallet overlap, transmission / reception to / from the IC tag is good. The purpose of this is to provide a wireless IC tag that can write data and read data.

[0026] 以下、本発明を図示する実施形態により具体的に説明する。なお、各実施形態に おいて、同一の部材には同一の符号を付して対応させてある。  Hereinafter, the present invention will be described in detail with reference to embodiments illustrated in the drawings. In each embodiment, the same members are assigned the same reference numerals.
[0027] 図 1及び図 2は、本発明の無線 ICタグの第 1実施形態を示す。図 1に示すように、一 方の無線 ICタグ 2と、他方の無線 ICタグ 3とを備えている。それぞれの無線 ICタグ (以 下、 ICタグと記載する。) 2, 3は、いずれも正面が矩形状或いは正方形状となってい る薄いベースシート 21, 31と、ベースシート 21, 31の片面上に形成されたそれぞれ 2本のアンテナ 22, 32と、アンテナ 22, 32と接続された ICチップ 23, 33とを備えて いる。  1 and 2 show a first embodiment of the wireless IC tag of the present invention. As shown in FIG. 1, one wireless IC tag 2 and the other wireless IC tag 3 are provided. Each wireless IC tag (hereinafter referred to as “IC tag”) 2 and 3 is a thin base sheet 21, 31 whose front is rectangular or square, and on one side of the base sheets 21, 31. Each having two antennas 22 and 32 and IC chips 23 and 33 connected to the antennas 22 and 32, respectively.
[0028] ベースシート 21, 31はポリオレフイン、ポリエステル、ポリイミド、その他の榭脂フィル ム或いは紙材が使用される。アンテナ 22, 32はこのベースシート 21, 31上に Al、Ag 、 Au、 Cu等の導電性金属を印刷することにより形成される。また、蒸着やスパッタリン グ等によって導電性金属の薄膜をベースシート 21, 31の全面に積層したり、導電性 金属の薄膜をベースシート 21, 31の全面に貼り付け、その後にエッチングを施して 図示した所定のパターンのアンテナを形成することができる。 ICチップ 23, 33はそれ ぞれのアンテナ 22, 32におけるチップ実装部位に導電性接着剤を介して固定する ことにより取り付けられる。この実施形態において、それぞれの ICタグ 2, 3はベースシ ート 21, 31の略中央部分に ICチップ 23, 33が設けられている。なお、 ICタグ 2, 3の ベースシート 210の全面には粘着剤が塗布されており、剥離紙 240を剥がした後、粘 着面を容器やパレットの外面に押し当てることにより ICタグ 2, 3が容器やパレットの外 面に貼り付けられる。 [0028] The base sheets 21 and 31 are made of polyolefin, polyester, polyimide, other resin films or paper materials. The antennas 22 and 32 are formed by printing conductive metals such as Al, Ag, Au, and Cu on the base sheets 21 and 31. Also, a conductive metal thin film is laminated on the entire surface of the base sheets 21, 31 by vapor deposition or sputtering, etc., or a conductive metal thin film is applied to the entire surface of the base sheets 21, 31 and then etched. An antenna having a predetermined pattern shown in the figure can be formed. The IC chips 23 and 33 are attached by being fixed to the chip mounting portions of the respective antennas 22 and 32 through a conductive adhesive. In this embodiment, each of the IC tags 2 and 3 is provided with IC chips 23 and 33 at a substantially central portion of the base sheets 21 and 31. Note that an adhesive is applied to the entire surface of the base sheet 210 of the IC tags 2 and 3, and after peeling the release paper 240, the adhesive surface is pressed against the outer surface of the container or pallet. Is affixed to the outside of the container or pallet.
[0029] 本発明において、 ICタグ 2, 3として、パッシブ型の ICタグを用いるものである。パッ シブ型の ICタグは電池を有していないため、通常は動作することがない。この状態に 対し、リーダー 'ライター側のアンテナが ICタグに対して電波を送信することにより、 I Cタグはその電波を ICチップの電源生成部の整流回路に送って直流に変換し、この 直流をエネルギーとして作動する。このようなパッシブ型の ICタグを用いることにより、 電池を実装する必要がないため長期間繰り返し使用することができるメリットがある。  In the present invention, passive IC tags are used as the IC tags 2 and 3. Passive IC tags do not have a battery and do not normally operate. In response to this, the antenna on the reader / writer side transmits radio waves to the IC tag, and the IC tag sends the radio waves to the rectifier circuit of the power generation part of the IC chip and converts it to direct current. Operates as energy. By using such a passive IC tag, there is an advantage that it can be used repeatedly for a long time because it is not necessary to mount a battery.
[0030] 図 2はパッシブ型 ICチップの内部構造を示し、この実施形態の ICタグ 2, 3及びそ の他の実施形態の ICタグに適用されるものである。 ICタグはアンテナ 60と ICチップ 6 1とを有して 、る。 ICチップ 61はアンテナ 60を介して受信した信号を復調する復調 部 62と、送信用データを変調した変調信号をアンテナ 60に出力する変調部 63と、 データが書き込まれるメモリ部 64と、復調したデータをメモリ部 64に書き込んだり、メ モリ部 64内のデータを読み出す制御部 65とを有している。さらに、アンテナ 60に流 れる電流を整流して電源を生成する電源生成部 66を備えており、電源生成部 66が 生成した電源によって復調部 62,変調部 63、制御部 65が作動する。  FIG. 2 shows the internal structure of the passive IC chip, which is applied to the IC tags 2 and 3 of this embodiment and the IC tags of other embodiments. The IC tag has an antenna 60 and an IC chip 61. The IC chip 61 demodulates a demodulator 62 that demodulates a signal received via the antenna 60, a modulator 63 that outputs a modulated signal obtained by modulating transmission data to the antenna 60, a memory unit 64 in which data is written, and a demodulator 62. It has a control unit 65 that writes data into the memory unit 64 and reads out data in the memory unit 64. Furthermore, a power generation unit 66 that generates power by rectifying the current flowing through the antenna 60 is provided, and the demodulation unit 62, the modulation unit 63, and the control unit 65 are operated by the power generated by the power generation unit 66.
