Patent Application
20150069700
The present disclosure relates to sorting and recovering cards and, in particular, to an apparatus, computer-readable medium, and method for sorting and recovering unused playing cards in casino games.
Each day, the gaming industry uses an untold number of playing cards. Decks of cards are typically distributed to gaming tables and used for a limited amount of time (e.g., a few hours, a day, etc.). After that amount of time, the cards are collected. To monitor possible fraud and cheating, the collected cards may be counted to determine whether any cards have been added or removed from the distributed decks. Additionally, the collected cards may be marked or destroyed to prevent use in a future live game.
In some casinos, gaming tables may be assigned as many as fifty (50) decks of cards depending on the needs of each game. By using a large number of decks, casinos can maintain a high quality and integrity level of the cards at each table. Specifically, because each card is likely to be used only once, the risk of card tampering is reduced and casino clients are assured that the cards they are handling are new. The decks of cards are shuffled together and placed in a prepared stack for each game. At the end of each day, the decks are collected and marked as used or destroyed. Due to the large number of decks that are assigned to each gaming table, many cards in those decks may remain unused. Nevertheless, those unused cards are collected along with the used cards and marked or destroyed at the end of each day.
Cards that are marked are redistributed or repurposed (e.g., made available for charity giveaways, resale as souvenirs, etc.). U.S. Pat. No. 7,959,153, incorporated herein by reference, discloses an apparatus for automatic cancellation and sorting of used or new playing cards by collecting cards following use in a casino game, marking the cards so that they cannot be reused in a casino game, and sorting the cards into decks for sale or distribution to the public. As disclosed in that patent, marking may be accomplished by using a card cancelling device such as a punch die, a cutting device, or other device for permanently including a mark indicative of cancellation on a card. But, even when cards are marked for redistribution, the cost of marking each card is significant and the original value of each card is never recovered. As a result, unused cards represent a substantial loss for casinos each year.
U.S. Pat. No. 6,250,632 discloses an automatic card sorter designed to shuffle cards for reuse or to sort the cards into decks for redistribution. Nevertheless, as disclosed in U.S. Pat. No. 7,959,153, the apparatus has several disadvantages, including: (i) the use of a large number of trays (specifically, fifty-two (52)), which adds to the size and complexity of the apparatus; and (ii) the need to move each of the trays into position, one at a time, to receive cards, which results in a sorting process that is relatively inefficient for many types of sortings. Moreover, the apparatus disclosed in the '632 patent is not capable of inspecting and verifying the condition of a card such as determining whether the card has a flaw (e.g., a marking, an indent, a cut, a hole, graffiti, etc.) that may allow someone to gain advantage during a game.
In addition, some casinos use different types of cards for different games. For example, cards with different designs may be used at the blackjack tables and the baccarat tables. Intermixing decks of different types of cards can cause confusion and provide some players with an unfair advantage. Accordingly, casinos often sort cards of each type separately. However, the effort and expense of keeping track of cards of each type is significant. As disclosed in the '153 patent, header cards can be used to separate decks into groups (e.g., decks that originate from different gaming tables). The header cards include barcodes or other markings for identification. Nevertheless, problems arise when a card of a first type is accidentally or intentionally introduced into a stack of cards of another type. Locating the dissimilar card in that stack of cards is a costly and labor-intensive process; therefore, the entire stack of cards may be destroyed to prevent potential confusion and manipulation.
Thus, from an efficiency and cost standpoint, there exists a need for a more robust manner of sorting and recovering cards, especially cards that have been designated for disposal after having not been used after a day at the casino.
