Description

  The present invention relates to a label with a two-dimensional code that can prevent duplication by an inexpensive method.

  Traditionally, at pachinko parlors, players can exchange pachinko balls and medals earned by players for special prizes, and take these special prizes to the prize exchange office. ing. Since this special prize has a monetary value that can be exchanged for cash, it is particularly likely to be counterfeited. Therefore, in general, pachinko parlors are managed by attaching an RFID label to the prize body, and reading the information recorded on the IC chip of the RFID label with a reader / writer to determine whether the prize is genuine or not. (See, for example, Patent Document 1 below).

JP 2000-126439 A

  As described above, conventionally, an RFID system including an RFID label and a reader / writer is used to manage prizes. However, each RFID label contains electronic components such as an IC chip, so that each one is expensive, and all pachinko parlors and gift exchanges require equipment such as reader / writers. For this reason, there has been a problem that it takes a great deal of cost to operate the system.

  Therefore, the present invention has been made to solve such a problem, and the object of the present invention is to be able to be used inexpensively as a medium replacing an RFID label and to prevent counterfeiting due to duplication. It is to provide a label with a two-dimensional code.

  In order to achieve the above object, a label with a two-dimensional code according to the present invention is configured such that a two-dimensional code is provided on a part of the label, and the two-dimensional code is destroyed when the label is peeled off after application. It is characterized by.

  Here, as a configuration in which the two-dimensional code is destroyed when the label is peeled off, a configuration in which the two-dimensional code is printed on a cut line formed on the label can be employed. In this case, in order to ensure that the two-dimensional code does not function when peeled off, it is preferable that the cut line is formed at a position where the fixed pattern and the data cell are separated from the symbols of the two-dimensional code.

  As another configuration in which the two-dimensional code is destroyed when the label is peeled off, the label is a laminated label formed by pseudo-adhering a light transmissive upper layer label on the lower layer label, and is formed on the lower layer label. Alternatively, the two-dimensional code may be configured by superimposing a part of the two-dimensional code and the remaining part of the two-dimensional code formed on the upper layer label.

  Specifically, a part of the two-dimensional code formed on the lower layer label is a fixed pattern, and the remaining part of the two-dimensional code formed on the upper layer label is a data cell, or 2 formed on the lower layer label. A configuration in which a part of the dimension code is a data cell and the remaining part of the two-dimensional code formed on the upper layer label is a fixed pattern is conceivable. Alternatively, a part of the two-dimensional code formed on the lower layer label is the outer peripheral frame of the quiet zone, and the remaining part of the two-dimensional code formed on the upper layer label is a symbol, or the lower layer label A configuration in which a part of the formed two-dimensional code is a symbol and the remaining part of the two-dimensional code formed on the upper layer label is an outer peripheral frame of a quiet zone is conceivable.

  In the case of a laminated label, a part of the two-dimensional code formed on the lower layer label and the remaining part of the two-dimensional code formed on the upper layer label are composed of an infrared absorbing material, and at least one of the upper layer label and the lower layer label On the other hand, a concealing layer covering the two-dimensional code may be formed of an infrared non-absorbing material. In this case, the lower layer label is preferably made of a light reflective material.

  According to the label with a two-dimensional code according to the present invention, since various data can be recorded on the two-dimensional code provided on the label, it can be used in the same manner as a conventional RFID label, and the RFID label A cheaper medium can be provided. In addition, if the label once pasted is to be peeled off, the two-dimensional code is destroyed. For this reason, since there is a duplication prevention function different from that of a normal two-dimensional code, it is possible to prevent troubles caused by forgery. Further, since the trace peeled off from the label remains, it can be seen that the label has been tampered with and can be used as a seal seal having an opening detection function.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings attached to the application. As shown in the drawings, a label with a two-dimensional code according to the present invention is configured such that a two-dimensional code is provided on a part of the label, and the two-dimensional code is destroyed when the label is peeled off after application. It is characterized by this.

[First Embodiment]
1 to 4 show a first embodiment of the present invention. In FIG. 1, a label L1 with a two-dimensional code according to the present embodiment employs a QR code of model 1 (registered trademark, the same applies hereinafter) as an example of the two-dimensional code 1.

