Description

[0001] Divisional application

[0002] This application is a divisional application of the Chinese patent application with the application date of September 15, 2020, application number 202010967353.4, and invention name "Game Table Reading System". Technical Field

[0003] The present application relates to a gaming table reading system for reading RFID tags from a gaming table used in table games. Background Art

[0004] A game table is used in a casino. On the game table, placement objects are drawn using lines or colors, and players place game coins on the placement objects drawn on the game table to place them in the placement objects. For example, on a card game table, multiple playing positions are set, and in each playing position, placement objects such as player, banker, and tie are drawn using lines or colors to distinguish them.

[0005] On the other hand, recently, in order to prevent cheating or mistakes of players and dealers, to grasp the deposit amount, repayment amount, and recovery amount and apply them to the operation of the casino, and to track the movement of game coins in the casino, RFID tags storing identification information of game coins (game coin ID) and other information are built into the game coins. In addition, multiple antennas for reading RFID tags are set at the game table, etc. The management control device obtains the information of the RFID tags read by the multiple antennas, and which antenna detects which RFID tag, thereby grasping where the game coins are located.

[0006] In order to grasp the movement of game coins on a game table, it is effective to more accurately determine the position of the game coins. For example, in order to achieve the above purpose at a higher level, it is effective not only to simply grasp that the game coins are located on a certain game table, but also to grasp which playing position the game coins are located at, and then to grasp which placement object the game coins are placed on. Summary of the invention

[0007] Technical problem to be solved by the invention

[0008] In order to grasp the more detailed position of the game coins on the game table, it is effective to use more reading antennas with narrow reading ranges. However, if such reading antennas are set close to each other, the following problems will arise: the RFID tags of game coins that exceed the expected reading range of each reading antenna or even the reading range of other reading antennas are responsible for reading.

[0009] Therefore, an object of the present application is to provide a gaming table reading system that reduces the problem of multiple reading antennas of a gaming table reading RFID tags that are within the reading range of other reading antennas.

[0010] Means for solving technical problems

[0011] A gaming table reading system according to one embodiment of the present application comprises: a gaming table having a plurality of reading areas, the plurality of reading areas including at least a plurality of placement areas for placing gaming coins with built-in RFID tags; a plurality of reading antennas correspondingly arranged in each of the plurality of reading areas for reading the RFID tags built into the gaming coins placed in the corresponding reading areas; a reading restriction antenna correspondingly arranged in each of the plurality of reading areas for restricting the RFID tags built into the gaming coins placed in the corresponding reading areas from being read by the reading antennas corresponding to other adjacent reading areas; a reading control device connected to the plurality of reading antennas for controlling the plurality of reading antennas; and a reading restriction control device connected to the plurality of reading restriction antennas for controlling the plurality of reading restriction antennas; the reading control device causes the plurality of reading antennas to read in sequence, the reading restriction control device having the following structure: synchronized with the reading control device, causing the plurality of reading restriction antennas corresponding to the following plurality of reading areas to be subjected to reading restrictions, the plurality of reading areas being the plurality of reading areas adjacent to the reading area corresponding to the reading antenna that is read by the reading control device.

[0012] According to this structure, by performing reading restrictions in multiple reading areas adjacent to the reading area where the reading antenna reads, and sequentially changing the reading area where the reading antenna reads, it is possible to appropriately read the RFID tag for each of these reading areas even when multiple reading areas are adjacent to each other and the reading areas are dense.

[0013] In the above-mentioned gaming table reading system, the reading control device may control the plurality of reading antennas so that the plurality of reading antennas corresponding to the plurality of adjacent reading areas do not read at the same time.

[0014] According to this configuration, since control is performed so that adjacent reading areas are not read at the same time, it is possible to more reliably perform individual reading of a plurality of reading areas.

[0015] In the above-mentioned gaming table reading system, the reading restriction control device may cause the reading restriction antenna within a predetermined distance from the reading antenna that is performing reading to perform reading restriction.

[0016] According to this configuration, reading can be restricted in a reading area that is not adjacent to the reading area being read but can be read by the reading antenna.

[0017] In the above-mentioned gaming table reading system, the reading control device may start the next reading by the reading antenna when a predetermined time has passed since the reading antenna that is performing reading stops reading new information.

[0018] According to this structure, even if there are multiple RFID tags in the reading area and reading takes time, or there are only a few RFID tags in the reading area, or there are no RFID tags in the reading area and reading is completed in a short time, incomplete reading can be prevented and reading can be performed with high time efficiency.

[0019] In the above-mentioned gaming table reading system, the reading control device may include a reading intensity setting unit, which sets the intensity of electromagnetic waves used for reading by the reading antenna, and the reading restriction control device may determine the reading restriction antenna for performing reading restriction based on the intensity set by the reading intensity setting unit.

[0020] According to this configuration, reading can be limited to a necessary range according to the intensity of the electromagnetic wave of the reading antenna.

[0021] In the above-mentioned gaming table reading system, the reading restriction control device may determine the reading restriction antenna to be used for the reading restriction according to the size of the area to be read by the reading control device.

[0022] According to this configuration, when reading is performed simultaneously by a plurality of reading antennas, for example, the reading limiting antenna for performing reading limitation can be different when reading is performed in a wide area and when reading is performed in a relatively narrow area.

[0023] In the above-mentioned gaming table reading system, the reading control device can cause some of the multiple reading antennas to read simultaneously, and the reading restriction control device can cause the reading restriction antenna located between the multiple reading antennas that read simultaneously to perform reading restriction.

[0024] According to this configuration, it is possible to avoid reading RFID tags in a reading area other than the reading area corresponding to the reading antenna, and simultaneously read a plurality of reading areas using a plurality of reading antennas.

[0025] In the above-mentioned gaming table reading system, the reading control device can enable another part of the plurality of reading antennas to read simultaneously after the part of the plurality of reading antennas have all completed reading.

[0026] According to this configuration, it is possible to prevent adjacent read areas from being read simultaneously.

[0027] The above-mentioned gaming table reading system may further include: a game status determination system that determines the progress status of the game, and the reading control device may cause the reading antenna selected according to the game progress status determined by the game status determination system to perform reading.

[0028] According to this configuration, a necessary read area can be read according to the progress of the game.

[0029] In the above-mentioned gaming table reading system, the reading restriction control device can control the reading restrictions of the plurality of reading restriction antennas so that the reading antennas and the reading restriction antennas corresponding to the same reading area do not perform reading and reading restrictions at the same time.

[0030] According to this configuration, it is possible to prevent the read limiting antenna from interfering with the reading of the read antenna corresponding to the same read area.

[0031] In the above-mentioned gaming table reading system, the reading antenna may be in a loop shape, and the reading control device may open the loop of the reading antenna in the reading area where no reading is performed.

[0032] In the above-mentioned gaming table reading system, the gaming table may be a card game table, and the plurality of reading areas may include a plurality of side placement areas, which are provided at each playing position and are arranged adjacent to each other.

[0033] According to this configuration, in a card game, it is possible to read information of an RFID tag embedded in a token placed in the side placement area.

[0034] In the above-mentioned gaming table reading system, the gaming table may have a plurality of playing positions, and the plurality of reading areas may be set at each of the playing positions.

[0035] According to this structure, the RFID tag can be read individually at each play position.

[0036] In the above-mentioned gaming table reading system, the plurality of reading areas may include a player area and a banker area which are disposed at each of the playing positions and are adjacent to each other.

[0037] According to this structure, the RFID tag can be read at each play position and at each placed object.

[0038] In the above-mentioned gaming table reading system, the player area and the banker area can be divided into a plurality of reading areas.

[0039] According to this configuration, even when different users place tokens in the same placement area, each stack of tokens can be read separately.

[0040] In the above-mentioned gaming table reading system, the RFID tag may be embedded in a membership card given to a user playing gaming at the gaming table, and the plurality of reading areas may include a card reading area where the membership card is placed.

[0041] According to this configuration, the membership card can be read at the gaming table.

[0042] In the above-mentioned gaming table reading system, the multiple reading areas may include a game coin tray area for the dealer to store the game coins, and when the reading control device enables the reading antenna corresponding to the game coin tray area to read, the reading restriction control device may enable the reading restriction antenna corresponding to the reading area outside the game coin tray area to perform reading restriction.

[0043] According to this configuration, even when the reading antenna corresponding to the medal tray area uses electromagnetic waves with relatively strong intensity, it is possible to prevent the RFID tag in the placement area from being read.

[0044] In the above-mentioned gaming table reading system, the multiple reading areas may include a pair area for reading the gaming coins paid by the dealer to the winner, and when the reading antenna corresponding to the pair area performs reading, the reading restriction control device may cause the reading restriction antenna corresponding to other reading areas around the pair area to perform reading restriction.

[0045] According to this configuration, when reading a sub-area, it is possible to prevent RFID tags in other surrounding reading areas from being read.

[0046] In the above-mentioned gaming table reading system, the multiple placement areas may include a player area and a dealer area set at each of the multiple playing positions, and the read restriction control device controls the multiple read restriction antennas so that when the read antenna corresponding to the player area of ​​a certain playing position performs reading, the read restriction antenna corresponding to the dealer area of ​​the playing position performs reading restriction, and when the read antenna corresponding to the dealer area of ​​a certain playing position performs reading, the read restriction antenna corresponding to the player area of ​​the playing position performs reading restriction.

[0047] According to this structure, the player area and the banker area of ​​the same play position can be read separately.

[0048] In the above-mentioned gaming table reading system, the plurality of mutually adjacent reading areas may be divided by one or two lines and may be adjacent to each other at a distance smaller than the size of the gaming coin.

[0049] The above-mentioned game table reading system can also include: a camera, which photographs the game coins placed in the reading area and generates an image; and an image recognition device, which analyzes the image generated by the camera to grasp the reading area where the game coins are placed, the type of game coins, and the number of game coins.

[0080] The following describes a gaming table reading system for reading RIFD tags on a gaming table. In the following embodiments, the gaming table is a card table for playing card games, but the present application is not limited to card tables and can be applied to any gaming table.

[0081] (First Embodiment)

[0082] Figure 1 1 is a diagram showing the structure of a gaming table reading system according to a first embodiment of the present application. The gaming table reading system 1 includes a gaming table 2 having a substantially elliptical shape. A player 3 is located on one side of the gaming table 2 ( Figure 1 The lower side of the game table 2 is provided with a coin tray 6 for placing the dealer's coins 5. Although the illustration is omitted for convenience of viewing the accompanying drawings, each of the placement areas 4a to 4e is divided into a player pair area, a banker pair area, a tie area, a player area, and a banker area.

