DIGITAL COMPUTERS IN WHICH ALL THE COMPUTATION IS EFFECTED MECHANICALLY
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
B41
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
This subclass/group does not cover:
Arrangements for table look-up comprising also computing elements manipulated by hand
Informative references
Attention is drawn to the following places, which may be of interest for search:
Appliances for teaching counting or calculating
Indicating or scoring devices for games or players
Models for scientific, medical, or mathematical purposes
Rosaries
Arrangements for table look-up, e.g. menstruation table
Informative references
Attention is drawn to the following places, which may be of interest for search:
Ovulation period determination in humans
Ovulation period determination in animals
Non-functional elements
Input mechanisms
References relevant to classification in this group

Storage mechanisms
Informative references
Attention is drawn to the following places, which may be of interest for search:
Information storage in general
G11
Mechanical counters with input only to the lowest order
Computing mechanisms; Actuating devices therefor
References relevant to classification in this group
This subclass/group does not cover:

Mechanisms for converting from one notational system to another, i.e. radix conversion
Decimal-point mechanisms; Analogous mechanisms for non-decimal notations
Programming mechanisms for determining steps to be performed by the computing machine, e.g. when a key or certain keys are depressed
References relevant to classification in this group
This subclass/group does not cover:
Mechanisms merely for producing multiplication by repeated addition
Driving mechanisms for functional elements
Special rules of classification within this group

G06C 23/08 takes precedence over G06C 23/02 to G06C 23/06

Auxiliary functional arrangements, e.g. interlocks
References relevant to classification in this group
This subclass/group does not cover:
Interlocks in keyboards
Computing machines characterized by the structural interrelation of their functional units, e.g. invoicing machines
Combinations of computing machines with other machines, e.g. with typewriter, with money-changing apparatus
