Description

Technical Field

[0001] The present invention relates to a card reuse system and a card reuse method used to collect unused playing cards in a plurality of gaming tables in a casino and generate a new set of playing cards consisting of a predetermined number of decks of playing cards.

Background Art

[0002] In a casino, games using playing cards are played on gaming tables. A predetermined number of decks (for example, 8 decks) of playing cards are shuffled and packaged and provided to the gaming tables. At the gaming table, the dealer opens the package and loads the shuffled playing cards into the card shooter. The dealer draws out one playing card at a time from the card shooter to proceed with the game.

[0003] When a new shuffled playing card is loaded into the card shooter, a cut card is inserted at a position slightly before the end of the shuffled playing card. After multiple games are executed and the cut card is drawn out, the dealer replaces the shuffled playing cards in the card shooter while there are still unused playing cards in the card shooter. That is, the shuffled playing cards behind the cut card will be discarded unused (see, for example, Japanese Unexamined Patent Application Publication No. 2015-181948).

[0004] Therefore, it has been contemplated to reuse these unused playing cards. By collecting these unused playing cards from a plurality of gaming tables and creating a set of a predetermined number of decks of playing cards, a new set of shuffled playing cards can be generated.

Summary of the Invention

Problems to be Solved by the Invention

Modes for Carrying Out the Invention

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are examples of implementing the present invention, and are not intended to limit the present invention to the specific configurations described below. In implementing the present invention, specific configurations according to the embodiments may be appropriately adopted.

[0032] FIG. 1 is a schematic diagram showing the overall configuration of the card reuse system according to an embodiment of the present invention. In FIG. 1, the thick arrows indicate the movement of the playing cards, and the thin arrows indicate the transmission of information. Note that the transmission of information may be either wired or wireless.

[0033] [[ID=4C]] As shown in Figure 1, the card recycling system 100 is installed in a casino having a game floor 1 and a backyard 2. In this embodiment, the backyard 2 can be any space with security measures in place, such as restricting player access, for generating new playing card packages, and is not limited to a typical backyard.

[0034] Game floor 1 has multiple game tables 11. Each game table 11 is equipped with multiple card shooters 12 for drawing out one shuffled playing card at a time during the game. Each card shooter 12 is connected to a code reader 13, which serves as an identification information reading device for reading the set identification information attached to the set of shuffled playing cards.

[0035] As described above, at each game table 11, when a cut card is drawn from the card shooter 12, a refresh process is performed in which any unused playing cards remaining in the card shooter 12 are replaced with new shuffled playing cards. At this time, the remaining playing cards are removed from the card shooter 12. In this way, the unused playing cards removed from the card shooter 12 are collected from the game table 11 and taken to the back yard 2.

[0036] The playing cards used in the game are placed in a discard card box (not shown in Figure 1) located on the game table 12 after each game ends. The used playing cards accumulated in the discard card box are collected in the backyard 2 at an appropriate time and disposed of via a predetermined route.

[0037] In backyard 2, unused playing cards collected from multiple game tables 11 are gathered, and a predetermined number of decks (8 decks in this embodiment) of playing cards are extracted, shuffled, and packaged. The packages of shuffled playing cards thus recycled are then transported back to the game tables 11 for reuse.

[0038] Backyard 2 is equipped with an extraction device 21 that extracts a predetermined number of playing cards from multiple unused playing cards collected from multiple card chutes 12 that were not used at the game table 11, a shuffling device 22 that shuffles the predetermined number of playing cards extracted by the extraction device 21, and a set generation device 23 that generates a new playing card set from the predetermined number of playing cards shuffled by the shuffling device 22, and generates a playing card package by packaging the generated playing card set.

[0039] The extraction device 21 includes a extracted card information acquisition unit 211 that acquires information on the rank and suit of multiple playing cards extracted from each of the multiple card shooters 12, as well as information on the number of such cards; a extracted inspection device 212 that reads the rank and suit of the playing cards actually extracted from the card shooter 12 into the back hard 2 and counts the number of such cards; and a non-extracted card information acquisition unit 213 that acquires information on the rank and suit of playing cards that were not extracted from the multiple playing cards extracted from the multiple card shooters 12, as well as information on the number of such cards.

