Transmission control structure for curtain system

A transmission control structure for a curtain system, wherein the curtain system has an upper transverse track, a rope is disposed on the upper transverse track, the rope can move at least one curtain, disposed below the upper transverse track, to be developed or retracted, and the characteristic lies in that:

• the transmission control structure comprising a transmission set and a driving set is disposed on one end portion of the upper transverse track;
• the transmission set has a base casing, wherein one end of the base casing is formed with a mounting portion, on which the end portion of the upper transverse track is mounted, and a pulley to be wrapped around by the rope is pivotally mounted in the base casing;
• and
• the driving set may be disposed on the transmission set, a motor with controllable forward and reverse rotations and a controllable rotating speed is disposed in the driving set, and the motor has an output shaft capable of synchronously driving the pulley of the transmission set.
