Description

Technical Field

[0001] Japanese application No. 2020-097951, application date June 4, 2020.

[0002] This invention relates to gaming media and gaming table systems for casinos. Background Technology

[0003] Previously, in casinos, game tokens and plaques were used to start games in table games. In recent years, an RFID technology has been developed that embeds information about the game medium within it. Such casino game media, within a flat substrate molded using resin inserts, contains an IC that stores game medium information such as game value, and a medium-side antenna with coils and capacitors. This casino game medium generates an induced electromotive force from the magnetic field produced by a reader mounted on the game table, and transmits the medium information to the reader using this electromotive force. For example, the frequency band for RFID radio waves is specified as the shortwave band (13.56MHz), and the medium-side antenna is designed so that its resonant frequency is the shortwave band frequency, thereby achieving stable communication.

[0004] However, such casino game media are typically stacked on a game table equipped with a reader by the organizers and participants of the table games. Therefore, the reader needs to accurately read the media information of each of the stacked casino game media. However, when reading from a stacked state, the resonant frequency of each media-side antenna sometimes decreases due to mutual inductance, making communication with the reader difficult.

[0005] Therefore, for example, in reference 1, the medium-side antenna is configured to include a main routing pattern arranged along a closed curve and multiple secondary routing patterns, each with a diameter smaller than that of the main routing pattern. This reduces the possibility of electromagnetic interference between the medium-side antennas of the stacked casino gaming media, enabling communication between the casino gaming media and the reader even when multiple casino gaming media are stacked.

[0008] Patent Document 1: U.S. Patent Application Publication No. 2015 / 0115042 Summary of the Invention

[0009] The technical problem that the invention aims to solve

[0010] However, it is known that the magnetic field generated by a reader extends with distance from the reader. Therefore, when stacking game media for casinos, the spacing between readers needs to be increased to prevent communication with other readers (so-called adjacent reading), which can limit the design of the game table where the readers are set up.

[0011] Therefore, the object of the present invention is to provide a gaming medium and gaming table system for casinos that can reduce adjacent readings without limiting the design of the gaming table.

[0012] Technical solutions adopted to solve technical problems

[0013] The gaming medium for casinos of the present invention is characterized by having: a medium-side antenna; a resistive element connected to the medium-side antenna; and an IC chip that stores medium information and outputs the medium information based on the induced electromotive force generated in the medium-side antenna.

[0014] Typically, in existing medium-side antennas, the LC circuit is designed to minimize losses and improve operating efficiency within a specified frequency band by maximizing the Q (Quality Factor) value, defined by 1 / R√(L / C). The gaming medium for casinos of this invention has a resistor element connected to the medium-side antenna, which is not normally present. Therefore, the Q value can be reduced by adjusting the resistance of the resistor element connected to the medium-side antenna without affecting the resonant frequency of the medium-side antenna. Furthermore, by intentionally reducing the Q value, the sensitivity can be desensitized to a level that prevents adjacent readings in practical gaming tables.

[0015] Alternatively, in the gaming medium for entertainment venues of the present invention, the medium-side antenna may be designed with a resonant frequency higher than a specified frequency band.

[0016] According to the above structure, by pre-setting the resonant frequency of the medium-side antenna to be higher than the specified frequency band, even if the resonant frequency of the stacked multiple medium-side antennas is reduced, the possibility of operating within the range of the gaming medium in the casino can be increased, without having to set the medium-side antenna to a complex structure like that of the prior art.

[0017] Alternatively, in the gaming medium for casinos of the present invention, the medium-side antenna, the resistive element, and the IC chip may be disposed on a PCB (Printed Circuit Board), with the resistive element separated from the IC chip on the PCB and disposed outside the area of ​​the spiral pattern of the coil serving as the medium-side antenna.

[0018] According to the above structure, the resistor element is separate from the IC chip and is positioned outside the area forming the spiral pattern of the coil of the dielectric-side antenna. Therefore, when adjusting the resistor element to set a resistance value that prevents adjacent readings, the impact on the dielectric-side antenna and IC chip, whose resonant frequency and other parameters have already been set and configured, can be reduced. As a result, designs involving changes to the resistor element can be easily implemented, as the resistance value only needs to be set in the final stage.

