The present invention relates to a card disposition system for a table game that is able to prevent cards used in a card game from being fraudulently brought out, and has a function of detecting whether or not a predetermined number of cards are sufficiently disposed of.
A fraud at the game table is conceivable where a player replaces a card with another card during a game to provide an advantageous game condition for him/her. An example of apparatuses for preventing such a fraud is disclosed in US 2006-0247036A1. In this patent literature, it is determinable whether the cards appeared in the table game are the same as those used in the determination of the winners/losers of each of the game, thereby preventing any fraudulent actions in card games. The apparatus proposed therein prevents fraud by detecting whether or not a card dealt on the game table has been replaced with a false card and was used in determining the winners/losers of the game (see Patent Literature 1).
In order to replace any card during a game, it is necessary to obtain cards of the same type as those used in the relevant casino in advance. In many cases, cards used in a table game are collected at the end thereof, but those collected cards are combined into another card set for reuse. Thus, there is a risk that someone may obtain such cards for the purpose of committing fraud during the course of such re-combination of card sets.
With conventional apparatuses, it is not possible to dispose of all of cards, without any omission, that were used on the game table while concurrently confirming that there are a predetermined number of cards (for example, in the case where eight decks of cards are used, there should be 416 cards (52 cards×8 decks)). Also, generally at the game table, after the cut card is drawn, the set of cards that has been used in that game will no longer be used. However, unless the unused cards of that card set are sufficiently disposed of such cards may again be fraudulently brought out.
The present invention has been made in view of the above problem, and aims to provide a card disposal system that enables a perfect disposal operation in which disposal of cards that are to be discarded after the use thereof on the game table is performed only after confirming that the predetermined number of cards are all there (for example, in the case where eight decks of cards are used, there should be 416 cards (52 cards×8 sets)). Also, the system is capable of making a void hole or a notch on the cards after verifying the number of cards to make it impossible to reuse such cards, thereby completely preventing any fraudulent reuse of such cards.
To solve the above conventional problems, the present invention provides a card disposal system for disposing of cards that are housed in a card dealing apparatus (dealing shoe) placed on a game table and manually dealt onto the game table after the use thereof in a game, the card disposal system including: a set of cards made up of a plurality of decks of cards that can be housed in the dealing shoe; and a card disposal apparatus for disposing the cards collected,
wherein a cut card for stopping a game is included in the set of cards, the card disposal apparatus includes:
a discharge opening for receiving a card to be disposed of;
a number counter for counting and storing the number of cards received from the discharge opening;
a voiding means for making a void hole or a notch on a card placed in the discharge opening;
a disposed card stocker for receiving a card that has passed through the voiding means in a disposed card carton; and
a deck examination means for determining whether the number of cards placed in the discharged opening matches the number of cards corresponding to a predetermined number of decks, the discharge opening sequentially receives the cards that are used in each game and thereafter get collected therein, and is configured to be capable of receiving all cards left unused in the dealing shoe when the game is stopped at a predetermined time after the cut card is drawn from the dealing shoe, the deck examination means adds the number of cards used in each game, that number being counted by the number counter, and the number of the cards left unused in the dealing shoe at the predetermined time after the cut card is drawn from the dealing shoe, and determines whether the number of the cards disposed of matches the number of cards corresponding to a predetermined number of decks, and
the disposed card stocker has a closed passage for disposed cards with which no card can be removed after it is placed in the discharge opening before it reaches the disposed card carton.
In addition, with the card disposal system for a table game of the present invention that solves the conventional problems, the disposed card carton of the disposed card stocker is configured to be capable of housing a scrap generated from making the void hole together with the card to be disposed of in the disposed card stocker.
With the card disposal system for a table game of the present invention, it is possible to detect the incorporation of any false cards, and furthermore, to examine whether with respect to the cards that have been put inside a discharge opening, there are a predetermined number of genuine cards for each number (rank), thereby confirming that the cards used in a table game on the game table are a complete set of genuine cards that include the predetermined number of cards for each number (rank).

a), 10(b), 10(c) and 10(d) are perspective views of the card disposal apparatus each illustrating the procedure for attaching and removing a disposed card carton to and from a disposed card stocker of the card disposal apparatus.
