Abstract
An inkjet printer includes a recording head having nozzles to discharge ink and a storage chamber for storing the ink which is supplied to the nozzles from an ink source. The chamber includes an inlet to which the ink flows from the ink source and an outlet from which the ink flows out to the nozzles, two walls opposite to each other and parallel to a flow direction of the ink flowing to the outlet from the inlet, and an annular rim formed along edges of the two walls. The chamber includes a pair of ribs for adjusting an ink flow, which are provided in one of the walls, protrude from the one towards the other, and extend parallel to the flow direction apart from the other. The other wall has flexibility and the ribs are spaced from the rim inside the rim.
Claims16
An inkjet printer comprising:
- a recording head having a plurality of nozzles to discharge an ink;
- and
- a storage chamber for transiently storing said ink which is supplied to said plurality of nozzles from an ink source,
- wherein said storage chamber includes:
- an inlet to which said ink flows from said ink source and an outlet from which said ink flows out to said nozzles;
- two walls opposite to each other and substantially parallel to a flow direction of said ink flowing to said outlet from said inlet;
- an annular rim formed along edges of the two walls;
- and
- a pair of ribs for adjusting an ink flow, which are provided in one wall of said two walls, protrude from the one wall towards the other wall, and extend substantially parallel to said flow direction apart from the other wall,
- wherein said other wall has a flexibility with respect to a pressure variation generated in said ink, and
- said pair of ribs are spaced from said rim inside said rim.

- and
- a pair of ribs for adjusting the ink flow which are installed so as to protrude from one wall of said pair of walls towards the other wall and extend substantially parallel to said flow direction apart from the other wall,
- wherein said other wall has a flexibility with respect to a pressure variation generated in said ink,
- the respective ribs are disposed between the other rib and said rim,
- a gap is provided between each of ends in said flow direction of said pair of ribs and an inner circumference of said rim, and
- a space between said pair of ribs linking through the gap to a space between the respective ribs and said rim.