[0031] 本発明において、 2つの ICタグ 2, 3は物流用容器 100, 110の外面における図 12 、図 13に示す位置や、パレット 300の外面における図 15に示す位置に貼り付けられ る。従って、製品や部品の検品のために物流用容器 100やパレット 300を横並び状 に整列させた場合には、図 14及び図 15に示すように、対面した箇所の ICタグが相 互に重なり合う。このような ICタグ 2, 3の重なり合いがあった場合においても、一の IC タグ 2のアンテナ 22と他の ICタグ 3のアンテナ 32とが相互に重ならないように形成さ れるものである。以下、これを図 1により説明する。 [0032] 図 1は 2つの ICタグ 2, 3を正面(表面)から見た状態であり、同図にお 、て、符号 Z は 2つの ICタグ 2, 3を線対称位置に配置した時の線対称軸 (対称軸)である。従って 、この線対称軸 Zに沿って折り曲げることにより、 ICタグ 2, 3は上下及び左右の方向 が同じとなり、この状態で表面が相互に重なり合うため、物流用容器やパレットを横並 び状に整列させたときと同様な重なり合いとなる。 In the present invention, the two IC tags 2 and 3 are attached to the positions shown in FIGS. 12 and 13 on the outer surface of the physical distribution containers 100 and 110 and the positions shown in FIG. 15 on the outer surface of the pallet 300. Therefore, when logistics containers 100 and pallets 300 are aligned side by side for inspection of products and parts, as shown in FIG. 14 and FIG. 15, the IC tags at the facing locations overlap each other. Even when the IC tags 2 and 3 are overlapped, the antenna 22 of one IC tag 2 and the antenna 32 of another IC tag 3 are formed so as not to overlap each other. This will be described below with reference to FIG. [0032] Fig. 1 shows the two IC tags 2 and 3 viewed from the front (front surface). In the figure, the symbol Z indicates when the two IC tags 2 and 3 are arranged in line-symmetric positions. The line symmetry axis (symmetry axis). Therefore, by folding along the axis of symmetry Z, the IC tags 2 and 3 have the same vertical and horizontal directions, and the surfaces overlap each other in this state, so that distribution containers and pallets are arranged side by side. The overlap is the same as when aligned.
[0033] ここで、一方(左側)の ICタグ 2において、そのアンテナ 22のパターンは左端部が高 ぐこの左端部力も右側に向力つて直線的に低くなるように形成されている。これに対 し、他方 (右側)の ICタグ 3のアンテナ 32のパターンは実線で示すように、水平な横 方向に延びるように形成されている。このように形成することにより、 2つのアンテナ 22 , 32は線対称軸 Zに対して非対称となる。この状態では、 2つの ICタグ 2, 3の表面を 重ね合わせても、 2つの ICタグ 2, 3のアンテナ 22, 32が重なり合うことがない。従つ て、アンテナ 22, 32の送信や受信に支障が生じることがなぐ ICタグ 2, 3へのデータ の書き込みやデータの読み取りを行うことができ、安定した送受信を行うことができる 。これにより、製品や部品の検品を確実に行うことができる。  [0033] Here, in one (left side) IC tag 2, the pattern of the antenna 22 is formed such that the left end portion is high, and the left end portion force is also linearly lowered as it is directed to the right side. On the other hand, the pattern of the antenna 32 of the other (right side) IC tag 3 is formed so as to extend in the horizontal horizontal direction as shown by the solid line. By forming in this way, the two antennas 22 and 32 are asymmetric with respect to the line symmetry axis Z. In this state, even if the surfaces of the two IC tags 2 and 3 are overlapped, the antennas 22 and 32 of the two IC tags 2 and 3 do not overlap. Therefore, data can be written to and read from the IC tags 2 and 3 without causing any trouble in transmission and reception of the antennas 22 and 32, and stable transmission and reception can be performed. Thereby, inspection of a product or a part can be performed reliably.
[0034] なお、図 1にお!/、ては、鎖線 32aのパターンで示すように、他方の ICタグ 3のアンテ ナを上下方向に配置しても、一方の ICタグ 2のアンテナ 22とは非対称であり、アンテ ナ 22と重なり合うことがない。このため、上記と同様に安定した送受信を行うことがで きる。以上のように 2つの ICタグ 2, 3の表面を重ね合わせる場合に、これらのアンテ ナ 22, 32が相互に重なり合うことのない配置は任意に設定できるものである。これに 対し、鎖線 32cのパターンで示すように、他方のアンテナを一方の ICタグ 2のアンテ ナ 22との線対称位置に形成した場合には、アンテナ 22, 32cが相互に重なり合うこと となり、電波の交信ができないか、交信しに《なり、データの送受信が難しくなる。  [0034] In FIG. 1, as shown by the pattern of chain line 32a, even if the antenna of the other IC tag 3 is arranged in the vertical direction, the antenna 22 of one IC tag 2 Is asymmetric and does not overlap with antenna 22. Therefore, stable transmission / reception can be performed as described above. As described above, when the surfaces of the two IC tags 2 and 3 are overlapped, the arrangement in which the antennas 22 and 32 do not overlap each other can be arbitrarily set. On the other hand, when the other antenna is formed in a line symmetrical position with the antenna 22 of one IC tag 2 as shown by the pattern of the chain line 32c, the antennas 22 and 32c overlap each other, and the radio wave It is difficult to exchange data, or it becomes difficult to communicate, making it difficult to send and receive data.
