Zusammenfassung:PURPOSE:To reduce driving load over the entire pressing process, by causing a time shift at a time of increase of resilient deformation between first and second resilient members when a print head and a ribbon stopping section are pressed against a print sheet through an ink ribbon. CONSTITUTION:During correcting operation, cams 58, 108 rotate to the right, and a correction lever 38 rotates on a first cam face 110 of the cam 108 so as to bring a correction plate 98 near to a platen. A thermal head 22 starts stroke on a first cam face 90 of the cam 58 with a delay, and contacts with the platen, then a second cam face 112 causes to start resilient deformation of a plate pressing spring 100, thus transferring to pressing process. Upon completion of pressing process, the thermal head 22 contacts with the platen through an ink ribbon, and pressing is started through the second cam face 92. Then a stable pressing condition is brought out by means of third cam faces 114, 94 where the ink ribbon is pressed against a print sheet and a carriage 10 is moved under this condition so as to make a correction.
