DESCRIPTION OF EMBODIMENTS

[0022] A detailed description of the present invention will be described below. However, the following detailed description and appended drawings do not limit the invention. Instead, the scope of the invention is defined by the appended claims.

[0023] A description will be given regarding a set 1s of shuffled playing cards used in a table game system according to a first embodiment of the present invention. Each of the shuffled playing card sets is used in a game table of a casino is configured of a predetermined number of decks (generally, 6, 8, 9 or 10 decks), shuffled in a random order and arranged in a unique and random arrangement order, and are packed as a package PA to which a uniquely identifiable shuffled card ID (a bar code BC, an RFID tag, or the like) is attached as an ID code at a factory. In this embodiment, the ID code is attached to the package PA in the form of the bar code BC (which may be a two-dimensional code such as QR code (registered trademark)) or the form of the RFID tag or the like to be read by a bar code reader R of a card shoe apparatus S or another RFID tag reading means (not illustrated). The package PA is sealed by a sealing material or a shrink packaging material at the factory.

[0024] Next, a description will be given regarding a procedure of accommodating the shuffled playing card 1s used in the table game system of the present invention in the card shoe apparatus S. As illustrated in FIGS. 9 and 10, at the time of accommodating the shuffled playing card set 1s packed in the package PA in the card shoe apparatus S, a side face of the package PA is removed along a cut line Z provided in the package PA, a part of the shuffled playing card set 1s is set to be exposed, and then, the set 1s is grasped, lifted up, and accommodated into a card accommodation portion 2 of the card shoe apparatus S. Incidentally, a cut card 1c, for stopping in the middle use of the shuffled playing card set is in a subsequent card game, may be inserted at the time of setting a part of the shuffled playing card set 1s to be exposed (see FIGS. 7 and 10). After accommodating the shuffled playing card set is in the card accommodation portion 2, a part of the remaining package PA is removed from the card accommodation portion 2, and only the shuffled playing card set 1s is left in the card accommodation portion 2, thereby completing the accommodation.

[0025] Next, the card shoe apparatus S used in the table game system of the present invention will be described. The card shoe apparatus S includes: a card accommodation portion 2 that accommodates a plurality of the shuffled playing cards 1s; a lid 3 that is provided on a top of the card accommodation portion 2; an opening 6 which is configured to take out shuffled playing cards 1 when a dealer D or the like of a casino manually withdraws the shuffled playing cards one by one from the card accommodation portion 2 toward a game table 4; a card reading unit 110 that reads information representing at least the numeral (rank) of the shuffled playing cards 1; a storage apparatus 20 which stores at least information on a rank of a card read by the card reading unit 110; and a management control unit 19 that is capable of calculating the number of cards per rank based on the information on at least the rank of each card stored in the storage apparatus 20. Incidentally, the card reading unit 110 may have a structure to read a code C of the card 1 using UV sensors 120 and 121 to be described later, a structure to read an index 105 that has been printed on the shuffled playing card 1 with a camera or the like, or a structure of combining the both structures.

[0026] A card pressing portion 32 including a roller 31 is disposed behind the shuffled playing card 1 accommodated in the card accommodation portion 2, and a slope is provided so that the card accommodation portion 2 descends forward. Thus, it is configured such that the shuffled playing card 1 is always pressed to the front from the back by the card pressing portion 32. Thus, the shuffled playing card 1 at the foremost position among the shuffled playing card sets 1s accommodated in the card accommodation portion 2 reaches the vicinity of a front end portion of the card accommodation portion 2, and a part of the foremost shuffled playing card 1 is exposed to the outside through the opening 6.

[0027] Here, the above-described cut card 1c is inserted into a rear half portion (the remnants are about one fourth or one fifth) of the shuffled playing card set 1s at the time of using the shuffled playing card set 1s in a game. Thus, when the shuffled playing cards 1 of the shuffled playing card set 1s accommodated in the card shoe apparatus S are withdrawn and used one by one in the game, the cut card 1c is used to end the game in a state where about 20 to 40 cards are left in the card shoe apparatus S in order to prevent the numeral (rank) of the distributed shuffled playing cards 1 from being counted by a player and the numeral (rank) of the remaining shuffled playing cards 1, which is few, from being predicted. Generally, when the cut card 1c is withdrawn during a game, the use of the shuffled playing card set 1s accommodated in the card shoe apparatus S is ended at the time of ending the corresponding game, the subsequent game after the withdrawal of the cut card 1c, or a game after a predetermined number of times after the withdrawal of the cut card 1c, and the shuffled playing card 1 remaining in the card shoe apparatus S is replaced with a new shuffled playing card set 1s. A code representing the cut card 1c may be attached to the cut card 1c, and the card reading unit 110 may be configured to be able to read the cut card 1c.

