Description

  The present invention relates to a coin, a game table, and a management system.

  Patent Documents 1 and 2 disclose a technique for detecting the placement state of casino chips. These documents include a table provided with an antenna for transmitting radio waves in the X direction of the table and an antenna for transmitting radio waves in the Y direction of the table in order to read information of the ID tag chip embedded in the casino chip. It is disclosed. Then, by transmitting radio waves in the X direction and the Y direction, radio waves due to flux are transmitted at points (cross points) where these radio waves intersect. Information on the ID tag chip embedded in the casino chip placed on the cross point is read by the radio wave generated by the flux, and the placement state of the casino chip is detected.

  Patent Document 3 discloses a table including a plurality of antennas for reading identification information from a game medium. In the technique of Patent Document 3, while transmitting the radio wave of one of the adjacent antennas while changing the output level, the transmission of the radio wave of the other antenna is stopped. And it is disclosed that the game media placed in the placement area is specified by collating the data read by each antenna.

  In the techniques of Patent Documents 1 and 2, there are cases where a casino chip placed on an adjacent cross point is erroneously detected due to diffusion of radio waves due to flux. In order to prevent this erroneous detection, it is necessary to suppress the output level of the radio wave. However, if the output level of radio waves is suppressed, information on the ID tag chip embedded in the casino chip cannot be read when a large number of casino chips are stacked.

  In the technique of Patent Document 3, the radio wave of one of the adjacent antennas is transmitted while changing the output level, and then the same processing is performed on the other antenna, and the read data is collated. It is necessary to do so, and it takes time to specify the position of the game medium placed in the placement area.

  Therefore, an object of the present invention is to provide a coin, a game table, and a management system that can quickly specify an accurate position of a coin on a game table.

  A coin according to an aspect of the present invention includes a receiving unit that receives positioning signals from a plurality of transmission sources, a determining unit that determines a position based on the positioning signal, and an output unit that outputs position information indicating the position. Prepare.

<Explanation of terms>
In this specification, terms are defined as follows.
“Game table”: A table on which various games are played in a game hall. Generally, one dealer is assigned to one table. In addition, a plurality of users can participate in the game simultaneously per table.
“Dealer”: A person on the playground side that controls the progress of the game, such as distributing cards used in the game.
"User": A guest person who comes to the game hall and participates in the game.
“Roulette”: A game in which a dealer throws a ball into a rotating disk and the user predicts where the ball will fall. There are various types of items to bet, such as red or black, bet that includes a plurality of numbers such as odd or even, and bet on a specific number.
“Baccarat”: A traditional card game in which a user predicts and wins a card game by a bunker (body role) and a player (customer role). Users simply expect the game to win or lose and are gaining popularity at casinos around the world due to their ease of use. The dealer distributes 2 to 3 playing cards to each of the bunker and player according to a certain rule, and the first digit of the total number distributed is closer to “9”.
“Coin”: a medium used when participating in a game. Also called a chip. Although a circular thing is common, what kind of shape may be sufficient. The size may be any size.
“Bet” means that a user bets by expressing his / her expectation. For example, in roulette, it means that the user predicts where a ball falls on the rotating disk and bets on the expected destination. In Baccarat, a bet is made in anticipation of whether a bunker wins, a player wins, or a match ends in a draw (Tie), and the player wins or loses.
“Bet amount”: an amount used for betting. Each user can arbitrarily specify the bet amount by placing a desired type and number of coins on the game table. When the user's prediction is won, a payout corresponding to the bet amount is obtained.
“BET AREA”: An area where the user asserts the bet amount by placing a coin. That is, it is an area where the user bets coins. For example, in the roulette, a number existing on the turntable, an item including a plurality of numbers (for example, “RED” including the number of red frames), and the like are clearly indicated on the table as bet areas. Further, the boundary portion between the numbers described on the table is also a bet area. When a bet is placed on the boundary between numbers, these numbers are treated as a lump of bets. In Baccarat, a region for betting according to whether a bunker wins, a player wins, or a match ends in a draw is clearly shown on the table.
“Credit”: A balance held by the user. If a dividend is obtained, the amount of credit increases, and if it is not expected, the amount of credit decreases.

