Description

The present invention relates to extraction election ticket with IC tags that have a IC chip removal structure. Specifically, due to the removal of the non-contact IC tag or al I C chip portion is temporarily effective use played a given purpose, that to utilize a portion was removed by the stripping have a lottery function Is also intended. Therefore, the application field of the present invention relates to the field of manufacturing and using non-contact IC tags.

Non-contact IC tags have been widely used for various purposes such as merchandise management because they can record and hold information and can exchange information by communicating with external devices in a non-contact manner. In particular, in recent years, in addition to the conventional proximity type non-contact IC tag (13.56 MHz), a non-contact IC tag for UHF band and microwave band capable of further long-distance communication has come to be used. .
However, since the information stored in the non-contact IC tag is recorded in the memory of the IC chip, even after the IC tag has fulfilled the purpose of use, the third party can keep the information as long as it is attached to the article. Cannot be effectively prevented from being read. In particular, non-contact reading is performed without the user's knowledge, so it is impossible to know the process, and it is possible that the leaked information will be misused and damaged. If such a state is left unattended, it becomes a social problem from the viewpoint of personal information protection and privacy infringement.

  Therefore, when sales of products with non-contact IC tags are completed and the purpose is fulfilled, the non-contact IC tags are removed from the products, or the functions of the non-contact IC tags are destroyed. And various countermeasures have been proposed. However, since the UHF band and the microwave band have an antenna structure different from that of the conventional 13.56 MHz band, there is a problem that the conventional IC tag method cannot be adopted as it is.

As prior art of the structure that destroys the function of the non-contact IC tag, there are Patent Document 1, Patent Document 2, Patent Document 3, and the like. In Patent Document 1, the IC tag itself has a structure that is easily collapsed, but is different from the cut-off structure as in the present application. Patent Document 2 differs from the present application in the layer configuration and cut-out structure of the wireless IC tag. Patent Document 3 is applied to an IC tag having a planar coiled antenna. However, in the case of a dipole antenna as in the present application, the IC tag cannot be invalidated only by deleting a part of the antenna. .
Moreover, although the prior art which utilized a non-contact IC tag for a lottery ticket is not detected especially, there exists patent document 4 as a kite and a tow | drawing lottery system using a non-contact IC tag.

  In a UHF band or microwave band IC tag having a dipole antenna that has recently been used, a means for invalidating an IC tag is provided for the purpose of preventing wiretapping of information after the IC tag is used. Is. In addition, when invalidating the IC tag, the purpose of the lottery ticket is also provided.

The gist of the present invention that solves the above problems is that a dipole antenna is formed on a base film, an IC chip is mounted on the antenna, the antenna surface is covered with a surface protective sheet, and the adhesive layer is peeled off from the back surface of the base film. In a non-contact IC tag having paper, the IC chip and the left and right dipole antennas are displayed in order to display the lottery result at the same time as invalidating the IC tag after the non-contact IC tag is attached to the article and the intended use is finished. The base film is formed from one end to the other end so that two perforation lines for removing a region including a part from the surface of the article are orthogonal to or oblique to the length direction of the dipole antenna. A release layer and a colored layer are formed on the surface in contact with the adhesive layer in the region, and the colored layer is transferred according to the shape of the release layer to display characters. Lottery ticket with IC tag, is in.

The second aspect of the present invention that solves the above problem is that a dipole antenna is formed on a base film, the antenna surface having an IC chip attached to the antenna is covered with a surface protection sheet, and the back surface of the base film is also interposed through an adhesive layer. In order to display the lottery result at the same time as invalidating the IC tag after attaching the non-contact IC tag to the article and finishing the intended use, The base film is formed from one end of the base film to the other end so that two perforations for removing a region including a part of the left and right dipole antennas are orthogonal to or oblique to the length direction of the dipole antenna. A release layer and a colored layer are formed on the surface of the removal area where the adhesive layer is in contact with the protective sheet, and the colored layer is transferred depending on the shape of the release layer. Lottery ticket with IC tag which is characterized in that is is in.

Lottery with IC tag of the present invention, since the IC chip of the IC tag is to be removed by two perforation lines, the eavesdropping can be similarly disable IC tag can be prevented. In addition, since the lottery result is displayed in the portion where the IC chip is removed, the non-contact IC tag can be used as a function combined with the lottery ticket.

