摘要： A protective layer of a thermal head is treated with a surface-treating agent containing a chlorosilyl group-containing compound and a fluoroalkyl group-containing silane compound to form a water-repellent oil-repellent dry film thereon. Both compounds are dissolved or suspended into an organic solvent such as an alcohol solvent. The solvent can contain 0 to 10 wt % of water based on the total weight of the solvent. The surface-treating agent may have a pH of 0 to 3, and both compounds are contained in an amount of 0.01 to 10 wt % in total based on the total amount of the treating agent. The treatment lowers the surface tension of the protective layer and thus prevents deposition of melt on the thermal head for a long period of time while maintaining thermal conduction and surface smoothness of the thermal head.
摘要翻译：用包含含氯甲硅烷基的化合物和含氟烷基的硅烷化合物的表面处理剂处理热敏头的保护层，以在其上形成拒水拒油干燥膜。将两种化合物溶解或悬浮在有机溶剂如醇溶剂中。基于溶剂的总重量，溶剂可以含有0至10重量％的水。表面处理剂可以具有0至3的pH，并且基于处理剂的总量，两种化合物的含量总计为0.01至10重量％。该处理降低了保护层的表面张力，从而防止熔体长时间沉积在热敏头上，同时保持热敏头的热传导和表面平滑度。

摘要： A layer of thermal insulator is disposed on at least one of an electrically insulating substrate, an adhesive layer and a heat dissipating plate downstream to heating elements on the substrate in a supply direction of a color thermal recording sheet when executing thermal recording. In a manner that the thermal insulator is provided, when executing thermal recording on color thermal recording sheet, heat generated at heating elements is dissipated outside neither from the distal end of the insulating substrate downstream in a supply direction of the insulating substrate nor from the heat dissipating plate through adhesive layer. Since reduction in temperature is suppressed downstream in a supply direction, condensation of steam or vapor is prevented on the protective layer located at topmost of the thermal head, so that printing failure can be avoided.

摘要： A method of producing a wear-resistant protective film for a thermal head comprises depositing a wear-resistant protective film by sputtering on a thermal head which includes a substrate, and a heat-developing layer and a pair of electrodes formed on either the substrate or a heat-regenerative layer formed thereon. A layer of the wear resistant protective film is formed under a RF larger bias and another layer without a bias or with a smaller bias. Good step coverage is obtained by the RF sputter layer of the wear-resistant and the protective film prevents the intrusion of water that can cause cracking, and the layer formed under no or smaller bias reduces internal stresses and inhibits the development of cracks due to internal stresses as well as the cracking by RF sputtering.

摘要： A print head pressure mechanism is disclosed that maintains uniform pressure between the thermal print head and platen roller regardless of variations in parts precision, and thus prints with uniform print density. The print head pressure mechanism has first and second support shafts disposed at both sides in the direction of a heat element line L1 of the thermal print head, a frame member for supporting the print head, and having first and second contact parts for contacting the first and second support shafts, and an one or more urging unit for pushing the print head to the platen with the urging means operating on the side of the print head opposite the side to which the heat elements are disposed. When the platen is separated from the print head, the platen axis and heat element line L1 of the print head are not parallel to each other. When the platen is in contact with the print head heat elements, and the first support shaft is in contact with the first contact part, the platen axis is substantially parallel to the heat element line L1 of the print head heat elements.
