Claims

[Claims for Utility Model Registration] 1. In a blind that raises and lowers a slat by spirally winding a lifting cord with a winding pulley that moves in the longitudinal direction of the head box while rotating within the head box, 6a
, 6b winding position is located closer to the center in the longitudinal direction of the head box than the position where the lifting cords 6a, 6b are introduced into the head box 2. 2 The lifting cords 6a and 6b are connected to guide recesses 2 provided on both sides of the bottom of the main case 17 that supports the take-up pulley 8.
A space S formed by 6 and the 2 corners of the head box
2. A blind slat elevating device according to claim 1, wherein the slat is guided to the winding position through the slat. 3 The tip of the guide recess 26 is connected to the lifting cords 6a, 6.
b is branched into a first lead-out part 26a that guides the take-up pulley 8 outside the main body case 17 and a second lead-out part 26b that guides the wind-up pulley 8 inside the main body case 17. 2. The blind slat lifting device according to 2.
