ABSTRACT:
This is a system for holding a supply roll of media in a plotter or the like. One support bar is of fixed length and has a sliding lockable collar for use with different widths of media. Another support bar is of adjustable length for use in plotters employing different widths of media. The end holder for the support bar includes a biased member holding the end in a U-shaped slot to resist lifting from forces on the supply roll as the media is removed.
