Amendment August 6, 1982 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] A linkage mechanism is installed inside the guide rails located on both sides of the slat, and multiple stages of slats are supported on the linkage mechanism at equal intervals on the upper and lower sides. Raise and lower the slats
In the shutter, a drive shaft 4 is rotatably supported at the upper end of the guide rail 2, the drive shaft is rotatably driven by a drive means 5, a sprocket 9 is rotatably supported on the drive shaft, and one end is rotatably supported. a drive belt 13 connected to the linkage mechanism;
is hung on a sprocket so that the linkage mechanism can be driven to expand and contract based on the rotation of the sprocket, and the sprocket and the drive shaft are connected by a torsion coil spring 10 that expands and contracts in the rotational direction of the drive shaft. Shutter.

Claims (1)

[Scope of utility model registration request] A linkage mechanism is installed inside the guide rails located on both sides of the slats, and multiple stages of slats are supported vertically by the linkage mechanism at equal intervals, and each slat is moved up and down and rotated based on the expansion and contraction of the linkage mechanism. In a shutter configured to be opened and closed, a drive shaft 4 is rotatably supported at the upper end of a guide rail 2, the drive shaft is rotatably driven by a drive means 5, a sprocket 9 is rotatably supported on the drive shaft, A drive belt 13 whose one end is connected to the linkage mechanism is hung around the sprocket so that the linkage mechanism can be driven to expand and contract based on the rotation of the sprocket, and a torsion coil spring that expands and contracts between the sprocket and the drive shaft in the direction of rotation of the drive shaft. 10
