Mechanical digital display

A mechanical digital display having at least one digit consisting of at least seven segments (1) for displaying alphanumeric characters, each segment (1) being a body in the form of a bar (1) which can pivot on its longitudinal shaft (3), each of the said bars (1) having at least two areas resembling a first and a second strip (1′, 1″) having different appearances, the said strips (1′, 1″) being arranged along the length of the bar (1) in such a way that the orientation of the bar (1) by a rotation about its longitudinal shaft (3) enables either the first or the second strip (1′, 1″) to be made visible, the display of an alphanumeric character being achieved as a result of the dissimilarity of appearance between the first and the second strip (1, 1″) of the set of bars (1), the pivoting of one or more bars (1) to replace the first strip (1′) with the second strip (1″) or vice versa generating the display of different alphanumeric characters, characterized in that at least one pinion (2), fixed to the bar (1), is positioned around each longitudinal shaft (3) adjacent to at least one of the ends of said bar (1), the bars (1) being pivoted by means of cams (4) interacting directly or indirectly with each pinion (2), characterized in that the mechanical digital display comprises an operating device designed to transmit a rotary movement to said cams (4) by pulses so that the pivoting of the bars (1) takes place instantaneously or virtually instantaneously.
