Definitions

  • the printer is of a so-called intermixing type in which ink and diluent are mixed together in an interior of the ejection nozzle.
  • a printing device including an ejecting nozzle with a first discharge opening and a metering nozzle with a second discharge opening, which are provided separately from each other to feed two kinds of fluids through the first and second discharge openings, respectively, the two kinds of fluids being mixed together to form a fluid mixture to be ejected toward a recording medium, wherein a minimum distance d between the first and second discharge openings of the metering and ejecting nozzles is in the range of 0 ⁇ d ⁇ 5 ⁇ (S1) where S1 stands for an opening area of the first discharge opening of the ejecting nozzle.
  • a printing device including an ejecting nozzle having a first discharge opening and a plurality of metering nozzles each having a second discharge opening, which are provided separately from each other to feed fluids through the first and second discharge openings, the fluids being mixed together to form a fluid mixture to be ejected toward a recording medium, wherein a minimum distance d between the first discharge opening of the ejecting nozzle and the second discharge opening of each of metering nozzles is in the range of 0 ⁇ d ⁇ 5 ⁇ (S1) where S1 stands for an opening area of the first discharge opening of the ejecting nozzle.
  • such a printing device has an orifice plate in which the ejecting nozzle 1 and the metering nozzle 2 are separately provided.
  • the orifice plate 3 may be a plate-like or film-like member made of metal such as nickel or stainless steel, a ceramic material such as glass or silicon, or a plastic material such as polyimide or polyethylene terephthalete.
  • the metering nozzle 2 has a large degree of freedom with respect to the shape of the discharge opening 2a.
  • the shape of the discharge opening 2a is not limited to a circular shape but any shape such as, for example, an ellipsoidal shape, a triangular shape or a crescent shape as shown in Figs. 3A to 3C is applicable.
  • the discharge opening 2a having any of these shapes can be easily formed by varying the shape of a mask used in a laser-machining process. For example, if an intended shape of the discharge opening 2a is a circle, it can be formed by using a mask having an ellipsoidal shape.
  • the opening area S2 of the discharge opening 2a of the metering nozzle 2 is preferably in the range satisfying the condition of 5/10,000 ⁇ S2/S1 ⁇ 10.
  • the ratio S2/S1 of the opening area S2 to the opening area S2 exceeds 10, ink spreads over an area surrounding the discharge opening so that an accuracy for metering the ink is deteriorated.
  • the ratio S2/S1 is less than 5/10,000, the amount of ink to be metered at one metering cycle becomes too small.
  • the afore-mentioned opening area S2 is in the range satisfying the condition of 5/10,000 ⁇ S2/S1 ⁇ 5.
  • the metering nozzle 2 and the ejecting side nozzle 1 are independently provided and the minimum distance d therebetween is limited to the afore-mentioned range, natural mixing of the transparent solvent 4 and the ink 6 in the stand-by condition can be surely prevented without provision of complicated mechanisms such as one-way valve.
  • the application of voltage to the pressure-applying means provided on the metering side is interrupted, and a driving pulse is applied to another pressure-applying means provided on the ejecting side, so that the inner pressure in the ejecting nozzle 2 is lowered to a negative pressure while the inner pressure in the ejecting nozzle is raised.
  • the ink 6 is separated from the fluid mixture 10 composed of the ink 6 and the transparent solvent 4 and returned into the metering nozzle 2 so that the meniscus of the ink 6 is retracted to a position inside the metering nozzle 2, as shown in Fig. 4C.
  • the fluid mixture separated from the ink 6 projects outwardly from the discharge opening 1a of the ejecting nozzle 1, as shown in Fig. 4C.
  • the ejecting nozzle 15 has, at one end thereof, a discharge opening 15a serving as a diluent orifice and, at the other end thereof, a supply opening 15b into which the transparent solvent 4 as a diluent is introduced through the diluent feed passage 5 in the same manner as described in the afore-mentioned Embodiment 1.
  • This embodiment shows a printing device which is a combination of the end-face type having no orifice plate, and the non-premixing type having a plurality of metering nozzles.
  • the afore-mentioned channel 34 is in the form of a droplet when viewed in top plan and has a relatively wide portion serving as the diluent feed passage 32 and a relatively narrow portion serving as the ejecting nozzle 33 and gradually tapered in width toward an open end thereof.
  • a primary surface 71a of a base plate 71 is grooved to form a first channel 74 which defines a diluent feed passage 72 for the transparent solvent as a diluent and an ejecting nozzle 73 communicated with the diluent feed passage 72, a second channel 77 which defines a first ink feed passage 75 and a first metering nozzle 76 communicated with the first ink feed passage 75, and a third channel 80 which defines a second ink feed passage 78 and a second metering nozzle 79 communicated with the second ink passage 78.
  • the first channel 74 is so arranged as to be interposed between the second and third channels 77 and 80.
  • the first to third channels are covered with an oscillation plate 81 adhered onto the primary surface 71a of the base plate 71 to finally define the respective ink feed and diluent feed passages and the ejecting and metering nozzles.
  • the base plate 71 is further provided, on a back surface 71b thereof opposite to the primary surface 71a, with a fourth channel 84 which defines a third ink feed passage 82 and a third metering nozzle 83 communicated with the third ink feed passage 82, and a fifth channel which defines a fourth ink feed passage 85 and a fourth metering nozzle 86 communicated with the third ink feed passage 85.
  • the fourth and fifth channels 84 and 87 on the back surface 71b are disposed in an opposed relation to the second and third channel 77 and 80 on the primary surface 71a, respectively.
  • an opening area S1 of the discharge opening of the ejecting nozzle 73 and an opening area S2 of the discharge opening of each of the first, second, third and fourth metering nozzles 76, 79, 83 and 86 are so determined as to satisfy the same conditions as described in the afore-mentioned Embodiment 1.
  • the discharge openings of the ejecting nozzle 73 and the first, second, third and fourth metering nozzles 76, 79, 83 and 86 may have various shapes as described in the preceding embodiments, though there is some limitation due to the fact that they must be defined by the respective channels and the diaphragms 81 and 88.