<Advantages of specifying the coin position>
First, an advantage of specifying the position of a coin in a game table in a game hall such as a casino will be described.

  During the game, coins move from place to place on the gaming table. For example, generally, in a game table, a coin storage unit for storing user coins and a payout coin storage unit for storing dealer payout coins are installed. When the game starts, the user takes out a coin of a desired amount from the coins stored in the coin storage unit, and places it in a predetermined bet area. As a result, the item betted by the user (hereinafter referred to as “betting destination”) and the bet amount are determined. As a result of the game, the dealer takes out coins corresponding to the payout for the user who has bet on the betting destination who has won the game, that is, the user who has made a prediction, from the payout coin storage unit. Then, a payout coin is paid to the user who has hit the prediction. Coins bet by an unexpected user are collected by the dealer and stored in the payout coin storage unit.

  In this way, during the period in which the game is being played, the coins change from one position to another on the gaming table. If the position of such a coin can be specified on the management system side that manages the game hall, various advantages appear. For example, the management system side can specify the user's betting destination and betting amount. The management system is a system managed by an operator who operates the amusement hall. Details will be described later. If the user's betting destination and betting amount are known, the amount of coins to be paid can be specified on the management system side based on the result of the game. Therefore, when the amount of coins that the dealer pays to the user is different from the amount specified on the management system side, it is possible to prevent the dealer from being fraudulent or mistaken by notifying a warning or the like.

<Example of game table>
FIG. 1 is a diagram illustrating an example of a game table 10 according to the present embodiment. In the game table 10, transmission sources 15a, 15b, and 15c are installed. The transmission sources 15a, 15b, and 15c are collectively referred to as the transmission source 15. The transmission source 15 is a transmitter that transmits a positioning signal. In the present embodiment, the coin 20 receives the positioning signal transmitted from the transmission source 15 and determines the position of the coin 20 based on the received positioning signal. In the example shown in FIG. 1, an example in which three transmission sources 15 are installed at different positions on the game table 10 is shown, but the present invention is not limited to this. The number of transmission sources 15 may be four or more. Further, the transmission source 15 does not need to be installed on the game table 10 and may be installed at an arbitrary position in the game hall such as a ceiling, a floor, and a wall near the game table 10. In addition, when there are a plurality of game tables 10 in the game hall, the transmission sources 15a to 15c may be installed in each table (or in the vicinity of each table), respectively, or the transmission sources 15a to 15c are a plurality of tables. One set of may be shared.

  When positioning signals from the three transmission sources 15a to 15c are used, the position of the receiver can be calculated from each transmission source by the three-point intersection method. The distance D1 from the transmission source 15a to the coin 20 can be specified by the arrival time until the positioning signal transmitted from the transmission source 15a is received by the coin 20 as a receiver. That is, it can be seen that the coin 20 is located on one of the surfaces of the sphere having the radius D1 with the transmission source 15a as the center. Similarly, the distance D2 from the transmission source 15b to the coin 20 can be specified by the arrival time until the positioning signal transmitted from the transmission source 15b is received by the coin 20, and the sphere having the radius D2 with the transmission source 15b as the center. It can be seen that the coin 20 is located on any of the surfaces. Similarly, the distance D3 from the transmission source 15c to the coin 20 can be specified by the arrival time until the positioning signal transmitted from the transmission source 15c is received by the coin 20, and a sphere having a radius D3 centered on the transmission source 15c. It can be seen that the coin 20 is located on any of the surfaces. It can be specified that the intersection of the surfaces of these three spheres is the position of the coin 20.

  As an example, the transmission source 15 may be configured as a transmitter used in an indoor position information acquisition system called IMES (Indoor MEssaging System). The transmission source 15 transmits a positioning signal indicating a position where the transmission source 15 is installed. For example, the transmission source 15 may transmit a positioning signal using sound waves, may transmit using radio waves, or may transmit using light.

