Abstract:
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.