Embodiment 1 of the present invention will be described with reference to the attached drawings. In
A cut card 3c is inserted in a set 3s of cards 3 (a card set 3s) before the card set 3s is set in the dealing shoe 200 on the game table 2. The cut card 3c is inserted at any place within the latter half portion of the card set 3s when used in a game (in the last quarter or one-fifth of the card set 3s). The cut card 3c is used to end a game at the game table 2 leaving about 20 to 40 cards 3 in the dealing shoe 200, so as to prevent any player from counting the ranks of the cards dealt during a game to predict the ranks of the cards when the number of the cards that have not been dealt yet becomes small. The plan view of the cut card 3c is shown in
The card disposal apparatus 1 is configured such that it sequentially receives the cards 3a used and collected in each game, and can receive all of cards 3r that are left unused in the dealing shoe 200 when the game is stopped at a predetermined time after the cut card 3c comes out of the dealing shoe 200 (at the next game, or a few games after the drawing of the cut card 3c). With a deck examination means to be described below, the card disposal device 1 adds the number of cards 3a that were used in each game, and the number of the cards 3r that are left unused in the dealing shoe 200 at a predetermined time after the drawing of the cut card 3c from the dealing shoe 200, and determines whether the total number of the disposed cards matches the number of cards corresponding to the predetermined number of decks.
Next, the card disposal apparatus 1 will be described in detail with reference to
The card disposal device 1 also includes a deck examination means 13 that counts the number of cards 3 at least for each number (rank) by integrating the information acquired from the disposed card information acquiring means 6 and the information of the card counter 8, thereby determining whether the number of the cards 3 put in the discharge opening 4 matches the predetermined number. The card disposal device 1 includes a control device 14 that performs an overall control of the card disposal device 1. Each means described above is arranged in the control device 14, which controls the operations thereof. The control device 14 is configured with an electronic circuitry that includes a microcomputer, memory and the like, and has the configuration of a general computer, such as a CPU, ROM, RAM or the like. The control device 14 performs the overall control of the card disposal device 1 by executing programs stored in the ROM or other memories, thereby performing the necessary processing.
A feed roller 15 for feeding the cards 3 to be disposed of one by one from the disposed card receiving board 5 is provided below the disposed card receiving board 5. The feed roller 15 is rotatively driven by a drive motor 16. The drive motor 16 is a stepping motor. When a card 3 is placed on the disposed card receiving board 5, a card sensor 17 detects the card 3. Then, the control device 14 controls the drive motor 16 to rotate the feed roller 15. In this manner, the feed roller 15 feeds the card 3 on the disposed card receiving board 5. The card 3 being fed by the feed roller 15 is moved forward in the direction of a disposed card stocker 19 (the arrow D) by a pair of forwarding rollers 18. The movement of the forwarding rollers 18 is controlled by a feed motor 16f. The moving speed of the forwarding rollers 18 is set such that the card 3 is forwarded in a speed faster than the speed in which the feed roller 15 feeds the card 3, and thus the card 3 is drawn by the forwarding rollers 18 and forwarded toward the disposed card stocker 19 (the arrow D) for certain. The information on the forwarded card 3 is detected and acquired by a group information acquiring sensor 20 and by two card information acquiring sensors 21.
The group information acquiring sensor 20 is connected to the group information acquiring means 7 that acquires the group information from the card 3. Also, the card information acquiring sensors 21 are connected to the disposed card information acquiring means 6 that acquires the information of the number (rank) of the card 3, thereby acquiring the number (rank) information. Each card 3 that is forwarded to the disposed card stocker 19 is detected by the card counter 8, and the number of cards 3 that passes through is counted. The signal of the group information acquiring sensor 20 is transmitted to the group information acquiring means 7. The authenticity determination means 9 compares the group information of the card 3 acquired by the group information acquiring means 7 with predetermined group information stored in advance, thereby determining whether the group information of the card 3 matches the predetermined group information. If the authenticity determination means 9 determines that the group information of the card 3 does not match the predetermined group information, that card 3 is determined to be a false card, and the control device 14 lights a display lamp/display lamps 22 through the output means 10 that outputs the determination results, and transmits the presence of any false card to a management division or the like of a casino or the like.
When any card 3 is determined to be a false card by the authenticity determination means 9, the control device 14 transmits such information to a voiding means (to be described later). The card 3 whose determination has been made by the authenticity determination means 9 is forwarded to the disposed card stocker 19. The card disposal device 1 has a closed passage for disposed cards with which no card 3 can be removed before it reaches a disposed card carton 19c of the disposed card stocker 19.
