Patent ID: 8922852

Claim:
A device for driving a plurality of actuators included in a recording head, comprising: a plurality of select data input elements to each of which a plurality of select data sets corresponding respectively to the actuators are inputted, the information for each select data set being inputted in a serial manner through a corresponding one of a plurality of signal lines the number of which is the same as the number of the select data input elements, each one of the select data sets indicating which one of a plurality of waveform signals is to be employed for a corresponding one of the actuators in a single printing cycle, each of the waveform signals indicating one of driving modes for the actuators which are different from one another; a waveform signal selector that selects, for each of the actuators, one of the waveform signals on the basis of a corresponding one of the select data sets inputted to the select data input elements; a drive signal supplier that, based on a waveform signal selected by the waveform signal selector, supplies a drive signal to each of the actuators which is driven according to the drive signal to conduct recording on a record medium; and a plurality of converters that convert the plurality of select data sets, which are inputted to the plurality of select data input elements in a serial manner, into parallel ones; wherein the number of the select data input elements is greater than the number of bits included in each of the select data sets, the number of bits included in each of the select data sets being the number capable of representing all of the waveform signals.
