Abstract

A ribbon cartridge comprises a housing having a bottom wall and a side wall extending upwardly therefrom to form an open top, a cover adapted to fit over the open top of the housing to close the housing to form a ribbon cartridge, an output arm and a take-up arm formed in the cartridge with a print space between the arms, the cartridge being adapted to hold a ribbon stuffed inside and extending between the arms from the output arm to the take-up arm, flexible fingers which are spaced apart from each other and attached at their base portions to the housing, with each finger being positioned in a finger opening in the bottom wall of the housing, whereby when an end tab of a finger meets resistance from a top wall of a correction cartridge, the finger is pushed into the interior of the housing, and when an end tab of a finger does not meet such resistance, it actuates the typewriter switch to actuate the typewriter. The method includes providing the ribbon cartridge, inserting it into a typewriter, inserting a correction tape cartridge into the typewriter, passing one of the fingers through a passage in the correction cartridge to contact the switch of the typewriter and actuate the typewriter, and blocking the other finger with the top surface of the correction tape cartridge and pushing the other finger back through its finger opening into the interior of the ribbon cartridge.
