Abstract
An ink-jet recording apparatus includes: a recording head including nozzles and driving elements corresponding to the nozzles respectively; a controller; and a head driving circuit connected to the controller by a first signal line, a second signal line, and a third signal line through which a clock signal including edges is transmitted, the head driving circuit connected electrically to the driving elements. Each of the driving elements jets an ink from one of the nozzles corresponding thereto by an amount corresponding to driving voltage applied from the head driving circuit. The controller repeatedly executes output processing in which pattern signals indicating patterns of the driving voltage are continuously outputted to the first signal line while being synchronized with the clock signal and selection signals are continuously outputted to the second signal line while being synchronized with the clock signal.