[0028] Here, when the shuffled playing card 1 remaining in the card accommodation portion 2 of the card shoe apparatus S is removed and replaced with the new shuffled playing card set 1s, conventionally, the dealer D opens the lid 3 of the card shoe apparatus S and manually takes out the shuffled playing card 1 so that there is a possibility that problems such as extraction and a loss may occur. In the present invention, it is possible to take out the shuffled playing card 1 remaining in the card accommodation portion 2 of the card shoe apparatus S using a card feeding apparatus 11 without using the above-described method. Details will be described below.

[0029] As described above, when the use of the shuffled playing card set 1s accommodated in the card shoe apparatus S is ended at the time when the game after the predetermined number of times played after the withdrawal of the cut card 1c is ended, the card 1 that has not been used in the game remains in the card accommodation portion 2. The card shoe apparatus S in this state will be mounted to the card feeding apparatus 11, and the card 1 remaining without being used in the game will be automatically fed to the outside of the card shoe apparatus S by the card feeding apparatus 11. When the card feeding apparatus 11 automatically feeds the card 1 to the outside of the card shoe apparatus S, the card reading unit 110 reads at least the rank of the card 1 to be fed out, and this information is stored in the storage apparatus 20. The management control unit 19 calculates at least the number of cards 1 fed by the card feeding apparatus 11 for each rank based on the information on at least the rank of each of the cards 1 stored in the storage apparatus 20.

[0030] Next, details of the card feeding apparatus 11 will be described with reference to FIGS. 1 to 4. The card feeding apparatus 11 has a rectangular parallelepiped shape, and includes a cradle 12, which supports the card shoe apparatus S at a bottom face, at a lower part and a front cover 13 which covers a front portion of the card shoe apparatus S by allowing the card shoe apparatus S to be fit therein, at a front part and a card stocker 14 which accommodates the fed card 1. Two rollers 17 (a roller (1) and a roller (2)) are provided on the rear face of the front cover 13, and these two rollers 17 are installed at a position in contact with the card 1 present at the opening 6 of the apparatus S when the card shoe apparatus S is mounted to the card feeding apparatus 11. Further, the roller 17 is connected to a motor 18 configured to move the roller 17, and a card feeding mechanism 26 is configured of the rollers 17 and the motor 18. The motor 18 is connected to a control apparatus 16 inside the card feeding apparatus 11, and an activation means 15 for operating the control apparatus 16 is provided at the rear face of the front cover 13. The roller (1) is brought into contact with the foremost card 1 among the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S, and is configured such that the foremost card 1 among the shuffled playing cards 1 is withdrawn from the card shoe apparatus S by a frictional force along with the rotation of the rollers 17. Further, the shuffled playing card 1 withdrawn from the card shoe apparatus S by the roller (1) is fed into the card stocker 14 by the roller (2) and accumulated therein.

[0031] After the use of the card 1 accommodated in the card accommodation portion 2 is completed, the card shoe apparatus S is placed on an upper face of the cradle 12, and the card shoe apparatus S is mounted such that a front part thereof is fitted to an inner side of the front cover 13. When the card shoe apparatus S is mounted to the card feeding apparatus 11 in this manner, the activation means 15 provided in the rear face of the front cover detects the card shoe apparatus and performs the activation. When the activation means 15 performs the activation, a signal to move the motor 18 is fed to the control apparatus 16, and the motor 18 is operated. When the motor 18 is operated, the rollers 17 are driven to rotate, and the card 1 in contact with the roller among the cards 1 remaining in the card accommodation portion 2 is withdrawn forward.

[0032] Thereafter, the card withdrawn forward by the rollers is further accumulated in the card stocker 14 positioned in front of the opening 6 of the card shoe apparatus S. When the rollers are driven to rotate in this manner, the cards remaining in the card accommodation portion are successively withdrawn forward and accommodated in the card stocker 14. As the above-described motions are repeated, all the cards 1 remaining in the card accommodation portion 2 are accommodated in the card stocker 14. When all the cards 1 remaining in the card accommodation portion 2 are withdrawn from the card accommodation portion 2 and the card 1 in contact with the rollers 17 disappears, the operation of the rollers 17 is stopped. Alternatively, the roller 17 may be provided with an additional stop means (not illustrated) so that the operation of the roller 17 is stopped when the stop means is activated. Incidentally, it is impossible to automatically feed a card using a feeding apparatus at the time of manually feeding the card.

