PURPOSE: To prevent the deterioration of quality of an image because of the generation of difference in the printing density by disposing a torsion bar provided with folded sections at both ends on an upper section of a thermal head of a thermal printer, applying the impression force to the ...
;CONSTITUTION: A torsion bar 3 provided with folded sections 6 and 8 on both ends is disposed on an upper section of a thermal head 1 of a thermal printer. At the time of printing, impression force is applied to the folded sections 6 and 8 of the torsion bar 3, and printing pressure...
