Centrifugal card shuffler
View Patent ↗A card handling apparatus and method of manufacture and assembly is used for creating pre-formed hands for use in casino poker games whereupon the apparatus may be programmed to accommodate a number of different game variations, and a number of players is disclosed. The apparatus comprises an unshuffled card input portal, a shuffled card discharge portal and a radial card receiver whose operation utilizes centrifugal force. The exploitation of centrifugal force allows the apparatus to be operated without the need for the motorized pusher mechanisms which are prevalent in the prior art, thus creating a shuffler that is more compact and requires less manufacturing cost.
1. A card handing device for shuffling playing cards in a casino comprising:
a housing;
a control panel positioned on the exterior of the housing;
an unshuffled card input portal consisting of a single card receiving cavity;
a shuffled card discharge portal consisting of a single card discharge cavity;
a rotatable card receiver having a plurality of radially-arranged card storage nests which rotate about a common axis;
each nest having an exit orifice and an entrance orifice;
each nest holding a plurality of cards;
at least one microcontroller responsive to the control panel;
a motor that rotates the card receiver incrementally and bidirectionally amongst the radially arranged nests while producing centrifugal force;
a card transport that moves cards from the input portal to the rotatable card receiver in the direction of the centrifugal force;
at least one retainer that retains cards within the rotatable card receiver in opposition to centrifugal force;
card substacks within each nest being aligned by the retainer; and
wherein the card handing device moves cards into the nests and out of the nests in the same centrifugal force direction; and
wherein the card handing device moves the card substacks from the nests to the output portal by centrifugal force; and
wherein the card handing device has at least one direct path operable to convey individual cards directly from the input portal to the discharge portal.
2. The card handling device of claim 1 that signals an error condition upon card count deviation from a previously programmed parameter.
3. A card handing device for shuffling playing cards in a casino comprising:
a housing;
a control panel positioned on the exterior of the housing;
an unshuffled card input portal consisting of a single card receiving cavity;
a shuffled card discharge portal consisting of a single card discharge cavity;
a rotatable card receiver having a plurality of radially-arranged card storage nests;
the plurality of nests all rotating about a common axis;
each nest having an exit orifice and an entrance orifice;
each nest holding a plurality of cards;
at least one microcontroller responsive to the control panel;
a motor that rotates the card receiver incrementally and bidirectionally amongst the radially arranged nests while producing a centrifugal force;
a card transport that moves cards from the input portal to the rotatable card receiver in the direction of the centrifugal force;
at least one retainer that retains cards within the rotatable card receiver in opposition to centrifugal force;
card substacks within each nest being aligned by the retainer; and
wherein the card handing device moves cards into the nests and out of the nests in the same centrifugal force direction; and
wherein the card handing device moves the card substacks from the nests to the output portal solely by gravity; and
wherein the card handing device has at least one direct path operable to convey individual cards directly from the input portal to the discharge portal.
4. The card handling device of claim 3 that signals an error condition upon card count deviation from a previously programmed parameter.