The present invention will be described below with reference to the drawings.
1 is a schematic plan view showing an example of an IC tag having an IC chip removal structure, FIG. 2 is a cross-sectional view of an IC tag having an adhesive layer, and FIG. 3 is a cross-sectional view of an IC tag having a back surface protection sheet, 4 is a diagram showing a first embodiment of an IC tag with a lottery ticket, FIG. 5 is a diagram showing the second embodiment, and FIG. 6 is a diagram showing the third embodiment.

FIG. 1 is a schematic plan view showing an example of an IC tag having an IC chip removal structure.
In the case of FIG. 1, the half-wave dipole antenna 2 is formed on the surface of the base film 11, and the IC chip 3 is mounted between the left and right antennas 2L and 2R (feeding portion). Since the recent IC chip 3 is miniaturized (one side has a square shape of about 0.2 mm to 2.0 mm), it does not actually appear as large as FIG. The antenna shape is a folded shape, but is not limited to this shape. Moreover, a 1 wavelength loop antenna may be sufficient.
Normally, one unit of the UHF band non-contact IC tag 1 is manufactured to a size (base material size) of about 10 cm in length and about 25 mm to 40 mm in width. Since the length of the antenna is related to the wavelength of the radio wave, in the case of the microwave band, the antenna has a shorter shape.

The IC tag 1 having the IC chip removal structure is characterized in that, as shown in FIG. 1, the IC chip 3 and the region including the left and right antennas 2L and 2R close to the IC chip 3 can be removed. That is, two perforation lines 4l and 4r are formed. The perforation lines 4l and 4r may lead from one end of the long side of the base film 11 to the other opposite end as shown in FIG. 1 (A), and the IC chip 3 is connected as shown in FIG. 1 (B). You may make it complete | finish in the middle of the exceeded part. Further, as shown in FIG. 1C, a perforation line 4t perpendicular to the perforation lines 4l and 4r or a semicircular perforation line (not shown) may be inserted in a portion beyond the IC chip 3. In the former case, the letter “U” is formed as a whole, and in the latter case, the letter “U”. A region surrounded by the perforation line is a removal region 10. The removal area 10 includes a part of the antennas 2L and 2R. Only the IC chip 3 may be removed. However, if it is miniaturized as described above, it is difficult to remove only the IC chip 3 portion. In the case of FIG. 1, the perforations 4 l and 4 r are orthogonal to the length direction of the dipole antenna 2, but may be skewed. Although the removal area 10 is formed in a band shape, the removal area 10 is not limited to a band shape or a rectangular shape, but may be formed in a substantially triangular shape by two perforation lines that are inclined at different angles.

  As shown in FIG. 1B, if the perforation lines 4l and 4r are terminated in the middle of the portion beyond the IC chip 3, the removal area 10 is not separated from the main body of the IC tag 1, so that the IC chip 3 Can be prevented from being scattered or scattered around. On the other hand, in the case of FIG. 1A or FIG. 1C, it is easy to collect the removed portion. These may be appropriately changed according to the purpose of use. Although the lottery ticket-attached IC tag is not shown, the perforation lines 4l and 4r can be inserted in the same manner.

  FIG. 2 is a cross-sectional view of an IC tag having an adhesive layer. This corresponds to a cross section taken along line AA in FIG. The non-contact IC tag 1 has a surface protective sheet 5 made of a plastic film or a paper substrate on the surface, an adhesive layer 7 and a release paper 12 on the back surface, and is attached to an article with the adhesive layer 7 for use. In the form to be used (first form), and the form in which the adhesive layer is not used and the back surface as well as the back surface is covered with a back protective sheet 8 made of a plastic film or a paper base, and used mainly as a hanging tag or a display tag. There is a thing (second form). 2 is the former, and FIG. 3 described later is the latter.

  Also in the case of the form used by sticking to an article, as shown in FIG. 2 (A), when the perforation lines 4l and 4r are inserted from the surface protective sheet 5 to the pressure-sensitive adhesive layer 7, FIG. As described above, the perforation lines 4l and 4r may be provided up to the surface of the base film 11 in contact with the pressure-sensitive adhesive layer 7. In the latter case, it is preferable to form a release layer 9 on the surface of the base film 11 that contacts the pressure-sensitive adhesive layer 7. This is because the removal zone 10 is easily removed from the pressure-sensitive adhesive layer 7. Although the release paper 12 is attached to the lower surface of the pressure-sensitive adhesive layer 7, since it is used after being removed, it is not necessary to put a perforation line up to the release paper 12. In FIG. 2, the adhesive layer 6a and the antenna surface are shown apart from each other, but they are actually in close contact with each other. The same applies to each figure after FIG.

