The posters or announcements (2,3) can be fed forward successively, each being divided into a number of strips (1,b,c; 1',b(,c') mounted on a carrier (4,5) by band-type holders (15,16,17;15',16',17'), so that the different stips can be pivoted outwards from their carrier like flaps, and inserted between two stripss of the preceding posters or announcements. By raising and lowering the carrier, the required strips (a,b,c) are located in a foremost position, i.e. that for viewing, and form a visible motif. Appts. (10,21-26) is provided to press the strips against a transparent sheet (1) so that those nearest to the sheet are located in the viewing position, being pressed into a position in one and the same plane. Each strip is fitted in its own plastic pocket. An electric motor (11) turns a shaft with cam plates (12,13,14) fitted on it for selective raising and lowering of the carrier. |