According to an embodiment of the present invention, an apparatus for automatically sorting and recovering cards includes a card input device configured to receive a plurality of cards; a card sensing device configured to obtain data associated with each of the plurality of cards; and a card sorting device configured to distribute a card to one of a plurality of pockets according to a predetermined scheme to form a complete set, each of the plurality of pockets configured to hold one or more cards of the plurality of cards. The apparatus also includes a controller configured to, for each of the plurality of cards: (i) determine an identity of the card based on the data associated with the card; (ii) determine whether at least one pocket of the plurality of pockets is missing the card from the complete set based on the identity of the card; (iii) instruct the card sorting device to distribute the card to a pocket of the at least one pocket of the plurality of pockets that is missing the card in response to determining that the at least one pocket of the plurality of pockets is missing the card from a complete set; and (iv) instruct the card sorting device to distribute the card to a holding device in response to determining that the at least one pocket of the plurality of pockets is not missing the card from the complete set, the holding device configured to hold the card. The apparatus also includes a resetting device configured to, when a specific pocket holds a plurality of distributed cards comprising the complete set, reset the specific pocket. The apparatus also includes a transport device configured to transport the plurality of cards from the card input device to the card sensing device and the card sorting device.
According to another embodiment of the present invention, a non-transitory, computer-readable medium is configured to store computer-readable instructions that, when executed by a computer, instruct the computer to perform a method for automatically sorting and recovering cards. The method includes, for each of a plurality of cards, obtaining data associated with the card; determining an identity of the card based on the data associated with the card; determining whether at least one pocket of a plurality of pockets is missing the card from a complete set according to a predetermined scheme based on the identity of the card, each of the plurality of pockets configured to hold one or more cards of the plurality of cards; distributing the card to a pocket of the at least one pocket of the plurality of pockets that is missing the card from the complete set based on a predetermined scheme in response to determining that the at least one pocket of the plurality of pockets is missing the card; and distributing the card to a holding device in response to determining that the at least one pocket of the plurality of pockets is not missing the card from the complete set, the holding device configured to hold the card. The computer-readable instructions further include an instruction that when a specific pocket holds a plurality of distributed cards comprising a complete set, resetting the specific pocket.
According to yet another embodiment of the present invention, a method for automatically sorting and recovering cards includes receiving a plurality of cards. The method also includes, for each of the plurality of cards, obtaining data associated with the card via a card sensing device; determining an identity of the card based on the data associated with the card; determining whether at least one pocket of a plurality of pockets is missing the card from a complete set according to a predetermined scheme based on the identity of the card, each of the plurality of pockets configured to hold one or more cards of the plurality of cards; distributing the card to a pocket of the at least one pocket of the plurality of pockets that is missing the card from the complete set in response to determining that the at least one pocket of the plurality of pockets is missing the card; and distributing the card to a holding device in response to determining that the at least one pocket of the plurality of pockets is not missing the card from a complete set, the holding device configured to hold the card. The method also includes, when specific a pocket holds a plurality of distributed cards comprising a complete deck, resetting the specific pocket.
Other objects, features, and advantages will be apparent to persons of ordinary skill in the art from the following detailed description and the accompanying drawings.
For a more complete understanding of the present invention, needs satisfied thereby, and the objects, features, and advantages thereof, reference now is made to the following description taken in connection with the accompanying drawings.
Embodiments of the present invention, and their features and advantages, may be understood by referring to
In the gaming industry, many decks of cards are used each day. For example, a gaming table may be assigned fifty (50) decks of cards before the opening of a game session. The cards in the decks are pre-shuffled and placed in a dealer shoe at the gaming table. Cards are then removed from the shoe according to the needs of the game and used only once. At the end of the day or shift, the used cards and any remaining cards in the shoe are collected. To prevent fraud and cheating, cards, even those that have not been used at all, may be securely destroyed or marked to make sure that they cannot be reused in a live game session. For casinos, the cost of destroying unused cards can total as much as $20 million per year.
