BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a game table apparatus that is used in a game arcade
such as a casino.
2. Description of Related Art
[0002] In a game which is played in a casino, such as a poker, a roulette and the like,
a chip functions as a game value element. Within the casino, a value of the chips
is equivalent to that of money. A player participates in a game by betting chips.
Each time one game is finished, a dealer pays out chips to respective players. At
this time, the dealer makes mental calculations a payout number of chips. Therefore,
the payout number of chips may be mistaken due to miscalculation.
[0003] Japanese Patent Unexamined Publication No. 2003-70956 discloses a card-game monitoring system and a card-game table, in which, for the
purpose of preventing a dealer from miscalculating, an IC tag storing therein identification
data about a value is buried in each chip and an identification data reader that reads
identification data of a chip value is provided in a bet region of a game table, which
is a region where each player places chips to be bet, so that the amounts of chips
bet by respective players are automatically calculated and displayed on a display
device. By checking the display device that is displaying the amounts of chips bet
by respective players, the dealer can correctly pay out chips.
SUMMARY OF THE INVENTION
[0004] In the card-game table disclosed in the above-mentioned document, the amount of chips
bet by each player is automatically calculated. However, the dealer has to calculate
by himself/herself the total amount of chips he/she holds. Therefore, it is troublesome
for the dealer to know increase and decrease in total amount of chips he/she holds,
that is, to know his/her win-or-lose status.
[0005] An object of the present invention is to provide a game table apparatus that enables
a dealer to easily know increase and decrease in a total amount of game value elements
he/she holds.
[0006] According to a first aspect of the present invention, there is provided a game table
apparatus comprising a game table, a first placement region, a first identification
data item reading means, a first calculating means, and a first display means. In
one area of the game table a dealer is located, and in the other area thereof a player
is located. The first placement region is provided in the one area of the game table
and for game value elements held by the dealer to be placed thereon. The first identification
data item reading means, through a wireless communication, reads an identification
data item from each of the game value elements placed on the first placement region.
Each of the game value elements stores therein its own identification data item. The
first calculating means calculates a total amount of the game value elements placed
on the first placement region based on the identification data items read by the first
identification data item reading means. The first display means displays, to the dealer,
the total amount of the game value elements calculated by the first calculating means.
[0007] In this aspect, identification data items of all game value elements placed on the
first placement region are read through the wireless communication, and then a total
amount of the game value elements is calculated and displayed on the first display
means. Accordingly, the dealer can know the total amount of the game value elements
he/she holds by seeing the first display means, without calculating it by himself/herself.
Therefore, the dealer can easily know increase and decrease in total amount of his/her
game value elements, that is, his/her win-or-lose status.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] In the following, a certain preferred embodiment of the present invention will be
described with reference to the accompanying drawings.
[0010] FIG. 1 illustrates a state where four game table apparatuses 10 according to an embodiment
of the present invention are connected to a center server 50 via a communication network
6. The game table apparatuses 10 are placed in a hall of a casino, while the center
server 50 is placed in a monitoring room of the casino. Each of the game table apparatuses
10 has a game table 27, a small monitor 13 that serves as a first display means, a
large monitor 17 that serves as a second display means, and a computer 11.
[0011] As shown in FIG. 2, the game table 27 has such a planar shape that its rear side
in the drawing is straight and its front side in the drawing is curved. Three players
(not shown) are positioned on the curved side of the game table 27 which is the front
side in the drawing, while one dealer 1 is positioned on the straight side of the
game table 27 which is the rear side in the drawing, so that a card game or the like
is played. Here, positions of the three left, center, and right players are defined
sequentially as seats A, B, and C. The number of players is not limited to three.
[0012] Three bet regions 29, in which the respective players places their chips to be bet
on a game, are defined on an upper face 27a of the game table 27. Each of the bet
regions 29 is provided with an identification data reader 19. The identification data
reader 19 is buried in the game table 27 and makes a wireless communication with a
chip 21 that is placed on the corresponding bet region 29, thereby contactlessly reading
identification data of the chip 21.
[0013] Three second placement regions 26, in which the respective players place chips 21
they hold, are defined on the upper face 27a of the game table 27. The three second
placement regions 26 locate closer to the players than the bet regions 29 are. Each
of the placement regions 26 is provided with an identification data reader 16 that
serves as a second identification data item reading means. The identification data
reader 16 is buried in the game table 27 and makes a wireless communication with a
chip 21 that is placed on the corresponding placement region 26, thereby contactlessly
reading identification data of the chip 21.
