[0010] An embodiment of the table game system of the present invention will be described below. 2 is a perspective view showing an overview of the entire table game system of this embodiment. FIG. 1 is a perspective view of shuffled playing cards used in the table game system. The shuffled playing cards used in the table game system of the form A number of decks (usually 6, 8 or 10 decks) are made up of cards arranged randomly. On the game table, the cards are shuffled. The playing cards 1s are bundled together with a bundling band (B) and stored in the card shooter device 2. After it is stored, the belt (B) is untied and removed, and the shuffle playing card is During the game, the card shooter device 2 Card 1 is dealt to the gaming table by the dealer.

[0011] The shuffled playing cards 1s are given a card slot before being set in the card shooter device 2. The cut card 1c is inserted into the shuffled playing card 1s. When using the game, shuffle the second half of the playing cards (the remaining quarter The cut card 1c is inserted into each card dealt during the game. The rank of the first card is counted by the player, and the rank of the remaining cards is predicted. To prevent this, leave about 20 to 40 cards 1 in the card shooter device 2. This is used to end the game on the game table. Figure 3 shows the same shuffle playing The cards 1 that make up the deck are shown. The cards 1 used in table games such as baccarat include The numbers are coded and printed with UV ink, which is normally invisible. A code 3 consisting of marks M is provided point-symmetrically on the top and bottom sides of the card 1.

[0012] In FIG. 4, the card shooter device 2 of the table game system of the present invention is A card guider guides the cards 1 drawn one by one from the card holder 5 onto the game table 6. When the card 1 is drawn out from the card holder 5, the numbers (numbers, numbers, The code reader 8 reads the code 3 representing the card number from the card 1. Rules of a card game for determining the outcome of a game (baccarat game in this embodiment) and based on the number (rank) of cards 1 read by the code reading unit 8, The control unit 12 determines the outcome of the card game. are stored in advance in the memory 13 described later, and the hand consisting of several cards 1 dealt is The total number of hands (ranks) determines the outcome between the player and the banker. It is displayed by a row 11 (consisting of multiple lamps).

[0013] The control unit 12 records the information of the cards 1 read by the card reading unit 8 for a predetermined number of cards. The memory 13 stores the order of the shuffled playing cards 1s. If there is an abnormality in the card, which will be described later, the card has a function to detect this abnormality. If an abnormality in the arrangement of the shuffled playing cards 1s is detected, the external output means 100 An alarm is sent to the casino management department and the pit to notify them of any abnormalities in the card arrangement. The abnormality lamp 101 and the liquid crystal display 102 indicate the abnormality and notify the dealer or the like. The means for outputting the abnormality alarm is a wired or wireless communication means.

[0014] The abnormality alarm is output in a two-stage alarm system. The first stage is when an abnormality is detected. A warning is displayed on the liquid crystal display unit 102, which is a side display of the card shooter device 2, and Only the dealer who distributes the code can know this. The stage number is output as the final abnormality display after the end of the game in which the abnormality occurred. An alarm of abnormal card arrangement is sent to the management department of the casino or the pit through the external output means 100. Furthermore, the card 1 alignment abnormality lamp 101 lights up.

[0015] Next, we will explain card alignment abnormalities. A typical example of card alignment abnormalities is shown in Figure 5. (a) shows that card 1 is drawn from the card storage section 5, and as a result, card 1 is of the same suit (club). ) shows an example where the numbers (number, rank) start from ace and increase by one. Figure 5(b) shows When card 1 is drawn from card storage section 5, nine consecutive cards of the same rank (3) are drawn. Here is an example of shuffled playing cards. The cards are shuffled to have a random order, and the above order is This indicates that the laying cards have not been shuffled properly, and is judged to be an abnormality. Examples of abnormalities, including those mentioned above, are summarized below. (1) The rank increases (decreases) by one in sequence for a predetermined number of times (1, 2, 3 ,4~K (Fig. 5(a)), (2) Case where the same rank continues for a certain number of times (A, A, A, A~) Figure 5(b). (3) The case where the same sequence of cards is repeated a certain number of times (A, Q, 10, A, Q, 1 0~), (4) When the same suit appears in a sequence of more than a certain number of cards (e.g., 13 consecutive hearts, hearts, hearts, etc.) degree), (5) Cases where the sequence of pre-registered cards matches a predetermined number of cards (individual card manufacturing processes) This is a case where an arrangement like this occurs, and it can also be determined that this is an abnormality where the cards have not been shuffled. These abnormality patterns are stored in advance in the memory 13, and the control unit 12 Compared with the information of the card 1 read by the unit 8, a predetermined number of cards 1 have an abnormal pattern. If the values ​​match, it is determined to be an abnormality.

[0016] (5) Abnormality in the arrangement of shuffled playing cards. In the case where the specified number of cards match, the card that appeared and the card that appeared 53 cards ago There may be cases where multiple cards in a row have the same suit and rank. When shuffling multiple decks, if for some reason they are not shuffled and are separated into 52-card units, This allows for the detection of abnormal cases where codes appear in the same pattern sequence. Another abnormal case is a card misalignment that occurs during the manufacturing process. It is conceivable to define each of these as abnormal and store the information in advance.

