Description

  The present invention relates to an information recording medium on which information is recorded, and more particularly to an information recording medium on which information is recorded by two types of means.

  Trading cards are popular as cards that are printed with various different types of patterns printed and intended for exchange and collection. Trading cards are printed with athletes, cartoon characters, etc., and users collect cards of their choice while exchanging (trading) cards between them and using them to increase friendship. Yes.

  In addition to the original way of playing such as collecting and exchanging, interpersonal games using trading cards are also popular. In the interpersonal game, the parameters given as visible information to the trading cards are compared to compete for winning or losing.

  Further, in recent years, not only the interpersonal battle type but also the computer battle type game has become widespread. In this method, a computer is made to recognize parameters assigned to a trading card and a battle game is played. Generally, it is installed in an amusement facility or the like in the form of a housing integrated with a monitor or card reader.

  As a technique for causing a computer to recognize parameters assigned to a trading card, there is a method of printing a code such as a one-dimensional code or a two-dimensional code on a card. By making the machine recognize this information, the card and the game machine are linked. The advantage of this technology is that cards can be manufactured at a relatively low cost. On the other hand, since this technology is printed information, there is a problem in that it is difficult to overwrite and change information (for example, a character on a game is upgraded) in conjunction with a computer. Further, since the information is printed, there is a problem that the code pattern can be analyzed. In some game machines, there are problems such as enthusiastic enthusiasts publishing code patterns on the Internet.

  Attempts have been made to convert trading cards to IC cards as an alternative to printing one-dimensional codes and two-dimensional codes. The advantage of this technology is that the user memory in the IC card can be overwritten and changed, unlike printed one-dimensional codes and two-dimensional codes. In addition, since an IC card capable of wireless communication compliant with the NFC (Near Field Communication) standard can be linked with not only a game case but also a mobile device such as a smartphone, an unprecedented game plan can be made. . Further, if the IC card can set an access password to the user memory, it is possible to prevent creation of a forged card by an enthusiast.

  On the other hand, this technique has a problem that IC cards are more expensive than non-IC cards and thus are not widely used. There are also games against the computer that use IC cards, but this is only using IC cards to manage the save data of the game. IC card.

  In addition, a technique has been proposed in which a game is played using a card in which a sticker on which a two-dimensional code is printed or a sticker in which an RFID chip is embedded can be replaced (see Patent Document 1).

JP 2008-125973 A

  If an IC card can be provided at a relatively low cost, it will be possible to disseminate games that have never been planned in the anti-computer game market, but manufacturing IC cards with embedded IC chips is costly. There is a problem. As an IC card that can be provided at a relatively low cost, it is conceivable to attach an IC tag label to a conventional non-IC card. The IC tag label is a label including an IC chip and an antenna, and is a non-contact type storage unit capable of non-contact communication of stored information. However, there is a demerit that the one-to-one correlation between the card pattern and the IC memory information cannot be secured because the user can easily peel it off and attach it to another card simply by attaching the IC tag label.

  A trading card is originally a card for exchanging cards between friends to deepen exchanges. However, since the one-to-one correlation between the card picture and the IC memory information cannot be ensured, fraud at the time of card exchange is allowed, which hinders the spread of trading cards. Specifically, when exchanging cards of the same value between friends, one handed a regular card, but the other handed a card with an IC tag label replaced with a low-value card. A situation that cannot be understood in the field can occur. In particular, in recent years, there are cases where trading is conducted at an online auction or the like, which may later lead to serious troubles such as lawsuits.

<1. Configuration of information recording medium>
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing an information recording medium according to an embodiment of the present invention. In FIG. 1, 1 is a base material, 2 is an adhesive layer, 3 is an IC inlet, 4 is a protective sheet, 5 is a printing layer, and 10 is an information recording medium. 1A is a plan view of the information recording medium 10, and FIG. 1B is a cross-sectional view corresponding to AA in FIG. 1A, showing a layer structure.

  Fig.1 (a) has shown the back surface on the opposite side to the surface on which the pattern etc. were printed. As shown in FIG. 1A, in the information recording medium 10, the IC inlet 3 is attached to one surface (back surface) of the substrate 1, and the printed layer 5 is formed so as to overlap with a part of the IC inlet 3. Has been. The information recording medium 10 records information by two types of means, that is, an IC chip in the IC inlet 3 and a code expressed on the print layer 5. The IC inlet 3 is a non-contact type storage unit capable of non-contact communication of stored information. In the example of FIG. 1A, the antenna coil pattern of the IC inlet 3 is shown. However, since the protective sheet is actually provided so as to cover the IC inlet 3, the IC inlet 3 is seen from the plane. Cannot be seen directly.

