PURPOSE:To enable the operator to confirm printed images simultaneously with printing, by forming a thermal head from a transparent material. CONSTITUTION:For example, a substrate 11a formed of a transparent material such as a glass is provided with thin film patterns 11b... on the side for contact with a thermal recording paper. heating resistors 11c,... are provided at a part by setting the pattern width to be sufficiently narrower than at other parts. When an electric current is passed to an arbitrary one of the patterns 11b,..., the heating resistor 11c generates thermal energy for developing the color of the thermal recording paper 6, since it has a high resistance. Accordingly, printed images can be instantly confirmed, and the operator can instantaneously find a misprint or the like. |
