Abstract
A document stand to support paper (or other flexible sheet material) for use as a copy holder while typing or for use to display graphic matter. Using a form with a bent slot on the device's top surface, it allows the bottom edge of either a single or multiple sheets of paper to fit into it. The slot engages the paper in an arc which allows the paper to use its own inherent strength to support itself in an upright position. The flexible paper conforms to this slightly curved shape of the slot allowing it to remain upright without additional rear, side or top supports. This upright position of the paper is tilted slightly back to both increase stability and ease of viewing of the document.
