This invention refers to a Sequential Multiposter Exhibitor, similar in appearance to another models, but that improve to these in the following aspects: Lower manufacturing price; reliability; ease of maintenance; and their optimization of proportions, that is, the relationship between the poster shown area and the dimensions of the exhibitor case. Their principal novelty resides, in that the spools (11) (figs. 1a and 1b) between those flows a flexible support-band (50) in which the posters are fixed, has coupled directly to a tangencial type gearbox-motoreductors (30), as well as in the procedure employed in order to permit that both motoreductors shafts; due their irreversibility characteristic; can turn to the appropiate speed to their respective instantaneous winding diameter, maintaining tense the support-band either during the displacement and the show pauses.
