CONSTITUTION:An ejection roller 11 is formed by mounting a rubber roller 12 with which a plurality o protrusions 14 are integrated, on a shaft 13, while a spacer 15 which is larger than the rubber roller 12, and which is lower than the protrusion 14, is provided in the center of the rubber roller 12. It is preferred that the spacer 15 is formed of resin or metal which is harder than the rubber roller 12.</p> |
