    Abstract: An inkjet head includes a head cap for protecting an ink discharge surface of a print head and a cleaning roller for cleaning the ink discharge surface of the print head. The head cap moves relative to and is removably mounted to the print head including the ink discharge surface with an ink discharge hole for discharging ink supplied from an ink cartridge. The cleaning roller is provided at a print head side of the head cap in the longitudinal direction of the print head. By virtue of this structure, it is possible to reduce the size of a printer body. The invention aims at reducing the size of the printer body by providing the cleaning member at the head cap for protecting the ink discharge surface.

    Abstract: A printer device for realizing correct representation of the gradation. After oozing a quantitation medium (45) from a quantitation medium nozzle (53), the printer device causes an emission medium (49) from an emission medium nozzle (54) for mixing with the quantitation medium (45) for emitting the resulting mixed liquid. During the time which elapses since emission of the quantitation medium (45) from the quantitation medium nozzle (53) until reversion of the liquid surface of the quantitation medium (45) to the opening end of the quantitation medium nozzle (53), the quantitation medium (53) is pressurized in a direction of pulling the liquid surface of the quantitation medium (45) into the quantitation medium nozzle (53). Also, during the time which elapses since the emission of the emission medium (49) from the emission medium nozzle (54) until reversion of the liquid surface of the emission medium (49) to the opening end of the emission medium nozzle (54), the emission medium (49) is pressurized in a direction of pulling the liquid surface of the emission medium (49) into the emission medium nozzle (54).

    Abstract: A printing head that prevents ink, diluent, and a mixed solution thereof from adhering to a spreading about a portion of the printing head around a nozzle. A printing apparatus using such a printing head has an enhanced ability to reproduce a gradation of concentration, thereby making it possible to form a recorded image of high resolution. The printing head has a first nozzle (34), which discharges a discharge medium, and a second nozzle (36), which discharges a metering medium. The orifices of the first and second nozzles are adjacent to each other in a nozzle outlet face (38a) of the printing head. A groove, a hydrophilic portion, or an insular projection is formed between the first and second nozzles to control the spread of ink, diluent, and a mixed solution thereof around the nozzles. The hydrophilic portion may be made by a non-processed portion of the outlet face of the printing head, and a portion other than the non-processed portion may be made a hydrophobic portion. Several variations of the groove, hydrophilic portion, and insular projection are disclosed.

    Abstract: A print head is provided with at least ink-pressurizing cells, heating elements, and ink-ejection nozzles. In addition, the print head includes substrate members which form side surfaces and one end surface of the ink-pressurizing cells, and which are provided with the heating elements; a nozzle-formed member which forms the other end surface of the ink-pressurizing cells, and in which the ink-ejection nozzles, which individually correspond to the ink-pressurizing cells, are formed; and a head frame which supports the nozzle-formed member.

    Abstract: The present invention provides a printer which enables to prevent dispersion of a quantitative medium in a discharge medium during a wait period of time, so as to realize an accurate quantification of the quantitative medium to be mixed with the discharge medium, which enables an accurate gradation expression. The printer includes a printing head having quantitative nozzle communicating with a quantitative medium pressure chamber (53) into which a quantitative medium (45) is introduced and a discharge medium nozzle (66) communicating with a discharge medium pressure chamber (54) into which a discharge medium (49) is introduced. The quantitative medium (45) is made to seep out from the quantitative medium nozzle (64) toward the discharge medium nozzle (66) and after this, the discharge medium is discharged from the discharge medium nozzle to be mixed with the quantitative medium so that the mixture obtained is discharged. The quantitative medium nozzle (64) has an opening of, for example, a crescent shape, i.e., a circular shape with a cut-off portion, and is positioned in such a manner that the nearest point on the opening end of the quantitative medium nozzle from the center of figure of the quantitative medium nozzle faces the discharge medium nozzle which opens adjacently.