[0040] Furthermore, the backyard 2 is equipped with a management device 24 that manages the generation of playing card sets, and a storage device 25 that stores various data used by the management device 24. The management device 24, together with the retrieved card information acquisition unit 211, the retrieved inspection device 212, and the non-extracted card information acquisition unit 213, constitutes a card management system. In this card management system, the management device 24 determines whether the rank and suit information and the number of cards acquired by the retrieved card information acquisition unit 211 match the rank and suit information and the number of cards inspected by the retrieved inspection device 212. The management device 24 also determines whether the number of newly generated playing card sets and the rank and suit information and the number of cards acquired by the non-extracted card information acquisition unit 213 correspond to the rank and suit information and the number of cards acquired by the retrieved card information acquisition unit 211.

[0041] Figure 2 is a schematic diagram showing the configuration of a card shooter according to an embodiment of the present invention. The card shooter 12 is equipped with a storage section 121 for storing shuffled playing cards C. The shuffled playing cards C stored in the storage section 121 are pulled out one by one from the drawer opening 122 and used in the game. Inside the storage section 121 is a mouse 123 that functions as a weight to press the rear end of the playing card C toward the drawer opening 122, and the mouse 123 always presses the leading playing card C toward the drawer opening 122.

[0042] Near the drawer opening 122, a drawer card inspection device 124 is provided to read the rank and suit of the drawn-out playing cards C and count their number. The drawer card inspection device 124 is equipped with an ultraviolet lamp 1241 and a code detection sensor 1242. A binary code encoding the rank and suit is printed on the surface of the playing cards C (the side on which the rank and suit are indicated). This binary code is printed with ultraviolet-emitting ink that is invisible under natural light. The ultraviolet lamp 1241 irradiates the binary code of the drawn-out playing cards C with ultraviolet light, and the code detection sensor 1242 scans the binary code that has been illuminated by the ultraviolet light along the direction in which the playing cards C are drawn.

[0043] The card drawer inspection device 124 reads the rank and suit of each playing card drawn and sends the read information to the control device 125, which acts as a remaining card inspection device. The control device 125 obtains the rank and suit information of the playing cards read from the card drawer inspection device 124 and subtracts this information from the initial shuffled playing cards (8 decks) to determine the rank and suit of the playing cards C remaining in the card shooter 12, and further determines the number of remaining playing cards C.

[0044] Figure 2 further illustrates the package 50 of the shuffle playing cards. The package 50 has a barcode 51 printed on it that represents the identification information (package ID) of the package 50. A code reader 13 is connected to the card shooter 12 to read the barcode 51 on the package 50. The barcode 51 is read when a new shuffle playing card is loaded into the card shooter 12. This package ID, which is the identification information of the package, corresponds to the set identification information.

[0045] When the control device 125 removes an unused playing card C from the card shooter 12, it outputs information about the rank and suit of all remaining playing cards at that time, as well as the number of cards, along with the set identification information of the playing card.

[0046] Figure 3 is a schematic diagram showing the configuration of an extraction device according to an embodiment of the present invention. The extraction device 21 includes a stocker 214 for stocking playing cards C collected from a plurality of card shooters 12, a drawer roller 215 for drawing out playing cards C one by one from the stocker 214, an extraction reader 216 for reading the rank and suit binary codes of the playing cards C drawn out by the drawer roller 215, and a sorting device 217 that sorts the playing cards into playing cards that constitute a predetermined number of decks of playing cards C and playing cards that do not constitute a predetermined number of decks of playing cards C, based on the reading results from the extraction reader 216.

[0047] The extraction reader 216 has a configuration similar to the card inspection device 124 of the card shooter 12, and includes an ultraviolet lamp 2161 and a code detection sensor 2162. The ultraviolet lamp 2161 irradiates ultraviolet light onto the binary code on the surface of the playing card C being transported by the drawer roller 215, and the code detection sensor 2162 scans the binary code that has been illuminated by the ultraviolet lamp 2161 along the transport direction of the playing card C.

