DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-contact data carrier having an IC chip as a main internal component and transmitting and receiving signals in a non-contact manner, and a method of manufacturing the same.

[0002]

2. Description of the Related Art A non-contact data carrier system includes a transponder called a non-contact data carrier attached to an article or the like, and an interrogator connected to a host.
It is characterized in that non-contact communication is performed between these transponders and the interrogator via transmission media such as magnetism, induction electromagnetic fields, and microwaves (radio waves). In this system, a transponder is attached to various articles, information about the articles is remotely read by an interrogator and provided to a host, thereby realizing information processing about the articles.

[0003] As an information transmission system of a non-contact data carrier system, an electromagnetic coupling system, an electromagnetic induction system, a microwave system, an optical communication system, and the like are generally known. Among these methods, in the electromagnetic coupling method, the electromagnetic induction method, and the microwave method, the energy of the transmission signal from the interrogator can be used as the driving power of the transponder. Since the transmission signal itself can be used as a drive source, there is no deterioration in response capability due to a decrease in battery output as compared with other similar systems that require a drive source such as a battery in the transponder. There is a great advantage that there is no limit on the use of the transponder due to battery life.

FIG. 3 shows an overall configuration of a contactless data carrier system. As shown in FIG. 1, the contactless data carrier system includes an interrogator 10 and a transponder (contactless data carrier) 20.

[0005] The interrogator 10 includes a main controller 11 for controlling the entire interrogator 10, an interface unit 12 for controlling input and output of data with the host device, and tag information received from the contactless data carrier 20. Read / store
A storage unit 13 such as a writable RAM, a signal conversion unit 14 that converts transmission information from a parallel signal to a serial signal, and converts a reception signal from the non-contact data carrier 20 from a serial signal to a parallel signal, For example, ASK (Amplitude Shift Keying) method, FSK
(Frequency Shift Keying) modulating section 15 for modulating a signal for transmission and demodulating section 16 for demodulating a received signal.
, A transmission antenna 17 and a reception antenna 18.

The transponder (contactless data carrier) 20
A main control unit 21 for controlling the entire non-contact data carrier 20, a storage unit 22 such as an EEPROM for storing tag information which does not require a power supply backup, converting transmission information from a digital signal to an analog signal, and an interrogator 10; A signal converter 23 for converting a received signal from an analog signal to a digital signal, a modulator 24 for modulating a transmission signal into a signal for transmission by an ASK method, an FSK method or the like, and a demodulator 25 for demodulating a received signal. , A transmission antenna 26, and a reception antenna 27.

The basic communication procedure of this contactless data carrier system is as follows. First, the interrogator 10
An inquiry signal for reading tag information from the non-contact data carrier 20 is transmitted. Contactless data carrier 20
Receives the interrogation signal when it enters the receivable range, and transmits the tag information stored in the storage unit 22 as a response signal. The interrogator 10 receives and decodes this response signal and sends it to the host device as tag identification information.

[0008] As described above, the transponder (contactless data carrier) is mainly composed of an antenna for transmitting and receiving signals to and from the interrogator and circuit components, and is usually designed in consideration of durability and environmental resistance. And a structure in which an internal component group such as an antenna and a circuit component is hermetically sealed with a resin or the like. As an antenna, a coil formed of a copper conductor is frequently used in terms of price and productivity, and as the circuit component, for example, an IC chip is formed by forming a copper circuit pattern and terminals on the surface of an epoxy board. Attached ones are common. Usually, two end lines of a coil formed of a copper wire having an outer diameter of 70 to 80 μm are connected to terminal portions of circuit components by welding or soldering. As a resin material for hermetically sealing these internal parts, thermoplastic resins such as vinyl chloride resin, polyethylene terephthalate resin, acrylonitrile / butadiene / styrene copolymer resin, or epoxy resin, phenol resin, silicone resin, etc. Thermosetting resin is used.

