Description

Technical Field

[0001] The present invention relates to a table game system having a security function in a card game such as baccarat using playing cards (hereinafter simply referred to as cards).

Background Art

[0002] In various playing games such as poker, baccarat, bridge, or blackjack, a dealer sets one deck or multiple decks of playing cards in a card shuffler or the like, and then deals the cards one by one to the game participants. At this time, in order to ensure the fairness of the game, it is necessary to deal those cards randomly. Therefore, the game organizer must shuffle the playing cards sufficiently randomly before setting them in the card shuffler so that the arrangements of the playing cards are different from each other. The shuffled playing cards used in various playing games such as poker, baccarat, bridge, or blackjack usually consist of 416 cards if there are 8 decks.

[0003] A conventional card shuffling device for shuffling cards is disclosed, for example, in Patent Document 1. As a result of being shuffled by the shuffling device, the shuffled playing cards are provided in individually unique card sequences, and individually identifiable shuffling card IDs are attached to the packaging or the like as barcodes.

Modes for Carrying Out the Invention

[0010] The following describes an embodiment of the table game system of the present invention. FIG. 1 is a perspective view showing an overall outline of the table game system of the present embodiment. FIG. 2 is a perspective view of the shuffle playing card used in the table game system of the present embodiment. In the table game system of the present embodiment, the shuffle playing card 1s is packaged, but when used in the game, it is stored in the card shooter device 2 in a state where the packaging is removed, and the cards 1 of the shuffle playing card 1s can be distributed one by one. During the game, the cards 1 are distributed by the dealer from the card shooter device 2 to the game table. The shuffle playing card 1s is shuffled so that the cards 1 constituting a predetermined number of decks (usually 6, 8, or 10 decks) are in a random order and are packaged in an individually unique card order, and an individually identifiable shuffle card ID is attached to the packaging box 4 by a barcode 3 (as an ID code).

[0011] As shown in FIG. 2, the packaging box 4 of the shuffle playing card 1s has a rectangular parallelepiped shape so as to wrap the entire circumference of the shuffle playing card 1s in the assembled state. The packaging box 4 is provided with zippers 5 in the form of zipper-like cut lines at two locations at a predetermined interval parallel to the longitudinal direction of the rectangular parallelepiped shape, and a central band 6 is provided in the central portion partitioned by the two zippers 5. The central band 6 is colored so as to be easily distinguishable from other parts (coloring is omitted in FIG. 2). By removing the two zippers 5 along the cut lines, the left and right side surfaces of the packaging box 4 are each removed, and both side surfaces of the shuffle playing card 1s can be exposed (the state of FIG. 1). As shown in FIG. 2, the order (1) to (3) of removing the zipper 5 is printed (indicated by the circled numbers) on each zipper 5.

[0012] Before the shuffling playing cards 1s are set in the card shooter device 2, a cut card 1c is inserted. The cut card 1c is inserted into the latter half of the shuffling playing cards 1s (about one-fourth or one-fifth of the remainder) when using the shuffling playing cards 1s in the game. The cut card 1c is used to prevent the ranks of each card 1 distributed during the game from being counted by players or the like and the ranks of the remaining few cards from being predicted, and to end the game on the game table with about 20 to 40 cards 1 remaining in the card shooter device 2. Usually, when the cut card 1c is drawn, after that game or after several games, the use of the shuffling playing cards 1s in use ends and the game ends. The shuffling playing cards 1s of the card shooter device 2 are replaced with new ones and a new game starts.

[0013] In FIG. 1, in the table game system of the present embodiment, cards 1 constituting a predetermined number of decks are shuffled and provided in an individual unique card arrangement, and a shuffling playing card 1s with an individually identifiable shuffling card ID attached as a barcode 3, and a barcode reader 100 or input means 200 capable of identifying the shuffling card ID, which houses the shuffling playing cards 1s and manually distributes the stored cards 1 one by one to the game table. It is a table game system comprising a card shooter device 2.

