Abstract
Abstract A facsimile device or an electrophotographic copying machine includes a paper feeding section for supplying a copy paper derived from a roll-paper to an image forming section. A housing of the facsimile device or the electrophotographic copying machine includes a rotatable cover for exposing the paper feeding section when required. A pair of first supporting members are secured to the both side ends of the paper feeding section for rotatably and demountably supporting the roll-paper. A pair of second supporting members are secured to the rotatable cover for preliminarily supporting the roll-paper when the rotatable cover is opened. The roll-paper preliminarily supported by the second supporting members is transferred to the first supporting members when the rotatable cover is closed.
