Description

  The present invention relates to a book management system and a reserved shelf system using IC (Integrated Circuit) tags.

  In recent years, libraries have replaced IC cards with books instead of the conventional bar code method, book inspection with a contactless handy reader, book lending processing by users using an automatic lending machine, and books with a gate antenna. Technology to prevent unauthorized removal has been introduced. Such IC tag technology has gained widespread use because it has the advantage of saving labor for librarians and preventing book theft on the library side, speeding up the lending process on the user side, and concealing the rental materials. .

  In libraries that have become more IC-tagged, there is a reserved book corner in the building, the reserved books are placed on a reserved shelf with a reading antenna, and the book is lent out by the user himself. The return process and sorting are automated by passing a return machine (return sorter) equipped with a reading antenna at the time of return.

In addition, the dimensions of the members in each drawing are appropriately enlarged or reduced for easy understanding. Also, in the drawings, some of the members that are not important for describing the embodiment are omitted.

  FIG. 1 is a diagram for explaining a book management system 10 according to an embodiment of the present invention. The book management system 10 is installed in a library or the like, and is particularly suitable for placing a book covered with a cover having an electromagnetic wave shielding action such as aluminum vapor-deposited paper.

  The book management system 10 includes a book shelf 14 on which books 12 are placed, an IC tag 24 attached to the inside of the book 12, a conductive member 26 inserted inside the book 12, a sheet-like antenna 18, A reader / writer 20 and a management device 22 are provided.

  FIG. 1 shows only one level of the bookcase 14. The book shelf 14 includes a shelf board 16 and a back board 17. The material of the shelf board 16 and the back board 17 is not specifically limited, You may form from a metal, a synthetic resin, glass, wood, etc.

  In the present embodiment, the sheet-like antenna 18 is installed on the shelf plate 16 of the book shelf 14. Instead, the sheet-like antenna 18 may be installed on the back plate 17 or may be installed on both the shelf plate 16 and the back plate 17.

  FIG. 2 shows the book 12 placed on the book management system 10. As shown in FIG. 2, the book 12 has a cover 12 d that covers the front cover 12 a, the back cover 12 b, and the spine cover 12 c. In the present embodiment, the cover 12d is made of a material having an electromagnetic wave shielding action such as aluminum vapor deposition paper.

  An IC tag 24 is affixed to the turning portion 12 e inside the front cover 12 a of the book 12. Information (title, management number, etc.) of the book 12 to which the IC tag 24 is attached is written in the IC tag 24. The IC tag 24 has an elongated shape, is provided with an IC chip at a substantially central portion thereof, and is provided with antennas on both sides of the IC chip. The IC tag 24 is affixed in the vicinity of the throat portion 12f in the turn-back portion 12e so that the longitudinal direction is parallel to the throat portion 12f. In the present embodiment, the IC tag 24 is affixed to the facing part 12e, but may be affixed, for example, to the door part 12g, or may be affixed near the throat between pages. The reason why the IC tag 24 is affixed to the vicinity of the throat portion 12f near the spine 12c in this way is because the improvement of the recognition performance in the collection search by the handy reader in the state where the book 12 is placed on the book shelf 14 is considered. is there.

  Returning to FIG. 1, a reader / writer 20 is connected to the sheet-like antenna 18. The reader / writer 20 communicates with the IC tag 24 of the book 12 via the sheet-like antenna 18. The communication frequency between the sheet antenna 18 and the IC tag 24 may be, for example, the UHF band (900 MHz to 950 MHz).

  The reader / writer 20 is communicably connected to the management device 22. The management device 22 manages the book 12 based on the information of the IC tag 24 read through the sheet antenna 18 and the reader / writer 20. That is, the management device 22 manages whether or not the book 12 is placed on the book shelf 14. If the information of the IC tag 24 can be read, it can be detected that the book 12 with the IC tag 24 is placed on the bookshelf 14. On the contrary, if the information of the IC tag 24 cannot be read, it can be detected that the book 12 with the IC tag 24 is not placed on the bookshelf 14.

  When the book 12 is covered with a cover 12d having an electromagnetic wave blocking action as in the present embodiment, the sheet antenna 18 and the IC tag 24 cannot communicate with each other, and information on the IC tag 24 may not be read.

  Therefore, in the book management system 10 according to the present embodiment, the inside of the book 12 is arranged so that the information on the IC tag 24 can be read even if the book 12 is thus covered with the cover 12d having an electromagnetic wave shielding function. The conductive member 26 is inserted into the. The conductive member 26 may be, for example, a rectangular metal plate or a transparent dielectric film. In FIG. 2, a conductive member 26 is inserted between the turning portion 12 e of the book 12 and the door portion 12 g.

