A card-feeding device for feeding cards into a card-handling device is disclosed. Examples of card-handling devices include shufflers, card sorters, card delivery devices and card verification devices. The device includes a card infeed area that supports a stack of cards. The card infeed area has a card support surface. Included in the device is a card-removing system that removes cards individually from the bottom of the stack. A pivoting arm presses against a card at the top of the stack. At least one sensor is provided that detects at least one of a position of the arm and a presence of a card in the card infeed area. A method of shuffling cards is also disclosed. The method includes the steps of providing cards to be shuffled into a card infeed area as a stack with a top and bottom and removing cards one at a time from the bottom of the stack and moving the removed cards to a shuffling zone. Cards are then shuffled. The stack of cards is stabilized by a pivoting arm capable of pressing against the top of the stack in an engaged position. The pivot arm may be automatically rotated from a first card-engaging position to a second recessed position.
1. A card-feeding device for a card-handling device, comprising: a card infeed area comprising at least one feed roller at least partially defining a card support surface for supporting a stack of cards and at least two vertically-extending card support structures for containing the stack of cards,
1. A card-feeding device for a card-handling device, comprising: a card infeed area comprising at least one feed roller at least partially defining a card support surface for supporting a stack of cards and at least two vertically-extending card support structures for containing the stack of cards, a first structure of the two vertically-extending card support structures being positioned on a first side of the stack of cards and a second structure of the two vertically-extending card support structures being positioned on a second side of the stack of cards, the first structure, the second structure and the card support surface defining a volume therebetween for receiving the stack of cards, the at least one feed roller for removing cards individually from the bottom of the stack of cards; anda pivotable arm movable between a card-engaging position and a retracted position, the pivotable arm configured and positioned to press against an uppermost card in the stack of cards disposed in the card infeed area, the pivotable arm having a pivot point that is positioned between the card support surface and an upper portion of the card infeed area, wherein, in the card-engaging position, a portion of the pivotable arm is positioned within the card infeed area, and wherein, in retracted position, the pivotable arm is entirely removed from the card infeed area and the volume between the first structure, the second structure, and the card support surface. 2. The card-feeding device of claim 1, wherein the pivot point is vertically positioned at least 15 mm above the card support surface. 3. The card-feeding device of claim 1, wherein the pivot point is laterally spaced from the card infeed area. 4. The card-feeding device of claim 1, wherein the pivotable arm comprises: a contact end opposite the pivot point and configured to press against the uppermost card in the stack of cards; anda bridging length having a recess that is elevated above a line connecting a bottom of the contact end and the pivot point when the pivotable arm is in a card-engaging position. 5. The card-feeding device of claim 1, wherein the pivotable arm is biased into a card-engaging position. 6. The card-feeding device of claim 1, further comprising at least one sensor for detecting at least one of a position of the pivotable arm within the card-feeding device and a presence of a card in the card infeed area. 7. A card-shuffling system, comprising a card shuffler for randomizing at least one deck of cards; andthe card-feeding device of claim 1 for supplying cards to the card shuffler. 8. A method of feeding cards, the method comprising: placing a stack of cards into the card infeed area of the card-feeding device of claim 1;applying a force to an uppermost card of the stack of cards with the pivotable arm; andremoving cards one at a time from the bottom of the stack of the cards. 9. The method of claim 8, further comprising rotating a portion of a pivotable arm into contact with the uppermost card of the stack of cards with a motor to apply the force to the uppermost card. 10. The method of claim 8, further comprising contacting the uppermost card of the stack of cards with a wheel carried by the pivotable arm. 11. The method of claim 8, further comprising detecting the presence or absence of cards in the card infeed area with a sensor. 12. The method of claim 8, further comprising detecting at least one of a degree of rotation of the pivotable arm and pressure by the pivotable arm against playing cards in the infeed area with a sensor. 13. The method of claim 9, further comprising removing the pivotable arm from the card infeed area with the motor. 14. The method of claim 9, further comprising adjusting an amount of force applied to the uppermost card of the stack of cards by the pivotable arm with the motor. 15. The method of claim 10, further comprising positioning an upper portion of the stack of cards within a recess formed in the pivotable arm between the pivot point and the wheel. 16. A card-feeding device for a card-handling device, comprising: a card infeed area comprising at least one feed roller at least partially defining a card support surface for supporting a stack of cards, the at least one feed roller for removing cards individually from the bottom of the stack of cards;a pivotable arm configured and positioned to press against an uppermost card in the stack of cards disposed in the card infeed area, the pivotable arm having a pivot point that is positioned between the card support surface and an upper portion of the card infeed area; anda motor coupled to the pivotable arm to directly rotate the pivotable arm, the motor for rotating an end of the pivotable arm opposite the pivot point to force the end of the pivotable arm opposite the pivot point in a downward direction into contact with the uppermost card in the stack as cards are removed from the card infeed area. 17. The card-feeding device of claim 16, wherein the motor is configured to apply pressure against the uppermost card in the stack as cards are removed from the card infeed area by rotating the pivotable arm. 18. A card-feeding device for a card-handling device, comprising: a card infeed area configured to receive a group of cards, the card infeed area comprising at least two vertically-extending card support structures for containing the stack of cards, the at least two vertically-extending card support structures defining a volume therebetween for containing the group of cards;a card removal device with a card support surface capable of removing cards individually from a bottom of the group of cards positioned in the card infeed area; anda pivotable arm configured, in a first engaged position, to apply a downward force to the group of cards in the card infeed area with an end portion of the pivotable arm and, in a second position, to have the end portion of the pivotable arm removed from the volume defined between the at least two vertically-extending card support structures. 19. The card-feeding device of claim 18, wherein the card removal device comprises at least one feed roller for supporting the cards in the card infeed area and at least partially defining the card support surface. 20. The card-feeding device of claim 18, wherein the pivotable arm has a pivot point that is positioned between an upper portion of the card infeed area and the card removal device. 21. The card-feeding device of claim 20, wherein the pivot point is configured to be vertically positioned below an uppermost portion of the group of cards when the group of cards is received in the card infeed area.
