Description

  The present invention relates to a non-contact type IC card holder for storing a plurality of non-contact type IC cards.

  Conventionally, entrance / exit processing for tickets, commuter passes, etc. has been performed by an input-type automatic ticket checker that inserts magnetic ticket tickets into the automatic ticket checker body. There was an inconvenience that tickets had to be taken in and out. Recently, in order to eliminate such inconvenience, commuter pass etc. is composed of non-contact type IC card with wireless communication function, and data is exchanged with the main body of automatic ticket gate to perform entrance / exit processing As users enter and exit, the convenience of passing a non-contact IC card commuter pass to the antenna of an automatic ticket gate, which is a card reader, has been improved. In addition, since the IC card has a larger storage capacity than the conventional magnetic ticket, in addition to the entrance / exit processing data such as the commuter pass, stored data (SF) is stored in the store provided in the station premises. It is also considered to be used for shopping and eating.

  However, when carrying the above non-contact type IC card, there is no problem if there is only one non-contact type IC card in the card holder for commuter pass etc. In this case, when a plurality of non-contact type IC cards are stacked and stored in the card holder, the magnetic field generated from the antenna of the automatic ticket checker, which is a card reader, causes mutual interference with the plurality of non-contact type IC cards. It is known that inconveniences such as reading and writing of erroneous data are performed, and entry and exit are denied, for example.

Therefore, in order to solve the above inconvenience, “a non-contact type IC card holder having a plurality of card storage units each storing a non-contact type IC card, with a partition wall provided between the card storage units. , A non-contact type IC card holder characterized in that a conductor portion is provided in the partition wall portion, or “first and second magnetic body portions provided with the conductor portion sandwiched in the partition wall portion” With the featured non-contact type IC card holder, it is possible to read and write a desired IC card when the card storage surface on which the desired IC card is stored is placed on or held over a card reader. In addition, a non-contact type IC card holder has been proposed in which an oscillating magnetic field generated from a card reader is blocked by the conductor and does not affect other IC cards (for example, patents) Document reference 1).
JP 2000-268146 A

  However, in the non-contact type IC card holder described in the above-mentioned patent document, each non-contact type IC card accommodated with the conductor portion interposed therebetween is in a state of being electromagnetically coupled to an oscillating magnetic field generated from the card reader. Data was exchanged automatically when entering the communication area, and data was sent and received unexpectedly from cards that were not intended to be used, possibly resulting in damage. In the case of a commuter pass, the non-contact type IC card holder is not held from the front with respect to the card reader antenna. There was also a situation where inconveniences such as entry and exit were refused.

  Accordingly, an object of the present invention is to solve the above-mentioned problem, and when carrying a plurality of non-contact type IC cards, unintentional data exchange is not performed when not in use, and simple operation at the time of use. Accordingly, it is an object of the present invention to provide a non-contact type IC card holder that can exchange data only with a desired non-contact type IC card.

In order to solve the above-mentioned problems, the invention of claim 1 is a card holder made of a non-conductive material capable of storing and taking out two non-contact type IC cards, respectively, and a conductor plate made of a single conductive material. A conductive plate holder made of a non-conductive material, and when the data is not read or written to the non-contact type IC card, the conductive film holder is placed between the two card holders. When the body plate holder is overlapped, the card holder and the conductor plate holder are bound so as to be able to be spread apart, and when reading or writing data to the non-contact type IC card, Rotate the card holder containing the non-contact type IC card for reading and writing in a double-sided manner and superimpose it on the other card holder It is a non-contact type IC card holder, characterized in that possible are organized.

  The non-contact type IC card holder of the present invention can be obtained by positioning a conductor plate holder between two card holders when not in use when carrying a plurality of non-contact type IC cards. Is very close to the conductor plate, so each contactless IC card is not electromagnetically coupled to the oscillating magnetic field generated from the card reader, and there is no unintentional data exchange, making it extremely easy to operate That is, only the desired non-contact type IC card is operated by rotating the desired non-contact type IC card to the other non-contact type IC card and rotating the desired non-contact type IC card over the card reader. Can transmit and receive data by electromagnetically coupling to the oscillating magnetic field generated from the card reader, preventing damage caused by incorrect data transfer There is a result.

  Further, even if the non-contact type IC card holder is held up against the antenna of the card reader in an oblique direction or the like, the undesired non-contact type IC card is very close to the conductor plate. In the case of a commuter pass or the like, there is no inconvenience that entry / exit is refused.

Non-contact type IC card holder is a non-conductive type card holder made of a non-conductive material capable of storing and taking out two non-contact type IC cards, respectively, and a conductive plate made of a single conductive material. A conductor plate holder made of a material is overlapped, and the card holder and the conductor plate holder are bound so that they can be spread on one side.
FIG. 1 is a perspective view for explaining an embodiment of a non-contact type IC card holder according to the present invention, in which a long plastic sheet is folded in half at both outer ends, and one end side is a card holder open edge 14. The other three sides are welded to form card holder welded edges 11, 12 and 13, which are formed in a pocket shape by the card holder outer wall 5 and the card holder inner wall 6 and are not in contact with the card holder open edge 14 Similarly to the card holder 2 in which the type IC card A can be inserted and removed, one end side is the card holder open end edge 18 and the other three end sides are welded to form card holder weld end edges 15, 16, and 17, respectively. The card holder outer wall 7 and the card holder inner wall 8 form a pocket, and the non-contact type IC card B is taken out from the open end edge 18 of the card holder. The card holder 3 and the long plastic sheet that can be made are folded in half, and the three sides are welded to form the conductor plate holder welded edges 19, 20, 21 to form the conductor plate holder constituting wall 9 And 10 is accommodated in the conductive plate holder welding edge 22 between the card holders 2 and 3 after the conductive plate C is accommodated in the conductive plate holder 4 formed into a pocket shape by 10 and 10 and then opened. A sealed non-contact type IC card holder 1 is shown.

