Description

Technical Field

[0001] The present invention relates to shuffled playing cards and a method for manufacturing playing cards.

Background Art

[0002] In various playing card games such as poker, baccarat, bridge, or blackjack, a dealer sets one deck or multiple decks of playing cards in a card shoe 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, these cards need to be dealt randomly. Therefore, before setting the cards in the card shoe, the game organizer must shuffle the playing cards thoroughly randomly. However, when the game organizer shuffles the cards prior to the game, it may take a long time to shuffle, which has been a factor hindering the efficient operation of the game. In addition, when the game organizer shuffles the cards, there is a problem that there is room for illegal acts such as card insertion and replacement.

[0003]

[0004] To solve such problems, International Publication No. 2009 / 069708 proposes shuffled playing cards in which playing cards constituting a predetermined number of decks are individually packaged in a shuffled state. The packaging of this shuffled playing card is provided with a shuffled playing card ID for accessing on a database the information capable of identifying the shuffling machine or group of shuffling machines that shuffled the shuffled playing card as an ID code. ​

Summary of the Invention

[0005] However, even if an ID code is given to the packaging of shuffled playing cards, when a set of cards with a known order has its contents replaced, there is no means to confirm whether those cards are genuine, and even if fraud is committed in a game using that set, it cannot be discovered.

FIG. 2(a) is a diagram showing the front surface of a card other than the cards that constitute a deck set among playing cards according to one embodiment, and FIG. 2(b) is a diagram showing the back surface thereof. As shown in FIG. 1, one set of playing cards according to the present embodiment includes, as cards that constitute a deck set, four suits 21a (that is, spades, clubs, diamonds, hearts ) and thirteen ranks 21b (that is, A (ace), 2, 3, 4, 5, 6, 7, 8, 9

[0057] , 10, J (jack), Q (queen), K (king)), and has 4 ×13 = 52 cards 21.

[0058]

[0059] In addition, as shown in FIG. 2, one set of playing cards according to the present embodiment further includes a "joker" card 22 as a card other than the cards that constitute a deck set. The "joker" card 22 included in one set of playing cards may be one or two. The "joker" card 22 is a card that is removed and discarded before the shuffling step when creating the shuffled playing cards described later.

[0059] One set of playing cards 21 and 22 according to this embodiment is formed by individually cutting from a single card stock 20 (see Fig. 4).

[0060] As shown in Figs. 1 and 2, on each surface of one set of playing cards 21 and 22, common sheet IDs 31 and 32 are printed, and on the back surface, a common back pattern 29 is printed. The sheet IDs 31 and 32 may be character codes consisting of a plurality of numbers, alphabets, and symbols, or may be barcodes or two-dimensional codes in which the character codes are encoded.

[0061] As shown in Fig. 1, the sheet ID 31 printed on the card 21 constituting the deck may be printed with ink that is invisible to the human eye (for example, transparent UV ink), or may be printed with ink that is visible to the human eye (for example, black ink). When the sheet ID 31 is printed with ink that is invisible to the human eye (for example, transparent UV ink), it looks the same as a conventional card, and the user of the card can use the card without discomfort. On the other hand, when the sheet ID 31 is printed with ink that is visible to the human eye (for example, black ink), although it may make the user of the card feel uncomfortable, since the sheet ID 31 is just an ID code, there is no particular problem in the game. ).

[0062] Also, as shown in Fig. 2, the sheet ID 32 printed on the card 22 other than the cards constituting the deck may be printed with ink that is invisible to the human eye (for example, transparent UV ink), or may be printed with ink that is visible to the human eye (for example, black ink). ​​​​​​​​​​ Yes. When printed with ink visible to the human eye (e.g., black ink), the manufacturer can easily confirm the sheet ID 32 during the manufacturing process when inspecting the quality of the printed cardstock. As shown in FIG. 8, the sheet IDs 31 and 32 printed on each playing card 21 and 22 are associated in the database with one or both of the record of the printing date of the sheet ID on the original cardstock 20 and the record of the cutting date for each individual playing card 21 and 22, and are stored.

[0063] As shown in FIG. 8, the sheet IDs 31 and 32 printed on each playing card 21 and 22 are associated in the database with one or both of the record of the printing date of the sheet ID on the original cardstock 20 and the record of the cutting date for each individual playing card 21 and 22, and are stored.

