Description

Description Security label Technical field

The present invention relates to a security label, and more particularly to, for example, a security label for attaching an alarm device for notifying illegal removal to a product or the like, and issuing an alarm when the alarm device is removed illegally.

Background art

In recent years, theft and illegal removal of goods such as exhibits and merchandise have become a major problem at exhibition halls, supermarkets, and department stores. As a way to prevent this, an article monitoring system using self-sounding tags is promising.

As an alarm device for preventing such theft of a product or the like, for example, an anti-theft tag disclosed in Japanese Patent Application Laid-Open No. Heisei 9-245273 is used. This anti-theft tag T has a circuit as shown in FIG. The anti-theft tag T is attached to a product or the like by a conductive wire W. At the entrance of the store, a transmitter for transmitting a predetermined signal is provided. When trying to take out a product to which the anti-theft tag T is attached, a resonance consisting of the inductance L 1 and the capacitance C 2 occurs. The circuit resonates with the signal from the oscillator, and the buzzer BUZ issues an alarm.

As shown in FIG. 24, the conductive wire W is attached to the anti-theft tag T in a loop shape, and one end thereof is detachably formed. This conduction wire The wire W is passed through the handle of the bag B, for example, and one end of the conductive wire W is locked to the anti-theft tag T. Here, if the conductive wire W is cut and the anti-theft tag T is removed so that an alarm is not generated by the signal of the oscillation device, the disconnection of the conductive wire W is detected, and an alarm is issued by the buzzer BUZ. . In this way, the buzzer BUZ issues an alarm even if you try to take the product with the anti-theft tag T out of the store or illegally remove the anti-theft tag T.

When a customer purchases a product, for example, by unlocking the conducting wire W by inserting a key into the keyhole formed in the anti-theft tag T, the reset switch RS is conducted and no alarm is issued. It is possible to release the opening of the conducting wire W.

However, in the past, since the anti-theft tag was attached by entanglement of the conductive wire with the handle of the article, the conductive wire was used near the anti-theft tag by using other conductors or by directly bypassing. If a short circuit occurs, there is a problem that an alarm will not be issued even if the conductive wire is cut off beyond the short circuit. In addition, in the case of an article having a flat surface without a handle or the like, there is a problem that an anti-theft tag using a conductive wire cannot be attached.

Therefore, a main object of the present invention is to provide a security device having a structure in which an anti-theft tag can be attached to an article having a flat surface, and it is difficult to illegally remove the anti-theft tag without issuing an alarm. It is to provide a bell. Disclosure of the invention

The present invention relates to a sheet-like base material, two conductive pads formed in an intermediate portion on one surface of the base material, and one of the base materials so as to connect the two pads. A conductive layer formed on the surface, an adhesive layer formed on the other surface of the base material, and an easily breakable portion formed near the conductive layer to facilitate breaking the base and the conductive layer.

Between the orbital part of the layer And a cut formed in the base material or the conductor layer.

Further, a release layer having low adhesion to the adhesive may be formed on the conductor layer and the base material such that at least a part of the pad and the electrode layer is exposed.

In addition, a concealing layer for concealing the conductor layer is formed on the conductor layer and the base material so that the pad and the electrode layer are exposed, and the separation layer having weak adhesiveness to the adhesive is formed on the concealment layer. A mold layer may be formed.

An alarm device is connected to two pads formed on one side of the base material or to two pads and electrode layers formed on one side of the base material, and is formed on the other side of the base material The security label is attached to the article by the adhesive layer. This security label has an easily breakable part to make it easy to break the base material and the conductor layer, so if you try to remove the security label or remove the alarm device, the base material and the conductor layer will be damaged. Break. At this time, the disconnection of the conductor layer is detected by the alarm device, and an alarm is issued.

The easily breakable portion can be constituted by a cut formed in the base material. At this time, by forming a cut inward from the outer peripheral portion of the base material, when the security label is to be peeled, the base material breaks from the cut and the conductor layer also breaks. Further, by forming a cut in the base material between the pad forming portion and the circling portion of the conductor layer, when an attempt is made to lift the alarm device connected to the pad, the circling of the pad forming portion and the conductor layer is prevented. The base material breaks with the part. At the same time, the conductor layer is broken and an alarm is issued by the alarm device.