  Referring to FIG. 2, the two-dimensional code-added label L <b> 1 includes a label 11 and a release paper 12.

  The label 11 is obtained by applying an adhesive to the back surface of a label substrate 13 that can be printed by various printers, and providing an adhesive layer 14. As the label substrate 13, for example, paper such as high-quality paper, recycled paper, thermal paper, and thermal transfer coated paper, and resin films such as polyester film and polypropylene film can be used. Various adhesives such as rubber-based, acrylic-based, hot-melt-based, and silicone-based adhesives can be used as the adhesive for the adhesive layer 14, and among these, acrylic emulsion-based adhesives used particularly for paper tacks are used. Is preferred.

  On the other hand, the release paper 12 protects the adhesive surface of the label 11 until it is used, and a release layer 16 is provided by applying a silicone release agent to the surface of the paper material 15. The label 11 and the release paper 12 are bonded to each other through a boundary surface between the adhesive layer 14 and the release layer 16 so as to be peeled off.

  The QR code 1 is printed on the surface of the label base material 13 by a printer, and includes a symbol 2 and a quiet zone (margin) 3 around it. The symbol 2 is composed of a fixed pattern and a data area. As a fixed pattern, a finder pattern (cutout symbol) 4 for position detection is arranged at three corners, and a blank area separator 5 is interposed between the finder patterns 4 and 4. A timing pattern 6 for determining the center coordinates is arranged. Further, in the data area surrounded by the finder pattern 4, the separator 5, and the timing pattern 6, there is provided a data cell 7 obtained by binarizing the data composed of numbers, English characters, Kanji characters, Kana characters, etc. and converting the code. ing. On the other hand, the quiet zone 3 is provided with a blank area for four cells around the symbol 2 in order to increase the contrast when the QR code 1 is read.

  The label 11 is provided with a cut line 17 as a configuration for destroying the QR code 1. The cut line 17 refers to a line that is cut in advance so that the label 11 can be cut without using a cutting tool such as a cutter. In FIG. 1, as an example of the cut line 17, a perforation marked with “X” is provided on the diagonal line of the label 11. Further, the perforations are formed by performing a half-cut process for the thickness of the label 11 as shown in FIG. 2, that is, the depth reaching the release layer 16 from the surface of the label base 13.

  The label L1 with a two-dimensional code of the present embodiment is configured as described above, and when used, the release paper 12 is peeled off and attached to the adherend with the adhesive layer 14 on the back side of the label. Here, since various data can be recorded on the QR code 1 printed on the label 11, it can be used in the same manner as a conventional RFID label, and a medium that is cheaper than the RFID label is configured. Can do. Further, when the label 11 once attached is to be peeled off, the perforation of the cut line 17 is broken and the QR code 1 is broken. For this reason, since there is an anti-duplication function different from that of a normal QR code, it is possible to prevent troubles caused by forgery. Moreover, since the trace which peeled off on the label 11 remains, it turns out that it opened illegally and can also be utilized as a sealing sticker provided with the opening detection function.

  In the present embodiment, as a specific form of the cut line 17, the perforation marked with “X” is provided on the diagonal line of the label 11, but the form of the cut line 17 is not limited to this. For example, as shown in FIG. 3, the perforation 17a (refer to the figure (a)) which combined several circular arc curves, and the one spiral perforation 17b (refer to the figure (b)). Alternatively, a plurality of circular slits 17c (see FIG. 5C) may be employed. In these examples, since the cut line 17 is set along the direction in which the force acts when the label 11 is peeled off, the QR code 1 can be reliably broken at the time of opening.

  Further, when reading the data cell 7 of the QR code 1, the finder pattern 4 is an indispensable fixed pattern for position detection. For this reason, the cut line 17 is preferably formed at a position where the fixed pattern and the data cell 7 are separated. For example, the example shown in FIG. 4 is a cross-shaped perforation in which three finder patterns 4 are separated separately, and the end of the perforation is a trigger at the time of breaking so that it always reaches the perforation when peeling. A notch 18 is formed. According to these examples, since the finder pattern 4 is properly destroyed when the label 11 is peeled off, the QR code 1 after opening can be reliably read.

