PURPOSE:To enhance conveyability and visibility by arranging multiple light emitting elements on a surface of a foldable sign board to display specific characters or figures, and conducting lighting or blinking. CONSTITUTION:A pair of right and left bottom base boards 11 are connected to each other to be foldable to the outside by means of a hinge sheet 12, and a pair of sign boards 13 for constituting both small inclined surfaces are foldably connected respectively to ends of the bottom base boards 11. Reflection sheets 15 of, for example, arrow-shape for indicating directions are affixed on the boards 13, and also a plurality of light emitting elements for displaying characters of, for example, 'ACCIDENT' and the like are fitted thereto. Further, a control box 19 of the light emitting element is embedded via a lead wire 20 in the bottom base board 11 and connected to a switch contact piece 23 which is projected from the box 19 when the sign is used. |
