PURPOSE:To securely clamp a photoreceptor sheet on the circumferential surface of a drum in contact by generating adequate pressing force invariably in a drum center direction and frictional force for drawing the photoreceptor to the rear end. CONSTITUTION:The leading end of a photoreceptor sheet 11 is clamped at a prescribed position of the V groove part of a drum 12 with a tip pawl 19. Then as the drum 12 rotates as shown by an arrow A, the photoreceptor sheet 11 is wound successively, but a supporting member 17 is inhibited from rotating together with the drum 12 at this time; and a clamping member 16 presses the photoreceptor 11 against the circumferential surface of the drum by a spring 18 and its turning direction is set in the direction of an arrow B through the mesh of the 1st, the 2nd, and the 3rd gears 13-15. Then, the clamping member 16 draws the photoreceptor 11 to the trailing end all the time by its friction, thereby clamping the trailing end of the photoreceptor 22 along the V groove part. |