  As shown in FIG. 1B, in the information recording medium 10, an IC inlet 3 is attached to one surface of the substrate 1 with an adhesive layer 2. Further, a protective sheet 4 is formed via an adhesive layer 2a so as to protect the entire surface of the IC inlet 3. Furthermore, the printing layer 5 is formed over a part of the protective sheet 4 and a part of the substrate 1. In FIG. 1 (b), the thickness direction (vertical direction in the drawing) is shown thicker than the width in the plane direction (horizontal direction in the drawing) in order to clearly explain the layer configuration. While the width of the information recording medium 10 is several centimeters, the thickness from the substrate 1 to the printing layer 5 is about 1 mm to 2 mm.

  The IC inlet is sometimes called “IC inlay”, “RFID inlet”, “RFID inlay”, or the like. The IC inlet 3 is a circuit having a function of performing wireless communication. In this embodiment, the IC inlet 3 is in the form of an IC inlet in which an IC chip and an antenna for realizing wireless communication by RFID (Radio Frequency IDentification) are incorporated. This IC inlet is realized, for example, by arranging an IC chip and an antenna on an inlet base material.

  Various plastic films can be used as the inlet base material. For example, polyethylene terephthalate (PET), PET-G (terephthalic acid-cyclohexanedimethanol-ethylene glycol copolymer), polyvinyl chloride (PVC), vinyl chloride-vinyl acetate copolymer, polycarbonate, polyamide, polyimide, cellulose diester A single film such as acetate, cellulose triacetate, polystyrene, ABS, polyacrylic ester, polypropylene, polyethylene, polyurethane, or a composite film thereof can be used.

  As the IC inlet 3 for realizing the non-contact type storage unit, various forms can be used. In the present embodiment, an IC inlet having a frequency suitability of UHF (Ultra High Frequency) band, particularly 860 MHz to 960 MHz is employed. By adopting an IC inlet having a frequency suitability of 860 MHz to 960 MHz, output adjustment can be easily controlled. Therefore, the communication distance can be set up to about several centimeters to several meters, and can be adjusted according to the structure of the game machine.

  The information recording medium 10 according to this embodiment has a function as a non-contact type IC card. By sticking the IC inlet to the base material 1 which is a non-IC card, a function as a non-contact type IC card is provided. The IC inlet is a part that is generally the basic configuration of an IC tag. An IC tag is a contactless storage unit that communicates with the outside through a built-in antenna and transmits information recorded on an IC chip, and is also called an electronic tag, a wireless tag, an RFID tag, or the like. . UHF band IC tags can communicate over a relatively long distance compared to other frequency bands such as a medium wave band, a short wave band, and a microwave band. In the present embodiment, by adopting an IC inlet having a frequency suitability of 860 MHz to 960 MHz, which is a UHF band, as the IC inlet 3, it is possible to perform wireless communication over a relatively long distance.

  As IC inlets, there are a passive system without a built-in battery and an active system with a built-in battery. In consideration of portability as a trading card, a passive system without a built-in battery is preferable. Moreover, as an IC inlet, either an electromagnetic induction method or a radio wave method may be adopted, but an electromagnetic induction method is adopted.

  Any IC inlet 3 that realizes a non-contact type storage unit may be used as long as it satisfies the above-described conditions. For example, ALN-9661 manufactured by Alien Technology is used. Can do.

  The substrate 1 is a substrate serving as a card carrier, and the material thereof is not particularly limited. For example, polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), acrylonitrile- Examples of commonly used plastic materials such as butadiene-styrene copolymer (ABS), paper such as art paper, coated paper, synthetic paper, etc. may be used, and these materials may be used alone or in combination. . When forming the printing layer 5 by the thermal transfer method, it is preferable to use paper or polyvinyl chloride.