FIG. 1 is a front view showing an example of the security label of the present invention, FIG. 2 is an end view and FIG. 3 is a rear view. The security label 10 includes a sheet-like base material 12. As a material of the base material 1.2, for example, a thermoplastic film such as polystyrene, polyvinyl chloride, acrylic, AS resin, ABS resin, polyacetal, and polyacrylonitrile is used. The base material 12 includes a substantially rectangular intermediate portion 12a, and ends 12b and 12c wider than the intermediate portion 12a are formed on both sides thereof. On one surface of the intermediate portion 12a, two pads 14a and 14b are formed. These pads 14a and 14b are formed of a conductive material into a shape such as a rectangle. The shapes of the pads 14a and 14b may be formed in a shape other than a rectangle such as a circle. The conductor layer 16 is formed so as to connect these pads 14a and 14b. The conductor layer 16 is formed so as to extend from one pad 14 a to the end 12 b, circulates on the end 12 b, and extends from the middle 12 a to the other end 1 b. It is formed to extend to 2c. Further, the conductor layer 16 is connected to the pad 14b so as to go around on the end 12c. The pads 14 a and 14 b and the conductor layer 16 are formed by thermally transferring a conductive transfer foil such as a rubber ribbon to the base material 12.

Further, a plurality of cuts 18 are formed on the outer peripheral side of the ends 12 b and 12 c of the base material 12. These cuts 18 are formed so as to extend inward from the ends of the ends 12 b and 12 c. In addition, intermittent cuts 20 are formed on the ends 12 b and 12 c of the intermediate portion 12 a, respectively. The cut 20 is formed along the width direction of the intermediate portion 12a. In addition, intermittent cuts 22 are formed on the intermediate portion 12a side of the ends 12b and 12c. The cut 22 is formed substantially parallel to the cut 20. These cuts 20 and 22 are formed between the portions where pads 14a and 14b are formed and the portions around conductor layer 16 on ends 12b and 12c. Also, An X-shaped cut 24 is formed in the base material 12 between the cut 22 and the surrounding portion of the conductor layer 16.

An adhesive layer 26 is formed on the other surface of the substrate 12. The adhesive layer 26 is formed by applying, for example, an acryl-based adhesive or a urethane-based adhesive. On the adhesive layer 26, a release paper 28 is temporarily attached. A linear cut 30 is formed in the release paper 28 at a position substantially corresponding to or close to the cut 20 formed in the base material 12.

To produce the security label 10, a pad 14 a is formed by transferring a conductive transfer foil such as carbon onto one surface of a film large enough to obtain a plurality of substrates 12. , 14b and a plurality of conductor layers 16 are formed. Further, an adhesive layer 26 is formed on the other surface of the film, and a release paper 28 having substantially the same size as the film is temporarily attached thereon. Then, the film and the release paper 28 are punched into the shape of the base material 12 so as to include the pads 14 a and 14 b and the conductor layer 16. Cuts 18, 20, 22, 24 are formed on the base material 12 obtained in this manner by die cutting or the like. The breaks 18, 20, 22, 24 are formed so as not to extend over the conductor layer 16, but if the conductor layer 16 is continuous, the breaks 18, 20, 24, A part of 22 and 24 may extend over the conductor layer 16. Further, a cut 30 is formed in the release paper 28 by die cutting or the like. Before the film is punched into the shape of the substrate 12, cuts 18, 20, 22, 24 may be formed in the film, and cuts 30 may be formed in the release paper 28.

For example, an anti-theft tag 50 as shown in FIG. 4 is attached to the security label 10 as an alarm device. The anti-theft tag 50 includes a case 52 and has a circuit inside as shown in FIG. A recess 52 a is formed in the center of the outer surface of the case 52. You. The concave portion 52 a is formed in a shape in which the intermediate portion 12 a of the security label 10 is fitted. Then, two terminal electrodes 54 a and 54 b are formed in the concave portion 52 a. These terminal electrodes 54 a and 54 b are formed at intervals corresponding to the pads 14 a and 14 b on the base material 12. These terminal electrodes 54a and 54b are connected to the terminals to which the conductive layer 16 corresponding to the conductive wire W is connected via the pads 14a and 14b in the circuit shown in FIG. Become.