Exemplary embodiments of the present invention provide an apparatus, computer-readable medium, and method for automatically sorting and recovering cards, such as, for example, playing cards that are used in the gaming industry. Such embodiments are capable of sorting assigned but unused cards and recovering complete decks of cards. A system, for example, a banknote processing system, such as the BPS M5 offered by Giesecke & Devrient, GmbH, may be equipped with the necessary tools and instructions to read, verify, and sort cards. Specifically, the BPS M5 may be adapted and reprogrammed to identify the denomination of playing cards (e.g., suit and/or rank), sort the playing cards into decks, and band or wrap the decks. Playing cards that are placed in a feeder attached to the BPS M5 are singled, and an image sensor on the BPS M5 discriminates the suit and rank of each playing card. The BPS M5 then distributes the playing cards to one or more stackers. Once a stacker collects a complete deck, the deck is banded. Any remaining cards are subsequently destroyed by an online shredder or stacked separately for offline destruction.
Referring now to
One or more of feeder 104, sensing device 106, flaw detecting device 108, authentication device 110, card disposing device 112, card classifier 114, card sorting device 116, card holding device 118, output pockets 120, report generating device 122, report sending device 123, card banding device 124, and resetting device 125 are linked by transport mechanisms such as belts, pneumatic conveyors, or other conveying mechanisms capable of transporting sheet-like materials such as cards for automatically transporting cards between or within the devices. These transport mechanisms are individually or collectively represented by a transport device 105. The transport paths between each device are preferably as short and straight as possible to minimize the possibility of jamming or misfeeding. Open areas may be included in the card paths to provide access to cards and to permit imaging of both sides of a card.
In addition, one or more of feeder 104, sensing device 106, flaw detecting device 108, authentication device 110, card disposing device 112, card classifier 114, card sorting device 116, card holding device 118, output pockets 120, report generating device 122, report sending device 123, card banding device 124, resetting device 125, and transport device 105 are included within at least one housing (not depicted) having a display and an input device for inputting data or commands. The housing is preferably a freestanding portable housing on casters, wheels, or the like to allow movement within the card processing room. Portions of the housing may be removed or adjusted to facilitate access to cards and/or devices within card recovering apparatus 100, for example, for cleaning, repairing, replacing, or removing purposes.
Moreover, card recovering apparatus 100 comprises a controller 101. Controller 101 may represent one or more controllers, such as a central controller and/or individual device controllers. Controller 101 can be located either within card recovering device 100 or an external controller that is connected to card recovering apparatus 100 via a wired or wireless interface. Controller 101 is configured to control one or more of feeder 104, sensing device 106, flaw detecting device 108, authentication device 110, card disposing device 112, card classifier 114, card sorting device 116, card holding device 118, output pockets 120, report generating device 122, report sending device 123, card banding device 124, resetting device 125, and transport device 105 according to, for example, the flowcharts of
Cards are input into card recovering apparatus 100 via a card input device. Feeder 104 is an example of the card input device. Feeder 104 is capable of receiving a plurality of cards, and includes one or more receptacles such as bins, hoppers, or other compartments for inputting cards. Each receptacle is appropriately shaped to receive one or more cards. Specifically, each receptacle may be sufficiently large to receive multiple decks of cards. Cards can be, for example, stacked one on top of another in a receptacle. After being placed in the one or more receptacles, a plurality of cards is separated by feeder 104 and transported by transport device 105 to sensing device 106.
As the plurality of cards is fed through sensing device 106, sensing device 106 obtains data associated with each card of the plurality of cards. Sensing device 106 includes one or more of a camera, a barcode reader, a scanner, or other imaging device. Suitable imaging devices can be adapted from currency or ticket readers. Sensing device 106 captures or retrieves an image of or data regarding each card or portions of each card. In one example, sensing device 106 includes a camera to take a picture of one or both sides of each card. In another example, sensing device 106 includes a barcode reader to read serial numbers or barcodes printed on each card. The serial number or barcode printed on a card provides information (e.g., denomination information, group or classification information, etc.) about that card. In yet another example, sensing device 106 is configured to retrieve information about each card from an information resource (e.g., a local or remote server, network, or other device). Specifically, in such cases, sensing device 106 interfaces with the information resource and locate information stored about the card.
