JP 2005-157485 A JP 2007-026145 A

  However, in the IC tag using the above irreversible temperature fuse, the temperature fuse is directly incorporated in the antenna circuit. Therefore, when the IC tag is exposed to a temperature other than a predetermined temperature, the antenna circuit The resonance frequency remained unchanged, and the resonance frequency could not be restored. Therefore, when this IC tag is exposed to a temperature other than a predetermined temperature, it cannot be reused.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a non-contact type data receiving / transmitting body that can easily sense temperature and can be reused even after temperature sensing.

The inlet 11 and the heat-shrinkable base material 12 are joined via an adhesive material at one end 11b and 12b in the longitudinal direction, and the other parts are separated without being joined.

  Here, the joint between the inlet 11 and the heat-shrinkable base material 12 by the adhesive material is not made firmly, but the heat shrinkable base material 12 is temporarily fixed on the inlet 11 by the adhesive material. It is. That is, by applying an external force to the heat-shrinkable base material 12, the heat-shrinkable base material 12 is joined to the inlet 11 to such an extent that the heat-shrinkable base material 12 can be moved on the inlet 11.

The inlet 11 includes a base plate 14 having a rectangular shape in plan view, an antenna 15 and an IC provided on a surface (hereinafter referred to as “one surface”) 14 a of the base material 14 facing the heat-shrinkable base material 12 and connected to each other. It consists of a chip 16.
That is, the antenna 15 is disposed at a position facing the conductor 13 when the inlet 11 and the heat-shrinkable base material 12 are laminated.

The antenna 15 is opposed to each other and has a pair of radiating elements 15A and 15B each having a feeding point (portion connected to the IC chip 16) on the opposite side, and a short-circuit portion that short-circuits the vicinity of the feeding points of the radiating elements 15A and 15B. (Not shown).
The length (full length) of the antenna 15 corresponds to a half wavelength of the frequency (300 MHz to 30 GHz) of the ultra-high frequency band <UHF> and the microwave band that can be used for a non-contact IC module such as a non-contact IC card. It is the length to do. That is, the length (full length) of the radiation elements 15A and 15B is a length corresponding to a quarter wavelength.

  The conductor 13 is provided in a frame shape on the periphery of a portion other than the one end portion 12 b (that is, a portion not joined to the inlet 11) of the one surface 12 a of the heat-shrinkable base material 12.

Moreover, it is preferable that the adhesive 13 which joins the above-mentioned inlet 11 and the heat-shrinkable base material 12 to the surface 13a facing the inlet 11 of the conductor 13 is provided.
By providing the adhesive material on the conductor 13 in this manner, the conductor 13 can be temporarily fixed to the one surface 14a of the base material 14 by the adhesive material. Again, by applying an external force to the heat-shrinkable substrate 12, the heat-shrinkable substrate 12 can be moved to the extent that the heat-shrinkable substrate 12 can be moved on the inlet 11 (on one surface 14a of the substrate 14). Is temporarily fixed to one surface 14 a of the base material 14.

Further, the antenna 15 of the inlet 11 and the conductor 13 provided on the heat-shrinkable base material 12 are formed when the inlet 11 and the heat-shrinkable base material 12 are laminated as shown in FIG. It arrange | positions in the position which does not overlap in the thickness direction.
Here, the antenna 15 and the conductor 13 do not overlap in the thickness direction. The outer surface 15a of the antenna 15 and the inner surface 13b of the conductor 13 do not exist on the same plane (on the same line) in the thickness direction. Contains.

  As the heat-shrinkable substrate 12, a shrink film having a rectangular shape in a plan view that shrinks at a temperature of 70 ° C. or more is used. For example, a polyvinyl chloride shrink film or polypropylene shrink having a heat shrinkage rate of 15% or more at 70 ° C. Examples thereof include a film, a polyethylene shrink film, a polystyrene shrink film, a polyolefin shrink film, and a polyethylene terephthalate shrink film.

 The conductor 13 is formed by screen printing in a predetermined pattern using polymer type conductive ink on one surface 12a of the heat-shrinkable base material 12, or is formed by etching a conductive foil. It is made by metal plating.