[0035] 本発明にお!/、て、 ICタグ 2, 3として UHF帯 ICタグを用いるものである。 UHF帯 IC タグは UHF帯域を通信周波数帯域として無線方式で通信を行うタグであり、周波数 が低いと共に空間での減衰が小さぐ電磁誘導を用いる 135KHZ未満の帯域や 13. 56MHz帯域を通信周波数帯域として使用する ICタグ、さらには無線方式で通信を 行う 2. 45GHz帯 ICタグに比べて通信距離が 3〜: LOmと長い特徴を有している。こ れにより、販売会社の物流センター 82 (図 11参照)での検品構造を簡単にすることが できる。 In the present invention, UHF band IC tags are used as the IC tags 2 and 3. The UHF band IC tag is a tag that performs radio communication using the UHF band as the communication frequency band, and uses electromagnetic induction that uses low frequency and small attenuation in space, and the band below 135KHZ and 13.56MHz band is the communication frequency band. IC tag used as a wireless communication system, and wireless communication 2. Compared with 45GHz band IC tag, communication distance is 3 ~: LOm longer. This simplifies the inspection structure at the distribution center 82 of the sales company (see Fig. 11). it can.
[0036] 図 10は本発明の ICタグが適用される物流システムの一例を示す。この物流システ ムは、販売会社とメーカーとの間で構築されるシステムである。販売会社は製品や部 品の管理を行う管理センター 81と、物流センター 82と、製品や部品を行う販売店 83 とを有している。メーカー 84は、販売店 83の管理センター 81と連絡が行われるように 接続されていると共に、販売会社の物流センター 82に対し、製品や部品の搬入を行 う物流センター 85を有している。製品や部品の搬入は、物流用容器 1内に製品や部 品を収納し、この物流用容器 1を販売会社の物流センター 82に搬送することにより行 われる。この場合、物流用容器 1の外面には、本発明の ICタグ 50を貼り付けて販売 会社を物流センター 82に搬送する。  FIG. 10 shows an example of a physical distribution system to which the IC tag of the present invention is applied. This logistics system is a system built between sales companies and manufacturers. The sales company has a management center 81 for managing products and parts, a distribution center 82, and a dealer 83 for products and parts. The manufacturer 84 is connected so as to be in contact with the management center 81 of the dealer 83, and has a distribution center 85 for carrying products and parts to the distribution center 82 of the sales company. Products and parts are brought in by storing products and parts in the distribution container 1 and transporting the distribution container 1 to the distribution center 82 of the sales company. In this case, the IC tag 50 of the present invention is attached to the outer surface of the distribution container 1, and the sales company is conveyed to the distribution center 82.
[0037] 販売会社の管理センター 81は製品や部品の在庫及び販売を管理する在庫 Z販 売管理部 87及び ICタグ 50の情報を管理する ICタグ情報管理部 88を有している。  [0037] The management center 81 of the sales company has an inventory Z sales management unit 87 that manages the inventory and sales of products and parts, and an IC tag information management unit 88 that manages information on the IC tag 50.
[0038] 図 10に示す物流システムにおいては、販売会社の販売店 83が管理センター 81に 対して発注 Bを行う。この発注 Bにより在庫 Z販売管理部 87は、メーカーに対してそ の旨の発注 Cを行う。発注 Cがあったときメーカー 84はその物流センター 85に対して 出荷指示 Dを行う。  In the physical distribution system shown in FIG. 10, a sales company 83 of the sales company places an order B with the management center 81. With this order B, the inventory Z sales management unit 87 places an order C to that effect to the manufacturer. When order C is received, manufacturer 84 issues a shipping instruction D to distribution center 85.
[0039] 出荷指示 Dを受けたメーカーの物流センター 85は、出荷指示 Dに応じた出荷デー タ Eを管理センター 81の在庫 Z販売管理部 87にネット等を介して送信する。出荷デ ータ Eは、事前出荷情報と ICタグ 50に書き込む製品、部品の情報とを対応させたデ ータとなっている。在庫 Z販売管理部 87は、受信した出荷データ Eを ICタグ情報管 理部 88に送信する。  Upon receiving the shipping instruction D, the manufacturer's distribution center 85 transmits the shipping data E corresponding to the shipping instruction D to the inventory Z sales management unit 87 of the management center 81 via the network or the like. Shipment data E is data in which advance shipment information is associated with information on products and parts written to the IC tag 50. The inventory Z sales management unit 87 transmits the received shipping data E to the IC tag information management unit 88.
[0040] その後、メーカーの物流用容器 85から物流用容器 1を販売会社の物流センター 82 に搬送する。販売会社の物流センター 82では、物流用容器 1に貼り付けられている I Cタグ 50をリーダー 'ライター(図 11参照)によって読み取って検品を行う。この検品 データ Fを ICタグ情報管理部 88に送信する。 ICタグ情報管理部 88では、この ICタグ 50から読み取った検品データ Fと、上述した出荷データ Eとを照合する。  [0040] Thereafter, the distribution container 1 is transported from the manufacturer's distribution container 85 to the distribution center 82 of the sales company. At the distribution center 82 of the sales company, the IC tag 50 affixed to the distribution container 1 is read by a reader / writer (see Fig. 11) for inspection. This inspection data F is transmitted to the IC tag information management unit 88. The IC tag information management unit 88 collates the inspection data F read from the IC tag 50 with the shipping data E described above.
[0041] 照合の結果、出荷データ Eと検品データ Fとが一致している場合には、その物流用 容器 1内に収納されて 、る製品や部品が正 、と判断し、その照合結果 Gを販売会 社の物流センター 82に返信する。照合結果 Gの返信を受けた販売会社の物流セン ター 82は、その物流用容器 1をそのまま販売店 83に対して搬入する。このような物流 システムでは、物流用容器 1ごとに対して検品を行って照合するため、物流用容器 1 内に収納した製品や部品ごとの検品を行う必要がなぐ検品作業を円滑に行うことが できる。なお、本発明では、物流用容器 1だけでなぐ物流用容器 1を搬送するパレツ トにも適用できるものであり、このため、 ICタグ 50がパレットの外面に貼り付けられる。 [0041] If the shipping data E and the inspection data F match as a result of the verification, it is determined that the product or part stored in the distribution container 1 is correct, and the verification result G Sales party Reply to company logistics center 82. The distribution center 82 of the sales company that received the reply of the verification result G carries the distribution container 1 to the sales store 83 as it is. In such a distribution system, inspection is performed for each distribution container 1 and collation is performed. Therefore, it is possible to smoothly perform inspection work that does not require inspection for each product or part stored in the distribution container 1. it can. In the present invention, the present invention can be applied to a pallet that transports a physical distribution container 1 that is not limited to the physical distribution container 1, and the IC tag 50 is attached to the outer surface of the pallet.
