Abstract

The present invention provides an apparatus and method for moving playing cards from a first group of cards into plural hands of cards, wherein each of the hands contains a random arrangement of cards. The apparatus comprises a card receiver for receiving the first group of cards, a single stack of card-receiving compartments generally adjacent to the card receiver, the stack generally vertically movable, an elevator for moving the stack, a card-moving mechanism between the card receiver and the stack, and a microprocessor that controls the card-moving mechanism and the elevator so that an individual card is moved into an identified compartment. The number of compartments receiving cards and the number of cards moved to each compartment may be selected. An apparatus for feeding cards, comprising a surface for supporting a stack of cards, a feed roller with a frictional outer surface, a drive mechanism for causing rotation of the feed roller, a pair of speed-up rollers to advance the cards out of the feed roller, and a clutch mechanism for disengaging the feed roller from the drive mechanism as the card comes into contact with the speed up rollers.

Claims

1-35. -35. (Cancelled)

36. An automatic card shuffling and hand forming device, comprising:

a card receiver;

a card shuffling mechanism;

a card moving mechanism capable of moving cards from the card receiver into the card shuffling mechanism;

a hand-forming mechanism;

an output tray;

a second card moving mechanism that moves formed hands into the output tray; and

a processor for controlling the operation of the device, and when a first hand of randomized cards is delivered to output tray, and when the hand of cards is manually removed, another hand is automatically delivered to the output tray until either a maximum number of hands is delivered, or a signal is received by the processor to cease delivering hands.

37. The device of claim 36, and further comprising a dealer input button that generates the signal that causes the processor to instruct the device to cease delivering hands.

38. The device of claim 36, wherein a maximum number of hands is equal to a number of player positions on the table.

39. The device of claim 36, wherein a maximum number of hands is equal to a number of player positions on the table plus a dealer hand.

40. The device of claim 36, wherein the card infeed tray comprises a downwardly angled floor surface, and further comprising a sliding block to urge cards down the angled floor surface towards the card moving mechanism.

41. The device of claim 36, wherein the card shuffling mechanism comprises a vertically disposed stack including a plurality of horizontally disposed card-receiving compartments and an elevator capable of moving the stack generally vertically in order to align a compartment with the card moving mechanism.

42. The device of claim 36, wherein the output tray further comprises a sensor for sensing at least one of the absence and the presence of cards.

43. The device of claim 37, and when the dealer input button is activated, all remaining cards in the device are unloaded onto the output tray.

44. The device of claim 41, wherein the processor randomly selects or identifies the compartment to receive each card in an initial group of cards to be shuffled and formed into hands.

45. The device of claim 36, wherein the card moving mechanism comprises a card pick-up roller assembly.

46. The device of claim 45, and further comprising a speed-up system.

47. The device of claim 45, wherein the pick-up roller assembly further comprises a one-way clutch mechanism.

48. The device of claim 36, wherein the second card moving mechanism comprises an unloading pusher.

49. The device of claim 36, wherein a first hand of cards is delivered to the output tray in response to an operator input.

50. The device of claim 36, wherein a first hand of cards is delivered to the output tray automatically.

60. The apparatus of claim 36, wherein the card moving mechanism moves cards individually from the card receiver into the card shuffling mechanism.

51. An automatic card shuffling and hand forming device, comprising:

a card receiver;

a card shuffling mechanism;

a card moving mechanism capable of moving cards from the card receiver into the card shuffling mechanism;

a hand-forming mechanism;

an output tray;

a second card moving mechanism that moves a formed hand as a group to the output tray;

a dealer input; and

a processor for controlling the operation of the device, wherein a first hand of randomized cards is automatically delivered to the output tray.

52. The device of claim 51, wherein when the first hand of cards is manually removed from the output tray, another hand of cards is automatically delivered to the output tray.

53. The device of claim 51, wherein the device automatically delivers subsequent hands of cards until the processor receives a second signal from the dealer input.

61. The device of claim 51, wherein the card moving mechanism moves cards individually from the card receiver into the card shuffling mechanism.

54. A method of randomizing and forming subgroups of cards from a larger group of cards, comprising:

providing a larger group of cards to be randomized;

providing a card-handling device capable of randomizing cards, forming subgroups of cards and delivering subgroups of cards to an output tray;

inserting the larger group of cards into the device;

randomizing an order of the cards;

forming subgroups of cards; and

automatically delivering a first subgroup of cards as a group to an output tray.

55. The method of claim 54 and further comprising the step of automatically delivering an additional group of cards after the first subgroup is manually removed.

56. The method of claim 55, and delivering additional subgroups of cards as previously delivered hands are removed until either a maximum number of hands has been delivered or an instruction is received from a dealer input device to cease forming hands.

57. The method of claim 56, wherein after the instruction is received, all remaining cards in the device are unloaded.

58. The method of claim 54, wherein the randomization and hand forming steps occur simultaneously.

59. The method of claim 54, wherein the subgroup of cards comprises a hand of cards.