[0083] As described above, the placement areas 4a to 4e of the gaming table 2 are divided into a player pair area, a banker pair area, a tie area, a player area, and a banker area. Figure 2 4a. Furthermore, each of the placement areas is provided with a reading antenna 71a to 75e (hereinafter, collectively referred to as "reading antenna 7") for reading the RFID tag built into the game coin 5. Specifically, the reading antenna 7 is respectively under the wool of the game table 2 and embedded in the position dividing the corresponding placement area 4. In addition, a reading antenna 8 is also provided in the game coin tray 6.

[0084] It should be noted that, hereinafter, each area provided with a reading antenna is sometimes referred to as a reading area. That is, the player pair area, the banker pair area, the tie area, the player area, the banker area, and the coin tray 6 are equivalent to the reading area respectively.

[0085] The reading antenna 7 and the reading antenna 8 are connected to the reading control device 9. Figure 1In the figure, only the dotted line representing the read antenna 71e and the line connecting it to the read control device 9 are shown. For the sake of easier viewing of the figure, the dotted lines representing the read antennas other than the read antenna 71e and the lines connecting them to the read control device 9 are omitted. However, the read antennas other than the read antenna 71e are also provided in each placement area 4 and are connected to the read control device 9 in the same manner as the read antenna 71e. The same is true in the following figures. The read control device 9 performs reading control for each read antenna separately.

[0086] In addition to the reading antennas 71a to 75e, read limiting antennas 101a to 105e (hereinafter collectively referred to as "read limiting antennas 10") are provided in each placement area 4a to 4e of the game table 2. The read limiting antennas 10 have the following function: the RFID tags built into the game coins 5 placed in the reading area corresponding to each antenna are limited to be read by the reading antennas 7 corresponding to other adjacent reading areas. Similar to the reading antennas 7, the read limiting antennas 10 are located under the fabric of the game table 2 and embedded in the position that divides the corresponding placement area 4. In addition, the game coin tray 6 is also provided with a read limiting antenna 11.

[0087] The read restriction antennas 101a to 105e and the read restriction antenna 11 are connected to the read restriction control device 12. The read restriction control device 12 performs read restriction control for each read restriction antenna.

[0088] The reading control device 9 enables the reading antenna 7 to read sequentially, and the reading restriction control device 12 synchronizes with the reading control device 9 to enable the reading restriction antenna 10 corresponding to the following reading area to perform reading restriction, wherein the reading area is a reading area adjacent to the reading area corresponding to the reading antenna 7 that the reading control device 9 enables to read.

[0089] use Figure 2 The specific reading process is described. For example, when reading in the tie area, the reading antenna 73a reads, and the reading restriction antenna 102a of the banker sub-area adjacent to the tie area and the reading restriction antenna 104a of the player area are read. In this way, the reading of each area is performed in sequence.

[0090] In addition, the placement area 4 includes the player area and the banker area, but these areas are not read at the same time. Figure 2 In the example, when the reading antenna 74a of the player area performs reading, the reading restriction control device 12 causes the reading restriction antenna 105a of the banker area to perform reading restriction. Similarly, when the reading antenna 75a of the banker area performs reading, the reading restriction control device 12 causes the reading restriction antenna 104a of the player area to perform reading restriction. It should be noted that although Figure 1In the example of FIG. 1 , the reading control device 9 and the reading limit control device 12 are separate devices, but the reading control device 9 and the reading limit control device 12 may be configured as one device. These devices may be devices for controlling an antenna substrate called an RFID reader.

[0091] According to this structure, the player area and the banker area existing in the same play position can be read accurately and separately.

[0092] According to the above structure, reading restrictions are performed in multiple reading areas adjacent to the reading area where the reading antenna 7 reads, and the reading area where the reading antenna 7 reads is changed sequentially, so that even if multiple reading areas are adjacent to each other and the reading areas are dense, the RFID tags can be properly read separately for each of these reading areas.

[0093] It should be noted that even in non-adjacent reading areas, the reading restriction antenna 10 within a predetermined distance from the reading antenna 7 that performs reading may be configured to perform reading restriction.

[0094] That is, for example, it can be configured as follows: Figure 2 When the banker area is read by the reading antenna 75a, not only the reading restriction antenna 104a of the player area adjacent to the banker area but also the reading restriction antenna 103a of the tie area is activated.

[0095] According to this configuration, even if it is not adjacent to the reading area being read, it is possible to restrict reading in the reading area that may be read by the reading antenna 7 that is performing reading.

[0096] Furthermore, the read restriction control device controls the read restrictions of the plurality of read restriction antennas so that the read antenna 7 and the read restriction antenna 10 corresponding to the same read area do not perform reading and read restriction at the same time.

[0097] It should be noted that, in the figure, the reading antenna 7 in the reading area is shown outside the reading limiting antenna 10, but it is not necessary to arrange it in this way, and the arrangement of each antenna can be any structure. The same applies to the following.

[0098] Furthermore, the division of the area within the placement area can be constructed as follows: Figure 3 As shown, the player pair area and the banker pair area are arranged horizontally.

[0099] In addition, the reading of the placement area does not necessarily have to be performed for each player pair area, banker pair area, tie area, player area, and banker area, and the entire placement area may be read.

[0100] In addition, further, a side placement area is provided at each play position as an area where players play games. Figure 2 For example, the player pair area and the banker pair area are equivalent to the side placement area. It can be configured to read according to each side placement area.

[0101] According to the above configuration, the RFID tag can be read individually at each play position and at each side placement area.

[0102] In a certain card game, as described above, a plurality of playing positions are provided in the gaming table 2, and a placement area 4 is provided for each playing position at a position corresponding to each playing position of the gaming table 2. In principle, one player plays the game at one playing position. However, when all the playing positions are full, there may be players (behind-the-scene players) who place coins in the placement area 4 assigned to the players who are sitting behind the players who are playing the game at the playing positions (the players sitting in the seats), and such placement is allowed depending on the casino or gaming table 2. Due to the behind-the-scene placement, a plurality of game coins 5 with different user IDs may be placed in the same placement area. The gaming table reading system of this example can read the game coins 5 separately even in such a case. In the following, using Figure 4 Provide explanation.

[0103] Figure 4 FIG. 1 is a diagram showing a modified example of the placement area in the first embodiment. Figure 2 In addition to the structure of the placement area shown in FIG. 1 , each area is further divided into a plurality of areas. The reading antenna 7 and the reading restriction antenna 10 are also respectively provided in each area.

[0104] According to the above structure, even if each placement object is placed in the play position, and even if different users (such as players placing behind) place the game tokens 5 in the same placement area, each stack of the game tokens 5 can be read separately.

[0105] It should be noted that in Figure 4 In the embodiment, the placement area of ​​each play position is divided into two areas, but it can also be a structure divided into three or more areas. In addition, the structure of the game table 2 is as follows Figure 2 As shown, for each playing position, a banker area, a player area, a tie area, a banker pair area, and a player pair area are each provided with one, but the reading antenna 7 and the reading limit antenna 10 are as shown in FIG. Figure 4 The structure shown may be a structure in which multiple ones are arranged in the same reading area.

[0106] Figure 5 1 is a diagram showing another modification of the placement area in the first embodiment. Figure 5In the example of FIG. 1 , a plurality of reading antennas 7 are provided in the dealer area, and a plurality of reading restriction antennas 10 are provided corresponding to each reading antenna 7. Thus, the game coins 83 can be read separately in the same placement object area. Thus, for example, even when there are multiple piles of game coins 83 in the same placement object as when placing behind, these piles can be read by the respective reading antennas 7, so that the multiple piles in the same placement object area can be read separately. The player who places it is identified for each pile, and through identification, the user ID can be associated with the information of the placed game coins or paid game coins for the main player (player at the table) and the player placing behind.

[0107] (Second Embodiment)

[0108] Figure 6 1 is a diagram showing the structure of the gaming table reading system used in the second embodiment. In the gaming table reading system 13, a player identification system is introduced based on the structure of the gaming table reading system 1 of the first embodiment. The player identification system includes a card authentication system formed by a membership card 14 and a card reading area 15. The membership card 14 is given to a user (member) who plays a game at the gaming table 2. An RFID tag is embedded in the membership card 14, and the membership card 14 is placed in the card reading area 15 to read the information of the membership card 14. The RFID tag of the membership card 14 stores identification information (user ID) for uniquely identifying the player.

[0109] According to this configuration, the membership card 14 can be read on the gaming table 2 .

[0110] It should be noted that in Figure 6 In the embodiment, the card reading area 15 is located at one place of the game table 2 , but it may be provided at a plurality of places of the game table 2 .

[0111] Furthermore, a card reading area 15 may be provided for each playing position on the game table 2. In addition, the placement area 4 of each playing position may also serve as the card reading area 15 of each playing position. In this case, the reading antenna 7 provided corresponding to the placement area 4 reads the RFID tag of the membership card 14.

[0112] According to this structure, since the member information stored in the member card 14 is read at the playing position, the member does not need to hand the member card 14 to the dealer, and the dealer does not need to operate the member card 14. The game table reading system 13 can know which member is sitting at which playing position.

[0113] It should be noted that the reading area described below also includes the card reading area 15 .

[0114] (Third Embodiment)

[0115] Figure 7 This is a diagram showing the structure of the gaming table reading system used in the third embodiment. In the gaming table reading system 16, in addition to the structure of the gaming table reading system 1 of the first embodiment, the reading control device 9 includes a reading intensity setting unit 17. Generally, electromagnetic waves are used to read RFID tags. The reading intensity setting unit 17 sets the intensity of the electromagnetic waves used for reading by the reading antenna 7. Furthermore, the reading restriction control device 12 determines the reading restriction antenna 10 to be read restricted according to the intensity set by the reading intensity setting unit 17.

[0116] According to this structure, reading can be limited to a desired range according to the intensity of the electromagnetic wave of the reading antenna 7. When the intensity of the electromagnetic wave of the reading antenna 7 is high, the range of the reading area where the reading is limited is expanded, and conversely, when the intensity of the electromagnetic wave of the reading antenna 7 is low, the range of the reading area where the reading is limited is narrowed, thereby enabling more accurate reading.

[0117] In the first, second, and third embodiments, the gaming table reading system used has been described as reading one reading area at a time, but it may also be configured to read multiple reading areas at a time. That is, it may be configured so that some of the multiple reading antennas read simultaneously, and the reading restriction control device 12 restricts the reading of the reading restriction antenna located between the multiple reading antennas that read simultaneously. Figure 8 Provide explanation.

[0118] Figure 8 from Figure 1 The placement area 4a, the placement area 4b, and the placement area 4c are extracted from the game table 2, and only the reading antenna 7 and the reading restriction antenna 10 required for the explanation are shown. For example, when the player pair sub-area of ​​the placement area 4a and the player pair sub-area of ​​the placement area 4c are read at the same time, the reading antenna 71a and the reading antenna 71c are used to read, and the reading restriction antennas 102a to 105a, 101b to 105b, and 102c to 105c located between these areas are used to restrict reading.