  The adhesive used for the adhesive layers 2 and 2a will be described. The adhesive includes various types such as a solvent type, a polymerization type, an ultraviolet curable type, an emulsion type, and a heat melting type, and is a concept including a so-called adhesive in this specification. The pressure-sensitive adhesive maintains an intermediate tack state without significantly increasing the viscosity. The adhesive resin composition includes natural rubber, nitrile rubber, epoxy resin, vinyl acetate emulsion, polyester, acrylic, acrylate copolymer, polyvinyl alcohol, phenol resin, etc. These various materials can be used.

  As the protective sheet 4, various plastic films and paper base materials can be used. As the plastic film, those similar to those used for the inlet base material can be used, and as the paper base material, craft paper, glassine paper, synthetic paper, latex, melamine-impregnated paper, or the like can be used. When performing printer printing on the surface, paper substrates such as fine paper, coated paper, and synthetic paper are particularly preferable.

<2. Manufacture of information recording media>
Next, a method for manufacturing the information recording medium according to the present embodiment will be described. FIG. 2 is a flowchart showing a method for manufacturing the information recording medium according to the present embodiment. First, as the IC inlet 3, an IC inlet that is a non-contact type storage unit in which an IC chip and an antenna are incorporated is prepared (step S1). An IC pattern may be incorporated by forming an antenna pattern on the inlet base material made of the above material, or an already completed IC inlet may be purchased.

  Next, an IC inlet (non-contact type storage unit) is attached to the base material (step S2). Specifically, first, an adhesive is applied on the substrate 1, and the IC inlet 3 is disposed thereon. Then, the adhesive is solidified to form the adhesive layer 2. As a result, the IC inlet 3 is affixed to the substrate 1.

  Subsequently, a protective sheet is stacked on the non-contact recording medium (step S3). Specifically, an adhesive is applied onto the IC inlet 3, and alignment is performed, and the protective sheet 4 is placed on the adhesive. Then, the adhesive is solidified to form the adhesive layer 2a. Thereby, the protection sheet 4 is formed so as to cover the IC inlet 3. When using an adhesive as an adhesive, the adhesive may be applied to the protective sheet 4 and the protective sheet 4 may be laminated with the adhesive application surface facing the IC inlet 3 side.

  Next, a printed layer expressing a predetermined code is formed on the base material and the protective sheet (step S4). Specifically, a two-dimensional code is printed over the substrate 1 and the protective sheet 4 by a thermal transfer type card printer to form the print layer 5. When the inlet base material and the protective sheet 4 are transparent materials, white may be printed as a base of the two-dimensional code, and the two-dimensional code may be printed thereon to form the print layer 5.

<3. Example>
The following were adopted as each component.
Base material 1 ... Polyvinyl chloride (PVC) card having a thickness of 0.76 mm Adhesive for forming adhesive layers 2 and 2a "DUROTAK PZ084A manufactured by Henkel Technologies Japan" (adhesive)
IC inlet 3 “ALN-9661 made by Alien Technology”
Protective sheet 4 ... "Chrispa" manufactured by Toyobo

  The visibility of the printed layer 5 formed by the thermal transfer type card printer is good, and when it is optically read using a two-dimensional code reader mounted on a portable terminal, the recording information of the two-dimensional code is obtained. I was able to.

<4. Use of information recording media>
An information recording medium 10 in which the recording information of the two-dimensional code expressed on the printing layer 5 is the same as the recording information in a predetermined memory in the IC chip of the IC inlet 3 is used as a trading card that can be used in a game machine. FIG. 3 is a functional block diagram of a game machine that uses the information recording medium according to the present embodiment. Each component shown in FIG. 3 is provided inside the housing of the game machine.

  The light emitting unit 21 emits light having a wavelength in the range from visible light to infrared, and is realized by a diode or the like that emits light having a predetermined wavelength (600 nm to 900 nm). The light receiving unit 22 is realized by a CCD or the like capable of sensing light having a wavelength in the range of visible light to infrared light. The IC reading unit 23 performs wireless communication with the IC inlet and reads recorded information in the IC chip, and is realized by a non-contact type IC reader. The authentication information storage unit 24 stores authentication information for comparison with the recording information of the print layer 5 and the IC inlet 3, and is realized by a known storage unit such as a flash memory. The authentication means 25 analyzes the image of the code obtained from the light receiving unit 22 to acquire recording information, and acquires the recording information read from the IC inlet 3 by the IC reading unit 23. Determine whether. Further, when the recording information obtained from the light receiving unit 22 and the recording information obtained from the IC reading unit 23 match, authentication is performed by comparing with the authentication information stored in the authentication information storage unit 24. . The authentication unit 25 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and is realized by the CPU executing a predetermined program. The game machine control means 26 is means for controlling the game machine in accordance with a signal from the authentication means 25. Specifically, when the authentication by the authentication unit 25 is successful, the screen of the game machine is unlocked and an instruction by an operation button (not shown) can be accepted.