The images and/or data obtained by sensing device 106 may be used for card identification, counting, grading, verification, and classification. Card counting is useful for security purposes in order to alert a casino or other gaming establishment of missing cards that could be used fraudulently. Upon being alerted, a casino will have time to take preventive measures (e.g., change to new cards, set up monitoring, etc.) to reduce the risk of cheating. Card grading is useful to determine whether cards have been damaged and thus are unsuitable for recovering and reuse.
In addition to sensing device 106 or other sensing devices that permit identification, verification, and/or inspection of cards, card recovering apparatus 100 may include sensors for carrying out functions such as card routing, identifying misfeeds (e.g., double or multi-card feeds, skewed feeds, etc.) or jams, and so forth, as is well-known in the art of document or sheet feeding. For example, such sensors include barcode readers, scanners, or other imaging devices capable of reading the barcodes on header cards that separate decks into different groups. These sensors may be associated with or independent of sensing device 106.
Sensing device 106 is connected to one or more of controller 101, flaw detecting device 108, authentication device 110, card classifier 114, card sorting device 116, and card holding device 118. Controller 101, operating as identity determining device 101A (as depicted in
In addition, flaw detecting device 108 uses the images and/or data obtained by sensing device 106 to determine whether any cards of the plurality of cards comprise a flaw or a sign of usage (e.g., a marking, an indent, a cut, a hole, ink or surface wear, bending, etc.) and are thus unsuitable for sorting and recovering. For example, flaw detecting device 106 compares the images and/or data obtained for each card with a stored reference (e.g., an image of the card having no flaws) and determines whether any variations exist between the obtained images and/or data and the stored reference. Moreover, authentication device 110 uses the images and/or data obtained by sensing device 106 to determine whether each card of the plurality of cards comprises a particular authenticity feature (e.g., a unique serial number or barcode, a watermark, a hologram, a security thread, optically variable ink, a chip, microtext, a pattern, or other marking).
Furthermore, card classifier 114 uses the images and/or data obtained by sensing device 106 to identify a characteristic marking on each card (e.g., a design, a pattern, or other marking) or a shape of each card. Controller 101, operating as pocket assignment determining device 101B (as depicted in
Flaw detecting device 108, authentication device 110, and card classifier 114 may be associated with or independent of controller 101. In certain embodiments of the invention, controller 101 operates as one or more of flaw detecting device 108, authentication device 110, and card classifier 114.
In such a configuration, when flaw detecting device 108 determines that a card of the plurality of cards has a flaw or a sign of usage, that card is sent to card disposing device 112, examples of which include a conventional shredder, an incinerator, or other device that is capable of disposing of or destroying cards. Controller 101, operating as instructing device 101C (as depicted in
Cards that are authenticated (e.g., determined to have a particular authenticity feature) and are otherwise suitable for sorting and recovering (e.g., determined to not have any flaws or signs of usage) are distributed to an individual output pocket 120. Specifically, for each of the cards, controller 101, operating as pocket assignment determining device 101B (as depicted in
When controller 101 determines that none of output pockets 120 are missing a card, that card is sent to a card holding device 118. Suitable card holding devices include any device capable of receiving, holding, and dispensing cards under the instruction of a controller (e.g., controller 101). An example of card holding device 118 is an additional output pocket that is capable of receiving and holding cards. Another example of card holding device 118 is using spools of the type presently used in currency recycling machines, although adapted (e.g., shaped accordingly) to hold cards. Controller 101, operating as instructing device 101C (as depicted in
When a specific output pocket 120 holds a plurality of distributed cards that forms a complete deck, card banding device 124 bands or wraps the plurality of distributed cards. A pocket monitoring device monitors output pockets 120 to determine when a specific output pocket 120 holds a complete deck of cards. In certain embodiments of the invention, controller 101 is configured to operate as the pocket monitoring device. As an example, in
Banding involves, for example, using a section of material to bind, tape, or otherwise hold together one or more cards. In one example, a strip of is used to hold the plurality of distributed cards together. A labeling device (e.g., a label printer) is used to label the strip of paper with information such as the pocket that the cards came from, a date and time (e.g., the date and time that the banding was completed), the type of card or group associated with the card, etc. Additionally, resetting device 125 resets the specific output pocket 120 to receive a new deck of cards. Specifically, resetting device 125 indicates that the specific output pocket 120 is ready to receive a new deck of cards by clearing information stored about the specific output pocket 120. Resetting device 125 is either associated with or independent of controller 101. In certain embodiments of the invention, controller 101 is configured to operate as resetting device 125.