[0119] In the above, a structure in which multiple reads are simultaneously performed on each area within a plurality of placement areas 4 (specifically, the player pair sub-area of ​​placement area 4a and the player pair sub-area of ​​placement area 4c) is described, but a structure in which multiple reads are simultaneously performed on a plurality of placement areas 4 as a whole (for example, the placement area 4a as a whole and the placement area 4c as a whole).

[0120] According to this configuration, it is possible to avoid reading RFID tags in a reading area other than the reading area corresponding to the reading antenna 7 , and it is possible to simultaneously read a plurality of reading areas using a plurality of reading antennas 7 .

[0121] The gaming table reading system used in all the above-mentioned embodiments may be configured to perform the above-mentioned simultaneous multiple readings.

[0122] In this way, when reading multiple reading areas at the same time, although all readings of the multiple reading antennas 7 that are reading at the same time have not been completed, reading errors may occur when entering the next reading. Therefore, for the game table reading system in this application, in the reading control device, after all readings of the multiple reading antennas 7 that are reading at the same time have been completed, another part of the multiple reading antennas 7 are made to read at the same time. This setting can prevent the adjacent reading areas from being read at the same time.

[0123] Thus, in the gaming table reading system of this embodiment, the reading restriction control device 12 determines the reading restriction antenna 10 to be read according to the size of the area to be read by the reading control device 9. Specifically, the larger the area to be read simultaneously, the more reading restriction antennas 10 are made to perform reading restriction. For example, in each placement area 4 Figure 2 In the case of the structure shown in FIG. 1 , a plurality of read antennas 71 to 75 corresponding to a certain placement area 4 may be used simultaneously to read the entire placement area 4 as a read area, or such reading may be performed for each placement area. In this case, since the entire relatively large placement area is used as a read area, more read restriction antennas 10 around the read area may be made to perform read restriction at this time. In addition, all read control devices 9 may be set to read all placement areas at the same time. In this case, the read restriction control device 12 makes all read restriction antennas 10 corresponding to areas other than the placement area perform read restriction.

[0124] (Fourth Embodiment)

[0125] Fig. 9 This is a diagram showing the structure of the gaming table reading system used in the fourth embodiment. In the gaming table reading system 18, in addition to the structure of the gaming table reading system 1 of the first embodiment, a game status determination system 19 for determining the game progress status is further provided. The reading control device 9 causes the reading antenna 7 selected according to the game progress status determined by the game status determination system 19 to perform reading.

[0126] According to this configuration, based on the progress of the game, it is possible to determine the area to be read as early as possible (for example, reading the pair first) and read the necessary area to ensure smooth progress of the game.

[0127] Furthermore, in the first to fourth embodiments described above, in all the readings described above, the read restriction control device 12 has a function of controlling the read restriction by the read restriction antenna 10 so that reading and read restriction are not performed simultaneously in the same read area.

[0128] (Fifth Embodiment)

[0129] Fig.10 This is a diagram showing the structure of the gaming table reading system used in the fifth embodiment. In the gaming table reading system 20, in addition to the structure of the gaming table reading system 1 of the first embodiment, there are paired sub-areas 21a to 21e (hereinafter, collectively referred to as "paired sub-areas 21"). The paired sub-areas 21a to 21e are reading areas that can read RFID tags placed therein, and similarly to the reading areas already described, reading antennas 22a to 22e (hereinafter, collectively referred to as "reading antennas 22") and reading restriction antennas 23a to 23e (hereinafter, collectively referred to as "reading restriction antennas 23") are provided in each paired sub-area. In order to make the figure easier to see, the illustration is omitted, and reading antennas other than the reading antenna 22e are also provided in each paired sub-area 21, and further, they are connected to the reading control device 9 similarly to the reading antenna 22e. In addition, reading restriction antennas other than the reading restriction antenna 23e are also provided in each paired sub-area 21, and further, they are connected to the reading restriction control device 12 similarly to the reading restriction antenna 23e.

[0130] By setting the sub-area 21 in this way, the RFID tags of the game coins 5 are read separately from the placement area 4, so that the RFID tags of the game coins 5 paid out from the game coin tray 6 can be read as early as possible.

[0131] exist Fig.10 In the embodiment, the reading area on the game table 2 is roughly divided into the game coin tray 6, the placement area 4, and the pair area 21. The game table reading system 20 of this embodiment has the following functions: when the reading control device 9 enables the reading antenna 8 of the game coin tray 6 to read, the reading restriction control device 12 enables the reading restriction antenna corresponding to the reading area other than the game coin tray 6 (that is, the reading restriction antenna 10 and the reading restriction antenna 23) to perform reading restriction.

[0132] According to this structure, even when the reading antenna 8 corresponding to the medal tray 6 uses a relatively high-intensity electromagnetic wave, it is possible to prevent the RFID tag on the gaming table other than the medal tray 6 from being misread.

[0133] Furthermore, the gaming table reading system 20 has a function in which, when reading the sub-area 21 , the reading restriction control device 12 causes the reading restriction antennas corresponding to the peripheral area of ​​the sub-area 21 (ie, the reading restriction antennas 10 and 11 ) to restrict reading.

[0134] According to this configuration, when reading the sub-region 21, it is possible to prevent RFID tags in other surrounding reading regions from being mistakenly read.

[0135] exist Fig.10 In the structure, the number of sub-regions 21 is the same as the number of placement regions 4, but it can also be a structure with a number less than the number of placement regions 4 (for example, there is one sub-region 21 in the placement region 4a and the placement region 4b, or there is one sub-region 21 in the placement regions 4a~4e, etc.).

[0136] In the gaming table reading system used in the first to fifth embodiments, a reading control device 9 and a reading restriction control device 12 are respectively provided on the gaming table 2. Alternatively, a gaming table 2 may have two or more reading control devices 9 and reading restriction control devices 12 respectively provided. Alternatively, a gaming table 2 may have a structure in which each reading area is provided.

[0137] In the gaming table reading system used in the first to fifth embodiments, the reading control device 9 starts reading with the next reading antenna when a specified time has passed since the reading antenna that is performing reading no longer reads new information, and the reading restriction control device 12 switches the reading restriction antenna that performs reading restriction synchronously with the switching of such reading antennas in the reading control device 9.

[0138] According to this structure, even if there are multiple RFID tags in the reading area and reading takes time, or there are only a few RFID tags in the reading area, or there are no RFID tags in the reading area and reading is completed in a short time, incomplete reading can be prevented and reading can be performed with higher time efficiency.

[0139] In particular, when multiple read areas are read simultaneously using multiple read antennas and the multiple read areas for simultaneous reading are switched sequentially, the next multiple read areas can be read after no new information is read in the multiple read areas for simultaneous reading. Thus, by changing the combination of the multiple read antennas for simultaneous reading, it is possible to prevent the undesirable situation that adjacent read areas are read simultaneously.

[0140] The reading in the gaming table reading system used in the first to fifth embodiments has functions of simultaneously reading in the same area and restricting reading.

[0141] In the above-mentioned embodiments, all of the above-mentioned reading antennas and reading restriction antennas output electromagnetic waves when reading and reading restriction. In order to prevent the electromagnetic waves from reaching the area that should not be read, it is necessary to control the force of the electromagnetic waves. Therefore, the game table reading system in all embodiments of the present application has a shielding component that adjusts the shape of the magnetic field so that the force of the magnetic field generated by the reading antenna is weakened outside the reading area corresponding to the reading antenna. In addition, the magnetic field is dome-shaped.

[0142] The shielding member is an aluminum plate, tape, film or sheet, and is disposed on the same plane as the reading antenna.

[0143] (Sixth Embodiment)

[0144] Fig.11 This is a diagram showing a gaming table according to the sixth embodiment of the present application. The gaming table (hereinafter referred to as the "table") 6004 has a substantially elliptical or semicircular shape. One side of the table 6004 is used as a dealer position (facing the game coin tray 51 described later), and the other side is provided with a plurality of play positions for players to play games. Fig.11 In the example of FIG. 6004 , five play positions are provided on the underside of table 6004 .

[0145] At the dealer position, a coin tray 51 for the dealer to store the coins 83 is provided in the form of being embedded in the table 6004. The coin tray 51 is double-layered, and the upper layer can be removed, and then the coins 83 of the lower layer can be replenished, or the coins 83 can be taken out.

[0146] The RFID tag 831 is embedded in the game coin 83 (refer to Figure 4 ). At least game coin identification information (hereinafter, also referred to as "game coin ID") for uniquely identifying the game coin is stored in the RFID tag 831. Information indicating the value of the game coin may be further stored in the RFID tag 831.

[0147] Placement areas 41a to 41e (hereinafter, collectively referred to as "placement areas 41") are provided in each play position, and the placement areas 41a to 41e are used by players playing games at the play position to place game coins 83 on the placement objects to play the game. Placement areas 41 are drawn on the upper surface of the table 6004. Adjacent placement areas 41 are divided by one or two lines. The distance between adjacent placement areas 41 is relatively close, and at the closest point, the distance is 0 to 15 cm, for example, smaller than the diameter of the game coin 83.

[0148] Although not shown in the figure, the placement areas 41a to 41e of each playing position are arranged close to each other in the following manner: a player pair placement area for placing a pair in the player's hand; a dealer pair placement area for placing a pair in the dealer's hand; a tie placement area for placing a player's hand and a dealer's hand with the same points; a player placement area for placing a player's hand winning; and a dealer placement area for placing a dealer's hand winning, and these placement areas do not overlap with each other. Hereinafter, these player pair placement areas, dealer pair placement areas, tie placement areas, player placement areas, and dealer placement areas are respectively referred to as "placement object areas". Adjacent placement object areas are divided by one or two lines. Alternatively, lines may not be set between adjacent placement object areas, but the adjacent placement object areas may be distinguished by painting different colors from each other, or the placement object areas may be painted with a color different from the background, thereby dividing each placement object area. The distance between adjacent placement object areas is relatively close. At the closest point, the distance is 0 to 10 cm, for example, smaller than the diameter of the game coin 83 .

