Structura mecanismului
Funcţie	This manual lever machine is of the Odhner type, i.e. with pinwheels containing a varying number of teeth. It has a capacity of 10 figures on the input register, 8 figures on the counter and 13 figures on the totalizer. On the rounded part, 9 levers (cursors) slide in grooves graduated from 0 to 9; they enable the input of the numbers to be calculated. The crank handle rotates the Odhner mechanism to which the levers are fixed, in one direction for addition and multiplication (by repeated additions) and in the other for subtraction and division. The lower part contains the mobile carriage with the manual advance. The various levers situated on each side enable the counters to be re-set.
