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

  In the shuffle playing card 1s, the cut card 1c is inserted before being set in the card shooter device 2. When the shuffle playing card 1s is used for the game, the cut card 1c is inserted into the second half of the shuffle playing card 1s (the rest is about 1⁄4 or 1⁄5). The cut card 1c has about 20 to 40 cards 1 on the card shooter device 2 in order to prevent the rank of each card 1 distributed during the game from being counted by the player etc. and the rank of the few cards remaining being predicted. It is used to end the game on the game table in the left state. FIG. 3 shows a card 1 constituting the same shuffle playing card. A card 1 used for a table game such as Baccarat is printed with UV ink or the like in which numbers are coded and which are usually invisible. In FIG. 3, the cords 3 configured by the marks M are provided point-symmetrically on the upper side and the lower side of the card 1.

  In FIG. 4, the card shooter device 2 of the embodiment of the table game system according to the present invention has a card guide portion 7 for guiding the card 1 drawn one by one from the card storage portion 5 onto the game table 6; A card reader 8 has a code reader 8 for reading from the card 1 a code 3 representing the number (number, rank) of the card 1 when the card 1 is withdrawn from the card 5. Furthermore, while storing the rule of the card game for determining the outcome of the card game (the baccarat game in the present embodiment), the outcome of the card game based on the number (rank) of the cards 1 read by the code reading unit 8 Control unit 12 that determines the The control unit 12 prestores the card game rule in the memory 13 to be described later, and determines the outcome between the player and the banker based on the total number of hands (ranks) consisting of several cards 1 dealt. . The determination result is displayed by the output means 11 (composed of a plurality of lamps).

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

  The abnormal alarm output is a two-stage alarm system, and the first stage is a dealer whose role is to display an alarm on the liquid crystal display unit 102 which is the side display of the card shooter device 2 at the time of abnormality detection and distribute the card. Is only able to know this. Next, in the second stage, after the end of the game where an abnormality has occurred, it is output as a final abnormality indication. In this case, an alarm notification of the arrangement of cards is notified to the management department or pit of the casino via the external output means 100, and the arrangement abnormality lamp 101 of the card 1 is turned on.

Next, the card arrangement abnormality will be described. A typical example of a card alignment error is shown in FIG. FIG. 5A shows an example in which as the card 1 is pulled out from the card storage unit 5, the card 1 has the same suit (club) and the numbers (numbers and ranks) start from the ace and sequentially increase by one. FIG. 5B shows an example in which nine cards 1 having the same rank (3) are continuously arranged as a result of the card 1 being pulled out from the card storage unit 5. The shuffle playing card 1s is originally shuffled by a random number generator or the like so as to have a random sequence, and the above sequence indicates that the shuffle playing card 1s is not properly shuffled, and is determined to be abnormal. Be done. Examples that are considered abnormal, including the above-mentioned abnormalities, are summarized below.
(1) A case where the number of ranks sequentially increase (drop) one by one continues a predetermined number of sheets (1, 2, 3, 4 to K (FIG. 5 (a)),
(2) Case where the same rank continues a predetermined number of sheets (A, A, A, A-) FIG. 5 (b),
(3) A case where the card repeats the same sequence a predetermined number of times (A, Q, 10, A, Q, 10),
(4) Case where same suit continues more than predetermined number (Heart, heart, 13 hearts, etc.),
(5) A case in which a predetermined number of registered cards coincide with each other (a case in which the arrangement of individual cards in the manufacturing process appears, and this can also be determined as an abnormality that has not been shuffled.
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, It is a mechanism to judge this as abnormality.

  (5) In the case where the pre-registered card sequence matches the predetermined number of cards as an abnormality in the shuffle playing card sequence, the appeared card and the card appearing 53 cards earlier are in the same suit and rank There may be a case in which a plurality of pieces occur successively. This is to enable detection of an abnormal case where a card appears in the same pattern sequence in units of 52 cards without being shuffled for some reason when shuffling a plurality of decks. As another abnormal case, it is conceivable to define an array of cards specific to a manufacturing process generated at the manufacturing stage of the card as an abnormality and store it in advance.

