IPC: B41J2/335
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To almost uniformize a pressure of an area held between buffers and effectuate good printing by setting the buffers higher than a heating element to both sides of the heating element. SOLUTION: The thermal head has buffers 12 set to both sides of a heating element 11. Each of the heating element 11 and two buffers 12 is set linearly in a longitudinal direction of the thermal head. The heating element 11 and two buffers 12 hold a relationship that top parts agree in height with a platen circumferential face. Even when a thermal head substrate 10 is uneven in the longitudinal direction, the relationship is rendered almost constant at whichever part of the heating element 11. Even if a contact pressure of a platen to the two buffers 12 changes large by a degree of the unevenness, a contact pressure of a part held between the two buffers 12 is almost constant and a density difference in printing is reduced. Printing is conducted well accordingly.
