PROBLEM TO BE SOLVED: To make usable plural screens as a continuous screen without being interrupted by a gap or a frame by giving bias for a frame means to the edge of the screen and holding the screen at a prescribed position with respect to the frame means. SOLUTION: The individual screens 10 are supported while abutting on a structural frame 15. The frame 15 is formed of a frame member 20 made of extruded aluminum. The member 20 itself is constituted of a rectangular inside part 21 and an outside part 22 which is tapered forward, connected and becomes a flange 23 having a shoulder 25 extended along its length and extended forward. The periphery of each screen 10 along the back surface is notched to form a positioning notch. In such a case, in order to hold the screen 10 while abutting on the member 20, especially, abutting on the shoulder 25 of the flange 23, the screen 10 is pulled or the bias is given to the screen 10 so as to keep it at a prescribed position.
