PURPOSE:To facilitate manufacture and to carry a paper reliably with high accuracy, by coating the outercircumference of core metal molded to be thicker in the central portion with rubber and forming into a tube. CONSTITUTION:The outercircumference of core metal 17 molded to be thicker in the center is coated with rubber 18 and formed into a tube. Since the rubber 18 is not required to be polished in accordance to the profile of core metal 17, manufacture is facilitated considerably. While since the core metal 17 is thicker in the center, the thickness of rubber is different at the central portion and the opposite ends to provide such effect as similar with a paper feed roller resulting in highly accurate and reliable paper feeding. |
