On the front side 8a, for example, a long train is drawn over the entire length of the curtain 8, and on the back side 8b, various scenery are drawn continuously over the entire length of the curtain. Then, as shown in FIG.
7d, and from the state where one winding shaft 4 is wound around this for supply, the winding side rotating shaft 3 is driven to rotate at a required speed by the motor M (the rotating shaft 2 is left free). ), the display screen 8 travels in the direction shown by the arrow in FIG. A train is displayed on the display screen section 9 on the left, and a scenery is displayed on the display screen section 10 on the right, and the train and the scenery move away from each other, so that the scenery visible from the train window changes continuously. The appearance of being distracted begins to appear. In addition, on the rear side of the device, trains are displayed on the left display screen section 11 and scenery is displayed on the right display screen section 12 while moving in a direction approaching each other. Different display effects can be obtained.
When the winding of the display curtain 8 onto the winding shaft 5 on the winding side is completed, the winding shaft 3 on the winding side is set free and the other rotating shaft 2 is driven by the motor M. is rotated in the winding direction, and then the movement of the display curtain 8 is opposite to that in the above case.

In the usage example described above, an example was explained in which the display curtain 8 is moved continuously, but information is displayed in one frame (scene) each on the front surface 8a and back surface 8b of the display curtain 8, Each display screen portion may be moved intermittently for a predetermined period of time or while being stopped for an arbitrary period of time. In this case, the length of each frame corresponds to, for example, the length between guide rollers 6a and 6b, and the length between each frame corresponds to, for example, the length between guide rollers 6b and 6b.
