PURPOSE:To enable independent adjustment of each feeding belt, absorb variation in form and accuracy of part, elongation of feeding belt, deflection of each roller, etc., enable highly accurate adjustment of pressing force against cylinder glass such that it is uniformed or increased at the center and decreased gradually toward both ends, and prevent wrinkle from occurring and a part of image from being unclear. CONSTITUTION:Multiple pressing rollers 13 are provided in press contact with each feeding belt 3, multiple adjustment screws 15 to adjust the pressing force of the pressing rollers 13 against the feeding belt, and multiple elastic members which are located between the pressing rollers 3 and the adjustment screws 15 and absorb the fine vibration of the feeding belts 3. The multiple elastic members are pressed against each feeding belt 3 to adjust the tension of each feeding belt 3 applied to a cylinder glass 1. |
