【0002】この発明はさらに、末梢の血流量の改善、筋肉の凝りの加温治療による寛解、癒しなど、生理学的な面で種々の改善効果を期待される電気石はじめ、各種アニオン発生物質、遠赤外線発生物質、磁性物質などの粉末状または粒状の機能性添加材を、該樹脂状ないしゴム状被覆・補強材料中に混合し、分散せしめて使用することによって、各種の生理学的パラメーターの改善効果を併せ発揮することが期待できるものである。
【0003】
【従来の技術】
長さが比較的短いサイズのアンテナを搭載したIDを、カード状などにして実用化しているものがあるが、このような短小なアンテナを搭載したRFIDはリーダー装置に対して接触させるか、非接触であっても数十mm以下の、至近距離まで近接させないと、必要な情報の授受を行うことができない不便さがあったもので、この状況はバーコードを用いた、腕時計タイプのID装置とほとんど同レベルの、便利さに欠けるものであった。
【0004】
【発明が解決しようとする課題】この発明の目的は従来のバーコードや、これと大差のなかった従来のICカードなどの、情報のやり取りの際のリーダーとの距離を、ほとんどとることが出来なかったことによる不便、たとえば交通機関における自動開札機に対して、ICカードを毎回懐中や鞄から取り出して、リーダー部に接触または近接させなければならない不便があったため、本発明者らはこれらの点を解消すべく鋭意検討した。
【0005】
【課題を解決するための手段】従来のICカードに比較すると、ループ状にするとともに、より大きなループ径のアンテナを作成し、さらにこれらアンテナに少なくとも柔軟性材料を使用して屈曲性を賦与するとともに、より望ましくは伸縮性を付与するものであり、そのための手段としては、搭載するアンテナを螺旋状、またはサイン・カーブ、3角波、矩形波などの波形に賦型することによって柔軟化し、屈曲性と、さらには伸縮性を付与するとともに、被覆・補強用の樹脂状ないしゴム状材料には、ゴム状弾性を持たせて柔軟化して屈曲性を賦与し、さらには伸縮性を賦与することにより着脱を容易にするとともに、装着中には該アンテナが余りにも長くなることにより受ける不便さや、不快感から開放することを可能にするものである。
【0006】さらにこの発明の被覆・補強用材料組成物中には粉砕した粉末状または粒状の、電気石はじめ各種アニオン発生物質、遠赤外線発生物質、磁力線発生物質など、各種の生理学的パラメーターの改善効果の期待できる機能性添加材を混入することによって、該RFID装置の装着中は、装着者の末梢血流量の改善、癒し、筋肉の凝りの加温治療効果による寛解などの各種の生理学的改善効果も期待できるなど、健康面での各種の改善・増進効果を付与しようとするものである。
【0007】すなわちこの発明は、搭載するリング状アンテナを、螺旋状またはサイン・カーブなどの波形に賦型して柔軟かつ伸縮可能にすると共に、該RFID装置一式を一体的に被覆・補強するための材料にはSBR、NBR、EPRなど各種の合成ゴム、天然ゴムはじめ、弾性シリコーン樹脂、ポリウレタン樹脂、可塑化ポリ塩化ビニール樹脂、EVA樹脂、EEA樹脂などの、各種の柔軟性かつ屈曲性、および/または伸縮性を有する樹脂の群から選んでなる、1種または2種以上の材料の混合材料として使用することができる。
【0008】これらの被覆・補強用材料には耐水性、耐久性に優れるものであることは勿論、安全性の高いものを選んで使用するのも勿論であるが、さらに外観の改善を兼ねて、該RFID装置全体が人体、特に皮膚のほかにも毛髪や下着などに、装着中の長時間にわたり直接、しかも乾燥状態のみでなく、時として汗やシャワーなどにより、湿潤状態において接触するものであるため、耐久性および耐水性に優れたものである必要があるが、さらにこの材料表面に対して安全性が高く、かつ美的にも優れた各種の色彩をもち、柔軟性および/およびまた伸縮性を有する合成樹脂ないし合成ゴム系塗料を用いて、1層または2層以上の多層の塗装を施して使用することも同様に望ましい。
【0009】この発明で使用することができる、樹脂状またはゴム状の被覆・補強材として使用することが出来る材料としては、天然ゴムはじめ、SBR、NBR、EPR等の架橋可能な各種の合成ゴム系材料の他、ゴム弾性を有するシリコーン樹脂、ポリエーテル系もしくはポリカーボネート系で、耐久性および耐水性に優れたポリウレタン樹脂等の、架橋可能な各種の合成樹脂材料、さらには常温においてゴム状弾性を有し、伸縮可能な可塑化ポリ塩化ビニール樹脂、EVA樹脂、EEA樹脂などの各種の熱可塑性樹脂類、およびこれらの各種の変性樹脂、またはこれら相互の混合物があげられるが、これら各種の被覆・補強用材料を化学的に変性し、またはこれら材料の2種以上の混合物として使用する場合は、優れた相溶性を有し、該装置製品成形後の本来の性質や機能を妨げない範囲で、変性または混合して使用することが必要である。
【0010】この発明で生理学的な改善効果を期待することができる機能性添加材として使用することができる、電気石はじめ各種のアニオン発生物質、遠赤外線発生物質、磁性材料などの各種の材料は、粉末状ないしは粒状にして、被覆・補強用ゴム系または合成樹脂系材料の中に混合し、分散して使用するものであるが、これら各種の材料の添加量については、目的とする生理学的改善効果を発揮するに十分な量とする必要があるが、これらの添加量が過剰になると、被覆・補強材として使用する樹脂状またはゴム状材料の柔軟性、屈曲性、ゴム弾性、伸縮性、強度、製品表面の感触などを著しく減退させることがあるため、一般にはこれら各種機能性添加材の添加量は、使用する各種の樹脂状ないしはゴム状材料に対して、50重量%程度以下の範囲で添加して使用する必要がある。
【0011】さらにはこれらの各種のゴムやゴム状樹脂に対して充填材として、補強、比重調節、色彩や感触の改善などの目的で、安全性の高い、耐久性および耐水性を有する有機もしくは無機物質の粉末、粒状物、もしくは繊維状物を添加して使用してもよいが、これらの充填材の使用量は、この発明における本来の機能や各種の性質を損なわない範囲で、一般には被覆・補強用材料として使用する各種のゴムまたは樹脂に対して、50重量%以下の範囲で、混合して使用することができる。
【0012】これらの各種の被覆・補強材、および/またはこれの表面を塗装するための塗料に対しては、さらに適量の安定剤、紫外線吸収剤、酸化防止剤、帯電防止剤、香料、防菌剤、防黴剤などを添加もしくは塗布して使用することができるのは勿論である。

[0003]
[Prior art]
Some IDs equipped with an antenna having a relatively short size have been put into practical use in the form of a card or the like. Even if it is in contact, there is an inconvenience that necessary information cannot be exchanged unless it is brought close to a distance of several tens of mm or less, and this situation is a wristwatch type ID device using a bar code. It was almost as inconvenient as it lacked.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to allow a distance between a conventional barcode and a reader such as a conventional IC card which is not much different from that of a reader when exchanging information. For example, the inventor of the present invention had to remove the IC card from his / her pocket or bag and contact or approach the reader unit for an automatic ticket-opening machine in a transportation facility, and the inventors of the present invention sought to address these issues. We worked diligently to resolve the point.