One use of such a non-contact data carrier is in the security field where it is attached to an article to protect it from fraud such as theft or forgery. For example, a non-contact data carrier is attached to a high-priced product at a large-volume retailer or the like, and a crime such as so-called shoplifting or theft, in which an unpaid product is taken out of the store, can provide a high economic effect. When implementing, a non-contact data carrier that stores tag information (for example, product name and price) of the product in a storage element is attached to the product to be protected by special mounting means, and it is installed at the entrance of the store. An interrogator is installed, and after receiving payment for the buyer, the store releases the non-contact data carrier and then delivers the product to the buyer. For contactless data carriers intended for such use, high reliability and durability that make it difficult for the buyer to arbitrarily remove or destroy it are first required. Development and improvement are also being promoted from such a viewpoint.

[0010]

In a highly information-oriented society in recent years, the object of defense by a contactless data carrier is not only the article itself as described above, but also the article itself. Rather, it is often the information of the article. For example, when the article is a vehicle running meter, information on the number of running distances is a target of defense. Therefore, it has been practiced to attach a non-contact data carrier to the meter case to prevent unauthorized rewinding.

[0011] Another example of a defense target is an electromagnetic record in, for example, rental electronic equipment. Electromagnetic recording means that information is recorded and stored on a certain medium by a method that cannot be recognized by human perception, such as an electronic method or a magnetic method, such as an IC memory, a magnetic tape or a magnetic disk. Pointed out.

For example, in the case of an electromagnetic record such as an IC memory, the presence or absence of fraudulent acts cannot be determined from the appearance. Therefore, information unique to the device such as a serial number is stored as tag information in a non-contact data carrier. It is going to be mounted on IC memory. If a legitimate IC memory with a non-contact data carrier is
Even if they are exchanged for fake or manipulated,
Since it is difficult to forge or falsify the unique tag information, an abnormality appears in the response signal to the interrogator. for that reason,
The exchange can be easily detected by the host device. Therefore, by mounting such a non-contact data carrier, unauthorized replacement can be prevented beforehand, and the damage caused by it can be minimized.

However, if the electronic device
When the C memory is taken out, the attached non-contact data carrier is improperly removed by any means, and the non-contact data carrier is re-installed in the forged or altered IC memory, and the non-contact data carrier mounted IC memory is returned to the device. No abnormality appears in the response signal. Therefore, the exchange cannot be detected by the host device, and the damage is increased.

The present invention has been made in view of such circumstances, and it is difficult to use it again when it is detached from an article after mounting, and it is a non-contact data carrier suitable for use in defense against fraud. Its purpose is to provide.

[0015]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a non-contact data carrier in the form of a flexible label, and when the carrier is to be attached to an adherend and then to be peeled off, an internal component is required. Is made damaged so that it cannot be reused.

That is, the contactless data carrier in the form of a label according to the present invention is characterized in that (a)
A circuit component including a storage element for storing information, an antenna for transmitting and receiving signals to and from an external device in a non-contact manner, and a lead wire portion for electrically connecting the antenna and the circuit component are substantially flush with each other. Internal parts, which are arranged on
(B) a first adhesive layer and a second adhesive layer sandwiching the internal component, (c) a surface substrate adhered outside the first adhesive layer, and (d) the second adhesive. A release liner attached to the outside of the layer is laminated and integrated into a sheet shape, and the main body portion composed of (a), (b), and (c) serves as the second adhesive layer. It is characterized in that it has flexibility that can be attached to the surface of the adherend through the intermediary.

Further, the label-like non-contact data carrier of the present invention is further characterized in that at least the conductive wire portion is made of a copper wire having an outer diameter of 5 to 60 μm. More preferably, the outer diameter is 20-4.
The range is 0 μm.

By selecting a conductor having such an outer diameter as described above, when the release liner is removed and the non-contact data carrier in the form of a label that has been once adhered is to be peeled off, the internal parts are damaged, and again. Even if it is attached, it causes communication failure and cannot be used.

That is, according to the label-type non-contact data carrier of the present invention, as set forth in claim 3, the adhesive force in which the conductive wire portion acts between the attached main body portion and the surface of the adherend. It is also characterized in that at least a portion of the conductive wire portion has a breaking strength that can be broken by a minimum external force against the wire portion.

