Abstract
A thermal printer has a thermal printhead mounted on a pivot frame which is movable from a working position where the printhead is in position to print from a thermal ribbon onto a substrate, to an open position which permits access to ribbon take-up and supply rolls. The printhead is pivotally mounted to the pivot frame, and its pivoting is controlled by a cam so that the sensitive thermal print element of the thermal printhead remain at a position that permits access to the ribbon and other printer working components, without exposing the print elements so they can easily be contacted by a person servicing the printer. Cooperating guide members are used for controlling the orientation of the printhead as the pivot frame moves between a working position and an open position.
