Description

本発明は、通信距離が短い従来のＲＦＩＤが内蔵された情報記録担体の不具合を克服し、平面（垂直方向）からではなく、側面（水平方向）からの通信距離を伸ばすことが可能な情報記録担体に関する。
The present invention overcomes the disadvantages of conventional information record carriers with a short communication distance built-in RFID, and can extend the communication distance from the side surface (horizontal direction) instead of from the flat surface (vertical direction). Relates to the carrier.

従来、内蔵されたＲＦＩＤ（Ｒａｄｉｏ Ｆｒｅｑｕｅｎｃｙ−Ｉｄｅｎｔｉｆｉｃａｔｉｏｎ）の通信距離を伸ばすよう工夫したＲＦＩＤタグ（情報記録担体）が知られている（例えば、特許文献１参照）。
特許文献１のＲＦＩＤタグによれば、誘電体などからなる第１部品と、この第１部品に電気的に接続される通信アンテナおよび回路チップなどを備えた第２部品とを張り合わせることにより読取り・書込み装置などによる読取り・書込みの通信距離を長くしている。
しかしながら、前記のＲＦＩＤタグは、アンテナに対して正面（垂直方向）からの読取り・書込みに対する通信距離は長くなるものの、側面（水平方向）からの読取り・書込みはほとんどできないという問題があった。
上記の問題点である側面側（水平方向）からの読取り・書込みに対応し、アンテナとの相対角度、あるいは、物品に貼付される場合にはその貼付面によらずに情報書込み／読込み装置との通信距離を一定にしたＲＦ−ＩＤメディア（情報記録担体）が開発されている（例えば、特許文献２参照）。
特許文献２のＲＦ−ＩＤメディアによれば、ベース基材を折り曲げ可能な折り線を介して複数の領域に分割し、被対象物の縁に前記折り線を合わせ１つの領域を側面に折り曲げ、それぞれの領域にて、ＩＣモジュールに対する情報の書き込みおよび読み出しを行うためのアンテナを形成することにより、領域が形成された複数の面に対する書込み・読出しの通信距離を一定としたものである。
しかしながら、特許文献２のＲＦ−ＩＤメディアは、アンテナが形成された領域が大きいため、これを貼り付ける被対象物が大きい場合には折り曲げは可能であるものの、例えば、書架に並んだ書籍やラックに陳列するＣＤなどに張り付けた場合、折り曲げた領域により書名や収納音楽などのタイトルが表示された背表紙が隠されてしまうため、厚みの薄い書籍やＣＤには不向きであるという問題があり、書籍やＣＤなどの厚みの薄い物に用いることができ、しかも、書架やラックなどに並べられた場合でも背表紙の方向から読み取れるようなＲＦ−ＩＤメディア（情報記録担体）の開発が望まれた。
特開２００６−３０１６９０号公報 特開２００３−２１６９１９号公報 Conventionally, an RFID tag (information record carrier) devised to extend the communication distance of a built-in RFID (Radio Frequency-Identification) is known (see, for example, Patent Document 1).
According to the RFID tag of Patent Document 1, reading is performed by bonding together a first component made of a dielectric or the like and a second component including a communication antenna and a circuit chip that are electrically connected to the first component.・ The reading / writing communication distance by the writing device is increased.
However, the RFID tag has a problem in that reading / writing from the side surface (horizontal direction) is hardly possible although the communication distance for reading / writing from the front surface (vertical direction) is long with respect to the antenna.
Corresponding to reading and writing from the side (horizontal direction), which is the above problem, the information writing / reading device and the relative angle with the antenna, or when attached to an article, regardless of the attached surface RF-ID media (information record carrier) with a constant communication distance have been developed (see, for example, Patent Document 2).
According to the RF-ID media of Patent Document 2, the base substrate is divided into a plurality of regions via a foldable fold line, the fold line is aligned with the edge of the object, and one region is bent to the side surface. By forming an antenna for writing and reading information to and from the IC module in each area, the communication distance for writing and reading to a plurality of surfaces on which the area is formed is made constant.
However, since the RF-ID media of Patent Document 2 has a large area where an antenna is formed, it can be folded when the object to be attached is large, but for example, books or racks lined up on a bookshelf When pasted on a CD or the like to be displayed, the back cover on which titles such as titles and stored music are displayed is hidden by the folded area, which is not suitable for thin books and CDs. Development of RF-ID media (information record carrier) that can be used for thin objects such as books and CDs and that can be read from the direction of the back cover even when arranged on a bookshelf or rack is desired. .

