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:
at least one card supporter configured to receive and retain cards in a vertical orientation, the at least one card supporter having a first portion and a second portion, wherein an aperture extends through the at least one card supporter between the first portion and the second portion, wherein the aperture is configured to allow cards to pass therethrough;
a positioner configured to move the cards received and retained by the at least one card supporter horizontally to any selected position of a plurality of positions relative to the card aperture; and
a card receiver located to receive a single card through the card aperture after the positioner moves the cards to a selected position of the plurality of positions relative to the card aperture.
2. The card shuffler apparatus of claim 1 , wherein the card shuffler apparatus is configured to individually release cards through the card aperture 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 , further comprising:
a sensor located and configured to detect cards retained by the at least one card supporter;
an actuator coupled to the positioner and configured to move the positioner; and
a controller operably coupled to the sensor and configured to send a control signal to the actuator based on a status signal.
4. The card shuffler apparatus of claim 1 , wherein the at least one card supporter defines the card aperture.
5. The card shuffler apparatus of claim 1 , wherein the card aperture is adapted to allow passage therethrough of only one card at a time.
6. The card shuffler apparatus of claim 1 , 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.
8. The card shuffler apparatus of claim 1 , further comprising a gate configured to move relative to the at least one card supporter between a first position and a second position, wherein cards supported on the at least one card supporter are prevented from moving through the aperture to the card receiver by the gate when the gate is in the first position, and wherein a card supported on the at least one card supporter is allowed to move through the aperture 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 at least one card supporter 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 horizontally to a first position relative to a card aperture, the card aperture extending through a card supporter having a first portion and a second portion, the card aperture between the first portion and the second portion;
transferring a first card through the aperture to a card receiver;
moving a second plurality of cards horizontally to a second position relative to the card aperture, the second plurality of cards comprising fewer cards than the first plurality of cards; and
transferring a second card through the aperture to the card receiver.
12. The method of claim 11 , wherein transferring a first card through the aperture comprises transferring only one card through the aperture, and wherein transferring a second card through the aperture comprises transferring only one card through the aperture.
13. The method of claim 11 , wherein moving a first plurality of cards horizontally to a first position relative to the card aperture comprises moving the first plurality of cards to a first random position relative to the card aperture, and wherein moving the second plurality of cards horizontally to a second position relative to the card aperture comprises moving the second plurality of cards to a second random position relative to the card aperture.
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 aperture 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 generating random numbers and selecting each of the first position and the second position based on one of the random numbers.
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 configured to receive a plurality of cards to be shuffled in a substantially vertical orientation;
a positioning mechanism configured to randomly reposition the plurality of cards horizontally in the receptacle;
a transfer mechanism configured to release only one card at a time responsive to gravity from the receptacle in a randomized order; and
a card collector for receiving cards released from the receptacle.
20. The card shuffler apparatus of claim 19 , further comprising an exciter configured to cause the plurality of cards in the receptacle to vibrate.
21. The card shuffler apparatus of claim 19 , further comprising:
a sensor located and configured to detect cards retained by the receptacle;
an actuator coupled to the positioning mechanism and configured to move the positioning mechanism; and
a controller configured to send a control signal to the actuator based on a signal received from the sensor.
