Zusammenfassung: | PURPOSE:To enable the recording of a large size and to prevent the damage of the leading end of a printing head, by providing a film between an ink supply sheet and the printing head and using a conductive thermal system in the head. CONSTITUTION:An ink supply sheet 2 prepared so as to have a thickness of about 10-200mum is regularly or irregularly provided with numberless holes 2a each at least smaller than the thickness of the sheet 2 and formed of a current supply thermal material or a synthetic resin. The ink supply sheet 2 drawn up from an ink tank or the film 3 provided between the ink supply sheet 2 and a head 1 receives the supply of a current by the head 1 and generates heat as the result of the supply of a current and, by this heat, the ink 5 of the ink supply sheet 2 is flown to recording paper 4 to perform printing. By this method, not only large-sized printing is enabled but also the abrasion and damage of the head are prevented or the printing accuracy is prevented from being affected by abrasion. |