FIG. 3 is a cross-sectional view of an IC tag having the back protective sheet 8. In this case, since the non-contact IC tag 1 is normally used without being attached to an article, if the removal area 10 is removed by the perforation lines 4l and 4r, the removal area 10 and the left and right pieces are separated. become.
FIG. 3A shows an example in which the perforation lines 4 l and 4 r are penetrated to the back protective sheet 8. In this embodiment, when the perforation lines 4l and 4r are inserted so as to lead from one end of the long side of the base film 11 to the other end as shown in FIG. Will be separated. However, the purpose of reading prevention can be achieved.
In the form of FIG. 3 (A), since it is not possible to display characters in the removal area 10 so as not to be visible from the beginning, it is considered unsuitable for use as an IC tag with a lottery ticket.

  FIG. 3B shows an example in which the perforated lines 4 l and 4 r are not penetrated to the back protective sheet 8 and are cut to the surface where the adhesive layer 6 b contacts the back protective sheet 8. In this embodiment, the release layer 9 is formed in at least the removal area 10 portion of the back protective sheet 8 in contact with the adhesive layer 6b, and the removal area 10 can be easily peeled from the portion. Therefore, even when the perforation lines 4l and 4r are inserted so as to lead from one end of the base film 11 to the other end as shown in FIG. 1A, the back protection sheet 8 remains, so the IC tag 1 is left and right. Will not be separated. As will be described later, this form can also be used for IC tags with lottery tickets.

Next, a description will be given of extracting election ticket with IC tag.
FIG. 4 is a diagram showing a reference embodiment of an IC tag with a lottery ticket. 4A is a cross-sectional state, and the inside of the circle in FIG. 4B is a state in which the removing unit 10 is peeled off and the character display unit 17 is enlarged. In the reference embodiment, in the IC tag 1 of the first form configured as shown in FIG. 2A, the concealment print 15a and character printing such as “hit” are formed on the side of the adhesive layer 7 of the base film 11 in the removal area 10. A printing unit 15 consisting of 15b can be provided. Or the method of affixing the label (not shown) of the small piece by which the said character printing was carried out to the base sheet 11 may be used. As a matter of course, the display content of the character print is not visible from the surface protection sheet 5 side of the IC tag 1 with a lottery ticket.

  When the removal area 10 is peeled off, the lottery result character display portion 17 can be seen as shown in FIG. The adhesive layer 7 may remain attached to the surface of the base film 11 of the IC tag. In this embodiment, when the IC tag is attached to the article, if the release paper 12 is peeled off, the character display 16 is visually recognized through the pressure-sensitive adhesive layer 7. Therefore, the character display unit 17 becomes invisible after being attached to the article, and is effective as an IC tag with a lottery ticket.

FIG. 5 is a diagram showing a first embodiment of an IC tag with a lottery ticket.
In the second embodiment, in the configuration of the IC tag of the first form in FIG. 2B, the release layer 9 on the side of the adhesive layer 7 of the base film 11 in the removal area 10 is printed in a character pattern. And concealment printing 16 is further performed on the lower surface of the release layer 9 (adhesive layer 7 side).
When the IC tag with a lottery ticket is peeled from the article, the character pattern portion of the release layer 9 remains on the adhesive layer 7 side, and the portion that is not the character pattern remains on the removal area 10 side. Therefore, if the character pattern of the release layer 9 is a blank character, a character such as “hit” remains on the removal area 10 side, and if it is a bag character, the opposite phenomenon occurs. FIG. 5B shows an example in which the character pattern portion of the release layer 9 is missing and a “hit” character appears on the removal area 10 side. In the first embodiment, since there is the concealment printing 16, the character shape cannot be visually recognized even if the release paper 12 is peeled off.

FIG. 6 is a diagram showing a second embodiment of the IC tag with a lottery ticket.
In the second embodiment, the IC tag of the second embodiment of the structure of FIG. 3 (B), the a removal zone 10 for printing the release layer 9 of adhesive layer 7 side of the base film 11 into a character pattern. And concealment printing 16 is further performed on the lower surface of the release layer 9 (adhesive layer 7 side).
As in the case of FIG. 5, when the IC tag with a lottery ticket is peeled from the article, the character pattern portion of the release layer 9 remains on the adhesive layer 7 side, and the non-character pattern portion remains on the removal area 10 side. It will be. FIG. 6B shows an example in which the extracted character pattern portion of the release layer 9 appears as a “hit” character shape on the removal area 10 side. Also in the case of the second embodiment, the character shape cannot be visually recognized because of the concealment printing 16 and the back surface protection sheet 8.