[0014] On the upper face 27a of the game table 27, a first placement region 25, in which
the dealer 1 places chips 21 he/she holds, is defined at the rear side in the drawing.
The placement region 25 is provided with an identification data reader 15 that functions
as a first identification data item reading means. The identification data reader
15 is buried in the game table 27 and makes a wireless communication with a chip 21
that is placed on the placement region 25, thereby contactlessly reading identification
data of the chip 21.
[0015] On the upper face 27a of the game table 27, a card case 30 that stores cards 9 therein
is provided at the rear side in the drawing, too. During a game, the dealer 1 takes
cards 9 out of the card case 30, and distributes the cards to the respective players
and to the dealer 1 himself/herself.
[0016] Referring to FIG. 1 again, identification data of chips 21, which have been read
by the respective identification data readers 15, 16, and 19, are transmitted to the
computer 11 in real time. Based on the identification data read by the identification
data reader 15, the computer 11 calculates a total amount of chips 21 that are placed
on the placement region 25, and displays it on a display screen 13a of the small monitor
13. It should be noted that placed on the placement region 25 are all of the chips
21 the dealer 1 holds.
[0017] Based on the identification data read by each of the identification data readers
16, the computer 11 calculates a total amount of chips 21 that are placed on each
of the placement regions 26. Then, the computer 11 displays, on a display screen 17a
of the large monitor 17, the total amounts of chips 21 that are placed on the respective
three placement regions 26 as a seat-A total amount, a seat-B total amount, and a
seat-C total amount, respectively. It should be noted that placed on the placement
regions 26 are all of the chips 21 the respective players hold.
[0018] Based on the identification data read by each of the identification data readers
19, the computer 11 calculates a total amount of chips 21 that are placed on each
of the bet regions 29 (hereinafter referred to as a bet amount). Then, the computer
11 displays, on the display screen 13a of the small monitor 13 and on the display
screen 17a of the large monitor 17, bet amounts corresponding to the three bet regions
29 as a seat-A bet amount, a seat-B bet amount, and a seat-C bet amount, respectively.
It should be noted that each player places all of the chips 21 he/she bets on a game
in each corresponding bet region 29.
[0019] The small monitor 13 is provided on a side face of the game table 27 with its display
screen 13a facing the dealer 1. Displayed on the display screen 13a are, as described
above, the total amount of dealer chips and the bet amounts of the respective players
(i.e., the seat-A bet amount, the seat-B bet amount, and the seat-C bet amount). When
paying out the chips 21, the dealer 1 checks the small monitor 13 for the bet amounts
of the respective players. This enables the dealer 1 to pay out the chips 21 quickly
and correctly.
[0020] The large monitor 17 (see FIG. 1) is provided behind the dealer 1 and away from the
game table 27, with its display screen 17a facing the players. The large monitor 17
is visible not only to the players who are playing a game on the corresponding game
table 27 but also to a large audience existing in the hall of the casino. Displayed
on the display screen 17a of the large monitor 17 are a background design 3d depicting
the game table 27, and split screens 3a, 3b, and 3c on a lower-left side, an under
side, and a lower-right side, respectively. The split screen 3a shows a total amount
of chips and a bet amount of a player who is sitting on the seat A. The split screen
3b shows a total amount of chips and a bet amount of a player who is sitting on the
seat B. The split screen 3c shows a total amount of chips and a bet amount of a player
who is sitting on the seat C. Like this, the display screen 17a is configured so as
to allow correspondence between the three split screens 3a to 3c and the players sitting
on the respective seats A to C to be clearly recognized.
[0021] Data on a total amount of chips of a dealer and data on a total amount of chips of
each player are transmitted from each game table apparatus 10 to the center server
50. A display device of the center server 50 displays thereon a display screen 50a
including split screens 4a, 4b, 4c, and 4d which respectively shows information about
first, second, third, and fourth tables. Here, the first to fourth tables mean the
respective game table apparatuses 10 placed in the hall of the casino, and correspond
to game table numbers which will be described later.
[0022] An observer who monitors the display device of the center server 50 can, by watching
the display screen 50a, know a status of a game which is played in each game table
27.
