Abstract

PURPOSE:To obtain a compact thermal head, which contributes to the miniaturization and wt. reduction of machinery, reduced in a heat accumulation phenomenon and excellent in a heat dissipating/cooling characteristic, by providing a heat dissipating member having flexibility on a substrate having a heat generating element formed thereto or at least on one flat surface of a base stand in a closely adhered state. CONSTITUTION:When high speed recording or multicolor multigradation recording is performed, it is necessary to increase the dissipation capacity of heat from a heat dissipating member 4 in order to reduce the heat accumulation phonomenon on a heat generating element substrate 2 accompanied by recording but correspondence can be taken by increasing the number of metal foils 4a constituting the heat dissipating member 4. Further, in such a case that it is difficult to increase the heat dissipating member 5 from the constitutional restriction of machinery, by fixing a fixing member 5 to the housing of the machinery in a closely adhered state, the housing can be used as a part of the heat dissipating member and, therefore, heat dissipating capacity can be secured without increasing the number of the metal foils 4a. Because a thermal head and the housing of the machinery are connected by the heat dissipating member having flexibility, any effect is not exerted on a head revolving operation at the time of the charging of paper and this constitution can contribute to the miniaturization and wt. reduction of the machinery.
