ABSTRACT:
A feed mechanism for advancing a cartridged ink ribbon in feeding steps whose length is determined dependent upon the type of the ribbon contained in the ribbon cartridge. The feed mechanism includes a feed roller mounted in the cartridge and operatively connected with the ribbon for advancing the ribbon. The feed mechanism further includes a driving device mounted in the machine and operatively connectable to the drive roller upon insertion of the cartridge in the machine. The driving device has at least two output components arranged to rotate with unlike speeds. The feed mechanism further has a coupling arrangement mounted in the cartridge and continuously operatively connected with the feed roller. The coupling arrangement connects a selected one of the output components to the feed roller when the cartridge is in place in the typing machine. The coupling arrangement is structured such that it connects the feed roller to the selected one of the output components as a function of the type of the associated ribbon.
