Ribbon feed and elevating mechanism for typewriters or similar machines

摘要

A ribbon feed and elevating mechanism is so constructed that active parts for incrementally feeding and for elevating a ribbon from a rest position into one or more working positions form one structural unit mounted on a common shaft thereby providing a compact, easy to assemble unit for association with a typewriter of the type having a print element supported on a movable carriage. Due to the interaction of a lifting lever with a control lever and a pivoting lever to which a ribbon guide is linked, it is possible in a simple manner to raise the ribbon alternately into two different reproduction levels. A rocker, arm also mounted on the common shaft, serves to establish the increment of feed by which ribbon is to be advanced.