[0149] Pair areas 42a to 42e (hereinafter collectively referred to as "pair areas 42") are provided at each play position, and the pair areas 42a to 42e are used to read the game coins paid when the game coins 83 are paid from the dealer to the player. Pair areas 42 are drawn on the upper surface of the table 4. Adjacent pair areas 42 are divided by one or two lines. Alternatively, instead of setting lines between adjacent pair areas 42, adjacent pair areas 42 may be distinguished by painting different colors from each other, or by painting the pair areas 42 with a color different from the background, thereby dividing each pair area 42. In addition, the adjacent pair areas 42 are distinguished from the placement area 41 by one or two lines. Alternatively, instead of setting a line between adjacent pair regions 42 and placement regions 41, the adjacent pair regions 42 and placement regions 41 may be distinguished by painting with different colors, or the pair regions 42 and placement regions 41 may be painted with a color different from the background between them, thereby dividing each pair region 42 and placement region 41. The distance between adjacent pair regions 42 is relatively close, and at the closest point, the distance is 0 to 10 cm, for example, smaller than the diameter of the game coin 83. In addition, the distance between the pair regions 42 and the placement region 41 in each playing position is relatively close, and at the closest point, the distance is 0 to 15 cm, for example, smaller than the diameter of the game coin 83.

[0150] Reading antennas 511a to 511e (hereinafter, collectively referred to as "reading antennas 511") are provided in the placement areas 41a to 41e, respectively, for reading the RFID tags 831 built into the game coins 83 placed in the placement areas 41a to 41e. Reading antennas 521a to 521e (hereinafter, collectively referred to as "reading antennas 521") are provided in the pair areas 42a to 42e, respectively, for reading the RFID tags 831 built into the game coins 83 placed in the pair areas 42a to 42e. A reading antenna 531 is provided in the game coin tray 51 for reading the RFID tags 831 built into the game coins 83 stored in the game coin tray 51. It should be noted that, as described above, the game coin tray 51 is double-layered, and the reading antenna 531 can be provided, for example, on the inner side of the tray of the upper layer.

[0151] In addition, read restriction antennas 512a to 512e (hereinafter collectively referred to as "read restriction antennas 512") are respectively provided in the placement areas 41a to 41e, and the read restriction antennas 512a to 512e are used to restrict or interfere with the RFID tags 831 built into the game coins 83 placed in the placement areas 41a to 41e from being read by the reading antennas in other areas. Read restriction antennas 522a to 522e (hereinafter collectively referred to as "read restriction antennas 522") are respectively provided in the pair areas 42a to 42e, and the read restriction antennas 522a to 522e are used to restrict or interfere with the RFID tags 831 built into the game coins 83 placed in the pair areas 42a to 42e from being read by the reading antennas in other areas. A read restriction antenna 532 is provided in the game coin tray 51, and the read restriction antenna 532 is used to restrict or interfere with the RFID tags 831 built into the game coins 83 stored in the game coin tray 51 from being read by the reading antennas in other areas.

[0152] It should be noted that, in the present embodiment, the read antenna 511 and the read limit antenna 512 of the placement area 41 are shaped along the outer edge of the placement area 41, the read antenna 521 and the read limit antenna 522 of the pair sub-area 42 are shaped along the outer edge of the pair sub-area 42, and the read antenna 531 and the read limit antenna 532 of the coin tray 51 are shaped along the outer edge of the coin tray 51, but the shapes of the antennas are not limited to these. Fig.11 In the example of , the read limit antenna is arranged outside the read antenna, but the positional relationship between the read antenna and the read limit antenna is not limited to this. The read limit antenna may also be arranged inside the read antenna, or the read limit antenna and the read antenna may cross each other in a top view. In addition, multiple read limit antennas may be arranged for one read antenna, and conversely, one read limit antenna may be arranged for multiple read antennas.

[0153] A card issuing device 58 is arranged in the table 6004. The card issuing device 58 stores a plurality of decks of cards. The dealer 91 can draw cards one by one from the card issuing device 58. The card issuing device 58 has a function of reading the suit and face value of the drawn card. The card issuing device 58 determines the game result according to the rules of the card game based on at least the face value of the drawn card. The card issuing device 58 displays the determined game result through a lamp or the like, and outputs data indicating the game result to the outside. In this way, the card issuing device 58 also functions as a game result determination device.

[0154] The table 6004 is also provided with a camera 52 and a card reader 53. The camera 52 captures the face of a player 82 playing the game at the play position and the game tokens 83 on the table 6004. It should be noted that a camera for capturing the face of the player and a camera for capturing the game tokens 83 on the table 6004 may be provided separately.

[0155] The card reader 53 reads the information stored in the membership card 81 by scanning the membership card 81 held by the registered player (member). The membership card 81 has an RFID tag built in, and at least the user ID given to the player is stored in the RFID tag. The card reader 53 has an operation unit (not shown) for the dealer 91 to specify the play position. When the dealer 91 scans the membership card 81 with the card reader 53, the play position is specified. Thus, the combination of the play position and the user ID is output from the card reader 53. In addition, the card reader 53 has a cancel operation unit (not shown). When the player 82 leaves the table, the dealer 91 specifies the play position and operates the cancel operation unit. Thus, the play position and the cancel instruction are output from the card reader 53.

[0156] At the table 6004 as described above, when the player 81 plays a card game, the player 82 first sits at any play position of the table 6004 and hands his membership card 81 to the dealer 91. The dealer 91 scans the membership card 81 using the card reader 53. The player 81 plays the game by placing a game coin 83 in any placement target area of ​​the player area, banker area, tie area, player pair area, and banker pair area of ​​the placement area 41 set at his play position.

[0157] When all players 82 finish placing, the dealer 91 stops placing and draws cards one by one from the card issuing device 58. In a certain card game, four cards are first drawn in the order of the player's hand, the banker's hand, the player's hand, and the banker's hand. At this time, if the player's pair is not established, the game coin placed on the player's pair is recovered by the dealer 91 to the game coin tray 51. In addition, at this time, if the banker's pair is not established, the game coin placed on the banker's pair is recovered by the dealer 91 to the game coin tray 51.

[0158] The dealer 91 draws the cards after the fifth card as needed according to the rules of the card game. When the game result is finally determined, the dealer 91 recycles the placed game coins 83 of the losing player to the game coin tray 51 according to the game result, and then pays the game coins 83 from the game coin tray 51 to the placed game coins 83 of the winning player. When paying, the dealer 91 first temporarily places the game coins 83 in the pair area 42 of the playing position where the placed game coins 83 to be paid are placed, and then places the paid game coins 83 next to the placed game coins 83. In this way, the winning player collects the game coins (payment game coins) placed next to the placed game coins 83 together with the placed game coins. When starting the next game (that is, when starting the placement of the next game), the dealer 91 presses the game start button set in the card issuing device 58.

[0159] Therefore, the game table reading system must read at least the game coins 83 placed on the idle home pair and the dealer pair at the following time: the dealer extracts 4 cards, and the player, depending on the situation, squeezes until the game coins placed on the idle home pair and the dealer pair are recovered. In addition, it is preferred that the reading of all game coins 83 placed is completed at the same time. For this reason, the entire placement area must be read within a few seconds. In addition, the game coins are placed by reading for many times, so that changes can be identified. For example, from the placement cut-off, the first card is extracted from the card issuing device, and the player is prohibited from adding the game coins 83 placed, withdrawing the game coins 83 placed, and changing the placement object, so that it is possible to read for many times, and it can be confirmed whether the game coins 83 placed during the above period change. And then, it can be read from time to time. In this case, the result of the placement game coins read in the time before the placement cut-off can be recorded together with the time data as undetermined placement game coin data.

[0160] Fig.12 This is a block diagram showing the structure of a gaming table reading system according to a sixth embodiment of the present application. The gaming table reading system 100 includes: a card issuing device 58, a player identification system 55, a reading control device 561, a reading restriction control device 562, a management control device 56, a database 57, reading antennas 511, 521, 531, and reading restriction antennas 512, 522, 532.

[0161] The player identification system 55 includes a camera 52, a card reader 53, and a facial recognition device 502. The facial recognition device 502 authenticates the player based on the facial image of the player captured by the camera 52. The facial recognition device 502 can use machine learning technology to perform facial recognition. The facial recognition device 502 also determines the position of the authenticated player based on the facial position of the player, that is, the playing position of the authenticated player. In addition, in the present embodiment, the player can be identified by the facial recognition system including the camera 52 and the facial recognition device 502, and the player can also be identified by reading the membership card 81 using the card reader 53, and the player can be identified by any of these methods.

[0162] The card issuing device 58 outputs the progress of the game (i.e., dealing, from the end of the game to the next game, placement, etc.) to the management and control device 56 based on the button operation and the face value of the drawn card read, and outputs the game result (player hand wins, dealer hand wins, tie, player hand is a pair, dealer hand is a pair, etc.) to the management and control device 56.

[0163] The reading control device 561 controls the reading antennas 511, 521, and 531 to read the RFID tags 831 in the reading area corresponding to the reading antennas. The reading restriction control device 562 controls the reading restriction antennas 521, 522, and 523 to prevent the RFID tags in the reading area corresponding to the reading restriction antennas from being read by the reading antennas corresponding to other reading areas.

[0164] The management control device 56 controls the reading control device 561 and the reading restriction control device 562 to sequentially read the RFID tags of the plurality of reading areas by referring to the information stored in the database 57 as needed according to the progress of the game from the card issuing device 58. The management control device 56 stores the information read from the RFID tags by the reading antenna in the database 57 in association with the player identified by the player identification system 555, thereby updating the database 57. Antenna identification information (antenna ID) for uniquely identifying the reading antenna is added to each of the reading antennas 511, 521, and 531.

[0165] The reading control device 561 sends the information read by the reading antennas 511, 521, and 531 together with the antenna ID of the reading antenna to the management control device 56. It should be noted that the reading control device 561 can be provided for each reading antenna. In this case, in each reading control device 561, reader identification information (reader ID) for uniquely identifying the reading control device 561 can be sent to the management control device 56 instead of sending the antenna ID.

[0166] like Fig.12As shown, the reading antennas 511, 521, and 531 are partially set to an open ring in the corresponding reading area, and one end and the other end of the open end are connected to the reading control device 561. The reading control device 561 reads the RFID tag by flowing current through the reading antenna to form an electromagnetic field (magnetic field) in the reading area.

[0167] One end and the other end of the reading antennas 511, 521, 531 are connected via switches (not shown) in the reading control device 561. The reading control device 561 controls the opening and closing of the switches. Specifically, the reading control device 561 opens the switches for the reading antennas 511, 521, 531 in the reading area where reading is not being performed, thereby opening the loops of the reading antennas 511, 521, 531, so that the electromagnetic field generated by the reading antennas 511, 521, 531 in other adjacent reading areas does not cause an induced current to flow in the reading antennas 511, 521, 531 where reading is not being performed.

