PROBLEM TO BE SOLVED: To provide a screen which has a good design and is free from wrinkles in a roll, bend, etc. SOLUTION: The structure allows a large piece of paper to be used as a screen by using thick paper pipes as holding rods of the screen. Light reflected from the screen is prevented from being thrown onto the thick holding pipes, and the screen has an innovative design. The screen can be kept wrapped around the holding pipes by pulling wires or strings, attached to the backs of the upper and lower pipes, so that the screen can be held on only the fronts of the thick holding pipes. Unlike a conventional screen as a hanging scroll which hangs right below a rod, this screen extends from the front face of the circular pipe. Accordingly, the screen can easily be rolled up and wrinkling is restrained when it is rolled up. Light reflected from a projection curtain is prevented from reaching the holding rods. Since all the parts of the screen are made of paper, they can be recycled as recyclable resource. COPYRIGHT: (C)2006,JPO&NCIPI
