Abstract

PURPOSE:To perform printing having stable finishing by eliminating the effect due to the number of printing times and circumferential temp., by providing a heat generator to the single side surface of the support of a thermal head and preliminarily heating the whole of the thermal head to predetermined temp. by said heat generator. CONSTITUTION:A predetermined number of heat generating resistors 12 are provided on the support 11 of a thermal head 10 and a heat generator 13 is mounted to said support in the side opposite to said resistors 12 while a temp. sensor 14 is attached at the appropriate position between the above mentioned support 11 and the heat generator 13. Immediately after the switch of a printing apparatus is turned ON, the resistance of the temp. sensor 14 is large and voltage is applied to the heat generator 13 until said value reaches a predetermined value and the thermal head 10 is heated to predetermined temp. prior to starting printing. The printing data signal to the heat generating resistors 12 are turned ON and OFF to allow the predetermined heat generating resistor 12 to generate heat. At this time, the supply of a current to the heat generator 13 is cut off. Therefore, the thermal head is preheated to predetermined temp. regardless of the number of printing times and circumferential temp. before printing is started and, therefore, printing having stable finishing is performed.

とも良い事が判明している。By the way, in the above explanation, the preheating temperature of the thermal head 10 by the heating element 13 (Ra) was not explained, but for example, when the melting temperature of the hot-melt ink 4 is 68°C, the preheating temperature is about 50°C to 55°C. It has been experimentally found that a temperature of around 10°C is the best.

During printing, the input control wholesale pulse Pψ is set to HIGH to set the output P+ of the buffer 15 to HIGH, and the output P2 of the inverter 16 is set to LOW so that the voltage E is applied only to the terminal a, so that the power supply E is connected to the thermal head 10. It can be shared by each of the heating resistors 12 (R, , & , Rz, -Rn) and the heating element 13 (Ra) for preheating.
The configuration can also be simplified accordingly.
