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.

Ribbon feed and elevating mechanism for typewriters or similar machines

An electromechanical printer having characters of a type font located on radial spokes of a circular type disc is disclosed. The type disc is normally arrested and connected to be driven about its axis by a unidirectional motor source via a slip clutch. Selection-print activating mechanism responsive to source, e.g. keyboard, generated mechanical outputs serve to select a character stop, in an assembly of character stops, corresponding to characters located on the spokes of the type disc and, incident to selection of a character stop, to release the normally arrested type disc. The type disc is provided with counterstops adapted to engage selected character stops positioned in the path thereof and to move the character stop assembly to a frame supported final positioning stop which arrests the type disc with the selected character opposite a print point. The encounter of the character stop assembly with the final positioning stop is employed to operate a print hammer to drive the selected character against a platen to print. Following printing, means are provided to reset selected character stops and to restore the character stop assembly to normal position.
