  • Patent number: 4863173
    Abstract: All of the number matrices of every bingo card (of the available cards) of a bingo-chain game device are stored in a microprocessor/storage unit. A display dot matrix is connected to the microprocessor/storage unit to identify the numbers selected by a player. A keyboard is connected to the microprocessor/storage unit so that the player can input every called number into the storage of the microprocessor/storage unit. A plurality of transparent bingo cards, with preset codes along one side thereof, is automatically read by a signal reading unit which also retrieves pre-stored data from the storage of the microprocessor/storage unit. The data on the transparent cards are stored into the storage of the microprocessor/storage unit. The signals on the transparent bingo cards can also be represented by bar codes. Data code and clock code on a single side of a transparent bingo card are read by the signal reading unit and can be pre-stored in the microprocessor/storage unit.
