  • Patent number: 5967483
    Abstract: A rotatable, free standing copy holder with a relatively narrow base structure upon which is mounted a cylindrical drum to which sheets of standard office size paper containing written or printed information may be clamped at the top margin. The configuration of the base permits the lower portion of the sheet of copy to be tucked in a loose roll into the open space in the base under the drum. To scan the sheet of copy for further processing, the drum is manually rotated clockwise by means of thumb wheels attached to each end of the drum. When the drum is being rotated, the sheet of copy passes under a window that is cut into the base wall while it is progressively being rolled up on the drum. This allows the copy to be seen and processed a few lines at a time and blocks out the copy that has already passed across the window as well as the copy still to be rotated past it.