[Second Embodiment]
5 to 7 show a second embodiment of the present invention. In FIG. 5, the label L2 with a two-dimensional code of the present embodiment employs a laminated label formed by pseudo-bonding two layers of labels 21 and 22 as another configuration example for destroying the two-dimensional code 1. is there.

  Referring to FIG. 6, the laminated label includes a lower layer label 21 and an upper layer label 22, and a part of the two-dimensional code 1 formed on the lower layer label 21 and the remaining part of the two-dimensional code 1 formed on the upper layer label 22. Are superimposed to form a two-dimensional code 1.

  The lower layer label 21 is obtained by applying an adhesive to the back surface of a label base material 23 made of a light-reflective material such as paper that reflects or easily reflects light, and provides an adhesive layer 24. A release paper 27 is bonded to the adhesive layer 24, and the adhesive surface is protected until use. On the lower layer label 21, a fixed pattern (finder pattern 4 and timing pattern 6) is printed on the surface of the label substrate 23 with an infrared absorbing material. Here, the infrared absorbing material is a material having a characteristic of absorbing irradiated infrared light and can be recognized by a code reader, but is difficult to faithfully reproduce by copying with a copying machine. Examples of the infrared absorbing material include IR ink (infrared drying type ink), ink containing a carbon black pigment, ink added with an infrared absorbent as an auxiliary agent, and the like.

  The upper layer label 22 is printed with a portion other than the fixed pattern (data cell 7) with an infrared absorbing material on the surface of a label base material 25 made of a transparent or light transmissive material (eg, film or thin paper). Has been. Further, a pseudo adhesive layer 26 to which a pseudo adhesive made of natural rubber or synthetic rubber pressure sensitive adhesive is applied is provided on the back surface of the label substrate 25. The pseudo-adhesive layer 26 has a function of temporarily adhering the lower layer label 21 and the upper layer label 22 so that the lower layer label 21 and the upper layer label 22 can be peeled off before use. It has a function that makes it impossible to re-apply. Instead of the pseudo-adhesion layer 26, a pseudo-adhesion structure using an open type film (not shown) in which transparent films are thermocompression bonded may be employed.

  The label L2 with a two-dimensional code of the present embodiment has a fixed pattern printed on the lower layer label 21 and a data cell printed on the upper layer label 22 by pseudo-bonding the lower layer label 21 and the upper layer label 22 as shown in FIG. 7 is overlapped to form one two-dimensional code 1. Thereby, when reading the QR code 1, the infrared light emitted from the QR code reader is transmitted through the upper layer label 22 and absorbed by the fixed pattern of the lower layer label 21, and the exact position of the symbol 2 is detected. Further, since the data cell 7 of the upper layer label 22 also has infrared absorption characteristics, it is also clearly recognized by absorbing infrared light. Therefore, since the entire symbol 2 of the QR code 1 can be recognized, the data recorded in the data cell 7 can be read accurately.

  In addition, when the label L2 with the two-dimensional code is copied by a copying machine, the fixed pattern printed with the infrared absorbing material and the data cell 7 are copied with a low toner density, and the accurate shape of the symbol 2 is obtained. It is difficult to reproduce. For this reason, in the QR code 1 after copying, even if the toner has some infrared absorption characteristics, the shape of the symbol 2 is not clearly recognized, so that the data recorded in the data cell 7 cannot be read. Accordingly, since it is possible to easily determine that the copy has been made, forgery using a copy machine can be reliably prevented.

  Further, when an attempt is made to peel off the laminated label once pasted, the upper layer label 22 is separated from the lower layer label 21 and peeled off. Here, even if an attempt is made to reapply the peeled upper layer label 22, the pseudo adhesive layer 26 cannot be attached because the adhesive force is lost. In addition, when the back surface of the upper layer label 22 is applied with glue, the position of the finder pattern 4 of the lower layer label 21 and the data cell 7 of the upper layer label 22 is displaced, so that the QR code 1 cannot be read. An unauthorized opening can be detected.