[0168] The read restriction antennas 512, 522, 532 are in a ring shape surrounding the corresponding read area, and have switches 521s, 522s, 532s that close or open the loop. The read restriction control device 562 opens and closes the switches 521s, 522s, 532s. The read restriction antennas 512, 522, 532 function to restrict reading when the switches 521s, 522s, 532s are closed to form a closed loop (when short-circuited), and do not restrict reading when the switches 521s, 522s, 532s are opened to open the loop.

[0169] Fig.13 6004a. The substrate 401 for arranging the read antennas 511 and 521 and the substrate 402 for arranging the read limit antennas 512 and 522 are overlapped and arranged below the surface 6004a of the table 6004. In the present embodiment, the substrate 401 is arranged below the substrate 402, but the arrangement order can be changed as appropriate. In addition, the distance between the read antennas 511 and 521 and the read limit antennas 512 and 522 in the vertical direction is appropriately set based on the intensity of the electromagnetic wave, the shapes of the read antennas 511 and 521 and the read limit antennas 512 and 522, etc. Furthermore, the read antennas 511 and 521 and the read limit antennas 512 and 522 can be arranged on the same substrate.

[0170] When reading the reading area 41b, in the reading area 41c adjacent to the reading area 41b, the switch 512s of the reading restriction antenna 512c is closed to form a closed loop. In the reading restriction antenna 512c, a restriction (interference) electromagnetic field (magnetic field) is formed based on the induced electromotive force generated by the electromagnetic field (magnetic field) formed by the reading antenna 511b of the adjacent reading area 41b, and the shape of the electromagnetic field of the reading antenna 511b is adjusted by the electromagnetic field for restriction, so that the reading antenna 511b is restricted (interfered) from reading the game coin 83c placed in the adjacent reading area 41c. That is, on the basis that the electromagnetic field formed by the reading antenna 511b is dome-shaped, the electromagnetic field formed by the reading restriction antenna 512c is a dome-shaped shape opposite to the shape of the electromagnetic field formed by the reading antenna 511b, and only the reading of the reading area 41c corresponding to the reading restriction antenna 512c is restricted. The game coin 83b placed in the reading area 41b corresponding to the energized reading antenna 41b is read by the reading antenna 41b.

[0171] Fig.13 5 shows the intensity distribution 5111b of the electromagnetic field for reading the placement area 41b generated by the reading antenna 511b and the intensity distribution 5111c of the electromagnetic field generated by the reading limiting antenna 511c when reading the placement area 41b. Fig.13 5112b shows the intensity distribution when the electromagnetic field generated by the read antenna 511b is weakened by the electromagnetic field generated by the read limiting antenna 512c of the adjacent placement area 41c, and the intensity distribution 5112c shows the electromagnetic field generated by the read antenna 511c is weakened by the electromagnetic field generated by the read limiting antenna 512b of the adjacent placement area 41c.

[0172] like Fig.13 As shown, even when an electromagnetic field having the following intensity distribution 5111b is generated, by closing the switch of the read limiting antenna 512c of the adjacent placement area 41c, an induced current flows through the read limiting antenna 512c, thereby generating an electromagnetic field for read interference, and as a result, the electromagnetic field generated by the read antenna 511b with the intensity distribution 5111b is adjusted to be sufficiently small and flat in the adjacent placement area 41c, like the electromagnetic field with the intensity distribution 5112b. The intensity distribution 5111b is the intensity distribution for reading the RFID tag 831 of the game coin 83b in the placement area 41b by the read antenna 511b. As a result, the RFID tag 831 of the game coin 83c in the placement area 41c can be prevented from being read by the read antenna 511b.

[0173] In addition, aluminum tapes 513b and 513c are attached to the substrate 402 as shielding components or blocking units for blocking electromagnetic waves from adjacent reading areas. It should be noted that the shielding component can be in a form other than a tape, for example, it can be a plate, a film, a sheet, a coating film, a foil, etc. In addition, the raw material of the shielding component can be a material other than aluminum, for example, it can be silver, gold, copper, nickel, etc., and it can also contain materials such as aluminum, silver, gold, copper, and nickel. Furthermore, the shielding component can be in a grid shape. In addition to the read restriction antennas 512b and 512c, the reading of the read antenna of the adjacent reading area can also be restricted by this shielding component.

[0174] It should be noted that Fig.13 In the example of FIG. 4 , the shielding component is provided on the substrate 402 for configuring the read limit antennas 512 b and 512 c, and the shielding component may be provided on the substrate 401 for configuring the read antennas 511 and 521. Alternatively, the shielding component may be provided on the surface opposite to the read limit antennas 512 b and 512 c in the substrate 402, and may be provided on the surface opposite to the read antennas 511 b and 511 c in the substrate 401. Alternatively, the shielding component may be provided on another plane different from the substrate 401 and the substrate 402.

[0175] The gaming table reading system 100 of this embodiment manages the gaming coins 83 using the database 57. The database 57 stores the information of the RFID tag of the gaming coin 83 in association with the prescribed associated information. The management control device 56 updates the database 57 based on the relationship between the information of the RFID tag read by the reading antennas 511, 521, and 531 and the placement area 41, the placement area 42, and the gaming coin tray 51 as the reading area for reading the RFID tag. In this way, the management control device 56 updates the database 57 for managing the gaming coins 83 based on the information of the RFID tag of the gaming coin 83 read in each reading area of ​​the gaming table 6004.

[0176] Next, the management of the game tokens 83 by the database 57 will be described. Fig.14 83 and the data structure of the database 57. As described above, the game coin 83 has an RFID tag 831 built in. The RFID tag 831 stores the game coin ID 573. The database 57 has two tables, including a game coin management table 571 for managing the game coin 83 and a user management table 572 for managing users.

[0177] In the game coin management table 571, the game coin ID 573 of the game coin 83 is associated with the price information 574 of the game coin 83 as the associated information, the user identification information (user ID) 575 for uniquely identifying the user holding the game coin, and the location information 576 indicating the location of the game coin 83. It should be noted that, for the game coin ID 573, the price information 574 does not change, but the user ID 575 and the location information 576 associated with the game coin ID 573 change because the game coin 83 is used in the entertainment venue. Therefore, in the database 57, for the game coin ID 573, a certain past user ID and location information can be stored on the basis of the latest user ID and location information, or only the latest user ID and location information can be stored.

[0178] In the user management table 572, the user ID 575 of each user is associated with the value information 574 of the game coins owned by the user, the placement information 577 indicating the historical records of the game coins placed by the user in the game, and the location information 576 indicating the location of the user as the associated information. The value information 574, the placement information 577, and the location information 576 associated with the user ID 575 change as the game coins 83 are used in the casino. Therefore, in the database 57, for the user ID 575, in addition to the latest value information, placement information, and location information, certain past value information, placement information, and location information may be stored, or only the latest value information, placement information, and location information may be stored.

[0179] The gaming table reading system 100 manages the gaming coins 83 by updating the gaming coin management table 571 and the user management table 572 of the database 57 based on the information of the RFID tag 831 read by the reading antenna.

[0180] It should be noted that in the following description, the management control device 56 updates the database 57, and the management control device 56 updates the database based on the information of the RFID tags 831 read by each reading antenna and the game status when reading it. In this embodiment, the management control device 56 obtains information on the game status (in the game, placed, cleared, paused, etc.) from the card issuing device 58 to grasp the game status.

[0181] First, the management control device 56 updates the game coin management table 571 of the database 57 in a manner that associates the user ID of the user who won the game with the game coin ID of the game coin 83 paid to the winning user in the game. In addition, the management control device 56 updates the game coin management table 571 of the database 57 in a manner that associates the user ID assigned to the dealer with the game coin ID of the game coin 83 placed by the losing user in the game. Thus, even if the holder of the game coin 83 changes due to the use of the game coin 83 in the game, the game coins held by each user can be determined by referring to the database 57.

[0182] In addition, the management control device 56 updates the database 57 in a manner that associates the user ID of the user playing the game at the play position corresponding to the pair of sub-areas 42 with the game coin ID of the game coin 83 read in the pair of sub-areas 42. The user ID of the user playing the game at each play position can be determined by the player determination system 55 according to the above-mentioned embodiment.

[0183] Specifically, the management control device 56 records the user ID of the user at the playing position of the sub-area 42 in the record of the game coin ID of the game coin 83 read from the sub-area 42 in the game coin management table 571 of the database 57. The database 57 is updated in this way, so that the database 57 can reflect that the holder is changed from the dealer to the user due to the payment.

[0184] Furthermore, the management control device 56 updates the user management table 572 in the user management table 57 of the database 57 by adding the value information 574 associated with the user ID 575 of the user who won the game to the value of the game coin 83 paid to the user who won the game, and subtracting the value of the game coin 83 recovered from the losing user in the game from the value information 574 associated with the user ID 575 of the losing user in the game. By updating the database 57 in the above manner, the value of the game coin 83 held by each user, that is, the amount held, can be managed by the database 57.

[0185] In addition, when the management control device 56 reads the game coin ID of the paid game coin 83 in the pair of sub-areas 42, it updates the database 57 by associating the user ID associated with the game coin 83 placed in the placement area 41 corresponding to the pair of sub-areas 42 and the game coin ID of the paid game coin 83.

[0186] Alternatively, when the management control device 56 reads the game coin ID of the paid game coin 83 in the placement area 41, it updates the database 57 in a manner that associates the user ID associated with the game coin 83 placed in the placement area 41 with the game coin ID of the paid game coin 83. Thus, the database 57 can be updated so that the placed game coin 83 and the holder of the paid game coin 83 are the same.

[0187] In addition, when all the playing positions are used and there is a player who places the game behind, that is, when multiple players place the game at one playing position, the management control device 56 also manages the game coin 83 as described below. That is, when the player identification system 55 can determine the user IDs of two users who are simultaneously present at the same playing position, the management control device 56 manages the game coin 83 for each user in the same manner as described above, but when the player identification system 55 can determine the user ID of one of the two users playing the game at the same playing position and cannot determine the other user identification information, the dealer pays according to the operation rule of giving priority to the player whose user ID is confirmed. The management control device 56 updates the database 57 in a manner that associates the game coin ID of the game coin 83 paid first at the playing position with the user ID determined by the player identification system 55. The management control device 56 associates the game coin ID of the game coin 83 paid later with "unknown" as the user ID.

[0188] The reading antenna and the reading control device 561 for reading the RFID tag 831 built into the game coin 83 can be set at various locations in the casino facility. In this case, the reading control device 561 can be set at various locations in the casino facility, and the management control device 56 can communicate with these multiple reading control devices 561. As described above, the information of the RFID tag 831 read by the reading antenna and the antenna ID of the reading antenna or the reader ID of the reading control device 561 are sent to the management control device 56 from the reading control device 561. The management control device 56 has a table that associates the information of the location of the reading antenna corresponding to each antenna ID or each reader ID (location information, such as the card pack number, table number, game coin tray number, entrance and exit number, etc. for identifying the card pack, table, game coin tray, entrance and exit, etc.).