In the present invention, a conductor having an outer diameter of less than 5 μm is not only expensive and costly, but also expensive.
It is not preferable because the wire is easily broken even during normal use.
If the outer diameter is larger than 60 μm, it is not preferable because the label is hardly broken even if it is bent during peeling of the label, and the size of the coil becomes large and the label becomes bulky. In the conductive wire portion according to the present invention, the coil may be formed of a copper wire having an outer diameter of 5 to 60 μm, and the two end wires may be used as the conductive wires as they are, or the two coils may be formed after forming the coil. A copper wire having an outer diameter of 5 to 60 μm may be connected to the end wire.

In the present invention, as the surface substrate, for example, a thermoplastic resin material such as polyethylene, polypropylene, polyester, or vinyl chloride resin, or a paper or synthetic paper having a thickness of 0.01 to 1 mm can be used. It is.

As the pressure-sensitive adhesive (pressure-sensitive adhesive) for forming the pressure-sensitive adhesive layer, for example, pressure-sensitive adhesives such as acrylic, rubber, polyester, and silicone can be used. Further, the kind of the pressure-sensitive adhesive used for the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer may be the same or different. The adhesive strength of the first adhesive layer and the second adhesive layer may be the same or different, but if they are different, the first adhesive layer is slightly more in view of the object of the present invention. It is preferable to set a lower value. The thickness of the first adhesive layer and the second adhesive layer is 1 to 500
μm is preferable, and more preferably 10-100 μm.
m.

In the present invention, the material of the release liner is not particularly limited, but a release paper in which a silicone resin, a fluororesin or the like is coated on the surface of a paper having a thickness of about 0.1 to 10 μm as a release agent is inexpensive. It can be suitably used.

According to a fourth aspect of the present invention, there is provided a circuit component including a storage element for storing information, an antenna for transmitting and receiving signals to and from an external device in a non-contact manner, and A method of manufacturing a label-shaped non-contact data carrier including an internal component in which a lead wire portion electrically connecting the circuit board is disposed on substantially the same plane, wherein After forming one adhesive layer,
The internal component is placed on the first adhesive layer in a predetermined arrangement, and then a second adhesive layer is formed on the internal component and the first adhesive layer, and then the second adhesive layer is formed. It is characterized in that a release liner is adhered on top and pressed to integrate into a sheet.

When the non-contact data carrier of the present invention manufactured as described above is mounted on a target article, first, the remaining main body portion from which the release liner has been removed is attached to the second body.
May be applied so that the pressure-sensitive adhesive layer is in contact with a predetermined surface of the target article.

The reason why it is difficult to reuse the label-like non-contact data carrier of the present invention once it has been applied will be described. In the label-type non-contact data carrier of the present invention, the surface area of the conductor or the circuit component among the internal components sandwiched between the two adhesive layers, that is, the contact area with the adhesive layer, is much higher than that of the coil antenna. Small. Therefore, if the non-contact data carrier is to be peeled off after it has been once adhered to the surface to be adhered, an external force that resists the adhesive force acting between the main body and the surface of the adhered material is applied. Will be added unevenly to each of the internal components. For example, when an attempt is made to peel off a loop coil antenna portion having a large surface area, an excessive force is applied to a conductor having a small surface area. For this reason, breakage such as disconnection or peeling of the soldering of the connection portion with the terminal portion of the circuit board is likely to occur in the conductive wire. In the label-shaped non-contact data carrier of the present invention, the outer diameter is 5-6.
Since a very thin conductive wire having a thickness of 0 μm is used, the probability of disconnection or peeling can be greatly increased. Therefore, even if you re-attach it, in most cases communication becomes impossible, and the response to the interrogator will be abnormal,
Fraud and malfunctions will be detected.

Thus, the non-contact data carrier of the present invention can be of a disposable type which cannot be reused when it is removed from the article after being mounted. Furthermore, since it is thin and lightweight and can be manufactured at low cost, it can be suitably used as a disposable non-contact data carrier for preventing fraud.
