PURPOSE:To prevent a conveyor belt from deviating and to feed an original normally, by forming independent crown-shaped parts near both the ends of a roller for conveying a wide conveyor belt in an original feeder for conveying the original, etc. with rollers. CONSTITUTION:A wide conveyor belt 4 stretched on a roller 2 and driven by it is brought in contact with the upper surface of the platen glass of a copying machine, and the original is conveyed by holding it between the platen glass and the belt 4. Grown-shaped parts 51-54 are formed near both the ends of the roller 2, and both the ends of the belt 4 ranges on both the crown-shaped parts 52, 54, thus permitting tensions tending to extend outward in the arrow direction A to act in both the ends of the belt 4, and the belt to be held stably on the roller 2. |
