Description

  The present invention relates to an IC tag label that reads and writes data using electromagnetic waves.

  Conventionally, an IC tag label attached to a book is known as an IC tag label for reading and writing data using electromagnetic waves (see, for example, Patent Documents 1 and 2).

  Such an IC tag label includes an IC tag having an antenna and an IC chip provided on the antenna, and a label base material that supports the IC tag, and an external reader / writer is provided on the IC tag. By irradiating electromagnetic waves from the antenna, current is generated in the antenna and the IC chip is driven.

  IC tag labels use various frequencies such as long waves of several hundred kilohertz, short waves of several tens of megahertz, UHF waves of several hundred megahertz, and microwaves of several gigahertz, and differ slightly depending on the country. Depending on the frequency, the characteristics of communication distance, directivity, communication speed, noise, and radio interference differ, and it is necessary to select according to the purpose of use and the surrounding environment. In particular, the UHF band is suitable for book inventory work because the communication distance is as long as several meters, but an electric field failure is likely to occur due to the presence of metal or liquid.

  Some books use a metal material as a design on the cover, or a metal-containing medium such as a CD or DVD is sandwiched between pages. When an IC tag label is attached to a book containing such a metal, the IC tag cannot be read due to the influence of the metal. In addition, when a book including such a metal is stacked on a book not including the metal, an IC tag attached to the book not including the metal may not be read.

  In order to solve such a problem, a method in which the IC tag label is configured to have a three-dimensional shape so as to increase the distance between the object to be attached and the IC tag of the IC tag label. However, in this method, since a three-dimensional shape is formed, the manufacturing cost is increased.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Note that, in the drawings attached to the present specification, for the sake of easy understanding of the drawings, the scale and the vertical / horizontal dimension ratio are appropriately changed and exaggerated from those of the actual ones.

  FIG. 1 is a plan view showing an IC tag label according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the IC tag label of FIG.

  As shown in FIGS. 1 and 2, the IC tag label 1 according to the present embodiment includes an IC tag 10 and a label base material 20 that supports the IC tag 10.

  Among these, the IC tag 10 includes an inlet film 11, an antenna 12 provided on the inlet film, and an IC chip 13 provided on the antenna 12. As the inlet film 11, for example, a synthetic resin film such as polyethylene terephthalate (PET) can be used. As the antenna 12, for example, a metal antenna such as aluminum can be used.

  As shown in FIG. 1, the antenna 12 has an IC chip 13 mounted thereon, a power feeding area 12a that feeds power to the IC chip 13, a radiation area 12b that receives and transmits electromagnetic waves, a power feeding area 12a, and a radiation area 12b. And a transmission region 12c connected to each other.

  The IC chip 13 is electrically connected to the antenna 12. The IC chip 13 has a built-in memory, and this memory usually includes a system area that cannot be rewritten and a user data area that can be rewritten (some of which have no rewritable area). In the memory of the IC chip 13, a unique code or the like is written for each chip so that each chip can be identified. As a result, when the IC tag 10 including the IC chip 13 is attached to a book, even a book with the same title can be distinguished by the code of the IC tag 10.

  When an electromagnetic wave from an external reader / writer hits the antenna 12, a current is generated in the antenna 12, and the IC chip 13 is driven using this current. The IC chip 13 receives data sent from the reader / writer and transmits information stored in its own memory wirelessly. In the IC tag 10 of the present embodiment, for example, UHF band electromagnetic waves are used when data is received and transmitted.

  As shown in FIG. 2, such an IC tag 10 is bonded to the label substrate 20 via an adhesive layer 26, and a protective film is provided on the IC chip 13 side of the IC tag 10 via an adhesive layer 16. 15 is bonded. As the protective film 15, a film made of synthetic resin such as polyethylene terephthalate (PET) or polypropylene (PP), paper, or the like can be used. In addition, as the adhesive layers 16 and 26, an adhesive of the same material can be used, and for example, a rubber-based resin adhesive, an acrylic resin adhesive, or a water paste-based adhesive can be used. The characteristics of the adhesive layers 16 and 26 can be selected from strong tackiness, weak tackiness and removability.

  Note that the inlet film 11 of the IC tag 10 is not necessarily essential and may be omitted. In this case, the antenna 12 may be formed directly on the label base material 20 without using the adhesive layer 26.

  As shown in FIGS. 1 and 2, the label substrate 20 has an elongated shape. As the label substrate 20, for example, a film made of synthetic resin such as polyethylene terephthalate (PET) or polypropylene (PP), paper, or the like can be used.

  The label base 20 is provided adjacent to the attachment portion 21 that can be attached to the book and the attachment portion 21, and the protruding portion that protrudes outward of the book in a state where the attachment portion 21 is attached to the book. 23.

  More specifically, the attachment portion 21 has a pair of insertion pieces 21a and 21b that can be inserted into the book with a part of the book sandwiched therebetween.

  In the illustrated example, the protruding portion 23 is provided so as to extend further to the right side from the central portion in the width direction in the right end portion of one insertion piece 21a, and the other insertion piece 21b is provided as one insertion piece. 21a is provided so as to extend further rightward from the widthwise outer portion outside the widthwise central portion of the rightward end portion of 21a, and via a fold line 22 provided at the widthwise outer portion of the right end portion. It can be folded so as to face the insertion piece 21a.

  An example of a manufacturing method of the label base material 20 having such a configuration will be described. First, a cut line 30 having a “U” shape or a “U” shape so as to surround at least a part of the radiation region 12 b of the antenna 12. Is formed on the label substrate 20, and then a fold line 22 is drawn from the start point and end point of the cut line 30 outward in the width direction. Thereby, the protrusion 23 is defined inside the cut line 30, and a pair of insertion pieces 21 a and 21 b that can be folded via the fold line 22 are defined outside the cut line 30. By such a production method, the label base material 20 having the pair of insertion pieces 21a and 21b and the protruding portion 23 can be produced very easily. In this production method, a cutout 24 corresponding to the protrusion 23 is formed in one insertion piece 21b.

