Abstract (en)
[origin: US4294553A] An inked-ribbon feed mechanism comprises an electric drive motor (5), reversible for reversing the ribbon feed direction, and a reversing switch (32) for the motor (5). A roller (31) operating the reversing switch (32) travels along a cam (28, 29) formed on one arm (21) of a lever (19, 20, 21). A further arm (19) of this lever carries one (14) of two ribbon guides (13, 14) coupled with each other. The motor (5) drives a worm (6). A worm wheel (7) is firmly connected to a pinion (8) and is displaceable together with the latter along the worm (6) in two positions. In one position (8) the pinion meshes with a toothed rim (3) provided on one of the two ribbon spool carriers (1). In the other position (8') the pinion meshes with a toothed rim (4) formed on the other ribbon spool carrier (2).
