ABSTRACT:
A ribbon and tape feed mechanism for a single element typewriter is disclosed. The ribbon feed mechanism and correction tape mechanism are mounted and configured to oscillate with the ribbon and correction tape cartridges when the cartridges and support therefore are tilted to present a portion of the ribbon or the correction tape to the print point of the typewriter for impact. The ribbon feeding and the tilt control of the cartridge is accomplished from a single cam having a plurality of sets of rises. The correction tape feed is driven from a second cam which is only engaged during those machine cycles when the machine is in a correction mode. The control of the correction mode is through the depression of the rear of the cartridge thus effecting the raising of the front portion of the cartridge and the correction tape to its operative position.
