Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact data transmitter / receiver and a method of manufacturing the same. 2. Description of the Related Art Conventionally, an information recording medium (R) such as a non-contact type IC tag capable of recording and erasing data by transmitting and receiving data in a non-contact state.
F-ID (RadioFrequency IDent)
A non-contact type data transmitter / receiver frequently used for the purpose of application (i.f. application)) has a configuration in which an antenna unit in which an IC chip is mounted on an antenna having a required pattern is arranged on a sheet-like base material. As described above, since data can be exchanged with a data reading device (referred to as a reader) at a remote position or the like and data recorded in advance on the non-contact type data transmitting / receiving body side can be read, As a specific example of the use, the non-contact type data transmission / reception body is used as a price tag or a product tag in general retail stores and the like. And
In such applications, the non-contact data transmitter / receiver records product information etc. as data in advance and uses it.
We need to deal with improper handling. For example, in a general retail store, the A's transmitter / receiver is stripped from the product of B to which the contactless data transmitter / receiver of A is attached,
There is a possibility that an unauthorized operation may be performed such that the C product is pasted on another C product to make the C product appear to be a B product. [0003] From this fact, it is conceivable as a countermeasure to prevent the function of the transmitting / receiving body from being destroyed when the non-contact type data transmitting / receiving body attached to an adherend such as a product is peeled off. However, the conventional basic non-contact data transmitter / receiver has an antenna unit formed on a film substrate and is covered with a resin, which causes structural destruction due to a careful and illegal stripping operation. Difficult to let. As a non-contact type data transmitter / receiver, a structure in which an antenna unit is formed on a paper base has also been proposed. However, even in this transmitter / receiver, the antenna unit is covered with paper or film, and the same caution is required. The improper stripping operation performed cannot cause structural destruction. In other words, these non-contact data transmitters and receivers are focused on improving the reliability of the transmitter and receiver itself,
It does not guarantee the security of the system using the transceiver by destroying the function of the transceiver. Accordingly, the present invention has been made in view of the above circumstances, and when the non-contact type data transmitting and receiving body is peeled off from the adherend, a part of the antenna unit or the antenna unit itself is left on the adherend side, so that the function of the transceiver is destroyed. An object of the present invention is to cause structural destruction, and to enhance security of a system using a non-contact type data transmitter / receiver. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has an adhesive layer provided on one side of a base material, and an IC chip mounted on an antenna made of a conductive material on the adhesive layer. A non-contact type data transmitter / receiver that is provided with an antenna unit provided and can be attached to an adherend, wherein the attachment layer is located at least in a part of an antenna unit corresponding region where the antenna unit is arranged. A strong adhesive portion having strong adhesiveness overlapping the antenna unit and a weak adhesive portion located on one surface of the base material in a region excluding the strong adhesive portion and having lower adhesiveness than the strong adhesive portion. It is an object of the present invention to provide a contact-type data transmitter / receiver to solve the above-mentioned problem. Next, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 to 6. In the figure, reference numeral 1 denotes a non-contact type data transmitter / receiver. The non-contact type data transmitter / receiver 1 is attached to various adherends on one side of a thin base material 2 made of paper, synthetic resin film or the like. The antenna unit 6 in which the IC chip 5 is provided on the antenna 4 made of a conductive material is located in the area of the adhesive layer 3. In the example of the non-contact data transmitter / receiver 1 shown in FIGS. 1 to 3, the antenna unit 6 located on the sticking layer 3 of the base material 2 has the IC chip 5 connected to the antenna 4 as described above, A separately formed interposer member 7 having an IC chip 5 is overlapped and joined to a terminal portion of the antenna 4 by a usual method. In this example, the operation of forming the antenna unit 6 itself is not performed on the adhesive layer 3, but