本発明は、上記の問題点に着目してなされたものであり、被貼付物に貼り付けた際、アンテナが配された正面（平面）に対し、側面よりの書込み・読取りが可能な情報記録担体を提供することを目的とする。
The present invention has been made paying attention to the above-mentioned problems, and can be written and read from the side with respect to the front surface (planar surface) on which the antenna is arranged when pasted on an object. The object is to provide a carrier.

本発明に係る情報記録担体は、矩形状の基材と、前記基材に貼り合わせるとともに、矩形状の一辺より対向する他辺に向けて導波用アンテナ、情報の書込みおよび読込みを可能としたＩＣチップを備えた受信用アンテナ、反射用アンテナが平面上に順次配されたＲＦＩＤインレットと、を備えたことを特徴とする。
また、各アンテナ間の距離は等間隔であるようにできる。
また、導波用アンテナ、受信用アンテナおよび反射用アンテナの各アンテナ間を結ぶ接続部材を、さらに設けるようにできる。
The information recording carrier according to the present invention is bonded to a rectangular base material and the base material, and also enables a waveguide antenna to write and read information from one side of the rectangular shape toward the opposite side. A reception antenna including an IC chip and an RFID inlet in which reflection antennas are sequentially arranged on a plane are provided.
Moreover, the distance between each antenna can be made equal intervals.
Further, it is possible to further provide a connecting member for connecting the antennas for waveguide, reception, and reflection.

発明に係る情報記録担体は、矩形状の一辺より対向する他辺に向けて導波用アンテナ、情報の書込みおよび読込みを可能としたＩＣチップを備えた受信用アンテナ、および反射用アンテナを順次配したＲＦＩＤインレットを基材に貼りあわせて積層したので、側面である一辺側からの電波に対し、先ず導波用アンテナにおいて受けた電波が共振して受信アンテナに伝わるとともに、導波用アンテナにて受信できなかった電波はＩＣチップに接続された次の受信用アンテナで受信でき、さらに、導波用アンテナおよび受信用アンテナで受信できずに通り過ぎた電波は最奥部に配される反射用アンテナで受信され、共振した電波を受信用アンテナに伝えることにより電波が有効に作用するため、もって一辺（側面）側からの読取り・書込みの通信距離が伸びるという効果がある。
また、各アンテナ間の距離を位相の強め合う等間隔の距離とすれば、共振がより強力となる。
また、導波用アンテナ、受信用アンテナおよび反射用アンテナの各アンテナ間を結ぶ接続部材を、さらに設けるようにすれば、共振の伝達がより確実となる。
An information recording carrier according to the invention sequentially arranges a waveguide antenna, a receiving antenna having an IC chip that enables writing and reading of information, and a reflecting antenna from one side of a rectangular shape to the other side opposite to each other. Since the RFID inlet was laminated to the base material, the radio wave received at the waveguide antenna first resonated with the radio wave from one side of the side and transmitted to the receiving antenna. The radio waves that could not be received can be received by the next receiving antenna connected to the IC chip, and the radio waves that have passed without being received by the waveguide antenna and the receiving antenna are distributed in the innermost part. Because the radio wave works effectively by transmitting the resonated radio wave received at the receiving antenna to the receiving antenna, reading / writing communication from one side (side) side There is an effect that away is extended.
In addition, if the distance between the antennas is an equally spaced distance that reinforces the phase, the resonance becomes stronger.
Further, if a connecting member for connecting the waveguide antenna, the receiving antenna, and the reflecting antenna is further provided, the transmission of resonance becomes more reliable.

