Is housed in.

  The antenna coil 21 has a first coil loop portion 211 and a second coil loop portion 212. The first coil loop portion 211 is disposed along the upper lid 13, and the second coil loop portion 212 is disposed along the lower lid 14. In addition, the first coil loop portion 211 and the second coil loop portion 212 sandwich the circuit board 22 as an electromagnetic shield provided on the straight line CL that penetrates the first coil loop portion 211 and the second coil loop portion 212.

The parts 212 are arranged in parallel to the second plane on which the part 212 is located.

  FIG. 3 shows functional blocks of the toy 10.

  The toy 10 includes a communication unit 31, an operation unit 32, a storage unit 33, a control unit 34, a power supply unit 35, and an operation unit 36.

  The communication unit 31 is configured by the non-contact communication device 20 having the signal processing circuit 23 mounted on the antenna coil 21 and the circuit board 22, and transmits signals to and from the information holding medium 100. The operation unit 32 includes a sound generator such as a speaker and a light emitting element such as an LED, and is configured to output an effect including at least one of sound and light. The storage unit 33 includes a ROM and the like, and stores a plurality of operation data for operating the operation unit 32 in association with electronic information held in the information holding medium 100. In addition, the operation unit 32 can also include a display body using a display medium or the like, an operation mechanism using a motor, or the like.

  The control unit 34 is configured mainly with a CPU, and controls the communication unit 31, the operation unit 32, and the storage unit 33 in an integrated manner. The control unit 34 operates the operation unit 32 based on operation data corresponding to the electronic information acquired from the information holding medium 100 by the communication unit 31 among the plurality of operation data stored in the storage unit 33.

  The power supply unit 35 supplies operating power to the communication unit 31, the operation unit 32, the storage unit 33, and the control unit 34. The operation unit 36 includes a power switch and a switch that instructs the control unit 34 to start communication by the communication unit 31.

  An information holding medium 100 that communicates with the toy 10 includes an antenna coil 101 and an IC 102, and electronic information is held in the IC 102.

  Communication between the toy 10 and the information holding medium 100 is performed as follows.

  When an instruction to start communication is given by operating the switch of the operation unit 36, an alternating current is supplied to the antenna coil 21 of the toy 10, and an alternating magnetic field is formed around the antenna coil 21. An induced electromotive force is generated in the antenna coil 101 of the information holding medium 100 arranged in the alternating magnetic field, and a current flows, so that the IC 102 to which the antenna coil 101 is connected is driven. Then, a signal modulated based on the electronic information held in the IC 102 is put on an alternating magnetic field, transmitted from the antenna coil 101 of the information holding medium 100 to the antenna coil 21 of the toy 10, and received by the antenna coil 21. The signal is demodulated by the signal processing circuit 23, and electronic information is extracted.

  The alternating magnetic field formed around the antenna coil 21 is a combination of the alternating magnetic field formed by the first coil loop portion 211 and the alternating magnetic field formed by the second coil loop portion 212. As described above, the first coil loop portion 211 and the second coil loop portion 212 are wound around the straight line CL in the same direction and connected to the signal processing circuit 23 of the circuit board 22 in series with each other. The phases of the alternating magnetic field formed by the first coil loop portion 211 and the alternating magnetic field formed by the second coil loop portion 212 are the same and reinforce each other.

  However, as shown in FIG. 2, the circuit board 22 as an electromagnetic shield is disposed between the first coil loop portion 211 and the second coil loop portion 212, and the first coil loop portion 211 and the second coil loop portion 211 are arranged. When the magnetic flux of the alternating magnetic field of each of the coil loop portions 212 penetrates the circuit board 22, an eddy current is generated in a conductor portion of the circuit board 22 such as a circuit pattern. The eddy current generates a magnetic flux opposite to the magnetic flux penetrating the circuit board 22, and the strength of the alternating magnetic field formed around the antenna coil 21 can be reduced by the magnetic flux caused by the eddy current.

  However, since the first coil loop portion 211 and the second coil loop portion 212 are arranged with the circuit board 22 interposed therebetween, either side of the first coil loop portion 211 side and the second coil loop portion 212 side is arranged. However, the magnetic field strength required for communication with the information holding medium 100 can be maintained. If the antenna coil 21 is configured only by the first coil loop portion 211 that is disposed in the vicinity of the upper lid 13 of the housing 11 (in this embodiment, disposed along the upper lid 13), the housing 11 on the side of the lower lid 14, the strength of the alternating magnetic field is remarkably reduced, and communication becomes impossible.

