BLIND DRIVING DEVICE
A blind driving device includes two cord winding and unwinding mechanisms each including bases, reels rotatably mounted to the bases, cords, and a power component. Each reel is a conical cylinder whose diameter gradually decreases from one end to the other end. Each base forms a first cord guide on a position corresponding to a great diameter end of the reel. One end of the cord is fixed to a small diameter end of the reel, while the other end of the cord is led out from the great diameter end after being wound along the reel and extends to be connected to a blind body after extending about the first cord guide. The reels of the two mechanisms are arranged in parallel in an axial direction, with the great diameter ends facing opposite to each other, or are arranged in parallel in the axial direction and are misaligned.