[0033] At least the number of sheets for each rank of the cards 1 which have been manually withdrawn before the use of the card 1 accommodated in the card accommodation portion 2 is ended and at least the number of sheets for each rank of the cards 1 fed by the card feeding apparatus 11 after the use of the card 1 is ended, which are stored in the storage apparatus 20, are added by the management control unit 19, and examination is performed on whether the total number of cards is excessive or insufficient as compared to the number of cards that should be included in a predetermined number of decks. For example, when a game is started in a state where the package PA of the shuffled playing cards 1 configured of eight decks is accommodated in the card accommodation portion 2 of the card shoe apparatus S, there should be eight cards in each rank. Accordingly, the number of cards 1 for each rank is calculated, and whether eight cards are present for the entire rank and there is no excess or insufficiency is examined in a manner such that “whether there are 32 cards of 8 decks×4 types (heart, spade, clover, diamond) for A, whether there are 32 cards of 8 decks×4 types (heart, spade, clover, diamond) for 2, and so on”. This can be changed depending on setting such that whether the excess or insufficiency is examined by comparing information for each suite that needs to be included in a predetermined number of card decks (for example, 104 cards of 13 cards×8 decks for each suite in the case of using the eight decks) and information for each combination of the rank and the suite (for example, 8 cards for each combination of the rank and the suite in the case of using the eight decks).

[0034] An examination result, obtained by examining whether there is no excess or insufficiency when being compared to the information on the number of the shuffled playing cards 1 that should be included in the predetermined number of card decks using the management control unit 19, is displayed in a display means 21. In the display means 21, it is possible to display the information on at least the rank in which the excess or insufficiency exists when it is found to be failed as the examination result. Furthermore, with regard to the information on at least the rank read by the card reading unit 110 and stored in the storage apparatus 20, it is possible to acquire only the information either the information on the number of sheets for each rank of the individual shuffled playing cards 1 manually withdrawn during the game or the information on the number of sheets for each rank of the shuffled playing cards 1 remaining in the card accommodation portion 2 at the time when the use of the card 1 in the card accommodation portion 2 is ended and fed by the card feeding apparatus 11. In addition, it is also possible to display the information on the number of sheets for each rank of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each rank of the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S without being used in the game together depending on the setting. Further, it is also possible to display the information on the number of sheets for each suite of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each suite of the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S without being used in the game, and to display the information on the number of sheets for each combination of the rank and the suite of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each combination of the rank and the suite of the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S without being used in the game.

[0035] In addition, when the cards 1 included in a new package PA are accommodated in the card accommodation portion 2, the ID code attached to the package PA may be read by the bar code reader R of the card shoe apparatus S, and then, results, obtained by sequentially reading at least ranks of the cards 1 withdrawn from the card shoe apparatus S to be used in a game using the card reading unit 110, and information on at least the rank, which is read by the card reading unit 110 when the cards 1 remaining in the card accommodation portion 2 at the time when the use of the card 1 in the card accommodation portion 2 is ended is fed to the outside by the card feeding apparatus 11, may be stored in the storage apparatus 20 in association with information on a shuffled card ID read by the bar code reader R. In that case, it is also possible to display a shuffled card ID of a card as an object to be displayed together at the time of displaying the result of examination of the card and the information on the card in the display means 21.

[0036] In addition, the examination result, obtained by examining whether there is no excess or insufficiency when being compared to the information on the number of the shuffled playing cards 1 that should be included in the predetermined number of card decks using the management control unit 19, is transmitted to a pit, a backyard, or the like by a transmission means 22. The transmission means 22 can perform the transmission together with the information on at least the rank where the excess or insufficiency exists when it is found to be failed as the examination result. Furthermore, with regard to the information on at least the rank read by the card reading unit 110 and stored in the storage apparatus 20, it is also possible to transmit only the information either the information on the number of sheets for each rank of the individual shuffled playing cards 1 manually withdrawn during the game or the information on the number of sheets for each rank of the shuffled playing cards 1 remaining in the card accommodation portion 2 at the time when the use of the card 1 in the card accommodation portion 2 is ended and fed by the card feeding apparatus 11. In addition, it is also possible to transmit the information on the number of sheets for each rank of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each rank of the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S without being used in the game together depending on the setting. Further, it is also possible to transmit the information on the number of sheets for each suite of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each suite of the shuffled playing cards 1 remaining in the accommodation portion of the card shoe apparatus 4 without being used in the game, and to transmit the information on the number of sheets for each combination of the rank and the suite of the individual shuffled playing cards 1 withdrawn during the game and the information on the number of sheets for each combination of the rank and the suite of the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S without being used in the game. In addition, it is also possible to transmit a shuffled card ID of a card as an object to be transmitted together at the time of transmitting the information exemplified as above using the transmission means 22.

