DIGITAL COMPUTERS IN WHICH ALL THE COMPUTATION IS EFFECTED MECHANICALLY (score computers for card games A63F 1/18; construction of keys, printing mechanisms or other parts of general application to the typewriting or printing art B41; keys or printing mechanisms for special applications, see the relevant subclasses, e.g. G05G, G06K; cash registers G07G 1/00)
References relevant to classification in this subclass
This subclass/group does not cover:
Cash registers
Computing mechanisms where the output is observed on a scale, like slide rules, are considered analogue computing arrangements
Construction of keys, printing mechanisms or other parts of general application to the typewriting or printing art
Details of mechanisms covered by main groups G06C 9/00, G06C 11/00, G06C 15/00 which are applicable to mechanical counters driven only through the lowest denomination
Score computers for card games
Special rules of classification within this subclass

G06C 3/00 takes precedence over G06C 1/00

Computing aids in which the computing members form at least part of the displayed result and manipulated directly by hand, e.g. abacus, pocket adding device
References relevant to classification in this subclass
