Fig. 1 and 2 show an example of a contactless communication device and a toy for explaining the embodiment of the present invention.

The toy 10 transmits and receives electronic information to and from an information holding medium holding the electronic information, and operates based on the electronic information acquired from the information holding medium.

Toy 10 includes housing 11. The housing 11 has: a case main body 12, for example, in a box shape; an upper cover (first surface) 13 covering an upper side (upper side in fig. 1) of the case main body 12; and a lower cover (second surface) 14 provided on the opposite side of the housing main body 12 from the upper cover 13. The upper surface of the upper cover 13 is covered with a cover 15. The upper cover 13, the lower cover 14, and the cover 15 are made of an electromagnetic wave transmitting material such as resin.

Toy 10 further includes a contactless communication device 20 that wirelessly communicates with the information holding medium. The contactless communication device 20 includes an antenna coil 21 and a circuit board 22, and is housed in the housing 11, wherein the circuit board 22 is mounted with a signal processing circuit that processes a signal transmitted to the information holding medium via the antenna coil 21.

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 cover 13, and the second coil loop portion 212 is disposed along the lower cover 14. The first coil loop portion 211 and the second coil loop portion 212 are disposed so as to sandwich the circuit board 22, which is an electromagnetic shield, provided on a straight line CL that passes through the first coil loop portion 211 and the second coil loop portion 212. In other words, the circuit board 22 as an electromagnetic shield is disposed on a straight line CL passing through the first coil loop portion 211 and the second coil loop portion 212 and between the first coil loop portion 211 and the second coil loop portion 212.

The first coil loop portion 211 and the second coil loop portion 212 are wound in the same direction around the straight line CL and are connected to the signal processing circuit 23 of the circuit substrate 22 in series with each other. In this example, the first coil loop portion 211 and the second coil loop portion 212 have the same loop shape and are formed in a substantially circular shape. In addition, in this example, the first coil loop portion 211 and the second coil loop portion 212 are disposed on the same axis, and a first plane on which the first coil loop portion 211 is disposed and a second plane on which the second coil loop portion 212 is disposed are disposed in parallel to each other.

Figure 3 shows a functional block diagram of 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 includes a contactless communication device 20, and transmits a signal to and from the information holding medium 100, and the contactless communication device 20 includes an antenna coil 21 and a signal processing circuit 23 mounted on a circuit board 22. 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 be capable of outputting a performance including at least one of sound and light. The storage unit 33 includes a ROM or the like, and stores a plurality of pieces of operation data for operating the operation unit 32 in association with the electronic information held in the information holding medium 100. The operating unit 32 may include a display body using a display medium or the like, an operating mechanism using a motor or the like, and the like.

The control unit 34 is configured to collectively control the communication unit 31, the operation unit 32, and the storage unit 33, mainly using a CPU. 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 operating unit 32, the storage unit 33, and the control unit 34. The operation unit 36 includes a power switch and a switch for instructing the control unit 34 to start communication with the communication unit 31.

An information holding medium 100 communicating 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 a command to start communication is given by a switching operation of the operation unit 36, an ac current is supplied to the antenna coil 21 of the toy 10, and an ac magnetic field is formed around the antenna coil 21. Induced electromotive force is generated in the antenna coil 101 of the information holding medium 100 placed in the ac magnetic field, and a current flows, and the IC 102 connected to the antenna coil 101 is driven. Then, a signal modulated based on the electronic information held in the IC 102 is transmitted from the antenna coil 101 of the information holding medium 100 to the antenna coil 21 of the toy 10 by the ac magnetic field, and the signal received by the antenna coil 21 is demodulated by the signal processing circuit 23, thereby extracting the electronic information.

The alternating-current magnetic field formed around the antenna coil 21 is synthesized from the alternating-current magnetic field formed by the first coil loop portion 211 and the alternating-current 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 in the same direction around the straight line CL and connected to the signal processing circuit 23 of the circuit substrate 22 in series with each other, so that the alternating-current magnetic field formed by the first coil loop portion 211 and the alternating-current magnetic field formed by the second coil loop portion 212 have the same phase and are mutually strengthened.

