Abstract

Abstract An apparatus for supporting and storing drawings, such as blueprints, includes an elongated outer casing having an elongated opening therein. A pair of end caps are attached to each end of the casing with each end cap having a hub formed therein to hold a central shaft inside the elongated outer casing. A flexible support surface is attached to the central shaft and is rollably mounted in the casing and protrudes through the elongated opening in the casing for removably supporting a drawing thereon. A flexible, transparent cover may be supported over the flexible support surface for holding drawings or blueprints therebetween. A gripping handle is attached to one end of the flexible support surface exterior of the casing for pulling the drawings out of the casing. One end cap is attached to the elongated shaft while the shaft is rotatably supported in the other end cap to allow the drawings and support surface to be rolled back into the casing by rotating the one end cap.
