A portable, light-weight, foldable, support device for papers, portable computers, bingo cards and the like, the device formed from lightweight, plastic, planar, spaced upper and lower parallel sheets separated by integrally-formed, spaced, parallel ribs laterally extending between said sheets from one side edge of the said sheets to an opposite side edge, the upper sheet having a plurality of linear cuts, each cut running through the upper sheet from the one side edge of the said upper sheet to the opposite, each cut being between a different adjacent pair of the said ribs to permit the folding of the device about a corresponding fold line in the lower sheet formed between those same ribs, the cuts and corresponding fold lines being of a number and spaced so as to form, in the device, in sequence, a working surface panel, an elevation panel, a support panel, and a lip panel, these panels foldable, about the fold lines in the lower sheet, in one direction out of the plane of the sheets, into an operative configuration of the device so that said working surface panel is upwardly and rearwardly inclined with respect to a horizontal working surface on which the device may rest, and the said working surface panel is supported at a lower front edge of the said working surface panel on said horizontal support surface, and at its upper rear edge by the other panels, said panels provided with securing means for reasonably holding the said panels in the operative configuration.
