Abstract
A resilient ribbon mask for an impact printing apparatus which includes a print head is mounted for sliding movement on a frame connected to the print head. The frame and mask are angled away at either side of the print head from the surface of the platen along which the print head travels in a line printing operation. A slot in the mask for allowing passage of printing elements therethrough is oriented with its long dimension parallel to the direction of print head travel, and extends into the angled portions of the mask on each side of the print head so that the slot ends do not engage the record media being printed upon. The ribbon mask is held in close proximity to the print head during printing operations, but is permitted to spring away from the print head at the end of a line being printed, in order to facilitate ribbon changing and record media insertion and removal.
