Abstract

The present structure provides a unique cam mechanism to be used in a ribbon feed mechanism for an impact printer which will provide for the ribbon cartridge drive, ribbon lift or oscillation, and writing line visibility. A simple and efficient mechanism of the present invention will drive and oscillate the ribbon across the print line during the normal impact printer printing operation. Then, when the printer is stopped and print line visibility is required, the mechanism will serve to tilt the cartridge downwards so that the print line can be observed.