  Next, a preferred configuration example of the antenna coil 21 will be described with reference to FIGS.

  From the viewpoint of increasing the magnetic field strength and symmetry of the alternating magnetic field around the antenna coil 21, the first coil loop portion 211 and the second coil loop portion 212 preferably have similar loop shapes, and more preferably, As shown in FIG. 2, it has the same loop shape.

  For example, in the example shown in FIG. 4, the loop shape of the first coil loop portion 211 is a substantially rectangular shape, and the loop shape of the second coil loop portion 212 is a substantially circular shape. When the loop shapes of the second coil loop portion 212 and the second coil loop portion 212 are different from each other, a non-overlapping region R is generated in the overlap of the first coil loop portion 211 and the second coil loop portion 212. In this non-overlapping region R, the first coil loop portion 211 and the second coil loop portion 212 cancel each other out of the AC magnetic field, and the strength of the AC magnetic field formed around the antenna coil 21 is reduced, that is, the communication sensitivity is reduced. Can occur. Further, the non-overlapping region R is not circularly symmetric with respect to the central axis of each of the first coil loop portion 211 and the second coil loop portion 212, and the symmetry of the alternating magnetic field formed around the antenna coil 21 is not. Disturbance, that is, disturbance of communication sensitivity distribution may occur.

  The first coil loop portion 211 and the second coil loop portion 212 are formed in a similar loop shape, and the same loop shape, so that the non-overlapping region R is reduced and formed around the antenna coil 21. The magnetic field strength and symmetry of the alternating magnetic field can be increased.

  Further, from the viewpoint of increasing the magnetic field strength and symmetry of the alternating magnetic field around the antenna coil 21, the first coil loop portion 211 and the second coil loop portion 212 are preferably arranged parallel to each other and on the same axis.

  For example, in the example shown in FIG. 5, the central axes of the first coil loop part 211 and the second coil loop part 212 are shifted in parallel with each other, and the first coil loop part 211 and the second coil loop part 212 In the overlap, a non-overlapping region R is generated, and as described above, the strength of the alternating magnetic field formed around the antenna coil 21 may be reduced and the symmetry may be disturbed. Similarly, when the central axes of the first coil loop portion 211 and the second coil loop portion 212 are inclined with respect to each other, the strength of the alternating magnetic field formed around the antenna coil 21 may be reduced and the symmetry may be disturbed. .

  By arranging the first coil loop portion 211 and the second coil loop portion 212 on the same axis and in parallel with each other, the non-overlapping region R is reduced and the magnetic field strength of the alternating magnetic field formed around the antenna coil 21 and Symmetry can be increased.

  Also, as shown in FIG. 6, from the viewpoint of increasing the magnetic field strength of the alternating magnetic field around the antenna coil 21, the circuit board 22 is preferably a straight line CL that penetrates the first coil loop portion 211 and the second coil loop portion 212. When viewed in the extension direction (see FIG. 2), they are arranged inside the first coil loop portion 211 and the second coil loop portion 212. By arranging the circuit board 22 inside the first coil loop part 211 and the second coil loop part 212, a part of the magnetic flux of the alternating magnetic field of the first coil loop part 211 and the second coil loop part 212 is changed to a circuit. Without passing through the substrate 22, it can pass by the side of the circuit substrate 22, and the magnetic field strength of the alternating magnetic field around the antenna coil 21 can be increased.

  Next, a usage example of the toy 10 will be described with reference to FIGS.

  FIG. 7 shows an example of an information holding medium.

  The information holding medium shown in FIG. 7 is a medal 100A formed in a substantially disc shape, and a tag 103 in which an antenna coil 101 (see FIG. 3) and an IC 102 (see FIG. 3) are integrated is embedded in the medal 100A. ing.

  The upper lid 13 of the toy 10 is provided with a mounting portion 16 on which the medal 100A is mounted. The mounting portion 16 includes a pair of guide rails 161 extending in parallel, and a groove 104 corresponding to the pair of guide rails 161 is provided on the lower surface of the medal 100A. The medal 100A is guided to the pair of guide rails 161 and disposed at a predetermined position of the upper lid 13, and the tag 103 of the medal 100A is disposed in the vicinity of the upper lid 13 (in this embodiment, it is disposed along the upper lid 13). The first coil loop unit 211 is disposed in a fixed positional relationship.

