<p>Improvements to viewers used in recreational machines, in which the figures are arranged along a continuous band (5), and based on the fact that said band (5) is supported and guided by a chassis in the form of a pair of parallel plates (1) and (2), joined by spacers (3), with the particular characteristic that each of the opposing faces of said plates are provided with a groove (4) designed to receive the corresponding edge of the continuous band (5) with play, acting as a means of guiding said band. Said grooves (4) undergo a sharp inflection along of one of the minor sides thereof, defining a kind of loop (6) where the continuous band (5) is driven by the corresponding pulling drum (8). This special system for guiding the continuous band (5) enables the grooves (4) to define a straight section (4') and a curved section (4''), converting the viewer into a reversible element which can present either a flat or a convex curved working area by simply inverting its position in the assembly. <IMAGE></p> |
