ABSTRACT:
A thermal head includes a heating resistor group which consists of 2n pieces of strip-like heating elements, n pieces of buffer elements for driving the heating elements, wherein the heating elements are adjacently paired for one buffer element so as to enable one of the paired heating elements to be energized, a first common electrode and a second common electrode for energizing the heating elements through the buffer elements, wherein the heating elements are adjacently paired for being connected to the first and second electrodes alternately, a 2n-bit shift register for storing printing data for the heating resistor group, n pieces of multiplexors for selecting one of the 2n-bit signals which are adjacently located in the parallel outputs of the shift register according to the output timing of the first and the second common electrodes, thereby applying the selected signal to the buffer elements.