  An abnormality in the order of shuffle playing cards is a case where a predetermined number of abnormal states occur continuously, but if an abnormality notice is output several minutes before the predetermined number of sheets as a step before the abnormality continues for a predetermined number of sheets. good. It is the contents which show the notice different from the final warning, for example, it outputs with a letter, or a color, or each separate lamp. Further, since it is a notice only, if the appearing card returns to a random state without continuing for a predetermined number of sheets, the warning notice is canceled.

  Next, the 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. There is an error in the relative dimensions as there are partially enlarged portions in the figures for the purpose of illustration. The code reading unit 8 is provided on a card guide unit 7 for guiding the card 1 taken out one by one from the front opening 13 of the card storage unit 5 onto the game table 6. The card guide portion 7 is an inclined surface, and a card guide 14 also serving as a sensor cover is attached to the edge portions on both sides. Further, each of the two card guides 14 is attachable and detachable with a screw 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 response 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 upstream of the card guide 7 along the flow direction of the card 1, and the other object detection sensor 23 is located downstream. As shown in the figure, the two 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 an LED (ultraviolet LED) that emits ultraviolet light and a detector. The code M is printed on the card 1 with an ultraviolet light emitting ink which is colored when exposed to ultraviolet light, the ultraviolet light (black light) is irradiated to the card 1, and the reflected light of the mark M of the code 3 of the card 1 is detected. Detected by The UV sensors 20 and 21 are connected to the control unit 12 of the code reading unit 8 via a cable. The code reading unit 8 determines the combination of the marks M from the output signals of the detectors of the UV sensors 20 and 21 and determines the number (rank) corresponding to each code 3.

  In the code reading unit 8, the control unit 12 controls the start and end of reading of the UV sensors 20 and 21 based on 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 the card guide unit 7 based on the detection signals of the object detection sensors 22 and 23. As shown in FIG. 3, square marks M representing the ranks (numbers) and suits (hearts, spades, etc.) of the cards are arranged in two rows and four rows at the edge of the card 1. When the UV sensors 20 and 21 detect the mark M, they output an ON signal. The code reading unit 8 determines the relative relationship between the two signals input from the two UV sensors 20 and 21. Thereby, the code reading unit 8 identifies the code by the relative difference between the two marks M detected by the two UV sensors 20 and 21, and the number (rank) and type (soot) of the corresponding cards 1 Identify

  The relationship between the code 3 and the output of the ON signals of the two UV sensors 20 and 21 is shown in FIG. The predetermined combination of the marks M can be identified based on the comparison result of the relative change of the output of the UV sensors 20 and 21. As a result, if four types of combinations of marks M in the upper and lower two rows are printed in four rows, 256 types of codes can be configured with four types of fourth powers. Each of 52 types of playing cards is assigned to any of 256 types of codes, which are stored as a comparison table in a memory or program, and the code reading unit 8 is predetermined by specifying each code 3 The configuration is such that the number (rank) and the type (soot) of the cards 1 are specified from the control table (not shown). In addition, 256 types of codes can be associated with 52 types of cards in free combinations and can be stored using a comparison table, so combinations can be complicated, and 256 types of codes and 52 types of cards can be used depending on time and place. You can change the combination. The code is preferably printed with a paint that is visualized by receiving ultraviolet light, and is printed at a position not overlapping the card type indication or the index 102.

  Next, the configuration of the control unit 12 will be described in more detail. The control unit 12 or the like is a computer device, and for example, a processing function (in the control unit 12) for automatically determining the outcome of a game is realized by incorporating a program for outcome determination into a computer. Run on a computer processor. 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 in what order each card 1 is distributed and distributed to the player is also stored. The number of cards and how the suite appeared sequentially is stored. The shuffle playing card 1s is originally shuffled in advance so as to have a random sequence by a random number generator or the like, but if an abnormal pattern as described above appears, the shuffle playing card 1s may not be shuffled normally. Indicates that there is A sequence of cards to be determined as an abnormal pattern is stored or programmed in advance in the memory 13 and compared with the actually distributed sequence information of the card 1 read by the card reading unit 8 by the control unit 12 When a predetermined number of 1 appear in an abnormal pattern, this is determined to be abnormal.

  As an application example of the above embodiment, it is possible to apply to a reader of shuffle playing card on the game table. In this case, the array of shuffle playing cards is inspected based on the card reader reading the card information attached to the card placed on the game table from the card, and the card information read by the card reader. The invention comprises the control unit that A reader may be placed above the gaming table at the casino venue and configured to read the card.
