Card shuffling apparatus with automatic card size calibration during shuffling

摘要

A device for automatically calibrating for card size 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, and has a collection surface on the platform. A motor moves the platform within the elevator. At least one sensor senses at least one of a) position of the platform, b) height of the platform, c) position of a card in the elevator, d) height of a card or cards in the elevator, e) pressure applied to a card in the elevator, e) presence of the platform at a predetermined height, f) presence of the platform at a predetermined position, g) presence of card(s) on the platform, and h) absence of card(s) on the platform. A method for calibrating a card handling device during shuffling is also disclosed. The method is practiced by providing a device having a card receiving area and a card stacking area comprising an elevator with a card support platform and grippers. The method includes feeding at least two initial cards into a card stacking area, automatically identifying a target elevator height that corresponds to a height at which at least a single card on the card support platform is gripped and one card remains on the platform, and randomly feeding remaining cards into the card stacking area.
