ABSTRACT:
A copyholder (10) includes a concave generally crescent-shaped rear support wall (20) and a forward support wall (32) that has another support edge (30). The support edge (30) substantially parallels and is spaced from the rear support wall (20) to form a curved sheet-receiving slot (18) that is generally concave with respect to the forward support wall (32). Rear support wall (20) is also tilted back away from the forward support wall (32) at a tilt angle (50) from vertical. When a sheet (16) is inserted into the sheet-receiving slot (18), the sheet (16) is bent along its vertical axis (42) and is tilted back away from the forward support wall (32) at the tilt angle (50). The tilt and the bend provide stability to the sheet (16) and prevent it from collapsing while it is held at a convenient viewing angle.
