  • Patent number: 4621814
    Abstract: A device useful in allowing two or more video gaming devices to be placed in a common cabinet, thus reducing floor space requirements and thereby improving profit yield per square foot in a gaming establishment or casino. Cabinet configuration includes mirror image cabinet halves, each of which includes a recess in which a game actuating handle may be located. The recess thereby eliminates the need for spacing of gaming device cabinets, when placed side by side. Mirror image configuration allows the games to be placed facing in any desired direction. Cooperation of a baffle and collar electromagnetically isolates a cathode ray tube (CRT) display in each gaming device one from the other to prevent display interference with and from the CRTs. Thus, the invention allows the placement of independent video displays in close proximity, preferably within a common cabinet.
