Description

  The present invention relates to a functional label in which an IC module and an antenna circuit are provided on a sheet-like label base material so that information can be written and read. It is characterized in that it can be used for an EAS) system.

  In recent years, with the progress of the information society, many functional labels have been used in which an IC module and an antenna circuit are provided on a sheet-like label base material so that information can be written and read (for example, patents). Reference 1).

  Also, in recent years, in department stores, supermarkets, libraries, exhibition halls, etc., in order to prevent unauthorized removal or theft of articles, labels with magnetically sensitive objects are attached to the articles so that the articles are in the detection area. An electronic article monitoring (EAS) system that detects a change in the magnetic field by the magnetically sensitive object provided on the label and issues an alarm when passing through the apparatus is also employed (see, for example, Patent Document 2). .)

  Here, in the functional label as described above, since a magnetic material that is compatible with the EAS system is generally not used, it is not possible to prevent unauthorized removal and theft of the article using the EAS system, In addition, in the functional label as described above, since writing and reading of information is considered to be put into practical use in a frequency band around 900 MHz and a high frequency such as 2.54 GHz, electromagnetic waves are blocked by a shield such as an aluminum foil. It was easily shielded, and it was difficult to use it for the purpose of preventing the unauthorized removal of goods and theft.

  For this reason, recently, in the functional label as described above, in addition to the IC module and the antenna circuit, a magnetic sensitive object is provided on the label base material, or a thin film magnetic strip is used as the antenna. The one used is proposed (for example, refer to Patent Document 3).

  However, in the case where the magnetic sensing object is provided on the label base material in addition to the IC module and the antenna circuit as described above, the manufacturing is troublesome and the cost is increased by the provision of the magnetic sensing object, and the area is extra. There was a problem that was needed.

In the functional label in which the thin film magnetic strip is used as an antenna as described above, when the thin film magnetic strip is electrically connected to the IC module, the magnetic strip is turned up or down. Since it bends, it is necessary to previously bond the magnetic strip to the label base material over the entire surface, and there is a problem that it is difficult to manufacture the functional label and the cost is high.

  The present invention makes it possible to use an IC module and an antenna circuit on a label base material so that information can be written and read, and can also be used in an electronic article surveillance (EAS) system. Therefore, it is an object of the present invention to make it easy to manufacture and to reduce manufacturing costs.

  In the functional label according to the present invention, in order to solve the above-described problems, at least the IC module and the magnetic wire material are bonded to each other by a conductive adhesive on one side of the label base material.

  Here, in this functional label, when the IC module and the magnetic wire are bonded with the conductive adhesive as described above, the detection by the electronic article monitoring (EAS) system is appropriately performed. It is preferable that one magnetic wire is bonded to the IC module with a conductive adhesive, but a plurality of magnetic wires extending in different directions are bonded to the IC module with a conductive adhesive. It is also possible to make it.

  In the functional label, a release sheet may be provided via a pressure-sensitive adhesive layer on the surface of the label base material in which the IC module and the magnetic wire are joined by a conductive adhesive. preferable.

  In the functional label according to the present invention, since at least the IC module and the magnetic wire are bonded to each other by a conductive adhesive on one side of the label base as described above, the magnetic wire serves as an antenna circuit. In addition to fulfilling the role of a magnetic sensing object in an electronic article surveillance (EAS) system.

  As a result, in the functional label according to the present invention, by using the magnetic wire as an antenna circuit, various information can be written to and read from the IC module. Using the magnetism of the wire, an electronic signal monitoring (EAS) system can detect an electrical signal based on a magnetic field change and issue an alarm, thereby preventing unauthorized removal and theft of the article.

  In addition, since the functional label in the present invention uses a magnetic wire, it can be easily held on the label base material by bonding the magnetic wire to the IC module with a conductive adhesive, and a thin film. As compared with the case where a magnetic strip is used, its manufacture becomes easier.

  Further, in the functional label according to the present invention, when a release sheet is provided via a pressure-sensitive adhesive layer on the surface of the label base material in which the IC module and the magnetic wire are joined by a conductive adhesive as described above, The adhesive layer ensures that the IC module and the magnetic wire are held on the surface of the label substrate, and the release sheet is peeled off, and the functional label is attached to the article by the adhesive layer. In this case, since a rigid magnetic wire is provided in the vicinity of the IC module provided on the label base material, even when an impact is applied to the functional label, the impact is The IC module can be prevented from being broken by being received by the magnetic wire. In addition, when a magnetic strip made of a thin film is used instead of the magnetic wire, the magnetic strip made of a thin film may be broken by an impact with an object even if the IC module is not broken. However, such a problem is less likely to occur when a magnetic wire is used. Further, when the functional label is attached to the article as described above, the IC module and the magnetic wire are covered with the label base material, which also protects the IC module and the magnetic wire. become.

  Hereinafter, a functional label according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings. The functional label according to the present invention is not particularly limited to those shown in the following embodiments, and can be implemented with appropriate modifications within a range not changing the gist thereof.