  Examples of polymer-type conductive inks are those in which conductive fine particles such as silver powder, gold powder, platinum powder, aluminum powder, palladium powder, rhodium powder, carbon powder (carbon black, carbon nanotube, etc.) are blended in the resin composition Is mentioned.

If a thermosetting resin is used as the resin composition, the polymer type conductive ink becomes a thermosetting type capable of forming a coating film forming the conductor 13 at 200 ° C. or less, for example, about 100 to 150 ° C. A path through which electricity of the coating film forming the conductor 13 flows is formed when the conductive fine particles forming the coating film contact each other, and the resistance value of the coating film is on the order of 10 ⁻⁵ Ω · cm.
Further, as the polymer type conductive ink in the present invention, known ones such as a photo-curing type, a permeation drying type, and a solvent volatilization type are used in addition to the thermosetting type.

  The photocurable polymer type conductive ink contains a photocurable resin in the resin composition and has a short curing time, so that the production efficiency can be improved. Examples of the photocurable polymer conductive ink include, for example, a thermoplastic resin alone or a blend resin composition of a thermoplastic resin and a crosslinkable resin (especially a crosslinkable resin composed of polyester and isocyanate) and 60 masses of conductive fine particles. % Or more and 10% by mass or more of a polyester resin, that is, a solvent volatile type or a crosslinked / thermoplastic combined type (however, the thermoplastic type is 50% by mass or more), or a thermoplastic resin Or a blend resin composition of a thermoplastic resin and a crosslinkable resin (especially a crosslinkable resin composed of polyester and isocyanate), in which a polyester resin is blended in an amount of 10% by mass or more, that is, a crosslinkable type or a crosslinkable / heatable type A plastic combination type is preferably used.

Moreover, as conductive foil which makes the conductor 13, copper foil, silver foil, gold foil, platinum foil, aluminum foil, etc. are mentioned.
Furthermore, examples of the metal plating that forms the conductor 13 include copper plating, silver plating, gold plating, and platinum plating.

  As the substrate 14, a substrate made of a polyester resin such as polyethylene terephthalate (PET), glycol-modified polyethylene terephthalate (PET-G), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN); polyethylene (PE), polypropylene Base material made of polyolefin resin such as (PP); Base material made of polyfluorinated ethylene resin such as polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene; Made of polyamide resin such as nylon 6, nylon 6,6 Base material: Base material made of vinyl polymer such as polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer, polyvinyl alcohol, vinylon; polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, polyacryl Base material made of acrylic resin such as butyl; Base material made of polystyrene; Base material made of polycarbonate (PC); Base material made of polyarylate; Base material made of polyimide; Fine paper, thin paper, glassine paper, sulfate paper, etc. A substrate made of paper is used. Among these substrates, a substrate made of polyethylene terephthalate (PET), glycol-modified polyethylene terephthalate (PET-G), polyethylene naphthalate (PEN), or the like is preferable from the viewpoint of mechanical strength, dimensional stability, and solvent resistance. In view of transparency, processability, and cost, a substrate made of polyethylene terephthalate (PET) or glycol-modified polyethylene terephthalate (PET-G) is more preferable.

  The antenna 15 is formed on one surface 14a of the base material 14 by screen printing in a predetermined pattern using polymer-type conductive ink in the same manner as the conductor 13, or the conductive foil is etched. It is made by metal plating.

  The IC chip 16 is not particularly limited, and can be a non-contact type IC tag, a non-contact type IC label, or a non-contact type as long as information can be written and read in a non-contact state via the antenna 15. Anything applicable to RFID media such as an IC card can be used.

Next, with reference to FIGS. 1-3, the usage method and effect | action of the non-contact-type data transmission / reception body 10 are demonstrated.
2 and 3, the one end portion 11b of the inlet 11 and the one end portion 12b of the heat-shrinkable base material 12 shown in FIG.
In order to use the non-contact type data receiving / transmitting body 10, the inlet 11 and the heat-shrinkable base material 12 are laminated (overlapped). At this time, it is preferable to temporarily fix the heat-shrinkable base material 12 to the one surface 14a of the base material 14 with an adhesive material provided on the surface 13a facing the inlet 11 of the conductor 13.
At this time, the antenna 15 of the inlet 11 and the conductor 13 of the heat-shrinkable base material 12 are arranged at positions that do not overlap in the thickness direction, as shown in FIG.

