Abstract:
A thermal printer for printing an image on a recording paper, said thermal printer comprising:a platen for supporting said recording paper; a thermal head being movable between a thermal-recording position to be pressed toward said platen, and an evacuation position separated from said platen, said thermal head printing the image on the recording paper interposed between the thermal head and the platen when located at the thermal-recording position; and a head-pressing mechanism for moving said thermal head between the thermal-recording position and the evacuation position, said head-pressing mechanism changing a pressure force of said thermal head in accordance with a width of the recording paper in the thermal-recording position, wherein said thermal head extends in a scanning direction corresponding to a width direction of said recording paper; said recording pacer moves in a feed direction perpendicular to the scanning direction while the image is printed; and said head-pressing mechanism changes positions in the scanning direction for pressing said thermal head in accordance with the width of said recording paper.