[0014] In FIG. 3, the card shooter device 2 of the embodiment of the table game system of the present invention is provided with a lid 2f that enables the insertion and removal of the shuffling playing cards 1s, and a sensor S for detecting the opening and closing of the lid 2f is provided under the lid 2f to detect the opening and closing of the lid 2f and detect that the shuffling playing cards 1s have been replaced. Furthermore, the card shooter device 2 is a card collection A card guide unit 7 that guides the cards 1 manually taken out one by one from the card storage unit 2C toward the game table, a code reading unit 8 that reads a code C representing the number (rank) of the card 1 when the card 1 is manually taken out from the card storage unit 2C by a casino dealer or the like, a win / loss determination unit 10 that determines the win / loss of the card game based on the number (rank) of the card 1 sequentially read by the code reading unit 8, and an output means 11 that outputs the determination result of the win / loss determination unit 10 are provided.

[0015] FIG. 4 shows the card 1 that constitutes the shuffle playing card 1s. On the card 1 used in table games such as baccarat, the numbers are encoded and printed as marks M in UV ink or the like that are normally invisible to the eye. The code C composed of the marks M is provided symmetrically with respect to the upper side and the lower side of the card 1. The code C is preferably printed with a paint that is visualized by receiving ultraviolet light and is printed at a position that does not overlap with the card type notation or index.

[0016] Next, the details of the code reading unit 8 that reads the code C representing the number (rank) of the card 1 from the card 1 when the card 1 is manually taken out from the card storage unit 2C will be described with reference to FIG. 5. FIG. 5 is a plan view of the main part of the card shooter device 2. In the figure, the code reading unit 8 is provided in the card guide unit 7 that guides the cards 1 manually taken out one by one from the opening 13 in front of the card storage unit 2C onto the game table. The card guide unit 7 is an inclined surface, and card guide covers 14 that also serve as sensor covers are attached to both side edges. Each of the two card guide covers 14 is detachably attached with a screw or the like (not shown). When the card guide cover 14 is removed, the sensor group 15 of the code reading unit 8 is exposed. The sensor group 15 consists of four sensors and is composed of two ultraviolet reaction sensors (UV sensors) 20, 21 and object detection sensors 22, 23. Note that an ultraviolet reaction sensor 24 that reads the combined code SC is provided near the two ultraviolet reaction sensors (UV sensors) 20, 21, has the same function as the ultraviolet reaction sensors 20, 21, and outputs an output signal depending on the presence or absence of the combined code SC.

[0017] The object detection sensors 22 and 23 are fiber optic sensors that detect the presence or absence of the card 1 and can detect the movement of the card 1. The object detection sensor 22 is located upstream along the flow direction of the card 1 (arrow F) in the card guide portion 7, and the other object detection sensor 23 is located downstream. As shown in the figure, both object detection sensors 22 and 23 are provided upstream and downstream with the UV sensors 20 and 21 interposed therebetween. The UV sensors 20 and 21 include LEDs (UV LEDs) that emit ultraviolet rays and detectors. On the card 1, a mark M is printed with ultraviolet light-emitting ink that changes color when irradiated with ultraviolet rays. When the card 1 is irradiated with ultraviolet rays (black light), the reflected light of the mark M of the code C on the card 1 is detected by the detector. The UV sensors 20 and 21 are connected to the control unit 12 of the code reading unit 8 via cables. In the code reading unit 8, the combination of the marks M is determined from the output signals of the detectors of the UV sensors 20 and 21, and the number (rank) corresponding to each code C is determined.

[0018] Based on the detection signals of the object detection sensors 22 and 23, the start and end of the reading of the UV sensors 20 and 21 are controlled by the control unit 12 in the code reading unit 8. Further, the control unit 12 determines whether or not the card 1 has passed through the card guide portion 7 normally based on the detection signals of the object detection sensors 22 and 23. As shown in FIG. 4, rectangular marks M representing the rank (number) and suit (such as heart or spade) of the card are arranged in two rows and four columns at the edge of the card 1. When the UV sensors 20 and 21 detect the mark M, they output an on signal. In the code reading unit 8, the relative relationship between the two signals input from the two UV sensors 20 and 21 is determined. Thereby, the code reading unit 8 identifies the code and the number (rank) and type (suit) of the corresponding card 1 based on the relative differences between the two marks M detected by the two UV sensors 20 and 21.

