摘要： PROBLEM TO BE SOLVED: To provide an inkjet recording head which can suppress harmful effects of color mixture by a relatively simple constitution although it has unevenness in water-repellent characteristic of a face surface. SOLUTION: An inhibiting means for inhibiting mixing on the face surface is set between a first nozzle array 901 processed through the water repelling treatment and a second nozzle array 902 not processed through the water repelling treatment. Ink ejected from the first nozzle array 901 and ink ejected from the second nozzle array 902 are inhibited from mixing associated with mist during recording or when a suction recovering process is carried out. Harmful effects on images caused by the color mixture or coagulation at the face surface can be suppressed accordingly. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To optimally set the flow of ink in an ink flow channel by locally increasing the flow velocity of ink in the ink flow channel corresponding to the operation conditions of an ink jet recording head. SOLUTION: When the consumption amt. of ink is increased suddenly, the supply pressure of ink in an ink supply channel is locally raised to instantaneously supply a large amt. of ink. That is, since the flow velocity of the ink in the ink supply channel is increased locally to also exert effect on the part near to a row of nozzles 3, ink flows in a common liquid chamber 4 by flow pressure locally higher than the set flow pressure of the ink supply system of a printer main body. Especially, at a time of high frequency driving, the supply of ink fitted only to the consumption of ink per a unit time can be realized and the discharge instability of ink by the high negative pressure phenomenon caused by the supply inferiority of ink or the non-discharge of ink caused thereby can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve a printing quality by setting a through hole for filling a gap of sub units on a base plate holding a first substrate with a fluid setting member to a part corresponding to the gap. SOLUTION: Heater boards 100 as an element substrate constituting sub units are fixedly bonded to a predetermined point of a base plate 300 by an adhesive applied in a predetermined thickness. Discharge energy-generating elements 101 set on the heater boards 100 are arranged adjacent to pitches set on the heater boards 100. At this time, a silicone-type sealing member as a fluid setting member is dropped and filled into a through hole corresponding to a gap part of the heater boards 100 at a rear face of the base plate 300, whereby a first substrate is obtained.

摘要： PROBLEM TO BE SOLVED: To facilitate spreading of sealer in the case of a lengthened recording head and to improve mass productivity by providing a gap at an area for covering a supporting member by a front surface plate partly protruding to an exterior. SOLUTION: A channel of a top plate 200 and a discharge energy generating element on a heater board 100 aligned on a base plate 300 are combined and connected to become a predetermined positional relationship. Gaps between an orifice plate of the plate 200, the board 100 and the plate 300 are sealed by positively feeding sealer to grooves arranged on the plate 300, thereby sealing between the plates 300 and 20 and between an end face of the board 100 and the plate 200 by capillary force generated between the gap between the respective members and the sealer. That is, the sealer 302 charged from both sides of the plate 200 is fed to the gaps between an ink supply member, the board 100 and the plate 200.