  In the functional label in this embodiment, as shown in FIGS. 1 (A) and 1 (B), a conductive adhesive 11 using a silver paste or the like is provided on one side of a label substrate 10 made of a resin film. In this state, the IC module 12 is set on the adhesive 11, and one magnetic wire 13 is used, and one end of the magnetic wire 13 is set on the adhesive 11. Then, the conductive adhesive 11 was heated and solidified to electrically connect the IC module 12 and one magnetic wire 13 and to hold them on one side of the label substrate 10.

  Here, as the magnetic material used for the magnetic wire 13, various so-called soft magnetic materials whose magnetization state changes with a relatively weak external magnetic field can be used. For example, permalloy, sendust, Co— B system, Co-Fe-B system, Co-Fe-Ni-B system, Fe-Ni-Mo-B system, Fe-Ni-P-B system, Fe-Ni-B system, Fe-B system, Fe -Mo-B-based, Co-Fe-Mo-B-Si-based amorphous metal materials, Fe-Si-based, Ni-Fe-based metal materials exhibiting large Barkhausen jumps, oxides such as soft ferrite A material etc. can be used.

  In this embodiment, the magnetic wire 13 has a wire diameter of 150 μm. In addition, in order for the magnetic wire 13 to be appropriately held by the label substrate 10 without being bent arbitrarily, and for the IC module 12 to be protected by the magnetic wire 13, the wire diameter is It is preferable to use one having a thickness of about 40 μm to 500 μm. This is because when the wire diameter is smaller than 40 μm, the magnetic wire 13 is easily bent and easily broken by an impact. On the other hand, when the wire diameter is larger than 500 μm, when the functional label is affixed to an article, if the affixing surface is a curved surface, it becomes difficult to affix the entire surface, and the functional label Unevenness becomes large and handling becomes difficult.

  Then, as described above, after the IC module 12 and one magnetic wire 13 are electrically connected and held on one side of the label base 10, the adhesive layer 14 is provided on one side as shown in FIG. Using the formed release sheet 15, the release sheet 15 is attached to one side of the label substrate 10 provided with the IC module 12 and one magnetic wire 13 via the pressure-sensitive adhesive layer 14. did.

  And in sticking the functional label in this embodiment to the article | item 1, as shown in FIG. 3, the IC module 12 and the one magnetic wire 13 were provided from said peeling sheet 15 as mentioned above. The label substrate 10 was peeled off together with the pressure-sensitive adhesive layer 14, and the functional label thus peeled off was attached to the article 1 by the pressure-sensitive adhesive layer 14.

  When the functional label is affixed to the article 1 in this way, the rigid magnetic wire 13 is provided in the vicinity of the IC module 12 provided on the label base 10, so that an impact is applied to an object on the functional label. Even when it is applied, the impact is received by the magnetic wire 13 and the IC module 12 is prevented from being destroyed. When a magnetic strip made of a thin film is used in place of the magnetic wire 13, the magnetic strip made of a thin film is broken by an impact of an object even if the IC module 12 is not broken. This may impair the writing and reading of information on the functional label, or the detection of articles by an electronic article surveillance (EAS) system. Such a problem is less likely to occur when 13 is used. Further, when the functional label is affixed to the article as described above, the IC module 12 and the magnetic wire 13 are covered and protected by the label base material 10, and the IC module 12 and the magnetic wire are also protected by this. 13 is protected.

  In the functional label in this embodiment, the IC module 12 and one end of one magnetic wire 13 are attached to one side of the label base material 10 by the conductive adhesive 11. The number, direction, and the like of the magnetic wire 13 provided on the label base material 10 can be appropriately changed. For example, as shown in FIG. 4, the IC module 12 and one magnetic wire 13 are arranged on one side of the label base material 10. The intermediate part is joined with the conductive adhesive 11, or as shown in FIG. 5, it is bridged over a pair of conductive adhesives 11, 11 provided on one side of the label substrate 10. Attach the IC module 12 and attach one end of each of the magnetic wires 13 and 13 onto the different adhesives 11 and 11 so that the two magnetic wires 13 and 13 face in opposite directions. As shown in FIG. 6, the IC module 12 is attached so as to be bridged between a pair of conductive adhesives 11 and 11 provided on one side of the label substrate 10 as shown in FIG. The two magnetic wire rods 13 and 13 have an appropriate angle across 12 so that one end of each magnetic wire rod 13 and 13 is attached to and bonded to different adhesives 11 and 11. You can also.

  Here, as shown in FIG. 6, one side of each of the magnetic wires 13, 13 is arranged so that the two magnetic wires 13, 13 have an appropriate angle on one side of the label substrate 10 with the IC module 12 interposed therebetween. When the end of each is bonded to the IC module 12 by the conductive adhesive 11, the two magnetic wires 13 and 13 extend in different directions, so that electronic article monitoring (EAS) can be performed in various directions. ) The system detects properly.