However, as shown in fig. 2, the circuit board 22 serving as an electromagnetic shield is disposed between the first coil loop portion 211 and the second coil loop portion 212, and eddy currents are generated in the conductor portion of the circuit board 22 such as the circuit pattern by magnetic fluxes of the ac magnetic field of the first coil loop portion 211 and the second coil loop portion 212 penetrating the circuit board 22. The eddy current generates a magnetic flux opposite to the magnetic flux penetrating the circuit board 22, and the intensity of the ac magnetic field formed around the antenna coil 21 can be reduced by the magnetic flux caused by the eddy current.

However, by disposing the first coil loop portion 211 and the second coil loop portion 212 so as to sandwich the circuit board 22, the magnetic field strength necessary for communication with the information holding medium 100 can be held on both the first coil loop portion 211 side and the second coil loop portion 212 side. If the antenna coil 21 is configured only by the first coil loop portion 211 (in the present embodiment, disposed along the upper cover 13) disposed near the upper cover 13 of the housing 11, the strength of the alternating magnetic field is significantly reduced on the lower cover 14 side of the housing 11, and communication cannot be performed.

Next, a preferred configuration example of the antenna coil 21 will be described with reference to fig. 4 to 6.

From the viewpoint of improving 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 to each other, and more preferably have the same loop shape as shown in fig. 2.

For example, in the example shown in fig. 4, the loop shape of the first coil loop portion 211 is substantially rectangular, and the loop shape of the second coil loop portion 212 is substantially circular, and if the loop shape of the first coil loop portion 211 and the loop shape of the second coil loop portion 212 are different from each other as described above, the non-overlapping region R is generated when the first coil loop portion 211 and the second coil loop portion 212 overlap each other. In the non-overlapping region R, the ac magnetic fields of the first coil loop portion 211 and the second coil loop portion 212 cancel each other out, and the strength of the ac magnetic field formed around the antenna coil 21, that is, the communication sensitivity, can be lowered. The non-overlap region R is not circularly symmetric with respect to the central axes of the first coil loop portion 211 and the second coil loop portion 212, and can cause a disturbance in the symmetry of the ac magnetic field formed around the antenna coil 21, that is, a disturbance in the communication sensitivity distribution.

By making the first coil loop portion 211 and the second coil loop portion 212 have similar loop shapes, even the same loop shape, the non-overlapping region R can be reduced to improve the magnetic field strength and symmetry of the alternating-current magnetic field formed around the antenna coil 21.

In addition, from the viewpoint of improving the magnetic field strength and symmetry of the alternating-current 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 portion 211 and the second coil loop portion 212 are shifted so as to be parallel to each other, and when the first coil loop portion 211 and the second coil loop portion 212 overlap each other, the non-overlapping region R is generated, which can cause the decrease in the intensity of the alternating-current magnetic field formed around the antenna coil 21 and the disturbance in the symmetry as described above. Even 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 intensity of the alternating magnetic field formed around the antenna coil 21 can be reduced and the symmetry can be disturbed.

By disposing the first coil loop portion 211 and the second coil loop portion 212 coaxially and in parallel with each other, the non-overlapping region R can be reduced, and the magnetic field strength and symmetry of the alternating-current magnetic field formed around the antenna coil 21 can be improved.

As shown in fig. 6, from the viewpoint of increasing the magnetic field strength of the ac magnetic field around the antenna coil 21, the circuit board 22 is preferably disposed inside the first coil loop portion 211 and the second coil loop portion 212 when viewed in the extending direction of a straight line CL (see fig. 2) passing through the first coil loop portion 211 and the second coil loop portion 212. By disposing the circuit board 22 inside the first coil loop portion 211 and the second coil loop portion 212, a part of the magnetic flux of the alternating magnetic field of the first coil loop portion 211 and the second coil loop portion 212 can pass by the circuit board 22 without penetrating the circuit board 22, and the magnetic field strength of the alternating magnetic field around the antenna coil 21 can be increased.

Next, an example of use of the toy 10 will be described with reference to fig. 7 to 10.

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

The information holding medium shown in fig. 7 is a badge 100A formed in a substantially disk shape, and a tag 103 formed by integrating an antenna coil 101 (see fig. 3) and an IC 102 (see fig. 3) is embedded in the badge 100A.

