PURPOSE:To prevent a laterally striped stain due to the pressing of a roller from being formed even when a wait time becomes long by separating conveyor rollers which contact a photosensitive surface from master paper in the wait time of the master paper. CONSTITUTION:The conveyor rollers 21 and 22 in front of the cutting part 3 of a master paper feeding device are constituted so as to leave each other in the wait mode of the master paper 2. A hydraulic cylinder 24 is arranged as a separating means below the bearing case 23 of the roller 22. Then, a piston 24a is elevated by 1-3mm in the wait state with hydraulic pressure and the roller 22 is separated from the master paper 2 to release the paper from being pressed. Therefore, even when the wait time becomes long, a laterally striped stain due to the pressing of the rollers 21 and 22 is prevented from being formed after development. |