[0023] Next, with reference to FIG. 3, the chip 21 used as a game value element in a game
will be described in detail. FIG. 3 is a partial sectional view, showing a section
at its right half. As shown in FIG. 3, the chip 21 has a coin-like shape, and an IC
tag 23 and a transmitting antenna 22 are buried inside the chip 21.
[0024] An IC chip that stores therein identification data relating to a value of the chip
21, a tuning capacitor, a rectifier diode, a smoothing capacitor, etc. are incorporated
into the IC tag 23. The transmitting antenna 22 includes an antenna coil that is,
inside the chip 21, annularly wound several times. Elements of the IC tag 23 are connected
to both ends of the transmitting antenna. The number of windings of the transmitting
antenna 22, etc. is properly set depending on functions required.
[0025] The transmitting antenna 22 and the tuning capacitor of the IC tag 23 form a resonant
circuit. An induction field caused by mutual induction functions as a transmission
medium, and data are carried contactlessly by means of a wireless communication using
resonance due to electromagnetic waves. Through this wireless communication, identification
data relating to a value of the chip 21 which are stored in the IC chip is read by
the identification data reader 15, 16, or 19. The identification data reader 15 is
able to read identification data of all the chips 21, including piled-up ones, placed
on the placement region 25. The same is applied to the identification data readers
16 and 19, too. Induced electromotive force caused by mutual induction serves to supply
power necessary for operating the IC tag 23 and the transmitting antenna 22. The induced
electromotive force is generated by a flux change which occurs upon movement of the
chip 21 or data-reading by the identification data reader 15, 16, and 17.
[0026] The IC chip may store not only the identification data relating to a value of the
chip 21 but also data such as a serial number of the chip 21, a color of the chip
21 and the like.
[0027] Next, an electrical construction of the game table apparatus 10 will be described
with reference to FIG. 4.
[0028] The computer 11 which controls an operation of the game table apparatus 10 has an
interface circuit 34, an input/output bus 35, a CPU 31, a ROM 32, a RAM 33, a communication
interface circuit 37, and a display controller 36.
[0029] The input/output bus 35 is connected to the CPU 31, and inputs/outputs a data signal,
etc. to/from the CPU 31. The interface circuit 34 is connected to the input/output
bus 35.
[0030] The identification data readers 15, 16, and 19 are connected to the interface circuit
34. Each of the identification data readers 15, 16, and 19 has a receiving antenna
(not shown) and a receiver (not shown). The receiving antenna corresponds to the transmitting
antenna 22 of the chip 21. The receiver converts a signal received from the transmitting
antenna 22 into data and processes the data. As a modulation system, a common system
such as the ASK method may be adopted. Identification data of the chips 21 that have
been read by the identification data readers 15, 16, or 19 are inputted via the interface
circuit 34 into the input/output bus 35, and then processed by the CPU 31.
[0031] The ROM 32 and the RAM 33 are connected to the input/output bus 35. The ROM 32 stores
therein a control program, such as a main routine program, for a general control of
the game table apparatus 10. The RAM 33 temporarily stores therein various information
such as data about the number of chips 21 of each value. The various information relating
to the chips 21, which is temporarily stored in the RAM 33, is stored in the form
of a chip data table as will be described later.
[0032] The communication interface circuit 37 is connected to the input/output bus 35. The
communication interface circuit 37 is connected to the center server 50 via the communication
network 6. The communication interface circuit 37 is a circuit for communicating with
the center server 50, and functions as a connection means of the present invention.
[0033] The display controller 36 is connected to the input/output bus 35. Based on the chip
data table stored in the RAM 33, the display controller 36 generates drive signals
for driving the small monitor 13 and the large monitor 17, and outputs the drive signals
to the small monitor 13 and the large monitor 17, respectively. Thus, a total amount
of chips of the dealer and amounts of chips bet by respective players are displayed
on the display screen 13a of the small monitor 13, while total amounts of chips of
the respective players and the amounts of chips bet by the respective players are
displayed on the display screen 17a of the large monitor 17.
[0034] Next, the chip data table, which is stored in the RAM 33, is described with reference
to FIG. 5.
