Description
TECHNICAL FIELD

The disclosure relates to card handling devices and related assemblies, components, and methods. In particular, embodiments of the disclosure relate to card handling devices, card buffer areas of card handling devices, substantially flat card output areas of card handling devices, and methods of shuffling cards.


BACKGROUND

Wagering games are often based on the outcome of randomly generated arrangements of cards. Such games are widely played in gaming establishments and, often, a single deck or multiple decks of fifty-two (52) playing cards may be used to play the game. Gaming using multiple decks of playing cards may include, for example, six to ten decks used in games such as blackjack and baccarat and two decks of playing cards used in games such as double deck blackjack. Many other specialty games may use single or multiple decks of cards, with or without jokers and with or without selected cards removed.


From the perspective of players, the time the dealer must spend in shuffling diminishes the excitement of the game. From the perspective of casinos, shuffling time reduces the number of hands played and specifically reduces the number of wagers placed and resolved in a given amount of time, consequently reducing casino revenue. Casinos would like to increase the amount of revenue generated by a game without changing the game or adding more tables. One option to increase revenue is to decrease the time the dealer spends handling and shuffling playing cards. This may be accomplished by using one set of cards to administer the game while shuffling a second set of cards. Other options include decreasing shuffling time.


The desire to decrease shuffling time has led to the development of mechanical and electromechanical card shuffling devices. Such devices increase the speed of shuffling and dealing, thereby increasing actual playing time. Such devices also add to the excitement of a game by reducing the amount of time the dealer or house has to spend in preparing to play the game.


However, working with many existing shuffler designs puts unnecessary strain on the muscles of the users (dealers). Using two complete sets of cards also increases the cost of offering the game.


Furthermore, the card output area or shoe used in conjunction with shufflers often places strain on dealers' hands and wrists by using card distribution interfaces to output cards that are oriented at a substantial acute angle relative to the table surface. To draw cards from these shoes, dealers often have to twist their wrists repeatedly at awkward and uncomfortable angles. Moreover, shoes often are not easily adjustable to meet a dealer's card drawing preference (e.g., direction in which dealers prefer to draw a card relative to the table).


Card counting is a significant problem when using automatic card shufflers. Casinos often lose a house advantage when players are able to predict what cards remain to be dealt and the proximity of those cards being dealt. It is desirable for casinos to reduce or eliminate the ability for players to count cards. Continuous shuffling machines assist in reducing the ability to count cards, but additional ways to eliminate card counting and improve ergonomics of card delivery may be desirable.


BRIEF SUMMARY

Some embodiments of the present disclosure include a card handling device having a card shuffling apparatus for shuffling playing cards and a card output portion. The card output portion may include a card buffer area positioned at an interface of the card shuffling apparatus and the card output portion.

DETAILED DESCRIPTION

As used herein, any relational term, such as “first,” “second,” “over,” “beneath,” “top,” “bottom,” “underlying,” “up,” “down,” etc., is used for clarity and convenience in understanding the disclosure and accompanying drawings, and does not connote or depend on any specific preference, orientation, or order, except where the context clearly indicates otherwise. For example, these terms may refer to an orientation of elements of the card handling device relative to a surface of a table on which the card handling device may be positioned, mounted, and/or operated (e.g., as illustrated in the figures).


As used herein, the terms “vertical” and “horizontal” may refer to a drawing figure as oriented on the drawing sheet, and are in no way limiting of orientation of an apparatus, or any portion thereof, unless it is apparent that a particular orientation of the apparatus is necessary or desirable for operation in view of gravitational forces. For example, when referring to elements illustrated in the figures, the terms “vertical” or “horizontal” may refer to an orientation of elements of the card handling device relative to a table surface of a table to which the card handling device may be mounted and operated.


Some embodiments of the present disclosure may include card handling devices having “card buffer areas” (e.g., area within the card handling device where playing cards can be temporarily collected). The card handling devices may include a card buffer area that moves relative to a card shuffling apparatus as playing cards are inserted into the card buffer area. As a card buffer area moves, the card shuffling apparatus may insert playing cards at both a top and a bottom of (e.g., beneath) a group of playing cards that is already present in the card buffer area. Some embodiments of the present disclosure may include card handling devices that have playing cards overtake the group of playing cards in the card buffer area. In other words, cards may pass up other cards in the card buffer area such that the cards passing up the other cards are drawn (e.g. dealt) from the card handling device prior to the other cards in the card buffer area. Put another way, playing cards already in the card buffer area may have an order in which the playing cards are going to be dealt from the card handling device, and the card handling device may enable other playing cards to bypass (e.g., jump ahead of in order) the playing cards already in the card buffer area and be dealt prior to the playing cards already in the card buffer area. For example, the card buffer area may have playing cards drawn (to be dealt) from a top a group of playing cards within the card buffer area, and the card buffer area may enable one or more cards to be positioned on top of a stack of cards in the card buffer area (e.g., so that the one or more cards will be drawn before the remaining cards in the card buffer area) or in another position in the stack of cards (e.g., the bottom of the stack).


Some embodiments of the present disclosure may include card handling devices that include a substantially flat card output area (e.g., a substantially flat card delivery area or substantially flat card shoe). The substantially flat card output area may include an interface portion having a surface that is oriented at relatively small acute angles (e.g., 5° to 20°) relative to a table surface of a table to which the card handling device may be positioned and/or mounted. The substantially flat card output area may further allow playing cards to be drawn from an outlet of the substantially flat card output area throughout a range of at least substantially horizontal directions, including directions that are perpendicular to each other.


A perspective view of a card handling device 100, according to an embodiment of the present disclosure, having portions of one or more housings of the card handling device 100 removed to show interior components of the card handling device 100, is shown in FIG. 1. The card handling device 100 may be configured to be mounted with at least a majority of the card handling device 100 beneath a level of a table surface (e.g., a gaming table surface) of a table (e.g., a gaming table) and to deliver shuffled playing cards to the table surface and/or receive playing cards to be shuffled from or proximate the table surface. The card handling device 100 may include a frame structure 102, a housing 104, a control system 105 in communication with a display 106, and a substantially flat card output area 108, relative to the table surface.



FIG. 2 shows a side elevation view of the card handling device 100 of FIG. 1 with additional portions of the one or more housings of the card handling device 100 removed to show interior components of the card handling device 100. The card handling device 100 may include a card input portion 202, a card shuffling apparatus 204, and a card output portion 206. The card input portion 202 may include a card intake area 208 for receiving playing cards to be shuffled. The card intake area 208 may be arranged on a same side of the card shuffling apparatus 204 of the card handling device 100 as the substantially flat card output area 108. Furthermore, the card intake area 208 may be oriented to be positioned above and proximate to, such as resting upon, a table surface 210 when the card handling device 100 is mounted to a table 212 and may be accessible to a dealer administering a game at the table 212 to which the card handling device 100 is mounted. As a result, when the card handling device 100 is mounted to a table 212, the substantially flat card output area 108 and card intake area 208 may be oriented proximate in location to each other and to the top surface 210 of the table 212. The orientation of the card intake area 208 of the card input portion 202 and the substantially flat card output area 108 may reduce an amount of the card handling device 100 that needs to be exposed above a table surface 210 of the table 212 to which the card handling device 100 is mounted. The card output portion 206 may include a card buffer area 214 proximate an interface 216 of the card output portion 206 and the card shuffling apparatus 204 of the card handling device 100.


In operation, the card input portion 202 may receive unshuffled playing cards from a table 212 at the card intake area 208 and may deliver the unshuffled playing cards to the card shuffling apparatus 204. The card shuffling apparatus 204 may at least partially shuffle the unshuffled playing cards and may deliver shuffled playing cards to the card buffer area 214 of the card output portion 206 of the card handling device 100. The card output portion 206 may transport playing cards from the card buffer area 214 (e.g., one-at-a-time) to the substantially flat card output area 108 where a dealer may manually draw the playing cards (e.g., one-at-a-time) from the substantially flat card output area 108 for the distribution of cards.


