A take-up device for a curtain includes a pull-cord, a reel mounted to a top beam of the curtain, an actuating mechanism for actuating the reel to rotate to retract or release the pull-cord, and a braking mechanism for braking the pull-cord. The reel defines a winding groove and an actuating slot. The actuating mechanism is a flat spiral-spring assembly. The flat spiral spring assembly includes a wheel arranged in parallel with the reel and a flat spiral-spring. An end of a reed of the flat spiral-spring is wrapped around the wheel, and an opposite end of the reed is fixed in the actuating slot. The top end of the pull-cord is wound on the winding groove, and an opposite end of the pull-cord extends out of the winding groove, extends through the braking mechanism, and then is fixed to a curtain body of the curtain.