[0019] Alternatively, in the gaming medium for casinos of the present invention, the resistance value of the resistive element may be variable.

[0020] Based on the above structure, it becomes easy to explore the resistance values ​​of resistive elements that will not be read adjacently, matching the design of the reading side such as a game table.

[0021] Furthermore, the game table system of the present invention includes a game table for reading media information contained in a casino game medium, characterized in that the casino game medium has: a media-side antenna; a resistive element connected to the media-side antenna; and an IC chip that stores the media information and outputs the media information based on the induced electromotive force generated in the media-side antenna. The game table has a reader / writer disposed below each of a plurality of configuration areas in which the casino game medium is configured, and the reader / writer outputs an oscillation signal at a frequency contained in the specified frequency band.

[0022] Based on the above structure, the gaming medium for casinos of the present invention is designed such that the resonant frequency of the medium-side antenna is higher than a specified frequency band, and a resistor element, which is not normally provided, is connected to the medium-side antenna. Therefore, the Q value can be reduced by adjusting the resistance value of the resistor element connected to the medium-side antenna without affecting the resonant frequency of the medium-side antenna. Furthermore, by intentionally reducing the Q value, the sensitivity can be desensitized, thus adjusting the gaming medium in a practical gaming table, where readers are stacked on top of each other, to a level where adjacent readings are not possible.

[0023] Alternatively, in the game table system of the present invention, the resistance value of the resistive element may be set to a value such that each IC chip of a predetermined number of casino game media stacked on a reader in the game table will not be driven by a magnetic field based on the oscillation signal output by a reader adjacent to the reader.

[0024] Typically, existing game tables must design the readers separately to prevent adjacent readings of the gaming media. However, with the structure described above, in game tables actually using gaming media, the resistance value can be adjusted to prevent adjacent readings. As a result, the gaming media does not restrict the design of the game table, allowing for greater design freedom.

[0025] Alternatively, in the game table system of the present invention, the dielectric-side antenna may be designed with a resonant frequency higher than a specified frequency band.

[0026] According to the above structure, by pre-setting the resonant frequency of the medium-side antenna to be higher than the specified frequency band, even if the resonant frequency of the stacked multiple medium-side antennas is reduced, the possibility of operating within the range of the gaming medium in the casino can be increased, without having to set the medium-side antenna to a complex structure like that of the prior art.

[0032] Figure 6 This is an explanatory diagram showing a modified example of the structure of a gaming medium used in casinos. Detailed Implementation

[0033] The present invention will now be described with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the casino game medium 100 of this embodiment has a PCB (Printed Circuit Board) 11 and a housing 12 that houses the PCB 11 and forms the shape of the casino game medium 100.

[0035] As a type (attribute) of gaming medium 100 for casinos, there are game coins, badges, etc., with game value expressed as electronic data or game points, and a structure that allows the game value to be read from the outside. Furthermore, the term "external form" refers to a form that can be identified from the outside, such as color, pattern, text, image, and shape. In this embodiment, casino game coins are exemplified as gaming mediums for casinos, but the invention is not limited to this; any gaming medium used in a casino is not limited to this.

[0036] PCB 11 includes a dielectric-side antenna 110, a resistor element 111, and an IC chip 112. The resistor element 111 and the IC chip 112 are soldered onto a PWB (Printed Wiring Board) with a pre-applied wiring pattern for the dielectric-side antenna 110 to form PCB 11. The dielectric-side antenna 110 is formed in a spiral pattern, with the resistor element 111 and the IC chip 112 connected in series between its two ends. The gaming medium 100 for casinos is formed by insert molding in a manner that involves coating resin around such PCB 11. Furthermore, in this embodiment, a single spiral pattern is used as the wiring pattern for the dielectric-side antenna 110, but it is not limited to this.