An integrated antenna 4 and interposer member 7 are arranged on the adhesive layer 3 in advance. The antenna 4 of the antenna unit 6 includes a conductive material pattern printing using a screen printing method, a conductive material pattern printing using an inkjet method, and a conductive material using a dispensing method on a peelable base material (not shown). And a conductive material pattern using an evaporation technique. The interposer member 7 has connection terminals corresponding to the respective ends of the antenna on a required base material, and the IC chip 5 is mounted so as to straddle the connection terminals. Then, the antenna unit 6 in which the IC chip 5 is provided on the antenna 4 is obtained by bonding the connection terminal of the interposer member 7 to the end of the antenna 4 via a conductive adhesive or the like. Thereafter, the antenna unit 6 is transferred onto the adhesive layer 3 so that the adhesive layer 3
Have been supported. In the adhesive layer 3, a part of the antenna unit corresponding area 8 where the antenna unit 6 is arranged is
The strong adhesive 9 is applied by applying an adhesive having a strong adhesive strength, and the adhesive strength of the strong adhesive 9 is weaker than the strong adhesive of the strong adhesive 9 over the entire area of one surface of the base material except for the strong adhesive 9. The adhesive layer 3 is divided into the strong adhesive section 9 and the weak adhesive section 10. Then, as shown in the drawing, the layout is set such that each loop of the antenna 4 traverses the strongly bonded portion 9 so as to cross. When the non-contact type data transceiver 1 is attached to the adherend by the adhesive layer 3 and then the non-contact type data transceiver 1 is peeled off, In addition, peeling occurs at the interface between the strong bonding portion 9 and the base material 2, and the strong bonding portion 9 remains on the adherend side, or causes the base material 2 to peel off in a layer, and a part of the base material 2 is adhered. It has an adhesive force to be left on the body side. The adhesive force of the weak adhesive portion 10 is the same as that of a normal adhesive, and the adhesive force of the adhesive constituting the strong adhesive portion 9 is weak when compared. That is, the non-contact type data transmitting / receiving body 1 is also appropriately affixed to the adherend in the portion where the weak adhesive portion 10 is located. As described above, the non-contact type data transceiver 1 has the antenna unit 6 on the sticking layer 3 and the sticking layer 3
This non-contact type data transmission / reception is manufactured by arranging a part of the antenna 4 on the strong bonding part 9 which is configured as a part of the antenna. The body 1 can be attached to the adherend. In the non-contact type data transmitter / receiver 1 having the above structure, since a part of the antenna 4 of the antenna unit 6 is located at a position corresponding to the strong bonding portion 9 in the adhesive layer 3, the strong bonding portion 9 and the antenna 4 And the corresponding portion of the second member are firmly adhered to each other. When the non-contact type data transmitter / receiver 1 is attached to an adherend and then peeled off from the adherend, a part of the antenna 4 corresponding to the strong adhesive portion 9 and the strong adhesive portion 9 are separated. The non-contact type data transmitter / receiver 1 remaining on the adherend side and peeled off as shown in FIG.
Is partially lost, and is destroyed without a data transmission / reception function. In addition, since the adhesive force in the strong adhesive part 9 is strong, the base material 2 may cause peeling in the layer or tear. Therefore, even if the stripped non-contact data transmitter / receiver 1 is attached to another adherend, data cannot be transmitted / received to / from the reader side. Data transmission and reception can be reliably prevented. In the above-described embodiment of the non-contact type data transmitter / receiver 1, a part of the antenna-corresponding region 8 in the adhesive layer 3 is used as the strong bonding portion 9, and the antenna 4 of the antenna unit 6 is used.
A part of the antenna 4 corresponding to the strongly bonded portion 9 remains on the adherend side when the non-contact type data transceiver 1 attached to the adherend is peeled off. Thus, the non-contact type data transmitter / receiver 1 is destroyed. However, the non-contact type data transceiver 1 of the present invention
Is not limited to this embodiment. FIGS. 4 to 6 show other examples, in which the strong bonding portion 9 is arranged over the entire area of the antenna unit corresponding region 8 as a pattern corresponding to the shape of the antenna unit 6. It is assumed to be 10. In this embodiment, since the antenna unit 6 is provided only on the strong bonding portion 9, the non-contact data transmitter / receiver 1 attached to the adherend is provided.