  The non-contact type data receiving / transmitting body 10 is affixed to an article or the like in a state where the inlet 11 and the heat-shrinkable base material 12 are laminated in this manner, and is used for presence detection and identification.

When the article to which the non-contact type data receiving / transmitting body 10 is attached is exposed to a temperature environment of 70 ° C. or higher, the heat-shrinkable base material 12 contracts in the surface direction, and the conductor 13 is also surfaced accordingly. By contracting in the direction, for example, as shown in FIG. 2 or FIG. 3, the conductor 13 of the heat-shrinkable base material 12 overlaps the antenna 15 of the inlet 11 in the thickness direction.
Here, the “surface direction” is a direction along one surface 12 a of the heat-shrinkable base material 12.
Further, since the conductor 13 is made of a thin film provided on the one surface 12a of the heat-shrinkable base material 12, it can shrink following the heat shrinkage of the heat-shrinkable base material 12.

In FIG. 2, the inner surface 13b of the conductor 13 is in contact with the outer surface 15a of the antenna 15, that is, the outer surface 15a of the antenna 15 and the inner surface 13b of the conductor 13 are on the same plane in the thickness direction (the same On the line).
In FIG. 3, the antenna 15 and the conductor 13 are overlapped in the thickness direction.

When the conductor 13 of the heat-shrinkable base material 12 overlaps with the antenna 15 of the inlet 11 in the thickness direction, the non-contact type data receiving / transmitting body 10 transmits information to the IC chip 16 via the antenna 15 in a non-contact state. It becomes impossible to write and read.
This is because, when the conductor 13 and the antenna 15 overlap each other in the thickness direction, when the radio wave from the information writing / reading device is received on the one surface 14a side of the base material 14, the conductor 13 becomes the loop antenna. The conductor 13 receives the radio wave from the information writing / reading device, and only the conductor 13 generates an electromotive force due to the resonance action. Accordingly, since the antenna 15 does not receive radio waves, the non-contact type data receiving / transmitting body 10 cannot communicate.

  On the other hand, when the conductor 13 and the antenna 15 are overlapped in the thickness direction and the radio wave from the information writing / reading device is received on the other surface 14b side of the base material 14, the frequency at which the antenna 15 resonates. Since the wavelength is shifted, the non-contact type data receiving / transmitting body 10 cannot communicate.

As described above, according to the non-contact type data receiving / transmitting body 10, the heat-shrinkable base 12 contracts in the surface direction at a temperature equal to or higher than the heat-shrink temperature, whereby the conductor 13 of the heat-shrinkable base 12 becomes the antenna of the inlet 11. 15 overlaps in the thickness direction, information cannot be written to and read from the IC chip 16 via the antenna 15. Therefore, it is possible to grasp that the non-contact type data receiving / transmitting body 10 and the article to which the non-contact type data receiving / transmitting body 10 is applied are exposed to a temperature environment equal to or higher than the heat shrink temperature of the heat shrinkable base material 12 (for example, 70 ° C. or higher).
Further, since the heat-shrinkable base material 12 provided with the conductor 13 is merely joined to the inlet 11 via an adhesive material, the non-contact type data receiving / transmitting body 10 is once temporarily heat-shrinkable. Even if the heat shrinkable base material 12 is peeled from the inlet 11, the inlet 11 can be reused even when exposed to a temperature environment equal to or higher than the heat shrink temperature of the material 12.

  In addition, in this embodiment, although the conductor 13 illustrated the non-contact type data transmission / reception body provided in frame shape in the periphery of the one surface 12a of the heat-shrinkable base material 12, the non-contact type of this invention The data receiving / transmitting body is not limited to this. In the non-contact type data transmitting / receiving body of the present invention, the shape of the conductor is a shape that does not overlap with the antenna in the thickness direction when the inlet and the heat-shrinkable base material are laminated, and the heat Any shape may be used as long as it overlaps at least a part of the antenna in the thickness direction when the shrinkable base material contracts in the plane direction.

