Abstract
A rolled screen drawer includes a take-up roll (1) rotatably mounted on a support member (2), a first screen (3) wound on the outermost periphery of the take-up roll, at least one additional screen (4) wound on an inside of the first screen, an engagement (Sa, Sb, Sc) capable of engaging the inside of the leading end of at least one additional screen with the outside of the first screen, and a leading member (6b, 6c) provided at the leading end of at least one additional screen. It is thus possible to selectively expose any desired screen to view.