[0037] In this embodiment, the casino gaming medium 100 is an RFID tag used in a passive shortwave band (13.56MHz), but the method and frequency band are not limited to this. The resonant frequency of the medium-side antenna 110 is set higher than this shortwave band (13.56MHz). The set value of the resonant frequency of the medium-side antenna 110 varies depending on the thickness of the housing 12 of the casino gaming medium 100 and the desired number of layers of the casino gaming medium 100. That is, for each number from 1 to a desired specific number of layers (e.g., 9), it is tested whether it can be read using a reader oscillating in a specified frequency band. Furthermore, the resonant frequency that is successfully read in all cases is applied to the resonant frequency of the medium-side antenna 110. The method of applying the resonant frequency can be a known method.

[0038] Resistor 111 is a general-purpose electronic component used to obtain a constant resistance value and reduce the Q value. In this embodiment, resistor 111 is connected in series with dielectric-side antenna 110. The higher the resistance value, the lower the Q value, but this is not a limitation. For example, resistor 111 can also be connected in parallel with dielectric-side antenna 110. In this case, the lower the resistance value, the lower the Q value.

[0039] IC chip 112 is a general-purpose electronic module, and its function is not particularly limited. For example, IC chip 112 may also have a storage section capable of storing various data such as individual information (ID), owner, and circulation history of the casino game medium 100. That is, the storage section (storage area) of IC chip 112 stores various data such as the game value data of the casino game medium in a manner that can be transmitted between it and an external server.

[0040] Thus, the gaming medium 100 for the casino has a medium-side antenna 110, a resistive element 111 connected to the medium-side antenna 110, and an IC chip 112 that stores medium information and outputs medium information based on the induced electromotive force generated in the medium-side antenna 110.

[0041] Based on the above structure, the dielectric-side antenna 110 is designed with a resonant frequency higher than the specified frequency band, and a resistor element 111, which is not normally provided, is connected to the dielectric-side antenna 110. Therefore, the Q value can be reduced by adjusting the resistance value of the resistor element 111 connected to the dielectric-side antenna 110 without affecting the resonant frequency of the dielectric-side antenna 110. Furthermore, by intentionally reducing the Q value, the sensitivity can be made less sensitive, adjusting to a level where adjacent readings are not possible in practical gaming tables.

[0042] Furthermore, the dielectric-side antenna 110 is designed with a resonant frequency higher than the specified frequency band. Thus, by pre-setting the resonant frequency of the dielectric-side antenna 110 to be higher than the specified frequency band, even if the resonant frequency of the stacked multiple dielectric-side antennas 110 is reduced, the possibility of operating within the range of the gaming medium 100 for the casino can be increased, without having to set the dielectric-side antenna 110 in a complex structure like that of the prior art.

[0043] In addition, such as Figure 1 As shown, on PCB 11, resistor 111 is positioned separately from IC chip 112. Furthermore, resistor 111 is located outside the area of ​​the spiral pattern of the coil serving as the dielectric-side antenna 110. Therefore, when adjusting resistor 111 to set a resistance value that prevents adjacent readings, the impact on the dielectric-side antenna 110 and IC chip 112, whose resonant frequencies and other configurations have already been set and determined, can be reduced. Consequently, designs involving changes to resistor 111 can be easily implemented, as the resistance value of resistor 111 only needs to be set in the final stage.

[0044] Next, the game table system 1, which has the ability to read the media information contained in the game table 2 of the casino game medium 100, will be described.

[0045] like Figure 2As shown, the game table system 1 is configured such that when a participant places the casino game medium 100 on the game table 2, it can read the medium information stored in the IC chip 112 of the casino game medium 100 placed on the game table 2. A detachable game board (not shown) is provided on the game table 2. The game board includes: a placement area for participants to place the casino game medium 100, an organizer area for the organizer to place the casino game medium 100 held by the organizer, and a result area for providing the game results (not shown). Furthermore, below the game board, five antenna modules 220 (antenna modules 221, 222, 223, 224, 225), antenna 226, and antenna 227, serving as readers for reading the casino game medium 100 placed in each of these areas, are embedded at positions corresponding to each area. Although not shown in the figure, antennas 2201-2205, antenna 226, and antenna 227 are connected to the control unit via a coupler board.