[0064] FIG. 6 is a diagram showing a shuffle playing card according to the present embodiment before the packaging is sealed with a seal. FIG. 7 is a diagram showing a shuffle playing card according to the present embodiment with a shuffle playing card ID assigned to the seal that seals the packaging.

[0065] The shuffle playing card 12 according to the present embodiment is a sufficient shuffle of a plurality of decks (e.g., 4 decks or 8 decks) of the above-described playing card 21 by a shuffling machine as one set. A different shuffle playing card ID 13a is assigned as an ID code to each set of shuffle playing cards 12. In the illustrated example, the shuffle playing card 12 is stored in a box-shaped package 11, and its lid is sealed with a seal 13. The shuffle playing card ID 13a is encoded as a bar code and printed on the seal 13 that seals the package 11.

[0066] ​​​​​​​​​​​​ As shown in FIG. 8, the playing card 21 that constitutes the shuffle playing card 12 The sheet ID 31 of and the shuffle playing card ID 13a are mutually stored in a database and are associated and stored.

[0067] Next, a method for manufacturing the playing card 21 and the shuffle playing card 1 2 according to the present embodiment will be described. FIG. 3 is a flowchart showing a method for manufacturing the playing card 21 and the shuffle playing card 12 according to the present embodiment.

[0068] In the manufacturing process of the playing card 21 and the shuffle playing card 12 according to the present embodiment, it is preferable that consistent process management is performed from order reception to shipment by a process management system. In the present embodiment, a manufacturing method using such a process management system will be described.

[0069] As shown in FIGS. 3 and 4, first, as a printing process, a suit and a rank are printed on the surface of the card stock 20 by a printing machine, and a back pattern is printed on the back surface (step S40). In the example shown in FIG., 52 cards 21 consisting of combinations of 4 suits and 13 ranks, 1 "Joker" card 22, and 3 other cards 23, a total of 56 cards are printed in an 8-row × 7-column matrix arrangement.

[0070] As a modification, as shown in FIG. 5, 52 cards 21 consisting of combinations of 4 suits and 13 ranks, a total of 105 cards consisting of two decks of such cards and 1 other card 23 may be printed in a 7-row × 15-column matrix arrangement.

[0071] ​​​​​​​​​​ Next, in the sheet ID assignment process, the process control system assigns one card base paper or A different sheet ID is generated for each of the cards, and the sheet ID is printed on the surface of the card base paper 20 by a printing machine. The process IDs 31 and 32 are printed (step S41). The sheet IDs 31 and 32 and the printing dates of the sheet IDs 31 and 32 on the card base paper 20 are stored in the data. The data are stored in a mutually associated manner in the base (see FIG. 8). D31 and 32 are one or more of the following: factory name, production line, customer name (casino name) may be stored in a database in association with

[0072] In this embodiment, the cards 21 constituting the deck are marked with ink that is invisible to the human eye ( For example, sheet ID 31 is printed in transparent UV ink. The cards 21 that make up the card set will look the same as conventional cards, and users of the cards will not feel uncomfortable. You can use the cards without any trouble. The sheet ID 31 is a part of the deck. The card may be printed only on a specific card (e.g., the Ace of Spades) among the 21 cards. Or it may be printed on every card.

[0073] On the other hand, cards 22 and 23 other than the cards that make up the deck have visible ink. The sheet ID 32 is printed in black ink (for example, black ink). The sheet ID can be easily identified when inspecting the quality of the printed card stock. It is Noh.

[0074] In this embodiment, after the printing step (step S40), a sheet ID assignment step ( Step S41) is performed, but not limited thereto. After the sheet ID assignment step (step S4 1), the printing step (step S40) may be performed.

[0075] Next, the card stock 20 that has undergone the printing step (step S40) and the sheet ID assignment step (step S41) is cut into individual cards 21, 22, 23 by a cutting machine ( step S42). From the cut cards, cards 22, 23 other than the cards that make up the deck are removed, and a deck's worth (two decks' worth from the card stock 20 shown in FIG. 5) of playing cards 21 are created.

[0076] Before or during shuffling by a shuffling machine described later, the sheet ID 31 is read from the playing cards 21 that make up the deck by the process management system, and is stored in a database in association with the shuffling machine (or group of shuffling machines) and the date and time of shuffling (see FIG. 8).