[0042] 図 11は、販売会社の物流センター 82における検品作動の一例を示している。物流 センター 82には、検品を行うためのリーダ一 ·ライター 51が物流センター 8の入口あ るいは屋根等に設置されている。このリーダー 'ライター 51は、モニター 52に接続さ れており、モニター 52が検品結果を可視表示する。物流用容器 1はパレット 54上に 整列された状態でトラック 53によって搬送される。搬送された物流用容器 1はパレット 54と共にトラック 53からリーダー ·ライター 51の下方に荷下ろしされる。  FIG. 11 shows an example of the inspection operation in the distribution center 82 of the sales company. In the distribution center 82, a reader / writer 51 for inspection is installed at the entrance of the distribution center 8 or on the roof. This reader / writer 51 is connected to a monitor 52, and the monitor 52 displays the inspection result visually. The logistics container 1 is transported by the truck 53 while being aligned on the pallet 54. The transported container 1 is unloaded from the truck 53 and below the leader / writer 51 together with the pallet 54.
[0043] パレット 54上に整列されて荷下ろしされた物流用容器 1は、リーダー 'ライター 51か ら離れた位置にあっても長距離通信可能な UHF帯 ICタグ 50が取り付けられている ため、リーダー 'ライター 51はその情報を確実に読み取ることができ、迅速に検品す ることができる。検品後の物流用容器 1は、リフター 55によって搬送され、検品及び納 入が終了する。このように UHF帯 ICタグ 50を用いることにより、整列状態での検品及 びリーダー 'ライター 51から離れた場所での検品が可能となる。従って、検品作業を 迅速に行うことができる。  [0043] Since the logistics container 1 aligned and unloaded on the pallet 54 is equipped with a UHF band IC tag 50 capable of long-distance communication even at a position away from the reader / writer 51, Reader 'Writer 51 can read the information reliably and inspect quickly. After inspection, the logistics container 1 is transported by the lifter 55, and inspection and delivery are completed. By using the UHF band IC tag 50 in this way, inspection in an aligned state and inspection away from the reader / writer 51 are possible. Therefore, inspection work can be performed quickly.
[0044] 図 3は本発明の第 2実施形態を示す。この実施形態にお!、ても、 ICタグ 2A及び IC タグ 3Aが物流用容器の外面やパレットの外面に貼り付けられることにより製品や部品 の検品に使用される。検品に際しては、物流用容器やパレットが横並び状の整列状 態となり、この整列によって一方の ICタグ 2A及び他方の ICタグ 3Aは表面が重ね合 わせられた状態となる。符号 Zは、 ICタグ 2A、 3 Aを線対称位置に配置した場合の線 対称軸であり、この線対称軸 Zに沿って折り曲げることにより、 ICタグ 2A, 3Aは上下 及び左右の方向が同じとなって表面が相互に重なり合い、物流用容器やパレットを 横並び状に整列させたときの重なり合い状態と同様となる。  FIG. 3 shows a second embodiment of the present invention. Even in this embodiment, the IC tag 2A and the IC tag 3A are attached to the outer surface of the physical distribution container or the outer surface of the pallet to be used for inspection of products and parts. At the time of inspection, logistics containers and pallets are in a side-by-side alignment state, and by this alignment, the surface of one IC tag 2A and the other IC tag 3A are superposed. Symbol Z is an axis of line symmetry when the IC tags 2A and 3A are arranged at line symmetry positions. By bending along the line symmetry axis Z, the IC tags 2A and 3A have the same vertical and horizontal directions. The surfaces overlap each other, which is similar to the overlapping state when logistics containers and pallets are aligned side by side.
[0045] 一方の ICタグ 2Aにおいて、そのアンテナ 22のパターンは ICチップ 23に対する上 下位置に形成されるものであり、 ICチップ 23の上下位置に対して複数段の櫛歯状パ ターンとなって配置されている。これに対し、他方の ICタグ 3Aにおけるアンテナ 32の パターンは、 ICチップ 33の上下に矩形状となって形成される。矩形状のアンテナ 32 は一方の ICタグ 2Aの櫛歯状アンテナ 22よりも幅広で上下方向に長くなつて 、る。こ のような 2つの ICタグ 2A及び 3Aの表面が重ね合わせられても、一方の ICタグ 2Aの アンテナ 22は他方の ICタグ 3Aのアンテナ 32に囲まれてアンテナ 32の内方に位置 する。又、このとき、アンテナ 22とアンテナ 32とは交差する部分も存在しない。このた め、アンテナ 22, 32が重なり合うことがない。従って、アンテナ 22, 32の送信や受信 に支障が生じることがなぐ安定した送受信を行うことができ、 ICタグ 2A, 3Aへのデ ータの書き込みやデータの読み取りを確実に行うことができる。 [0045] In one IC tag 2A, the pattern of the antenna 22 is higher than that of the IC chip 23. It is formed at the lower position, and is arranged in a plurality of comb-like patterns with respect to the upper and lower positions of the IC chip 23. On the other hand, the pattern of the antenna 32 in the other IC tag 3A is formed in a rectangular shape above and below the IC chip 33. The rectangular antenna 32 is wider and longer in the vertical direction than the comb-shaped antenna 22 of one IC tag 2A. Even if the surfaces of the two IC tags 2A and 3A are overlapped, the antenna 22 of one IC tag 2A is surrounded by the antenna 32 of the other IC tag 3A and is located inside the antenna 32. At this time, there is no portion where the antenna 22 and the antenna 32 intersect. For this reason, antennas 22 and 32 do not overlap. Therefore, stable transmission and reception can be performed without causing any trouble in transmission and reception of the antennas 22 and 32, and data can be reliably written to and read from the IC tags 2A and 3A.