[0189] If the reading control device 561 sends the read game coin ID together with the antenna ID (or reader ID) to the management control device 56, the management control device 56 updates the location information 474 associated with the game coin ID in the game coin management table 571 of the database 57. In addition, the management control device 56 also updates the location information 576 associated with the game coin ID in the user management table 572.

[0190] Thus, by referring to the database 57, it is possible to know which position each game coin 83 is in, and which position each user is in. In addition, by in the game coin management table 571 and the user management table 572, past information is also stored as location information, thereby it is possible to know the historical records of the changes of game coins 83 and users.

[0191] Furthermore, if the management control device 56 obtains information on the user ID of the user who is playing the game at each play position from the player identification system 55, and, during placement, places the game coin 83 in the placement area 41 to play the game, the management control device 56 obtains the game coin ID as information of the RIFD tag from the reading antenna 511 of each play position. The management control device 56 uses the user ID and the game coin ID to update the user management table 572 of the database 57. Specifically, the management control device 56 refers to the game coin management table 571, obtains the value information 574 of the game coin ID 573 that has been obtained, and adds the value of the value information 574 to the placement information of the user ID obtained in the user management table 572.

[0192] In this way, the management control device 56 updates the database 57 in such a manner that the value of the game coin 83 read by the reading antenna 511 of the placement area 41 is added to the placement information 577 associated with the user ID 575, wherein the user ID 575 is the user ID of the user determined for the playing position corresponding to the reading antenna 511. By updating the database 57 as described above, the value of the placed game coin 83, that is, the placement amount, can be managed for each user through the database 57. It should be noted that the placement amount can be managed as the bonus points corresponding thereto.

[0193] The information stored in the RFID tag 831 of the game coin 83, i.e., the game coin ID 573, is used to determine the authenticity of the game coin 83. When the reading antenna reads the information of the RFID tag 831, the management control device 56 compares the information with the database 57. When the information does not exist in the database 57, i.e., when the comparison is unsuccessful, the game coin 83 is judged to be a bad or cheating game coin. In the case where the game coin 83 is judged to be a bad or cheating game coin, the management control device 56 outputs a warning. Thus, in the case where cheating game coins 83 are used in the game table 6004, a warning can be output. The output warning can be output in a form that can be perceived visually or auditorily in a timely manner (i.e., at the moment when the game coin is judged to be a bad or cheating game coin), or it can also be recorded in a recording device together with the status information (table number, date and time, etc.) of the cheating and bad game coins.

[0194] Fig.15FIG. 2 is a diagram showing another example of a read antenna and a read limit antenna. In this example, a read antenna is provided in each play position and in each placement object, i.e., each player, banker, and tie, pair, etc. Fig.15 As shown, each placement area 41 has multiple placement object areas, which include a player area 411, a banker area 412, a tie area 413 as a side placement area, a player pair area 414, and a banker pair area 415 which are adjacent to each playing position.

[0195] Reading antennas and reading restriction antennas are provided in the respective reading areas, i.e., the placement target areas, so that the respective placement target areas can be read. That is, reading antenna 5111 and reading restriction antenna 5112 are provided in the player area 411, reading antenna 5121 and reading restriction antenna 5122 are provided in the banker area 412, reading antenna 5131 and reading restriction antenna 5132 are provided in the tie area 413, reading antenna 5141 and reading restriction antenna 5142 are provided in the player pair area 414, and reading antenna 5151 and reading restriction antenna 5152 are provided in the banker pair area 415.

[0196] In this way, each placement object area in each play position is used as a different reading area, and a reading antenna is set respectively, so that it can be determined on which placement object the player places the game coin 83 at each play position. Fig.15 The gaming table reading system 100 can read the RFDI tag 831 in each of these reading areas. The management control device 56 can determine which player at which playing position has won the game, that is, which playing position should be paid, based on the information of the game result in the card issuing device 58 and the information of the placed object obtained from each playing position. If the judgment result is inconsistent with the actual payment, the management control device 56 can detect this and output a warning.

[0197] Fig.16 FIG. 2 is a diagram showing another example of a read limiting antenna. Fig.16 In the example, only the placement areas 41b, 41c, 41d and their corresponding sub-areas 42b, 42c, 42d are shown. In this example, a plurality of read limiting antennas are provided in the placement area as a read area. These plurality of read limiting antennas respectively adjust the shape of the electromagnetic field generated by the read antennas of the adjacent plurality of other read areas.

[0198] Specifically, for example, in the placement area 41c as the reading area, in addition to the reading antenna 511c that reads the entire placement area 41c as a whole, three reading restriction antennas 512c1, 512c2, and 512c3 are provided. The reading restriction antenna 512c1 is set so that the RFID tag 831 of the game coin 83 placed in the placement area 41c is not read by the reading antenna 511d of the placement area 41d adjacent to the right. The reading restriction antenna 512c2 is set so that the RFID tag 831 of the game coin 83 placed in the placement area 41c is not read by the reading antenna 511b of the placement area 41b adjacent to the left. The reading restriction antenna 512c3 is set so that the RFID tag 831 of the game coin 83 placed in the placement area 41c is not read by the reading antenna 521c of the pair area 42c adjacent to the upper side.

[0199] When the reading control device 561 controls the reading antenna 511d to read the placement area 41d, the reading restriction control device 562 closes the switch of the reading restriction antenna 512c1 of the placement area 41c, so that the reading restriction antenna 512c1 generates electromagnetic waves for interfering with the reading antenna 511d reading the RFID tag 831 of the placement area 41c. When the reading control device 561 controls the reading antenna 511b to read the placement area 41b, the reading restriction control device 562 closes the switch of the reading restriction antenna 512c2 of the placement area 41c, so that the reading restriction antenna 512c2 generates electromagnetic waves for interfering with the reading antenna 511b reading the RFID tag 831 of the placement area 41c. In addition, when the reading control device 561 controls the reading antenna 521c to read the sub-area 42c, the reading restriction control device 562 closes the switch of the reading restriction antenna 512c3 of the placement area 41c, so that the reading restriction antenna 512c3 generates electromagnetic waves for interfering with the reading antenna 521c reading the RFID tag 831 of the placement area 41c.

[0200] In this way, the read limit control device 562 and the read control device 561 sequentially drive the read antenna to read synchronously, close the switch of the corresponding read limit antenna, and generate interference electromagnetic waves.

[0201] As described above, according to the gaming table reading system 100 of the present embodiment, when a plurality of reading areas are set at relatively close intervals on the gaming table 6004, it is possible to read in which reading area the RFID tags 831 are located. Specifically, even when a plurality of placement areas are set at relatively close distances, by providing a reading antenna in each placement area 41, it is possible to prevent the reading antenna from reading the RFID tags 831 of the adjacent placement areas 41 and the pairing areas 42. Furthermore, even when a pairing area 42 is provided corresponding to each of the plurality of placement areas 41, when a reading antenna is provided therein, it is possible to prevent the RFID tags 831 of the adjacent pairing areas 42 and the placement area 41 from being read.

[0202] It should be noted that, in the sixth embodiment described above, the read limit antennas 512, 522, 532 generate an electromagnetic field for interfering with the reading of the corresponding read area due to the induced current generated by the electromagnetic field generated by the read antennas 511, 521, 531 of the adjacent read area, but instead, the electromagnetic field for interference may be generated by passing a current from the read limit control device 562. In addition, even in this case, when a switch that blocks the loop is provided in the read limit antennas 512, 522, 532, when the read antennas 511, 521, 531 provided in the same read area perform reading, the switch may be turned on to open the loop.

[0203] Fig.17A as well as Fig. 17B 1 is a diagram for explaining the driving of the read antenna of the switching read control device 561 and the read limit antenna of the read limit control device 562. Fig.17A as well as Fig. 17B In FIG. 1 , only the read antennas 511a to 511e and the read restriction antennas 512a to 512e of the placement areas 41a to 41e and the read antennas 521a to 521e and the read restriction antennas 522a to 522e of the sub-areas 42a to 42e are shown. Fig.17A as well as Fig. 17B In the figure, the read antenna and read restriction antenna shown by thin solid lines represent the situation where the loop is open and not driven (not activated), the read antenna shown by thick solid lines represents the situation where reading is performed, and the read restriction antenna shown by dotted lines represents the situation where read restriction (interference) is performed.

[0204] The read control device 561 and the read limit control device 562 repeat alternately Fig.17A The state (first state) and Fig. 17B state (second state), thereby reading all placement areas 41a to 41e and sub-areas 42a to 42e. Specifically, in Fig.17AIn the first state, the reading antennas 511a, 511c, 511e, 521b, and 521d are driven to read the placement areas 41a, 41c, and 41e and the sub-areas 42b and 42d, and the reading restriction antennas 512b, 512d, 522a, 522c, and 522e are short-circuited to perform reading restriction.

[0205] exist Fig. 17B In the second state, the read antennas 511b, 511d, 521a, 521c, and 521e are driven to read the placement areas 41b and 41d and the sub-areas 42a, 42c, and 42e, and the read restriction antennas 512a, 512c, 512e, 522b, and 522d are short-circuited, thereby performing read restriction. In this way, in the first state and the second state, the read restriction antennas are short-circuited for the read areas above, below, left, and right of the read area read by the read antenna, and read restriction is performed, thereby limiting the reading of the RFID tags 831 located outside the read area that each read antenna is responsible for, and reading multiple read areas at the same time. In this way, a group is formed by multiple read areas, and the read control device 561 and the read restriction control device 562 switch the read area to be read according to each group, so that all read areas can be read efficiently and quickly.

[0206] It should be noted that in Fig.17A as well as Fig. 17B In the example, the multiple reading areas including the placement areas 41a to 41e and the sub-areas 42a to 42e are divided into 2 groups, and the multiple reading areas can also be divided into 3 or more groups. In addition, according to the situation of the game, the multiple reading areas to be grouped can be limited to partial reading areas. For example, when paying, only the sub-areas 42a to 42e can be divided into multiple groups, and the groups to be read can be switched in sequence, so that all the sub-areas 42a to 42e are read. In addition, there can also be a group consisting of only one reading area. For the recovery and payment of game coins, they are carried out in sequence from the playing position at the right end to the left or from the playing position at the left end to the right, respectively, so that the areas to be recovered and paid can be read emphatically.

[0207] In addition, when the reading antennas for reading are switched sequentially, the reading time can be fixed for each reading antenna or each group. In this case, the reading time can be set to be the same for each reading antenna or each group, or can be set individually. Fig.17A The read area to be read in the first state is set as the first group, and the Fig. 17B The reading area for reading in the second state is set as the second group, and the game coin tray 51 is set as the third group. When three groups are set, the reading time of the third group can be set longer than the reading time of the first group and the second group.