Further, a hinge portion 56 is formed at one end of the case 52, and a holding plate 58 is formed so as to extend from the hinge portion 56. The holding plate 58 is formed so as to be rotatable around the hinge portion 56. Further, a fixing claw 60 is formed at the tip of the pressing plate 58. A fixing portion 62 having a fitting portion 62 a for fitting the fixing claw 60 and fixing the holding plate 58 is formed at the other end of the case 52. Note that the fixing claw 60 and the fixing portion 62 are merely examples, and other structures may be employed as long as the holding plate 58 can be fixed.

A security label 10 is attached to the anti-theft door 50. At this time, the recessed part of the case 52 is set so that the middle part 12 a of the security label 10 faces the release paper 28 side of the security label 10 and the inside of the holding plate 58 of the anti-theft tag 50. The pads 14a, 14b are fitted to the 52a, and the pads 14a, 14b are connected to the terminal electrodes 54a, 54b. In this state, the holding plate 58 is closed, and the fixing claw 60 is fitted into the fitting portion 62 a of the fixing portion 62 of the case 52. As a result, the security label 10 is fixed to the anti-theft tag 50, and the conductor layer 16 is connected between the terminal electrodes 54a and 54b.

The security label 10 attached to the anti-theft tag 50 is attached to the surface of an article 100 such as a product as shown in FIG. At this time As shown in FIG. 6, the release paper 28 temporarily attached to the ends 12 b and 12 c of the base material 12 is peeled off, and the other surface of the ends 12 b and 12 c is removed. The security label 10 is attached to the article 100 by the adhesive layer 26 formed on the article 100. In addition, since the cut 30 is formed in the release paper 28, the release paper 28 temporarily attached to the intermediate portion 12a of the base material 12 remains, and this portion is the anti-theft tag 5. It is held down by the 0 holding plate 5 8. The anti-theft tag 50 is attached with a security label 10 so that the pressing plate 58 faces the article 100.

A gate or the like for transmitting a predetermined signal is provided at the entrance of the store where the article 100 is placed, and when the anti-theft tag 50 passes, the buzzer BUZ of the anti-theft tag 50 issues an alarm It has been emitted. Therefore, if the article 100 is taken out of the store with the anti-theft tag 50 attached, it can be detected by the alarm of the anti-theft tag 50. Also, if the conductor layer 16 is broken between the pads 14a and 14b of the security label 10, the anti-theft tag 50 will generate an alarm.

In the security label 10, the cuts 18, 20, 22, 24 are formed in the base material 12, so that when the security label 10 is to be peeled off from the article 100, 1 and 2 are easily broken. That is, these cuts 18, 20, 22, 24 are formed easily breakable portions. Therefore, if the security label 10 attached to the article 100 is to be peeled off from the end portions 12b and 12c, the base material 12 is broken from the cut 18 and the conductor layer 16 is formed. When the substrate 12 breaks to the point, the conductor layer 16 also breaks. Then, when the conductor layer 16 is broken, the buzzer BUZ of the theft prevention evening 50 issues an alarm.

Also, if the anti-theft tag 50 is lifted and the security label 10 is to be peeled off from the middle portion 12 a side of the base material 12, intermittent cuts 20, The base material 12 breaks from 22 and the conductor layer 16 also breaks. Further, the base material 12 is easily broken by the X-shaped cuts 24, and the conductor layer 16 is also easily broken. When the conductor layer 16 is broken, the buzzer BUZ of the anti-theft tag 50 issues an alarm.

As described above, if the security label 10 is illegally peeled off from the article 100, the conductor layer 16 is easily broken, and an alarm is issued. When the security label 10 is attached to the article 100, the terminal electrodes 54a and 54b of the anti-theft tag 50 and the pads 14a and 14b of the security label 10 are hidden. Therefore, it is difficult to short-circuit the conductor layer 16 near the terminal electrodes 54a and 54b. Therefore, it is difficult to remove the anti-theft tag 50 from the article 100 while the conductor layer 16 is short-circuited.