[0046] 図 4は本発明の第 3実施形態を示し、 ICタグ 2B及び ICタグ 3Bが物流用容器の外 面やパレットの外面に貼り付けられる。そして、物流用容器やパレットが横並び状の 整列状態となることにより一方の ICタグ 2B及び他方の ICタグ 3Bは表面が重ね合わ せられた状態となる。符号 Zは、 ICタグ 2B、 3Bを線対称位置に配置した場合の線対 称軸であり、線対称軸 Zに沿って折り曲げることにより、 ICタグ 2B, 3Bは上下及び左 右の方向が同じとなった状態で表面が相互に重なり合う。従って、物流用容器やパレ ットを横並び状に整列させたときの重なり合い状態と同様となる。  FIG. 4 shows a third embodiment of the present invention, in which the IC tag 2B and the IC tag 3B are attached to the outer surface of the physical distribution container or the outer surface of the pallet. When the distribution containers and pallets are aligned side by side, the surfaces of one IC tag 2B and the other IC tag 3B are overlapped. Symbol Z is a line symmetrical axis when the IC tags 2B and 3B are arranged in a line-symmetric position. By bending along the line-symmetric axis Z, the IC tags 2B and 3B have the same vertical and left-right directions. In this state, the surfaces overlap each other. Therefore, it is the same as the overlapping state when logistics containers and pallets are aligned side by side.
[0047] この実施形態において、一方の ICタグ 2Bには、 ICチップ 23を中心にした上下位 置にクランク状パターンのアンテナ 22が形成されている。他方の ICタグ 3Bにも、実線 で示すように ICチップ 33を中心にした上下位置にクランク状パターンのアンテナ 32 が形成されている。これらのアンテナ 22及び 32は同一の長さで、且つ同じ長さ位置 で屈曲するように形成されるものであり、 ICタグ 2B側のアンテナ 22に対し、 ICタグ 3B 側のアンテナ 32は同じ方向に屈曲している。従って、アンテナ 22及び 32は線対称 軸 Zに対して非対称となっている。このような配置では、上下及び左右の方向を同じ にした状態で ICタグ 2B、 3Bの表面が重ね合わせられても、アンテナ 22, 32が相互 に重なり合うことがなぐ送信や受信に支障を生じることがない。  In this embodiment, one IC tag 2B is formed with an antenna 22 having a crank-like pattern at the upper and lower positions with the IC chip 23 as the center. On the other IC tag 3B, as shown by a solid line, an antenna 32 having a crank-like pattern is formed at the vertical position around the IC chip 33. These antennas 22 and 32 have the same length and are bent at the same length position. The antenna 32 on the IC tag 3B side is the same direction as the antenna 22 on the IC tag 2B side. Is bent. Therefore, the antennas 22 and 32 are asymmetric with respect to the line symmetry axis Z. In such an arrangement, even if the surfaces of the IC tags 2B and 3B are overlapped with the vertical and horizontal directions being the same, the antennas 22 and 32 will not interfere with each other, which may hinder transmission and reception. There is no.
[0048] 図 4において、鎖線 32dのパターンは ICタグ 3B側に形成されたアンテナであり、 IC タグ 2B側のアンテナ 22と線対称位置となるように形成されて!、る。このような線対称 位置のアンテナ 32dでは、 ICタグ 2B、 3Bを重ね合わせたとき、アンテナ 22, 32dの ほとんどが相互に重なり合った状態となる。このように重なり合うことにより電波の送信 や受信に支障となるため好ましくない。 In FIG. 4, the pattern of the chain line 32d is an antenna formed on the IC tag 3B side, and is formed so as to be symmetrical with the antenna 22 on the IC tag 2B side. Such line symmetry In the antenna 32d at the position, when the IC tags 2B and 3B are overlapped, most of the antennas 22 and 32d are overlapped with each other. This overlapping is not preferable because it interferes with the transmission and reception of radio waves.
[0049] 図 5は本発明の第 4実施形態を示す。 ICタグ 2C及び ICタグ 3Cが物流用容器の外 面やパレットの外面に貼り付けられる。そして、物流用容器やパレットが横並び状の 整列状態となることにより、一方の ICタグ 2C及び他方の ICタグ 3Cは表面が重ね合 わせられる。符号 Zは、 ICタグ 2C、 3Cを線対称位置に配置した場合の線対称軸であ り、線対称軸 Zに沿って折り曲げることにより、 ICタグ 2A, 3Aは上下及び左右方向が 同じとなった状態で表面が相互に重なり合う。従って、物流用容器やパレットを横並 び状に整列させたときの重なり合いと同様となる。  FIG. 5 shows a fourth embodiment of the present invention. IC tag 2C and IC tag 3C are affixed to the outer surface of the logistics container and the outer surface of the pallet. Then, when the distribution containers and pallets are aligned side by side, the surfaces of one IC tag 2C and the other IC tag 3C are overlapped. Symbol Z is an axis of line symmetry when the IC tags 2C and 3C are arranged in line symmetry positions. By bending along the line symmetry axis Z, the IC tags 2A and 3A have the same vertical and horizontal directions. The surfaces overlap each other in the wet state. Therefore, it is the same as the overlapping when logistics containers and pallets are aligned side by side.
[0050] この実施形態における一方の ICタグ 2Cには、ベースシート 21の左側上部に角型 渦巻き状パターンのアンテナ 22及びアンテナ 22に接続された ICチップ 23が設けら れている。また、他方の ICチップ 3Cには、右側下部に角型渦巻き状パターンのアン テナ 32及びアンテナ 32に接続された ICチップ 33が設けられている。このような配置 構造において、上下及び左右方向を同じにした状態で ICタグ 2C及び 2Dの表面を 重ね合わせても、線対称軸 Zに対して非対称であり、し力もアンテナ 22、 32が離れて いるため、相互に重なり合うことがない。従って、アンテナ 22、 32による電波の送信 や受信を円滑に行うことができ、確実な送受信が可能となる。  [0050] One IC tag 2C in this embodiment is provided with an antenna 22 having a square spiral pattern and an IC chip 23 connected to the antenna 22 on the upper left side of the base sheet 21. The other IC chip 3C is provided with an antenna 32 having a square spiral pattern and an IC chip 33 connected to the antenna 32 at the lower right side. In such an arrangement structure, even if the surfaces of the IC tags 2C and 2D are overlapped with the same vertical and horizontal directions, they are asymmetric with respect to the axis of line symmetry Z, and the antennas 22 and 32 are separated from each other. Therefore, they do not overlap each other. Therefore, radio waves can be transmitted and received smoothly by the antennas 22 and 32, and reliable transmission and reception is possible.
