A window blind system including a headrail, a bottomrail, a covering material disposed between the headrail and the bottomrail, and a control device is provided. The control device controls collection and expansion of the covering material effectively. The control device comprises a case having a first shaft and a second shaft, a coil spring, a first wheel configured with a fixing hole, a second wheel engaged with the first wheel, a torsion spring configured with a fixing end. The torsion spring is sleeved around the first shaft. The first wheel and the second wheel are pivoted in the first shaft and the second shaft. The torsion spring is disposed between the first shaft and the first wheel. The fixing end of the torsion spring is fixed in the fixing hole of the first wheel. The coil spring is winded between the first wheel and the second wheel.
