Abstract: Proposed is a roller blind drive device preventing an accident due to a drive cord, the drive device being configured to lower or raise a curtain fabric by performing forward/reverse rotation of a drum on which the curtain fabric is wound, the drive device including a fixed part, a rotating part mounted rotatably to the fixed part and configured to perform the forward/reverse rotation of the drum, a circular drive cord having a front cord and a rear cord, and a manipulating part connected to the drive cord exposed to the lower side of the fixed part. Accordingly, the drive cord is covered so as not to be seen from the outside, and any one drive cord of the two drive cords is held by the rotating manipulation of the manipulation tube.
