Card shuffler
First Claim
1. A method for performing an inventory of cards in an electronically controlled card shuffler, with cards of an unshuffled stack being output to an output stage in a random sequence, the method comprising:
- forwarding cards from the unshuffled stack into individual compartments of the card shuffler;
detecting the passage of each card forwarded to the compartments;
counting the number of cards forwarded to the compartments to determine the number of cards within each of the compartments;
ejecting cards from the compartments into the output stage; and
subtracting the number of cards ejected from the compartments from the number of cards forwarded to the compartments to identify the total number of cards still in the compartments, wherein subtracting the number of cards ejected from the compartments comprises subtracting the number of cards ejected from a compartment as a single group from the number of cards forwarded to the compartments, wherein detecting the number of cards ejected from the compartments comprises detecting actuation of an ejecting device that ejects all cards from a compartment as a group.

Abstract
A card shuffler with a drivable shuffling storage means (2′) which is provided with compartments (69) for receiving cards (13) and which is associated with an input apparatus for inserting cards into the compartments (69) one by one and an output storage means which is spaced from the same for the shuffled cards, with the drive of the shuffling storage means (2′), the input apparatus and the output storage means being controlled by an electronic control system. In order to provide a card shuffler of the kind mentioned above which is capable of continually displaying the number of playing cards situated in the card shuffler and thus of providing the operator with the opportunity to have at all times certainty about the complete number of playing cards it is provided that the input apparatus (106) is provided with a draw-in zone (105) whose height corresponds substantially to the thickness of a card (13) and a first detection means (24) and a second detection means is provided which detects the cards (13) inserted into and removed from the shuffling storage means.

12. An electronically controlled card shuffler comprising:
-
an input stage for receiving an unshuffled stack of cards;
a movable storage device having compartments for receiving cards;
a transporter for forwarding cards, one at a time, from the unshuffled stack to the compartments;
an ejector for ejecting cards from the compartments into an output stage such that a sequence of cards entering the compartments is different from a sequence of cards delivered to the output stage; and
a detector for detecting the passage of each card forwarded to the compartments, detecting a number of cards ejected into the output stage, and determining the total number of cards still in the compartments, wherein the ejector ejects all cards from a compartment as a single group, the detector further detecting the number of cards within each of the compartments and subtracting the number of cards ejected from the compartments as a single group from the number of cards forwarded to the compartments, wherein the detector comprises a sensor for detecting actuation of the ejector that ejects all cards from a compartment as a group. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