Adhesive tape or the like is stuck on the ends 12b and 12c of the base material 12 to reinforce the base material 12 so that it does not break from the cut 18 and peel off the security label 10 It is possible. Therefore, as shown in FIG. 7, silicon or the like is printed on the end portions 12 b and 12 c of the base material 12 and the conductor layer 16 formed thereon, and the adhesive 12 On the other hand, a release layer 32 having weak adhesion may be formed. By forming such a release layer 32, an adhesive tape or the like is not strongly adhered on the ends 12 b and 12 c of the base material 12, and the ends 12 b and 12 c Cannot be reinforced. Note that the release layer 32 may be formed not only on the ends 12 b and 12 c but also on the intermediate part 12 a. In this case, the pads 14 a and 14 b are exposed. It is formed so that. In addition, as shown in FIG. 8, a concealing layer 34 may be formed in order to conceal the conductor layer 16 formed on the ends 12 b and 12 c of the base material 12. In this case, the concealing layer 34 is formed on the end portions 12 b and 12 c of the base material 12 and the conductor layer 16 formed thereon. Then, the release layer 32 is formed on the concealing layer 34. The concealing layer 34 is made to have the same color as the conductor layer 16, for example. Formed. Of course, the concealing layer 34 may be not only the same color as the conductor layer, but also a different color, or may be a pattern or the like to hide the conductor layer 16. By forming such a concealing layer 34, the conductive layer 16 can be hidden from the surface of the security label 10 attached thereto, and the structure of the conductive layer 16 can be hidden from the surface of the security label 10. Can be kept secret. Such a concealing layer 34 and a release layer 32 may be formed not only at the end portions 12b and 12c of the base material 12 but also at the intermediate portion 12a. The pads 14a and 14b are formed so as to be exposed.

Further, it is not necessary to form the adhesive layer 26 on the entire surface of the other side of the substrate 12, and as shown in FIG. 9, the adhesive layer 26 is formed only on the ends 12 b and 12 c of the substrate 12. 6 may be formed. That is, it is not necessary to form the adhesive layer 26 on the intermediate portion 12a pressed by the pressing plate 58 of the anti-theft tag 50. In this case, the release paper 28 may not be formed in the intermediate portion 12a. Of course, a continuous release paper 28 from one end 12b to the other end 12c may be temporarily attached. At this time, since the adhesive layer 26 is not formed on the intermediate portion 12a, all the release papers 28 need only be peeled at the time of use, and it is not necessary to form a cut 30 in the release paper 28. Absent.

Further, as shown in FIG. 10, curved intermittent cuts 36 a and 36 b are formed between the portions where the pads 14 a and 14 b are formed and the portion around the conductor layer 16. It may be formed. These cuts 36 a and 36 b are formed on the intermediate portion 12 a side of the end portions 12 b and 12 c of the base material 12. Here, the cut 36 a is a cut curved toward the outside of the base material 12 (the center of each cut is located outside the base material 12 from both ends of each cut). b is a cut curved toward the inside of the base material 12 (the center of each cut is located inside the base material 12 from both ends of each cut). And off The cut 36a is formed outside the ends 12b, 12c, and the cut 36b is formed on the middle 12a side of the ends 12b, 12c. These cuts 36a and 36b are alternately formed such that their ends are close to each other. A cutout 36a curved outward is arranged at the outermost part of the base material 12 in the width direction. In this example, the X-shaped cut 24 shown in FIG. 1 is not formed.

In the security label 10 having such cuts 36a and 36b, when the anti-theft tag 50 attached to the article 100 is lifted and the security label 10 is to be peeled off, the cut 3 6 The substrate 12 breaks between the ends of a and 36b, and the conductor layer 16 also breaks. As a result, an alarm is issued by the BUZZU BUZ at 50 in the anti-theft evening. Since the cutout 36a that is curved outward is formed at the outermost part in the width direction of the base material 12, the anti-theft tag 50 is positioned at the outermost part of the base material 12 when the tag 50 is lifted. The base material 12 is easily broken starting from the arranged cut 36a.

Since the cuts 36 a and 36 b are arranged such that their ends are close to each other, the cuts 36 a and 36 b are also formed in the conductor layer 16. Therefore, in order to prevent the conductor layer 16 from being divided by the cuts 36a, 36b, the conductor layer 16 where the cuts 36a, 36b are formed has ends 12a, 12b. It is formed so as to have a larger width than the upper orbital portion. With such a width, the conductor layer 16 can be continuous between the adjacent ends of the cuts 36a and 36b.

