<p>PURPOSE:To provide a driver solved for thermal printing head, which realizes very fine and high speed printing, by a method wherein the battering of image developing between the picture elements on one line and in the previous line or adjacent to each other is soled through simple driving circuit structure with out complicating the driving circuit structure. CONSTITUTION:Timing controlling circuit 9 performs time-division driving by bit unit such as on alternate picture elements or on every three picture elements so as to prevent heating elements 1 adjacent to each other from generating heat simultaneously. In addition, since the above-mentioned timing control is performed on the basis of one strobe signal input with one timing controlling circuit 9, the battering of image can be solved under the condition that the structure of a driver 13 is easily obtained at low cost.</p> |
