Abstract
A ribbon cartridge has a ribbon re-inking mechanism which is made up of a porous rubber or elastomer ink roll journaled on a fixed shaft and in contact with an ink transfer roll journaled on a pivotable member and rockable against the ink roll. The ink ribbon provides the force necessary to urge the transfer roll in contact with the ink roll and also to drive the rolls in normal operation. A modified arrangement includes a balancing roll to enable proper operation of the re-inking mechanism in different orientation and movement of the ribbon cartridge and to increase re-inking sensitivity.