An enlarged side view of the card input portion 202 of the card handling device 100 as shown in FIG. 2 is shown in FIG. 3. The card input portion 202 may include a first frame assembly 302, a first pivoting axis 304, a first card feed system 306, a first card imaging system 308, and a first sensor 310. The first card feed system 306 may include a first card pathway 312 (e.g., pathway along which playing cards move through the card input portion 202). The first card pathway 312 may lead from the card intake area 208 of the card input portion 202 to the card shuffling apparatus 204 of the card handling device 100. The first card feed system 306 may further have a set of pick-off rollers 314 that transport playing cards individually in a direction indicated by arrow 315. Additional pairs of rollers 316, 318a, 318b, 320a, and 320b may displace playing cards from the card intake area 208 to the card shuffling apparatus 204. For example, a stack of unshuffled playing cards may be placed in the card intake area 208, and the set of pick-off rollers 314 of the first card feed system 306 may take playing cards individually from a bottom of (e.g., beneath) the stack of unshuffled playing cards and the additional pairs of rollers 316, 318a, 318b, 320a, 320b may transport the playing cards to the card shuffling apparatus 204. In some embodiments, the card intake area 208 may be configured to receive one or more playing cards. In some embodiments, the card intake area 208 may be configured to receive one or more decks of playing cards at a time.


In some embodiments, the first card imaging system 308 may be oriented along the first card pathway 312 of the first card feed system 306. The first card feed system 306 may transport playing cards past the first card imaging system 308, and the first card imaging system 308 may capture identifying information of each playing card as each playing card moves along the first card pathway 312 before insertion into the card shuffling apparatus 204. For example, the first card imaging system 308 may include a camera or line scanning device that captures an image of each card. In some embodiments, the first card imaging system 308 may comprise one or more of the imaging devices described in U.S. Pat. No. 7,933,448 to Downs, issued Apr. 26, 2011, in U.S. Pat. No. 7,764,836 to Downs et al., issued Jul. 27, 2010, or in U.S. Pat. No. 8,800,993 B2 to Blaha et al., issued Aug. 12, 2014, the disclosure of each of which is incorporated herein in its entirety by this reference. In some embodiments, the first card imaging system 308 may not need to capture an image of an entire card, but may detect only rank and suit information, special markings on the playing cards, such as, for example, a lot number, a casino identifier, a shoe number, a shift number, a table number, bar code, glyph, any other known type of special marking, or combinations thereof. In some embodiments, the control system 105 (FIG. 1) of the card handling device 100 may receive signals from the first card imaging system 308 to determine rank and/or suit of each playing card being read or sensed by the first card imaging system 308. The control system 105 (FIG. 1) of the card handling device 100 may store at least some data related to each playing card (e.g., an inventory of the playing cards handled by the card handling device 100, a complete card set composition, etc.) in a memory portion of the control system 105 (FIG. 1). Stored data may be compared to data collected at the first card imaging system 308 or another location in the card handling device 100. For example, the first card imaging system 308 may be used in conjunction with a second card imaging system 508 (FIG. 5A) in the card output portion 206 to keep an inventory of the playing cards maintained in the card shuffling apparatus 204, fed from the card intake area 208 to the card shuffling apparatus 204, and fed from the card shuffling apparatus 204 to the substantially flat card output area 108. In other words, a total inventory of the cards sent through the card handling device 100 may be maintained. Interaction of the first and second card imaging systems 308, 508 is described in further detail in regard to FIG. 5A.


The first sensor 310 of the card input portion 202 may be oriented proximate the card intake area 208 and may be used to sense whether playing cards are present in the card intake area 208. Furthermore, the first sensor 310 may be configured to send signals to and inform the control system 105 (FIG. 1) that playing cards are present in the card intake area 208. Furthermore, the control system 105 (FIG. 1) may be configured to initiate a shuffling cycle (e.g., process of shuffling playing cards with the card handling device 100) when playing cards are placed in the card intake area 208 and sensed by the first sensor 310. In some embodiments, the first sensor 310 may include at least one of an optical sensor and an infrared sensor.


Referring to FIGS. 2 and 3 together, the first pivoting axis 304 of the card input portion 202 may comprise a first shaft 322 rotatably mounted at both ends to the frame structure 102 of the card handling device 100. The first shaft 322 of the first pivoting axis 304 may extend axially along a horizontal plane that is substantially parallel to a table surface 210 of a table 212 to which the card handling device 100 may be mounted. Furthermore, the first pivoting axis 304 of the card input portion 202 may be oriented proximate the card intake area 208 of the card input portion 202 and may be positioned and spaced above a table surface 210 of a table 212 when the card handling device 100 is mounted to a table 212. In some embodiments, the card input portion 202 may be rotatable about the first pivoting axis 304 in a direction represented by arrow 305 relative to the remainder of the card handling device 100. The card input portion 202 may be rotatable away from the card output portion 206 in direction 305 and card shuffling apparatus 204 of the card handling device 100, and the card output portion 206 and card shuffling apparatus 204 may be at least partially exposed when the card input portion 202 is rotated away from the card output portion 206 and card shuffling apparatus 204. For example, during use, the card input portion 202 may be rotated about the first pivoting axis 304 and away from the card output portion 206 and card shuffling apparatus 204 of the card handling device 100 in order to facilitate maintenance, troubleshooting, and/or repair of the card handling device 100. In other words, in FIG. 3, the card input portion 202 may be rotated about the first pivoting axis 304 to expose other portions of the card handling device 100 for maintenance.


A cross-sectional side view of the card shuffling apparatus 204 of the card handling device 100 of FIG. 1 is shown in FIG. 4A. As shown in FIG. 4A, the card shuffling apparatus 204 may include a multi-compartment carousel 402 and a packer arm device 404. The multi-compartment carousel 402 of the card shuffling apparatus 204 may have a plurality of compartments 406 (e.g., thirty-nine compartments 406) formed between spaced pairs of adjacent fingers 408, 410 extending from a rotatable center member 412. Each compartment 406 of the plurality of compartments 406 may be defined between two spaced pairs of adjacent fingers 408, 410 of the multi-compartment carousel 402. The fingers 408, 410 may each include a beveled edge 414, 416 that enables and guides insertion of playing cards on top of or below playing cards previously deposited in the plurality of compartments 406 by the first card feed system 306 (FIG. 3) of the card input portion 202. The beveled edges 414, 416 may include flat, angled surfaces or curved surfaces. Card edges of playing cards may contact the beveled edges 414, 416 and may be deflected and guided into the compartments 406. In some embodiments, the adjacent fingers 408, 410 may include a biased element (e.g., spring 418) extending between the adjacent fingers 408, 410 for assisting in holding playing cards securely within the plurality of compartments 406 after insertion into the multi-compartment carousel 402. It is noted that in other embodiments, the multi-compartment carousel 402 may include fewer than thirty-nine (39) compartments 406 or more than thirty-nine (39) compartments 406. In some embodiments, each compartment 406 of the plurality of compartments 406 may be sized and shaped to hold between six and twenty playing cards. In some embodiments, each compartment 406 of the plurality of compartments 406 may be sized and shaped to hold between ten and sixteen playing cards. For example, each compartment 406 of the plurality of compartments 406 may be sized and shaped to hold thirteen cards.