The upper cover 13 of the toy 10 is provided with an attachment portion 16 to which the emblem 100A is attached. 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 emblem 100A. The emblem 100A is guided by the pair of guide rails 161 and disposed at a predetermined position of the upper cover 13, and the tag 103 of the emblem 100A is disposed so that a positional relationship with respect to the first coil loop portion 211 disposed in the vicinity of the upper cover 13 (disposed along the upper cover 13 in the present embodiment) is fixed.

As shown in fig. 8 a, when a command to start communication is given by a switch operation of the operation unit 36 (see fig. 3) of the toy 10 in a state where the emblem 100A is attached to the attachment unit 16, the control unit 34 (see fig. 3) of the toy 10 operates the communication unit 31 (see fig. 3). The communication unit 31 transmits and receives signals between the antenna coil 21 and the tag 103 of the badge 100A to acquire electronic information held in the tag 103.

Then, the control unit 34 reads out the 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-out operation data. Thereby, a performance including at least one of sound and light is output from the operation unit 32. As an example of the presentation, a figure of a character different from badge to badge is marked on the badge 100A, and a sound including the name "badge monster" of the character is output.

In the example shown in fig. 8 (a), the tag 103 of the emblem 100A is disposed on the upper cover 13 side of the toy 10 disposed adjacent to the first coil loop portion 211 of the antenna coil 21, but as described above, the magnetic field strength necessary for communication is also maintained on the lower cover 14 side of the toy 10 disposed adjacent to the second coil loop portion 212, and therefore, even when the tag 103 of the emblem 100A is disposed on the lower cover 14 side as shown in fig. 8 (B), the communication unit 31 can transmit and receive signals between the antenna coil 21 and the tag 103 of the emblem 100A to acquire electronic information.

The tag 103 of the emblem 100A disposed on the upper cover 13 side by attaching the emblem 100A to the attachment portion 16 is disposed so that the positional relationship with respect to the first coil loop portion 211 provided adjacent to the upper cover 13 is fixed. On the other hand, it is also conceivable that, when the lower cover 14 is not provided with a mounting portion for mounting the emblem 100A and information holding media having various shapes other than the emblem 100A are disposed on the lower cover 14 side, the positional relationship between the information holding media disposed on the lower cover 14 side and the second coil loop portion 212 provided adjacent to the lower cover 14 is not fixed. Therefore, the magnetic field intensity on the lower cover 14 side is preferably higher than the magnetic field intensity on the upper cover 13 side, and the number of turns of the second coil loop portion 212 is preferably relatively large. In addition, it is also allowed to make the number of turns of the first coil loop portion 211 relatively small.

An example of use of the toy 10 shown in fig. 9 is a toy in which the badge 100A described above is used together with a sub-toy 100B imitating a gun as an information holding medium. Similarly to the tag 103 of the badge 100A, the tag 105 formed by integrating the antenna coil and the IC is embedded in the sub toy 100B.

When a command to start communication is given by a switch operation of the operation unit 36 (see fig. 3) of the toy 10 in a state where the tag 103 of the emblem 100A is disposed on the upper cover 13 side of the toy 10 and the tag 105 of the sub-toy 100B is disposed on the lower cover 14 side of the toy 10, the control unit 34 (see fig. 3) of the toy 10 operates the communication unit 31 (see fig. 3). The communication unit 31 transmits and receives signals between the antenna coil 21 and the tags 103 and 105 of the emblem 100A and the sub toy 100B to acquire electronic information held in the tags 103 and 105. Specifically, the badge 100A and the tag 103 are disposed so that the positional relationship with respect to a first coil loop portion 211 (disposed near the upper cover 13) provided adjacent to the upper cover 13 side of the toy 10 is fixed, and signals of the tag 103 are transmitted and received to and from the communication unit 31 through the first coil loop portion 211. The slave toy 100B and the tag 105 transmit and receive signals of the tag 105 to and from the communication unit 31 via the second coil loop part 212 (disposed near the lower cover 14) adjacent to the lower cover 14 side of the toy 10. In addition, by applying a known Anti-collision (Anti-collision) technique to the reading of the RFID (Radio frequency identification), it is possible to acquire electronic information from the tag 103 and the tag 105 without collision.

