ABSTRACT:
There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head and to which another cam is secured for driving an operating lever. The cam means is part of a lost-motion connection which couples the slide to the inker. As the operating lever is cammed in one direction to move the feed finger forward, the inker is moved into and out of inking cooperation with the print head assembly. Both an ink cartridge and an ink pad assembly are mounted on yieldable supports to promote uniform pressure contact and hence uniform inking. The print head is provided with toothed drive wheels and one or more intervening blank elements or spacers each having tooth surfaces defining a gap or space which enables an indexing gear to be shifted smoothly relative to the toothed drive wheels.