[0019] The relationship between code C and the output of the on-signals of the two UV sensors 20 and 21 is shown in FIG. 6. Based on the comparison result of the relative change in the output of the on-signals of the UV sensors 20 and 21, a predetermined combination of marks M can be identified. As a result, four types can be formed as the combination of the marks M in the upper and lower two rows, and when these are printed in four columns, 256 types of codes can be configured by taking the fourth power of the four types. Each of the 52 cards of the playing cards is assigned to one of the 256 types of codes, and this is stored in memory or a program as a reference table. The code reading unit 8 identifies each code C, and thereby the number (rank) and type (suit) of card 1 are identified from a predetermined reference table (not shown). Also, since the 256 types of codes can be stored in the reference table by associating them with the 52 cards in a free combination, the combination can be made complex, and the combination of the 256 types of code C and the suit and rank of the 52 cards can be changed depending on time and location. It is desirable that code C is printed with a paint that is visualized by receiving ultraviolet light and is printed at a position that does not overlap with the type notation or index of the card.

[0020] Next, the control unit 12 will be described in detail. The control unit 12 is a computer device and includes, for example, a win / loss determination unit 10 that automatically determines the win / loss of a game. These processing functions (within the control unit 12) are realized by incorporating a win / loss determination program into the computer, and this program is executed by the computer's processor. Also, it reads and stores in the read memory 12M a shuffle card ID that can individually identify the shuffle playing cards 1s from the barcode 3 read by the barcode reader 100. The control unit 12 reads the barcode 3 by the barcode reader 100, stores the shuffle card ID that can be individually identified, and identifies and stores the shuffle playing cards 1s as the card set currently used in the game together with the current time in association with the shuffle card ID. The control unit 12 further stores in the memory 12M in association with the current time for each specific occurrence event the following specific occurrence events that occurred during the use of the shuffle playing cards 1s identified by the shuffle card ID on the game table, in association with the shuffle card ID. Also, it stores whether the occurrence of the specific occurrence event occurred at which position of the shuffle playing cards 1s currently in the card shooter device, or at which game number of an individual game (for each individual game, a win / loss determination is made as to whether the player wins or the banker wins, and after the settlement of the bet chips, the next individual game starts).

[0021] The items of specific occurrence events stored in association with the shuffle card ID include at least one of the following. (1) There was a card reading error of the specifically identified shuffle playing card in the card reading unit 8. (2) The game ended due to the operation of the end button 53 to end the use of the shuffle playing cards 1s currently in the card shooter device 2 or due to the appearance of the cut card 1c from the currently existing shuffle playing cards 1s. (3) An attempt was made to draw a card when a card should not have been drawn according to the rules of the card game. (4) The card attempts to move or be inserted in a direction opposite to the drawing direction at the opening 13. (5) An abnormal operation that has been preset to cause the card shooter device 2 to determine an abnormality has occurred. It has a configuration including at least one of the above.

[0022] Note that the reading error in (1) means that in the code reading unit 8 that reads the two marks M of the card 1, the code cannot be identified from a control table or the like as a predetermined code, or the number (rank) and type (suit) of the card 1 corresponding to the code cannot be identified. When ending the use of the shuffled playing cards 1s currently in the card shooter device 2 the end button 53 is pressed. By this operation, the end of the game is registered in the card shooter device 2. Also, when a cut card 1c appears from the shuffled playing cards 1s currently existing in the card shooter device 2, the game ends after the next game or several games in which the cut card 1c appears, and the remaining shuffled playing cards 1s are not used in the game thereafter. Regarding the situation where a card is about to be drawn when it should not be drawn according to the rules of the card game in (3), it will be explained later. The situation where the card is about to be inserted in the reverse direction from the opening 13 in (4) means that the object detection sensors 22, 23 detect an illegal act in which the card is inserted in a direction opposite to the movement of the card 1 in the state (arrow F). It is assumed that the object detection sensors 22, 23 detect the movement of the card 1 in the direction opposite to the arrow F. The abnormal situation stored in advance in the card shooter device 2 as shown in (5) to be determined as abnormal means, for example, when the card 1 abnormally stays on the object detection sensors 22, 23 for a predetermined time, etc., and is input and stored in the memory 12M in advance as a program.

