ABSTRACT:
A method and mechanism for automatically performing typewriter functions such as backspacing and disabling the escapement mechanism of a typewriter. A ribbon cartridge carrying actuating abutments is inserted into the typewriter whereupon the abutments engage a mechanism to actuate a selected function as for example the backspace mechanism and also engage another mechanism to disable the escapement mechanism. Particularly adaptable to correcting typing errors, the present invention will minimize the manipulations now necessary to perform an error correcting operation. Having typed an erroneous character, the operator simply inserts a ribbon cartridge containing the actuating abutments. One of the abutments contacts an actuating mechanism within the typewriter to backspace the carriage. The second abutment contacts a second actuating mechanism within the typewriter to disable the escapement mechanism to prevent carriage movement during error correction or until the ribbon cartridge is removed. Other selected typewriter functions can also be actuated by cartridge insertion.