When such a security label 10 is used, a short circuit between the two pads 14a and 14b can be achieved by applying a conductive liquid such as salt water, or a wire can be secured. It is conceivable that the two pads 14a and 14b are short-circuited by inserting them into the label 10, and the security label 10 is peeled off. In this way, two packages By shorting between the nodes 14a and 14b, it is possible to peel off the label 10 without an alarm being issued.

Therefore, it is conceivable to use an anti-theft tag that can generate an alarm even if the two pads 14a and 14b are short-circuited in the label 10 by applying a conductive liquid or the like. Can be In such a case, a security label having a structure that can be used for such an anti-theft tag is required.

FIG. 11 is a front view showing an example of a security label having such a structure, FIG. 12 is an end view of the security label, and FIG. 13 is a rear view thereof. The security label 10 has a structure similar to that of the security label shown in FIG. 10, but further includes another electrode layer.

On one surface of the intermediate portion 12a of the base material 12, two pads 14a and 14b are formed. These pads 14a and 14b are formed of a conductive material into a rectangular shape or the like. The pads 14a and 14b may be formed in any shape other than a rectangle such as a circle. The conductor layer 16 is formed so as to connect the pads 14a and 14b. The conductor layer 16 is formed so as to extend from one pad 14 a to the end 12 b, and circulates on the end 12 b, from the intermediate part 12 a to the other end 12 It is formed to extend to c. Further, the conductor layer 16 is connected to the pad 14b so as to go around on the end 12c.

Further, an electrode layer 40 is formed on one surface of the base material 12 at a distance from the pads 14 a and 14 b and the conductor layer 16. The electrode layer 40 is formed so as to pass between the two pads 14 a and 14 b, and is formed so that both ends thereof extend in the longitudinal direction of the base material 12. That is, the electrode layer 40 is formed in an H shape, and an intermediate portion thereof is arranged between the pads 14a and 14b. These pads 14a and 14b, conductor layer 16 and electrode layer 40 For example, it is formed by heat-transferring a conductive transfer foil such as a heat transfer ribbon to the substrate 12.

Further, a plurality of cuts 18 are formed on the outer peripheral side of the ends 12 b and 12 c of the base material 12. These cuts 18 are formed so as to extend inward from the edges of the ends 12b and 12c. In the base material 12, curved intermittent cuts 36a and 36b are formed. These cuts 18 and cuts 36a and 36b are formed in the same shape as the security label shown in FIG.

An adhesive layer 26 is formed on the other surface of the base material 12, and a release paper 28 is temporarily attached thereon. In the release paper 28, a linear cut 30 is formed at a position corresponding to or close to the intermediate portion 12 a and the end portions 12 b and 12 c of the base material 12. .

To produce the security label 10, a pad 14 a, 14 is formed by transferring a conductive transfer foil on one side of a film having a size capable of obtaining a plurality of substrates 12. b, A plurality of conductor layers 16 and electrode layers 40 are formed. Further, an adhesive layer 26 is formed on the other surface of the film, and a release paper 28 having substantially the same size as the film is temporarily attached thereon. Then, the film and the release paper 28 are punched into the shape of the base material 12 so as to include the pads 14a and 1b, the conductor layer 16 and the electrode layer 40. Cuts 18, 36 a, 36 b are formed in the base material 12 thus obtained by die cutting or the like. Further, a cut 30 is formed in the release paper 28 by die cutting or the like. Before punching the film into the shape of the substrate 12, cuts 18, 36 a, 36 b may be formed in the film, and cuts 30 may be formed in the release paper 28.

For example, an anti-theft tag 70 as shown in FIG. 14 is attached to the security label 10 as an alarm device. This anti-theft tag 7 Numeral 0 includes the case 52 similarly to the anti-theft tag shown in FIG. 4, and a concave portion 52a is formed in the center of the outer surface of the case 52. The concave portion 52 a is formed in a shape in which the intermediate portion 12 a of the security label 10 is fitted. Then, three terminal electrodes 54 a, 54 b and 54 c are formed in the recess 52 a. These terminal electrodes 5 4 a, 5 4 b, and 5 4 c are arranged such that when the intermediate portion 12 a of the security label 10 is fitted into the concave portion 52 a, the pad 14 a , 14 b and the electrode layer 16.