[0035] The chip data table has a $10 chip field, a $50 chip field, $100 chip field, a total
chip field, a bet amount field, and a total game field. Stored in the $10 chip field
are the number of $10 chips placed on the dealer's placement region 25, which have
been read by the identification data reader 15, and the number of $10 chips placed
on the placement regions 26 for the respective seats A, B and C, which have been read
by the three identification data readers 16. The same is applied to the $50 chip field
and the $100 chip field.
[0036] Stored in the total chip field is, with respect to each of the dealer, players sitting
on the seats A, B and C, the total amount of chips 21 the number of which is stored
in the $10 chip field, the $50 chip field, and the $100 chip field. Stored in the
bet amount field are the amounts of bets of respective players sitting on the seat
A, seat B, and the seat C, which have been read by the three identification data readers
19. Stored in the total game field is the total number of games that have been played
on the game table 27.
[0037] Next, a management table, which is stored in the center server, will be described
with reference to FIG. 6.
[0038] The management table has a game table number field, a $10 chip field, a $50 chip
field, a $100 chip field, a total chip field, and a total game field. The information
on the chip data table (see FIG. 5), more specifically the number of chips 21 of each
value, the total amount of chips, and the total number of games, is transmitted from
each game table apparatus 10, and stored in one-to-one correspondence with each game
table number. Here, the game table number means an identifier which has been in advance
assigned to each game table apparatus 10. The management table is updated at the timing
when one game ends based on a data processing routine of the game table apparatus
10 (see FIG. 8) and a data processing routine of the center server 50 (see FIG. 9)
which will be described later. Accordingly, the management table does not contain
information about the bet amount of each player. When no chips 21 have been placed
on the bet regions 29 of all player's seats for a predetermined period of time (ten
seconds in this embodiment), then it is determined that one game ends.
[0039] Next, a main routine of the game table apparatus 10 will be described with reference
to FIG. 7. Respective steps included in the main routine, which will be described
below, are executed by the CPU 31 (see FIG. 4).
[0040] First, the identification data reader 15 senses the dealer's placement region 25
(S1). The numbers of all chips 21 of the respective values that are placed on the
placement region 25 are registered in the $10 chip field, the $50 chip field, and
$100 chip field of the chip data table shown in FIG. 5 (S2). Then, the total amount
of chips of the dealer is calculated based on the number of all the chips 21 of each
value (S3), and registered in the total chip field of the chip data table (S4). Then,
the total amount of chips of the dealer is displayed on the small monitor 13 (S5).
[0041] Accordingly, the dealer 1 can know the total amount of chips 21 he/she holds by seeing
the small monitor 13, without calculating it by himself/herself. Therefore, the dealer
1 can easily know increase and decrease in total amount of his/her chips 21, that
is, his/her win-or-lose status.
[0042] Subsequently, a seat number "n" (where n is 1 to 3) is set to "1" (S6). Here, first,
second, and third seats are the seats A, B, and C, respectively. Then, the identification
data reader 19 senses the bet region 29 of the n-th seat (S7). The numbers of all
chips 21 of the respective values that are placed on the n-th seat bet region 29 are
stored in the RAM 33 (S8). Then, the identification data reader 16 senses the placement
region 26 of the n-th seat (S9) . The numbers of all chips 21 of the respective values
that are placed on the n-th seat placement region 26 are registered in the $10 chip
field, $50 chip field, and $100 chip field of the chip data table (S10) .
[0043] Then, whether the bet regions 29 and the placement regions 26 of all the player's
seats have been sensed or not is determined (S11). When it is determined that sensing
has not yet been made on the bet regions 29 and the placement regions 26 of all the
player's seats (S11: NO), "1" is added to "n" (S12) and the processing returns to
S7.
[0044] When it is determined that sensing has been made on the bet regions 29 and the placement
regions 26 of all the player's seats (S11: YES), the processing proceeds to S13 in
which the amount of bets in each seat is calculated based on data that have been stored
in RAM 33 in the previous step S8, and also in which the total amount of chips in
each seat is calculated based on the numbers of chips 21 of the respective values
that have been registered in the previous step S10. The amount of bets and the total
amount of chips thus calculated in S13 are, with respect to each seat, registered
in the bet amount field and the total chip field of the chip data table, respectively
(S14). Then, the amounts of bets in the respective player's seats are displayed on
the small monitor 13 (S15), while the total amounts of chips and the amounts of bets
in the respective player's seats are displayed on the large monitor 17 (S16). After
S16, the processing returns to S1.