After card recovering apparatus 100 has sorted, recovered, and/or disposed of each of the plurality of cards placed in feeder 104, report generating device 122 generates a sorting report. The sorting report can include a list of disposed cards (in other words, cards of the plurality of cards that were disposed by card disposing device 112). In addition, the sorting report can include a list of cards that a pocket 120 is still missing. A counting device determines whether a pocket 120 is still missing a card. When a pocket is still missing a card, a missing card identifying device determines an identity of the missing card. The counting device and the missing card identifying device may be associated with or independent of controller 101. In certain embodiments of the invention, controller 101 operates as the counting device and/or the missing card identifying device. As an example, in
Report sending device 123 then sends the sorting report to an administrator (e.g., management or security). Specifically, report sending device 123 sends a message containing the sorting report to the administrator. Upon receiving the sorting report, the administrator is able to take necessary steps to recover or obtain any cards that are still missing or needed.
In addition to sorting decks of cards, card recovering apparatus 100 may also be adapted to process header cards for separating decks into different groups, for example, decks originating from different gaming tables. In such cases, card recovering apparatus 100 obtains information about cards that are being sorted and recovered from the header cards. For example, in situations when only partial decks of cards are being collected for sorting/recovering (for example, when only the unused cards in a shoe are collected), header cards may be used track the number of cards that were removed from the decks (for example, in the case involving unused cards in a shoe, this number would represent the number of cards that were used) and provide that information to card recovering apparatus 100. Such information would facilitate future efforts to balance the number of cards that are assigned/distributed to different gaming tables. Header cards processed by card recovering apparatus 100 are separated from the other cards by controller 101. Specifically, as noted above, controller 101 is capable of separating cards into different groups based on their characteristic markings. Thus, in such a case, controller 101 identifies each header card based on its characteristic markings and sorts it into a separate pocket 120. The number and arrangement of pockets 120 are modified as necessary to accommodate header cards and/or different groups of cards.
Card recovering apparatus 100 may also be adapted for use in a secure card room of a casino. In such cases, a card recovering apparatus is configured to identify, verify, sort, and/or recover incoming and outgoing decks of cards. New cards are placed in feeder 104, and card recovering apparatus 100 processes them to an output pocket 120. Card recovering apparatus 100 is programmed to identify all types of cards including material (e.g., paper, plastic, etc.), design, and color makeup. The apparatus preferably stores the results of any completed sorting to provide an electronic trail of the sorting and/or prints the result to provide a paper trail. The results of a sorting can include, for example, a list of cards that were disposed of during the sorting process, a list of missing cards in any output pocket 120 at the completion of the sorting, and/or a total number of decks recovered by the sorting.
In certain embodiments of the invention, multiple recovery cycles are possible. For example, a single card may be recovered more than one time by card recovering apparatus 100. As noted above, card recovering apparatus is capable of sorting and recovering cards that remain unused after a first shift at a casino. Note that cards that have been used can also be recovered by card recovering apparatus 100. Recovered cards can be redistributed to a gaming table during a second shift at the casino. Cards that remain unused during the second shift may again be sorted and recovered by card recovering apparatus, and so on and so forth. In cases involving multiple recovery, a robust fitness detection process must be employed to ensure that recovered cards are free from flaws and/or any signs of usage (e.g., ink wear, surface wear, color changes, etc.).