[0017] An abnormality in the arrangement of shuffled playing cards occurs when a certain number of abnormal cards occur consecutively. In this case, the abnormality is predicted a few sheets before the specified number of sheets continues. It is better to output a warning that is different from the final warning, e.g., a text The output will be different colors or different lamps. If the predetermined number of cards do not appear in succession and the state returns to random, the warning will be canceled.

[0018] Next, the details of the code reading unit 8 that reads the code 3 from the card 1 will be explained with reference to FIG. FIG. 6 is an enlarged plan view of the main part of the card shooter device 2. Therefore, there are some enlarged parts, so there is a margin of error in the relative dimensions. The cards 1 are taken out one by one from the opening 13 at the front of the card storage section 5, and are then inserted into the game table. The card guide 7 is provided on the card guide portion 7, which guides the card 6 onto the card guide portion 7. The card guide portion 7 is an inclined surface. Card guides 14, which also serve as sensor covers, are attached to the edges on both sides. In addition, each of the two card guides 14 is detachably attached 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 is made up of four sensors, two ultraviolet ray reaction sensors (UV sensors) 20 and 21. and object detection sensors 22 and 23.

[0019] The object detection sensors 22 and 23 are optical fiber type 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 section 7 along the direction in which the card 1 flows. The other object detection sensor 23 is located downstream. The object detection sensors 22 and 23 are provided on the upstream and downstream sides of the UV sensors 20 and 21. The UV sensors 20 and 21 are equipped with an LED that emits ultraviolet light (ultraviolet LED) and a detector. The card 1 is coated with UV-emitting ink that changes color when exposed to UV light. The word "M" is printed on the card, and when ultraviolet light (black light) is irradiated onto the card, The reflected light from the mark M on the cord 3 is detected by the detector. The code reader 8 is connected to the control unit 12 of the code reader 8 via a UV sensor. The combination of marks M is determined from the output signals of detectors 20 and 21 and corresponds to each code 3. The number (rank) is determined.

[0020] The code reader 8 reads the UV sensor 2 based on the detection signals from the object detection sensors 22 and 23. The start and end of reading 0 and 21 are controlled by the control unit 12. Whether the card 1 has passed through the card guide section 7 properly is also determined by the object detection sensors 22 and 23. As shown in Figure 3, the rank (number) and suit (hand) of the card are used to make the decision. The square marks M representing cards such as trophies and spades are arranged in two columns and four rows on the edge of card 1. When the UV sensors 20 and 21 detect the mark M, they output an ON signal. The measuring unit 8 determines the relative relationship between the two signals input from the two UV sensors 20 and 21. This allows the relative difference between the two marks M detected by the two UV sensors 20 and 21 to be detected. The code reader 8 identifies the code and determines the number (rank) and type (score) of the corresponding card 1. Identify the route.

[0021] The relationship between Code 3 and the ON signal output of the two UV sensors 20 and 21 is shown in Figure 7. Based on the comparison result of the relative changes in the ON signal outputs of the sensors 20 and 21, a predetermined value of the mark M is determined. As a result, there are four combinations of the upper and lower two rows of M marks. If you print four rows of this, you can create 256 different codes (four types to the fourth power). The 52 types of cards are assigned to one of 256 codes, and this is used as a comparison table. The code reading unit 8 can identify each code 3. Then, from a predetermined comparison table (not shown), the number (rank) and type (suit) of card 1 are determined. The 256 codes can be freely combined into 52 cards. Since it is possible to associate and store the combinations in a comparison table, the combinations can be made complex. You can change the combination of 256 codes and 52 cards depending on the time and place. The code is printed with paint that becomes visible under ultraviolet light, and the card type is displayed. It is desirable that the mark be printed at a position that does not overlap with the mark or the index 102.

[0022] Next, the configuration of the control unit 12 will be described in more detail. For example, the processing function (in the control unit 12) for automatically determining the outcome of a game is This is realized by incorporating a program for determining the winner into the computer. The code reading unit 8 reads the code from the UV sensor. Use 20 and 21 to get the number of cards that will be taken out sequentially on game table 6, and The number of cards that have been played is stored in the memory 13 in order. The order in which the cards were dealt and the order in which they were dealt to the players are also recorded. The order in which the cards were played is recorded. The cards are shuffled in advance to have a random order, but as mentioned above, When an abnormal pattern appears, the shuffle playing cards are not shuffled properly. The sequence of cards that should be judged as an abnormal pattern is the sequence of cards in memory 1. 3, and the control unit 12 reads it using the card reading unit 8. Compared with the arrangement information of the taken card 1 that was actually distributed, the predetermined number of cards 1 are abnormal. If a pattern appears, it is determined to be an abnormality.

[0023] As an application example of the above embodiment, a shuffle playing card is used on a game table. In this case, the card reader on the gaming table a card reading unit for reading information from a card attached to the card; The arrangement of the shuffled playing cards is detected based on the information of the cards read by the The invention is composed of a control unit that reads the game data and a reader that reads the game data. It can be configured to read cards.