  The game table 10 includes coin storage units 16 a to 16 e and a payout coin storage unit 18. In addition, the game table 10 is provided with a card shoe 17 that accommodates a card to be distributed, an area 19a where a card is placed, and a bet area 19b.

<Coin block diagram>
FIG. 2 is a diagram illustrating a block of the coin 20 according to the present embodiment. The coin 20 includes a receiving unit 21, a determining unit 22, an output unit 23, and a charging unit 24.

  The receiving unit 21 includes a receiving IC. The receiving unit 21 of the present embodiment receives positioning signals from a plurality of transmission sources 15. The receiving unit 21 outputs each received positioning signal to the determining unit 22. When the transmission source 15 uses sound waves, the reception unit 21 can receive a positioning signal using an ultrasonic sensor (microphone) included in the reception IC. When the transmission source 15 uses light, the receiving unit 21 can receive a positioning signal using an IR sensor (photo sensor) included in the receiving IC. When the transmission source 15 uses radio waves, the receiving unit 21 can receive a positioning signal using an antenna (not shown) that receives radio waves.

  Here, the transmission sources 15a to 15c may transmit positioning signals using the same type of signals (for example, sound waves), and some of the transmission sources 15a to 15c (for example, the transmission source 15b) A positioning signal may be transmitted using a signal of a different type from other transmission sources (for example, transmission sources 15a and 15c) (for example, transmission sources 15a and 15c are sound waves and transmission source 15b is radio waves). In this case, a plurality of receiving units 21 corresponding to the type of signal transmitted from the transmission source may be provided in one coin 20.

  The determination unit 22 is a determination unit that includes a CPU (Central Processing Unit) and other memories, interfaces, and the like (not shown). The determining unit 22 determines the position of the coin 20 based on each positioning signal output from the receiving unit 21. The process of the determination part 22 is mentioned later.

  The output unit 23 includes an output IC. The output unit 23 converts the position information indicating the position determined by the determination unit 22 into a radio signal and outputs the radio signal to the management device. The output unit 23 also outputs the identification information of the coin 20 when outputting the position information to the management device. For example, the output unit 23 writes the position information in an output IC that functions as an RFID (Radio-Frequency IDentification) tag. This information can be read by an RFID reader (not shown) installed on the game table 10. That is, radio waves may be radiated from an antenna of an RFID reader (not shown) installed on the game table 10 to read position information written on the RFID tag. The output unit 23 includes a coil 23a that also functions as an antenna. The output unit 23 receives a radio wave from the antenna of the RFID reader, activates the output IC using the received radio wave as an electromotive force, and is written to the RFID tag. Send location information. The RFID reader receives the position information thus transmitted and transmits it to the management apparatus. Alternatively, the output unit 23 may transmit the position information to the management device using radio waves in a frequency band such as 2.4 GHz or 5 GHz used in a wireless LAN. The management device is a management device 550 included in the management system 500 described later with reference to FIG. 5, and is a device that manages position information of each coin 20. Details of the management device 550 will be described later.

  Charging unit 24 includes a charging IC. The charging unit 24 supplies power to the receiving unit 21, the determining unit 22, and the output unit 23. For example, the game table 10 is provided with a supply unit 511 (see FIG. 5 described later) for supplying power. The charging unit 24 can receive power from the supply unit 511 in a non-contact manner. For example, in this embodiment, power can be supplied by an electromagnetic induction method. In the game table 10, a power transmission coil (not shown) that functions as the supply unit 511 is embedded in a specific area such as a betting area. When the coin 20 is placed in this specific region and a current is passed through the power transmission coil, the magnetic field changes, and a current flows through the power receiving coil 24a of the charging unit 24. The place where the coil for power transmission is embedded may be the coin accommodating portions 16a to 16e or the payout coin accommodating portion 18.

<Determine coin position>
Next, an example of processing for determining the position of the coin 20 performed by the determination unit 22 will be described.