In some embodiments of the invention, sets of cards (e.g., complete decks of cards, incomplete decks of cards) that are recovered by card recovering apparatus 100 are disposed of and/or destroyed by card disposing device 112 in order to establish a balance between the number of recovered cards and new cards used during a shift or table game session at a casino. Incomplete decks of cards that are recovered by card recovering apparatus 100 can be disposed of and/or destroyed to maintain a consistent number of each card.
In particular embodiments of the invention, card recovering apparatus 100 may not include one or more of flaw detecting device 108, authentication device 110, card classifier 114, card holding device 118, report generating device 122, report sending device 123, and resetting device 125.
Referring to
In S301, feeder 104 receives the plurality of cards. In S303, feeder 104 separates a first card from the plurality of cards, and transport device 105 transports the first card to sensing device 106. In S305, sensing device 106 obtains data associated with the first card. As described above, obtaining data associated with a card involves, for example, capturing an image of the card or a portion of the card. Alternatively, obtaining data associated with a card involves retrieving information about the card from an information resource (e.g., a local or remote server, network, or other device). In S307 and S309, controller 101, operating as identity determining device 101A, identifies the first card by rank and suit by analyzing (e.g., examining, inspecting, scanning, etc.) the data associated with the first card.
In S311 and S313, flaw detecting device 108 checks the first card for any flaws, signs of usage, or other items that may allow a player to gain an unfair advantage during a game. Checking the first card for a flaw or sign of usage involves, for example, analyzing the data associated with the first card that was obtained by sensing device 106 (e.g., an image of the first card) and determining whether that data reveals a flaw or a sign of usage. Cards that are found to have any flaws (S311: YES) or signs of usage (S313: YES) are sent to card disposing device 112, and the process proceeds to S345. In S345, card disposing device 112, as instructed by controller 101 operating as instructing device 101C, shreds, incinerates, or otherwise disposes of such cards.
In S315, authentication device 110 determines whether the first card possesses a predetermined authenticity feature such as, for example, a unique serial number or a specific mark for a particular casino. Determining whether the first card comprises a predetermined authenticity feature involves, for example, analyzing the data associated with the first card that was obtained by sensing device 106 (e.g., an image of the first card) and determining whether the predetermined authenticity feature is present in the data. Cards that are found to not have the predetermined authenticity feature (e.g., cards that do not have a serial number, have a duplicate serial number, or an invalid serial number) (S315: NO) are also sent to card disposing device 112.
Cards that are marked for disposal may also be manually inspected and placed back in card recovering apparatus 100 to be sorted when no flaw or sign of usage is found and/or the cards have the predetermined authenticity feature. Cards that are authenticated via a different method (e.g., determined to have a different authenticity feature) may also be placed back in card recovering apparatus 100. When flaws are confirmed during manual inspection or when a questionable card (e.g., a card lacking the predetermined authenticity feature) is identified, appropriate documents or reports can then be generated, management or security notified, and/or other steps taken as necessary.
Those of ordinary skill in the art will appreciate that S311 (checking for flaws), S313 (checking for signs of usage), and S315 (checking for a predetermined authenticity feature) are performed in any order or concurrently. Moreover, S311, S313, and S315 are performed before, during, or after card identification (S307 and S309), either as a part of the card identification process or as a separate process.