  A user inserts a trading card into a card insertion slot provided in a case of the game machine. Then, in the trading card, the light emitted from the light emitting unit 21 hits in the housing of the game machine, the printing layer 5 is positioned at a position where the light receiving unit 22 can be reflected, and the IC reading unit 23 can read the recorded information. The trading card is arranged so that the IC inlet 3 is located at the position. Specifically, it is arranged at a position as shown in FIG.

  In the game machine, the light emitting unit 21 shines light on the trading card taken into the housing. Then, the light receiving unit 22 receives reflected light from the printing layer 5. The received light is converted into an electrical signal and sent to the authentication means 25 as a code image on the print layer 5. The authentication unit 25 converts the code image according to a predetermined rule, and obtains recorded information. In addition, in the game machine, the IC reading unit 23 reads the recorded information in the memory in the IC chip incorporated in the IC inlet 3 in parallel. Acquisition of recording information from the printing layer 5 and acquisition of recording information from the IC inlet 3 may be performed simultaneously or sequentially one by one. When performing one by one in sequence, either acquisition of recording information from the printing layer 5 or acquisition of recording information from the IC inlet 3 may be performed first.

  The authentication unit 25 compares the record information acquired from the print layer 5 with the record information acquired from the IC inlet 3. As a result of the comparison, if the two match, the authentication unit 25 performs authentication by comparing with the authentication information stored in the authentication information storage unit 24. As the authentication information, for example, the same information as the recording information of the code expressed in the printing layer 5 and the recording information of the IC inlet 3 is stored. When the matched recording information and authentication information further match, an authentication success signal is transmitted to the game machine control means 26. When the game machine control means 26 receives the authentication success signal from the authentication means 25, it sets the game machine to a usable state. Specifically, a signal is transmitted to a display control unit (not shown) to release the screen lock, and a state in which an instruction from the operation button can be accepted. If an authentication failure signal is received from the authentication means 25, the game machine control means 26 does not set the game machine to a usable state and keeps it unusable, indicating that the inserted card is not a valid card. Display on the display.

  The IC inlet 3 is not embedded in the base material 1 but only attached to the base material 1. For this reason, it peels from the base material 1 and can also affix another IC inlet. When the information recording medium thus modified is used as a trading card and inserted into a game machine, the game machine reads the recorded information in the memory in the IC chip incorporated in the IC inlet by a non-contact type IC reader. I can. However, since only about half of the two-dimensional code remains on the information recording medium, the recording information cannot be acquired from the two-dimensional code. For this reason, the game machine does not set the game machine to a usable state, leaves it unusable, and displays that the inserted card is not a valid card.

  A case will be described in which someone attempts to modify the information recording medium 10 by peeling the IC inlet 3 from the base material 1 and attaching another IC inlet. FIG. 4 is a diagram showing a state where the IC inlet 3 is peeled from the regular information recording medium 10. As shown in FIG. 4, when the IC inlet 3 is peeled off, only the portion of the printed layer 5 directly formed on the substrate 1 remains on the substrate 1. FIG. 5 is a diagram illustrating a state where an IC tag including another IC inlet is attached. As shown in FIG. 5, when another IC tag 13 is affixed, the printed layer 5 is only a portion directly formed on the base material 1, so the printed layer 5 is not restored to the original state. As shown in FIG. 5, only half of the two-dimensional code remains on the information recording medium 10 to which the other IC tag 13 is attached. For this reason, it has become obvious at a glance that the image has been tampered (modified), and authenticity determination can be easily performed.

  The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, a two-dimensional code is used as a code to be expressed on the print layer 5, but various codes such as a barcode that is a one-dimensional code can be used.

  Further, in the above embodiment, when the code recording information and the IC recording information match in the game machine, the authentication is further performed by comparing with the authentication information. The authentication may be successful only when the information matches.
