Abstract: @ A ribbon lift and feed mechanism for a typewriter/ printer (10) in which the print ribbon cartridge (15) has deflectable arms (16a, 16b) for placing the ribbon (13) in a position confronting the platen (11) of the typewriter (10). On the platform (40), supporting the ribbon cartridge (15), is a shuttle (50) which is remotely oscillated as by a drive motor (90) on the frame (12) of the typewriter (10). Translation of the shuttle (50) and the cam (66) associated with the shuttle (50) effects movement of cam follower (66a) engageable with the cam (66), causing the deflectable arms (16a, 16b) of the cartridge (15) to oscillate between a rest and elevated position to place different portions of the print ribbon (13) intermediate the type element (23) and the platen (11). The shuttle (50) also carries ribbon feed drive means (85) which cause an incremental feed of the ribbon (13) after the ribbon has been struck at multiple elevated positions. Moreover, by placing a correction ribbon cartridge (30) beneath the ribbon cartridge (15), another cam (70) on the shuttle can effect platform (40) elevation when it is desired to dispose the correction ribbon (31) intermediate the printing element (23) and the platen (11). This action occurs as a result of the oscillation of the shuttle (50).

Abstract: A method of and apparatus for proportional ribbon (23) tracking on a printer including a printwheel (25), ribbon (23) and hammer all mounted on a carrierfortranslation opposite a platen (21). Ribbon lift mechanism (17,47) is provided for effecting elevation of ribbon (23) to multiple predetermined positions or tracks so that characters may be printed on print receiving medium (22). Input means (11) receives a character to be printed. The microprocessor (13), in conjunction with the ROM (15), characterizes the character in accordance with a predetermined plurality of characteristics. In accordance with ribbon lift and fed algorithms, a particular characteristic of the character to be printed is added to a position on the ribbon upon which at least one prior character has been printed. In this manner a new print position is determined. Thereafter, the new track print position is outputted to the ribbon lift and feed means (17,47,18) for effecting elevation of said ribbon (23) to one of a multiple of predetermined positions to thereby approximately maximize the number of predetermined positions of said ribbon with characters thereon which may be printed without character overlap.