  When the conductive member 26 is inserted inside the book 12 as described above, the electromagnetic wave from the sheet-like antenna 18 travels through the conductive member 26 and is emitted from the edge thereof to reach the IC chip of the IC tag 24. Similarly, the electromagnetic wave from the IC tag 24 travels through the conductive member 26, is emitted from the edge thereof, and reaches the sheet-like antenna 18. In this way, even when the book 12 is covered with the cover 12d having an electromagnetic wave shielding function, communication is possible between the sheet antenna 18 and the IC tag 24, and information on the IC tag 24 is read. Can do.

  The conductive member 26 may be affixed to, for example, the facing portion 12e or the door portion 12g inside the book. In this case, a transparent conductive film is suitable as the conductive member 26.

  Alternatively, the conductive member 26 may be manually inserted inside the book 12 when the book 12 is placed on the bookshelf 14. In this case, a metal plate is suitable as the conductive member 26. After the conductive member 26 is inserted into the book 12, the book 12 may be bound with a rubber band or the like in order to prevent the conductive member 26 from coming out of the book 12.

  FIG. 3 shows a book management system 30 according to another embodiment of the present invention. In the book management system 30 shown in FIG. 3, a plurality of conductive members 26 are installed on the shelf board 16 at intervals. Each conductive member 26 has an L-shaped book end shape and is made of a metal material. Each conductive member 26 includes a first surface 25 and a second surface 27 that are perpendicular to each other, and the second surface 27 is disposed on the sheet-like antenna 18, so that the first surface 25 is located with respect to the sheet-like antenna 18. And standing upright. Each conductive member 26 may be configured only from the first surface 25.

  In the book management system 30 according to the present embodiment, the book 12 is placed on the book shelf 14 such that the first surface 25 of the conductive member 26 is inserted between the books 12. In the book management system 30, one conductive member 26 is prepared for one book 12. The interval between the conductive members 26 is appropriately set according to the thickness of the book 12 to be placed. A plurality of L-shaped conductive members 26 may be integrated.

  In the book management system 30, each conductive member 26 may be slidably installed along the longitudinal direction of the book shelf 14. In order to allow the conductive member 26 to slide, a rail or the like may be provided on the shelf board 16. In this case, since the position of the conductive member 26 can be adjusted according to the thickness of the books 12 to be arranged, more books 12 can be arranged on the bookshelf 14.

  Also in the present embodiment, the electromagnetic wave from the sheet-like antenna 18 travels through the first surface 25 of the conductive member 26 and is emitted from the edge to reach the IC chip of the IC tag 24. Similarly, the electromagnetic wave from the IC tag 24 travels through the first surface 25 of the conductive member 26, is emitted from the edge thereof, and reaches the sheet-like antenna 18. In this way, even when the book 12 is covered with the cover 12d having an electromagnetic wave shielding function, communication is possible between the sheet antenna 18 and the IC tag 24, and information on the IC tag 24 is read. Can do.

  In the present embodiment, the conductive member 26 is installed on the shelf plate 16 of the book shelf 14, but the conductive member 26 may be installed on the back plate 17.

  FIG. 4A to FIG. 4D show the results of an IC tag reading experiment. In this experiment, a wizard UHF band IC tag (UhFINE) was attached to the vicinity of the throat of the book 12 as in FIG. 2, and the book 12 was placed on the sheet-like antenna 18 as in FIG. In this experiment, the conductive member is not inserted into the book 12. The position of the cover 12d with respect to the book 12 was changed, and an experiment was conducted to determine whether the IC tag 24 can be read. The cover 12d was made of aluminum vapor-deposited paper.

  As shown in FIG. 4A, when the front cover and back cover of the book 12 were completely covered with the cover 12d, the IC tag 24 could not be read. Further, as shown in FIG. 4B, the IC tag 24 could not be read even when about half of the front cover and back cover of the book 12 was covered with the cover 12d.

  In this experiment, as shown in FIG. 4C and FIG. 4D, the portion covering the spine of the cover 12d was removed, and an IC tag 24 reading experiment was performed. When the front cover and the back cover of the book 12 were completely covered with the cover 12d as shown in FIG. 4C, the IC tag 24 could be read. On the other hand, as shown in FIG. 4D, when the cover 12d covers about half of the front cover and back cover of the book 12, the IC tag 24 could not be read.

  From the experimental results shown in FIGS. 4A and 4B, when the conductive member is not inserted into the book 12, the front cover, back cover, and back cover of the book 12 are covered with the cover 12d. It can be seen that the IC tag 24 cannot be read. Further, from the experimental result of FIG. 4C, it can be seen that the portion of the cover 12d covering the spine greatly affects whether the IC tag 24 can be read.

