Description

Cross-reference to Related Applications

[0001] In this application, the benefit of Patent Application No. 2020-78604 filed in Japan on April 27, 2020 is claimed, and the content of the said application is hereby incorporated by reference.

Technical Field

[0002] The present invention relates to a double chip tray for accommodating gaming chips, a chip tray, and a game management system.

Background Art

[0003] In a casino, games are played using gaming chips (hereinafter simply referred to as "chips"). Players participate in the games by betting chips. A player who wins the game receives chip repayment from the dealer based on the game result and the bet amount, and a player who loses the game has the chips bet collected by the dealer.

[0004] On the game table where the game is played, there is provided a chip tray for storing chips owned by the dealer, that is, chips collected from the losing players and to be repaid to the winning players.

[0005] In a casino, in addition to cash chips that can be exchanged for cash by players, NN (Non-Negotiation) chips that can only be used for betting (however, when a player wins the game, they can receive repayment in cash chips) are used. NN chips have the limitation that they cannot be exchanged for cash, but players are given benefits when purchasing. The benefits are, for example, points that can be used in a hotel, or the ability to purchase at an exchange rate better than the equivalent. Due to such attributes, NN chips are also called promotional chips.

[0006] Furthermore, chips come in two shapes: disc-shaped and rectangular. Rectangular chips are sometimes called plaque chips (hereinafter, rectangular chips will be referred to as "plaque chips"). Generally, circular chips (hereinafter also called "round chips") are relatively inexpensive (for example, under $5,000), while rectangular chips are expensive (for example, over $10,000).

[0007] In games, round chips and plaque chips are used together. Therefore, the chip tray must be able to accommodate both round chips and plaque chips, which have different shapes.

[0008] Furthermore, the chip contains an RFID tag that stores information such as its value, attributes, and identification details. An RFID reader reads the information from the RFID tag within the chip, enabling various game management functions. [Prior art documents] [Patent Documents]

[0010] The present invention aims to provide a game management system that can manage games using RFID tags embedded in multiple types of chips with different shapes or sizes, even when these chips are housed in a chip tray, and a double chip tray or chip tray used therefor. [Means for solving the problem]

[0011] One embodiment of the present invention is a dual-chip tray for RFID that can accommodate two types of chips of different shapes and / or sizes. Specifically, the dual-chip tray is a dual-chip tray comprising an RFID chip reader capable of reading two types of chips of different shapes and / or sizes that have RFID tags embedded in them, an upper chip storage section capable of accommodating the chips, and a lower chip storage section capable of accommodating the chips, wherein the two types of chips are a disc-shaped chip and a rectangular plate-shaped chip, and both types of chips have at least one RFID tag associated with the value of the chip, the upper chip storage section accommodates at least the disc-shaped chips, and the lower chip storage section accommodates at least the rectangular plate-shaped chips, and the RFID chip reader is configured to read the RFID tags of the two types of chips, the disc-shaped chip and the rectangular plate-shaped chip, housed in the dual-chip tray and to determine their respective values.

[0012] This configuration allows for the reading of the RFID tags embedded in either chip, even when both round chips and plaque chips are housed in a dual chip tray, enabling the determination of the transaction amount.

[0013] In the above-described double chip tray, the disc-shaped chips may be placed vertically, and the rectangular plate-shaped chips may be placed vertically or horizontally. That is, in the above-described double chip tray, the disc-shaped chips may be stored vertically along a tube provided in the double chip tray, and the rectangular plate-shaped chips may be stored vertically or horizontally in the double chip tray, and the RFID chip reader may be able to read the RFID tags of the disc-shaped chips in a vertically placed state and the rectangular plate-shaped chips in a vertically placed or horizontally placed state.

[0014] This configuration allows for the reading of RFID tags even when vertically oriented round chips and vertically or horizontally oriented plaque chips are mixed together.

[0015] In the above-described dual-chip tray, the RFID chip reader may read the RFID tags of vertically and horizontally oriented chips, respectively. That is, in the above-described dual-chip tray, the RFID chip reader may be structured to be able to read the RFID tags embedded in the disc-shaped chip or the rectangular-shaped chip, regardless of whether the disc-shaped chip or the rectangular-shaped chip is placed vertically or horizontally within the dual-chip tray.

[0016] This configuration allows for reading RFID tags on chips that are housed in either a vertical or horizontal orientation.

[0017] In the above-described double chip tray, the RFID chip reader may read the RFID tag of the chip placed vertically in the upper section. That is, in the above-described double chip tray, the upper chip housing section may accommodate the disc-shaped chip or the rectangular plate-shaped chip in a state where it is placed vertically along the tube, and the RFID chip reader may be able to read the RFID tag of the disc-shaped chip or the rectangular plate-shaped chip placed vertically in the upper chip housing section.

[0018] This configuration allows for reading the RFID tags on chips that are vertically positioned on the upper level.

[0019] In the above-described double chip tray, the RFID chip reader may read the RFID tags of chips placed vertically and horizontally in the lower section, respectively. That is, in the above-described double chip tray, the lower chip storage section may be capable of accommodating the disc-shaped chips or rectangular plate-shaped chips vertically and horizontally, and the RFID chip reader may be capable of reading the RFID tags of the disc-shaped chips or rectangular plate-shaped chips placed vertically and horizontally in the lower chip storage section.

[0020] This configuration allows for reading RFID tags on chips that are placed vertically or horizontally in the lower section.