[0051] 図 6は本発明の第 5実施形態を示す。 ICタグ 2D及び ICタグ 3Dが物流用容器の外 面やパレットの外面に貼り付けられる。そして、物流用容器やパレットが横並び状の 整列状態となることにより、一方の ICタグ 2D及び他方の ICタグ 3Dの表面が重ね合 わせられる。符号 Zは、 ICタグ 2D、 3Dを線対称位置に配置した場合の線対称軸で あり、線対称軸 Zに沿って折り曲げることにより、 ICタグ 2D、 3Dは上下及び左右の方 向が同じとなった状態で表面が相互に重なり合う。従って、物流用容器やパレットを 横並び状に整列させたときの重なり合い状態と同様となる。  FIG. 6 shows a fifth embodiment of the present invention. IC tag 2D and IC tag 3D are affixed to the outer surface of the container for distribution and the outer surface of the pallet. The distribution containers and pallets are aligned side by side, so that the surfaces of one IC tag 2D and the other IC tag 3D are overlapped. Symbol Z is a line symmetry axis when the IC tags 2D and 3D are arranged in a line symmetry position. By bending along the line symmetry axis Z, the IC tags 2D and 3D have the same vertical and horizontal directions. In this state, the surfaces overlap each other. Therefore, it is the same as the overlapping state when logistics containers and pallets are aligned side by side.
[0052] 一方の ICタグ 2Dには、ベースシート 21の中央よりも左側に位置した部分に ICチッ プ 23が配置され、 ICチップ 23には角型渦巻き状パターンとなったアンテナ 22が連 結されている。他方の ICタグ 3Dも同様であり、ベースシート 21の中央よりも左側に位 置した部分に ICチップ 33が配置され、この ICチップ 33に角型渦巻き状パターンとな つたアンテナ 32が連結されている。アンテナ 22及び 32は略同じ大きさとなるように形 成されている。このように渦巻き状パターンのアンテナ 22、 32力ベースシート 21、 31 の同じ側に配置されることにより、上下及び左右の方向を同じにした状態で ICタグ 2 D、 3Dの表面を重ね合わせても、アンテナ 22、 32が相互に重なり合うことがない。こ のため、 ICタグ 2D、 3Dの送受信に支障となることがない。 [0052] On one IC tag 2D, an IC chip 23 is disposed at a portion located on the left side of the center of the base sheet 21, and an antenna 22 having a square spiral pattern is connected to the IC chip 23. Has been. The same applies to the other IC tag 3D, which is located on the left side of the center of the base sheet 21. An IC chip 33 is disposed on the placed portion, and an antenna 32 having a square spiral pattern is connected to the IC chip 33. The antennas 22 and 32 are formed to have substantially the same size. Thus, by arranging the spiral-shaped antennas 22 and 32 on the same side of the force base sheets 21 and 31, the surfaces of the IC tags 2D and 3D are superposed with the same vertical and horizontal directions. However, the antennas 22 and 32 do not overlap each other. For this reason, there is no hindrance to the transmission and reception of IC tags 2D and 3D.
[0053] 図 6において、鎖線で示すパターンアンテナ 32cを他方の ICチップに形成した場合 、このアンテナ 32cは ICタグ 2D側のアンテナ 22と線対称位置となる。このような線対 称位置のアンテナ 32cでは、 ICタグ 2B、 3Bを重ね合わせたとき、アンテナ 22, 32c のほとんどが相互に重なり合った状態となるため、電波の送信や受信の支障となって 好ましくない。 In FIG. 6, when the pattern antenna 32c indicated by a chain line is formed on the other IC chip, the antenna 32c is in a line-symmetrical position with the antenna 22 on the IC tag 2D side. In the antenna 32c in such a line-symmetric position, when the IC tags 2B and 3B are overlapped, most of the antennas 22 and 32c are overlapped with each other. Absent.
[0054] 図 7は本発明の第 6実施形態を示す。 ICタグ 2E及び ICタグ 3Eが物流用容器の外 面やパレットの外面に貼り付けられ、物流用容器やパレットが横並び状の整列状態と なることにより一方の ICタグ 2E及び他方の ICタグ 3Eの表面が重ね合わせられる。図 7において、符号 Zは、 ICタグ 2E、 3Eを線対称位置に配置した場合の線対称軸であ り、線対称軸 Zに沿って折り曲げることにより ICタグ 2E、 3Eの表面が相互に重なり合 うため、物流用容器やパレットを横並び状に整列させたときの重なり合い状態と同様 となる。  FIG. 7 shows a sixth embodiment of the present invention. The IC tag 2E and the IC tag 3E are attached to the outer surface of the distribution container and the outer surface of the pallet, and the distribution container and pallet are aligned side by side so that one of the IC tag 2E and the other IC tag 3E The surfaces are superimposed. In FIG. 7, reference symbol Z denotes a line symmetry axis when the IC tags 2E and 3E are arranged at line symmetry positions, and the surfaces of the IC tags 2E and 3E overlap each other by being bent along the line symmetry axis Z. Therefore, it is the same as the overlapping state when logistics containers and pallets are aligned side by side.