[0023] The 12M memory stores, for each shuffled card ID read from barcode 3, the fact that security items have been generated in association with this shuffled card ID, and stores the time when the security items were generated when storing the security items. For this reason, it is equipped with a clock 12t that knows the current time. It further includes a transmission device 300 that transmits to the outside the fact that security items have been generated together with the shuffled card ID. To the casino management department and the pit via the external transmission device 300, it is notified that security items have been generated in association with each shuffled card ID and the time when the security items were generated. In the casino management department, these transmitted items are stored and registered in the database 400 in association with the shuffled card ID. Furthermore, the fact that security items have been generated is displayed by the lamp 51 and the liquid crystal display unit 52 to inform dealers and the like.

[0024] Next, a modified example equipped with an input means 200 instead of the barcode reader 100 that can identify the shuffled card ID will be described. Instead of using the barcode reader 100 to read barcode 3 and identify the currently used shuffled card ID, a barcode reader is provided in another device (for example, a card 1 disposal device or a discarded card confirmation device) installed on the game table. By this barcode reader, the shuffled card ID to start using is acquired, and by communicating 201 with these devices, the shuffled card ID may be input into the card shooter device 2. In this case, another device equipped with a barcode reader becomes an input device that can identify the shuffled card ID.

[0025] Next, the card access restriction means 30 that restricts the insertion and removal of the card 1 from the card storage section 2C will be described with reference to FIG. 7. The card guide section 7 is provided with card access restriction means 30 that restricts the insertion and removal of the card 1 from the card storage section 2C. In FIG. 7(a), the card access restriction means 30 is provided on the card guide cover 14 of the card guide section 7 that guides the card 1 taken out one by one from the front opening 13 of the card storage section 2C onto the game table. The card access restriction means 30 has a structure in which when the card 1 passes through the slot 33 between the card guide section 7 and the card guide cover 14, the lock member 34 presses the card 1 to prevent the card 1 in the slot 33 from being inserted or removed. The lock member 34 can take two states, a position (restricted position) where it presses the card 1 and a passable position where the card 1 can pass through, and moves as shown by the arrow Mo so as to be able to move between these two states. The drive section 35 is controlled by the control section 12 and moves the lock member 34 between two states, a position where it presses the card 1 and a passable position where the card 1 can pass through. The rules of the baccarat game are pre-programmed and stored in the control section 12.

[0026] Next, a modified example of the card access restriction means 30 will be described with reference to FIG. 7(b). In the modified example, the card access restriction means 40 has a structure in which when the card 1 passes through the slot 33 between the card guide section 7 and the card guide cover -14, the lock member 36 protrudes into the slot 33 to prevent the movement of the card 1. The lock member 36 can take two states, a position (restricted position) where it prevents the movement of the card 1 and a passable position where the card 1 can pass through, and moves as shown by the arrow Mo so as to be able to move between these two states. The drive section 37 is controlled by the control section 12 and moves the lock member 36 between two states, a position where it presses the card 1 and a passable position where the card 1 can pass through.

[0027] The control unit 12 controls the drive units 35 and 37 according to the program to prevent unauthorized insertion and removal of Card 1, thereby enabling the card access restriction means 30(40) to function. The card access restriction means 30(40) is provided with object detection sensors 22 and 23 as sensors for detecting the movement of Card 1, and has a function of detecting the movement of Card 1 by these sensors and restricting the movement of Card 1. The content to be controlled as unauthorized insertion and removal of Card 1 (the programmed content) includes at least the following.