[0021] In the above double chip tray, the RFID chip reader may read the RFID tags of the chips vertically and horizontally placed in the upper layer respectively. That is, in the above double chip tray, the RFID chip reader may also be able to read the RFID tags of the disc-shaped chip or the rectangular plate-shaped chip housed horizontally in the upper chip housing portion.

[0022] With this configuration, the RFID tags of any chips vertically and horizontally placed in the upper layer can be read.

[0023] In the above double chip tray, there may be antennas in the upper layer and the lower layer respectively. That is, in the above double chip tray, the RFID chip reader includes a plurality of RFID antennas, and the plurality of RFID antennas may be arranged in the upper chip housing portion and the lower chip housing portion respectively.

[0024] Thereby, the RFID tags respectively built in the upper chip and the lower chip can be read by different RFID antennas respectively.

[0025] In the above double chip tray, a plurality of RFID may be recognized as those of one chip. That is, in the above double chip tray, when the disc-shaped chip or the rectangular plate-shaped chip includes a plurality of RFID tags, the RFID chip reader may be able to recognize the plurality of RFID tags as being built in the same disc-shaped chip or rectangular plate-shaped chip.

[0026] With this configuration, one chip is not recognized repeatedly, and the number and amount of chips can be accurately grasped.

[0027] The above double-chip tray may be capable of grasping the total amounts of the disc-shaped chips and the rectangular plate-shaped chips respectively. That is, in the above double-chip tray, based on the reading of the RFID tag, it may be possible to grasp the total amounts of the disc-shaped chips and the rectangular plate-shaped chips accommodated in the double-chip tray respectively.

[0028] With this configuration, it is possible to grasp the amounts of the cash chips and the NN chips accommodated in the double-chip tray respectively.

[0029] In the above double-chip tray, the upper and lower trays may be movable by a connecting mechanism. That is, the above double-chip tray may further include a connecting mechanism that connects the upper chip accommodating portion and the lower chip accommodating portion, and moves the upper chip accommodating portion between a position covering the lower chip accommodating portion from above and a position shifted from the lower chip accommodating portion to open the upper surface of the lower chip accommodating portion.

[0030] With this configuration, the upper surface of the lower chip accommodating portion can be opened by the connecting mechanism, and chips can be moved between the upper chip accommodating portion and the lower chip accommodating portion.

[0031] In the above double-chip tray, it may be determined whether the whole chips in the double-chip tray are the same before and after the movement of the upper tray. That is, the above double-chip tray may further include a determination means for determining whether there is a change in the total sum of the information of the RFID tags accommodated in the double-chip tray before and after the movement when the upper chip accommodating portion is moved by the connecting mechanism.

[0032] In the above double-chip tray, the determination result may be displayed. That is, the above double-chip tray may further include a display device for displaying the determination result of the determination means.

[0033] This configuration allows for visual confirmation of whether the chips have moved correctly between the upper and lower chip housing sections.

[0034] One aspect of the present invention is a game management system that verifies whether NN chips have been properly collected. Specifically, the game management system comprises one of the above double chip trays, a win / loss result determination device that determines the win / loss result of each game on a gaming table, a table chip determination device capable of identifying the position, attributes, and amount of the chips placed on the gaming table, and a management control device capable of understanding the attributes and amounts of the chips in the chip tray and the chips on the gaming table based on the reading result of the RFID chip reader on the chip tray and the determination result of the table chip determination device, wherein the management control device is structured to determine, when the collection of the losing chips bet by each player in each game is completed, that the chips that were bet in that game and should be collected have been collected in the chip tray, based on the win / loss result determined by the win / loss result determination device, the reading result of the RFID chip reader, and the determination result of the table chip determination device.

[0035] This configuration allows for determining whether the chips bet by the losing player were properly collected.

[0036] In the above game management system, it is possible to verify whether the cash chips have been properly collected. That is, in the above game management system, the management control device may be structured to determine, when the collection of each player's lost chips in each game is complete, whether the chips that were bet in that game and should be collected have been collected into the chip tray, based on the win / loss result determined by the win / loss result determination device, the reading result from the RFID chip reader, and the determination result from the table chip determination device.

[0037] This configuration allows for determining whether the chips bet by the losing player were properly collected.

[0038] In the above-described game management system, it is possible to verify whether the chips have been paid correctly. That is, in the above-described game management system, the management control device may be configured to determine, when the redemption of each player's winning chips in each game is complete, that the redemption of the winning chips has been made using the chips contained in the chip tray, based on the win / loss result determined by the win / loss result determination device, the reading result of the RFID chip reader, and the determination result of the table chip determination device.

[0039] This configuration allows for determining whether the winning player's bets were correctly redeemed.

[0040] In the above game management system, it is possible to check whether the total amount in the chip tray after collection and payment is correct. That is, in the above game management system, the management control device may add or subtract the amount of chips to be collected and the amount of cash chips to be redeemed, based on the win / loss result determined by the win / loss result determination device and the determination result of the table chip determination device, from the total amount of chips in the chip tray before settlement of each game to calculate the expected total amount of chips in the chip tray after settlement, compare it with the actual total amount of chips in the chip tray after settlement, and determine whether there is a difference between the expected total amount and the actual total amount.

[0041] This configuration allows for verification of whether the settlement was carried out correctly.