  FIG. 5 shows the results of another IC tag reading experiment. Also in this experiment, a UHF band IC tag (UhFINE) manufactured by Wizard was pasted near the throat of the book 12 and the book 12 was placed on the sheet-like antenna 18. In this experiment, the position of the substantially rectangular conductive member with respect to the IC tag 24 was changed, and an experiment was made to determine whether or not the IC tag 24 can be read. The cover 12d was made of aluminum vapor-deposited paper.

  As shown in FIG. 5, the IC tag 24 has an elongated shape, includes an IC chip 24a at the center thereof, and includes antennas 24b on both sides of the IC chip 24a. When the conductive member is disposed at a position away from the IC tag 24 (conductive members 26a and 26e in FIG. 5), the IC tag 24 cannot be read. Further, it can be seen that when one conductive member is arranged so as to overlap the IC chip 24a of the IC tag 24 and the antennas 24b on both sides, the reading performance of the IC tag 24 is deteriorated (the conductive property of FIG. 5). Member 26c). Further, when the conductive member was arranged so as to overlap with a part of the antenna 24b of the IC tag 24 (conductive members 26b and 26d in FIG. 5), the IC tag 24 could be read.

  From the results of this experiment, in order to improve the reading performance of the IC tag 24, it is preferable to dispose the conductive member so as to overlap at least one part of the antenna 24b located on both sides of the IC chip 24a. I understand that. Further, it can be seen that the reading performance of the IC tag 24 is lowered when the conductive member is arranged so as to overlap the IC chip 24a.

  FIG. 6 shows the result of another IC tag reading experiment. Also in this experiment, a UHF band IC tag (UhFINE) manufactured by Wizard was pasted near the throat of the book 12 and the book 12 was placed on the sheet-like antenna 18. In this experiment, the length of the substantially rectangular conductive member with respect to the cover 12d was changed to test whether the IC tag 24 could be read. The conductive member 26 is arranged so as to overlap with at least one part of the antenna 24b located on both sides of the IC chip 24a based on the experimental result described in FIG. The cover 12d was made of aluminum vapor-deposited paper.

  As shown in FIG. 6, when the length of the conductive member is half that of the cover 12d (conductive member 26f in FIG. 6), the IC tag 24 could not be read. On the other hand, when the length of the conductive member was 3/4 or more of the cover 12d (conductive members 26g and 26h in FIG. 6), the IC tag 24 could be read.

  From the results of this experiment, it can be seen that in order to improve the reading performance of the IC tag 24, it is preferable that the length of the conductive member is 3/4 or more of the cover 12d.

  FIG. 7A to FIG. 7E show the results of still another IC tag reading experiment. In this experiment, a UHF band IC tag (AD-233m5) manufactured by Avery Dennison was affixed in the vicinity of the throat of the book 12 as in FIG. 2, and the book 12 was placed on the sheet-like antenna as in FIG. In this experiment, similarly to the experiment described with reference to FIG. 5, the position of the conductive member was changed with respect to the IC tag 24, and an experiment was performed to determine whether or not the IC tag 24 can be read. The cover 12d was made of aluminum vapor-deposited paper.

  The IC tag 24 used in this experiment also has an elongated shape, and includes an IC chip 24a at the center and antennas 24b on both sides of the IC chip 24a. When the conductive member was disposed so as to overlap a part of the antenna 24b of the IC tag 24 (FIG. 7A, FIG. 7B, FIG. 7E), the IC tag 24 could be read. On the other hand, when the conductive member is arranged so as to overlap with the IC chip 24a of the IC tag 24 (FIGS. 7C and 7D), the IC tag 24 cannot be read.

  Similar to the experimental results described with reference to FIG. 5, from the results of this experiment, in order to improve the reading performance of the IC tag 24, it overlaps with at least one part of the antenna 24b located on both sides of the IC chip 24a. It can be seen that it is preferable to dispose a conductive member. Further, it can be seen that the reading performance of the IC tag 24 is deteriorated when one conductive member is disposed so as to overlap the antenna 24b on both sides across the IC chip 24a of the IC tag 24.

  In the above description, communication between the sheet antenna 18 provided on the book shelf 14 and the IC tag 24 in the book 12 has been described. For example, an automatic lending machine, a collection inspection handy reader, a gate antenna, an automatic lending Even when communication is performed between an antenna provided in a machine, automatic return machine, automatic warehouse, etc. and an IC tag in a book, information on the IC tag is suitably read by inserting a conductive member into the book. be able to.
