要約
(EN) The purpose of the present invention is to provide an inkjet head, and the like, for which it is possible to separate an ink chamber in a highly accurate manner by means of a simple configuration. This inkjet head 1 is equipped with: a head chip 2 hav - ing a plurality of nozzles 11, a plurality of pressure chambers 311 that respectively communicate with the plurality of nozzles 11, and piezoelectric elements 42 that cause pressure changes inside the plurality of pressure chambers 311 so as to eject ink; an ink chamber 3 for storing ink; and a retainer 90 joined to an ink supply opening formation surface 600 of the head chip 2 and retaining the ink chamber 3. The inkjet head is characterized in that: the retainer 90 has an outer peripheral wall retaining part 90a for retaining the outer peripheral wall 3a of the ink chamber 3 and a dividing wall retaining part 90b for retaining a dividing wall 3b of the ink chamber 3; and the ink chamber 3 is divided into multiple compartments by the dividing wall 3b and the dividing wall retaining part 90b.
(FR) La présente invention vise à fournir une tête à jet d'encre et analogue, pour laquelle il est possible de séparer une chambre d'encre avec une grande précision au moyen d'une configuration simple. Cette tête à jet d'encre 1 comprend : une puce de tête 2 ayant une pluralité de buses 11, une pluralité de chambres de pression 311 qui communiquent respectivement avec la pluralité de buses 11, et des éléments piézoélectriques 42 qui entraînent des changements de pression à l'intérieur de la pluralité de chambres de pression 311 pour éjecter de l'encre ; une chambre d'encre 3 pour stocker l'encre ; et un dispositif de retenue 90 relié à une surface de formation d'ouverture d'alimentation en encre 600 de la puce de tête 2 et retenant la chambre d'encre 3. La tête à jet d'encre est caractérisée par le fait que : le dispositif de retenue 90 a une partie de retenue de paroi périphérique externe 90a pour retenir la paroi périphérique externe 3a de la chambre d'encre 3 et une partie de retenue de cloison 90b pour retenir une cloison 3b de la chambre d'encre 3 ; et la chambre d'encre 3 est divisée en multiples compartiments par la cloison 3b et la partie de retenue de cloison 90b.