[0055] ICタグ 2E及び 3Eは、ベースシート 21, 31上に ICチップ 23、 33及びアンテナ 22、 32が設けられることにより構成されている。一方の ICタグ 2Eにおいては、 ICチップ 2 3の上下位置にアンテナ 22が形成されている。それぞれのアンテナ 22は ICチップ 2 3に近接した位置に設けられている。これらのアンテナ 22は、 ICチップ 23に近接した 上下位置で、左右の横方向に伸びると共に左右の横方向への屈曲を複数繰り返し た複数段の櫛歯状パターンとなって 、る。  The IC tags 2E and 3E are configured by providing IC chips 23 and 33 and antennas 22 and 32 on base sheets 21 and 31, respectively. On the other hand, in the IC tag 2E, the antenna 22 is formed at the upper and lower positions of the IC chip 23. Each antenna 22 is provided at a position close to the IC chip 23. These antennas 22 have a plurality of comb-like patterns extending in the left and right lateral directions and repeatedly bent in the left and right lateral directions at a vertical position close to the IC chip 23.
[0056] 他方の ICタグ 3Eにおいては、 ICチップ 33の左右位置にアンテナ 32が形成されて いる。 ICタグ 3Eのそれぞれのアンテナ 32は、 ICチップ 33から左右の方向に直線状 に伸びる脚状パターン部 32mと、脚状パターン部 32mの先端部分で上下方向に伸 びると共に上下方向への屈曲を複数繰り返した複数段の櫛歯状パターン部 32ηとを 備えている。脚状パターン部 32mは、一方の ICタグ 2Eのアンテナ 22の横方向長さ よりも長くなるように設定される。このようなパターンとなっていることにより、アンテナ 3 2は線対称軸 Zに対し、アンテナ 22と非対称となっているのにカ卩えて、アンテナ 32は I Cタグ 2Eのアンテナ 22の形成領域の外側に位置する。 In the other IC tag 3E, antennas 32 are formed on the left and right positions of the IC chip 33. Each antenna 32 of the IC tag 3E has a leg-shaped pattern portion 32m that extends linearly from the IC chip 33 in the left-right direction, and extends vertically at the tip of the leg-shaped pattern portion 32m and bends in the vertical direction. A plurality of repeated comb-like pattern portions 32η I have. The leg-shaped pattern portion 32m is set to be longer than the lateral length of the antenna 22 of one IC tag 2E. Because of this pattern, the antenna 32 is asymmetric with the antenna 22 with respect to the line symmetry axis Z, and the antenna 32 is located outside the area where the antenna 22 of the IC tag 2E is formed. Located in.
[0057] 図 7に示すアンテナの配置状態で、上下及び左右の方向を同じにして ICタグ 2E、 3Eを重ね合わせると、アンテナ 22とアンテナ 32とが相互に重なり合うことがない。従 つて、アンテナ 22、 32による電波の送信や受信を円滑に行うことができ、確実な送受 信が可能となる。 When the IC tags 2E and 3E are overlapped with the same vertical and horizontal directions in the antenna arrangement state shown in FIG. 7, the antenna 22 and the antenna 32 do not overlap each other. Therefore, radio waves can be transmitted and received smoothly by the antennas 22 and 32, and reliable transmission and reception is possible.
[0058] 図 8は、本発明の第 7実施形態を示す。 ICタグ 2F及び 3Fが物流用容器の外面や ノルットの外面に貼り付けられ、物流用容器やパレットが横並び状の整列状態となる ことにより一方の ICタグ 2E及び他方の ICタグ 3Eの表面が重ね合わせられる。図 8に おいて、符号 Zは ICタグ 2E、 3Eを線対称位置に配置した場合の線対称軸であり、線 対称軸 Zに沿って折り曲げることにより ICタグ 2F、 3Fの表面が相互に重なり合う。こ れにより、物流用容器やパレットを横並び状に整列させたときの重なり合い状態と同 様となる。  FIG. 8 shows a seventh embodiment of the present invention. IC tags 2F and 3F are affixed to the outer surface of the logistics container and the outer surface of the knot, and the surface of the one IC tag 2E and the other IC tag 3E are overlapped by aligning the logistics container and pallet side by side. Adapted. In FIG. 8, the symbol Z is a line symmetry axis when the IC tags 2E and 3E are arranged at line symmetry positions, and the surfaces of the IC tags 2F and 3F overlap each other by being bent along the line symmetry axis Z. . This is similar to the overlapping state when logistics containers and pallets are aligned side by side.
[0059] 一方の ICタグ 2Fにおいては、 ICチップ 23の上下位置にアンテナ 22が配置されて V、る。それぞれのアンテナ 22は ICチップ 23から上下の方向に伸びる脚状パターン 部 22mと、脚状パターン部 22mの先端部分で左右方向に伸びると共に左右方向へ の屈曲を複数繰り返した複数段の横櫛歯状パターン部 22ηとを備えている。この場 合、脚状パターン部 22mは、横櫛歯状パターン部 22ηが ICチップ 23から十分に離 れるように長くなつている。  [0059] In one IC tag 2F, an antenna 22 is arranged at the upper and lower positions of the IC chip 23, and V. Each antenna 22 includes a leg-shaped pattern portion 22m extending in the vertical direction from the IC chip 23, and a plurality of horizontal comb teeth extending in the left-right direction at the tip of the leg-shaped pattern portion 22m and repeatedly bending in the left-right direction. Pattern portion 22η. In this case, the leg-shaped pattern portion 22m is long so that the horizontal comb-shaped pattern portion 22η is sufficiently separated from the IC chip 23.
