Paper sheet transport mechanism in copiers - uses two rollers with elasticised cover and rigid end spacer supports for slit size maintenance

摘要

A two roller transport mechanism is for sheet paper and is for use in such equipment as copiers. The exact slit size between the rollers is precisely adjusted. The rollers are equipped with an elastic outer on a central shaft. The elasticised outer portion of the rollers is contained between end plates of the same dia. as the elasticised section. The end plates are connected to the central shaft and serve to preserve the shape and dia. of the elasticised cover and maintain the accuracy of the slit size between the pair of rollers.