If this is removed, the strong bonding portion 9 and the antenna unit 6 will remain on the adherend side. Therefore, the stripped non-adhesive type data transmitter / receiver 1 itself does not have the antenna unit 6 (see FIG. 6), and even if this is attached to another adherend, data transmission / reception with the reader side is performed. Can not be performed, and transmission and reception of data with the non-contact type data transmitter / receiver that has been illegally stripped can be reliably prevented. In the embodiments shown in FIGS. 4 to 6, the antenna unit 6 does not use an interposer member. In the antenna unit 6 in this example, a bridge that straddles the loop portion of the antenna 4 formed on the peelable base material via an insulating material is connected to one end of the antenna 4 and extends between the bridge and the other end of the antenna 4. The antenna unit 6 is formed by mounting the IC chip 5 in this manner, and the antenna unit 6 thus formed is transferred from the release base material to the adhesive layer 3. In forming the antenna unit, any known method such as a method using wire bonding or a method using a solder ball can be used for connection between the IC chip and the antenna. For example, an adhesive layer may be interposed to establish and fix the connection between the IC chip and the antenna. As this adhesive layer, a known anisotropic conductive film (ACF (Anisotropic)
Conductive Film)) and the above-described anisotropic conductive paste (ACP (Anisotropic Co.)).
npastive)), insulating resin (NCP
(Non-Conductive Paste)), a double-sided adhesive tape or the like, and the coating method can be performed by a known method such as a dispensing method, a printing method, and a spraying method. Normally, bumps are formed on the connection terminals of the IC chip by metal electroplating, studs, electroless metal plating, and fixing of conductive resin. In response, energy such as heat, light, electromagnetic waves such as high frequency waves, or ultrasonic waves may be applied. After mounting, post-curing may be performed to further secure the fixing. After mounting, the whole or a part of the mounting part may be covered and protected with an underfill material such as a glove top material in order to protect the IC mounting part from physical or chemical impact. In manufacturing the non-contact type data transmitter / receiver 1, before the antenna unit 6 is transferred, a portion to be the strong bonding portion 9 and a weak bonding portion 10 in the antenna unit corresponding region 8 are formed on the base material 2 side. It is also possible to apply an adhesive having a different adhesive strength to each portion, or apply one kind of strong adhesive to the entire surface of one side of the base material, and then provide an adhesive force adjuster to the portion to be the customer adhesive portion 10. Good. In each of the illustrated examples, the strong bonding portion 9 and the weak bonding portion 10 are provided as solids by using a printing method or the like, but it is not always necessary to do so, and patterns such as dots and lines may be used. . Further, a combination of patterns such as points and lines may be used. The formation of the weakly bonded portion 10 may be performed as follows. For example, on the application surface of the pressure-sensitive adhesive or adhesive previously provided in a layer form on one surface of the base material 2, heating, electromagnetic wave irradiation (light irradiation, high frequency (Irradiation, electron beam irradiation) or the like is applied with a pressure-sensitive adhesive or an adhesive whose adhesiveness changes by giving a necessary adhesiveness suppressing condition for reducing the adhesiveness.
Then, after the transfer of the antenna unit 6 is performed, the required adhesion suppressing condition is applied (an adhesive or an adhesive whose adhesion is reduced by applying the required adhesion suppressing condition is applied to the entire surface. In this case, a required adhesiveness suppressing condition is given to a portion to be a weakly bonded portion), and the strongly bonded portion 9 and the weakly bonded portion 10 are separately formed on the adhesive layer 3. The form of each bonded portion formed in this way does not need to be continuous as a solid pattern, but is a pattern of dots, lines, and the like.
It is possible to use a combination of these patterns. According to the present invention described above, when the non-contact type data transmitter / receiver is peeled off after the non-contact type data transmitter / receiver is attached to the adherend, the strong adhesion portion and the antenna unit are removed. Since the corresponding part is firmly bonded, the strongly bonded part and the corresponding antenna unit part will remain on the adherend side, and the peeled non-contact type data transceiver will function. No longer. Therefore, even if the peeled-off non-contact data transmitter / receiver is attached again to another adherend, data cannot be transmitted / received to / from the reader, and the illegally-peeled non-contact data transmitter / receiver cannot be transmitted / received. Data transmission to and from the transmitter and receiver can be reliably prevented, and the security of a system using the non-contact type data transmitter and receiver can be enhanced.
