[0012] Deficiencies in shuffler operation, including card jams can be electrically or electronically identified. Various physical events such as angular speed or linear speed of shuffler components (e.g., shafts, rollers, pushers, grips, elevators, etc.) can be determined in absolute or relative term...

Embodiment Construction
[0024] In normal operation of a shuffling device, there are moving parts that operate to receive, move, orient, load, unload, insert, raise, or lower a single card, group of cards, or complete sets (e.g., decks) of cards. There are a number of reasons why these moving parts may change their quality of movement during a shuffling procedure. In addition to normal wear and deterioration of components, card jams can occur, even with the best designed and engineered products. As significant portions of the shuffling process and the shuffling operation may be hidden from view, there is not necessarily any visual indication that shuffling is not properly proceeding. Waiting until well past an expected end of the shuffling process to find that cards or hands of cards are not being delivered is both an inefficient way of determining shuffling status, and could lead to damage of the equipment if a non-functional shuffling process is stressing parts and components in the shuffler. In addition,...

Abstract
A shuffling device for playing cards and method of shuffling cards is provided where a first group of cards is moved within the device to form a randomized second group of cards. The device comprises moving parts that assist in the movement of cards within the shuffling device; a processor in informational connection with the shuffling device; a sensor which detects at least one of speed, distance and force of at least one moving part and provides a signal to the processor regarding detection of at least one of speed, distance and force; and the processor containing a program that interprets the signal to detect significant variations in at least one of speed, distance and force of the moving part.
Description
BACKGROUND OF THE ART [0001] 1. Field of the invention [0002] The present invention relates to card shufflers, particularly playing card shufflers, and the detection of jamming or erroneous mechanical performance in the operation of the shuffler. [0003] 2. Background of the Art [0004] Examples of shuffling devices for playing cards, particularly for use in casinos are described in U.S. Pat. Nos. 4,659,082; 6,659,460; 6,655,684; 6,651,982; 6,651,981; 6,588,751; 6,588,750; 6,568,678; 6,325,373; 6,267,248; 6,254,096; 6,149,154; 6,139,014; 6,068,258; 5,989,122; 5,695,189; 5,676,372; 5,584,483; 5,382,024; 4,832,342; 4,659,082; and 4,586,712. In these known shuffling apparatuses, various different formats of randomizing cards are performed. In U.S. Pat. No. 4,659,082, the shuffling vessel is formed by a horizontally arranged drivable drum that is provided with radially extending shafts for receiving a card each. An input station for receiving a stack of discarded playing cards is provided...
