摘要： When the rear side of a heat resistant substrate having heating elements formed on the front side and a cooling board are adhered with an adhesive, the heat is accumulated in the substrate. To prevent this, the portions corresponding to the heating elements on the rear side are not adhered, but are protected with cooling compound, or adhesives are applied to both sides of the cooling compound, as it is known in prior parts, but they may cause uneven heat release from the substrate to the cooling board, or sacrifice the tacky action due to wetting of the adhesive with the cooling compound. In this invention, cooling compound or cooling adhesive is spread on the rear surface corresponding to the heating elements on the substrate, and an adhesive is applied to the parts separate from that area with grooves, thereby affixing the substrate and cooling member. As a result, the layer thickness of the cooling compound or cooling adhesive may be kept constant, and excessive heating compound flows into the grooves to avoid loss of the tacky action. Thus, excellent heat release is realized, and the printing quality is enhanced.Warps and waves of the heat resistant substrate are eliminated as being pressed and fixed to the cooling board.

摘要： To the common electrode of the thermal head, the power source for heating and driving is connected to one end or both ends in the longitudinal direction of the common electrode. In this common electrode, as going from the connecting position of the power source for heating and driving, a voltage drop occurs, and the heat generation by the heating elements commonly connected to the common electrodes becomes uneven. Such uneven heat generation may lead to uneven contrast or defective coloring in the thermosensitive printing. The invention employs a conductive member which extends nearly over the entire length of the common electrode, and contacts with the common electrode over the entire length or at plural positions. As such conductive member, a metal foil or the like is used, and by inhibiting the occurrence of voltage drop, thermosensitive printing of high quality is realized.