  FIG. 3 is a diagram showing an example of positions determined on the game table 10. In FIG. 3, description will be made assuming that a position on the game table 10 is specified by a row specified by an alphabet and a column specified by a number. For example, the coin 20 in FIG. 3 is identified as being placed at the position indicated by “section 6D”. Note that FIG. 3 shows an example in which each section is set widely for ease of explanation. Actually, it is possible to set a section in a smaller range than the section shown in FIG.

  The determination unit 22 determines the position of the coin 20 based on the transmission signals from the plurality of transmission sources 15 received by the reception unit 21. This will be specifically described below.

  For example, the transmission source 15 may transmit a positioning signal including position information indicating the position where the transmission source 15 is installed. In this case, the timing until the positioning signal sent from the transmission sources 15 a, 15 b, and 15 c is received by the coin 20 varies depending on the position of the coin 20. For example, a positioning signal transmitted from the transmission source 15a is received by the receiving unit 21 after 0.004 seconds have elapsed, and a positioning signal transmitted from the transmission source 15b is received by the receiving unit 21 after 0.005 seconds have elapsed. The positioning signal transmitted from 15c may be received by the receiving unit 21 after 0.006 seconds have elapsed. The determining unit 22 can determine the position of the coin 20 based on the difference in arrival time of these positioning signals and the position where the transmission source 15 is installed. The process for determining the current position based on the difference in arrival time of the positioning signal and the position of the transmission source uses the same technology as the three-point surveying method widely used in GPS (Global Positioning System), for example. Can be used.

  If the position of the coin 20 is determined by the three-point survey method in this way, the position of the upper coin can be appropriately determined even when, for example, a plurality of coins are stacked and a bet is placed. . Further, even if coins 20 are placed in adjacent subdivided sections, the positions of both coins 20 can be determined at the same timing. That is, there is no need to perform processing such as waiting for the stop of the transmission of the radio wave of the antenna provided in the other section and then transmitting the radio wave of the antenna provided in the other section.

  The transmission source 15 may transmit a positioning signal at the same timing synchronized with each other. Or the time information which recorded the time which transmitted the positioning signal may be contained in the positioning signal.

  Further, the transmission sources 15a, 15b, and 15c may be configured to transmit positioning signals having different wavelengths and different frequencies. In this case, the determining unit 22 of the coin 20 previously stores information on wavelengths and frequencies used by the respective transmission sources 15a, 15b, and 15c in a register and a memory (not shown), and the transmission sources 15a, 15b, and 15c. Information on the installed location is stored. Then, by analyzing the wavelength and frequency of the positioning signal of the transmission source 15, it is possible to specify which of the transmission sources 15a, 15b, and 15c is the positioning signal. As described above, the position of the coin 20 can be determined based on the difference in arrival time of the positioning signal and the position where the transmission source 15 is installed. The determination unit 22 can perform analysis according to the signal type of the transmission source 15. For example, when sound waves are used, the frequency of sound waves is specified. When light is used, the wavelength of light is specified. When radio waves are used, the frequency of electromagnetic waves is specified. Can be identified.

  The position information thus determined includes latitude, longitude, and height. The position information is output from the output unit 23 to the management device 550. In the management device 550, the positional relationship between the transmission source 15 and the game table 10 and the partition ratio on the table surface of the game table 10 are managed. For example, the management device 550 manages the latitude, longitude, and height information for each section on the table surface of the game table 10. The management device 550 determines the position where the coin 20 is present on the game table 10 based on the managed positional relationship information and the positional information output from the coin 20 (in the example of FIG. 3, the section 6D). ) Can be determined. That is, the position of the coin 20 on the game table 10 can be determined.

  In addition, when the positional relationship between the transmission source 15 and the game table 10 and the partition allocation information on the table surface of the game table 10 are stored in a register or a memory (not shown) of the coin 20, the determination unit 22 The position of the coin 20 can be determined as position information on the game table 10. In other words, in the example of FIG. 3, the determination unit 22 can determine the position indicating “section 6 </ b> D” on the game table 10 as the position of the coin 20.

  Thus, the determination unit 22 of the coin 20 may determine the latitude, longitude, and height at which the coin 20 is located, or may determine the position of the coin 20 on the game table (for example, the section 6D). .