[0037] When abnormality is detected as a result of the examination in the management control unit 19, a warning output means 23 can inform the abnormality to the outside. In addition, the warning output means 23 to inform the abnormality may light a display lamp 23 in an arbitrary color or may generate a warning sound. When the examination result is found to be acceptable, the warning output means 23 may be used to light the display lamp in a color different from that in the case of abnormality or to generate a sound using a sound different from that in the case of abnormality depending on setting.

[0038] Incidentally, the management control unit 19 may be included in the card feeding apparatus 11 or included inside the card shoe apparatus S.

[0039] Next, a modified example of the card feeding apparatus 11 will be described. In FIGS. 5 and 6, the card feeding apparatus 11 forms a part of the card shoe apparatus S. The card feeding apparatus 11 is provided in a form of an inverted U-shaped plate 24 and can be mounted on the front face of the card accommodation portion 2 so as to cover the front face of the card accommodation portion 2 of the card shoe apparatus S. The opening 6 is formed to withdraw the card 1 from the card accommodation portion 2 to the game table 4. Four rollers 17 in total are provided at up and down, left and right on a back face of the plate 24. (Upper rollers (1) and lower rollers (2)). These four rollers 17 are positioned to be in contact with the card 1 on the foremost face of the card accommodation portion 2 of the card shoe apparatus S. Each of the rollers 17 is connected to the motor 18 configured to move the roller 17, and the card feeding mechanism 26 is configured of the rollers 17 and the motor 18. The motor 18 is connected to the control apparatus 16, and a switch 25 configured to operate the control apparatus 16 is provided on a front face of the plate 24. The roller 17(1) is brought into contact with the foremost card 1 among the shuffled playing cards 1 remaining in the card accommodation portion 2 of the card shoe apparatus S, and is configured such that the foremost card 1 among the shuffled playing cards 1 is withdrawn from the card shoe apparatus S by a frictional force along with the rotation of the roller 17(1). Further, the shuffled playing card 1 withdrawn from the card shoe apparatus S by the rollers 17(1) is fed into the card stocker 14 by the rollers 17(2) and accumulated therein.

[0040] When the dealer D manually withdraws the card 1 from the card accommodation portion 2 during a card game, the four rollers 17 play a role of making slip of the card 1 favorable. When the switch 25 on the front face of the plate 24 is activated after the use of the card 1 accommodated in the card accommodation portion 2 is ended, the signal to move the motor 18 is fed to the control apparatus 16, and the motor 18 is operated. When the motor 18 is operated, the roller 17 is driven to rotate, and the card 1 in contact with the roller 17 among the cards 1 remaining in the card accommodation portion 2 is withdrawn forward. At this time, when the card shoe apparatus is installed on the rectangular parallelepiped cradle 12 and the card stocker 14 is installed at the lower part of the opening 6 of the card shoe apparatus S in front of the cradle 12, the card 1 fed by the roller 17 can be received and accumulated by the card stocker 14.

[0041] When the roller 17 is driven to rotate in this manner, the card 1 remaining in the card accommodation portion 2 is successively withdrawn forward and accommodated in the card stocker 14. As the above-described motions are repeated, all the cards 1 remaining in the card accommodation portion 2 are accommodated in the card stocker 14. When all the cards 1 remaining in the card accommodation portion 2 are withdrawn from the card accommodation portion 2 and the card 1 in contact with the rollers 17 disappears, the operation of the rollers 17 is stopped. Alternatively, the roller 17 may be provided with the additional stop means (not illustrated) so that the operation of the roller 17 is stopped when the stop means is activated.

[0042] Next, a card forming the shuffled playing card set is according to the embodiment of the present invention will be described with reference to FIG. 8. The rank (numeral) of each card is encoded and printed on each of the cards 1 used in the table game such as baccarat using a UV ink or the like, as a mark M which is normally invisible. The code C configured of the marks M is point-symmetrically provided on an upper side and a lower side of the card 1. It is desirable that the code C be printed using a paint that is visualized by receiving ultraviolet light and be printed at a position not overlapping with indication for a card type indication or the index 105.