[0048] The sorting device 217 includes a rotating shaft 2171 and a guide vane 2172. The guide vane 2172 rotates on the rotating shaft 2171, causing it to move between an extraction position and a non-extraction position. When the guide vane 2172 is in the extraction position (in the example in Figure 3, the flipped-up position), the playing cards C transported by the transport roller 215 pass right by the guide vane 2172 and are sent to the extraction stocker 218, where they are stored to form a predetermined number of decks of playing cards C. When the guide vane 2172 is in the non-extraction position (in the example in Figure 3, the position where its tip touches the transported playing cards C), the playing cards C transported by the transport roller 215 are guided by the guide vane 2172 and sent to the non-extraction stocker 219 as playing cards C that are not used to form a predetermined number of decks of playing cards C.

[0049] The extraction device 21 further includes a control device 210 connected to an extraction reading device 216 and a sorting device 217. The control device 210 corresponds to the recovered card information acquisition unit 211, the extraction control unit (recovery inspection device) 212, and the non-extracted card information acquisition unit 213 shown in Figure 1. The extraction control unit 214 controls the sorting device 217 based on the reading results of the extraction reading device 216 to sort playing cards C to be extracted and playing cards C not to be extracted in order to constitute a predetermined number of playing cards in a deck.

[0050] Figure 4 shows an example of a data file containing non-extracted card information according to an embodiment of the present invention. The extraction control unit 214 updates the data file D41 based on the reading results of the extraction reader 216. Specifically, the extraction control device 212 controls the sorting device 217 to transport the playing cards C to the extraction stocker 218 if the number of extracted cards in the data file D41 has not reached a predetermined number of decks, which is 8, for the rank and suit of the playing cards C read by the extraction reader 216. At the same time, it increases the number of extracted playing cards C in the data file D41 by 1 and decreases the number of missing cards by 1.

[0051] The extraction control device 212 controls the sorting device 217 to transport the playing card C to the non-extracted stocker 219 if the number of extracted playing cards C in the data file D41 has reached a predetermined number of decks, which is 8, based on the rank and suit of the playing card C read by the extraction reader 216, and also increases the number of non-extracted playing cards in the data file D41 by 1.

[0052] The extraction control unit 212 determines whether the number of extracted cards of all ranks and suits is 8 each time it processes a playing card C, and outputs a completion report when the number of extracted cards of all ranks and suits reaches 8. At this time, the extraction stocker 218 will have 8 playing cards C of each rank and suit, for a total of 416 playing cards C. These 416 playing cards are then transported to the shuffling device 22. Playing cards C that are not extracted by the extraction device 21 are returned to the stocker 214 to form the next predetermined number of playing cards after the extraction stocker 218 has collected a predetermined number of playing cards C.

[0053] Figure 5 is a schematic diagram showing the configuration of a shuffling device according to an embodiment of the present invention. The shuffling device 22 is equipped with multiple sorting devices 221a to 221c. In the example in Figure 5, the shuffling device 22 is shown to be equipped with three sorting devices 221a to 221c, but it may be four or more stages. Since the multiple sorting devices 221a to 221c each have the same configuration, sorting device 221a will be described below, and the descriptions of sorting devices 221b and 221c will be omitted.

[0054] The sorting device 221a includes a vertically erected rail 222a, a slider 223a that can move up and down along the rail 222a, a holder 224a fixed to the slider 223a and moving up and down together with the slider 223a, a sorting roller 225a for dispensing multiple playing cards C held in the holder 224a one by one, and a shelf 226a having multiple boxes for storing the playing cards C dispensed from the holder 224 by the sorting roller 225a. In the example in Figure 5, the shelf 226a has six boxes, but the number of boxes is not limited to this.

[0055] The sorting device 221a further includes a control device (not shown), and the slider 223a and sorting roller 225a are driven under the control of the control device. The control device is given a random number and determines which box on shelf 226a to place the items in according to the random number.

[0056] The set of playing cards C, consisting of a predetermined number of decks (8 decks), extracted by the extraction device 21, is first loaded into the holder 224a of the first-stage sorting device 221a. Once all the playing cards C are sorted into one of the boxes, the cards sorted into each box are stacked from top to bottom and loaded into the holder 224b of the second-stage sorting device 221b. By repeating this process, the set of playing cards C, consisting of a predetermined number of decks (8 decks), is shuffled.

