Abstract
A method and mechanism for automatically performing typewriter functions such as backspacing a carriage. The backspace mechanism is actuated by the insertion and removal of a ribbon cartridge that is placed on and guided by a ribbon cartridge platform and is especially suited for use in conjunction with the correction of erroneously typed characters. The ribbon cartridge carries a pair of cam surfaces that engage a pair of typewriter backspace coupled cam surfaces to actuate a backspace function upon insertion and again upon removal of the ribbon cartridge. Therefore, automatic multiple backspacing of the typewriter carriage occurs when performing an error correcting operation simply by inserting and removing a correction ribbon cartridge. Although a backspace function has been selected for purposes of demonstration, the hereafter disclosed embodiment may be utilized to actuate other typewriter functions upon the insertion and removal of the ribbon cartridge.
