Abstract (en)
The invention concerns a device for the formation and replacement of messages in advertising or informative display panels with multiple message, provided with number of prisms (10;22) side by side and controllably rotatable, which carry on each face (12) a portion of a message formed in its entirety by all the portions of message positioned on the faces of the prisms having the same orientation. In order to make the message replacement easier, each face (12) of each prism (10; 22) is provided with one or more holding magnets (13, 14; 21, 24) and the relevant portion of message is prearranged on a foil (15) of ferromagnetic material, that can be removably fastened to the prism face by means of said holding magnets. <IMAGE>