[0046] For example, five antenna modules 220 are configured as units having multiple antennas for reading the game participant areas 2100 of each configuration area 211, 212, 213, 214, 215. Antenna modules 221, 222, 223, 224, 225 are all configured identically, but are not limited thereto.

[0047] Specifically, such as Figure 3 As shown, the antenna module 220 has a generally rectangular parallelepiped shape. The housing 230 of the antenna module 220 is composed of a main body 231 and a cover 232. By aligning the cover 232 with the open upper surface of the main body 231, the housing 230 of the antenna module 220 with an internal space is formed.

[0048] In this embodiment, the antenna module 220, within the housing 230, has antennas 2201, 2202, 2203, 2204, and 2205, each for reading the casino game medium 100 configured in each area, according to the needs of each game participant. Antennas 2201, 2202, 2203, 2204, and 2205 output oscillation signals of a predetermined frequency band via power supplied from the antenna module 220, and the resulting electromagnetic induction induces an electromotive force (EMF) in the medium-side antenna 110 of the configured casino game medium 100. Then, the casino game medium 100, through its induced EMF, drives the IC chip 112 to send the stored medium information to the corresponding antenna.

[0049] like Figure 4As shown, antennas 2203, 2204, and 2205, which read the configuration areas of each game participant, are close together. For example, when antenna 2203 is driven, the resulting magnetic field Z extends upwards. Therefore, it is possible to affect the dielectric-side antenna 110 of the casino game medium 100, which is stacked on antenna 2204, generating an induced electromotive force to the extent of driving IC chip 112. Thus, in the casino game medium 100 of this embodiment, the sensitivity to magnetic field Z is reduced by connecting the resistive element 111 to the dielectric-side antenna 110 to lower the Q value.

[0050] The resistance value of the resistive element 111 installed in the gaming medium 100 for casinos is determined through trial use in a gaming table system 1 of the gaming medium 100 for actual application. That is, the resistive element 111 installed in the gaming medium 100 for casinos is set as a variable resistor, such as... Figure 4 As shown, a desired number of casino game media 100 are stacked on a specified antenna (e.g., antenna 2204). This number is preferably at least the number of casino game media 100 that the antenna module 220 can read. Then, the antenna adjacent to the antenna on which the casino game media 100 is configured (e.g., antenna 2203) is driven to change the resistance value of the resistive element 111, and the resistive element with the resistance value that is not read by any of the stacked casino game media 100 is found and applied during manufacturing. In this way, the resistive element 111 provided on the casino game media 100 is a variable resistor whose resistance value can be changed, thereby matching the design of the reading side such as a game table, and making it easy to explore the resistance values ​​of resistive elements that are not read adjacently.

[0051] In this embodiment, such as Figure 5 As shown, the game table system 1 has an organizer display 4 for organizer confirmation, on which the media information of the casino game medium 100 read by each antenna 2201, 2202, 2203, 2204, 2205 is displayed.

[0052] Specifically, the organizer display 4 displays five display areas 421, 422, 423, 424, and 425 corresponding to each of the antenna modules 221, 222, 223, 224, and 225. Specifically, display areas 420 (display areas 421, 422, 423, 424, and 425) each have a first display area 4211, a second display area 4212, a third display area 4213, a fourth display area 4214, and a fifth display area 4215. The first display area 4211 displays the total value of the game worth of the casino game medium 100 configured on antenna 2201. The second display area 4212 displays the total value of the game worth of the casino game medium 100 configured on antenna 2202. The third display area 4213 displays the total value of the game worth of the casino game medium 100 configured on antenna 2203. The fourth display area 4214 displays the total value of the game on the casino game medium 100 mounted on the antenna 2204. The fifth display area 4215 displays the total value of the game on the casino game medium 100 mounted on the antenna 2205.

[0053] Therefore, during the trial phase of the resonant frequency and resistance value of the gaming medium 100 for the casino, the desired number of gaming mediums 100 for the casino are stacked on the antenna 2204. With all antennas 2201, 2202, 2203, 2204, and 2205 driven, the state of all gaming mediums 100 for the casino is read only on the antennas configured with gaming mediums 100 for the casino.

