To provide an ink-jet printer head which has a one-input and multi- output means and can greatly suppress an increase of the number of pads due to an increase of the number of nozzles.
The ink-jet printer head has nozzles arranged in many rows and columns, many actuators formed respectively to many nozzles, and many solenoid switches for respectively electrically controlling many actuators. The ink-jet printer head includes a first input terminal for inputting a first signal, many second input terminals for inputting second signals, a one-input and multi- output means for sequentially outputting third signals via many output terminals in response to the first signal inputted via the first input terminal, and an ink-jet driving means which controls corresponding solenoid switches thereby driving the actuators to jet ink from the nozzles when the second signals are applied via many second input terminals and the third signals are sequentially outputted in response to the first signal.
