Abstract

Abstract A drawing table is provided, which has a top hingedly connected at a first end thereof, to a first end of a base, so as to be pivotable between a closed position, and at least one open position with respect to the base. At least one arm, and preferably a pair of arms, are provided, which are movable to an unextended position when the top is in the closed position and in which the arm or arms lies substantially parallel to the top and the base, and one or more extended positions. Each extended position corresponds to an open position of the top. Retaining means preferably of a releasable adhesive material, such as that sold under the trademark VELCRO, releasably retain each arm in each extended position. A flexible reflector sheet is connected to the top and extends between opposite edges of a transparent surface in the top, so that the reflector sheet will lie within the frame when the top is in the closed position, and can curvedly extend beneath the transparent surface when the top is in the open position, thereby reflecting light from a light source through the transparent surface.