<Coin operation flow>
FIG. 4 is a diagram showing an example of a flowchart showing the operation of the coin 20. In the example illustrated in FIG. 4, an example in which the coin 20 outputs position information from when the bet time (BET TIME) starts to when it ends is described.

  In step S410, the receiving unit 21 of the coin 20 receives a start signal indicating the start of the bet time. The receiving unit 21 may receive a special signal (start signal) from the transmission source 15 or may receive a start signal from the management device 550.

  In step S420, the receiving unit 21 determines whether an end signal indicating the end of the bet time has been received. If received, the process proceeds to step S480. Otherwise, the process proceeds to step S430.

  In step S430, the charging unit 24 determines whether the battery is insufficient. If it is insufficient, the process proceeds to step S440 and the battery is charged. The charging unit 24 can receive power from the supply unit 511 in a non-contact manner. Thereafter, the process proceeds to step S450. If the battery is not insufficient, the process proceeds to step S450.

  In step S450, the receiving unit 21 receives the positioning signal transmitted from the transmission source 15.

  In step S460, the determination unit 22 determines the position of the coin 20 based on the positioning signal received in step S450.

  In step S470, the output unit 23 outputs the position information of the position determined in step S460 to the management apparatus 550.

  The processing from step S430 to step S470 is repeated until an end signal indicating the end of the bet time is received. During the betting period, the position of the coin 20 is changed as appropriate by the user. The coin 20 outputs the appropriately changed position to the management device 550.

  When the receiving unit 21 receives an end signal indicating the end of the betting time in step S420, the process proceeds to step S480.

  In step S480, the determination unit 22 generates position information determination data. The position information confirmation data is data indicating that the position is confirmed.

  In step S490, the output unit 23 outputs the position information confirmation data generated in step S480 to the management device 550.

  According to such a process, when the betting time ends, the position of the coin 20 managed by the management device 550 becomes the confirmed position.

  Note that the above-described processing is merely an example, and the present invention is not limited to this. For example, when the betting time is ended, the position information confirmation data is output. However, the present invention is not limited to this. According to the processing from step S430 to step S470, the position of the coin 20 is appropriately output to the management device 550. Therefore, when the betting time is over, the management device 550 determines that the betting time has ended, and the management device 550 uses the position information sent from each coin 20 at that time to allow the management device 550 to The form which specifies a position may be sufficient.

  In FIG. 4, the example in which the coin 20 outputs the position information from the start to the end of the bet time has been described. However, the present invention is not limited to this. Regardless of the bet time, the coin 20 may be output in position information.

<System configuration>
FIG. 5 is a block diagram illustrating an example of the configuration of the management system 500 according to the present embodiment. .

  The management system 500 includes a game table 10, a coin 20, a transmission source 15, a management device 550, a management database (DB) 560, and a coin position database (DB) 561.

  The management device 550 includes an acquisition unit 551, a specification unit 552, and a notification unit 553. The management device 550 reads and writes information between the management DB 560 and the coin position DB 561. The management DB 560 is a database server that manages information such as coin holder information, user credit information, and progress information of various games performed at the game hall. The coin position DB 561 is a database server that manages the position of the coin 20 on the game table 10. The management device 550, the management DB 560, and the coin position DB 561 can each be realized as an information processing device. The information processing apparatus may include a CPU, memory, HDD, and network interface (not shown). Each unit of the management apparatus 550 in FIG. 5 temporarily reads a program stored in the HDD into the memory, and the CPU executes the program read into the memory so that the CPU executes the program of the management apparatus 550 in FIG. It may function as each part. 5 may be realized by a plurality of information processing apparatuses connected to each other through various networks. Further, at least a part of each unit of the management device 550 of FIG. 5 may be realized by distributed processing by a plurality of information processing devices. Moreover, although the management apparatus 550, management DB560, and coin position DB561 are illustrated as separate structures, these may be provided in the same apparatus.