[0077] Next, as the shuffling step, a plurality of decks' worth (for example, four decks' worth or eight decks' worth) of playing cards 21 are shuffled by a shuffling machine, and a set of shuffled playing cards 12 is created (step S43). As the shuffling machine, for example, the shuffling machine described in International Publication No. 2009 / 069708 can be used.

[0078] Next, the set of shuffled playing cards 12 that has undergone the shuffling step (step S43) is packaged by a packaging machine (step S44). In the present embodiment, as shown in FIG. 6, the set of shuffled playing cards 12 is stored in a box-shaped package 11. The package 11 ​ The material is not particularly limited and may be paper or a resin film. As shown in FIG. 7, the lid of the package 11 is sealed by a seal 13.

[0079] Next, the process management system generates a different shuffle playing card ID for each set of shuffle playing cards, and assigns the shuffle playing card ID 13a as an ID code to the set of shuffle playing cards 12 (step S45). In the illustrated example, the shuffle playing card ID 13a is encoded as a barcode and printed on the seal 13 that seals the lid of the package 11 by a printing machine.

[0080] In the illustrated example, in addition to the shuffle playing card ID 13a, a specification sheet 13b is printed on the seal 13. The specification sheet 13b describes arbitrary information such as, for example, the manufacturing number, product number, product name, color, and manufacturing date of this shuffle playing card.

[0081] Also, the sheet ID 31 read from the playing cards 21 that make up the deck before the shuffle process (step S43) by the process management system is stored in association with the shuffle playing card ID 13a of the set of shuffle playing cards 12 to which the deck belongs in a database (see FIG. 8). In the illustrated example, one set of shuffle playing cards 12 is composed of playing cards 21 for four decks, and four sheet IDs 31 are stored in association with each shuffle playing card ID 13a in the database.

[0082] According to the present embodiment as described above, different sheet​​​​​​​​​​​​ The card stock 20 printed with sheet IDs 31 and 32 is cut into one deck or multiple decks to create the playing cards 21 of the deck. Thus, it is possible to trace back the distribution history of the playing cards 21 on the database to find out when the cards were printed and when they were inspected. This makes it possible to check, even if the contents of the packaged shuffled playing cards 12 have been replaced with a set of cards whose order is known by a malicious wrongdoer, whether the cards are genuine products that have been correctly manufactured and distributed, by reading the sheet ID 31 from the cards inside and checking the history on the database on a sheet-by-sheet basis. Also, since different sheet IDs 31 and 32 are printed on each one or more card stocks it becomes possible to manage the ID of the card stock 20 in the factory. For example, even if the card stock 20 is discarded halfway it is possible to manage in the database at which stage it was discarded. This makes it possible to grasp the yield at each process in the manufacturing stage. Also

[0083] it becomes possible to find out whether the cards of the card stock judged as defective and discarded at each process have not been accidentally mixed into the products (that is it becomes possible to find out whether only the cards of the good-quality card stock are being used in the products). Furthermore, even if a malicious wrongdoer illegally obtains the discarded card stock 20 cuts it himself to create counterfeit cards, and brings the created counterfeit cards into the game for use it is possible to identify the counterfeit cards by reading the sheet ID 31 from the cards and checking the history on the database It can be easily detected and the security of the game can be enhanced.

[0084] In the above-described embodiment, in the sheet ID assigning step, as shown in FIGS. 6 and 7, sheet IDs 31 and 32 are printed on the portions of the cardstock 20 where the cards 21 to 23 are printed. However, the present invention is not limited to this, and the sheet ID may be printed on the portion of the cardstock 20 where the cards are not printed. In this case, it is possible to obtain the sheet ID from the remaining portion (so-called waste) after removing the cards 21 to 23 from the cardstock 20.

[0085] The above-described embodiment is described for the purpose of enabling a person having ordinary knowledge in the technical field to which the present invention pertains to practice the present invention. Various modifications of the above embodiment are naturally possible for those skilled in the art, and the technical idea of the present invention can also be applied to other embodiments. Therefore, the present invention should not be limited to the described embodiment, but should be construed in the broadest scope in accordance with the technical idea defined by the claims. ​