[0057] The playing cards C, sorted into multiple boxes in the final stage of the shuffling device 22, are stacked from top to bottom and transported to the set generating device 23. The set generating device 23 also functions as a packaging device, loading the 416 shuffled playing cards C into boxes, sealing the boxes, and creating a package with shrink film. The package containing the thus regenerated shuffled playing card C sets is then transported back to the game table 11 for use in the game.

[0058] As described above, the set generation device 23 generates a new playing card set from a predetermined number of playing cards shuffled by the shuffling device 22. At this time, the management device 24 assigns set identification information to the new playing card set generated by the set generation device 23 to identify the playing card set. The set generation device 23 also functions as a packaging device that loads the new playing card set into a card package. Once the playing card set in the card package is loaded into the card shooter 12, the new playing card set is used on the game table 11.

[0059] When the set generation device 23 assigns set identification information to a new playing card set, the management device 24 associates this set identification information with the set identification information of the multiple playing cards used to generate the new playing card set, which was acquired by the retrieved card information acquisition unit 211, and stores it in the storage device 25. To this end, the retrieved card information acquisition unit 211 of the extraction device outputs the set identification information of a playing card to the management device 24 each time an unused playing card is supplied to the extraction device 21 from a card shoe 12. The management device 24 accumulates the set identification information output from the extraction device 21 in this manner until a new playing card set is completed. When a new playing card set is generated by the set generation device 23, the management device 24 refreshes the accumulated set identification information by associating all the set identification information of the unused playing cards used to generate the new playing card set with the set identification information of the new playing card set.

[0060] As described above, a new package of shuffled playing cards is generated using the playing cards C recovered from multiple card shooters 12. However, the card recycling system 100 of this embodiment has a function to check whether there are any shortages of playing cards C due to loss, theft, etc., between the recovery of the playing cards C and the generation of the new package. This check is performed by control of the management device 24.

[0061] First, the card recycling system 100 has a function to confirm that the playing cards C collected from the card chutes 12 of the multiple game tables 11 have been transported to the extraction device 21 in the backyard 2 without any shortages. For this purpose, as described above, the control device 125 of the card chutes 12 outputs information on the rank and suit of the remaining playing cards that are collected without being used, as well as information on the number of such cards, along with the set identification information of the playing cards, and the collected card information acquisition unit 211 of the extraction device 21 acquires this information.

[0062] Figure 6 shows an example of a data file for recovered card information according to an embodiment of the present invention. The data file D61 illustrated in Figure 6 is provided from the card shooter 12 to the extraction device 21, and the extraction device 21 acquires this data file D61. The recovered card information shown in data file D61 includes information on the rank of the recovered playing cards C, the number of cards of each suit, and the total number of cards. The extraction device 21 provides the acquired recovered card information to the management device 24, and the storage device 25 stores the recovered card information in association with its set identification information.

[0063] Furthermore, as described above, the extraction control unit 212 of the extraction device 21 acquires the rank and suit of each of the collected playing cards C in order to determine which playing cards to extract. The extraction control unit 212, acting as a collection inspection device, outputs the number of cards of each rank and suit, as well as the total number of cards, read by the extraction reading device 216, to the management device 24.

[0064] For this inspection, the stocker 214 of the extraction device 21 holds a playing card C for each card shooter 12 that has collected an unused playing card C, that is, for each set identification information of the collected playing cards. The management device 24 checks whether the collected card information corresponds to the rank and number of cards per suit and the total number of cards input from the collection inspection device 212 for each set identification information.

[0065] Furthermore, when a predetermined number of playing cards C are extracted by the extraction device 21, the management device 24 checks whether the number of playing cards C of each rank and suit that were not extracted is correct in light of the recovered card information acquired by the recovered card information acquisition unit 211. In other words, the management device 24 checks whether there is a shortage of playing cards C when the extraction device 21 extracts a predetermined number of playing cards.

