This place does not cover:

Score computers for card games

Construction of keys, printing mechanisms or other parts of general application to the typewriting or printing art

Computing mechanisms where the output is observed on a scale, like slide rules, are considered analogue computing arrangements

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

Cash registers

Special rules of classification

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
