ABSTRACT:
A device (10) for magnifying material embodied in a tangible medium (12), such as a writing, drawings, photographs, pictures, and the like. The device (10) includes a transparent base (14) for placing over the tangible medium (12) to be magnified, the base (14) having a bottom side edge (16) and a U-shaped lip (18) connected to the bottom side edge (16). Extending upwardly from the bottom side edge (16), the U-shaped lip (18) extends inwardly over the bottom side edge (16) of the base (14). The device (10) also includes a magnifying sheet (20) with a basal edge (22) which is engaged by the U-shaped lip (18). An adjustable fastener (24) extends between the magnifying sheet (20) and the base (14). The adjustable fastener (24) allows the magnifying sheet (20) to be selectively supported in an inclined position above the base (14) so that the indicia in the tangible medium (12) to be viewed are magnified in an amount determined by the selected angle of inclination (.alpha.) of the magnifying sheet (20) and the base (14).