  As shown in FIG. 8A, when an instruction to start communication is given by a switch operation of the operation unit 36 (see FIG. 3) of the toy 10 with the medal 100A mounted on the mounting unit 16, the toy 10 The control unit 34 (see FIG. 3) operates the communication unit 31 (see FIG. 3). The communication unit 31 exchanges signals between the antenna coil 21 and the tag 103 of the medal 100 </ b> A, and acquires electronic information held in the tag 103.

  Then, the control unit 34 reads operation data corresponding to the electronic information acquired by the communication unit 31 from the storage unit 33 (see FIG. 3), and operates the operation unit 32 (see FIG. 3) based on the read operation data. Let Thereby, the operation unit 32 outputs an effect including at least one of sound and light. As an example of the production, the medal 100A is given a different character pattern for each medal, and a sound including the character name “medal monster” is output.

  In the example shown in FIG. 8A, the tag 103 of the medal 100A is arranged on the upper lid 13 side of the toy 10 adjacent to the first coil loop portion 211 of the antenna coil 21, but as described above, Since the magnetic field strength necessary for communication is maintained on the lower lid 14 side of the toy 10 adjacent to the two-coil loop portion 212, the medal 100A is placed on the lower lid 14 side as shown in FIG. Even when the tag 103 is arranged, the communication unit 31 can acquire electronic information by exchanging signals between the antenna coil 21 and the tag 103 of the medal 100A.

  Note that the tag 103 of the medal 100A arranged on the upper lid 13 side when the medal 100A is attached to the attachment portion 16 is arranged in a fixed positional relationship with respect to the first coil loop portion 211 provided adjacent to the upper lid 13. Is done. On the other hand, it is also assumed that the lower lid 14 is not provided with a mounting portion on which the medal 100A is mounted, and information holding media having various shapes other than the medal 100A are arranged on the lower lid 14 side. Thus, the positional relationship between the information holding medium arranged on the lower lid 14 side and the second coil loop portion 212 provided adjacent to the lower lid 14 is not constant. For this reason, it is preferable to make the magnetic field strength on the lower lid 14 side higher than the magnetic field strength on the upper lid 13 side, and it is preferable to relatively increase the number of turns of the second coil loop portion 212. Further, it is allowed to relatively reduce the number of turns of the first coil loop portion 211.

  The usage example of the toy 10 shown in FIG. 9 uses both the above-mentioned medal 100A and the sub-toy 100B imitating a gun as an information holding medium. As with the tag 103 of the medal 100A, a tag 105 in which an antenna coil and an IC are integrated is embedded in the sub toy 100B.

  The tag 103 of the medal 100A is arranged on the upper lid 13 side of the toy 10, and the tag 105 of the sub toy 100B is arranged on the lower lid 14 side of the toy 10, and the operation unit 36 of the toy 10 (see FIG. 3) When an instruction to start communication is given by a switch operation, the control unit 34 (see FIG. 3) of the toy 10 operates the communication unit 31 (see FIG. 3). The communication unit 31 exchanges signals between the antenna coil 21 and the tag 103 of the medal 100 </ b> A and the tag 105 of the secondary toy 100 </ b> B, and acquires the electronic information held in the tag 103 and the tag 105. Specifically, the medal 100A and the tag 103 are arranged in a fixed positional relationship with respect to the first coil loop portion 211 adjacent to the toy 10 on the upper lid 13 side (arranged in the vicinity of the upper lid 13). The signal of the tag 103 is exchanged with the communication unit 31 by the first coil loop unit 211. The sub toy 100B and the tag 105 are connected to the communication unit 31 by the second coil loop unit 212 adjacent to the toy 10 on the lower lid 14 side (arranged in the vicinity of the lower lid 14). Give and receive. Note that electronic information can be acquired from the tag 103 and the tag 105 without collision by applying a known anti-collision technology in reading RFID (Radio Frequency Identifier).

