Method and apparatus for card handling device calibration
First Claim
1. A method of calibrating a card handling device, comprising:
- using at least one component of the card handling device to count a number of cards being handled by the card handling device;
positioning the cards being handled by the card handling device in a stack on a card support surface of an elevator of the card handling device;
using at least one other component of the card handling device to detect a location of at least one of the card support surface and a top card in the stack within the card handling device; and
using the counted number of the cards and the detected location of the at least one of the card support surface and the top card in the stack to determine an average thickness of the cards being handled by the card handling device.

Abstract
A device for automatically calibrating for card size and thickness during card handling is disclosed. The device includes a card receiving area, a card stacking area and a card moving system for moving cards from the card receiving area to the card stacking area. An elevator located in the card stacking area has a movable platform for moving a stack of cards. At least one sensor senses at least one of position of the platform, height of the platform, position of a card in the elevator, height of a card or cards in the elevator, pressure applied to a card in the elevator, presence of the platform at a predetermined height, presence of the platform at a predetermined position, presence of card(s) on the platform, and absence of card(s) on the platform. A method for calibrating a card handling device during shuffling is also disclosed.

16. A self-calibrating card handling device, comprising:
-
an elevator having a card support surface thereon; at least one vertically stationary card gripper for gripping one or more cards to be positioned in a stack over the card support surface of the elevator; a microprocessor programmed to control operation of the elevator and the at least one vertically stationary card gripper; and memory for storing information to be processed by the microprocessor; wherein the microprocessor is programmed, using one or more additional components of the card handling device, to count cards to be handled by the card handling device and to be positioned in the stack, to detect a location of at least one of the card support surface and a top card in the stack over the card support surface, and to use a counted number of the cards and the detected location of at least one of the card support surface and the top card in the stack to determine an average thickness of the cards in the stack. - View Dependent Claims (17, 18, 19, 20)
