Playing card shuffler
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.
1. A card shuffler apparatus, comprising:
a horizontal card support surface configured to receive cards;
a positioner configured to move a group of cards oriented substantially perpendicular to the card support surface in a first direction and a second opposite direction, the first and second directions substantially parallel to the card support surface, the positioner configured to move to a plurality of positions relative to the card support surface; and
a card receiver configured to receive a single card from the card support surface after the positioner moves the group of cards to a position of the plurality of positions relative to the card support surface.
2. The card shuffler apparatus of claim 1 , wherein the card shuffler apparatus is configured to individually release cards from the card support surface in a randomized order and to sequentially pass the released cards into the card receiver in the randomized order.
3. The card shuffler apparatus of claim 1 , wherein the card support surface is configured to support cards in a substantially upstanding on-edge orientation.
4. The card shuffler apparatus of claim 1 , wherein the card support surface defines a card aperture extending through the card support surface.
5. The card shuffler apparatus of claim 4 , wherein the card aperture is adapted to allow passage therethrough of only one card at a time.
6. The card shuffler apparatus of claim 5 , wherein the positioner is adapted to randomly reposition cards relative to the card aperture.
7. The card shuffler apparatus of claim 1 , further comprising an exciter configured to impart vibration to the cards over the card support surface.
8. The card shuffler apparatus of claim 1 , further comprising a gate configured to move relative to the card support surface between a first position and a second position, wherein cards supported on the card support surface are prevented from moving to the card receiver by the gate when the gate is in the first position, and wherein a card supported on the card support surface is allowed to move to the card receiver when the gate is in the second position.
9. The card shuffler apparatus of claim 8 , further comprising an actuator configured to move the gate between the first position and the second position.
10. The card shuffler apparatus of claim 1 , wherein the card support surface at least partially defines a receptacle configured to receive cards from a user of the card shuffler apparatus.
11. A method of shuffling cards, comprising:
moving a first plurality of cards in a first direction substantially parallel to a card support surface to a first position relative to the card support surface, the card support surface having an aperture therethrough;
transferring a first card through the aperture in the card support surface to a card receiver to leave a second plurality of cards less than the first plurality of cards on the card support surface;
moving the second plurality of cards in a second direction opposite the first direction to a second position relative to the card support surface; and
transferring a second card through the aperture in the card support surface to the card receiver.
12. The method of claim 11 , wherein transferring a first card through the aperture in the card support surface comprises transferring only one card through the aperture in the card support surface, and wherein transferring a second card through the aperture in the card support surface comprises transferring only one card through the aperture in the card support surface.
13. The method of claim 11 , wherein moving a first plurality of cards in a first direction substantially parallel to a card support surface to a first position relative to the card support surface comprises moving the first plurality of cards to a first random position relative to the card support surface, and wherein moving the second plurality of cards in a second direction opposite the first direction to a second position relative to a card support surface comprises moving the second plurality of cards to a second random position relative to the card support surface.
14. The method of claim 11 , further comprising collecting cards played in a playing card game and placing the cards played in the playing card game over the card support surface to form the first plurality of cards.
15. The method of claim 11 , further comprising removing cards from the card receiver and using the cards removed from the card receiver in a playing card game.
16. The method of claim 11 , further comprising supporting the first plurality of cards and the second plurality of cards in an upstanding on-edge orientation over the card support surface.
17. The method of claim 11 , further comprising vibrating the first plurality of cards and the second plurality of cards.
18. The method of claim 17 , wherein vibrating the first plurality of cards and the second plurality of cards comprises vibrating the first plurality of cards and the second plurality of cards at a frequency in a range from about 10 Hz to about 100,000 Hz.
19. A card shuffler apparatus, comprising:
a receptacle in which a user of the card shuffler apparatus may place a plurality of cards in a substantially vertical orientation;
a positioning mechanism configured to randomly reposition the plurality of cards horizontally in two opposite directions in the receptacle;
a transfer mechanism configured to individually release cards responsive to gravity from the receptacle in a randomized order; and
a card collector for receiving cards individually released from the receptacle and from which the received cards may be removed from the card shuffler apparatus by the user of the card shuffler apparatus.
20. The card shuffler apparatus of claim 19 , further comprising an exciter configured to cause the plurality of cards in the receptacle to vibrate.
