摘要

Improvements in the construction of information and/or signaling devices, characterized by the fact that inside a removable cabin, opened by its head to allow users to penetrate inside and are protected from the weather and provided with a tilting roof for facilitate access to advertising elements and lighting fixtures embedded inside their walls, there is mounted a desk that has a switch and two rollers operable by users, so that, when acting on the switch, it is placed working. A projection mechanism that projects, on a screen visible through the panel of the desk and duly protected, one or the other of the two halves in which a microfilm carrier of the informative data appears divided -for example, one half for street and the other half. Half for plane-, achieving the vertical and horizontal displacements of said microfilm, for the location in it of a specific datum, by means of the rotation of the aforementioned rollers that, through a transmission system, cause, in addition to the aforementioned movements of microfilm, other movements, in the same sense and synchronized with the former, of a luminous element that, located behind a large plane mounted equally inside the cabin and above the desk, projects a dart into it luminous that indicates a point coincident with the particular data located in the microfilm and projected on the screen.
