  Hereinafter, embodiments of the table game system of the present invention will be described. FIG. 1 is a perspective view showing an overview of the entire table game system according to the present embodiment. FIG. 2 is a perspective view of a shuffled playing card used in the table game system of the present embodiment. The shuffle playing cards 1s used in the table game system of the present embodiment are provided in a state where the cards 1 constituting a predetermined number of decks (usually 6, 8 or 10 decks) are shuffled so as to be in a random arrangement. Is done. On the game table, the shuffled playing cards 1s are stored in the card shooter device 2 in a state of being bundled by the binding band (B), and after being stored, the band (B) is removed to remove the band (B). The playing card 1s is ready to distribute the cards 1 one by one. During the game, the card 1 is distributed from the card shooter device 2 to the game table by a dealer.

  The cut card 1c is inserted into the shuffle playing card 1s before being set in the card shooter device 2. When the shuffled playing card 1s is used in a game, the cut card 1c is inserted into the latter half of the shuffled playing card 1s (the remaining is about one fourth or one fifth). In the cut card 1c, the rank of each card 1 distributed during the game is counted by a player or the like, and about 20 to 40 cards 1 are placed in the card shooter device 2 in order to prevent the remaining ranks of cards from being predicted. Used to end the game at the game table in the state of being left. FIG. 3 shows a card 1 constituting the shuffle playing card. On the card 1 used for a table game such as a baccarat, numbers are encoded and printed with UV ink or the like which is normally invisible. In FIG. 3, the code 3 constituted by the mark M is provided point-symmetrically on the upper side and the lower side of the card 1.

  In FIG. 4, the card shooter apparatus 2 for carrying out the table game system of the present invention includes a card guide unit 7 for guiding cards 1 drawn one by one from the card storage unit 5 toward the game table 6, and a card storage unit. 5 includes a code reading unit 8 that reads the code 3 representing the number (number, rank) of the card 1 from the card 1 when the card 1 is drawn from the card 5. Furthermore, the card game rules for determining the outcome of the card game (baccarat game in the present embodiment) are stored, and the card game is won or lost based on the number (rank) of cards 1 read by the code reading unit 8. The control part 12 which determines this is provided. The control unit 12 stores the card game rules in advance in a memory 13 to be described later, and determines whether the player and the banker win or lose from the total number (rank) of hands (hands) made up of several cards 1 dealt. . This determination result is displayed by the output means 11 (consisting of a plurality of lamps).

  The control unit 12 has a memory 13 for storing the information of the card 1 read by the card reading unit 8 for a predetermined number of cards, stores the arrangement of the shuffled playing cards 1s, and when there is an abnormality described later, It has a function to detect this abnormality. When an abnormality in the arrangement of the shuffled playing cards 1 s stored in the card storage unit 5 is detected, a card arrangement abnormality alarm is notified to the casino management department or pit via the external output means 100. Further, the card 1 alignment abnormality lamp 101 and the liquid crystal display unit 102 display an abnormality to notify a dealer or the like. Wired or wireless communication means is used as means for outputting an abnormality alarm.

  The output of the abnormality alarm is a two-stage alarm system, and the first stage is a dealer that plays a role of displaying a warning on the liquid crystal display unit 102 which is a side display of the card shooter device 2 when an abnormality is detected and distributing the card. Only allows you to know this. Next, the second stage is output as a final abnormality display after the end of the game where the abnormality has occurred. In this case, the card arrangement abnormality alarm is notified to the management department or pit of the casino via the external output means 100, and the card 1 arrangement abnormality lamp 101 is lit.

Next, the card arrangement abnormality will be described. A typical example of abnormal card arrangement is shown in FIG. FIG. 5A shows an example in which, as a result of the card 1 being drawn out from the card storage unit 5, the card 1 has the same suit (club), and the numbers (number, rank) sequentially increase from one to one. FIG. 5B shows an example in which nine cards 1 of the same rank (3) are continuously arranged as a result of the cards 1 being pulled out from the card storage unit 5. The shuffled playing card 1s is originally shuffled to have a random arrangement by a random number generator or the like, and the above arrangement indicates that the shuffled playing card 1s is not normally shuffled and is determined to be abnormal. Is done. Examples of possible abnormalities including the above abnormalities are summarized below.
(1) Cases (1, 2, 3, 4 to K (FIG. 5A)) in which the rank continues to increase (decrease) one by one in order.
(2) Case in which the same rank continues for a predetermined number (A, A, A, A-) FIG.
(3) The case where the card repeats the same sequence a predetermined number of times (A, Q, 10, A, Q, 10),
(4) Cases where the same suit lasts more than a predetermined number (such as 13 hearts, hearts, and hearts),
(5) A case where a predetermined number of cards are aligned in advance (this is a case where an array of individual cards is produced in the manufacturing process, and this can also be determined as an unshuffled abnormality.
These abnormal patterns are stored in the memory 13 in advance, and when the predetermined number of cards 1 matches the abnormal pattern as compared with the information of the card 1 read by the control unit 12 by the card reading unit 8, This is a mechanism for determining this as abnormal.

  (5) As a case where the arrangement of the pre-registered cards matches a predetermined number as an abnormality of the arrangement of the shuffled playing cards, the state where the card that appeared and the card that appeared 53 times are the same suit and rank There may be a case in which multiple occurrences occur continuously. In this case, when a plurality of decks are shuffled, it is possible to detect an abnormal case where cards are not shuffled for some reason and cards appear in the same pattern in 52 units. As another abnormal case, it is conceivable that a card sequence peculiar to the manufacturing process that occurs in the card manufacturing stage is defined as abnormal and stored in advance.