Although, the card handling device 100 of the present disclosure is described as the card shuffling apparatus 204 including a multi-compartment carousel 402, the card shuffling apparatus 204 may include any suitable shuffling mechanism such as, for example, those disclosed in U.S. Pat. No. 5,676,372 to Sines et al. that issued Oct. 14, 1997, U.S. Pat. No. 6,254,096 to Grauzer et al. that issued Jul. 3, 2001, U.S. Pat. No. 6,651,981 to Grauzer et al. that issued Nov. 25, 2003, and U.S. Pat. No. 6,659,460 to Blaha et al. that issued Dec. 9, 2003, the disclosures of each of which are incorporated herein in their entireties by this reference. In some embodiments, the card shuffling apparatus 204 may have a wheel or carousel design that may be somewhat similar to the card-shuffling devices disclosed in the aforementioned and incorporated by reference U.S. Pat. Nos. 6,659,460 and 8,800,993 B2.


In some embodiments, the card shuffling apparatus 204 may operate, in at least one operational mode, as a continuous shuffling machine. In other words, the card shuffling apparatus 204 may be configured to continuously receive cards (e.g., after each round of play) and may continuously shuffle cards and provide cards to the dealer without unloading unused cards. In contrast, batch shuffling the one or more decks of cards involves unloading the entire set of cards after each shuffling cycle. For example, the card shuffling apparatus 204 may shuffle the playing cards such that playing cards discarded and reinserted into the card handling device 100 from a previous round have a chance of appearing (e.g., being dealt) in the next round.


In some embodiments, the card shuffling apparatus 204 may operate, in at least one operational mode as a batch shuffling machine. For example, the card shuffling apparatus 204 may be configured to shuffle a complete set or “shoe” of one or more decks of cards (e.g., one, two, four, six, eight decks of cards, etc.) and then provide the cards from those decks to the dealer (e.g., one card at a time) until the set of cards is depleted, or a cut card is reached.



FIG. 4B is an enlarged perspective view of the packer arm device 404 of the card shuffling apparatus 204 of FIG. 4A. Referring to FIGS. 4A and 4B together, the packer arm device 404 of the card shuffling apparatus 204 may assist in inserting playing cards into each compartment 406 of the plurality of compartments 406 of the multi-compartment carousel 402. The packer arm device 404 may include a motor 420, an elongated packer arm 422, a packer arm shaft 423, and an eccentric cam member 424. The elongated packer arm 422 may include a pusher portion 426 and a pivot arm portion 428. The pusher portion 426 of the elongated packer arm 422 may have a generally L-shape having a first leg 430 and a second leg 432. The second leg 432 may extend from a first end of the first leg 430 in a direction at least generally perpendicular to a direction in which the first leg 430 extends. The pivot arm portion 428 of the elongated packer arm 422 may extend from a second end of the first leg 430 in a direction at least substantially opposite to the direction in which the second leg 432 of the pusher portion 426 of the elongated packer arm 422 extends. The second end of the first leg 430 may be rotatably coupled to the packer arm shaft 423, which may be connected to the frame structure 102 of the card handling device 100. The pivot arm portion 428 of the elongated packer arm 422 may be coupled to the eccentric cam member 424.


The elongated packer arm 422 may rotate about the packer arm shaft 423 and the second leg 432 of the pusher portion 426 of the elongated packer arm 422 may translate partially along the first card pathway 312 of the first card feed system 306 (FIG. 3) to ensure proper loading of the playing cards within the plurality of compartments 406 of the multi-compartment carousel 402. The motor 420 may rotate the eccentric cam member 424, which may, in turn, cause the elongated packer arm 422 of the packer arm device 404 to rock back and forth along an arc-shaped path.


In some embodiments, the packer arm device 404 may be used to provide additional force to a playing card along the first card pathway 312 as the playing card leaves the pair of rollers 320a, 320b. For example, the packer arm device 404 may be located in the card handling device 100 such that a portion of the second leg 432 of the elongated packer arm 422 of the packer arm device 404 may abut against a trailing edge of a playing card and force the playing card at least substantially completely into a compartment 406 of the plurality of compartments 406 of the card shuffling apparatus 204. In some embodiments, the packer arm device 404 may be similar to the devices disclosed in the aforementioned and incorporated by reference U.S. Pat. Nos. 6,659,460, 7,766,332, and 8,800,993 B2.


A side view of the card output portion 206 of the card handling device 100 of FIG. 1 in a first orientation is shown in FIG. 5A. An enlarged side view of the card output portion 206 in the first orientation is shown in FIG. 5B. A side view of the card output portion 206 of the card handling device 100 of FIG. 1 in a second orientation is shown in FIG. 5C. An enlarged side view of the card output portion 206 in the second orientation is shown in FIG. 5D. An enlarged perspective view of the card buffer area 214 of the card output portion 206 of the card handling device 100 of FIG. 1 is shown in FIG. 5E. Referring to FIGS. 5A-5E together, the card shuffling apparatus 204 may further include a card transfer system 502, and the card output portion 206 may include the card buffer area 214, a second frame assembly 503, a second pivoting axis 504, a second card feed system 506, a second card imaging system 508, and an actuation system 510.


Referring to FIGS. 4A and 5A-5E together, the card transfer system 502 of the card shuffling apparatus 204 may transfer playing cards from the plurality of compartments 406 of the multi-compartment carousel 402 to the card buffer area 214 of the card output portion 206 of the card handling device 100. In some embodiments, the card transfer system 502 may be configured to unload the plurality of compartments 406 in a compartment 406 by compartment 406 manner. For example, the card transfer system 502 may unload a first compartment 406 completely before unloading a second compartment 406. In some embodiments, the second compartment 406 may be a compartment 406 adjacent to the first compartment 406. In other embodiments, the second compartment 406 may be a randomly selected compartment 406 and may not necessarily be a compartment 406 adjacent to the first compartment 406. In some embodiments, the card transfer system 502 may not unload the plurality of compartments 406 compartment 406 by compartment 406 but, rather, may unload playing cards from the plurality of compartments 406 in a randomized (e.g., non-sequential) order. For example, the card transfer system 502 may unload one or more playing cards from a first compartment 406 without unloading other playing cards in the first compartment 406 and then may unload one or more playing cards from a second compartment 406 (e.g., with or without unloading other playing cards in the second compartment 406). In some embodiments, the card transfer system 502 may unload the playing cards one-at-a-time. In other embodiments, the card transfer system 502 may unload multiple playing cards at a time.


Referring to FIGS. 5A-5E, as discussed above, the card buffer area 214 of the card output portion 206 may be positioned at the interface 216 (FIG. 2) of the card shuffling apparatus 204 and the card output portion 206 of the card handling device 100. In some embodiments, the card buffer area 214 may be positioned within the card handling device 100 such that the card buffer area 214 is inaccessible to a dealer. The card buffer area 214 of the card output portion 206 may receive playing cards from the card shuffling apparatus 204 and may be able to hold a group of playing cards 512 temporarily prior to the playing cards being transferred to the substantially flat card output area 108. As discussed in further detail below, the card buffer area 214 may maintain a group of playing cards 512 having a number of playing cards within the range of nine to twenty-one.


