Title: Integrated ribbon mechanism

Abstract: An integrated ribbon mechanism comprises a support frame having a bottom plate and two side plates integrated to the bottom plate at opposite sides, a print head assembly rigidly mounted on the bottom surface of a bottom plate, first and second pivotal holes positioned on opposite side plates of the support frame, and a pair of locators positioned at opposite side ends of the print head assembly, each locator having an extrusion portion positioned within a respective slot of the drive mechanism during operation wherein the extrusion portions are smaller than the slots of the drive mechanism to allow the integrated ribbon mechanism to slide against a drive mechanism, the integrated ribbon mechanism being pivotally and adjustably coupled to the drive mechanism by a pair of pivot pins that are smaller than the first and second pivotal holes to allow the integrated ribbon mechanism to slide against the drive mechanism wherein a ribbon strip mounted on the integrated ribbon mechanism will be pulled by a platen of the drive mechanism to align the print head assembly with the platen during operation without losing alignment of the print head assembly with the support frame.
