Abstract
A roll-up apparatus is provided for automatically rolling up a plurality of media sheets, such as original documents being copied or output copy sheets. In one embodiment, a plurality of flexible, circular guide members are aligned perpendicular to the media sheet feed motion. The first and succeeding sheets are scrolled up within the circular interior space formed by the guide member. The guides are designed to expand radially outward along their width to accomodate the increasing area of successively rolled up media sheets.