  The card holders 2 and 3 and the conductor plate holder 4 are both non-contact type IC cards that are normally used and have a rounded square shape. The other side is welded and has an internal volume for accommodating the non-contact type IC card and the conductor plate. The conductor plate holder 4 may be configured to weld four sides and enclose the conductor plate. As a material, a non-conductive material that allows radio waves to pass through, for example, a soft vinyl chloride resin sheet is optimal for processing of plastic, and a sheet thickness in the range of 0.3 mm to 1.0 mm is preferable. Moreover, leather, cloth, etc. can also be used from the use surface, such as a commuter pass. Furthermore, a holder made of a hard plastic molded product using a vacuum molding method or an injection molding method may be used.

  When carrying a plurality of non-contact type IC cards, the conductor plate C blocks the non-contact type IC card from being electromagnetically coupled to the oscillating magnetic field generated from the card reader. For example, a metallic material such as aluminum, copper, iron, nickel, or an alloy material such as tinplate can be used. The shape and size of the conductor plate C are in order to cut off the oscillating magnetic field by covering the antennas of the non-contact type IC cards A and B (a loop antenna formed by the size of the card surface with a flat antenna). It is desirable to have a size equal to the card surface of the non-contact type IC cards A and B. A thin foil-like sheet may be used, but in view of durability such as bending, a plate-like sheet is desirable.

  FIG. 2 is a cross-sectional view showing the non-contact type IC card holder 1 of the embodiment shown in FIG. 1 in a folded state when not in use, with card holder outer walls 5 and 7 and card holder inner walls 6 and 8 respectively. The non-contact type IC cards A and B accommodated in the formed pocket-shaped card holders 2 and 3 are adjacent to the conductor plate C enclosed between the conductor plate holder constituting walls 9 and 10 in a stacked manner. ing. For this reason, the oscillating magnetic field generated from the antenna coil T formed on the antenna substrate U of the card reader R is canceled by the eddy current generated by the conductor plate C, and is electromagnetically coupled to the antenna S of the non-contact type IC cards A and B. No data is read from or written to the non-contact type IC cards A and B from the card reader R side.

  FIG. 3A is a cross-sectional view for explaining the use state of the non-contact type IC card A of the non-contact type IC card holder 1 of the embodiment shown in FIG. From the folded state of the non-contact type IC card holder 1, the card holder 2 is rotated in a double-spread shape with the conductive plate holder welding edge 22 as the center line, and is laminated on the card holder 3 side in a stacked manner. The IC card A side, that is, the card holder inner wall 6 side of the card holder 2 is held over the card reader R. At this time, the non-contact type IC card B has a conductor plate holder constituting wall as described above. Since the conductor plate C enclosed between 9 and 10 is close to the laminated plate, the oscillating magnetic field generated from the antenna coil T formed on the antenna substrate U of the card reader R is a vortex generated by the conductor plate C. Canceled by its flow, the antenna S of the non-contact type IC card B does not electromagnetically coupled, reading and writing of data to the non-contact type IC card B from the card reader R side is not performed. The non-contact type IC card A is not close to the conductor plate C via the non-contact type IC card B, and between the non-contact type IC card B by the card holder outer walls 5 and 7, respectively. Since there is a slight gap formed, the oscillating magnetic field generated from the antenna coil T formed on the antenna substrate U of the card reader R forms a magnetic path with the non-contact type IC card A, The antenna coil S of the non-contact type IC card A is electromagnetically coupled, and data is read from and written to the non-contact type IC card A from the card reader R side. The slight gap formed between the non-contact type IC cards A and B is preferably a gap having a thickness of about 1 mm due to the lamination of the card holder outer walls 5 and 7.

From the folded state of the non-contact type IC card holder 1 of the embodiment, the card holder 3 is rotated in a double-sided manner with the conductor plate holder welding edge 22 as the center line, and is stacked on the card holder 2 side, The non-contact type IC card B side, that is, the card holder inner wall 8 side of the card holder 3 is held over the card reader R, and the non-contact type IC card B is not in contact with the conductor plate C. Since there is a slight gap formed by the card holder outer walls 5 and 7 between the IC card A and the non-contact type IC card A, the antenna board of the card reader R is provided. U An oscillating magnetic field generated from the formed antenna coil T forms a magnetic path with the non-contact type IC card A, and is electromagnetically coupled with the antenna coil S of the non-contact type IC card A, and from the card reader R side. Data is read from or written to the non-contact type IC card A. At this time, since the non-contact type IC card A is close to the conductor plate C enclosed between the conductor plate holder constituting walls 9 and 10 as described above, it is non-contact from the card reader R side. Data is not read from or written to the contact IC card A.

Although illustration is omitted, for example, when the non-contact type IC card A is used, in a state where the non-contact type IC card A is held over the card reader, the non-contact type IC card B is close to the conductor plate C, and each A gap is formed between the non-contact type IC cards A and B by stacking the card holder outer walls 5 and 7, the cover inner walls 30 and 32, and the cover outer walls 29 and 31 by rotating the holder and the cover in a spread form. Therefore, the magnetic path formation with the non-contact type IC card A is reliably performed by the oscillating magnetic field generated from the antenna coil T formed on the antenna substrate U of the card reader R, and the non-contact type IC card is formed from the card reader side. Data is read from and written to A. According to this development example, not only a non-contact type IC card can be carried, but also the surface of the cover outer wall 29 and the cover outer wall 31 can be printed, so that the appearance of a commuter pass can be made.
