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.

Integrated ribbon mechanism

A portable printer comprising a door pivotally coupled to a main body of the portable printer at a back end, a printing medium roller support rotatably mounted on the door of the portable printer, a platen rotatably positioned at a front end of the door, a door locking mechanism having a pair of door locking latches respectively positioned at opposite ends of the platen, a roller movably and rotatably coupled to the door locking mechanism and positioned parallel to the platen, a pair of levers movably coupled to the door locking mechanism for pressing the roller against the platen when the door is closed to the main body, a support frame positioned within the main body, a print head pivotally coupled to the support frame, a pair of coil springs coupled between the print head and the support frame such that the print head is essentially floating against the support frame, a body locking mechanism having a pair of body locking latches for latching with respective door locking latches, a gear system coupled to the platen for rotating the platen, a door lock preventing the door locking mechanism from being pressed to release the door, a printing medium sensor and a status indicating lamp for sensing and reporting the status of the printing medium roll, wherein the medium roller support is mounted on the door for easy accesses of the printing medium roll and the print head is adjustably positioned against the platen.
