INK JET HEAD AND PRINTER

摘要

A printer having an ink jet head (110) for pressurizing pressurization regions provided in a plurality of pressure chambers to discharge the ink from nozzles in the pressure chambers, wherein an ink reservoir space (130) is defined between a head body (3) and an ink feeder (50), and the ink reservoir space (130) and each pressure chamber are put in communication with each other by an ink feed passage (129) that is opened at one end to the ink reservoir space (130) on the outer surface of the head body (3) and at the other end to each pressure chamber, whereby the ink from the ink feeder (50) can be directly fed into each pressure chamber, while achieving improved print quality by making uniform the feeding of ink into each pressure chamber, in addition to a reduction in size of the ink jet head and an improved degree of integration.