The information on the card 3 is acquired by the card information acquiring sensors 21 and the group information acquiring sensor 20 while it is forwarded to the disposed card stocker 19. After the card 3 is determined to be a genuine card, a void hole H is made by a voiding means 26 such that the card 3 cannot be used anymore. For this purpose, each card 3 forwarded to the disposed card stocker 19 passes through the void means 26. The void means 26 makes a void hole H on the card 3 with a hole-making means (such as a punch and a die, which are not shown in the drawings but will be described later). A card 3h with a void hole H then falls inside the disposed card carton 19c of the disposed card stocker 19, and is received by the disposed card carton 19c made of paper or plastic that is provided in the disposed card stocker 19. In Embodiment 1, the void hole H is created by the void means 26, but a configuration is also possible in which a notch C is formed on a corner of the card 3. In this manner, a void hole or notch is made on the card such that it cannot be reused after the disposal process and the checking of the number of the cards, thereby completely preventing the fraudulent reuse thereof. Note that a disposed card lock means 27 is provided in the disposed card carton 19c to prevent the fraudulent removal of any card 3, and a fraud preventing device 25 of the control device 14 controls the disposed card lock means 27 such that only authorized operators can remove the disposed card carton 19 with a key or the like.
The disposed card carton 19c is removed frontward in the direction perpendicular to the drawing in
The disposed card carton 19c of the disposed card stocker 19 can be attached/detached to/from the disposed card stocker 19, and is made of paper or a plastic material so as to be capable of being disposed of or shredded by a shredder or the like while containing the disposed cards 3h inside. Therefore, it is possible to dispose of the disposed card carton 19c with the disposed cards 3h, which makes the disposal operation simple and economic.
The deck examination means 13 will be described next. Generally, a plurality of decks (4, 6, or 8 decks) of cards are set in the dealing shoe 200 (electronic shoe) that is placed on the game table 2. Although the cards inside the dealing shoe 200 are dealt in each game, all the cards are never used up. The cut card (not shown) or the like is inserted in the plurality of decks (4, 6, or 8 decks) of cards in the dealing shoe 200 for security purposes, and when the cut card is drawn, the cards inside the dealing shoe 200 will no longer be used. All of remaining cards 3r are placed in the discharge opening 4 for disposal.
The information on the number (rank) is acquired from these remaining cards 3r by the disposed card information acquiring means 6. The deck examination means 13 combines the information of the number (rank) acquired through the disposed card information acquiring means 6 from the remaining cards 3r with the already-acquired information of at least the number (rank) of the cards 3a used in the games. Then, the resulting information and the information from the card counter 8, which serves as the number counting means, are used in an integrated manner so as to obtain the number of cards for each number (rank) of the cards. Thereafter, with respect to all the cards 3 that are placed on the game table and then placed in the discharge opening 4, it is determined whether, for each number (rank), the number of cards matches the number corresponding to a predetermined number of decks (whether there are 32 cards (4 suits×8 decks) for each number, from Ace to King).
The total number of the cards 3 used in a table game is determined in advance in a casino or the like (normally, 4, 6, 8, 10 or 12 decks). For example, in the case of 8 decks, of the 416 cards 3 (52 cards×8 decks), there are 8 cards that will have the same suit and rank. In the control device 14, the deck examination means 13 determines whether there are a predetermined number of cards 3 for all combinations of a certain rank and a certain suit. Then, through the output means 10 that outputs the results of determination, the display lamp/display lamps 22 is/are lighted in different colors depending on the results of the determination, and at the same time, the counting result of the number of cards 3 is transmitted to a general management division or the like 201 through a communication means 202.
When the cards 3 that were already disposed of in the disposed card stocker 19 and the cards 3 that were not used in the game but were collectively placed on the disposed card receiving board 5 of the discharge opening 4 (which are also to be forwarded to the disposed card stocker 19) are added, it is expected that the total number of the cards 3 will be 416, which corresponds to the number of cards 3 that were first set in the dealing shoe 200 (52 cards×8 decks). In the case of a card set that includes 8 decks of cards, the deck examination means 13 determines whether there are 32 cards for each of the 13 ranks (in total, 416 cards) based on the information obtained from all of the 416 cards (52 cards×8 decks).
Next, the cards 3 used in the card disposal system for the table game according to the embodiments of the present invention will be described. For each card 3, a code 102 by which the number of the card 3 is encoded and which is composed of marks M that are invisible under normal conditions is placed on the upper side and the lower side of the card 3 in a point-symmetric manner. The code 102 is configured by a combination of the number and the arrangement of the plurality of marks M printed in infrared or ultraviolet reactive ink or the like that are invisible in daylight. Also, the card 3 includes a group code information 103 that is used as an authenticity determination code, and the group code information 103 is created by coding information that indicates the authenticity of the card, and arranging the coded information by printing or the like so as to be invisible under normal conditions (for example, in ultraviolet reactive ink). The code 102 and the group code information 103 are arranged in at least two positions on the card 3 in a point-symmetric manner using the center of the card 3 as reference.
