ABSTRACT:
A method of assembling an ink ribbon cartridge comprises inserting a leaf spring having a mounting frame and a flat spring finger that longitudinally extends from the mounting frame, beginning at an opening in the mounting frame, and at an acute angle from the opening, into a housing-half to position the spring finger pointing at the acute angle into the housing-half, and inserting an ink ribbon spool having opposite hub ends and a rotation axis into the housing-half, laterally relative to the rotation axis, to cause one of the hub ends to depress the spring finger at least partially into the opening, whereby the spring finger will urge the spool in one direction along the rotation axis.