[0042] A chip tray according to one aspect of the present invention is capable of accommodating two types of chips of different shapes and / or sizes, and can read RFID tags of chips in both vertical and horizontal orientations. That is, a chip tray according to one aspect of the present invention is a chip tray equipped with an RFID chip reader capable of reading two types of chips of different shapes and / or sizes that have built-in RFID tags, wherein the two types of chips are a disc-shaped chip and a rectangular plate-shaped chip, and each of the two types of chips has built-in RFID tags associated with at least the value of the chip, and the RFID chip reader is configured to read the RFID tags of the disc-shaped chip and the rectangular chip, which are the two types of chips, housed in the chip tray, and to determine their respective values, wherein the disc-shaped chip can be stored in a vertical orientation along a tube provided in the chip tray, and the rectangular plate-shaped chip can be stored in the chip tray in either a vertical or horizontal orientation, and the RFID chip reader is configured to read the RFID tags of the disc-shaped chip or the rectangular plate-shaped chip in both a vertical and horizontal orientation.

[0043] This configuration allows for the reading of the RFID tags embedded in either chip, even when both round chips and plaque chips are stored in the chip tray, to determine the amount. [Brief explanation of the drawing]

[Figure 10] Figure 10 is a cross-sectional view of another example of a chip tray according to an embodiment of the present invention. [Figure 11] Figure 11 shows a modified example of the chip according to an embodiment of the present invention. [Modes for carrying out the invention]

[0045] The substitute currency for games according to this invention will be described in detail below with reference to the drawings. The components in the following embodiments include those that can be easily imagined by a person skilled in the art or that are substantially the same.

[0046] Figure 1 shows the configuration of a game management system including a chip tray according to an embodiment of the present invention. The game management system 100 of this embodiment includes a game table 1 including a betting area, a card shoe 2 placed on the game table 1, a chip tray 3 incorporated into the game table 1, a camera 4 that photographs at least the betting area, and a management control device 5 connected to the card shoe 2, the chip tray 3, and the camera 4.

[0047] The game table 1 of this embodiment is a table for playing a card game. In this card game, the dealer manipulates the cards. The game table 1 of this embodiment is, in particular, a table for playing baccarat. The game table 1 has a betting area 11 for players to place their betting chips and a card placement area 12 for the dealer to place the playing cards (hereinafter simply referred to as "cards") drawn from the card shoe 2. The betting area 11 is provided at each of the multiple player positions provided on the game table 1.

[0048] Figure 2 shows an example of the back of a playing card according to an embodiment of the present invention. A playing card (hereinafter referred to as "card") 6 is a rectangle consisting of a long side and a short side, with a pattern on the front and the rank and suit indicated on the back. A code 61, which becomes visible when illuminated with a black light, is attached to the edge of the short side of the back. The code 61 represents the rank and suit of the card.

[0049] The chips used in this embodiment include round chips and plaque chips.

[0050] Figure 3 shows an example of a round chip according to an embodiment of the present invention. The round chip 7 has a disc shape, and numbers indicating its value are inscribed on both surfaces. In this embodiment, the round chip 7 is the same size regardless of its value. The round chip 7 has an RFID tag 71 embedded within it. The RFID tag 71 stores the attributes of the chip (cash chip or NN chip), the value of the chip, and the identification information of the chip. In addition, the RFID tag 71 may also store rewritable owner history information (player ID, dealer ID, cage ID, etc.). Multiple RFID tags 71 may be embedded within a single round chip 7.

[0051] Each round chip 7 has a colored band running down the center of its thickness, forming a striped pattern of white-colored-white along its thickness. The color of the band on the side corresponds to the price of the round chip 7. Therefore, the price of a round chip 7 can be determined simply by observing its side, based on the color of the band. In particular, even when round chips 7 are stacked and the prices indicated on the surface cannot be seen, the price of each stacked round chip 7 can be determined by the color of the band on its side. Note that information other than the price may be represented by patterns on the side of the round chip 7. Alternatively, a code indicating the price or other information may be inscribed on the side of the round chip 7.

[0052] Figure 4 shows an example of a plaque chip according to an embodiment of the present invention. The plaque chip 8 is a rectangular plate shape or other shape that is larger than the round chip 7. In the example in Figure 4, the plaque chip 8 is a rectangular plate shape. The plaque chip 8 also has an RFID tag 81 embedded in it. The RFID tag 81 stores the attributes of the plaque chip (cash chip or NN chip), the value of the plaque chip, and the identification information of the plaque chip. The RFID tag 81 may also store rewritable owner history information. Note that a single plaque chip 8 may have multiple RFID tags 81 embedded in it.

[0053] Similar to the round chips 7, the sides of the plaque chips 8 are also marked with bands of different colors according to their size, forming a white-colored-white striped pattern in the thickness direction, allowing the size of the plaque chip 8 to be determined based on the pattern on its side.

[0054] Returning to Figure 1, inside the betting area 11 of the game table 1, a table chip reader 13 is installed as a table chip detection device to read the RFID tags 71 and 81 embedded in the round chips 7 and plaque chips 8, respectively. This table chip reader 13 is equipped with an antenna provided for each betting area 11. As a result, the table chip reader 13 can read the RFID tags 71 and 81 separately for each betting area 11.

