alphanumeric display with the aid of segments and subsegments.

摘要

1. Device comprising moving supports carrying a matrix of motifs (3) for allowing various information to be public displayed the device comprising elements (21) constituted by vertical segments or horizontal segments, characterized in that each segment (22) is subdivided into subsegments (8) constituted by at least two coaxial profiled pieces (1, 2) for alphanumeric display, the mechanism for rotating the subsegments (8) being entirely electro-mechanical, and in that a motor (23) is associated to a group of display elements through the intermediary of a transmission shaft (24) which, at the lower end of each one of these elements, transmits to two belts (17), through driving band (25), a translational movement which is used, for short periods, for operating racks (9) vertically guided in a rail (1) and mecanically arrested by electromagnets (15) during their displacement, the distance of the displacement of the rack being a function of the desired angle of rotation for the subsegments, which angle is determined by the number of motifs.