Further, in this embodiment, the non-contact type data receiving / transmitting body 10 provided with the inlet 11 having the antenna 15 made of a dipole antenna, one of which has a triangular plane shape, is illustrated. However, the non-contact type data receiving / transmitting body of the present invention is illustrated. Is not limited to this. In the non-contact type data transmitting / receiving body of the present invention, the antenna may be a dipole antenna or a meander dipole antenna, one of which has a triangular frame shape.
Moreover, in this embodiment, although the non-contact type data receiving / transmitting body in which the shapes of the base material 14 and the heat-shrinkable base material 12 of the inlet 11 are rectangular in plan view is illustrated, the non-contact type data receiving / transmitting device of the present invention is illustrated. The body is not limited to this. In the non-contact type data receiving / transmitting body of the present invention, the shapes of the inlet base and the heat-shrinkable base are appropriately set according to the use of the non-contact type data receiving / transmitting body.

(2) Second Embodiment FIGS. 4A and 4B are schematic views showing a second embodiment of the contactless data receiving / transmitting body of the present invention, where FIG. 4A is a perspective view and FIG. 4B is contactless data. It is sectional drawing which follows the DD line | wire of (a) when the two base materials which comprise a transmission / reception body are piled up.
In FIG. 4, the same components as those of the non-contact type data receiving / transmitting body 10 shown in FIG.

The non-contact type data receiving / transmitting body 20 of this embodiment is different from the non-contact type data receiving / transmitting body 10 of the first embodiment described above in that the inlet 11 on the side of the other surface 14b of the base material 14 is the inlet. 11 and the heat-shrinkable base material 12 are bonded to each other at one end portions 11b and 12b in the longitudinal direction via an adhesive material.
That is, the antenna 15 is disposed at a position not facing the conductor 13 when the inlet 11 and the heat-shrinkable base material 12 are laminated.

Also in this non-contact type data receiving / transmitting body 20, it is preferable that a surface 13 a facing the inlet 11 of the conductor 13 is provided with an adhesive material that joins the inlet 11 and the heat-shrinkable base material 12. .
By providing the adhesive material on the conductor 13 in this way, the conductor 13 can be temporarily fastened to the other surface 14b of the substrate 14 by this adhesive material. Again, by applying an external force to the heat-shrinkable substrate 12, the heat-shrinkable substrate 12 can be moved to the extent that the heat-shrinkable substrate 12 can be moved on the inlet 11 (on the other surface 14b of the substrate 14). Is temporarily fixed to the other surface 14 b of the base material 14.

Next, with reference to FIGS. 4-6, the usage method and effect | action of the non-contact-type data transmission / reception body 20 are demonstrated.
5 and 6, the one end 11b of the inlet 11 and the one end 12b of the heat-shrinkable base material 12 shown in FIG.
In order to use this non-contact type data transmitting / receiving body 20, the inlet 11 and the heat-shrinkable base material 12 are laminated (overlapped). At this time, it is preferable to temporarily fix the heat-shrinkable base material 12 to the other surface 14 b of the base material 14 with an adhesive material provided on the surface 13 a facing the inlet 11 of the conductor 13.
At this time, the antenna 15 of the inlet 11 and the conductor 13 of the heat-shrinkable base material 12 are arranged at positions that do not overlap in the thickness direction as shown in FIG.

  The non-contact type data receiving / transmitting body 20 is attached to an article or the like in a state where the inlet 11 and the heat-shrinkable base material 12 are laminated as described above, and is used for presence detection and identification.

  When the article to which the non-contact type data transmitting / receiving body 20 is attached is exposed to a temperature environment of 70 ° C. or higher, the heat-shrinkable base material 12 contracts in the surface direction, and the conductor 13 also has a surface. By contracting in the direction, for example, as shown in FIG. 5 or FIG. 6, the conductor 13 of the heat-shrinkable base material 12 overlaps the antenna 15 of the inlet 11 in the thickness direction.