[0055] The table chip reader 13 can simultaneously read the RFID tags 71 and 81 of multiple chips placed in the corresponding betting area 11. As described above, the value of the chip is stored in the RFID tags 71 and 81, so by reading the RFID tags 71 and 81 with the table chip reader 11, the total amount of chips bet in each betting area 11, i.e., the bet amount for each betting area 11, can be determined. The table chip reader 13 transmits the information read from the RFID tags 71 and 81 of the chips placed in each betting area 11 to the management control device 5.

[0056] The card shoe 2 holds shuffled cards 6 from multiple decks. The dealer can draw cards 6 one at a time from the card shoe 2. The card shoe 2 is equipped with a code reader 21 that reads the code 61 printed on the back of each card 6 as soon as it is drawn by the dealer.

[0057] In baccarat, the game outcome (i.e., which player won in which betting area) is determined solely by the rank of the multiple cards drawn sequentially by the dealer from card shoe 2. Therefore, card shoe 2 can determine the game outcome by reading the codes of the drawn cards. The game outcome (winning combinations) are Player, Banker, or Tie, in addition to Player Pair, Banker Pair, and other special winning combinations set by the casino. Each winning combination has a payout rate set according to its probability of occurrence.

[0058] Game table 1 has betting areas 11 corresponding to the above game results (winning methods) for each player position. Specifically, game table 1 has betting areas for each player position: player area 11p, banker area 11b, tie area 11t, and betting area 11 corresponding to special winning methods is provided as side betting area 11s.

[0059] The card shoe 2 stores the rank and order of at least the cards read during each game to determine the game result. The card shoe 2 includes a monitor 21, a lamp group 22 consisting of multiple lamps of different colors, and an operation button group 23 consisting of multiple buttons. The card shoe 2 displays the game result on the monitor 21 when the dealer operates the button group 23. The card shoe 2 illuminates lamps of different colors depending on the end and start of the game. The card shoe 2 transmits the rank (and suit) information of the read cards 6 to the management control device 5.

[0060] The chip tray 3 is a double chip tray comprising an upper chip storage section 31 and a lower chip storage section 32. The upper chip storage section 31 comprises a round chip storage section 31a for storing round chips 7 and a plaque chip storage section 31b for storing plaque chips 8. The lower chip storage section 32 comprises a round chip storage section 32a for storing round chips 7 and a plaque chip storage section 32b for storing plaque chips 8. The upper chip storage section 31 further comprises a recovered chip storage section 31c for temporarily storing round chips 7 recovered from the betting area 11.

[0061] The chip tray 3 is equipped with a tray chip reader 33 for reading the RFID tags 71 of the round chips 7 and the RFID tags 81 of the plaque chips 8, which are housed in the upper chip housing section 31 and the lower chip housing section 32. The tray chip reader 33 transmits the information read from the RFID tags 71 and 81 to the management control device 5.

[0062] Camera 4 is mounted on a pole fixed to the game table 1 so as to photograph the betting area 11 of the game table 1 from an oblique angle above. Camera 4 takes continuous shots to generate time-series image data. The image data generated by camera 4 is transmitted to the management control device 5.

[0063] The management control device 5 is a computer, and its processor performs various information processing as described below by operating according to a computer program. In other words, in this embodiment, the characteristics of the operation or processing of the management control device 5 in the following description are characteristics of the computer program. Each function of the management control device 5 described below may be implemented by an independent computer program, or it may be implemented as a program module within a single computer program.

[0064] The control device 5 acquires information from the table chip reader 13 regarding the RFID tags 71 and 81 read by the table chip reader 13, acquires information on at least the rank of the cards 6 drawn sequentially from the card shoe 2, acquires information from the chip tray 3 regarding the RFID tags 71 and 81 read by the chip tray reader 33, and acquires image data generated by the camera 4 from the camera 4. Based on the information from the RFID tags 71 and 81 from the table chip reader 13, the control device 5 determines the bet amount for each betting area 11, and determines the game result based on the rank information of the cards 6 obtained sequentially. Alternatively, the game result may be determined in the card shoe 2 and acquired by the control device 5.

[0065] The control unit 5 determines the betting status, specifically how many chips are bet in each betting area 11 at each play position, based on information obtained from the table chip reader 13. Furthermore, the control unit 5 performs image recognition on the image data obtained from the camera 4 to recognize the round chips 7 and plaque chips 8 visible in the image data, and to recognize the betting area 11 where those chips are placed. In other words, the control unit 5 also determines the betting status, specifically how many chips are bet in each betting area 11 at each player position, by performing image recognition on the image data.

[0066] The control device 5 can recognize each chip even when the round chips 7 and plaque chips 8 are stacked on top of each other. Specifically, the control device 5 detects the stacks of round chips 7 and plaque chips 8, detects the center line of the side from the image of each stack, and determines the value of the chip based on the color of the center line.

[0067] The management control device 5 compares the betting status determined by the table chip reader 13 and RFID tags 71 and 81 with the betting status determined by image recognition of the image data from the camera 4 to determine whether any fraudulent chips without built-in RFID tags 71 and 81 have been placed.

[0068] The management control device 5 identifies the attributes of each chip contained in the chip tray 3 based on the information from the RFID tags 71 and 81 obtained from the chip tray reader 33, and calculates the total value of each attribute of all chips contained in the chip tray 3, the total value of the round chips 7, the total value of the plaque chips 8, and the total value of all chips contained in the chip tray 3.