The code 102 is read by the two card information acquiring sensors 21 that configure the card information acquiring sensor 21. The card information acquiring sensor 21 is configured to produce an output signal upon detection of a Mark M (a known ultraviolet responsive optical sensor or the like is used). The relation between the marks M and the output of the on signals from the two UV sensors (the output of electrical signals produced when the code 102 configured by the marks M is read) are shown in
Next, the authenticity determination means 9 will be described, the authenticity determination means 9 determining the authenticity of a card 3 based on the information relating to its authenticity. As described above, a card 3 whose authenticity is to be examined includes a group code information 103 serving as the group information; the group code information 103 is created by encoding information that indicates the authenticity of the card 3, and is formed so as to be invisible under normal conditions (for example, in ultraviolet reactive ink). The group code information 103 is a substance or material (such as an ink or paint material) itself that emits, as a code, light rays of different wavelength spectra when irradiated with light rays of different wavelengths. The group information acquiring sensor 20 emits invisible light rays of different wave lengths onto the group code information 103, and receives light rays of at least two different wave lengths emitted by the group code information 103. Then, the authenticity determination means 9 has a function of determining whether the ratios of the intensities of these light rays are the same, thereby determining the authenticity of the card 3. A configuration is also possible in which light rays of different wavelength spectra are received and two or more light rays of more complex wavelengths are analyzed.
A polymer material, DNA material or the like that has a molecular structure with which a light ray of a specific wavelength is emitted against light is used as a substance or material that emits light rays of different wavelength spectra against invisible light rays of different wavelengths (ultraviolet ray, infrared ray, etc.); this serves as the group information. A polymer material that has a molecular structure with which a light ray of a specific wavelength against is emitted against light is printed in the upper and lower edges of the card 3 as shown in
The group code information 103 that serves as the group information is printed independently and in the same position at least for each unit of a card deck, as described above. However, a configuration is also possible in which the group code information 103 is configured using a certain substance or material that serves as a code, and such a substance or material is contained in a coating material, anchor coating material, in the ink to print the back pattern, mark, index, or the code to indicate the number of the mark on the surface of the card. When the group code information 103 is read, the group information acquiring sensor 20 emits two types of ultraviolet rays, irradiates the group code information 103 printed on the card 3 with the rays, and receives the light rays of different wavelength spectra emitted by the group code information 103. The control device 14 including the authenticity determination means 9 is configured with an electronic circuitry that includes a microcomputer, memory and the like; has the configuration of a general computer, such as a CPU, ROM, RAM or the like; and performs the processing to determine the authenticity of the group code information 103.
Embodiment 2 of the table game system of the present invention will be described in detail below. In Embodiment 2, the same reference numerals are assigned to the same configurations and elements used in Embodiment 1, so the description thereof will be omitted.
Next, the card disposal apparatus 350 of Embodiment 2 will be described. The card disposal apparatus 350 of Embodiment 2 is placed on the game table 2 or on a side surface thereof. Cards 3 are disposed of through a disposal opening 354 after they are used in a game. A weight 356 is placed above a disposed card receiving board 355 for receiving cards 3 to be disposed of. The weight 356 is placed to assist the feeding roller 15 such that the feeding roller 15 can sufficiently feed a card 3 even if the card 3 to be disposed of has been bent or the like during the game; the front and rear portions of the card 3 are pressed downward by weight rollers 357 and 358. The weight 356 receives the card 3 from the direction indicated by the arrow P into the discharge opening 354, as shown in
The card 3 being fed by the feed roller 15 is moved forward by a pair of forwarding rollers 18 in the direction of a disposed card stocker 359. The card information acquiring sensors 21 for the disposed card information acquiring means 6, which acquire the information of the number (rank) from the card 3, are placed in the disposed card receiving board 355. The card information acquiring sensors 21 and the group information acquiring sensor 20 respectively acquire information from the card 3 before the card 3 is forwarded to the disposed card stocker 359.
As described above, once the cut card 3c is drawn, only a predetermined number of games are played thereafter, and then the cards 3r left unused at the end of such games are no longer used and removed from the dealing shoe 200. The remaining cards 3r are then placed in the discharge opening 354 at one time (as shown in
A punching device 360 is provided between the feeding roller 15 and the forwarding rollers 18 as a voiding means for making a void hole H on the card 3. If a card 3 is determined to be a genuine card, a single void hole H is made on the card 3 (an example of which is shown in
The cards 3h that have had a void hole H made thereon fall inside the disposed card carton 19c of the disposed card stocker 359. The cards 3h that have had a void hole H made thereon by the punching device 360, which serves as a voiding means, are received by the disposed card carton 19c that is made of paper or plastic and provided in the disposed card stocker 359.
