<p>The poster display equipment is multi directional and has several panels which are turned successively in all directions. It has a fixed support structure (1) with drive mechanisms (3,4,5,6) and a mobile loader (11) for stocking posters. There is also a movable outer structure (16) for poster windows. The loader-stocker is driven in alternate translation movements and simultaneous rotation. This permits pressing of the charger inlet and outlet on each successive window to withdraw and place posters, the movements all being synchronised. The drive is done by four thin plates forming a Maltese cross arrangement (21).</p> |
