Abstract
One or more illumination panels () are hung by up-and-down cords (). The up-and-down cords () have a function of hanging the illumination panels () and a function of supplying electric power to the illumination panels (). Pulling a rod (), which is a take-up tool causes the up-and-down cords () to be taken up and, at the same time, the bottom rail () and the illumination panels () are also raised. At this time, the up-and-down cords () are taken up into the head box (). As such, when the bottom rail () is raised, the up-and-down cords () are taken up without bending. This makes it possible to distribute stress that may otherwise be concentrated locally on the up-and-down cords (). As a result, the up-and-down cords () can be prevented from getting broken due to deterioration caused by concentration of stress on the up-and-down cords (), which concentration is caused by bending etc. of the up-and-down cords ().
