Abstract

An apparatus is for shuffling a plurality of playing cards used in gaming. The apparatus includes a card support adapted to support the unshuffled cards on-edge. An exciter is also included, and is adapted to impart vibrational action to the supported cards. Cards drop in a random fashion such as by controlling the relative position of the cards and passage through one or more card slots in a card rest. In at least some of the apparatuses, a medial card receiver is adapted to receive at least one card dropped from the card support and to retain the at least one received card to substantially block the card slot to prevent further cards from dropping. A positioner is preferably included to change a relative position of the unshuffled deck and card slots though which the cards drop.

means for moving cards individually released from the card support in a randomized order into the card collector in the randomized order;

wherein the card shuffler apparatus is configured to individually release cards in the single stack of cards from the card support in a randomized order, and to sequentially pass the released cards into the card collector in the randomized order; and

wherein the means for moving cards individually released from the card support in a randomized order into the card collector in the randomized order comprise one of a guide wheel having vanes, a jet pulser, and a link coupled to a solenoid.

9. A card shuffler apparatus, comprising:

a card support in which a single stack of cards to be shuffled may be directly placed by a user of the card shuffler apparatus;

a card collector for collecting cards released from the card support and from which shuffled cards may be removed from the card shuffler apparatus by a user of the card shuffler apparatus; and

a receiver that defines a card space adapted to temporarily receive cards released from the card support in a randomized order prior to their passage into the card collector in the randomized order;

wherein the card shuffler apparatus is configured to individually release cards in the single stack of cards from the card support in a randomized order, and to sequentially pass the released cards into the card collector in the randomized order.

10. The card shuffler apparatus of claim 9, wherein the receiver is adapted such that a card temporarily received within the receiver prevents release of any additional cards from the card support until the card temporarily received within the receiver is passed into the card collector.

11. A card shuffler apparatus, comprising:

a card support including a card aperture having a fixed width extending therethrough and a card support surface, the card support adapted to support cards to be shuffled in an upstanding on-edge orientation over the card support surface; and

a positioner adapted to provide lateral movement between cards to be shuffled and the card aperture;

wherein the card shuffler apparatus is configured to individually drop cards from the card support surface through the card aperture extending through the card support in a randomized order.

12. The card shuffler apparatus of claim 11, wherein the cards drop from the card support surface due to gravity alone.

13. The card shuffler apparatus of claim 11, wherein the card aperture is adapted to allow passage therethrough of only one card at a time.

14. The card shuffler apparatus of claim 13, wherein the positioner is adapted to randomly reposition cards to be shuffled on the card support surface relative to the card aperture.

16. The card shuffler apparatus of claim 11, wherein the positioner is adapted to randomly reposition cards to be shuffled on the card support surface.

17. The card shuffler apparatus of claim 11, wherein the card support at least partially defines a receptacle in which cards to be shuffled are directly placed by a user of the card shuffler apparatus.

18. The card shuffler apparatus of claim 17, further comprising a card collector for collecting cards dropped from the card support surface through the card aperture extending through the card support, and from which shuffled cards are removed from the card shuffler apparatus by a user of the card shuffler apparatus.

19. The card shuffler apparatus of claim 18, wherein the card shuffler apparatus is adapted to pass cards individually dropped from the card support surface sequentially into the card collector in a randomized order.

15. A card shuffler apparatus, comprising:

a card support having a card aperture extending therethrough and a card support surface, the card support adapted to support cards to be shuffled in an upstanding on-edge orientation over the card support surface; and

an exciter adapted to impart vibratory action to cards to be shuffled on the card support surface;

wherein the card shuffler apparatus is configured to individually drop cards from the card support surface through the card aperture extending through the card support in a randomized order.

20. A card shuffler apparatus, comprising:

a card support having a card aperture extending therethrough and a card support surface, the card support adapted to support cards to be shuffled in an upstanding on-edge orientation over the card support surface;

a positioner adapted to randomly reposition cards to be shuffled in the card support relative to the card aperture; and

a gate configured to move relative to the card support between a first position in which cards supported on the card support surface are prevented from passing through the card aperture by the gate and a second position in which a card supported on the card support surface is allowed to pass through the card aperture.

randomly moving the stack of unshuffled cards over the card aperture and individually passing cards from the stack of unshuffled cards through the card aperture and into a card collector in a randomized order.

26. The method of claim 25, further comprising collecting cards played in a playing card game and placing the cards played in the playing card game directly into a card support to form the stack of unshuffled cards over the card support surface.

27. The method of claim 25, further comprising removing cards from the card collector and using the cards removed from the card collector in a playing card game.