[0208] In addition, the management control device 56 may store a combination table for each read area, the combination table defining: the read area or the read antenna corresponding to the read area, the read area to be read restricted when reading the read area, or the read restriction antenna corresponding to such a read area. Furthermore, when the management control device 56 determines the read area to be read, it may indicate the intention to the read control device 561, and refer to the combination table to determine the read area to be read restricted or the read restriction antenna to be read restricted, and instruct the read restriction control device 562.

[0209] In this case, the management control device 56 can determine the read area to be read based on the instruction of the operator (e.g., the dealer). In addition, the management control device 56 can determine the read area to be read based on the image obtained by the camera 52. For example, the management control device 56 can determine in the following manner: the image obtained by the camera 52 is analyzed, and the read area in which the game coin 83 is judged to have a change as a result of the analysis is read.

[0210] Figures 18A to 18E FIG. 1 is a diagram showing another example of switching the read area for reading in a plurality of read areas when reading simultaneously. Fig.17A as well as Fig. 17B Instead of forming a fixed group as shown in the example of , the positions of a plurality of read areas that do not interfere with each other are shifted, thereby sequentially switching the read areas to be read.

[0211] In this example, if Fig.18A As shown, for the placement areas 41a to 41e, the read areas 41a and 41c are read, and then, as shown in Fig.18B As shown, the read areas 41b and 41d are read, and then, as shown Fig. 18C As shown, read the read area 41c, 41e, then, as Fig.18D As shown, the read areas 41d and 41a are read, and then, as shown Fig.18E As shown, read the read area 41e, 41b, and then again as Fig.18A As shown, the reading areas 41a and 41c are read, and this is repeated. In this way, the combination of the reading areas to be read simultaneously is not fixed, and multiple reading areas can be read simultaneously.

[0212] It should be noted that in the above-mentioned embodiment, adjacent reading areas may be connected to each other with one line between the reading areas as a boundary, or an area not serving as a reading area may be sandwiched between adjacent reading areas, or two lines may be provided between adjacent reading areas.

[0213] Fig.19 1 is a diagram showing another example of the layout of the game table of the present embodiment. Six play positions are provided on the game table 40. The play positions are assigned play position numbers 1 to 7 (excluding 4). Each play position is configured with a player area 411 and a banker area 412. The tie, player pairs, and banker pairs placed sideways are not configured in each play position, but are configured together as a tie area 403, a player pair area 404, and a banker pair area 405. That is, the tie area 403, the player pair area 404, and the banker pair area 405 are all divided into small areas according to each play position.

[0214] In this case, a reading antenna and a reading restriction antenna are respectively provided in the small areas of each playing position of the tie area 403, the player pair sub-area 404, and the banker pair sub-area 405, and these small areas are respectively used as reading areas, and read respectively at each playing position. In addition, a reading antenna and a reading restriction antenna are also respectively provided in the player area 411 and the banker area 412, and each reads separately. Even in such an antenna configuration, the reading control device 561 and the reading restriction control device 562 can switch the reading antenna for reading and the reading restriction antenna for reading restriction, so as to read only the RFID tags of the reading area that each reading antenna is responsible for, and not read the RFID tags of other reading areas.

[0215] For example, the reading control device 561 and the reading restriction control device 562 can be set to simultaneously read small areas with the same playing position numbers in the hand area 403, the player pair sub-area 404, and the banker pair sub-area 405, and to restrict reading in small areas with all other playing position numbers, and to switch the playing position numbers of the small areas to be read in turn.

[0216] In addition, if Fig.11 As shown, a camera 52 can be set on the table 6004, and the game coin 83 placed on the table 6004 can be photographed by the camera 52. At this time, a game coin recognition device can be further used, which recognizes the position (which reading area), type, and number of game coins 83 by performing image recognition on the image obtained by the shooting of the camera 52. The camera 52 shoots the game coin 83 placed on the table 6004 according to the tilt information. In order to visually determine the type of the game coin 83 when observing the side, the game coin 83 has a band with different colors according to the type on the side. The game coin recognition device recognizes the position, type, and number of the game coin 83 by appropriately combining and utilizing image analysis technologies such as neural networks and pattern matching.

[0217] The management control device 56 uses the recognition result of the game coin recognition device and the reading result obtained from the reading control device 561 to grasp what kind of game coins are placed where and how many. At this time, when the recognition result of the game coin recognition device and the reading result obtained by the reading control device 561 are inconsistent, the management control device 56 can record a warning or output a warning. In particular, when the information of the game coin 83 recognized by the game coin recognition device cannot be obtained by the reading control device 561, it means that there are game coins 83 without a valid RFID tag 831. Therefore, in this case, a warning that there are cheating game coins can be output.

[0218] In addition, in the sixth embodiment, by grasping which position of the game coin 83 with which game coin ID is placed on the table 6004, the database 57 is updated to track the movement of the game coin 83. The purpose of the technology of this embodiment is not limited to this. For example, a system for detecting cheating by grasping which position of the game coin 83 with which game coin ID is placed on the table 6004 can also be constructed. In this cheating detection system, for example, the management control device 56 can determine that cheating exists when there is an increase or decrease in the placement area 41 or when there is movement of the game coin 83 in the placement area 41 during the period from the start of drawing cards to the end of clearing.

[0219] (Seventh Embodiment)

[0220] Fig. 20 FIG. 1 is a diagram showing an example of the configuration of the antenna according to the seventh embodiment of the present invention. Figure 20 to Figure 24 In FIG. 1 , the wiring from the reading antenna to the reader and the switch for reading the limit antenna are omitted. Fig. 20 In the example, a reading antenna 61a to 60e (hereinafter, collectively referred to as "the placement area 60") of each player position is provided with a reading antenna 61a to 60e (hereinafter, collectively referred to as "the placement area 60"). In addition, an external reading restriction antenna 62a to 62e is provided in the placement area 60a to 60e of each player position in a manner surrounding the reading antenna 61a to 61e. The external reading restriction antenna 62a to 62e is always closed and always exerts an interference effect. In particular, for example, when the reading antenna 61a reads in the placement area 60a, the external reading restriction antenna 62a of the placement area 60a generates an interference magnetic field using an induced current so that the reading antenna 61a does not read the RFID tag 831 of the game coin 83 placed in other adjacent placement areas 60b, etc. Since the reading antenna 61a and the external reading restriction antenna 62a are sufficiently far apart, the interference magnetic field does not interfere with the reading antenna 61a reading the RFID tag 831 of the game coin 83 of the corresponding placement area 60a.

[0221] In this way, when the placement areas 60a to 60e as multiple reading areas are arranged sufficiently far from each other, it is effective to provide the external reading restriction antennas 62a to 62e that are always closed and surround the reading antennas 61a to 61e at sufficient intervals for each reading antenna 61a to 61e. It should be noted that in this embodiment, since the reading antenna 61 is arranged in a range larger than the placement area 60, the RFID tag 831 of the game coin 83 placed slightly away from the placement area 60 can be reliably read.

[0222] Fig.21 FIG. 1 is a diagram showing the structure of an antenna at a player's position according to the seventh embodiment of the present invention. Fig.21 All antennas are plotted in (a). Fig.21 (b)~ Fig.21 In (e), the read antenna 61a is shown together with the placement area 60a and the substrate 66a. Fig.21 (b)), read limit antenna 63a ( Fig.21 (c)) and the read limit antenna 64a ( Fig.21 (d)), read limit antenna 65a ( Fig.21 (e)). Fig.21 As shown, a substrate 66a is provided for the placement area 60a and an external read limiting antenna 62a is provided surrounding the substrate 66a. A read antenna 61a and a plurality of read limiting antennas 63a to 65a are provided on the substrate 66a.

[0223] The plurality of read restriction antennas 63a to 65a are antennas that are turned on and off by switches, and are arranged at positions corresponding to the inside of the placement area 60a, which is a reading area. The read restriction antenna 63a is arranged in the upper half of the placement area 60a, the read restriction antenna 64a is arranged in the lower half of the placement area 60a, and the read restriction antenna 65a is arranged in the left and right areas of the center of the placement area 60a. In this way, the read restriction antennas 63a to 65a are arranged to cover the entire area of ​​the placement area 60a, which is a reading area, but the read restriction antenna is locally arranged in the part that is easily read by other read antennas. Specifically, since the left and right areas of the center are easily affected, the read restriction antenna 65a is arranged in a manner to be located in the left and right areas of the center.

[0224] The reading of the reading area by the reading antenna 61 and the turning on / off of the interference function by the opening and closing of the switch of the reading limit antennas 63 to 65 are controlled by an RFID reader not shown. In the case of reading multiple reading areas simultaneously using multiple reading antennas 61, more than the number of RFID readers that can be read simultaneously are provided, and these multiple RFID readers can control the timing of reading and turning on / off the interference function synchronously with each other.

[0225] Thus, in this embodiment, interference is implemented by sharing each small area of ​​the entire placement area 60a with multiple read restriction antennas 63a to 65a. It should be noted that these read restriction antennas 63a to 65a are antennas that close the switch to form a closed circuit and play an interference function when the read antenna 61b of other placement areas 60b is reading. When the read antenna 61a of the placement area 60a is reading, the switch of the read restriction antenna 63a to 65a of the placement area 60a is open and does not function as an interference antenna. The read restriction antenna 63a to 65a of the placement area 60a is opened only when reading the placement area 60a, and the switch is closed to form a closed circuit when reading in areas other than the placement area 60a. It should be noted that the situation that two placement areas that are sufficiently separated, for example, the placement area 60a and the placement area 60c can be read at the same time is the same as the above embodiment.

[0226] When the reading antenna 61a finishes reading the placement area 60a, the next step is to read the placement area 60b, which is another reading area. Specifically, when the reading of the placement area 60a is finished, first (1) the power supply to the reading antenna 61a of the placement area 60a is turned off, then (2) the switches of the reading limit antennas 63a to 65a of the placement area 60a are closed (the interference function is turned on), and (3) the switch of the reading limit antenna 63 of the placement area 60b is turned on (the interference function is turned off), and then (4) the power supply to the reading antenna 61b of the placement area 60b, which is the next reading area, is turned on. According to this sequence, the interference of the placement area 60a can be effectively exerted before the reading of the placement area 60b is started, and a reading error can be prevented when switching the reading area.