上記の構成の情報記録担体１は、図示省略の印字装置により、前記厚紙６の表面側に必要項目情報を印字した上で、識別マーク７、７間の１ピッチＰごとに切断し、積層された基材４、ＲＦＩＤインレット５および厚紙６ごと台紙２より剥がして基材４裏面の粘着剤層３を表出し、この粘着剤層３を介して「被貼付物」に貼り付けが可能となっている。 Identification marks 7 are printed in advance on the back surface (lower part in FIG. 2) of the mount 2 at equal intervals. The space between the identification marks 7 and 7 is referred to as a pitch P and is a unit for printing and cutting. ing.
The base material 4 has a pressure-sensitive adhesive layer 3 formed on the back surface (lower part in FIG. 2), and is laminated to the mount 2 via the pressure-sensitive adhesive layer 3 as described above and is temporarily attached to be peelable. .

次に、主に、図３に基づき、情報記録担体１の使用状態につき説明する。
図３は、棚（ＣＤラック）２０に並べられた被貼付物としてのＣＤ２１に情報記録担体１を貼り付けた状態を示す概略斜視図である。
情報記録担体１をＣＤ２１に表示する際、導波用アンテナ１２が配された一辺８ａ側を背表紙側に、また、反射用アンテナ１４が配された他辺８ｂ側を棚２０の奥側になるようＣＤ２１の側面に貼り付ける。
棚２０に並べられたＣＤ２１の側面に貼り付けられた情報記録担体１は、図示省略の読取り・書込み装置にて読取り・書込みをする際、同記録担体１の平面（正面）であるＣＤ２１の側面（アンテナ９が配された平面に対し垂直方向である矢示Ｓ方向）からは棚２０や他のＣＤ２１が邪魔となって読み取れない。必然的にＣＤ２１の背表紙側（アンテナ９が配された平面に対し水平方向である矢示Ａ方向）より読み取ることになる。このとき、情報記録担体１は、背表紙側に導波用アンテナ１２、その奥に受信用アンテナ１３、さらに奥に反射用アンテナ１４が、等間隔の距離ｄで配され、あたかも八木アンテナ（商標登録）のような配置状態を呈し、図示省略のＲＦＩＤ読取り装置よりの電波を背表紙側（矢示Ａ方向）より受けると導波用アンテナ１２において受けた電波が共振して受信アンテナ１３に伝わるとともに、導波用アンテナ１２にて受信できなかった電波はＩＣチップに接続された次の受信用アンテナ１３で受信でき、さらに、前記導波用アンテナ１２および受信用アンテナ１３で受信できずに通り過ぎた電波は最奥部に配される反射用アンテナ１４にて受信され、共振した電波を受信用アンテナ１３に伝え、電波が有効に作用するため、情報記録担体１の一辺８ａである側面（矢示Ａ方向）側からの読取り・書込みの通信距離が伸びるものである。従って、ＣＤ２１や書籍のように厚みの薄い被貼付物に貼り付けた場合、背表紙側よりの情報の読取り・書込みが可能となるため、棚２０に並べたＣＤ２１のように狭い場所における被貼付物の読取り・書込みに有効である。 Next, the use state of the information record carrier 1 will be described mainly with reference to FIG.
FIG. 3 is a schematic perspective view showing a state in which the information recording carrier 1 is attached to a CD 21 as an object to be attached arranged on a shelf (CD rack) 20.
When displaying the information record carrier 1 on the CD 21, the side 8 a side where the waveguide antenna 12 is arranged is on the back cover side, and the other side 8 b side where the reflecting antenna 14 is arranged is on the back side of the shelf 20. Affix to the side of CD21.
When the information record carrier 1 affixed to the side surface of the CD 21 arranged on the shelf 20 is read / written by a reading / writing device (not shown), the side surface of the CD 21 which is the plane (front surface) of the record carrier 1. The shelf 20 and the other CD 21 cannot be read from (in the direction indicated by the arrow S, which is the direction perpendicular to the plane on which the antenna 9 is disposed) because of the obstruction. Inevitably, reading is performed from the spine side of the CD 21 (in the direction of arrow A, which is horizontal with respect to the plane on which the antenna 9 is disposed). At this time, the information recording carrier 1 has a waveguide antenna 12 on the back cover side, a receiving antenna 13 on the back, and a reflecting antenna 14 on the back with an equal distance d, as if it were a Yagi antenna (trademark) When a radio wave from an RFID reader (not shown) is received from the spine side (arrow A direction), the radio wave received by the waveguide antenna 12 resonates and is transmitted to the reception antenna 13. At the same time, the radio wave that could not be received by the waveguide antenna 12 can be received by the next receiving antenna 13 connected to the IC chip, and further, the radio wave cannot be received by the waveguide antenna 12 and the receiving antenna 13. The received radio wave is received by the reflecting antenna 14 disposed at the innermost part, and the resonated radio wave is transmitted to the receiving antenna 13 so that the radio wave effectively acts. Communication distance of the read and write from an edge 8a side (arrow A direction) side in which extends. Therefore, when pasted on a thin object such as a CD 21 or a book, information can be read and written from the back cover side, so that the object is adhered in a narrow place like the CD 21 arranged on the shelf 20. Effective for reading and writing objects.

