Pressure adjusting mechanism for adjusting pressure of a thermal print head and thermal sublimation printer therewith

A thermal sublimation printer, comprising:

• a holding roller for holding a print medium;
• a thermal print head for transferring a dye on a ribbon onto the print medium;
• and
• a pressure adjusting mechanism for adjusting pressure applied on the thermal print head, the pressure adjusting mechanism comprising:
• a pressing plate disposed above the thermal print head, the pressing plate comprising a first pressed section and a second pressed section connected to the first pressed section;
• a plurality of resilient members connected to the first pressed section of the pressing plate and the thermal print head and to the second pressed section of the pressing plate and the thermal print head, respectively;
• and
• a pressure adjusting member pivoted to the pressing plate, the pressure adjusting member being for driving the pressing plate to move relative to the thermal print head, so as to press the plurality of resilient members for providing the thermal print head with pressure, such that the plurality of resilient members drives the pressing plate to pivot relative to the pressure adjusting member for equilibrating the pressing plate.