[0028] 1) A function of preventing the insertion of Card 1 inserted or moved in a direction opposite to the direction of arrow F from the outside through the opening 13 toward the card storage section 2c. In this case, when inserting a card 1 for an illegal purpose, the card 1 passes through the slot 33 between the card guide section 7 and the card guide cover 14. Based on the detection signals of the object detection sensors 22 and 23, the movement of Card 1 in the direction opposite to the normal direction (the direction opposite to the arrow F in Fig. 3) is detected, and the drive units 35 and 37 move the locking members 34 and 36 to positions where they press or block Card 1 according to the program of the control unit 12. In this case, the control unit 12 determines that the card is about to be inserted or moved in the reverse direction from the opening in the security item (4).

[0029] 2) The card reading unit (which means the code reading unit 8 that reads the code C representing the number (rank) of the card 1 from the card 1 when the card 1 is drawn out of the card storage unit 5) has a function of preventing the card 1 from being drawn when it should not be drawn out of the card storage unit 2c based on the information of the suit trunk of the card 1 read in the card reading unit. In this case, in advance, the rules of the baccarat game are programmed in the control unit 12 as described above. In the baccarat game, whether the banker and the player should draw two or more cards of the card 1 is uniquely determined by the total of the ranks (numbers) of the two cards already distributed to the banker and the player. Therefore, when the dealer of each table tries to distribute the card 1 when the third card should not be drawn, it is a rule violation, so the movement of the card 1 is restricted. When the card 1 is about to be drawn at a timing or situation when it should not be drawn, based on the detection signal of the card 1 by the object detection sensor 22, the movement of the card 1 is detected, and the drive units 35, 37 move the lock members 34, 36 to the position where they press or block the card 1 according to the program of the control unit 12. As a result, the lock members 34, 36 move to the position where they press or block the card 1, preventing further distribution of the card 1 (the position shown in Fig. 4). In this case, the control unit 12 determines when a card is about to be drawn when it should not be drawn according to the rules of the card game in the security item (3). This corresponds to item (3) of the specific occurrence items stored in association with the shuffling card ID described above. That is, in the above item (3), the fact that a card is about to be drawn when it should not be drawn according to the rules of the card game is registered in the control unit 12.

[0030] When an event corresponding to the above-mentioned specific occurrence event (security item) occurs, the management department or pit of the casino is notified via the external transmission device 300 of the occurrence of the security item in association with the shuffle card ID for each shuffle playing card 1s, and the time when the security item occurred. This information is then connected to and stored in the database 400. Furthermore, the occurrence of the security item is displayed by the lamp 51 and the liquid crystal display unit 52 to inform dealers and the like. In the management department of the casino, these transmitted items are related to the shuffle playing card IDs specified for the card set used in the current game in the database 400, and at least one of the following items is registered in association with the database and used for the overall control and efficiency improvement of the casino's operations.

[0031] For the overall control and efficiency improvement of the casino's operations, the following data is registered in the database and used together in the casino management department. (1) The game table used, (2) The dealer (the person who draws the cards) in charge of the game table used, (3) The start time of use of the specified shuffle playing card, (4) The end time of use of the specified shuffle playing card, (5) The time the specified shuffle playing card existed on the game table, (6) Information regarding the pit or card room that manages the stage before the specified shuffle playing card is transported to the game table where it is used, (7) Information regarding the disposal process until the specified shuffle playing card is discarded after being used on the game table, (8) Information regarding whether the specified shuffle playing card has reached the disposal device, (9) Information regarding the management pit or card room at the stage before the specified shuffle playing card is transported to the game table in advance. (10) Information regarding wins and losses at a game table where the specified shuffle playing card was used, (11) The time from when the game using the specified shuffle playing card ends until it is replaced with the next shuffle playing card and the next game starts, (12) The time from the start to the end of the game using the specified shuffle playing card, (13) Information regarding the purchase or acquisition of the specified shuffle playing card.