次に、図４に基づき、第２の実施の形態につき説明する。
なお、以下において、先の実施の形態と同様の部分は同一符号を付すに止め、詳細を省略する。
先の実施の形態では環状の、いわゆる低周波帯に用いるアンテナ９を例としたが、本実施の形態では、ＵＨＦ帯に対応した短い直線状のアンテナを用いた情報記録担体２４の例で説明する。
この情報記録担体２４のＲＦＩＤインレット２５は、シート基材８の一辺８ａより他辺８ｂに向けて複数の直線状のアンテナ２６が配されており、このアンテナ２６は、一辺８ａ側に長さが一番短い導波用アンテナ２７を配し、真ん中にＩＣチップ１０が接続された受信用アンテナ２８、そして、他辺８ｂ側に一番長い反射用アンテナ２９を配する。なお、導波用アンテナ２７と受信用アンテナ２８の間、および受信用アンテナ２８と反射用アンテナ２９の間は、おのおの等間隔の距離ｄとされている。
前記ＲＦＩＤインレット２５は、基材４に対し粘着剤（図示省略）を介して貼り合わせ、かつ、ＲＦＩＤインレット２５の上に厚紙６を積層して基材４と厚紙６とで挟んで形成するものであり、識別マーク７の位置に、ミシン目３０が施されている。従って、厚紙６の表面に必要項目情報を印字した後、積層された基材４、ＲＦＩＤインレット２５および厚紙６ごとミシン目３０に添って台紙２より剥がし基材４裏面の粘着剤層３を表出し、この粘着剤層３を介して「被貼付物」に貼り付けるようにする。
上記の情報記録担体２４をＣＤ２１に表示する際、導波用アンテナ２７が配された一辺８ａ側を背表紙側に、次に、受信用アンテナ２８、そして、反射用アンテナ２９が配された他辺８ｂ側を棚２０の奥側になるようＣＤ２１の側面に貼り付ける。
棚２０に並べられたＣＤ２１の側面に貼り付けられた情報記録担体２４は、背表紙側より導波用アンテナ２７、受信用アンテナ２８、および反射用アンテナ２９の順に配列された状態でＣＤ２１に貼り付けられて棚２０に陳列され、背表紙側よりの読取り・書込み装置（図示省略）による読取り・書込みに際し、受信用アンテナ２８で受信できなかった電波が導波用アンテナ２７、および反射アンテナ２９の共振により受信用アンテナ２８に伝わり、電波が有効に作用するので、一辺８ａである側面（矢示Ａ方向）側からの読取り・書込みの通信距離が伸びるものである。
その他の構成、作用、効果については、先の実施の形態とほぼ同様につき詳説を省略する。 Next, a second embodiment will be described with reference to FIG.
In the following, the same parts as those in the previous embodiment are given the same reference numerals, and the details are omitted.
In the previous embodiment, the annular antenna 9 used for the so-called low frequency band is taken as an example. In the present embodiment, the information recording carrier 24 using a short linear antenna corresponding to the UHF band is described as an example. To do.
The RFID inlet 25 of the information record carrier 24 is provided with a plurality of linear antennas 26 from the one side 8a to the other side 8b of the sheet base material 8, and this antenna 26 has a length on the side 8a side. The shortest waveguide antenna 27 is arranged, the receiving antenna 28 to which the IC chip 10 is connected in the middle, and the longest reflecting antenna 29 on the other side 8b side. It should be noted that the distance d between the waveguide antenna 27 and the reception antenna 28 and the distance between the reception antenna 28 and the reflection antenna 29 are equal distances d.
The RFID inlet 25 is formed by adhering to the base material 4 via an adhesive (not shown) and laminating the cardboard 6 on the RFID inlet 25 and sandwiching it between the base material 4 and the cardboard 6. A perforation 30 is provided at the position of the identification mark 7. Therefore, after the necessary item information is printed on the surface of the thick paper 6, the laminated base material 4, the RFID inlet 25 and the thick paper 6 are peeled off along the perforation 30 from the backing paper 2, and the adhesive layer 3 on the back surface of the base material 4 is displayed. It is taken out and pasted on the “object to be pasted” through the adhesive layer 3.
When the information record carrier 24 is displayed on the CD 21, the side 8 a side where the waveguide antenna 27 is arranged is on the back cover side, and then the receiving antenna 28 and the reflecting antenna 29 are arranged. The side 8b side is pasted on the side surface of the CD 21 so as to be the back side of the shelf 20.
The information record carrier 24 attached to the side surface of the CD 21 arranged on the shelf 20 is attached to the CD 21 in a state in which the waveguide antenna 27, the receiving antenna 28, and the reflecting antenna 29 are arranged in this order from the back cover side. At the time of reading / writing by the reading / writing device (not shown) from the back cover side, the radio waves that could not be received by the receiving antenna 28 are transmitted to the waveguide antenna 27 and the reflective antenna 29. Resonance is transmitted to the receiving antenna 28 and the radio wave acts effectively, so that the reading / writing communication distance from the side surface (in the direction of arrow A) that is the side 8a is increased.
About another structure, an effect | action, and an effect, detailed description is abbreviate | omitted since it is the same as that of previous embodiment.

