Abstract
PURPOSE:To obtain a thermal head that can be miniaturized, is improved in the efficiency of use of energy, and has a simple construction, by arraying on a base a plurality of diodes capable of heating by making an electric current forward. CONSTITUTION:m Blocks each including n diodes are arrayed. The blocks are respectively connected with block terminals A1, A2...Am, and ones of diodes in respective blocks are respectively connected with element terminals B1, B2...Bn to obtain the intended thermal head. In order to drive and control the thermal head, for example, MOS transistor switches Q1, Q2,...Qn constituting part of a control circuit are provided. In this case the diodes Cij (i=1-m; j=1-n) not only have a funtion as a blocking diode for preventing backward current, but also function as heating resistor for heating recording.