  Then, the control unit 34 reads operation data corresponding to the combination of the electronic information of the tag 103 and the electronic information of the tag 105 acquired by the communication unit 31 from the storage unit 33 (see FIG. 3), and adds the read operation data to the read operation data. Based on this, the operation unit 32 (see FIG. 3) is operated. Thereby, the operation unit 32 outputs an effect including at least one of sound and light. As an example of the production, the sub toy 100B having the tag 105 imitates a gun, so the attribute “gun use” by the sub toy 100B is added to the name “medal monster” attached to the medal 100A, The sound including “Gun monster medal” is output.

  The usage example of the toy 10 shown in FIG. 10 uses both the medal 100A and the map 100C as an information holding medium. Similar to the tag 103 of the medal 100A, a plurality of tags 106 each including an antenna coil and an IC are embedded in the map 100C. The map 100C is a map of Japan in the illustrated example, and the tag 106 is provided for each prefecture, for example. Since the map 100 </ b> C has a flat shape, it is assumed that the toy 10 does not have a mounting portion when the medal 100 </ b> A is mounted. Therefore, the positional relationship between the toy 10 and the tag 106 of the map 100C is not constant.

  In the state where the tag 103 of the medal 100A is arranged on the upper lid 13 side of the toy 10 and any one tag 106 of the map 100C is arranged on the lower lid 14 side of the toy 10, the operation unit 36 of the toy 10 (FIG. 3). When an instruction to start communication is given by the switch operation of (see), the control unit 34 (see FIG. 3) of the toy 10 operates the communication unit 31 (see FIG. 3). The communication unit 31 exchanges signals between the antenna coil 21 and the tag 103 of the medal 100 </ b> A and the tag 106 of the map 100 </ b> C, and acquires electronic information held in the tag 103 and the tag 106. Specifically, the medal 100A and the tag 103 are arranged in a fixed positional relationship with respect to the first coil loop portion 211 adjacent to the toy 10 on the upper lid 13 side (arranged in the vicinity of the upper lid 13). The signal of the tag 103 is exchanged with the communication unit 31 by the first coil loop unit 211. Further, the secondary toy 100B and the tag 106 are not fixed in the positional relationship with the toy 10, but the second coil in the vicinity of the lower lid 14 whose magnetic field strength is increased by increasing the number of turns compared to the coil 211 on the upper lid 13 side. The loop unit 212 exchanges the signal of the tag 106 with the communication unit 31.

  Then, the control unit 34 reads the operation data corresponding to the combination of the electronic information of the tag 103 and the electronic information of the tag 106 acquired by the communication unit 31 from the storage unit 33 (see FIG. 3). Based on this, the operation unit 32 (see FIG. 3) is operated. Thereby, the operation unit 32 outputs an effect including at least one of sound and light. As an example of the production, the local phrase “Hokkaido” in the prefecture where the tag 106 of the map 100C is placed is added to the name “medal monster” of the character attached to the medal 100A. The sound that contains it is output.

  As described above, according to the toy 10 including the non-contact communication device 20, two sets of the antenna coil 21 and the signal processing circuit 23 disposed on the upper lid 13 side and the lower lid 14 side of the housing 11 are provided. Electronic information can be acquired from the information holding medium, respectively, and power and cost can be reduced. And by changing the production according to the combination of the two pieces of acquired electronic information, it is possible to diversify the production and enhance the interest of the toy.

  So far, the example in which the toy 10 acquires the electronic information held in the IC 102 of the information holding medium 100 has been described. However, the IC 102 may be configured to be rewritable and the toy 10 may be configured to write the electronic information to the IC 102. In this case, the control unit 34 of the toy 10 generates write information to be written in the IC 102 based on the electronic information acquired by the communication unit 31. And when two electronic information is acquired by the communication part 31, you may make it write information change according to the combination of two acquired electronic information.

  For example, in the usage example of the toy 10 shown in FIG. 9, the history of the sub-toy 100B used together with the medal 100A is written in the tag 103 of the medal 100A, and then an external device other than the toy 10 or the toy 10 (for example, a game housing or When the medal 100A is used in an entrance system or the like, a privilege can be generated according to the usage history of the medal 100A. Or, a character can be displayed according to the history, the winning rate of the game can be affected, or the medal 100A in which the history of communication with a specific secondary toy is written can be used as an entrance to the event venue. In addition, examples of electronic information to be written include the number of times played, character properties, game results, and the like.