[0060] 他方の ICタグ 3Fは、図 7における ICタグ 3Εと同様となっている。すなわち、 ICタグ 3Εにおいては、 ICチップ 33の左右位置にアンテナ 32が形成され、それぞれのアン テナ 32は、 ICチップ 33から左右の方向に直線状に伸びる脚状パターン部 32m及び 脚状パターン部 32mの先端部分で上下方向に伸びると共に上下方向への屈曲を複 数繰り返した複数段の縦櫛歯状パターン部 32ηによって構成されて 、る。 ICタグ 3F においても、脚状パターン部 32mは、縦櫛歯状パターン部 32ηが ICチップ 33から十 分に離れるように長くなつて形成されるものである。 [0061] このようなパターンとなっていることにより、アンテナ 22及びアンテナ 32は線対称軸 Zに対して非対称となっている。これに加えて、それぞれの ICタグ 2F、 3Fでは、脚状 パターン部 22m、 32mが長くなつているため、横櫛歯状パターン部 22m、縦櫛歯状 パターン部 32mがベースシート 21, 31の外縁に接近した位置となっている。このよう な ICタグ 2F、 3Fを、上下及び左右の方向を同じにして重ね合わせると、アンテナ 22 とアンテナ 32とが相互に重なり合うことがない。従って、アンテナ 22、 32による電波の 送信や受信を円滑に行うことができ、確実な送受信が可能となる。 [0060] The other IC tag 3F is the same as the IC tag 3F in FIG. That is, in the IC tag 3Ε, the antenna 32 is formed at the left and right positions of the IC chip 33, and each antenna 32 has a leg-shaped pattern portion 32m and a leg-shaped pattern portion extending linearly from the IC chip 33 in the left-right direction. It is composed of a plurality of vertical comb-like pattern portions 32η that extend in the vertical direction at the tip portion of 32 m and are repeatedly bent in the vertical direction. Also in the IC tag 3F, the leg-shaped pattern portion 32m is formed to be long so that the vertical comb-shaped pattern portion 32η is sufficiently separated from the IC chip 33. Due to this pattern, the antenna 22 and the antenna 32 are asymmetric with respect to the line symmetry axis Z. In addition, in each IC tag 2F and 3F, the leg-shaped pattern portions 22m and 32m are long, so the horizontal comb-shaped pattern portion 22m and the vertical comb-shaped pattern portion 32m The position is close to the outer edge. When such IC tags 2F and 3F are overlapped with the same vertical and horizontal directions, the antenna 22 and the antenna 32 do not overlap each other. Therefore, radio waves can be transmitted and received smoothly by the antennas 22 and 32, and reliable transmission and reception is possible.
[0062] 図 9は本発明の第 8実施形態を示す。この実施形態における一方の ICタグ 22Eは 、ベースシート 21の中央の ICチップ 23と、 ICチップ 23に接続された 2つのアンテナ 2 2を有している。 2つのアンテナ 22は、矩形状となっていると共に ICチップ 23を挟ん だパターンに形成されて 、る。  FIG. 9 shows an eighth embodiment of the present invention. One IC tag 22E in this embodiment has an IC chip 23 in the center of the base sheet 21 and two antennas 22 connected to the IC chip 23. The two antennas 22 have a rectangular shape and are formed in a pattern sandwiching the IC chip 23.
[0063] 他方の ICタグ 3Eは、ベースシート 31の中央の ICチップ 33に 2つのアンテナ 32が 接続された構造となって 、る。 2つのアンテナ 32は ICチップ 33を左右力も挟むパタ ーンとなって ICチップ 33の両側に設けられている。また、 2つのアンテナ 32は上下方 向に大きく延びると共に、左右方向にも大きく延びており、これにより一方の ICタグ 2 Eのアンテナ 22を十分に包み込むことが可能な大きさとなっている。  [0063] The other IC tag 3E has a structure in which two antennas 32 are connected to an IC chip 33 in the center of the base sheet 31. The two antennas 32 are provided on both sides of the IC chip 33 in a pattern that sandwiches the IC chip 33 between the left and right forces. In addition, the two antennas 32 greatly extend upward and downward, and also extend in the left-right direction, so that the antenna 22 of one IC tag 2E can be sufficiently wrapped.
[0064] このような ICタグ 2E及び ICタグ 3Eの上下及び左右方向を同じにした状態で 2つの ICタグ 2E、 3Eの表面を重ね合わせた場合、 ICタグ 2E側のアンテナ 22は、 ICタグ 3 E側のアンテナ 32に囲まれた状態となる。このとき、アンテナ 22及び 32は相互に交 差する部分が発生するが、その他の大部分は相互に重なり合うことがない。このよう にアンテナ 22, 32の一部が重なり合っていても、大部分は重なっていない。このため 、アンテナ 22及び 32は電波の送信及び受信を確実に行うことができる。従って、電 波の送信や受信の支障となることがなぐ ICチップ 23, 33へのデータの読み取りや 書き込みを行うことができる。  [0064] When the surfaces of the two IC tags 2E and 3E are overlapped with the IC tag 2E and the IC tag 3E being in the same vertical and horizontal directions, the antenna 22 on the IC tag 2E side is 3 Surrounded by the antenna 32 on the E side. At this time, the antennas 22 and 32 are crossed with each other, but most other parts do not overlap each other. Thus, even if some of the antennas 22 and 32 overlap, most do not overlap. Therefore, the antennas 22 and 32 can reliably transmit and receive radio waves. Therefore, it is possible to read and write data to the IC chips 23 and 33 that do not hinder the transmission and reception of the electric wave.
[0065] 以上のようなアンテナ 22, 32の部分的な重なりは、重なっていない部分に対して極 力少ないことが好ましぐアンテナ 22, 32の全長(又は全面積)を Xとした場合、 0. 0 1X(1%)〜0. 2X(20%)が良好であり、 0. 01X(1%)〜0. 10X(10%)の範囲がさ らに良好である。 [0066] 本発明は、以上の実施形態に限定されることなぐ種々変形が可能である。例えば 、 2つの ICタグのアンテナは相互に重なり合わなければ、図示した実施形態以外の パターンとすることが可能である。 [0065] The partial overlap of the antennas 22 and 32 as described above is preferable when X is the total length (or total area) of the antennas 22 and 32 where it is preferable that the antennas 22 and 32 be as small as possible with respect to the non-overlapping parts. The range of 0.01X (1%) to 0.2X (20%) is good, and the range of 0.01X (1%) to 0.10X (10%) is even better. The present invention can be variously modified without being limited to the above embodiments. For example, if the antennas of the two IC tags do not overlap with each other, a pattern other than the illustrated embodiment can be used.