  In the present embodiment, as shown in FIG. 1, at least a part of the radiation region 12 b of the antenna 12 is provided on the protruding portion 23 of the label base material 20. In the illustrated example, more than half of the radiation region 12 b is provided in the protrusion 23. The larger the portion provided in the projecting portion 23 in the radiation region 12b, the longer the communication distance, which is preferable.

  Moreover, in this Embodiment, as shown in FIG. 1 and FIG. 2, the display part 19 which displays the information regarding a book is provided in at least one 21b of a pair of insertion piece 21a, 21b of the label base material 20. FIG. Yes. Specifically, the display part 19 is formed by printing on the label base material 20, for example. Here, the information displayed on the display unit 19, that is, the information printed on the label base material 20, may include one or more of a book name, an author name, an issuing place, a price, and an ISBN. The information displayed on the display unit 19, that is, the information printed on the label substrate 20, is unique to each chip stored in the memory of the IC chip 13 or uniquely related to the unique information. It may be a letter / number or an optically recognizable code. In the illustrated example, the display unit 19 is provided only on one insertion piece 21b, but may be provided on both insertion pieces 21a and 21b. Thus, by providing the display part 19 in the label base material 20, it becomes possible to use the IC tag label 1 as a slip for ordering books, for example.

  The thickness of the entire IC tag label 1 is, for example, 0.1 mm to 0.5 mm. In the drawings, the thickness of each layer is exaggerated for easy understanding.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, as shown in FIG. 3, the pair of insertion pieces 21 a and 21 b of the label base material 20 is folded in two via the fold line 22 while leaving the protruding portion 23 as it is. At this time, the pair of insertion pieces 21a and 21b are preferably folded in a direction in which the display unit 19 is exposed to the outside.

  Next, as illustrated in FIG. 4, the pair of insertion pieces 21 a and 21 b are inserted into the book 2 from the upper end surface in a state where a part of the book 2 is sandwiched between the pair of insertion pieces 21 a and 21 b. Is done. In this case, even if the label base material 20 falls due to gravity, the upper end surface of a part of the book 2 sandwiched between the pair of insertion pieces 21 a and 21 b comes into contact with the fold line 22 of the label base material 20. Thus, further dropping of the label substrate 20 is prevented. Thereby, the entire label base material 20 is prevented from entering the inside of the book 2, and the protruding portion 23 is maintained in a state of protruding outward from the book 2.

  By the way, some books 2 use a metal material as a design on the cover, or a metal-containing medium such as a CD or DVD is sandwiched between pages. When the entire IC tag label is attached so as to be hidden in a book containing such metal, electromagnetic waves in the UHF band are reflected on the metal surface, so that data can be read from and written to the IC tag of the IC tag label with high accuracy. I can't.

  On the other hand, in this embodiment, since at least a part of the radiation region 12b of the antenna 12 is provided on the protruding portion 23 of the label base material 20, the radiation region of the antenna 12 is attached when the IC tag label 1 is attached to the book 2. At least a part of 12 b is exposed outside the book 2. Thereby, even if the book 2 contains a metal, the radiation region 12b of the antenna 12 can receive or transmit electromagnetic waves with the external reader / writer 3. For this reason, the IC chip 13 of the IC tag 10 can be operated accurately, and the reading and writing of data by the IC chip 13 can be surely executed.

  The present inventor prepares a book that is entirely covered with aluminum foil, and reads the IC tag 10 of the IC tag label 1 using the reader / writer 3 with the IC tag label 1 inserted from the upper end surface of the book. As a result, when the entire radiation area 12b of the antenna 12 is exposed outside the book 2, the information on the IC tag 10 can be read from a position 5 cm away from the spine of the book 2. Further, when half of the radiation area 12b of the antenna 12 is exposed outside the book 2, the information on the IC tag 10 can be read from a position 15 mm away from the spine of the book 2.

  As described above, according to the present embodiment, the label base material 20 is provided adjacent to the attachment portion 21 that can be attached to the book 2 and the attachment portion 21, and the attachment portion 21 is attached to the book 2. The projection 2 is projected outward from the book 2 in a state where the book 2 is placed, and at least a part of the radiation region 12b of the antenna 12 is provided in the projection 23, so that the structure is simple. Even when it is attached to a book 2 containing metal, data can be read and written to the IC tag 10 of the IC tag label 1 with high accuracy.

  In addition, according to the present embodiment, the pair of insertion pieces 21a and 21b of the attachment portion 21 are inserted into the book 2 with a part of the book 2 sandwiched therebetween, whereby an IC for the book 2 is obtained. Since the tag label 1 is attached, the IC tag label 1 can be easily removed from the book 2 by grasping the protrusion 23 and pulling it out in the direction opposite to the insertion direction. Therefore, the IC tag label 1 that can be easily attached to and detached from the book 2 can be obtained.

  In addition, according to the present embodiment, since at least one of the pair of insertion pieces 21a and 21b is provided with the display unit 19 for displaying information about the book, the IC tag label 1 is used as a slip for ordering books. You can also A slip for ordering a book is usually collected by a seller at the time of selling the book and is not taken out by the purchaser. Therefore, the IC tag label 1 can be reused, and an increase in cost can be suppressed.

  Various modifications can be made to the above-described embodiment. Hereinafter, an example of modification will be described with reference to the drawings.