  An abnormality in the arrangement of shuffled playing cards is a case where a predetermined number of abnormal situations occur continuously, but as a stage before the predetermined number of abnormalities continues, if an abnormality notice is output before the predetermined number of sheets, good. The content indicates a notice different from the final warning, and is output by, for example, characters, colors, or different lamps. Moreover, since it is a notice to the last, the warning notice is canceled when the card that appears does not continue for a predetermined number and returns to a random state.

  Next, details of the code reading unit 8 for reading the code 3 from the card 1 will be described with reference to FIG. FIG. 6 is an enlarged plan view of the main part of the card shooter device 2. In the figure, there is a partially enlarged portion for explanation, so there is an error in relative dimensions. The code reading unit 8 is provided in the card guide unit 7 that guides the cards 1 taken out one by one from the opening 13 in front of the card storage unit 5 onto the game table 6. The card guide part 7 is an inclined surface, and a card guide 14 that also serves as a sensor cover is attached to edges on both sides. Each of the two card guides 14 can be attached and detached with screws or the like (not shown). When the card guide 14 is removed, the sensor group 15 of the code reading unit 8 is exposed. The sensor group 15 includes four sensors, and includes two ultraviolet reaction sensors (UV sensors) 20 and 21 and object detection sensors 22 and 23.

  The object detection sensors 22 and 23 are optical fiber sensors that detect the presence or absence of the card 1. The object detection sensor 22 is located on the upstream side of the card guide unit 7 along the flow direction of the card 1, and the other object detection sensor 23 is located on the downstream side. As shown in the figure, both object detection sensors 22 and 23 are provided on the upstream side and the downstream side with the UV sensors 20 and 21 interposed therebetween. The UV sensors 20 and 21 include LEDs that emit ultraviolet rays (ultraviolet LEDs) and detectors. The card 1 is printed with a code M with ultraviolet light-emitting ink that develops color when exposed to ultraviolet light. The card 1 is irradiated with ultraviolet light (black light), and the reflected light of the mark M of the code 3 of the card 1 is detected. Detected by the instrument. The UV sensors 20 and 21 are connected to the control unit 12 of the code reading unit 8 through a cable. 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 3 is determined.

  In the code reading unit 8, the start and end of reading of the UV sensors 20 and 21 are controlled by the control unit 12 based on the detection signals of the object detection sensors 22 and 23. The control unit 12 also determines whether or not the card 1 has normally passed through the card guide unit 7 based on detection signals from the object detection sensors 22 and 23. As shown in FIG. 3, square marks M representing the rank (number) and soot (heart, spade, etc.) of the card are arranged in two columns and four rows on the edge of the card 1. When detecting the mark M, the UV sensors 20 and 21 output an ON signal. The code reading unit 8 determines the relative relationship between both signals input from the two UV sensors 20 and 21. Accordingly, the code reading unit 8 identifies the code based on the relative difference between the two marks M detected by the two UV sensors 20 and 21, and the number (rank) and type (suit) of the corresponding card 1 are identified. Is identified.

  The relationship between the code 3 and the output of the ON signals of the two UV sensors 20, 21 is shown in FIG. A predetermined combination of the marks M can be specified based on the comparison result of the relative change in the ON signal output of the UV sensors 20 and 21. As a result, when four types of combinations of the upper and lower two rows of marks M are printed, and four of these are printed, 256 types of codes can be configured by four types of fourth power. 52 cards of the playing card are assigned to any of the 256 codes, stored in a memory or program as a comparison table, and the code reading unit 8 specifies each code 3 in advance. The number (rank) and type (suit) of cards 1 are specified from a comparison table (not shown). In addition, since 256 codes can be stored in a comparison table in association with 52 cards in any combination, the combination can be complicated, and combinations of 256 codes and 52 cards depending on time and place. Can be changed. The code 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 the index 102.

  Next, details of the configuration of the control unit 12 will be described. The control unit 12 or the like is a computer device, and for example, the processing function (in the control unit 12) for automatically determining whether or not a game is won or lost is realized by incorporating a win / loss determination program into the computer. Is executed by the processor of the computer. The code reading unit 8 uses the UV sensors 20 and 21 to acquire the number of cards sequentially taken out to the game table 6, and the acquired number of cards is sequentially stored in the memory 13. At this time, information on the order in which the cards 1 are distributed and distributed to the players is also stored. The number of cards and how the suits appeared in sequence are stored. The shuffled playing card 1s is originally shuffled so as to have a random arrangement by a random number generator or the like, but if an abnormal pattern as described above appears, the shuffled playing card 1s may not be shuffled normally. Indicates that there is. The arrangement of cards to be determined as abnormal patterns is stored or programmed in advance in the memory 13, and is compared with the arrangement information actually distributed on the card 1 read by the card reading section 8 by the control section 12. When one predetermined number of sheets appear in an abnormal pattern, this is determined to be abnormal.

  As an application example of the above-described embodiment, the present invention can be applied to a shuffled playing card reading device on a game table. In this case, based on the card reading unit that reads the card information attached to the card put on the game table from the card and the card information read by the card reading unit, the arrangement of the shuffled playing cards is inspected. The present invention comprises a control unit that The reader can be arranged above the game table in the casino venue and can be configured to read cards.
