    摘要： In a printing apparatus using a plurality of heating elements as printing elements, there are provided CCD elements for storing electric charges whose quantity correspond to temperatures in correspondence to each of the printing elements, and for sequentially transferring these electric charges. As a printing head driving apparatus, an analog shift register having a series of CCD elements is employed in order to perform data transfer operation, data alignment, and driving operations of the respective printing elements. Also, the above-described CCD elements are commonly used with CCD elements for storing and transferring temperature data. As a result, a compact printing apparatus can be made while suppressing shading in images caused by temperature increasing due to the driving operation of the printing elements.

    摘要： An ink jet head comprises a plurality of discharge pressure generating elements serving as the discharge pressure source for discharging an ink droplet, an orifice plate having a plurality of ink discharge ports corresponding to the respective discharge pressure generating elements formed therefor, an ink supply port for supplying ink and a nozzle wall forming an ink flow path communicating the ink discharge ports with the ink supply port. The orifice plate and the nozzle wall are formed by resin material, and also, a thin metallic film is formed on the outer surface of the orifice plate. If desired, a water-repellent film is formed further on the surface of the thin metallic film. With the metallic film formed on the surface of the orifice plate, the moisture in ink is effectively prevented from being evaporated. Further, with the provision of the metallic film, it becomes possible to perform the eutectoid plating for the formation of the water-repellent film. With the head thus structured, it becomes possible to stably obtain excellent print quality.