The card buffer area 214 of the card output portion 206 may include a plate 514 (e.g., support), a spring 516 (e.g., a 516, bias), a first card guide 518, a second card guide 520, and a buffer pick-off roller 524. The plate 514 may include an upper surface 526 for supporting a group of playing cards 512 and an opposite bottom surface 527. The spring 516 may be attached to the bottom surface 527 of the plate 514, and a combination of the plate 514 and spring 516 may form a spring-loaded plate. For example, the spring 516 may push the plate 514 toward the buffer pick-off roller 524 and/or press the plate 514 against the group of playing cards 512. The buffer pick-off roller 524 may be oriented above the plate 514, and the card buffer area 214 may hold the group of playing cards 512 between the upper surface 526 of the plate 514 and the buffer pick-off roller 524. The first card guide 518 may be oriented above the plate 514 and proximate the buffer pick-off roller 524. The first card guide 518 may include a first portion 528 and a second portion 530. The first portion 528 of the first card guide 518 may extend from the buffer pick-off roller 524 in a direction toward the card shuffling apparatus 204, tangential to an outer circumference of the buffer pick-off roller 524, and parallel to the upper surface 526 of the plate 514 of the card buffer area 214. The second portion 530 of the first card guide 518 may extend upwards from the first portion 528 of the first card guide 518 (e.g., in a direction away from the card buffer area 214) from a side of the first portion 528 facing the card shuffling apparatus 204. The second portion 530 of the first card guide 518 may extend in a first plane 532 that is oriented at an acute angle relative to the upper surface 526 of the plate 514 of the card buffer area 214. The second portion 530 of the first card guide 518 may also form a first beveled edge 534 that leads to an area between the plate 514 and the buffer pick-off roller 524 and enables and guides insertion of playing cards on the top 544 of the group of playing cards 512 already present in the card buffer area 214. The second card guide 520 may be part of the plate 514 and extend downward from the plate 514 (e.g., in a direction away from the card buffer area 214) on a side of the plate 514 facing the card shuffling apparatus 204. The second card guide 520 may extend in a second plane 536 that is oriented at an acute angle relative to the upper surface 526 of the plate 514. The second card guide 520 may form a second beveled edge 538 that leads to an area between the plate 514 and buffer pick-off roller 524 and enables and guides insertion of playing cards at the bottom 542 of (e.g., beneath) the group of playing cards 512 already present in the card buffer area 214. Put another way, the first card guide 518 and second card guide 520 may extend, diverge, and/or fan outward from the space between the plate 514 and buffer pick-off roller 524 and may guide playing cards transferred by the card transfer system 502 from the multi-compartment carousel 402 into the space between the plate 514 and buffer pick-off roller 524.


The card buffer area 214 may adjust in size to accommodate different amounts of playing cards. For example, as discussed above, the plate 514 of the card buffer area 214 may be spring-loaded. As a result, the plate 514 may be able to translate generally up and down vertically relative to the card transfer system 502 of the card shuffling apparatus 204. Furthermore, the plate 514 may be able to translate relative to the buffer pick-off roller 524 such that the space between the plate 514 and the buffer pick-off roller 524 expands or contracts as the plate 514 translates. The volume of the card buffer area 214 may expand or contract responsive to playing cards being inserted into the card buffer area 214 by the card transfer system 502 or playing cards being removed from the card buffer area 214 by the buffer pick-off roller 524.


In some embodiments, the card buffer area 214 of the card output portion 206 may maintain a minimum number of playing cards in the card buffer area 214. For example, the card buffer area 214 of the card output portion 206 may maintain five to seven playing cards in the card buffer area 214. In some embodiments, the card buffer area 214 of the card output portion 206 may maintain seven to nine cards in the card buffer area 214. In some embodiments, the card buffer area 214 of the card output portion 206 may maintain more than nine cards in the card buffer area 214. For example, the card buffer area 214 of the card output portion 206 may maintain nine cards in the card buffer area 214. In some embodiments, the card buffer area 214 of the card output portion 206 may have a maximum number of playing cards that fit in the card buffer area 214 of the card output portion 206. For example, the maximum number of playing cards that fit in the card buffer area 214 may be within a range of ten to fifteen playing cards. In other embodiments, the maximum number of playing cards that fit in the card buffer area 214 may be within a range of fifteen to twenty playing cards. In other embodiments, the maximum number of playing cards that fit in the card buffer area 214 may be within a range of twenty to twenty-five playing cards. In some embodiments, the maximum number of playing cards that fit in the card buffer area 214 may be twenty-two playing cards.


Referring to FIGS. 1 and 5A-5E together, in some embodiments, the control system 105 may maintain a count of a number of playing cards that are present in the card buffer area 214. For example, the control system 105 may track how many playing cards are inserted into the card buffer area 214 by the card transfer system 502, and the control system 105 may track how many playing cards are removed from the card buffer area 214 by the second card feed system 506. By tracking movement of playing cards into and out of the card buffer area 214, the control system 105 may determine when the card buffer area 214 contains a minimum number of playing cards in the card buffer area 214. Furthermore, the control system 105 may determine when the card buffer area 214 contains a maximum number of cards in the card buffer area 214. Upon determination that the card buffer area 214 contains the minimum number of cards in the card buffer area 214, the control system 105 may add playing cards to the card buffer area 214 by having the card transfer system 502 insert additional playing cards into the card buffer area 214. Upon determination that the card buffer area 214 contains the maximum number of cards in the card buffer area 214, the control system 105 may temporarily stop the card transfer system 502 from adding playing cards to the card buffer area 214. The function and operation of the control system 105 are described in further detail in regard to FIG. 10.


In some embodiments, the card output portion 206 may have at least a first orientation and a second orientation relative to card shuffling apparatus 204 of the card handling device 100, as shown in FIGS. 5A-5E, respectively. Referring to FIGS. 5A and 5B, while the card output portion 206 is in the first orientation, the card transfer system 502 of the card shuffling apparatus 204 may insert playing cards into the card buffer area 214 of the card output portion 206 at a bottom 542 of (e.g., beneath) the group of playing cards 512 already present in the card buffer area 214. For example, the card transfer system 502 may remove one or more playing cards from one of the plurality of compartments 406 (FIG. 4A) of the multi-compartment carousel 402 (FIG. 4A) and may insert the playing card into the card buffer area 214 by sliding the playing card against the second beveled edge 538 of the second card guide 520 and the upper surface 526 of the plate 514 until the playing card is between the plate 514 and buffer pick-off roller 524 of the card buffer area 214. In other words, the card transfer system 502 may remove a playing card from one of the plurality of compartments 406 (FIG. 4A) of the multi-compartment carousel 402 (FIG. 4A) and may slide a leading edge of the playing card against the second beveled edge 538 of the second card guide 520 until the playing card presses up against a bottom surface of a bottommost card of the group of playing cards 512. The card transfer system 502 may continue to slide the playing card between the bottom surface of a bottommost card of the group of playing cards 512 and the upper surface of the plate 514 until the playing card is at least substantially aligned (e.g., nested) with the other playing cards in the group of playing cards 512. Such an operation may result in inserting the playing card at the bottom 542 of the group of playing cards 512. Furthermore, while in the first orientation, the buffer pick-off roller 524 of the second card feed system 506 may remove playing cards from a top 544 of the group of playing cards 512 in the card buffer area 214 and the group of playing cards 512 may be transported to the substantially flat card output area 108 of the card handling device 100 in a same order in which the playing cards were inserted into the card buffer area 214 by the card transfer system 502.