Further, a hinge portion 56 is formed at one end of the case 52, and a holding plate 58 is formed so as to extend from the hinge portion 56. The holding plate 58 is formed so as to be rotatable around the hinge portion 56, and the fixing claw 60 at the tip of the holding plate 58 is fitted into the fitting portion 62 a of the fixing portion 62. The holding plate 58 is fixed.

In the anti-theft tag 70, for example, a circuit as shown in FIG. 15 is formed. In this circuit, a normally open contact NO connected to the input section in the IC is added as compared with the circuit shown in FIG. Here, the terminal electrodes 54a, 54b, 54c of the antitheft tag 70 correspond to the terminals connected to the conductor layer 16 and the terminals connected to the normally open contact N〇. It is. The terminal electrode 54a is connected to, for example, a common terminal of the conductor layer 16 and the normally open contact NO. The input side of the conductor layer 16 is connected to the terminal electrode 54b. Further, the input terminal side of the normally open contact N〇 is connected to the terminal electrode 54 c at the center.

In this circuit, the input section in the IC detects breakage of the conductor layer 16 and short circuit of the normally open contact NO. The conductor layer 16 in the circuit shown in FIG. 15 corresponds to the conductive wire W in the circuit shown in FIG. In addition, normally open contact NO indicates pad 14a, 14b or It shows a gap between the body layer 16 and the electrode layer 40. Therefore, the input section detects breakage of the conductor layer 16 and short-circuit between the pads 14a, 14b or the conductor layer 16 and the electrode layer 40. Further, the reset input section prevents an alarm from being issued even if the conductor layer 16 is broken.

The security label 10 is attached to the anti-theft tag 70. At this time, the case 5 2 is placed so that the middle part 12 a of the security label 10 faces the release paper 28 side of the security label 10 and the inside of the holding plate 58 of the anti-theft tag 50. And the pads 14a and 14b are connected to the terminal electrodes 54a and 54b. Further, the electrode layer 40 is connected to the terminal electrode 54c. In this state, the holding plate 58 is closed, and the fixing claw 60 is fitted into the fitting portion 62 a of the fixing portion 62 of the case 52. Thereby, security label 10 is fixed to anti-theft tag 70, and conductor layer 16 is connected between terminal electrodes 54a and 54b.

The security label 100 attached to the anti-theft tag 70 is attached to the surface of an article 100 such as a product as shown in FIG. At this time, as shown in FIG. 17, the release paper 28 temporarily attached to the ends 12 b and 12 c of the base material 12 is peeled off, and the ends 12 b and 12 c The security label 10 is adhered to the article 100 by the adhesive layer 26 formed on the other surface of the article 100. Since the cut 30 is formed in the release paper 28, the release paper 28 temporarily attached to the intermediate portion 12a of the base material 12 remains, and this portion is the anti-theft tag 70. It is held by the holding plate 5-8. The anti-theft tag 50 is attached with a security label 10 so that the holding plate 58 faces the article 100.

Even with such an anti-theft tag 70, if the anti-theft tag 70 is attached and passed through a gate provided at the entrance of the store, the anti-theft tag 70 Can be detected by the alarm. Also, if the conductor layer 16 is disconnected between the pads 14a and 14b of the security label 10, the anti-theft tag 70 will generate an alarm.

In this security label 10, the cuts 18, 36 a, 36 b are formed in the base material 12, so that when the security label 10 is to be peeled off from the article 100, 1 2 is easily broken. In other words, the portions where these cuts 18, 36 a, 36 b are formed are easily breakable portions. Therefore, if the security label 10 affixed to the article 100 is to be peeled off from the end portions 12 b and 12 c, the base material 12 is broken from the cut 18 and the conductor layer 16 forming portion When the base material 12 breaks, the conductor layer 16 also breaks. Then, when the conductor layer 16 is broken, the buzzer BUZ of the anti-theft tag 70 issues an alarm.