Next, the punching device 360 will be described in detail with reference to
The attachment and removal of the disposed card carton 19c to and from the card disposal apparatus 350 will be described below. The disposed card carton 19c is inserted to the card disposal apparatus 350 from the top as shown in
After the fraud detection means 12 has determined that the disposed card carton 19c of the disposed card stocker 19 is normal, and the deck examination means 13 has confirmed that the number of the cards matches the number of cards corresponding to a predetermined number of decks, an OK display (19d) as the result of the determination of the deck examination means 13 is exhibited, as shown in
The above is a description of Embodiments 1 and 2 of the present invention. As a variation of the present embodiments, the group code may be printed on the card 3 in a similar manner to that of the mark M or the group code information 103. The group information, which indicates the group of the group code, may be different for each deck or for each plurality of decks of cards 3. The group information may be differentiated for each casino or table where the cards are used, or for any other unit. The group information may be different for each card supply source (card shoe or the like). In addition, a different group code may be set for each manufacturing lot, or each casino that uses the cards.
In the embodiments described above, a polymer material is printed on the genuine cards 3 as the group code information 103. However, in order to configure the authenticity determination code in a more complicated manner, a configuration may be adopted in which a card further includes a group code that contains the group information, which indicates the group of the card, and the authenticity determination code is printed within that group code. In this case, a configuration is possible in which such group code is read by a code reading unit that reads the code indicating the number of the card, or a configuration is also possible in which such group code is read by the group information acquiring sensor 20 of an authenticity determination unit from the authenticity determination code that indicates the authenticity of the card, and the group code is determined or distinguished by the authenticity determination unit.
It is also possible to configure the authenticity determination code in an additionally complicated manner through the improvement of the present embodiments by the following method: two or more substances such as polymer materials are selected, such selected substances whose reflected light rays have mutually different spectra are then used in combination, and the resultant complex is thereafter used as the authenticity determination code. Although an invisible ultraviolet responsive material and a UV sensor for detecting that material are used in the present embodiments, such invisible ultraviolet responsive material is an example of the group code information 103 that cannot be read by human eyes but may only be read under a prescribed condition. Accordingly, an infrared responsive material that is invisible to the human eye may be used instead. The group code information 103 of the playing cards may also include such information that is unique to the casino where the playing cards are used, or unique to each table in the casino or each seller of the playing cards.
Next, the card disposal system of further embodiment will be described with
The card disposal apparatus 350 for disposing the cards in this further embodiment has the same configuration as the embodiment 2 and this has the same number in
When the dealing shoe 200 reads the cut card 3c the dealer at the game table stops using the set of cards 3s in the dealing shoe 200. At this timing the deck examination means 405 examines whether or not each numbers of the cards which have the same rank match the numbers of the cards in every ranks sent by the dealing shoe 200 through a communication means 406 with every numbers of cards which have the same rank each received by the discharge opening 354 and outputs the result of the examination. (if there is a mismatch or not) together with the card ID 403 to the main frame of a central computer system 400 through communication means 406 or through the dealing shoe 200) to casinos or administrative sections.
When the timing comes that they have to change whole set of cards in the dealing shoe 200 after cut card has drown to the table and all the cards of the set of cards 3s received by the discharge opening 354, the deck examination means 405 examines whether or not each numbers of the cards in every ranks received by the discharge opening 354 have the same ranks with predetermined numbers for predetermined decks sets (8 decks etc.) and outputs the result of the examination together with the card ID 403 to the main frame of a central computer system 400 through communication means 406 or through the dealing shoe 200) to casinos or administrative sections.
In the embodiments there is 256 types of codes (4×4×4×4). Fifty two (52, 13 ranks×4 suits) playing cards are each assigned one of the 256 codes, and the relations of such assignment are stored in a memory or by a program as an association table. As to the code 102, identify at least the number (rank) of the card 3 based on that predetermined association table (not shown) and the relation between each association table or database is recorded in association with the shuffled card ID (403) and one of the plurality of association tables or databases is identified by identifying the shuffled card ID 403 with the barcode reader or RF ID reader and based on the association table or database identified, the dealing shoe 200 and the card disposal apparatus 350 read the code 201 from each card and the rank of the card is identified based on that code 102.
The above is a description of the embodiments of the present invention. Of course, various modifications, additions and alterations may be made to the embodiments described above by those skilled in the art within the scope of the present invention. For example, any fraud in games other than baccarat may be detected with the present invention. The apparatus of the present embodiments may be modified as appropriate depending on the requirements of the game to which the apparatus is to be applied.