Then, the control unit 34 reads out operation data corresponding to a 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 operates the operation unit 32 (see fig. 3) based on the read-out operation data. Thereby, a performance including at least one of sound and light is output from the operation unit 32. As an example of the performance, since the sub toy 100B having the tag 105 imitates a gun, the attribute "gun for gun" based on the sub toy 100B is added to the name "badge monster" of the character marked on the badge 100A, and a sound including "badge monster with gun" is output.

An example of use of the toy 10 shown in fig. 10 is a toy in which the badge 100A described above is used together with a map 100C as an information holding medium. In the map 100C, similarly to the tag 103 of the badge 100A, a plurality of tags 106 formed by integrating an antenna coil and an IC are embedded. The map 100C is a japanese map in the illustrated example, and the tag 106 is set, for example, in prefecture. Since the map 100C is planar, it is assumed that the toy 10 is not provided with a mounting portion as in the case of mounting the emblem 100A. Thus, the positional relationship between the toy 10 and the tag 106 of the map 100C is not fixed.

When a command to start communication is given by a switch operation of the operation unit 36 (see fig. 3) of the toy 10 in a state where the tags 103 of the emblem 100A are disposed on the upper cover 13 side of the toy 10 and any one of the tags 106 of the map 100C is disposed on the lower cover 14 side of the toy 10, the control unit 34 (see fig. 3) of the toy 10 operates the communication unit 31 (see fig. 3). The communication unit 31 transmits and receives signals between the antenna coil 21 and the tags 103 of the badge 100A and the tags 106 of the map 100C, and acquires electronic information held in the tags 103 and the tags 106. Specifically, the badge 100A and the tag 103 are disposed so that the positional relationship with respect to the first coil loop portion 211 (disposed near the upper cover 13) adjacent to the upper cover 13 side of the toy 10 is fixed, and the signal of the tag 103 is transmitted and received to and from the communication unit 31 through the first coil loop portion 211. Although the positional relationship between the map 100C and the tag 106 and the toy 10 is not fixed, the signal of the tag 106 is transmitted and received to and from the communication unit 31 by the second coil loop portion 212 in the vicinity of the lower cover 14 as follows: the magnetic field strength of the second coil loop part 212 near the lower cover 14 is increased by making the number of turns of the second coil loop part 212 near the lower cover 14 larger than that of the first coil loop part 211 on the upper cover 13 side.

Then, the control unit 34 reads out operation data corresponding to a 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), and operates the operation unit 32 (see fig. 3) based on the read-out operation data. Thereby, a performance including at least one of sound and light is output from the operation unit 32. As an example of the presentation, a local place name of "hokkaido" in prefecture of prefecture in which the tag 106 is arranged of the map 100C is added to the name "monster of badge" of the character marked in the badge 100A, and a sound including "bikkaido monster of badge" is output, for example.

As described above, according to the toy 10 including the contactless communication device 20, by a set including the antenna coil 21 and the signal processing circuit 23, electronic information can be acquired from each of the two information holding media disposed on the upper cover 13 side and the lower cover 14 side of the housing 11, and power consumption and cost can be reduced. Further, by changing the performance according to the combination of the two pieces of electronic information acquired, the performance can be diversified, and the interest of the toy can be improved.

Although the toy 10 has been described as an example of acquiring the electronic information held in the IC 102 of the information holding medium 100, 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, and in this case, the control unit 34 of the toy 10 may generate the write information to be written to the IC 102 based on the electronic information acquired by the communication unit 31. When the communication unit 31 acquires two pieces of electronic information, the write information may be changed according to a combination of the two acquired pieces of electronic information.

For example, in the use example of the toy 10 shown in fig. 9, when the badge 100A is used in an external device (for example, a game housing, an admission system, or the like) other than the toy 10 or the toy 10 after the history of the sub-toy 100B used together with the badge 100A is written in the tag 103 of the badge 100A, privileges can be generated from the use history of the badge 100A. Alternatively, a character may be displayed based on the history, the winning rate of the game may be affected, or the badge 100A written with the history of communication with a specific slave toy may be used as an entrance pass of the event venue. In addition, the number of times played, the attribute of a character, the game result, and the like can be illustrated as the written electronic information.
