Embodiment Construction

[0068] Embodiments of the present invention will be described below with reference to the drawings.

[0069] (first embodiment)

[0070] Figures 1A-1C , 2A and 2B show the liquid jet recording head according to the first embodiment of the present invention. The outline of the groove 9 of the liquid jet recording head of this embodiment, that is, the edge portion of the orifice 5 in contact with the groove 9 is not a straight line but a zigzag shape with fine unevenness. In addition to the composition of Figures 24A-24D and Figures 25A-25C The conventional liquid jet recording heads shown are substantially the same.

[0071] The configuration of this liquid jet recording head will be briefly described below. Such as Figures 1A-1C As shown, an orifice plate 5 having a plurality of ink discharge ports 6 of the liquid jet recording head is bonded to a substrate 2 . An ink supply port 7 is opened in the substrate 2 , and a plurality of energy generating elements (heating r...

Abstract

The present invention provides a liquid discharge recording head comprising a substrate on which an energy generating element for generating liquid discharging energy is provided, and an orifice plate which is laminated with the substrate and in which a discharge port corresponding to the energy generating element is provided, and wherein a liquid droplet is discharged in a direction substantially perpendicular to surfaces of the substrate and the orifice plate, and further wherein a flow path is formed between the substrate and the orifice plate, a groove encircling the flow path is formed in the orifice plate, and edge portions of the orifice plate contacted with the groove are formed as saw-shaped portions having a number of minute indentations.

Description

technical field [0001] The present invention relates to a liquid jet recording head (jet recording head) for liquid jet recording (ink jet recording) for jetting liquid such as ink toward a recording medium and a method for manufacturing the same. Background technique [0002] As one form of a recording device that forms an image on a recording medium such as recording paper (here, whether it is meaningful or not, including characters, graphics, patterns, etc., it is called an image), it has a liquid that discharges tiny ink droplets from tiny discharge ports. Jet recording device (ink recording device). [0003] The liquid ejection recording head includes an edge ejection type that ejects ink droplets horizontally with respect to a substrate on which an energy generating element is formed, and a side ejection type that ejects ink droplets vertically with respect to the substrate. For example, Japanese Patent Laid-Open Nos. 4-10940, 4-10941, and 4-10942 disclose side jettin...