[0066] For example, if a predetermined number of playing cards are extracted through 10 collections of playing cards, the management device 24 checks whether the number of cards per rank and suit obtained by subtracting the number of cards per rank and suit (8 cards) for a predetermined number of decks (8 decks) from the sum of the information of collected cards related to these 10 collections stored in the storage device 25 matches the number of cards per rank and suit of multiple playing cards C that the extraction control unit 212 determined not to have been extracted.

[0067] In other words, the management device 24 checks whether the total number of cards per rank and suit (8 cards each) of the extracted predetermined number of decks (8 decks) of playing cards C, plus the total number of cards per rank and suit of the multiple playing cards C that were determined not to have been extracted, matches the total of the collected card information related to multiple collections acquired by the collected card information acquisition unit 211.

[0068] This allows for checking whether there are any shortages when sorting the multiple playing cards C collected through multiple collections into those to be extracted / not extracted in order to constitute a predetermined number of playing cards C in a deck.

[0069] For this inspection, the non-extracted card information acquisition unit 213 acquires information on the rank and number of cards of each suit of playing cards C that have been determined not to be extracted, based on the extraction decision made by the extraction control unit 212, as non-extracted card information, and outputs this to the management device 24.

[0070] When a predetermined number of playing cards C have been extracted, the management device 24 checks whether the extracted card information input from the extracted card information acquisition unit 211 corresponds to the non-extracted card information input from the non-extracted card information acquisition unit 213.

[0071] Figure 7 is a flowchart of a card recycling method according to an embodiment of the present invention. In the card recycling method, first, multiple unused playing cards are collected from the card shooter 12 into the backyard 2 (step S71). Then, the extraction device 21 extracts a predetermined number of playing cards from the collected multiple unused playing cards, and at that time outputs set identification information of the multiple unused playing cards to the management device 24 (step S72). Next, the shuffling device 22 shuffles the predetermined number of playing cards extracted by the extraction device 21 (step S73).

[0072] The set generation device 23 generates a new playing card set from a predetermined number of playing cards shuffled by the shuffling device 22, and assigns set identification information to the new playing card set (step S74). Then, the management device 24 associates the set identification information obtained from the retrieved card information acquisition unit 211 with the set identification information assigned to the new playing card set by the set generation device 23 and stores it in the storage device 25 (step S75).

[0073] In the above embodiment, the non-extracted card information acquisition unit 213 acquired the rank and suit information of the playing card C that the extraction control device 212 determined not to be extracted as non-extracted card information. However, instead, the non-extracted card information acquisition unit 213 may acquire non-extracted card information by reading the rank and suit of multiple playing cards C stocked in the non-extracted stocker 219.

[0074] Furthermore, in the above embodiment, the management device 24 checked whether the retrieved card information and the unextracted card information corresponded when a predetermined number of playing cards C were extracted. Alternatively, the management device 24 may check, for each retrieval (i.e., for each set identification information), whether the sum of the number of playing cards C by rank and suit extracted by the extraction device 21 and the number of playing cards C by rank and suit that were not extracted corresponds to the retrieved card information.

[0075] In the above embodiment, the management device 24 determined whether the information on the number of cards per rank and suit acquired by the recovered card information acquisition unit 211 matched the number of cards per rank and suit inspected by the recovered inspection device 212, and also determined whether the number of newly generated playing card sets and the number of cards per rank and suit acquired by the non-extracted card information acquisition unit 213 corresponded to the number of cards per rank and suit acquired by the recovered card information acquisition unit 211. However, instead, the management device 24 may determine only whether the number of cards matches. That is, the management device 24 may determine whether the information on the number of cards acquired by the recovered card information acquisition unit 211 matched the number of cards inspected by the recovered inspection device 212, and also determine whether the number of newly generated playing card sets and the number of cards acquired by the non-extracted card information acquisition unit 213 corresponded to the number of cards acquired by the recovered card information acquisition unit 211.

[0076] Furthermore, in the above embodiment, the management device 24 checked whether there were any shortages between collection and recycling by inspecting the rank and suit of the playing cards C and their total number. However, the management device 24 may also check whether there are any shortages by inspecting the rank and suit of the playing cards C, or the management device 24 may check whether there are any shortages by inspecting only the number of playing cards C.