  Here, an example in which the management device 550 is provided for each game table 10 will be described. That is, the game table 10 can include a management device 550 including an acquisition unit 551, a specification unit 552, and a notification unit 553. Note that the management device 550 may be provided for each of the plurality of game tables 10, or one management device 550 may be provided for the entire game hall.

  The acquisition unit 551 acquires the position information output from the coin 20 and the identification information of the coin 20.

  The specifying unit 552 can specify the position where the coin 20 is placed on the game table 10 based on the position information acquired by the acquiring unit 551. The specifying unit 552 compares the latitude, longitude, and height included in the position information with the latitude, longitude, and height for each section on the table surface of the game table 10 and determines the position of the coin 20 on the game table 10. The position indicating the section (for example, “section 6D”) is specified. Further, the specifying unit 552 can specify the amount associated with the coin 20 based on the identification information of the coin 20 acquired by the acquiring unit 551. Further, the specifying unit 552 can specify the user who holds the coin 20 based on the identification information of the coin 20.

  As described above, the specifying unit 552 uses the position information of the coin 20 acquired from the coin 20 and the identification information of the coin 20, so that the user who holds the coin 20, the bet destination of the coin 20, and the coin 20 Twenty bet amounts can be specified. When a plurality of coins 20 are placed, the bet amount is the total amount.

  When the specifying unit 552 cannot specify the position, the notification unit 553 notifies an error. There are various error notification methods. For example, the error may be in a form in which an error message is displayed on a display unit (not shown) provided in the game table 10. The display unit may be provided on the dealer side, may be provided on the user side, or may be used by both for confirmation. Further, as an example of an error display, a message notifying that the position of the coin cannot be specified or that the coin is placed at a position where betting is impossible may be used. Alternatively, a warning lamp (not shown) provided in the game table 10 may be turned on, or sound, sound effects, etc. may be output from a speaker (not shown). Moreover, you may vibrate the table and the chair where the user is sitting.

  In this embodiment, it is useful to notify an error. When a bet is placed in a confusing place, there is a possibility that the bet destination intended by the user and the information updated in the management device 550 or the management DB 560 are different. Therefore, when the position cannot be specified by the specifying unit 552, an error is notified to prevent a bet from being placed in a confusing place.

<Game progress example>
FIG. 6 is a diagram showing an example of coin position information 600 managed by the coin position DB 561. FIG. 7 is a diagram illustrating an example of coin management information 710, credit management information 720, and game progress management information 730 managed by the management DB 560. An example of processing when a game is played with coins actually placed on the game table 10 will be described with reference to FIGS. 3, 6, and 7.

  In the following, a user whose user ID is “U301” (hereinafter, a user to whom U301 is assigned as a user ID will be referred to as “user U301” or the like) is seated at the game table 10 for playing a baccarat game. Explain that it participates in. User U301 registers credits in advance with a cashier (not shown). In the credit management information 720, a user ID and a credit held by the user are managed.

  Further, the user U301 receives coins in advance at the cashier. Alternatively, the dealer of the game table 10 may distribute coins to the user U301. In any form, information that “the coin holder is the user U301” is managed as indicated by the coin management information 710. That is, it can be said that the coin owned by the user U301 is a coin dedicated to the user U301. In the coin management information 710, for each piece of coin identification information, the amount associated with the coin and the user of the coin holder are managed.

  In such a state, a betting period starts in the game table 10. Assume that the user U301 selects BANKER as the bet destination and decides to bet $ 30 as the bet amount. The user U301 places 30 dollar coins in the BANKER betting area. This placed coin determines its own position based on the positioning signal from the transmission source 15 as described above. Then, the position determined by the coin is sent to the management apparatus 550. The specifying unit 552 of the management device 550 specifies the position of the coin on the game table 10 based on the position sent from the coin. Then, as in the coin position information 600, information indicating where each coin exists is updated as appropriate.

