Dart game score board

1. A system for manually inputting and keeping the scores of one or two players playing the various games of darts, said system consisting essentially of:

a case,

said case having a central display, the central display consisting of two separate means, one for each two players, for displaying each player's dart hit in each corresponding pie-shaped region of a dart board, the dart hit displaying means for each corresponding pie-shaped region of the dart board including one button for activating a single “slash” symbol display on a lighted window representing one hit in the pie-shaped region, a separate button for activating an “X-shaped” symbol displayed on the lighted window representing two hits in the pie-shaped region, and another separate button for activating a “O-shaped” symbol displayed on the lighted window representing three hits in the pie-shaped region,

said central display further consisting of cancel button means for each corresponding pie-shaped region of the dart board, for canceling a previously recorded hit,

two keypads, each associated with a respective four digit display for displaying dart game scores for each player, the keys of each keypad including an individual key for starting a new game, at least three individual keys for playing a game at a predetermined point level, an individual key for recalling a previous entry, a clearing key, a key for each number 0–9, a plus sign key and a minus sign key,

electronic circuitry means for connecting and controlling said central display and keypads, and

said circuitry means being programmed for activation and scoring a plurality of dart score games, providing control over input errors, allowing scorekeepers to recall previous scores, and making other corrections in the score displays.

2. The system according to claim 1 , wherein:

each keypad consists of a four column by five row cross point matrix configuration for generating a numeric value/function command,

said electronic circuitry means having a microprocessor,

said microprocessor comprises processing firmware, a read only memory, programmed to contain the instructions in the source code list, and a microprocessor data/command input-output generator and computational device, and

each of said four digit display consisting of a seven segment display using light diode arrays which are separate elements arranged in a straight line figure eight for displaying the desired numeric values 0–9.

3. A system for manually inputting and keeping the scores of one or two players playing the various games of darts, said system consisting essentially of:

a case,

said case having a central display, the central display consisting of two separate means, one for each two players, for displaying each player's dart hit in each corresponding pie-shaped region of a dart board, the dart bit displaying means for each corresponding pie-shaped region of the dart board including one button for activating a single “slash” symbol display on a lighted window representing one hit in the pie-shaped region, a separate button for activating an “X-shaped” symbol displayed on the lighted window representing two hits in the pie-shaped region, and another separate button for activating a “O-shaped” symbol displayed on the lighted window representing three hits in the pie-shaped region,

said central display further consisting of cancel button means for each corresponding pie-shaped region of the dart board, for canceling a previously recorded hit,