[0069] The control device 5 determines, based on the game results and betting situation, which player positions should collect their bet chips, the amount to be collected, and which player positions should receive a payout, according to the rules of the baccarat game. For bets that are lost, the bet amount is collected, and for bets that are won, the player receives a payout based on the bet amount according to the predetermined payout rules (payout rate).

[0070] Before settling the chips (i.e., collecting and redeeming them), the control device 5 obtains the total amount of chips actually contained in the chip tray 3 (actual total before settlement) based on information from the chip tray 3. The control device 5 calculates the total amount of chips that should be in the chip tray 3 after collection and redemption (calculated total) by increasing the confirmed collection amount and decreasing the confirmed redemption amount from the actual total before settlement. After collection and redemption have been performed, the control device 5 obtains the total amount of chips actually contained in the chip tray 3 (actual total after settlement) based on information from the chip tray 3. The control device 5 verifies whether the settlement was performed correctly by comparing the calculated total and the actual total after settlement and determining whether they match. In other words, the control device 5 determines whether the actual total after settlement matches the calculated total calculated based on the betting situation, game results, and initial total.

[0071] If the calculated total amount and the actual total amount after settlement do not match, it means that the chips have not been collected and redeemed as calculated. Therefore, the control device 5 outputs an error signal and records information that identifies the game in which the discrepancy occurred (for example, the identification information of game table 1, the date and time of the game, the difference in the discrepancy, etc.). At this time, the image data obtained from camera 4 is also recorded along with the information that identifies the game. The error signal is output to at least card shoe 2. Upon receiving the error signal, card shoe 2 displays the details of the error on monitor 21 and lights up the corresponding lamp.

[0072] In other words, the control device 5 adds or subtracts the amount of plaque chips 8 to be collected, round chips 7 to be collected, and round chips 7 to be redeemed, based on the win / loss result determined by the card shoe 2 and the determination result of the table chip reader 13, from the total amount of chips in the chip tray 3 before settlement of each game to calculate the total amount of chips that should be in the chip tray 3 after settlement (calculated total amount), compares it with the actual total amount of chips in the chip tray 3 after settlement (actual total amount after settlement), and determines whether there is a difference between the calculated total amount and the actual total amount after settlement.

[0073] In a typical baccarat game, the bets of losing players are collected first, and then the winning players are redeemed. The control device 5 calculates the total amount after collection by adding the collected amount to the actual total amount before settlement once the collection is complete. It then obtains the total amount of chips actually contained in the chip tray 3 at the time of collection (actual total amount after collection). The control device 5 verifies whether the collection was performed correctly by comparing the calculated total amount after collection with the actual total amount after collection and determining whether they match.

[0074] The management control device 5 then calculates the total amount after redemption by subtracting the redemption amount from the actual total amount after collection. It then obtains the total amount of chips actually contained in the chip tray 3 at the time redemption is completed (actual total amount after redemption). The management control device 5 compares the calculated total amount after redemption with the actual total amount after redemption and determines whether they match, thereby verifying whether the redemption was carried out correctly. In this way, the management control device 5 verifies whether both collection and redemption were carried out correctly.

[0075] The management control device 5 compares the calculated total amount with the actual total amount for the chip tray 3 after settlement, the calculated total amount with the actual total amount for the chip tray 3 after collection, and the calculated total amount with the actual total amount for the chip tray 3 after redemption, each for each chip attribute and for round chips 7 and plaque chips 8, as well as without distinguishing between round chips 7 and plaque chips 8.

[0076] For example, the control device 5 calculates the plaque recovery amount from the betting status and game results of the plaque chips 8, and adds the calculated plaque recovery amount to the actual total amount of plaque chips 8 in the chip tray 3 before recovery to calculate the calculated total amount of plaque chips 8 in the chip tray 3 after recovery. Then, the control device 5 verifies whether the plaque chips 8 were recovered correctly by comparing the calculated total amount of plaque chips 8 after recovery with the actual total amount of plaque chips 8 in the chip tray 3 after recovery.

[0077] In other words, when the collection of each player's lost chips in each game is complete, the control device 5 determines, based on the game result determined by the card shoe 2, the reading result from the table chip reader 13, and the reading result from the chip tray reader 33, that the plaque chips 8 that were bet in that game and should be collected have been collected into the chip tray 3.

[0078] As mentioned above, NN chips are chips that cannot be exchanged for cash. Therefore, cash chips are paid out as compensation to players who win the game, but NN chips are not paid out. Consequently, the number of NN chips does not increase or decrease from the time collection is completed until the end of the compensation, that is, before and after compensation, while the number of cash chips decreases.

[0079] Therefore, the management control device 5 determines whether there has been an increase or decrease in NN chips from the chip tray 3, and whether the number of cash chips has decreased, before and after redemption. If the number of NN chips has increased or decreased before and after redemption, the management control device 5 outputs an error signal. Also, if the number of cash chips has not decreased before and after redemption, the management control device 5 outputs an error signal.

[0080] Furthermore, for example, the control device 5 calculates the amount of cash chips to be collected from the betting status and game results of the cash chips, and adds the calculated amount of cash chips to the actual total amount of cash chips in the chip tray 3 before collection to calculate the calculated total amount of cash chips in the chip tray 3 after collection. The control device 5 then verifies whether the cash chips were collected correctly by comparing the calculated total amount of cash chips after collection with the actual total amount of cash chips in the chip tray 3 after collection.