  Thereafter, when the betting time ends and the position determination data is received, the management device 550 refers to the coin position information 600 and identifies which coin is present at which position. Then, the game progress management information 730 is updated with reference to the coin position information 600 and the coin management information 710. For example, the specifying unit 552 specifies that the coin identified by the coin identification information C111, C112, and C113 is present at the position D6 on the game table 10. The identifying unit 552 identifies that the holder of those coins is the user U301 and the total amount of those coins is 30 dollars with reference to the coin management information 710. The specifying unit 552 specifies that the position of D6 on the game table 10 is a BANKER betting area with reference to DB information (not shown). Then, as shown in the game progress management information 730, the specifying unit 552 records that the user U301 has placed a bet of $ 30 on BANKER. As shown in FIG. 7, since a game is played for each game table, the game progress management information 730 shows an example including information on each game table.

  Thereafter, it is assumed that a game is played and PLAYER wins, that is, the user U301 is not expected. Note that the result of such a game may be specified by, for example, reading information on a card placed on a table, or may be manually input from a dealer or the like. In this example, since the user U301 is not expected, in the game progress management information 730, the amount to be updated by the user U301 is minus $ 30. The credit amount of the user U301 in the credit management information 720 is updated with the amount to be updated.

  Thus, if the position of the coin 20 can be specified, the management device 550 can manage and update the user's credit as appropriate in conjunction with the game progress information.

<Example of providing an offset>
Next, a configuration for reducing variations in coin positions when a plurality of coins are mixed will be described. On the game table 10, a large amount of coins 20 are used in the game. Some coins 20 have different sizes and shapes depending on their types. On the other hand, in the case of a roulette, for example, the coin 20 is placed in a narrow section. When placed in a narrow section, depending on the type and placement of coins, it may be determined that the coin is placed in a position different from the originally intended location. This will be specifically described below.

  FIG. 8 is a diagram illustrating an example in which the receiving unit 21 of the coin 20 is provided on the outer periphery of the coin 20. There are various places where the receiving unit 21 is provided in the coin 20. In some cases, it may be provided near the center of the coin 20, and in other cases, it may be provided on the outer periphery of the coin 20 as shown in FIG. 8. Since the determination unit 22 determines the position based on the positioning signal received by the reception unit 21, for example, when the position of the reception unit 21 is provided in the central portion 27 of the coin 20, In the case where it is provided, a deviation of the distance 8d will occur.

  Further, even when the receiving unit 21 uses the same type of coin provided at the same position on the outer peripheral portion, a positional shift occurs. For example, when coins are stacked, the coins are not necessarily stacked so as to match the position of the receiving unit 21. When the position of the stacked coin receiving unit 21 is directly opposite the center of the coin, the position corresponding to one coin is placed even though the coin is stacked on the same table. This will cause a deviation. In addition, in the case where coins 20 having different sizes are mixed, this deviation may be further increased.

  In the present embodiment, the determination unit 22 determines the position (the center part 27 in FIG. 8) determined as the center point of the coin 20 as the position of the coin 20. In this way, by sharing a point that serves as a reference for determining the position of each coin 20, variation in position information determined by the coin 20 can be reduced.

  Specifically, an offset between the position of the receiving unit 21 of the coin 20 and the position of the central part 27 of the coin 20 is obtained in advance. This offset is a vector 8v from the position of the receiving unit 21 to the central portion 27. Then, the determination unit 22 adds the previously obtained offset to the determined position. By performing the processing in this way, the position of the coin 20 is determined as the position of the central portion 27. For example, in the example of FIG. 8, the first position determined by the determination unit 22 first is not the position of the center portion 27 but the position where the reception unit 21 is provided. The determination unit 22 determines the position of the coin 20 from the first position in consideration of the vector 8v with respect to the second position that is the position of the central portion 27 of the coin. That is, the determination unit 22 can determine the position of the coin 20 based on the relative positional relationship between the position where the receiving unit 21 is provided and the position of the central portion 27 of the coin 20.

  It should be noted that the distance 8d from the receiving unit 21 to the central portion 27 may be obtained by measuring in advance. The direction from the receiving unit 21 to the central unit 27 when a coin is placed may be specified by various methods. For example, a weak radio wave may be output from the reception unit 21 and the determination unit 22 may detect and specify the direction of the radio wave. In addition, any method may be used.