  As described above, in the present embodiment, the laminated label formed by pseudo-bonding the lower layer label 21 and the upper layer label 22 is employed. However, in addition to this, the structure shown in FIG. 7 may be employed. For example, in the case shown in FIG. 7A, a concealing layer 31 is provided on the surface of the upper layer label 22 by covering and printing the QR code 1 with an infrared non-absorbing ink having no infrared absorption characteristics. Further, in FIG. 7B, the concealing layer 31 is provided not on the upper layer label 22 but on the lower layer label 21. Thus, by providing the concealment layer 31 on at least one of the upper layer label 22 and the lower layer label 21, it is not noticed that the QR code 1 is printed when viewed from the outside. In addition, when this laminated label is copied by a copying machine, the entire portion of the concealing layer 31 is copied black, so that it is possible to prevent duplication of the QR code 1 due to copying.

  Further, as shown in FIG. 7C, it is preferable to provide a concealing layer 31 on both the upper layer label 22 and the lower layer label 21. In this case, it is possible not only to prevent duplication of the QR code 1 by copying as described above, but also to prevent forgery by reattachment after opening. The reason for this is that even if the upper layer label 22 is peeled off and then reattached, the QR code 1 is completely hidden, so there is no mark for positioning, and the finder pattern 4 and the data cell 7 are This is because they cannot be accurately superimposed.

  In this embodiment, the finder pattern 4 is printed on the lower layer label 21 and the data cell 7 is printed on the upper layer label 22. On the contrary, the data cell 7 is printed on the lower layer label 21 and the upper layer label 22 is printed. Alternatively, the finder pattern 4 may be printed. However, since the finder pattern 4 is common to all codes and the data cell 7 is different for each code, from the viewpoint of printing variable data on the upper label 22 after pseudo adhesion, the data cell 7 is displayed on the upper label 22. The form of printing is preferable.

[Third Embodiment]
8 and 9 show a third embodiment of the present invention. In FIG. 8, the label L3 with a two-dimensional code of this embodiment is the same as that of the second embodiment in that a two-layer laminated label is adopted, but a part of the QR code 1 formed on the lower layer label 21 The combination with the remainder of the QR code 1 formed on the upper layer label 22 is different.

  As shown in FIG. 8, as a part of the QR code 1, an outer peripheral frame 32 that surrounds the quiet zone 3 is printed on the lower layer label 21 with an infrared absorbing material. On the other hand, on the upper layer label 22, the entire symbol 2 including the finder pattern 4, the timing pattern 6, and the data cell 7 is printed with an infrared absorbing material. Further, as shown in FIG. 9, a concealing layer 31 is provided with an infrared non-absorbing ink on both the lower layer label 21 and the upper layer label 22. The concealing layer 31 may be provided on at least one of the lower layer label 21 and the upper layer label 22.

  According to the label L3 with a two-dimensional code of this embodiment, duplication of the QR code 1 by copying can be prevented in advance for the same reason as that of the second embodiment. Also, if the symbol 2 printed on the upper layer label 22 is slightly displaced even if an attempt is made to apply it again after the upper layer label 22 has been peeled off, a red zone will appear in the area of the quiet zone 3 required around the symbol 2. The outer peripheral frame 32 printed with the outer absorbent material will enter. For this reason, when reading with a QR code reader, the contrast between the symbol 2 and the background is lowered, and the reading of the QR code 1 is hindered. Therefore, it is possible to prevent forgery due to re-sticking and detect that it has been tampered with.

  In the present embodiment, the outer peripheral frame 32 of the quiet zone 3 is printed on the lower layer label 21 and the symbol 2 is printed on the upper layer label 22. On the contrary, the symbol 2 is printed on the lower layer label 21 and the upper layer label 22 is printed. Alternatively, the outer peripheral frame 32 of the quiet zone 3 may be printed. However, from the viewpoint of printing the variable data on the upper layer label 22 after the pseudo adhesion, it is preferable to print the symbol 2 on the upper layer label 22. In the second and third embodiments, the label base material 23 of the lower layer label 21 is made of a light-reflective material. However, if the adherend to be attached is difficult to absorb light and easily reflects, the lower layer label 21 The label base material 23 of the label 21 may be made of a transparent material that easily transmits light (for example, a film or thin paper).

  As described above, the embodiments have been described. However, the present invention is not limited to the above-described embodiments, and many modifications can be made depending on the ordinary creative ability of those skilled in the art within the scope of the technical idea of the present invention. Is possible.