[0081] In other words, when the collection of each player's lost chips in each game is complete, the control device 5 determines, based on the game result determined by the card shoe 2, the reading result from the table chip reader 13, and the reading result from the chip tray reader 33, that the cash chips that were bet in that game and should be collected have been collected into the chip tray 3.

[0082] Furthermore, for example, the control device 5 calculates the cash chip redemption amount from the cash chip betting status and game results, and calculates the calculated total amount of cash chips in the chip tray after redemption by subtracting the calculated cash chip redemption amount from the actual total amount of cash chips in the chip tray 3 before redemption. The control device 5 then verifies whether the cash chip redemption was performed correctly by comparing the calculated total amount of cash chips after redemption with the actual total amount of cash chips in the chip tray after redemption.

[0083] In other words, when the redemption of winning chips wagered by each player in each game is complete, the management control device 5 determines, based on the win / loss result determined by the card shoe 2, the reading result from the table chip reader 13, and the reading result from the chip tray reader 33, that the redemption of winning chips has been made using the cash chips contained in the chip tray 3.

[0084] Furthermore, the management control device 5 has, or is connected to, a database that stores valid chip identification information. The authenticity of a chip may be determined by determining whether the chip identification information stored in the RFID tags 71 and 81, read from the table chip reader 13 and the chip tray reader 33, respectively, is stored in the database as valid chip identification information.

[0085] Figure 5 is a plan view of a chip tray according to an embodiment of the present invention, Figure 6 is a cross-sectional view of a chip tray according to an embodiment of the present invention, and Figure 7 is a plan view of a chip tray according to an embodiment of the present invention with the upper chip storage section open. As described above, the chip tray 3 is a double chip tray equipped with an upper chip storage section 31 and a lower chip storage section 32.

[0086] The upper chip storage section 31 includes a round chip storage section 31a for storing round chips 7 in rows according to type, a plaque chip storage section 31b for storing plaque chips 8, and a recovered chip storage section 31c for temporarily storing the recovered round chips 7.

[0087] The round chip storage section 31a of the upper chip storage section 31 has a semi-tubular shape that conforms to the shape of the round chips 7. The round chips 7 are stacked vertically along the tube and stored in the round chip storage section 31a. The plaque chip storage section 31b has a tray-shaped groove that conforms to the shape of the plaque chips 8. The plaque chips 8 are stacked vertically along the groove and stored in the plaque chip storage section 31b.

[0088] The chip collection section 31c has a semi-tubular shape that conforms to the shape of the round chips 7, and the collected round chips 7 are stored in a vertical stack along the tube. The tube of the chip collection section 31c has a slit that extends in the longitudinal direction, i.e., in the direction in which the collected round chips 7 are stacked. A camera is provided on the back side of the slit. The camera takes a picture of a portion of the side of the round chips 7 stored in the chip collection section 31c through the slit. The control device 5 determines the total value of the round chips 7 stored in the chip collection section 31c based on this camera image.

[0089] The round chip storage section 32a of the lower chip storage section 32 has a semi-tubular shape that conforms to the shape of the round chip 7. The round chips 7 are stored in the round chip storage section 32a by stacking them vertically along the tube. In this embodiment, the round chips 7 are stored in a case 321 in which three tubes are integrated, and this case 321 is stored in the round chip storage section 32a. The plaque chip storage section 31b has a width greater than or equal to the width of the plaque chip 8. The plaque chips 8 are stored in the plaque chip storage section 31b by stacking them horizontally.

[0090] The chip tray reader 33 is an RFID chip reader provided as an RFID antenna on the back surface of the upper chip housing section 31. The RFID antenna is formed on the back surface of the upper chip housing section 31 so as to spread out in a planar direction. The shape of the RFID antenna and the electromagnetic waves generated from the antenna are designed to be able to read the RFID tags 71 and 81 of all round chips 7 and plaque chips 8 that are stacked vertically in the upper chip housing section 31 as described above, and also to be able to read the RFID tags 71 of all round chips 7 that are stacked vertically in the lower chip housing section 32 and the RFID tags 81 of all plaque chips 8 that are stacked horizontally.

[0091] In other words, the chip tray reader 33 is structured to be able to read the RFID tags 71 and 81 embedded in the round chips 7 and plaque chips 8, regardless of whether the round chips 7 and plaque chips 8 are placed vertically or horizontally within the chip tray 3.

[0092] Furthermore, the plaque chip storage section 31b of the upper chip storage section 31 can also accommodate plaque chips 8 stacked in a flat position, and the chip tray reader 33 can also read the RFID tags 81 of plaque chips 8 that are stored in the upper chip storage section 31 in this flat position.

[0093] Furthermore, the lower chip storage section 32 does not have tubes for storing round chips 7 or grooves for storing plaque chips 8, allowing round chips 7 and plaque chips 8 to be stored in any orientation, either vertically or horizontally. The chip tray reader 33 is configured to read the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 stored in the lower chip storage section 32 in any orientation, either vertically or horizontally.

[0094] In this embodiment, one RFID antenna is installed on the back surface of the upper chip storage section 31 as the chip tray reader 33. This RFID antenna reads the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 stored in the upper chip storage section 31 and the lower chip storage section 32 in vertical and horizontal orientations, respectively. However, instead, multiple RFID readers 33 may be installed as the chip tray reader 33.

