Patent ID: 7766439

Claim:
A recording apparatus comprising: a recording head having a plurality of actuators for performing dot printing; a drive circuit which outputs respective drive pulses to the respective actuators; and a main circuit which transmits, to the drive circuit, a drive signal for outputting the respective drive pulses to the respective actuators, wherein the drive signal transmitted by the main circuit to the drive circuit includes selection data for selecting, for each of the actuators, a drive-waveform signal which provides a waveform of each of the drive pulses to be outputted to the respective actuators, among plural sorts of drive-waveform signals, wherein the main circuit transmits, to the drive circuit, a clock signal and a drive-waveform-data signal that is a serial signal in which is included data to generate the plural sorts of drive-waveform signals, wherein the drive circuit includes a drive-waveform-signal generating circuit which generates the plural sorts of drive-waveform signals on the basis of the clock signal and the drive-waveform-data signal, wherein the drive circuit selects, for each of the actuators, one of the plural sorts of drive-waveform signals generated by the drive-waveform-signal generating circuit and outputs, to each of the actuators, the drive pulse which is based on said one of the plural sorts of drive-waveform signals selected for said each of the actuators, and wherein the drive-waveform generating circuit generates: at least one sort of first drive-waveform signal as a first part of the plural sorts of drive-waveform signals on the basis of states of the drive-waveform-data signal which correspond to rising edges of clock pulses of the clock signal; and at least one sort of second drive-waveform signal as a second part of the plural sorts of drive-waveform signals on the basis of states of the drive-waveform-data signal which correspond to falling edges of the clock pulses of the clock signal.