その他の構成、作用、効果については、先の実施の形態とほぼ同様につき詳説を省略する。 Next, a third embodiment will be described with reference to FIG.
In the following, the same parts as those in the previous embodiment are given the same reference numerals, and the details are omitted.
The information record carrier 31 of this embodiment is characterized in that a “connection member” is provided in the information record carrier 24 of the previous embodiment. That is, the RFID inlet 32 of the information record carrier 31 has a waveguide antenna 27, a receiving antenna 28, and a reflecting antenna 29 arranged in order on the other side 8b side from the one side 8a to the other side 8b of the sheet substrate 8. In addition, the antennas 27, 28, and 29 are connected by connecting members 33. The connecting member 33 serves as a “dipole” provided so as to connect the waveguide antenna 27, the receiving antenna 28, and the reflecting antenna 29 so that resonance between the antennas 27, 28, and 29 can be easily transmitted. Has come to fulfill. Accordingly, the information recording carrier 31 configured as described above is peeled off from the mount 2 along the perforation 30 together with the laminated base material 4, RFID inlet 32, and cardboard 6, and the adhesive layer 3 on the back surface of the base material 4 is displayed. If it is attached to the “target object” via the adhesive layer 3, the radio wave that could not be received by the receiving antenna 28 at the time of reading / writing by the reading / writing device (not shown) from the back cover side Resonance occurs in the waveguide antenna 27 and the reflection antenna 29, and this resonance is also transmitted to the receiving antenna 28 through the connection member 33, so that the resonance efficiency is increased.
About another structure, an effect | action, and an effect, detailed description is abbreviate | omitted since it is the same as that of previous embodiment.

なお、上記実施の形態の構成及び動作は例であって、本発明の趣旨を逸脱しない範囲で適宜変更することができることは言うまでもない。   It should be noted that the configuration and operation of the above-described embodiment are examples, and it goes without saying that they can be changed as appropriate without departing from the spirit of the present invention.

例えば、説明の都合上、情報記録担体１、２４、３１は台紙２を備えた「ラベル」として説明したがこれに限定されないことは勿論であり、アンテナ９、２６およびＩＣチップ１０に干渉しない部分に図示省略の糸などを通して「ＲＦＩＤタグ」として使用することもできる。
For example, for the convenience of explanation, the information record carriers 1, 24, 31 have been described as “labels” provided with the mount 2, but of course not limited to this, portions that do not interfere with the antennas 9, 26 and the IC chip 10. It can also be used as an “RFID tag” through a thread (not shown).
