It is an object of the present invention to provide a self-standing manually operated elevating screen which makes it possible to raise and lower the screen over a long period of time without encountering any trouble such as damage, deformation or the like, and which makes it possible to simplify the construction used for this purpose. The upper-end supporting member 4 to which one end of the screen 1 is connected and the base member 3D to which the other end of the screen 1 is connected are pivot-connected by left and right linking mechanisms 5, 5. Urging means 16, 16 which are used to urge the lower side arms 13, 13 upward are provided, and slide members 20, 20 that are free to slide are fit over either the let and right upper side arms 11, 11 or the left and right lower side arms 13, 13, or both. These left and right slide members 20, 20 are connected so that these members are free to rotate in relative terms on a vertical line S that is positioned in the approximate center of the screen 1 in the transverse direction of the screen.