Continuing now to S317, S319, and S321, when the first card is suitable for sorting and recovering (in other words, can be authenticated and does not have any flaws or signs of usage), transport device 105 transports the first card to the card sorting device 116. Then, controller 101, operating with card sorting device 116, performs a first round of sorting. Specifically, a counter nC is used to track the sorting. At the start of the first round of sorting, the counter nC is set to one (1) to signify the start of the first round of sorting. In S319, controller 101, operating as pocket assignment determining device 101B, determines whether a first output pocket 120 is missing the first card (e.g., needs the first card to complete a deck). In
The process of determining whether an output pocket 120 is missing the first card may be repeated until controller 101 checks each and every output pocket 120 of card recovering apparatus 100. For example, when additional output pockets 120 (e.g., a pocket C, a pocket D, etc.) exist, controller 101 proceeds to a next output pocket, according to an order set by a predetermined scheme, and determine whether that output pocket is missing the first card from a complete set according to the predetermined scheme. An example of the complete set according to the predetermined scheme is a full deck of playing cards. When that output pocket is missing the first card, controller 101 instructs card sorting device 116 to distribute the first card to that output pocket. When that output pocket is not missing the first card, controller 101 proceeds to yet another output pocket, in the order set by the predetermined scheme, and determines whether that pocket is missing the first card, and so on and so forth. In the example depicted in
Continuing to S329, S330, and S331, when none of output pockets 120 are missing the first card, controller 101 determines whether counter nC exceeds a predetermined number of runs or rounds of sorting. More specifically, in S329, controller 101 determines whether a sufficient or required number of rounds of sorting have been performed. When a sufficient number of rounds have been performed (S329: YES), the process proceeds to S345 and controller 101 instructs card disposing device 112 to dispose of the first card. When a sufficient number have not been performed (S329: NO), the process proceeds to S330 and S347. In S330, counter nC is increased by one (1). Thus, when only one round of sorting has been performed, counter nC is set to two (2).
Those of ordinary skill in the art will appreciate that a system other than a count system may be used to track the sorting. Moreover, in certain embodiments, the sorting is not tracked; cards that are suitable for sorting may undergo as many rounds of sorting as necessary until they are sorted into an output pocket 120.
Referring now to S331, holding device 118, instructed by controller 101 operating as instructing device 101C, will hold the first card for a predetermined period of time. The holding device 118 may be referred to as a “reject pocket.” As described above, holding device 118 is, for example, an additional output pocket 120 that is configured to hold any rejected cards. Rejected cards include those cards that are not sorted to an output pocket 120 during a round of sorting. More specifically, rejected cards are those cards that none of output pockets 120 are missing at the time they are sorted. Holding device 118 may hold the card for a specific period of time (e.g., a number of seconds, minutes, hours, or days) or until each of the plurality of cards has undergone at least one round of sorting. After that time, holding device 118 passes the card back to card sorting device 116, and the process returns to S319. A second round of sorting then commences.
In addition, during the predetermined period of time, the process also proceeds to S347. In S347, controller 101 determines whether there are more cards in the plurality of cards (S347). When there are more cards (S347: YES), the process will proceed back to S303, and a new card of the plurality of cards will be selected. When there are no more cards (S347: NO), the process will proceed to S351.
In certain embodiments, rounds of sorting are performed without a count system. More specifically, when a card is suitable for sorting and recovering (in other words, is genuine and fit) but none of output pockets 120 is currently missing the card, the card is sent to holding device 118. After a period of time, that card and any other cards in holding device 118 are collected and placed back into feeder 104. This process may be performed manually by a user. The cards are then reexamined for authenticity and flaws, which may be preferable when a particular card is processed too many times. In such embodiments, card recovering apparatus 100 need not track of the rounds of sorting nor the predetermined period of time (in other words, S317, S329, and S331 may be omitted).
Controller 101, operating as pocket monitoring device 101D, also checks to see whether an output pocket 120 holds a plurality of distributed cards that comprise a complete deck. Such monitoring can be performed each time a card of the plurality of cards is distributed to an output pocket 120 (in other words, following S337). Alternatively, controller 101 periodically checks output pockets 120 to determine whether any hold a plurality of distributed cards comprising a complete deck. When controller 101 determines that a specific output pocket 120 holds a plurality of distributed cards that comprise a complete deck (S337: YES), banding device 124 bands the plurality of distributed cards in that specific output pocket 120 (S339). The banded plurality of distributed cards then is removed from the specific output pocket 120 (S341), and the specific output pocket 120 is reset by resetting device 125 (S343). In certain embodiments of the invention, S341 is omitted. Thus, in such configurations, the banded plurality of distributed cards continue to be held in the specific output pocket 120.
