Problems solved by technology
[0013] In the case of an inkjet head that ejects a plurality of different colors of ink, that is, when the colors of the inks that are communicated by the common ink supply passage 7 of the inkjet head are different, sometimes the ink in two adjacent common ink supply passages 7 will be separated. mix with each other, thus making it difficult to maintain the inkjet head at a predetermined level in terms of image quality
[0014] Also, in the case where the inkjet head is composed of a single substrate 1 and the structural parts are bonded to the substrate 1 and has a plurality of rows of ink ejection holes (ports) that eject ink of the same color, from the ink ejection holes (port) The amount of ink ejected can also sometimes become uneven, resulting in low-quality images produced by the inkjet head

Embodiment Construction
[0029] The present invention relates to an inkjet recording cartridge manufactured by a manufacturing method capable of preventing deformation of a substrate of an inkjet head chip or separation from an inkjet head chip supporting portion of an ink cartridge case (housing) by Different adhesives and different bonding methods are used depending on which part of the substrate of the head chip is to be fixed to the head chip support, so as to practically eliminate (or minimize) Stress that occurs in the head chip and the head chip support due to the difference in linear expansion coefficient between the head chip support.
[0030] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
[0031] The inkjet recording cartridge 10 shown in FIGS. 1 and 2 includes an inkjet recording head chip 1 (hereinafter, simply referred to as an inkjet head chip) constituted by a substrate 11 and a liquid passage forming plate 8 ...

An ink jet head includes a recording element substrate includes a plurality of ink supply ports and a supply port partition between adjacent ink supply ports; a substrate supporting portion supporting the recording element substrate at a back side thereof, the substrate supporting portion including ink supply passages corresponding to the ink supply ports and a supply passage partition corresponding to the supply port partition; a sealing material contacted to a side surface of the recording element substrate and to the substrate supporting portion; adhesive material fixing the opening partition and the supply passage partition to each other, wherein back sides of opposite ends of the recording element substrate with respect to an arranging direction of the ink supply ports are unfixed bythe adhesive material to the substrate supporting portion.
Description
technical field [0001] The present invention relates to an ink jet recording cartridge (ink jet printing cartridge) that ejects liquid such as ink from its ejection port. Background technique [0002] In the case of the ink cartridge of the inkjet recording apparatus according to the prior art, the inkjet head chip is firmly bonded to the inkjet head chip supporting portion of the cartridge case (housing) only through the back surface of its substrate, having ink ejection holes ( 口) a structural element is formed on the substrate (Japanese Patent Application Laid-Open Nos. 2000-218803 and 2001-150680). Fig. 9 is a schematic sectional view of an inkjet head according to the related art. In the case of the inkjet head shown in FIG. 9 , the inkjet head is fixed to the inkjet head chip supporting portion 2 (hereinafter referred to as the head supporting portion 2 ) through the back surface of the substrate 1 thereof using a small amount of adhesive 3 . In other words, the adhes...