[0043] Next, a description will be given regarding details of the card reading unit 110 that reads the code C representing the rank (numeral) of the card 1 from the card 1 when the card 1 is withdrawn from the card accommodation portion 2 with reference to FIG. 11. FIG. 11 is an enlarged perspective view of a main part in a state where the card reading unit 110 at a tip end of the card shoe apparatus S is exposed. In FIG. 11, the card reading unit 110 is provided in a card guide portion 5 that guides the cards 1, withdrawn one by one from the opening 6 in front of the card accommodation portion 2, onto the game table 4. The card guide portion 5 is an inclined surface, and card guide covers 114 also serving as sensor covers are attached to both edge portions. In addition, each of the two card guide covers 114 can be attached and detached using screws (not illustrated). When the card guides 114 are removed, four sensors of the card reading unit 110 are exposed. The four sensors are configured of two ultraviolet reaction sensors (UV sensors) 120 and 121 and object detection sensors 122 and 123.

[0044] The object detection sensors 122 and 123 are optical fiber sensors that detect presence or absence of the card 1 and can detect the motion of the card 1. The object detection sensor 122 is positioned on an upstream side of the card guide portion 5 along a flow direction (arrow X) of the card 1, and the other object detection sensor 123 is positioned on the downstream side. As illustrated in FIG. 11, both the object detection sensors 122 and 123 are provided on the upstream side and the downstream side with the UV sensors 120 and 121 interposed therebetween. Each of the UV sensors 120 and 121 is provided with an LED (ultraviolet LED) emitting ultraviolet rays and a detector. The mark M of the code C is printed on the card 1 using an ultraviolet light emitting ink which develops color when being shun with the ultraviolet rays. The card 1 is irradiated with the ultraviolet rays (black light), and reflected light of the mark M of the code C of the card 1 is detected by the detector. The UV sensors 120 and 121 are connected to the control unit 10 of the card reading unit 110 via cables. The card reading unit 110 determines a combination of the marks M from output signals of the detectors of the UV sensors 120 and 121, and determines the numeral (rank) corresponding to each of the codes C.

[0045] The card reading unit 110 controls start and end of reading of the UV sensors 120 and 121 using the control unit 10 based on detection signals of the object detection sensors 122 and 123. In addition, the control unit 10 also determines whether the card 1 has normally passed the card guide portion 5 based on the detection signals of the object detection sensors 122 and 123. As illustrated in FIG. 8, the quadrangular marks M representing the rank (numeral) and suite (heart, spade, or the like) of the card are arranged in two rows and four rows at an edge of the card 1. When detecting the marks M, the UV sensors 120 and 121 output an ON signal. The card reading unit 110 determines a correlation between two signals input from the two UV sensors 120 and 121. Accordingly, the card reading unit 110 identifies the code based on a relative difference or the like between the two marks M detected by the two UV sensors 120 and 121, and identifies the numeral (rank) and the type (suite) of the corresponding card 1.

[0046] FIG. 12 illustrates a relationship between the code C and output of the ON signals of the two UV sensors 120 and 121. A predetermined combination of the marks M can be identified on the basis of a comparison result of relative changes of output of the ON signals of the UV sensors 120 and 121. As a result, it is possible to form 256 types of codes as a fourth power of four types when four types of the combination of the marks M in upper and lower two rows are printed for four rows. Each of 52 types of cards of playing cards is assigned to any of the 256 types of codes, and results thereof are stored in a memory or a program as a reference table. The card reading unit 110 is configured to identify the numeral (rank) and the type (suite) of the card 1 from the reference table (not illustrated) set in advance by identifying the respective codes C. In addition, the 256 types of codes can be stored using the reference table to be freely combined and associated with the 52 types of cards, and thus, it is possible to make the combinations complicated, and to change the combinations between the 256 types of code and the 52 types of cards depending on time and locations. It is desirable that the code be printed using a paint that is visualized by receiving ultraviolet light and be printed at a position not overlapping with indication for a card type indication or the index 105.

[0047] Although the various embodiments of the present invention have been described as above, it is a matter of course that the above-described embodiments can be modified by those skilled in the art within a scope of the present invention. For example, fraud in games other than baccarat may be detected according to the present invention. At this time, the apparatuses according to the present embodiments may be appropriately modified in response to the necessity of the game to be applied.