Also, when the anti-theft tag 70 is lifted and the security label 10 is to be peeled off from the middle portion 12 a side of the base material 12, the base material 12 is interrupted by intermittent cuts 36 a and 36 b. The conductor layer 16 also breaks. When the conductor layer 16 is broken, the buzzer BUZ of the anti-theft tag 70 issues an alarm. In addition, since the cutout 36a curved outward is formed at the outermost part in the width direction of the base material 12, it is arranged at the outermost part of the base material 12 when the anti-theft tag 70 is lifted. The base material 12 is fractured starting from the cut 36a.

Further, a conductive liquid such as salt water may be applied to the label 10 to short-circuit the pads 14a and 14b. When the conductive liquid is short-circuited between the conductor layer 16 and the electrode layer 40, the normally open contact NO of the circuit shown in FIG. 15 is short-circuited, and an alarm is issued by the buzzer BUZ. Therefore, the pads 14a and 14b are short-circuited by conductive liquid, etc., so that no alarm is issued. It is not possible to peel off the label 10 in this manner.

As described above, if the security label 10 is illegally peeled off from the article 100, the conductor layer 16 is easily broken, or the pads 14a, 14b and the electrode layer 40 are short-circuited. An alarm is issued. Also, when the security label 10 is attached to the article 100, the terminal electrodes 54a, 54b of the anti-theft tag 70 and the pads 14a, 14b of the security label 10 are hidden. However, it is difficult to short-circuit the conductor layer 16 using a wire or the like near the terminal electrodes 54a and 54b. Therefore, it is difficult to remove the anti-theft tag 70 from the article 100 while the conductor layer 16 is short-circuited.

In addition, an adhesive tape or the like is stuck on the end portions 12b and 12c of the base material 12 to prevent the base material 12 from being reinforced so as not to break from the cut 20. As shown in FIG. 18, silicon or the like is printed on the end portions 12 b and 12 c of the base material 12 and the conductor layer 16 formed thereon, and A release layer 32 having low adhesion may be formed. The release layer 32 may be formed not only on the end portions 12b and 12c but also on the intermediate portion 12a. In this case, the pads 14a and 14b and the electrode layer 4 0 is formed so as to expose at least a connection portion with the terminal electrode.

Further, as shown in FIG. 19, a concealing layer 34 is formed to conceal the conductor layer 16 and the electrode layer 40 formed on the end portions 12 b and 12 c of the base material 12. May be. In this case, the concealing layer 34 is formed on the end portions 12 b and 12 c of the base material 12 and the conductor layer 16 and the electrode layer 40 formed thereon. Then, the release layer 32 is formed on the concealing layer 34. By forming such a concealing layer 34, the conductor layer 16 and the electrode layer 40 can be hidden from the surface of the security label 10 attached to the article 100, and the security label 1 The structure of the conductor layer 16 and electrode layer 40 is known from the surface of Can be prevented. Such a concealing layer 34 and a release layer 32 may be formed not only at the ends 12 b and 12 c of the base material 12 but also at the intermediate portion 12 a. The pads 14 a, 14 b and the electrode layer 40 are formed so that at least the connection portions with the terminal electrodes are exposed.

Further, it is not necessary to form the adhesive layer 26 on the entire surface of the other side of the substrate 12, and as shown in FIG. 20, the adhesive layer 26 is formed only on the ends 12 b and 12 c of the substrate 12.

26 may be formed. In this case, the release paper 28 may not be formed in the intermediate portion 12a. Of course, a continuous release paper 28 may be temporarily attached from one end 12b to the other end 12c. At this time, since the adhesive layer 26 is not formed on the intermediate portion 12a, all of the release paper 28 may be peeled at the time of use, and a cut 30 is formed in the release paper 28. It is not necessary.

Further, as shown in FIG. 21, the end of the electrode layer 40 is extended in the longitudinal direction of the base material 12, and is continuously formed inside the conductor layer 16 circulating at the ends 12 b and 12 c. Alternatively, it may be formed. If the electrode layer 40 having such a shape is adopted, the pads 14a, 14b and the substantially entire conductive layer 16 are close to the electrode layer 40, and even if a small amount of conductive liquid is used, the pad 14 A short circuit is caused between a, 14b and the electrode layer 40 or between the conductor layer 16 and the electrode layer 40, and the normally open contact NO is short-circuited, and an alarm is issued. In this case, the portions where the cuts 36 a and 36 b of the electrode layer 40 are formed are formed wide, and it is necessary to prevent the electrode layer 40 from being divided by the cuts 36 a and 36 b. . Also a break

Insert wires or the like into 36a and 36b, and short-circuit between pad 14a or 14b and electrode layer 40, or between conductor layer 16 and electrode layer 40. Also, the normally open contact NO is short-circuited and an alarm is issued.