Referring to FIGS. 5C and 5D, while the card output portion 206 is in the second orientation, the card transfer system 502 may insert playing cards into the card buffer area 214 of the card output portion 206 at a top 544 of the group of playing cards 512 already present in the card buffer area 214. For example, the card transfer system 502 may remove one or more playing cards from one of the plurality of compartments 406 (FIG. 4A) of the multi-compartment carousel 402 (FIG. 4A) and may insert the playing card into the card buffer area 214 by sliding the playing card against the first beveled edge 534 of the second portion 530 of the first card guide 518 and the first portion 528 of the first card guide 518 until the playing card is between the plate 514 and buffer pick-off roller 524 of the card buffer area 214. In other words, the card transfer system 502 may remove a playing card from one of the plurality of compartments 406 (FIG. 4A) of the multi-compartment carousel 402 (FIG. 4A) and may slide a leading edge of the playing card against the first beveled edge 534 of the second portion 530 of the first card guide 518 until the playing card presses up against a top surface of an uppermost card of the group of playing cards 512. The card transfer system 502 may continue to slide the playing card between the top surface of an uppermost card of the group of playing cards 512 and the first portion 528 of the first card guide 518 until the playing card is at least substantially aligned (e.g., nested) with the other playing cards in the group of playing cards 512. Such an operation may result in positioning the playing card at the top 544 of the group of playing cards 512. As a result, any playing cards inserted into the card buffer area 214 at the top 544 of the group of playing cards 512 already in the card buffer area 214 may be removed by the buffer pick-off roller 524 of the second card feed system 506 prior to playing cards that were already in the card buffer area 214. Accordingly, while in the second orientation, the card buffer area 214 of the card handling device 100 may be able to perform an overtake function where a playing card withdrawn from the multi-compartment carousel 402 (FIG. 4A) may pass up (e.g., overtake or pre-empt) the group of playing cards 512 that is already in the card buffer area 214. In some embodiments, only one playing card at a time will pass up the group of playing cards 512 already in the card buffer area 214. In other embodiments, multiple playing cards at a time will pre-empt the group of playing cards 512 already in the card buffer area 214.


In some embodiments, the card output portion 206 may be configured to move between the first orientation and the second orientation in an at least substantially random or automatic (e.g., without human intervention) manner. For example, the card output portion 206 may be fully controlled by the control system 105 (FIG. 1) such that a dealer administering the card handling device 100 at a table 212 (FIG. 2) and/or any players playing at the table 212 (FIG. 2) are unaware of the movement of the card output portion 206 and the placement order of the cards in the card buffer area 214. In some embodiments, the control system 105 may include a random number generator and may determine when to move the card output portion 206 between the first orientation and the second orientation based on the numbers generated by the random number generator. In some embodiments, a default position of the card output portion 206 may be in the first orientation. For example, the card output portion 206 may be typically oriented in the first orientation and may just move into the second orientation temporarily as determined by the control system 105.


Referring to FIGS. 1 and 5A-5E together, in some embodiments, the card output portion 206 may be moved back and forth between the first orientation and second orientation by the actuation system 510 of the card output portion 206. The actuation system 510 may be mounted at one end to the frame structure 102 of the card handling device 100 and at another end to the second frame assembly 503 of the card output portion 206 and may be able to extend and contract. Furthermore, the actuation system 510 may be controlled by the control system 105 of the card handling device 100. When the actuation system 510 extends or retracts, the actuation system 510 may move at least substantially the entire card output portion 206 of the card handling device 100 relative to the card shuffling apparatus 204 of the card handling device 100. In some embodiments, the actuation system 510 may move the card output portion 206 such that the card buffer area 214 of the card output portion 206 moves at least partially in a vertical direction relative to the card transfer system 502 of the card shuffling apparatus 204. As a result, when the actuation system 510 moves the card buffer area 214 of the card output portion 206 back and forth vertically, the card transfer system 502 of the card shuffling apparatus 204 may be able to insert playing cards from the card shuffling apparatus 204 at both the top 544 and bottom 542 of the group of playing cards 512 in the card buffer area 214. In some embodiments, the actuation system 510 may include one or more of an electronic piston, electronic solenoid, and motor spindle. In other embodiments, the actuation system 510 may be pneumatically operated.


In some embodiments, the card output portion 206 may be rotatable about the second pivoting axis 504 relative to the card shuffling apparatus 204 of the card handling device 100. For example, the second pivoting axis 504 may include a second shaft 546 rotatably mounted at both ends to the frame structure 102 of the card handling device 100. The second shaft 546 of the second pivoting axis 504 may extend axially in a direction substantially parallel to a table surface 210 (FIG. 2) of a table 212 (FIG. 2) to which the card handling device 100 may be mounted. In some embodiments, the second pivoting axis 504 of the card output portion 206 may be oriented proximate the substantially flat card output area 108 of the card handling device 100. When the actuation system 510 moves the card output portion 206, the card output portion 206 may rotate about the second pivoting axis 504 and the card buffer area 214 of the card output portion 206 may move at least partially in a vertical direction relative to the card shuffling apparatus 204, which, as a result, allows the card transfer system 502 to insert playing cards at the top 544 and bottom 542 of the group of playing cards 512 in the card buffer area 214. As described above, allowing the card transfer system 502 to insert playing cards at the top 544 of the group of playing cards 512 in the card buffer area 214 enables playing cards to overtake the group of playing cards 512 in the card buffer area 214 as part of a playing card bypass process.


Having playing cards overtake the group of playing cards 512 in the card buffer area 214 may assist in the prevention of counting cards by players. For example, several methods of counting cards rely on knowing what rankings of playing cards in a group of playing cards 512 (e.g., in a selected number of decks) remain to be dealt, have been dealt, and/or remain in the shoe before the deck or decks of cards are reshuffled as a batch or recycled through a continuous shuffler. As mentioned above, the card shuffling apparatus 204 of the card handling device 100 may be a continuous shuffling apparatus and may operate to at least partially shuffle used playing cards back into the plurality of compartments 406 of the multi-compartment carousel 402 and the card buffer area 214 of the card output portion 206 without unloading all of the cards at the end of a round of play. Furthermore, by having a playing card overtake (e.g., bypass) the group of playing cards 512 in the card buffer area 214, a playing card used in a previous hand has a chance of being dealt at least almost immediately after reinsertion into the card handling device 100. As a result, it may be more difficult for a player to know what playing cards to expect or not to expect in a next hand. When using a card handling device that holds a group of cards in a buffer area and does not have playing cards overtake other playing cards in the shoe or card shuffling apparatus, a player can expect playing cards from a previous hand to not be dealt for at least a certain number of playing cards (e.g., a minimum number of playing cards in a card buffer area 214 or playing cards already collected in a shoe). However, a player playing at a table 212 (FIG. 2) using the card handling device 100 of the present disclosure cannot assume that playing cards of the previous hand will not be dealt for a certain number of playing cards. In fact, having a playing card randomly overtake the group of playing cards 512 in the card buffer area 214 may make it nearly impossible for a player to effectively count cards using known methods. Accordingly, having playing cards overtake the group of playing cards 512 in the card buffer area 214 further randomizes the order of the playing cards that are dealt from the substantially flat card output area 108 and may help to maintain a house advantage in card games where card counting is a frequent problem.


Referring again to FIGS. 5A-5E, the second card feed system 506 of the card output portion 206 may include a second card pathway 540 (e.g., pathway along which playing cards move through the card output portion 206). The second card pathway 540 may lead from the card buffer area 214 of the card handling device 100 to the substantially flat card output area 108 of the card handling device 100. The buffer pick-off roller 524 of the second card feed system 506 may remove playing cards from the card buffer area 214 from a top 544 of a group of playing cards 512 collected in the card buffer area 214 of the card output portion 206. The second card feed system 506 may further have additional pairs of rollers 548, 550, 552, 554, 556, that may displace playing cards from the card buffer area 214 to the substantially flat card output area 108 of the card handling device 100. For example, as described above, the buffer pick-off roller 524 of the second card feed system 506 may remove playing cards from the top 544 of the group of playing cards 512 in the card buffer area 214 and the additional rollers 548, 550, 552, 554, 556, may transport the playing cards to the substantially flat card output area 108. In some embodiments, the second card feed system 506 of the card output portion 206 may transport playing cards to the substantially flat card output area 108 one-at-a-time. In some embodiments, the second card feed system 506 may not transport another playing card to the substantially flat card output area 108 until a playing card present in the substantially flat card output area 108 (e.g., previously sent to the substantially flat card output area 108) is taken out of the substantially flat card output area 108 (e.g., dealt or otherwise removed by a dealer). In other words, until the control system 105 receives a signal indicating the absence of a playing card in the substantially flat card output area 108, another playing card may not be delivered to the substantially flat card output area 108.