[0227] When multiple readings are repeated in one reading area (one reading antenna), and the reading is stable during the multiple readings, it is determined that the reading of the reading area (reading antenna) is completed. At this time, the RFID reader as a reading control device for reading is configured to designate the identification information of the RFID tag 831 that has been read in the multiple readings as the reading is completed, so that only the new RFID tag 831 is read. As a result, the RFID reader repeatedly reads, and when no new RFID tag 831 is read, it is determined that the reading is stable and the reading of the reading area (reading antenna) is completed. Alternatively, a mark indicating that the reading is completed can be set for the RFID tag 831 that has been read to avoid repeated reading. Alternatively, when the RFID reader repeatedly reads the RFID tag each time in the multiple readings, if the reading result continues for a specified number of times (for example, two or three times), it is determined that the reading of the reading area (reading antenna) is completed.

[0228] (Eighth Embodiment)

[0229] Fig. 22 FIG. 8 is a diagram showing the arrangement of antennas according to the eighth embodiment of the present invention. Fig. 22 In the example of FIG. 1 , antenna substrates 76a to 76e are shown, which correspond to a plurality of placement areas 70a to 70e, respectively. The plurality of placement areas 70a to 70e are provided corresponding to a plurality of player positions. Fig. 22 In the example of , each substrate 76a to 76e is arranged in a manner that the substrates 76a to 76e are extremely close to each other or in contact with each other. Fig. 22 In the example shown in FIG. 1 , substrates 76 to 76e are slightly larger than placement areas 70a to 70e, respectively.

[0230] Fig.23 FIG. 8 is a diagram showing a placement area according to an eighth embodiment of the present invention. Fig.23 In the figure, although the placement area 70a is shown as a representative, the placement areas 70b to 70e are the same. In the placement area 70a, a relatively small player pair area 701a, a tie area 702a, and a banker pair area 703a are arranged side by side in the upper section, a relatively large banker area 704a is arranged in the middle section, and a relatively large player area 705a is arranged in the lower section. That is, the player pairs, tie and banker pairs, which are called side placement, are arranged at a position relatively far from the player and are designed to be relatively small.

[0231] Fig.24 1 is a diagram showing the relationship between the substrate, the antenna, and the placement area according to the eighth embodiment of the present invention. Fig.24The figure shows the placement area 70a, but the placement areas 70b to 70e are the same. In this embodiment, the substrate 76a is provided with reading antennas 721a to 725a corresponding to the player pair area 701a, the tie area 702a, the banker pair area 703a, the banker area 704a, and the player area 705a (hereinafter, each area is referred to as a "placement object") of the placement area 70a. That is, each placement object of the placement area 70a of each player position is provided with a reading antenna that is controlled independently of each other.

[0232] In addition, the substrate 76a is provided with read-limiting antennas 731a to 741a corresponding to each of the placement objects 701a to 705a and controlled independently. Specifically, one read-limiting antenna 731a to 733a is provided in each of the placement objects 701a to 703a placed on the relatively small side, four read-limiting antennas 734a to 737a are provided in the relatively large banker area 704a, and four read-limiting antennas 738a to 741a are provided in the relatively large player area 705a. It should be noted that Fig.24 In FIG. 1 , the switches of the read limiting antennas 731 a to 741 a are omitted from illustration.

[0233] According to this structure, in the game table reading system of this embodiment, the RFID tags 831 of the game coins 83 placed on each placement object can be read respectively according to each placement object 701-705 of the placement area 70a-70e assigned to each player position. Specifically, when the RFID tag 831 of the game coin 83 is read on a certain placement object in a placement area, the switch of the reading restriction antenna of other placement objects in the same placement area is closed, and the interference function is turned on. In this way, the possibility of the reading antenna of a certain placement object reading the RFID tag of the game coin 83 placed on other placement objects can be reduced.

[0234] As shown in the seventh embodiment, when the entire placement area of ​​each player's position is read, when the reading area that the reading antenna is responsible for is relatively large, the antenna power must be enhanced, but when the placement area is divided into each placement object and read as shown in this embodiment, it is not only possible to determine which placement object the player has placed, but also the antenna power applied to each reading antenna can be relatively weak, which can reduce the possibility of mistakenly reading other placement objects placed at a relatively close distance, and even reduce the possibility of mistakenly reading the RFID tag 831 of the game coin 831 placed in the adjacent placement area. It should be noted that in this embodiment, for the relatively large dealer area 704a and the idle home area 705a, multiple independent read limit antennas are set, so that sufficient interference effect can be obtained. It should be noted that for the relatively small side placement object, the antenna power of its reading antenna is also relatively weak, and the limit of the number of stacked game coins 83 that can be read is also relatively small compared with the relatively large dealer area 704a and the idle home area 705a.

[0235] In this embodiment, when reading multiple reading areas at the same time, control is performed in a manner that avoids multiple reading antennas in the same placement area from reading at the same time, and avoids reading multiple placement objects in adjacent placement areas. For example, when any one of the reading antennas 721a to 725a in the placement area 70a reads, at the same time, the other reading antennas in the placement area 70a and any one of the reading antennas 721b to 725b in the adjacent placement area 70b do not read, but are read by, for example, the reading antenna in the placement area 70c. Even in this case, when the relatively large reading antennas 724a and 725a among the reading antennas 721a to 725a in the placement area 70a read, in the reading area 70c, the relatively small reading antennas 721c to 723c among the reading antennas 721c to 725c can also read. Through this control, the possibility of interference caused by the simultaneous operation of multiple reading antennas with strong antenna power is greatly reduced.

[0236] It should be noted that, in the present embodiment, the RFID reader controlling the reading antennas 721 to 725 and the reading restriction antennas 731 to 741 is synchronously controlled together with the RFID reader controlling the reading antenna disposed on the game coin tray. For example, it can be set so that when the reading antenna of the game coin tray is used to read the RFID tag 831 of the game coin 83 stored in the game coin tray, the reading antenna of any placement area does not read. For example, after the game result is determined, in the case of a clearing including the recovery of lost game coins and the repayment of won game coins, the reading antenna of the game coin tray can be controlled to repeatedly read the RFID tag 831 of the game coin 83 stored in the game coin tray. In addition, the reading antenna of the placement area can be set so that it repeatedly reads while changing the reading position during the period from the end of the clearing and the player being able to place for the next game to the determination of the game result. Through this reading, the gaming table reading system can determine the placement objects and placement amounts of the game coins 83 placed on each placement area 70a~70e, and after NMB (placement end), monitor whether there is any improper movement of the game coins 83 (improper increase (pitching) of placed game coins after the start of the game, improper decrease (capping) of placed game coins after the start of the game, post-placement, etc.), and after the game result is determined, monitor whether the dealer has correctly performed the settlement.

[0237] (Ninth Embodiment)

[0238] Fig.25 1 is a diagram showing the structure of a gaming table reading system according to a ninth embodiment of the present invention. The gaming table 6005 has a player position where a player 82 is located and a dealer position where a dealer 91 is located. On the player position side, a plurality of placement areas 80a to 80e are arranged on the tabletop of the gaming table 6005. A coin tray 51 is provided on the dealer position side. A dealer area 90 is arranged on the tabletop of the gaming table 6005 between the coin tray 51 and the plurality of placement areas 80a to 80e.

[0239] The coin tray 51 is provided with a reading antenna for reading the RFID tag 831 of the coin 83 stored in the coin tray 51. In addition, each placement area 80a to 80e is also provided with a reading antenna and a reading restriction antenna according to any of the above embodiments. In this embodiment, the dealer area 90 is also provided with a reading antenna 92 ​​and a reading restriction antenna 93.

[0240] The dealer area 90 is an area for temporarily placing game coins 83 taken out from the game coin tray 51 when the dealer 91 pays the game coins 83 to the game winning player 82 from the game coin tray 51. The game coins 83 paid to the game winning player 82 can be determined by reading the RFID tags 831 of the game coins 83 by the reading antenna 92 ​​of the dealer area 90. The reading antenna 92 ​​of the dealer area 90 does not read other adjacent placement areas at the same time.

[0241] Specifically, the read area to be read may be switched in the order of reading the placement areas 80a to 80e in sequence and then reading only the dealer area 90. In the multiple read areas including the multiple placement areas 80a to 80e and the dealer area 90, the multiple read areas may be read simultaneously in a manner that the adjacent read areas are not read at the same time. Alternatively, the dealer area 90 may be read at a timing corresponding to the progress of the game. That is, the multiple placement areas 80a to 80e may be read in sequence during the placement period and the game, and the multiple placement areas 80a to 80e and the dealer area 90 may be read in sequence during the clearing period.

[0242] The game table 6005 of this embodiment is further provided with a metal wire 6010 which also serves as a decoration of the game table in a manner that surrounds the entire area of ​​the plurality of placement areas 80a to 80e and the dealer area 90. The metal wire 6010 forms a closed loop that surrounds the entire area of ​​the plurality of placement areas 80a to 80e and the dealer area 90. It should be noted that the coin tray 51 is located outside the closed loop.

[0243] According to this structure, the metal wire 6010 functions as a read-limiting antenna for limiting the reading of the RFID tags 831 of the game coins 83 in the placement areas 80a to 80e and the dealer area 90 by the reading antenna of the game coin tray 51. Therefore, in this embodiment, the reading antenna of the game coin tray 51 can read asynchronously at any time in the above-mentioned placement areas 80a to 80e and the dealer area 90. In addition, since the metal wire 6010 functions as a read-limiting antenna, when reading the placement areas 80a to 80e and the dealer area 90, these reading antennas can also be prevented from reading the RFID tags 831 of the game coins 83 of the game coin tray 51.

[0244] It should be noted that a woolen cloth can be attached to the inside of the metal wire 6010, and the outside of the metal wire 6010 can be used as a buffer. Thus, the metal wire 6010 can be provided as a decoration at the boundary between the buffer and the woolen cloth, and can be provided on the game table 6005 without any sense of incongruity. It should be noted that, on the basis of or in place of the metal wire 6010 that functions as such a read-limiting antenna, a shielding member for preventing interference in reading between the coin tray 51 and the placement areas 80a to 80e and the dealer area 90 can be provided.

[0245] As described above, if the gaming table reading system 100 according to the present embodiment is used, for RFID tags placed on the same plane as the gaming table surface, multiple reading antennas are configured in parallel with the plane, and the RFID tags are read separately at each position of the plane, so that it is possible to grasp the position of the RFID tag on the plane. In the gaming table, the placement object is determined according to the position of the game coin and the areas defining the placement object are arranged close to each other. Furthermore, in the gaming table, even if it is desired to shield the areas, such a shielding component cannot be set on the surface of the gaming table. Therefore, as shown in the present embodiment, a reading control antenna is appropriately configured to interfere with the reading of the reading antenna to read the reading area that should not be read, and the timing of the reading of the reading antenna and the reading control of the reading control antenna is appropriately controlled, so that even when multiple reading areas are densely packed, these multiple reading areas can be appropriately read separately.
