The image screen 109 is arranged behind the signboard surface in nearly parallel to the signboard, the belt-like sheet of the scrolling signboard is partly formed of a transparent sheet. In the case of feeding the transparent sheet to the signboard surface of the scrolling signboard, a control to turn off the back light lamps 111 for the scrolling signboard and turn on the light source of the image screen is performed.