Furthermore, because of the overtake function of the card handling device 100 and because the playing cards may be sent one-at-a-time to the substantially flat card output area 108, there may not be a collection of playing cards within the card handling device 100 that cannot be changed prior to sending a next playing card to the substantially flat card output area 108. As a result, randomization of the playing cards is further increased by the card handling device 100 of the current disclosure when compared with conventional card shufflers.


In some embodiments, the second card imaging system 508 may be oriented along the second card pathway 540 of the second card feed system 506. The second card feed system 506 may transport playing cards past the second card imaging system 508, and the second card imaging system 508 may capture identifying information of each playing card as each playing card moves along the second card pathway 540 before insertion in the substantially flat card output area 108. The second card imaging system 508 may be similar to the first card imaging system 308 and may comprise any of the components described above. For example, the second card imaging system 508 may include a second sensor 509, etc. Referring to FIGS. 3, 5A, and 5B together, as noted above, the first card imaging system 308 and the second card imaging system 508 may be used together to keep an inventory of the playing cards being sent through the card handling device 100. For example, the control system 105 (FIG. 1) may take a first inventory of the playing cards as the playing cards are inserted into the card shuffling apparatus 204, and the control system 105 (FIG. 1) may take a second inventory of the playing cards as the playing cards are inserted into substantially flat card output area 108. Furthermore, the first inventory and the second inventory may be compared and contrasted to determined behaviors of the card handling device 100, effectiveness of the card shuffling apparatus 204, and a randomness of the playing cards relative to how the playing cards entered the card shuffling apparatus 204. Moreover, the first inventory and second inventory may be used to detect tampering, cheating, or an absence of playing cards in decks handled by the card handling device 100.



FIG. 6 is a perspective view of the substantially flat card output area 108 of the card handling device 100. The substantially flat card output area 108 (e.g., substantially flat card delivery area or substantially flat card shoe) of the card handling device 100 may include an interface portion 602, a cover 604, a sensor 606, and an outlet 608. The cover 604 of the substantially flat card output area 108 may be oriented above the interface portion 602 and may cover at least a portion of the interface portion 602 of the substantially flat card output area 108. The cover 604 and the interface portion 602 of the substantially flat card output area 108 may define the outlet 608 between the cover 604 and the interface portion 602. Furthermore, the second card feed system 506 (FIG. 5A) of the card output portion 206 may be able to send playing cards one-at-a-time through the outlet 608.


The interface portion 602 of the substantially flat card output area 108 may have a lower surface 610, an opposite at least substantially flat draw surface 612, a first end 614, and an opposite second end 616. The draw surface 612 of the interface portion 602 may be able to support playing cards that are sent into the substantially flat card output area 108 from the second card feed system 506 (FIG. 5A) of the card output portion 206. The draw surface 612 of the interface portion 602 may be defined at an acute angle β relative to the lower surface 610 of the interface portion 602 (or a surface of the table surface 210 of the table 212 to which the card handling device 100 is mounted as shown in FIG. 2). In other words, the interface portion 602 of the substantially flat card output area 108 may have an at least general wedge shape. In some embodiments, the acute angle β may be within a range of 3° to 5°. In other embodiments, the acute angle β may be within a range of 5° to 10°. In other embodiments, the acute angle β may be within a range of 10° to 20°. In other embodiments, the acute angle β may be at least about 10°. The acute angle β may be selected in order to provide the dealer the greatest amount of comfort while manually removing cards. The second end 616 of the interface portion 602 of the substantially flat card output area 108 may be attached to or may be proximate to the card output portion 206 of the card handling device 100. The first end 614 of the interface portion 602 of the substantially flat card output area 108 may be oriented distal to the card output portion 206 of the card handling device 100.


When the card handling device 100 is mounted to a table 212 (FIG. 2), the lower surface 610 of the interface portion 602 of the substantially flat card output area 108 may rest on a table surface 210 (FIG. 2) of the table 212 (FIG. 2), and the draw surface 612 of the interface portion 602 of the may be oriented at the acute angle β relative to the table surface 210 (FIG. 2). Having the draw surface 612 of the interface portion 602 oriented at a relatively small acute angle β relative to the surface of the table 212 (FIG. 2) may decrease an extent to which dealers are required to twist their wrists and lift their hands when drawing playing cards from the substantially flat card output area 108 when compared to conventional card shoes. As a result, the substantially flat card output area 108 may increase a speed at which a dealer may deal playing cards to players, which, in turn, may increase a pace at which games may be administered at a table 212 (FIG. 2). Furthermore, the substantially flat card output area 108 may, over time, decrease fatigue that dealers may experience in their wrists and/or hands when administering a game at a table 212 (FIG. 2).


The cover 604 of the substantially flat card output area 108 may have a base portion 618 and two laterally spaced arm portions 620, 622 extending from the base portion 618. The base portion 618 of the cover 604 may be oriented proximate the second end 616 of the interface portion 602 of the substantially flat card output area 108 and may extend above the second end 616 of the interface portion 602 of the substantially flat card output area 108. The two arm portions 620, 622 of the cover 604 may extend from the base portion 618 of the cover 604 toward the first end 614 of the interface portion 602 of the substantially flat card output area 108. The two arm portions 620, 622 of the cover 604 may be separated from each other by a cutout 624 extending vertically though the cover 604. For example, the cover 604 may have an at least general U-shape when viewed from a top of the cover 604 of the substantially flat card output area 108, wherein the base portion 618 forms the bottom part of the U and the two arm portions 620, 622 form the two extending arms of the U. In some embodiments, the cutout 624 in the cover 604 may have a semicircular shape. In other embodiments, the cutout 624 in the cover 604 may have a rectangular shape. The cutout 624 may serve to expose portions of the playing cards that are sent to the substantially flat card output area 108 and may make the playing cards more accessible to dealers. In some embodiments, an interface of the cutout 624 of the cover 604 with the base portion 618 and two arm portions 620, 622 of the cover 604 may define a chamfered edge 626, which may make it more comfortable for a dealer to draw a playing card from the substantially flat card output area 108.


In some embodiments, each arm portion 620, 622 of the two arm portions 620, 622 of the cover 604 of the substantially flat card output area 108 may be at least partially separated from the draw surface 612 of the interface portion 602 of the substantially flat card output area 108 by an opening 628, 630. In other words, the two arm portions 620, 622 may extend from the base portion 618 of the cover 604 and may overhang at least a portion of the interface portion 602 of the substantially flat card output area 108 in a cantilevered manner. The openings 628, 630 separating each arm portion 620, 622 of the two arm portions 620, 622 of the cover 604 from the draw surface 612 of the interface portion 602 may allow playing cards to pass under the two arm portions 620, 622 and through the openings 628, 630. In other words, As a result, the openings 628, 630 may permit playing cards that are sent into the substantially flat card output area 108 by the second card feed system 506 (FIG. 5A) to be drawn from the outlet 608 of the substantially flat card output area 108 in multiple, different, at least substantially horizontal directions. A range of directions comprising an included angle in which playing cards may be drawn from the outlet 608 of substantially flat card output area 108 may be characterized as a “drawable angle.” For example, playing cards may be drawn from the outlet 608 of the substantially flat card output area 108 in any direction extending within the drawable angle. The drawable angle may be within a third plane 632 extending along the draw surface 612 of the interface portion 602 of the substantially flat card output area 108 and may be centered with respect to a center longitudinal axis 634 of the substantially flat card output area 108 such that half of the drawable angle extends to each side of the center longitudinal axis 634. In some embodiments, the drawable angle may be at least 60°. In other words, a first direction in which a playing card may be drawn in the drawable angle may be offset at least 60° in the third plane 632, which may contain a majority of the draw surface 612, from a second direction in which a playing card may be drawn in the drawable angle. In some embodiments, the drawable angle may be at least 90°. In some embodiments, the drawable angle may be at least 135°. In some embodiments, the drawable angle may be 180° or greater. As a result, playing cards may be drawn from the outlet 608 of the substantially flat card output area 108 in a plurality of directions including directions that are perpendicular to or even are oriented at obtuse angles relation to each other.


