Abstract
A recording head for an ink-jet printer has a plurality of holes disposed in a base portion of each of a plurality of ink-jet nozzles and has an ink discharging orifice disposed at an end tip of each of the ink-jet nozzles. Each of the holes has a diameter smaller than that of the ink discharging orifice. In this recording head for an ink-jet printer, when the supply of ink to a common ink chamber is interrupted, it is possible to stop the air flowed into the recording head in an intermediate portion of an intake path of the air so that the cost of running the recording head can be reduced.