[0077] Furthermore, in the above embodiment, the reading results of the cards drawn out one by one by the card shooter 12 were subtracted from the initial shuffled playing cards to obtain information on the suit, rank, and number of remaining (recovered) playing cards as recovered card information. However, instead, recovered card information may be obtained by a recovered card reader that reads the playing cards to be recovered, or by a discarded card reader that reads the discarded cards used in the game and discarded.

[0078] The retrieved card reader reads the rank and suit of the playing cards one by one as they are fed in, using the same configuration as the drawn card inspection device 124. Alternatively, the card shooter 12 may be used as the retrieved card reader. In this case, the card shooter 12 is set to retrieved card reading mode, and the rank and suit of the cards to be retrieved are drawn out one by one, allowing the drawn card inspection device 124 to read them.

[0079] When reading discarded cards, a discard slot is provided on the game table 11, and the rank and suit of the playing cards that have been inserted into the discard slot after being used in the game are read using the same configuration as the card drawer inspection device 124.

[0080] In the above embodiment, the rank and suit information was printed on the playing cards in binary code format using ultraviolet-emitting ink. However, instead of ultraviolet-emitting ink, the information may be printed using ultraviolet-absorbing ink that becomes visible when irradiated with infrared light. Alternatively, instead of printing with these invisible inks, the rank and suit marks printed on the playing cards may be photographed, and the rank and suit may be read by image analysis.

[0081] Furthermore, in the above embodiment, the management device 24 determined whether the number of newly generated playing card sets and the rank and suit information and number information acquired by the non-extracted card information acquisition unit 213 corresponded to the rank and suit information and number information acquired by the recovered card information acquisition unit 211. Alternatively, the management device 24 may determine whether the number of newly generated playing card sets and the rank and suit information and number information acquired by the non-extracted card information acquisition unit 213 corresponded to the rank and suit information and number information inspected by the recovered inspection device 212.

[0082] Furthermore, in the above embodiment, multiple playing cards of a predetermined number of decks extracted by the extraction device 21 were shuffled by the shuffling device 22 and then packaged by the packaging device 23. However, this shuffling by the shuffling device may be omitted. That is, since the unused playing cards that are collected have already been shuffled, it is considered that the randomness of the order of these playing cards is not lost even when such unused playing cards are collected from multiple card shooters 12 and a new set of multiple playing cards of a predetermined number of decks is extracted. Therefore, the shuffling device 22 may be omitted.

[0083] Furthermore, in the above embodiment, the card management system had a function to check whether any playing cards were lost before they were collected and reused. However, this specification also discloses card reuse systems that do not have such a function.

[0084] Furthermore, in the above embodiment, the extraction device 21 was configured to read the rank and suit in order to extract a predetermined number of playing cards in order to check whether the rank, suit, and number of playing cards actually collected in the backyard matched the collected card information. However, instead, a collection inspection device may be provided in the backyard, separate from the extraction device 21, to check whether the rank, suit, and number of playing cards actually collected in the backyard matched the collected card information.

[0085] Furthermore, in the above embodiment, the extraction device 21 was configured to extract only one set of multiple playing cards of a predetermined number of decks. However, instead, the extraction device 21 may be composed of multiple stages, including a first stage and a second stage. In this case, the second stage extracts multiple playing cards of a predetermined number of decks from playing cards that were not extracted in the first stage as playing cards that do not constitute multiple playing cards of a predetermined number of decks.

[0086] Furthermore, in the above embodiment, the extraction device 21 performed the extraction process for each set of playing cards recovered from one card shooter 12. However, multiple playing cards recovered from multiple card shooters 12 may be placed into the stocker 214 simultaneously and the extraction process performed thereafter. Alternatively, multiple playing cards recovered from the card shooters 12 may be added to the stocker 214 while the extraction device 21 is performing the extraction process.

[0087] Furthermore, the extraction device 21 may have a function to inspect the quality of the playing cards one by one during the processing process, and may not extract playing cards that do not meet a predetermined quality standard. The quality of the playing cards inspected here may include, for example, the presence or absence of creases, scratches, oil stains (from fingers), etc.