Stated another way, the openings 628, 630 may permit playing cards that are sent to the substantially flat card output area 108 by the second card feed system 506 (FIG. 5A) to be drawn from the outlet 608 of the substantially flat card output area 108 in multiple at least substantially horizontal directions without first being drawn in a direction collinear to the second card pathway 540 (FIG. 5A) of the card output portion 206 or parallel to the center longitudinal axis 634 of the substantially flat card output area 108. In other words, once a playing card comes to rest in the substantially flat card output area 108 after being sent to the substantially flat card output area 108 by the second card pathway 540 (FIG. 5A) of the card output portion 206, any initial draw movement made by a dealer to draw the playing card from the outlet 608 of the substantially flat card output area 108 may be in in any direction extending within the drawable angle.


Furthermore, in some embodiments, the draw surface 612 of the interface portion 602 of the substantially flat card output area 108 may not include ridges or walls obstructing the openings 628, 630. Put another way, the draw surface 612 of the interface portion 602 may be continuously planar and may extend under the two arm portions 620, 622 and completely through the openings 628, 630. Thus, playing cards may not have to pass over any ridges or walls when passing through the openings 628, 630 and being drawn from the draw surface 612 of the interface portion 602 of the substantially flat card output area 108.


Having a substantially flat card output area 108 that allows dealers to draw playing cards from the outlet 608 of the substantially flat card output area 108 within a range of directions may be advantageous over other shoes because the substantially flat card output area 108 may reduce a need to rearrange an orientation of the shoe of a card handling device 100 to meet a dealer's card drawing preference or physical limitation. Furthermore, the substantially flat card output area 108 may reduce a need to exchange shoes of a card handling device that is mounted to a table 212 (FIG. 2) in order to accommodate a dealer's card drawing preference. Moreover, the substantially flat card output area 108 may increase positions at which the dealer may comfortably be situated at a table 212 (FIG. 2) while administering a game at a table 212 (FIG. 2). Thus, the substantially flat card output area 108 may enable a more universal card shoe that does not require adjustments as dealers change at a given table 212 (FIG. 2). Additionally, the substantially flat card output area 108 may increase an efficiency of the dealer and may decrease down time at a table 212 (FIG. 2), such as, time needed to change out or adjust a shoe, which may, in turn, increase profitability at a table 212 (FIG. 2).


The sensor 606 of the substantially flat card output area 108 may be oriented in the interface portion 602 of the substantially flat card output area 108 and may be in communication with the control system 105 (FIG. 1). The sensor 606 may sense when a playing card is present or absent from the substantially flat card output area 108. In some embodiments, the sensor 606 may sense the movement of a playing card across the draw surface 612 of the interface portion 602 of the substantially flat card output area 108. In other embodiments, the sensor 606 may sense the presence or absence of a playing card. For example, the sensor 606 may include an infrared sensor. In some embodiments, during operation, when the sensor 606 of the substantially flat card output area 108 senses an absence of a playing card in the substantially flat card output area 108 or the act of a dealer drawing the playing card from the substantially flat card output area 108, the control system 105 (FIG. 1) may direct the second card feed system 506 (FIG. 5A) of the card output portion 206 to remove a playing card from the card buffer area 214 (FIG. 5A) of the card output portion 206 and to send the playing card into the substantially flat card output area 108. In some embodiments, during operation, when the sensor 606 of the substantially flat card output area 108 senses the presence of a playing card in the substantially flat card output area 108, the control system 105 (FIG. 1) may direct the second card feed system 506 of the card output portion 206 to stop sending playing cards to the substantially flat card output area 108. For example, as described above, the card handling device 100 may send playing cards to the substantially flat card output area 108 one-at-a-time and may not send another playing card to the substantially flat card output area 108 until a previously sent playing card has been removed from the substantially flat card output area 108.


Referring to FIGS. 1, 2, and 6 together, the overall flat structure of the substantially flat card output area 108 and the orientation of the card intake area 208 of the card input portion 202 (e.g., proximate the substantially flat card output area 108) may permit a majority of the card handling device 100 to the mounted beneath a table surface 210 of a table 212 to which the card handling device 100 is mounted.



FIG. 7 is a partial side view of the card handling device 100 of FIG. 1. The card transfer system 502 of the card shuffling apparatus 204 may at least partially define a third card pathway 702 (e.g., a pathway along which playing cards move through the card transfer system 502 when leaving the multi-compartment carousel 402 of the card shuffling apparatus 204 and entering the card buffer area 214). In some embodiments, the second card pathway 540 of the card output portion 206 and the third card pathway 702 of the card transfer system 502 may have an included angle ϕ defined between the second card pathway 540 and the third card pathway 702. In some embodiments, the angle ϕ may be between within a range of 90° and 175°. In some embodiments, the angle ϕ may be between within a range of 125° and 165°. Furthermore, in some embodiments, the angle ϕ may be different when the card output portion 206 is oriented in the first orientation than when the card output portion 206 is oriented in the second orientation.


In other words, playing cards may first travel along the third card pathway 702 while moving through the card transfer system 502 of the card shuffling apparatus 204 and to the card buffer area 214. When drawn from the card buffer area 214, the cards may then be deflected into traveling (e.g., urged to travel) along the second card pathway 540 when leaving the card buffer area 214 and traveling through the card output portion 206. Put another way, playing cards may travel in a first direction when entering into the card buffer area 214 and may travel in a second different direction when leaving the card buffer area 214. In some embodiments, the first direction may define an obtuse angle with the second direction.


In some embodiments, the third card pathway 702 may extend in a direction of intended card movement that at least partially declines relative to the table surface 210 (FIG. 2) of the table 212 (FIG. 2), and the second card pathway 540 may extend in a direction that at least partially inclines relative to the table surface 210 (FIG. 2) of the table 212 (FIG. 2). In other embodiments, the third card pathway 702 may extend in the direction of intended card movement that is least substantially horizontal, and the second card pathway 540 may extend in the direction of intended card movement that at least partially inclines relative to the table surface 210 (FIG. 2) of the table 212 (FIG. 2).



FIG. 8 shows a flow diagram of a process 801 in which the card handling device 100 may shuffle playing cards. Referring to FIGS. 2, 3, 4A, and 8 together, playing cards may be loaded into the card intake area 208 of the card input portion 202 of the card handling device 100, as represented in action 800. The playing cards may be transported by the first card feed system 306 from the card intake area 208 and through the card input portion 202 along the first card pathway 312, as represented by action 802. Along the first card pathway 312, the first card imaging system 308 may capture a first image of each playing card, as represented by action 804. The playing cards may be inserted into the plurality of compartments 406 of the multi-compartment carousel 402, as represented by action 806. The playing cards may be temporarily stored within the plurality of compartments 406 of the multi-compartment carousel 402.


Referring to FIGS. 4A, 5A-5E, and 8 together, the playing cards may be withdrawn from the plurality of compartments 406 of the multi-compartment carousel 402 by the card transfer system 502, as represented by action 808. The card transfer system 502 may insert the playing cards into the card buffer area 214 of the card output portion 206 of the card handling device 100, as represented by action 810. A group of playing cards 512 may be formed within the card buffer area 214 by inserting cards into the card buffer area 214 with the card transfer system 502, as represented by action 812.


