Embodiment

Fig. 1 shows a circular configuration 2, and this circular configuration 2 has three display device 102 that are used for showing three placard bars 3 on its circumference, and for instance, this circular configuration 2 can be the Mo Lisi post.Each placard bar 3 is installed in and is marked as on the whole on 4 the framework.Two

vertical axles

8,9 that have power are installed on this framework, on described Z-

axis

8,9, are wound with the end of placard bar 3.The length of a placard equal to be parallel to cylindrical outside surface and apart from this outside surface distance length of one section short circular arc.The back side of framework 4 promptly between the Z-

axis

8 and 9, is provided with display device 12, and described display device 12 comprises fluorescent tube 13.

In more detail, as shown in Figure 2, each display device 102 comprises crooked leading flank 106 and supporter 107, and described supporter 107 comprises rear wall 108 and antetheca 109, described rear wall 110 and antetheca 109 are transparent or translucent, and limit an inner space or chamber 110 jointly.Chamber 110 is sealed by a frame part 114 around its circumference.Fan 111 has one and is connected to the sprocket hole of inner space 110 by opening 112, and described opening 112 is formed on the position at the center that is approximately rear wall 108.Antetheca 109 is provided with a plurality of holes 113, and described hole 113 limits perforation pattern.

In addition, as shown in Figure 3, display device 102 is provided with the system that is used to support placard bar 3: this system comprises that guide rail 130, the first balladeur trains 131 and second balladeur train 132 can move along this guide rail 130.In the

balladeur train

131 and 132 each all has the sucker 133 by electromagnet 134 operations, so that the placard bar is pressed to back up pad 135.The quantity that should be noted that balladeur train 131 and 132 is not restricted to two, but according to the quantity decision of the placard that shows on the placard bar 3, and

balladeur train

131 and 132 quantity equal the quantity of the initial placard of hiding.For example, if the placard bar comprise three placards and do not have boot segment, then need two balladeur trains.

When driving

shaft

8 and 9 rotated, fan 111 was unlocked, and made that the pressure in the chamber 110 increase, with and make air overflow from the hole 113 that is arranged on the antetheca 109.Air forms a mattress of pushing the surface of the antetheca 109 between supporter 107 and placard bar 3 by overflowing of perforation pattern, thereby avoids the placard bar attached on the supporter 107.Thereby the antetheca 109 of fan 111 and perforation has constituted the guiding parts of placard bar 3.When placard bar 3 is reeled, for example from twining axle 8 when twining axle 9 coilings, the electromagnet 134 of first balladeur train 131 applies voltage by an Electronic Control card (not shown), makes sucker 133 hold placard bar 3 in the position that is approximately the seam between first placard and second placard.Subsequently, balladeur train 131 moves and supports always the placard bar along with the placard bar, arrives the close position that twines axle 8 up to the placard bar, on this close position, removes the voltage of electromagnet 134, makes sucker 133 discharge placard bar 3.Said process also is applicable to second balladeur train that is designed to support at the seam crossing of the second and the 3rd placard placard bar 3.When twining
