Abstract:
A photo printer comprising:a housing;a shaft installed inside the housing;a cantilever mechanism installed inside the housing having two arms, the two arms of the cantilever mechanism being rotatable installed on the shaft;a thermal print head installed inside the housing for printing a photo by heating a ribbon, the thermal print head having two ends and two arms installed between its two ends and the shaft for allowing the thermal print head to rotate around the shaft;a platen roller rotatably installed in the housing under the thermal print head for carrying the photo forward or backward through the thermal print head;a driving mechanism for rotating the two arms of the cantilever mechanism to move the thermal print head downward to print the photo when the photo is carried forward by the platen roller or upward when the photo is carried backward by the platen roller; andtwo adjustable elastic mechanisms installed separately between the two arms of the cantilever mechanism and the two arms of the thermal print head for allowing the two arms of the cantilever mechanism to adjustable exert force on the two arms of the thermal print head.