In FIG. 5, the outer surface 15a of the antenna 15 and the inner surface 13b of the conductor 13 are on the same plane (on the same line) in the thickness direction.
In FIG. 6, the antenna 15 and the conductor 13 are overlapped in the thickness direction.

When the conductor 13 of the heat-shrinkable base material 12 overlaps the antenna 15 of the inlet 11 in the thickness direction, the non-contact type data receiving / transmitting body 20 transmits information to the IC chip 16 through the antenna 15 in a non-contact state. It becomes impossible to write and read.
This is because the frequency at which the antenna 15 resonates when it is intended to receive radio waves from the information writing / reading device on the one surface 14a side of the base material 14 with the conductor 13 and the antenna 15 overlapping in the thickness direction. Therefore, the non-contact type data receiving / transmitting body 10 cannot communicate.

  On the other hand, when the conductor 13 and the antenna 15 overlap each other in the thickness direction, when the radio wave from the information writing / reading device is received on the other surface 14b side of the base material 14, the conductor 13 becomes a loop antenna. The conductor 13 receives the radio waves from the information writing / reading device, and an electromotive force is generated only by the conductor 13 due to the resonance action. Accordingly, since the antenna 15 does not receive radio waves, the non-contact type data receiving / transmitting body 10 cannot communicate.

  On the other hand, when the conductor 13 and the antenna 15 are overlapped in the thickness direction and the radio wave from the information writing / reading device is received on the other surface 14b side of the base material 14, the frequency at which the antenna 15 resonates. Since the wavelength is shifted, the non-contact type data receiving / transmitting body 10 cannot communicate.

  Although it does not specifically limit as the housing | casing 31, Although the shape of the part (storage part) 31a which accommodates the laminated body of the inlet 11 and the heat-shrinkable base material 12 is substantially equal to the external shape of the laminated body is used. In this way, the inlet 11 and the heat-shrinkable base material 12 can be maintained without being deformed, so that the communication characteristics of the non-contact type data transmitter / receiver 30 are not deteriorated. In addition, the heat shrinkage of the heat shrinkable substrate 12 is not hindered.

  The material of the casing 31 is a polyester resin such as polyethylene terephthalate (PET), glycol-modified polyethylene terephthalate (PET-G), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN); polyethylene (PE), polypropylene (PP Polyolefin resins such as polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, etc .; polyamide resins such as nylon 6, nylon 6,6; polyvinyl chloride (PVC), ethylene-vinyl acetate Vinyl polymers such as copolymers, polyvinyl alcohol, vinylon; acrylic resins such as polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, polybutyl acrylate; polystyrene; Over preparative (PC); polyarylates; polyimides; and various paper.

  According to this non-contact type data receiving / transmitting body 30, since the inlet 11 and the heat-shrinkable base material 12 are laminated and housed in the housing 31, it is possible to use an adhesive material as in the first embodiment. The heat-shrinkable base material 12 can be temporarily fixed to the inlet 11. Moreover, since no adhesive is interposed between the inlet 11 and the heat-shrinkable base material 12, the heat-shrinkable base material 12 can be smoothly heat-shrinked.

In FIG. 8, the same components as those of the contactless data receiving / transmitting body 10 shown in FIG.
The non-contact type data receiving / transmitting body 40 of this embodiment is different from the non-contact type data receiving / transmitting body 10 of the first embodiment described above in that the inlet 11 and the heat-shrinkable base material 12 are laminated, and the clip 41 and 41 are temporarily fixed.

  According to this non-contact type data receiving / transmitting body 40, since the inlet 11 and the heat-shrinkable base material 12 are laminated and temporarily fastened with the clips 41 and 41, the inlet 11 and the heat-shrinkage as in the first embodiment. Since the adhesive material is not interposed between the conductive base materials 12, the heat-shrinkable base material 12 can be thermally contracted smoothly.

  In this embodiment, the non-contact type data receiving / transmitting body 40 in which the inlet 11 and the heat-shrinkable base material 12 are laminated and these are temporarily fastened with the clips 41 and 41 is illustrated. However, the non-contact type data of the present invention is illustrated. The transmission / reception body is not limited to this.