[0045] This enables each player to know, by seeing the large monitor 17, the total amount
of chips 21 he/she holds without calculating it by himself/herself. Therefore, each
player can easily know increase and decrease in total amount of his/her chips 21,
that is, his/her win-or-lose status.
[0046] The large monitor 17 is visible to a large audience existing in the hall of the casino,
too. The audience is able to, even at a position remote from the game table 27, see
the large monitor 17 to know the total amount of chips and the amount of bets of each
player who is playing a game on the game table 27. Accordingly, there is little need
that the audience should gather around the game table 27. This can avoid making a
crowd around the game table 27. In addition, a player who is winning in a game can
feel high superiority because his/her winning is known even to a distant audience.
[0047] The CPU 31 of the computer 11 executes a data processing routine shown in FIG. 8,
independently of the main routine shown in FIG. 7.
[0048] First, a timer is reset (A1), and then started (A2). The identification data readers
19 sense the bet regions 29 of the respective player's seats (A3), and whether a chip
21 exists in any of the bet regions 29 is determined (A4) . When a chip 21 exists
in any of the bet regions 29 (A4: YES), it is determined that a gaming is being played,
and the processing returns to A1.
[0049] When a chip 21 does not exist in any of the bet regions 29 (A4: NO), whether a predetermined
period of time (ten seconds in this embodiment) has elapsed or not is determined based
on the timer (A5). When a predetermined period of time has not elapsed yet (A5: NO),
the processing returns to A3. When a predetermined period of time has elapsed (A5:
YES), it is determined that one game has ended. Thus, the total number of games, which
is stored in the chip data table in the RAM 33 (see FIG. 5), is counted up by "1"
(A6). Various information, except the amounts of bets, is acquired from the chip data
table (A7).
[0050] In A8, produced is an information signal including, in addition to the various information
acquired in A7, a game table number which is an identifier of the game table apparatus
10. The information signal is transmitted to the center server 50 via the communication
network 6 (A9). After A9, the processing returns to A1.
[0051] In the center server 50 which receives the information signal from each game table
apparatus 10, a data processing routine as shown in FIG. 9 is executed.
[0052] First, whether the information signal is received from any game table apparatus 10
or not is determined (B1). When the information signal is not received (B1: NO), the
processing returns to B1 in which the server 50 waits for the information signal to
be received. When the information signal is received (B1: YES), a game table number
that is included in the information signal is recognized (B2). In B3, various information
included in the information signal, more specifically the number of chips 21 of each
value, the total amount of chips, and the total number of games, is registered in
the fields of a corresponding game table number in the management table shown in FIG.
6. Then, the total amounts of chips of the dealer and of the respective players are
displayed on the display device of the center server 50 (B4). After B4, the processing
returns to B1.
[0053] Consequently, the observer who monitors the center server 50 can, by watching the
display screen 50a, check increase and decrease in total amount of chips 21 the dealer
1 holds, that is, whether the dealer 1 is winning or losing. Thus, in a case where
the dealer 1 is losing, the observer can surely give an instruction to change the
dealer 1 or instruct someone, for example a staff of the hall, to restock chips 21
for the dealer 1.
[0054] In the above-described embodiment, the small monitor 13 displays thereon the total
amount of chips of the dealer and the amount of bets of each player. However, it may
display thereon only the total amount of chips of the dealer, or alternatively it
may additionally display thereon the total amount of chips of each player. With such
a construction as well, the dealer 1 can, by checking the total amount of dealer's
chips, easily know increase and decrease in total amount of chips 21 he/she holds,
that is, his/her win-or-lose status.
[0055] In the above-described embodiment, the large monitor 17 displays thereon the total
amounts of chips and the amounts of bets of all players. However, it may also be possible
that only the total amounts of chips of all players are displayed thereon. With such
a construction as well, each player can, by checking the total amount of chips, easily
know increase and decrease in total amount of chips 21 he/she holds, that is, his/her
win-or-lose status.
[0056] While this invention has been described in conjunction with the specific embodiments
outlined above, it is evident that many alternatives, modifications and variations
will be apparent to those skilled in the art. Accordingly, the preferred embodiments
of the invention as set forth above are intended to be illustrative, not limiting.
Various changes may be made without departing from the spirit and scope of the invention
as defined in the following claims.