[0088] Furthermore, in the above embodiment, the non-extracted card information acquisition unit 213 acquired information on the rank and suit and the number of non-extracted playing cards by calculating by subtracting the extracted rank and suit from the rank and suit of the collected playing cards. However, instead, information on the rank and suit and the number of non-extracted playing cards may be acquired by using a device that reads the rank and suit of the non-extracted playing cards.

[0089] In the above embodiment, a new playing card set is provided to the card shooter 12 in package form, and the package is opened and the playing card set is removed and loaded into the card shooter 12. Alternatively, the card shooter 12 may adopt a cartridge system. In this case, the storage section 121 of the card shooter 12 is a cartridge that can be attached to and detached from the card shooter 12, and the cartridge is replaced when refreshing. For this purpose, a new playing card set is provided to the game table 11 in a cartridge, and when refreshing, the cartridge containing the new playing card set is attached to the card shooter 12 in place of the cartridge that was previously attached to the card shooter 12.

[0090] The cartridge is equipped with a locking mechanism to prevent playing cards from being removed or added during transport. The lock mechanism is released when the cartridge is inserted into the card chute 12. When unused playing cards are transported to the extraction device 21 in the backyard 2, a cartridge is used, and in this case as well, the cartridge is locked by the locking mechanism during transport. The set generation device 23 loads newly generated playing card sets into cartridges instead of packaging them in packages, and locks the cartridge's locking mechanism.

[0091] Just as set identification information is printed on the package, this cartridge is also assigned set identification information. Furthermore, to allow for repeated use of the cartridge, the set identification information is assigned to the cartridge in a rewritable format. For example, a piece of paper with the set identification information printed on it is attached to the cartridge.

[0092] Furthermore, in the above embodiment, when unused playing cards are recovered from the card shooter 12, set identification information of the unused playing cards is provided from the card shooter 12 to the extraction device 21. However, instead of this, or in addition to this, shooter identification information for identifying the card shooter 12 may be provided from the card shooter 12 to the extraction device 21.

[0093] In this case, the management device 24 stores in the storage device 25, in place of, or in addition to, the set identification information acquired by the recovered card information acquisition unit 211, which is the set identification information of the multiple card shooters that recovered the multiple playing cards used to generate the new playing card set, in association with the set identification information of the new playing card set.

[0094] Furthermore, in the above embodiment, the management device 24 associated the set identification information of the new playing card set with the set identification information of the multiple playing cards used to generate the new playing card set, which was acquired by the recovered card information acquisition unit 211. Alternatively, the management device 24 may associate the set identification information of the new playing card set with the set identification information of the multiple playing cards that could have been used to generate the new playing card set, which was acquired by the recovered card information acquisition unit 211.

[0095] In other words, in the above embodiment, multiple unused playing cards recovered from a single card shoe 12 are supplied together to the extraction device 21. At that time, the extraction device 21 reports set identification information of the multiple unused playing cards to the management device 24. The management device 24 stores the set identification information of the unused playing cards used until a new playing card set is generated by the set generation device 23. When a new playing card set is generated by the set generation device 23, all the set identification information that has been stored up to that point is associated with the set identification information of the newly generated playing card set. Alternatively, a less stringent management system may be used.

[0096] In other words, without strictly managing the set identification information of unused playing cards supplied to the extraction device 21, the management device 24 may associate the set identification information of unused playing cards supplied to the extraction device 21 with the set identification information of new playing card sets generated by the set generation device 23 during a certain period (for example, one day). Alternatively, the management device 24 may associate the set identification information of unused playing cards collected in the backyard 2 during a certain period with the set identification information of new playing card sets generated by the set generation device 23 during a certain period. In other words, unused playing cards in the set identification information associated with the set identification information of new playing card sets generated by the set generation device 23 are not necessarily included in the new playing card set. Alternatively, a new playing card set having set identification information associated with the set identification information of unused playing cards is not necessarily included in the new playing card set.

[0097] Furthermore, the management device 24 may associate the set identification information of the new playing card set with the shooter identification information of the multiple card shooters 12 that retrieved multiple playing cards that could have been used to generate the new playing card set, which was acquired by the retrieved card information acquisition unit 211.
