Abstract
A roller-shade winding roman style shade is provided. A technical feature thereof is to utilize an actuating member of a cord or a band-shaped long strip of fabric to connect a blind material and a roller shade. Thus, as the roller shade rises, the parts where the blind material and the actuating member are connected are pulled up sequentially from the bottom up, and when reaching the top end, the points where the blind material and the actuating member are connected are kept at approximately the same height, such that the roman style shade is in a retracted and folded state. The blind material of the whole roman style shade can be folded up or dropped down merely through connection of the actuating member between the blind material and the roller shade, the roller shade has diversified applications and is more flexible in use and pleasant to look at.