[0005]
As compared with a conventional IC card, an antenna having a loop shape and a larger loop diameter is formed as compared with a conventional IC card, and further, at least a flexible material is used for these antennas to impart flexibility. Along with that, it is more desirable to provide elasticity. As a means for that, the antenna to be mounted is formed into a spiral shape, or a sine curve, a triangular wave, or a rectangular wave, so that the antenna is softened. In addition to imparting flexibility and further elasticity, the resinous or rubbery material for covering and reinforcing has rubber-like elasticity and is softened to impart flexibility, and further imparts elasticity. This makes it easy to attach and detach, and also frees the inconvenience and discomfort experienced by the antenna being too long during mounting. .
Further, the coating / reinforcing material composition of the present invention has improved various physiological parameters, such as pulverized powder or granular, tourmaline, various anion-generating substances, far-infrared ray generating substances, and magnetic field generating substances. Various physiological improvements such as improvement of peripheral blood flow of the wearer, healing, and remission by heating treatment of muscle stiffness during wearing of the RFID device by mixing a functional additive which can be expected to be effective. It is intended to provide various health improvement / promotion effects such as expected effects.
That is, the present invention is to form a mounted ring-shaped antenna into a spiral shape or a sine curve or the like to make it flexible and extendable, and to cover and reinforce the RFID device as a whole. Materials include various kinds of synthetic rubber such as SBR, NBR, EPR, natural rubber, elastic silicone resin, polyurethane resin, plasticized polyvinyl chloride resin, EVA resin, EEA resin, etc. And / or a mixture of two or more materials selected from the group of resins having elasticity.

The entire RFID device is in direct contact with the human body, especially the skin, as well as the hair and underwear, for a long time during wearing, and not only in a dry state but also sometimes in a wet state due to sweat or shower. Therefore, it is necessary that the material has excellent durability and water resistance. However, the surface of the material has various colors which are highly safe and aesthetically excellent, and has flexibility and / or elasticity. It is also desirable to apply one or more layers of a multi-layer coating using a synthetic resin or synthetic rubber-based coating having properties.
Examples of the material which can be used as a resinous or rubbery coating / reinforcing material which can be used in the present invention include natural rubber, and various crosslinkable synthetic rubbers such as SBR, NBR and EPR. In addition to plastic materials, silicone resins with rubber elasticity, polyether-based or polycarbonate-based polyurethane resins with excellent durability and water resistance, such as various cross-linkable synthetic resin materials, and rubber-like elasticity at room temperature Various thermoplastic resins such as plasticized polyvinyl chloride resin, EVA resin, and EEA resin which can be stretched and stretched, and various modified resins thereof, or mixtures thereof, are used. When the reinforcing material is chemically modified or used as a mixture of two or more of these materials, it has excellent compatibility, Within a range which does not impair the inherent properties and functions after device product molding, it is necessary to use modified or in combination.
Various materials such as tourmaline, various anion-generating substances, far-infrared ray generating substances, and magnetic materials which can be used as a functional additive capable of expecting a physiological improvement effect in the present invention are: , Powdered or granulated, mixed and dispersed in rubber or synthetic resin material for coating and reinforcement, and the amount of these various materials added depends on the intended physiological It is necessary to make the amount sufficient to exhibit the effect of improvement, but if these added amounts are excessive, the flexibility, flexibility, rubber elasticity, elasticity of the resinous or rubbery material used as the covering / reinforcing material In general, the amount of these various functional additives is 50% by weight with respect to the various resinous or rubbery materials to be used, since the strength, strength, and feel of the product surface may be significantly reduced. It is necessary to use by adding in a range of not less degree.
Further, as a filler for these various rubbers and rubber-like resins, organic or organic materials having high safety, durability and water resistance are used for the purpose of reinforcing, adjusting specific gravity, and improving color and feel. Inorganic powders, granules, or fibrous materials may be added and used, but the amount of these fillers used is generally within the range not impairing the original function and various properties of the present invention. It can be mixed and used within a range of 50% by weight or less with respect to various rubbers or resins used as coating and reinforcing materials.
