Abstract:
A blind slat controller with braking function for rotating and locating blind slats at a certain light obstruction angle. The blind slat controller includes and a base seat and a cord reel having a protruding push body. The push body serves to push a coiled spring to unbind or bind a hub section of the base seat, whereby the cord reel is permitted to rotate or is braked and prevented from rotating. When unbound, a slat control rod can be driven and rotated to control the rotational angle of the blind slats. After the blind slats are rotated to a predetermined light obstruction angle, the cord reel stops rotating. At this time, due to the coiled spring's own elasticity, the coiled spring is restored to again bind the hub section. Accordingly, the cord reel is prevented from rotating to locate the blind slats at the predetermined light obstruction angle.
