However, in the conventional device described above, since the pair of winding shafts are always connected to each other, both ends of the display screen are moved between the winding rollers A and B while tension is applied to the tension spring. To wind the roll, first surround the take-up roller B with a roller several to several dozen times in the opposite direction to the winding rotation direction of the take-up shaft against the tension spring to bias the tension spring. While maintaining the same state, wrap one end of the display curtain around the other take-up roller A, and wrap the other end of the display screen, leaving an extra length between both take-up rollers A, around the circumferential surface of take-up roller B. It is very difficult to attach the display screen while holding the take-up roller B against the return force of the tensioning spring. In order to fix the end of the display curtain to the circumferential surface of the take-up roller while resisting, align the end of the display curtain with the circumferential surface of the take-up roller (in the longitudinal direction to align at right angles.
