FIELD: construction. ^ SUBSTANCE: present invention pertains to advertisement and can be used for presenting different successively alternating information. The device has a frame, a driving mechanism and blocks. Each block has upper and lower monorails with a rectangular cross section and a rectangular shape. The monorails have two oppositely lying display sections and two storage sections. On the monorails there are moveable carriages. Posts with information elements are fixed to the carriages using holding pads. Information elements are made from flexible, elastic material with little expansion. The edges of information elements are fixed to vertical posts and are joined to posts of adjacent carriages. Flat-topped arms, joined to the frame, are fixed to the monorails. On the arms, there are stoppers with elastic members, and a through shaft. Two-sided levers with one-sided elastic carriers are fixed to the shaft. The levers are linked to the driven axle of the carriages and with chamfered ends, linking them to elastic members of the stoppers. According to the proposed method, posts with information elements in each block are synchronically moved in pairs on the monorails. The posts are drawn apart in the display plane, forming an information field and are scrolled in the storage sections, forming a loop. One pair of posts is drawn apart in one display plane, and the other - in the other display plane. The number of pairs of posts in each storage section is odd. ^ EFFECT: smaller size of the device, information elements and driving mechanism; provision for an even surface of the information field and easier replacement of display fields. ^ 3 cl, 8 dwg |