[0054] For example, in Figure 5 In the example, when only a total of 300 game values ​​of casino game media 100 are stacked on antenna 2204, a portion (100 game values) of the casino game media 100 is read by antenna 2203. Therefore, it is necessary to adjust the resistance value of the resistive element to reduce the Q value of the casino game media 100 so that it is not read by antenna 2203.

[0055] Additionally, although not shown in the figure, in cases where none of the casino game media 100 are read by the antenna 2204, it is necessary to adjust the number of turns of the coil, etc., within a range that can be read even when there is only one casino game media 100, in order to increase the resonant frequency of the medium-side antenna 111 of the casino game media 100.

[0056] Thus, the resistance value of the resistor element 111 is set to a value such that the IC chips 112 of a predetermined number of casino game media 100 stacked on the antenna 2204 on the game table 2 will not be driven by the magnetic field of the oscillation signal output by the antenna 2203 adjacent to the antenna 2204.

[0057] Typically, existing game tables require separate reader / writer designs to prevent adjacent readings of the casino game medium 100. However, based on the structure described above, in the game table 2 where the casino game medium 100 is actually used, the resistance value can be adjusted to prevent adjacent readings. As a result, the casino game medium 100 does not restrict the design of the game table 2, allowing for greater design freedom.

[0058] The embodiments of the present invention have been described above, but these are merely illustrative examples and are not intended to limit the invention in any particular way. The specific structure of each device, etc., can be appropriately modified. Furthermore, the effects described in the embodiments of the present invention are merely examples of the best effects produced by the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention.

[0059] For example, in the above embodiments, the application of the casino gaming medium of the present invention to casino game coins was illustrated, but it is not limited thereto. Specifically, a variation of applying the casino gaming medium to badges will be described.

[0060] like Figure 6 As shown, similar to the embodiment described above, the badge (casino game medium) 100A has a PCB 11A and a housing 12A that internally houses the PCB 11A and forms the shape of the casino game medium 100A. The PCB 11A has a dielectric-side antenna 110A, a resistor element 111A, and an IC chip 112A. The resistor element 111A and the IC chip 112A are soldered onto a PWB with a pre-applied wiring pattern for the dielectric-side antenna 110A to form the PCB 11A. The dielectric-side antenna 110A is formed in a spiral pattern, with the resistor element 111A and the IC chip 112A connected in series between its two ends. The casino game medium 100A is insert-molded by coating resin around the PCB 11A, thereby forming a rectangular flat plate shape.

[0061] Furthermore, the number of turns of the spiral pattern of the dielectric-side antenna 110A is set to be greater than that of the casino coin mentioned above. Normally, the badge is formed with the same thickness as the casino coin, but since it is formed into a rectangular flat plate as described above, the area of ​​the surface representing the game value, etc., is set to be larger than that of the casino coin. Therefore, compared to the casino coin, since the area without the dielectric-side antenna 110A is wider, for example, a portion of the dielectric-side antenna 110A with the spiral pattern is more likely to escape the range of the magnetic field from the antenna module 220. Therefore, it is preferable to have a dielectric-side antenna 110A with a spiral pattern that has more turns than the casino coin, provided that the magnetic field affecting the dielectric-side antenna 110A is less than intended.

[0062] Furthermore, the detailed description above focuses on the feature portions to facilitate a clearer understanding of the invention. The invention is not limited to the embodiments described in the detailed description above, but can be applied to other embodiments, and its scope of application is diverse. Additionally, the terminology and grammar used in this specification are for the purpose of accurately describing the invention, and not for limiting its interpretation. Furthermore, it is believed that those skilled in the art can readily infer other structures, systems, methods, etc., included in the concept of the invention from the concept described in this specification. Therefore, the claims should be considered to include equivalent structures without departing from the technical spirit of the invention. Furthermore, the purpose of this abstract is to enable patent offices and general public authorities, or those skilled in the art who are not proficient in patent, legal, or professional terminology, to quickly determine the technical content and essence of this application through a simple investigation. Therefore, the abstract is not intended to limit the scope of the invention to be evaluated by the claims. Furthermore, in order to fully understand the purpose and unique effects of the invention, it is desirable to fully consider published documents, etc., in the interpretation.