In some embodiments, after a group of playing cards 512 has been positioned within the card buffer area 214, the card transfer system 502 may insert at least one playing card from the plurality of compartments 406 of the multi-compartment carousel 402 into the card buffer area 214 of the card output portion 206 at the bottom 542 of the group of playing cards 512, as represented by action 814. In some embodiments, after a group of playing cards 512 has been positioned within the card buffer area 214, the card transfer system 502 may insert at least one playing card from the plurality of compartments 406 of the multi-compartment carousel 402 into the card buffer area 214 of the card output portion 206 at the top 544 of the group of playing cards 512, as represented by action 816. In some embodiments, after at least one playing card has been inserted at the top 544 or bottom 542 of the group of playing cards 512, the orientation of the card output portion 206, and as a result, the orientation of the card buffer area 214 relative to the card shuffling apparatus 204 may be changed, as represented by action 815. The orientation of the card buffer area 214 may be changed (e.g., back and forth, continuously, intermittently, etc.) to enable the card transfer system 502 to insert playing cards at both of the top 544 and the bottom 542 of the group of playing cards 512 formed in the card buffer area. For example, the orientation of the card output portion 206 may be changed from the first orientation to the second orientation or from the second orientation to the first orientation.


Playing cards may be removed from the card buffer area 214 by the pick-off roller 524 from the top 544 of the group of playing card 512, as represented by action 818. The playing cards may be moved through the card output portion 206 by the second card feed system 306 from the card buffer area 214 and along the second card pathway 540, as represented by action 820. Along the second card pathway 540, the second card imaging system 508 may capture a second image of each playing card, as represented by action 822. The playing cards may be delivered to the substantially flat card output area 108, where the playing cards may be drawn from the substantially flat card output area 108 in multiple, different, at least substantially horizontal directions relative to the second card pathway 540, as represented by the action 824.



FIG. 9 is an enlarged perspective view of the card transfer system 502. The card transfer system 502 may include an ejection assembly 902 for removing cards from the multi-compartment carousel 402 and a discharge feeder assembly 904 for inserting playing cards into the card buffer area 214. The ejection assembly 902 may include at least one pusher arm 906 and at least one post 908. The at least one pusher arm 906 may be pivotally coupled to the at least one post 908 and may be configured to pivot (e.g., rotate) about the at least one post 908. The at least one pusher arm 906 may extend longitudinally from the at least one post 908 in a direction at least substantially perpendicular to a direction in which the at least one post 908 extends. When the at least one pusher arm 906 pivots about the at least one post 908, a distal end 910 of the at least one pusher arm 906 (e.g., the end of at least one pusher arm not coupled to the at least one post 908) may translate proximate the plurality of compartments 406 of the multi-compartment carousel 402. In some embodiments, the distal end 910 of the at least one pusher arm 906 may at least partially translate along the third card pathway 702 of the card transfer system 502. During translation, the distal end 910 of the at least one pusher arm 906 may be configured to catch an edge of a side (e.g., lateral side) of at least one playing card located in a compartment 406 of the plurality of compartments 406 of the multi-compartment carousel 402. For example, portions of the playing cards may extend longitudinally from both sides of the plurality of compartments 406, and the distal end 910 of the at least one pusher arm 906 may catch portions of the playing cards that extend from the plurality of compartments 406 when the at least one pusher arm 906 pivots about the at least one post 908. Furthermore, the at least one pusher arm 906 may be configured to push the at least one playing card from the compartment 406 and push the at least one playing card along the third card pathway 702 of the card transfer system 502 and into the discharge feeder assembly 904 of the card transfer system 502.


In some embodiments, the card transfer system 502 may include an ejection assembly 902 on each lateral side of the multi-compartment carousel 402. For example, the card transfer system 502 may include a first ejection assembly of a first side of the multi-compartment carousel 402 and a second ejection assembly on a second side of the multi-compartment carousel 402. Furthermore, the first and second ejection assemblies may cooperate (e.g., be synchronized) to remove the at least one card from the plurality of compartments 406 of the multi-compartment carousel 402. For example, a first pusher arm of the first ejection assembly may catch a portion of the at least one playing card protruding from a first side of a compartment 406 and a second pusher arm of the second ejection assembly may catch a portion of the at least one playing card protruding from a second side of a compartment 406. Together, the first and second ejection assemblies may push the at least one playing card from the compartment 406 and along the third card pathway 702 of the card transfer system 502 and into the discharge feeder assembly 904 of the card transfer system 502.


The discharge feeder assembly 904 may include two discharge rollers 912, 914 configured to grip at least one playing card between the two discharge rollers 912, 914. For example, the two discharge rollers 912, 914 may be configured to grip playing cards that are pushed out of the plurality of compartments 406 of the multi-compartment carousel 402 by the ejection assembly 902 of the card transfer system 502. In other words, the ejection assembly 902 may push cards out of the plurality of compartments 406 of the multi-compartment carousel 402 and then may push the playing cards between the two discharge rollers 912, 914.


The two discharge rollers 912, 914 may rotate relative to one another, grip the playing cards between each other, and insert the playing cards into the card buffer area 214 of the card output portion 206. In some embodiments, one of the two discharge rollers 912, 914 may freely rotate and another of the two discharge rollers 912, 914 may be coupled to a gear and belt system 916 that is operated by a discharge motor 918. The gear and belt system 916 and discharge motor 918 may rotate the another of the two discharge rollers 912, 914 and may be controlled by the control system 105 (FIG. 1). In some embodiments, both of the two discharge rollers 912, 914 may be coupled to the gear and belt system 916 and the discharge motor 918.


In some embodiments, the card transfer system 502 may be configured to move multiple playing cards at a time (e.g., together or in sequence). For example, the card transfer system 502 may move at least two playing cards stacked on top of each other at a time. Furthermore, the card transfer system 502 may be able to move at least one playing card with the ejection assembly 902 while simultaneously moving at least another card with the discharge feeder assembly 904. In other embodiments, the card transfer system 502 may move a single playing card at a time.

Furthermore, the control system 105 may communicate electrically with additional sensors 928 that may be disposed along the first, second, and third card pathways 312, 540, and 702, respectively. For example, additional sensors 928 may include sensors in the card intake area 208, proximate the pairs of rollers 316, 318, 320, proximate the discharge rollers 912, 914, proximate the buffer pick-off roller 524, or proximate the additional rollers 548, 550, 552, 554, 556, etc. In some embodiments, an additional sensor 928 may be included in front of or behind each pair of rollers (e.g., pair of rollers 316) along a respective card pathway for tracking movement of playing cards throughout the card handling device 100. Furthermore, in some embodiments, an additional sensor 928 may be included in the card intake area 208 to sense a presence or absence of playing cards in the card intake area 208. As discussed previously, each of the above listed sensors may be in electrical communication with the control system 105. Furthermore, the control system 105 may be in electrical communication with each of the controllers (e.g., motors or actuators) of each of the above listed pairs of rollers, the actuation system 510, card shuffling apparatus 204, and card transfer system 502.


In some embodiments, the card handling device 100 may be incorporated into a table game management system by connecting or otherwise providing communication between the control system 105 of the card handling device 100 and a network 930. For example, a data port (not shown) on the card handling device 100 may be used to provide electrical communication to the network 930 through a conductive wire, cable, or wireless connection. The network 930 may communicate with the electronic signal processor 922 of the control system 105. In additional embodiments, the network 930 may communicate directly with one or more above-described controllers of the card handling device 100, or with both the electronic signal processor 922 of the control system 105 and the above-described controllers of the card handling device 100.
