PURPOSE: A slotter screen is provided to prevent noise and to be used as a shutter and a screen for intercepting sunlight. CONSTITUTION: A slotter screen(8) is aluminum extrusion form material having each hinge(A,B) at both ends. The hinges(A,B) have each opening(9,10) on each slotter. The openings(9,10) contain an 'S' shaped-curved-outer circumference(S1,S2). And tangent line lengthened part of one side of a peg(1a) of the 'S' shaped curved face(S1) of the hinge(A) constitutes a straight line(3a), a recessed curved face(4a) is contacted at a flat sill(5a) contacted to the outer circumference of the slotter by contacting a circular arc(4a) of the recessed face of a radius focusing on a center point(10) of the peg(1a) of the curved face. And the slotter(8) maintains a plane of the straight line continuously by supporting so the contacted slotters as to be coupled by a compression stress by combining the recess(1b) and the peg(1a) of the hinge(A,B) expanded horizontally in a winding state.
