G06C DIGITAL COMPUTERS IN WHICH ALL THE COMPUTATION IS EFFECTED MECHANICALLY (score computers for card games A63F1/18)
Introduced: September 1968
Description
G06C covers purely mechanical digital computing machines where all arithmetic and logical operations are performed through mechanical means—such as gears, cams, levers, and linkages—without electronic components. This classification encompasses mechanical calculators, difference engines, and analogous electromechanical devices designed before the advent of electronics-based computing. Inventions in this class focus on mechanical mechanisms for implementing addition, subtraction, multiplication, division, and data storage or display through physical movement and mechanical logic.
