Abstract
A roll paper handling device for use in various recording machines, such as facsimiles and copiers, which employ recording paper in the form of a roll is provided. The present device includes a box in which a roll of paper may be rotatably installed in position which may be moved between an operative position where a lead out paper portion unrolled from the roll may be fed to a desired location and an inoperative position where the roll of paper may be replaced and a locking mechanism which allows the box to be moved to the inoperative position only when said lead out paper portion has been completely pulled back into the box. The locking mechanism is also so structured so as to apply a back tension to the roll of paper thereby allowing to prevent the roll of paper from rotating exceedingly.