[0095] Figure 8 shows an example in which, in the upper chip housing section 31, an RFID antenna 331 for reading the RFID tag 71 of the round chip 7 and an RFID antenna 332 for reading the RFID tag 81 of the plaque chip 8 are provided as separate antennas.

[0096] Figure 9 shows an example in which an RFID antenna 333 for reading the RFID tags 71 and 81 of the round chip 7 and plaque chip 8 housed in the upper chip housing section 31 and an RFID antenna 334 for reading the RFID tags 71 and 81 of the round chip 7 and plaque chip 8 housed in the lower chip housing section 32 are provided as separate antennas.

[0097] Figure 10 also shows an example in which an RFID antenna 335 for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 housed in the upper chip housing section 31 and an RFID antenna 336 for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 housed in the lower chip housing section 32 are provided as separate antennas, and each RFID antenna 335 and 336 is arranged in the stacking direction of the vertically positioned chips.

[0098] Furthermore, separate antennas may be provided for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 that are stored vertically in the upper chip storage section 31, for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 that are stored horizontally in the upper chip storage section 31, for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 that are stored vertically in the lower chip storage section 32, and for reading the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 that are stored horizontally in the lower chip storage section 32.

[0099] Furthermore, separate RFID antennas may be provided for reading the RFID tags of chips housed in a horizontal position and for reading the RFID tags of chips housed in a vertical position.

[0100] When multiple RFID antennas are used as the chip tray reader 33, the management control device 5, which receives reading results from each of these multiple RFID antennas, may use the identification information of the chips read by each antenna to integrate the information of the chips that have been read multiple times by the multiple antennas and calculate the total value of the chips contained in the chip tray 3.

[0101] Furthermore, if multiple RFID tags 71 and 81 are embedded in the round chip 7 or plaque chip 8, the same identification information is stored in each of the RFID tags 71 and 81. The chip tray reader 33 will read all of the multiple RFID tags 71 and 81 embedded in a single chip. The management control device 5 integrates the information of the multiple RFID tags 71 and 81 that have the same identification information, recognizes them as the information of the RFID tags embedded in a single chip, and calculates the total value of the chips contained in the chip tray 3.

[0102] Furthermore, as described above, the RFID tags 71 and 81 store information about the value of the chip, as well as information about the attributes of the chip (cash chip, NN chip). The chip tray reader 33 reads this attribute information from the RFID tags 71 and 81 and transmits it to the management control device 5, associating it with the value information. Based on the reading results of the RFID tags 71 and 81, the management control device 5 calculates the total value for each attribute of the chips contained in the chip tray 33, and also calculates the total value of all chips without distinguishing between attributes.

[0103] As shown in Figure 7, a connecting mechanism is provided between the upper chip housing section 31 and the lower chip housing section 32. This connecting mechanism 34 allows the upper chip housing section 31 to move between a closed position where the upper chip housing section 31 covers the lower chip housing section 32 from above, and an open position (the state in Figure 7) where the upper chip housing section 31 is shifted away from the lower chip housing section 32, leaving the upper surface of the lower chip housing section 32 open.

[0104] The open position is above the closed position and forward (away from the dealer and closer to the player position). This allows the dealer to easily access the lower chip storage section 32. The connecting mechanism 34 employs a parallel guide structure. This allows the upper chip storage section 31 to move diagonally upward in an arc from the closed position to the open position while maintaining horizontality, and also to move diagonally downward in an arc from the open position to the closed position while maintaining horizontality, without disturbing the chips stored in the upper chip storage section 31 during these movements.

[0105] When the dealer is playing the game, that is, under normal circumstances, the upper chip storage section 31 is used in the closed position. When the dealer runs out of chips in the upper chip storage section 31, the dealer moves the upper chip storage section 31 from the closed position to the open position, opening the lower chip storage section 32, taking the necessary chips from the lower chip storage section 32, and replenishing the upper chip storage section 31. Also, if the upper chip storage section 31 has an excess of chips, the dealer moves the upper chip storage section 31 from the closed position to the open position, moving some of the chips from the upper chip storage section 31 to the lower chip storage section 32.

[0106] The chip tray 33 detects when the upper chip housing 31 moves from the closed position to the open position (open movement) and when the upper chip housing 31 moves from the open position to the closed position (close movement) using a sensor (not shown). When the sensor detects the upper chip housing 31 moving to the open position, the chip tray 33 transmits a signal to the control device 5 to notify it of the open movement (open movement detection signal). When the sensor detects the upper chip housing 31 moving to the closed position, the chip tray 33 transmits a signal to the control device 5 to notify it of the closed movement (close movement detection signal). The chip tray 33 may also transmit a signal to the control device 5 to notify it of an opening / closing movement (open / close movement detection signal) when it detects both opening and closing movements.

[0107] When the control device 5 receives an open movement detection signal and a closed movement detection signal, it determines accordingly whether the total value of all chips contained in the chip tray 3 has increased or decreased. Immediately before receiving the open movement detection signal, the control device 5 compares the total value of chips detected by the chip tray reader 33 (total value before opening) with the total value of chips detected by the chip tray reader 33 immediately after receiving the closed movement detection signal (total value after closing).

[0108] If only chips have been moved between the upper chip storage section 31 and the lower chip storage section 32, there should be no difference between the total amount before opening and the total amount after closing. If the total amount before opening and the total amount after closing do not match, it is possible that chips have been added from the pit, moved to the pit, or that chips have been added to or removed from the chip tray 3 through some fraudulent means.