  With this configuration, the position determined by the coin 20 is the position of the central portion 27 of the coin 20, and thus variation in position information determined by each coin 20 can be reduced.

<Effective area where betting is possible>
Next, an area where a bet can be placed, that is, an effective area where a coin can be placed will be described.

  FIG. 9 is a diagram illustrating an effective area where coins can be placed. FIG. 9 is an enlarged view of a part of the roulette betting area. The notation 911 is a notation indicating that the area is a bet on the number “18”, and the notation 912 is an notation indicating that the area is a bet on the number “19”. Line 910 is a boundary line. In the case of roulette, placing a coin on this line 910 places a bet on both the numbers “18” and “19”. That is, a bet is made with the numbers “18” and “19” as a group of bets. In such a case, if the coin is placed slightly off the right side of the line 910, for example, whether the bet is placed on the number “19” alone, or both the numbers “18” and “19” are bet. It is unclear whether they are present.

  Therefore, in the present embodiment, an effective area 950 where betting is possible is provided. The effective area 950 is managed by the management device 550 in association with position information (section) on the table, for example.

  When the coin is located inside the valid area 950, the specifying unit 552 treats the bet as valid, and when the coin is located outside the valid area 950, treats the bet as invalid. If the bet is not valid, the notification unit 553 outputs an error.

  In the present embodiment, as described above, the determination unit 22 can determine the position of the coin as the position of the central portion 27 of the coin. When a part of a region within a predetermined range (specifically, radius) from the central portion 27 is located outside the effective region 950, the notification unit 553 outputs an error. In the example of FIG. 9, the coin 20 b has the central portion 27 b located on the line 910 and is within the effective area 950. On the other hand, in the coin 20c, the central portion 27c is shifted to the right side of the line 910, and as a result, a part of the region is located outside the effective region 950. Therefore, the notification unit 553 outputs an error.

<Effective height position>
Next, the height position where the bet is effective will be described.

  FIG. 10 is a diagram for explaining an effective height position when the coin 20 is placed on the game table 10. In the present embodiment, the position determined by the determination unit 22 is a position that also includes height information. When a game is actually played, a coin may fall under the table of the game table 10 like the coin 20f. At this time, if power remains in the coin charging unit 24 and the coin 20f is directly under the betable effective area, an inappropriate bet is placed on the management device 550 side. As a result, inconsistency occurs between the information managed by the management apparatus 550 and the amount of money recognized by the user. Therefore, the specifying unit 552 stores the height of the table surface 12 of the game table 10 in advance, and uses the identification information of one or more coins within a predetermined range 10h from the height to determine the coin amount. Identify. That is, the identifying unit 552 does not have to treat coins that transmit position information outside the predetermined range 10 h from the height of the table surface 12 as valid coins. Alternatively, the notification unit 553 may notify an error when there is a coin that is not within the predetermined range 10 h from the table surface 12 of the game table 10.

  According to such processing, when there is a coin 20 that does not exist within a predetermined height range on the game table 10, an error is notified, so that inconsistency with information managed by the management device 550 is prevented. be able to.

<Other embodiments>
In the embodiment described above, the example in which the amount of coins located in the betting area is specified has been described. However, according to the processing of the embodiment described above, not only the betting area but also the coin amounts stored in the coin storage units 16a to 16e that store user's coins and the payout coin storage unit 18 are specified. It is also possible to do. Therefore, when the game ends, the total amount of coins stored in the coin storage units 16a to 16e is compared with the user's credit managed by the credit management information 720. A mode in which 553 outputs an error may be adopted.

  Further, according to the embodiment described above, for example, a sheet on which a betting area on the table surface of the game table 10 is described can be exchanged according to a game. For example, it is also possible to exchange a baccarat sheet, which is a card game, and a blackjack sheet. Then, a positional relationship such as a bet area and an effective area corresponding to the exchanged sheet game is set in the management device 550. As a result, it is possible to divert and use the game table 10 for a plurality of types of games. That is, it becomes possible to provide the game table 10 with high versatility.
