<p>PURPOSE:To stabilize paper's traveling by equipping a drum case provided with a pressure spring which raises a paper traveling guide toward a photosensitive drum and a stopper part which presses down the end part of the paper traveling guide. CONSTITUTION:The pressure spring 2 always works to raise the paper traveling guide 3 in the direction of an arrow and a limit bracket 4 becomes a stopper in a state where the drum case 5 is not inserted. When the drum case 5 is inserted into a main body, the stopper part 6 of the drum case 5 presses down the paper traveling guide 3, which is rotated to be moved with the aid of a rotation part 7 on the end of the paper traveling guide 3. By controlling only the position of the photosensitive drum 8 inside the drum case 5 and the position of the stopper 6, a gap between the photosensitive drum 8 and the paper traveling mechanism part can be kept constant without adjustment. Thus, the paper can be made to stably travel.</p> |
