ABSTRACT:
A head-driving and ink ribbon feeding mechanism for an ink-transfer thermal printer comprises a print carriage mounted for parallel and non-rotational movement in a direction parallel to the platen of the printer. A support element carrying a thermal print head at a free end thereof is pivotally mounted on the carriage and is normally resiliently biased to press the thermal print head against the platen in a head-down position. Mechanical actuating means are switched selectively between a first position for advancing a thermo-ink ribbon in a cartridge received on said carriage past the thermal print head in the head-down position and to a second position in which the drive for the ribbon is disengaged and in which the elongated support element is engaged and pivoted to switch the thermal print head to a head-up position.