[0109] If the total amount before opening and the total amount after closing do not match, the control device 5 records this fact along with the positive or negative difference, and outputs an error signal to the outside indicating the discrepancy and the difference, if necessary. The control device 5, or any other device that receives this report, compares this error signal with the record of chip exchanges between the pitch and the game table 1 to determine whether the discrepancy is due to an exchange between the pitch and the game table 1, or whether there was some kind of fraud. The error signal is output to at least the card shoe 2. Upon receiving the error signal, the card shoe 2 displays the details of the error on the monitor 21 and lights up the corresponding lamp.

[0110] Furthermore, when the chip tray reader 33 uses multiple RFID antennas to distinguish between chips housed in the upper chip housing 31 and chips housed in the lower chip housing 32, the management control device 5 determines whether the increase or decrease in the upper chip housing 31 matches the decrease or increase in the lower chip housing 32.

[0111] The total value of chips held in chip tray 3 increases or decreases due to settlement (collection and redemption) in games. Therefore, as described above, the management control device 5 compares the calculated total value with the actual total value after settlement of each game. Players can request the dealer to exchange chips between games. Also, as described above, NN chips cannot be exchanged for cash or cash chips. However, some casinos allow players to exchange their NN chips for cash chips held by the dealer at a predetermined exchange rate lower than equivalent.

[0112] Therefore, the management control device 5 determines whether the exchange between the NN chips and the cache chips was performed correctly according to the set exchange ratio. For example, if the exchange ratio from NN chips to cache chips is set to 0.8, and the dealer provides the player with NN chips worth 100 and the dealer provides the player with cache chips worth 80, the management control device 5 compares the reading results of the chip tray 3 before and after the exchange and determines whether an amount of cache chips equal to 0.8 times the amount of NN chips added to the chip tray 3 has been removed from the chip tray 3.

[0113] Furthermore, if the player is permitted to exchange cash chips for NN chips, the management control unit 5 determines whether such an exchange was performed correctly according to the set exchange ratio. For example, if the exchange ratio from cash chips to NN chips is set to 1.1, and the dealer provides the player with NN chips worth 110 in exchange for cash chips worth 100, the management control unit 5 compares the reading results of the chip tray 3 before and after the exchange and determines whether an amount of NN chips equal to 1.1 times the amount of cash chips added to the chip tray 3 has been removed from the chip tray 3.

[0114] If the management control device 5 determines that the exchange between the cash chip and the NN chip has not been performed correctly, it records this fact along with the positive or negative difference between the calculated total amount and the actual total amount, and outputs an error signal to the outside indicating the fraud and the difference, if necessary. The error signal is output to at least the card shoe 2. Upon receiving the error signal, the card shoe 2 displays the details of the error on the monitor 21 and lights up the corresponding lamp.

[0115] As described above, with the chip tray 3 and game management system including it of this embodiment, even when round chips 7 and plaque chips 8 of different sizes or shapes are stored together, or when vertically placed chips and horizontally placed chips are stored together, the RFID tags 71 and 81 embedded in them can be read by the chip tray reader 33, and various game management can be performed based on that.

[0116] Furthermore, since RFID tags 71 and 81 each store information about the attributes of the chips, the management control device 5 can determine the attributes (cash chips, NN chips) of the chips housed in the chip tray 3, perform game management for the round chips 7 and plaque chips 8 respectively, and perform game management based on the attributes of the round chips 7 and plaque chips 8.

[0117] In the above embodiment, the tip tray 3 was a double tip tray equipped with an upper tip storage section 31 and a lower tip storage section 32. However, the tip tray 3 is not limited to this, and may be a single-tier tip tray capable of accommodating round tips 7 and plaque tips 8.

[0118] This single-tier chip tray is equipped with a tray chip reader capable of reading two types of chips (round chips 7 and plaque chips 8) with embedded RFID tags of different shapes or sizes. The tray chip reader reads the RFID tags 71 and 81 of the round chips 7 and plaque chips 8 contained in the chip tray, and the management control device 5 determines their respective attributes and values.

[0119] This chip tray can store round chips 7 in a vertical position along a tube provided within the chip tray 3, and can also store plaque chips 8 in a vertical or horizontal position. Even with such a single-tier chip tray, the chip tray reader can read the RFID tags 71 and 81 of the vertically and horizontally positioned round chips 7 and plaque chips 8.

[0120] Figure 11 shows a modified example of a chip according to an embodiment of the present invention. In this modified example, insert members 72 are provided at predetermined intervals around the periphery of the round chip 7'. These insert members 72 can be observed from the side, as well as from the front and back surfaces. The color, shape, and / or number of the insert members 72 represent the attributes of the chip (whether it is an NN chip or a cache chip). Therefore, with this modified example of the round chip 7', the attributes of the chip can be determined from the side, the front, and the back surfaces. The center line of the side of the round chip 7' continuously encircles the side of the round chip 7 without being obstructed by the insert members 72. The insert members 72 are provided at least three or more locations (at equal angular intervals of 120 degrees or less) so that they can be observed from the side regardless of the rotation angle of the round chip 7' in the circumferential direction.

[0121] Similar insert members may also be provided on the plaque chip 8. In the case of the plaque chip 8, at least one insert member may be provided on each of the four sides. Alternatively, insert members may be provided on only two long sides or only two short sides. [Explanation of symbols]