In addition, as shown in FIG. 22, the pad 14a, 14b forming part and Linear intermittent cuts 20 and 22 may be formed between the orbital portion of the body layer 16. The cut 20 is formed along the width direction of the intermediate portion 12a on the end portions 12b and 12c sides of the intermediate portion 12a, similarly to the security label shown in FIG. Further, intermittent cuts 22 are formed on the intermediate portion 12a side of the ends 12b and 12c. The cut 22 is formed substantially parallel to the cut 20.

In the security label 10 having such cuts 20 and 22, when the anti-theft tag 70 attached to the article 100 is lifted and the security label 10 is to be peeled off, the cuts 20 and 22 are formed. As a result, the base material 12 breaks, and the conductor layer 16 also breaks. As a result, the buzzer of the anti-theft tag 70 — BU Z will sound an alarm.

If the anti-theft tag 50 or the anti-theft tag 70 is attached to the article 100 using the security label 10 as described above, the anti-theft tag can be attached to the article 100 with the conductor layer 16 continuous. It is difficult to remove 50 or anti-theft tag 70. For this reason, it is difficult to take the article 100 out of the store illegally. Furthermore, since the anti-theft tag 50 and the anti-theft tag 70 can be attached to the article 100 by sticking the security label 10 on it, it can be easily applied to the article 100 having a flat surface without handles. Can be attached to.

When an article is purchased by a customer and the anti-theft tag 50 or the anti-theft tag 70 is to be removed, for example, by inserting a key into the keyhole formed on the anti-theft tag 50 or the anti-theft tag 70 However, even if the reset switch RS of the circuit shown in FIGS. 15 and 23 is turned on and the conductor layer 16 of the security label 10 is disconnected, no alarm is issued. Therefore, by turning on the reset switch RS, the security label 10 can be removed from the article 100 in a state where no alarm is issued. The shape of the conductor layer 16 is not limited to the shape shown in each of the security labels described above, but may be any shape that connects the two pads 14a and 14b. However, since the conductor layer 16 needs to be disconnected when the base material 12 is broken, it is formed on the bonded portion of the base material 12, that is, on the end portions 12b and 12c. There is a need. Thus, as long as the conductor layer 16 is formed on the end portions 12 b and 12 c of the base material 12, the shape may be a zigzag shape or the like.

In the security label shown in FIG. 1, two intermittent cuts 20 and 22 are formed between the pads 14 a and 14 b and the conductor layer 16, respectively. However, it is sufficient that at least one of these cuts 20 and 22 is formed. Of course, three or more cuts may be formed between the pads 14a and 14b forming portion and the circling portion of the conductor layer 16.

Similarly, the security label having the curved cuts 36a and 36b is also formed between the pads 14a and 14b forming portion and the orbiting portion of the conductor layer 16. The number can be changed arbitrarily. If the cuts 20 and 22 and the cuts 36 a and 36 b are formed between the formation portions of the pads 14 a and 14 b and the orbital portion of the conductor layer 16, It may be formed at the middle part 12a of the part 12, or may be formed at the ends 12b and 12c. Further, in the security label on which the electrode layer 40 is formed, the shape of the electrode layer 40 can be arbitrarily changed, and is formed at an interval from the pads 14 a and 14 b and the conductor layer 16. It is sufficient that the normally open contact NO is formed in

The cut 18 may be formed in a curved shape or a broken line as long as it is formed so as to extend inward from the end of the base material 12. In addition, pads 14a and 14b The linear cuts 20 and 22 and the curved cuts 36a and 36b formed between the circumferential portion of the layer 16 and the curved cuts 36a and 36b are formed as a whole in a straight line. Can be formed into a curved shape or another shape as a whole. The intermediate portion 12a and the end portions 12b and 12c of the base material 12 are formed in a substantially rectangular shape. However, these shapes may be rounded or other shapes. It is not limited to a certain shape.