In embodiments of the invention, multiple decks of cards are processed at the same time. Accordingly, even if cards are missing from a single deck, several complete decks can be formed with the plurality of cards. After the plurality of cards have all been sorted (i.e., distributed to an output pocket 120, disposed of by card disposing device 112, etc.), in S351, controller 101, operating as counting device 101E, determines whether any output pocket 120 is still missing a card. In other words, controller 101 determines whether any output pocket 120 still has an incomplete deck of cards. When a specific output pocket 120 is found to have a missing card (S351: YES), controller 101, operating as missing card determining device 101F, will determine an identity of the missing card (S353). In S355, report generating device 122 then will generate a sorting report including the identity of the missing card. In S357, report sending device 123 will send the sorting report to an administrator (e.g., management or security), thereby notifying them of the missing card. Steps can then be taken to obtain the missing card and complete the deck. Alternatively, the incomplete deck of cards may be collected and destroyed or treated as rejected cards and reprocessed with the next batch of cards.
In certain embodiments, when more than one output pocket 120 has an incomplete deck of cards, controller 101 determines whether the incomplete decks may be resorted to form one or more complete decks of cards. Such a situation may arise when a particular card is distributed to a later output pocket 120 because an earlier output pocket 120 already has the particular card at the time it is sorted. However, once the cards in that earlier output pocket 120 are banded, that output pocket 120 may collect new cards but, at the end, still require the particular card to form a complete deck. When controller 101 determines that the incomplete decks comprise one or more complete decks, card recovering apparatus 100 resorts the incomplete decks to recover those complete decks.
Returning to S351, when none of output pockets 120 is missing a card (S351: NO), the process terminates.
In certain embodiments of the invention, more than one card of the plurality of cards is selected and sorted at the same time (e.g., in S303, more than one card may be selected). Moreover, in certain embodiments, one or more of S311 (checking for flaws), S313 (checking for signs of usage), and S315 (checking for a predetermined authenticity feature) is omitted. In addition, in certain embodiments, S317, S329, S330, and S331 may be omitted. Accordingly, in such embodiments, only one round of sorting may be performed. Further, in certain embodiments, S351, S353, S355, and S357 are omitted. Accordingly, in such configurations, the process terminates when controller 101 determines that there are no more new cards remaining in the plurality of cards (S347: NO).

Subsequently, a second card, C2, is selected from the plurality of cards. Controller 101 determines that C2 is a four of spades; thus, the identity of C2 is represented as “1-4.” Controller 101 then determines that pocket A is also missing C2. Accordingly, controller 101 also assigns C2 to pocket A.
The above process is repeated with the rest of the cards, C3-C10. C3-05, C7, and C9 are also assigned to pocket A. C6 is assigned to pocket B because C6 has the same identity as C1 (in order words, C6 also has a suit “spades” and a rank “two”). Similarly, C8 is also assigned to pocket B. Lastly, C10 is assigned to pocket R or, in other words, it is rejected and assigned for disposal or resorting.
Each of the plurality of cards is sorted to one of pocket A, pocket B, and pocket R according to each card's pocket assignment. Cards are stacked in one of pocket A and pocket B based on the order that they are received. Thus, in
In certain embodiments, pocket R corresponds to card holding device 118 instead of card disposing device 112. Pocket R, for example, holds cards that are assigned to it for a predetermined period of time and subsequently delivers those cards back to card sorting device 116. Controller 101, operating as pocket assignment determining device 101B, will then determine once again whether pocket A or pocket B is missing the card. Alternatively, cards that are sent to pocket R are held for a period of time and then placed back into feeder 104.
