ABSTRACT:
A document or other record media along with an associated inked ribbon and a type character are pressed together at the same time from two sides by means of two pressing members pivoted on a common shaft. The pressing members are connected with a toggle linkage which is caused to be actuated from a home position to a printing position and return. The actuation of the linkage moves a platen and a hammer towards each other to perform the printing on the document.
