ABSTRACT:
An ink jet print head comprising: a diaphragm array including a group of bending curved partitions defining a multiplicity of orderly arranged ink channels, an upper end wall bridging between upper ends of partitions and a lower end wall bridging between lower ends of the partitions; an orifice board fixed to one surface of each of the upper and lower end walls of the diaphragm array and closing one mouth of each ink channel with a slight gap with respect to the individual partitions so as to allow the individual partitions to bend, the orifice board having a multiplicity of ink jet orifices communicating with the respective ink channels; a back board fixed to the other surface of each of the upper and lower end walls of the diaphragm array and closing the other mouth of each ink channel with a slight gap with respect to the individual partitions so as to allow the individual partitions to bend, the back board having a multiplicity of ink supply inlets through which ink is to be supplied to the respective ink channels; and a piezoelectric actuator for bending the individual partitions of the diaphragm array selectively.
