Patent ID: 7568776

Claim:
A recording apparatus comprising: a recording head that performs dot recording and has a plurality of actuators; a drive circuit that outputs drive pulses to the plurality of actuators of the recording head; and a signal transmission circuit that serially transmits, to the drive circuit, a serial signal for generating a plurality of recording waveform signals for the dot recording, and selection data on a selection signal for each actuator, for selecting a predetermined recording waveform signal from the plurality of recording waveform signals, wherein the drive circuit includes: a serial-parallel converting circuit that parallely converts the serial signal transmitted from the signal transmission circuit so as to generate the plurality of recording waveform signals; and a selecting unit comprising a plurality of selectors connected to the serial-parallel converting circuit through a plurality of signal lines, respectively, the plurality of signal lines corresponding to the plurality of recording waveform signals, respectively, wherein each of the plurality of selectors selects, based on the selection signal, a predetermined recording waveform signal from the plurality of the recording waveform signals independently of each other selector, and the drive circuit outputs the recording waveform signal selected by each selector, and wherein the serial-parallel converting circuit parallely converts the serial signal corresponding to each of clock pulses of a clock signal transmitted from the signal transmission circuit, into parallel signals corresponding to the plurality of recording waveform signals, and the serial-parallel converting circuit outputs the plurality of parallel recording waveform signals based on a latching signal outputted from the signal transmission circuit, and wherein each of the recording waveform signals contains one or more drive pulses, and the serial signal contains a state of the one or more drive pulses of each of the recording waveform signals, in serial, for each group of a constant number of clock pulses, and wherein in the serial signal, the plurality of the recording waveform signals that are divided based on the clock signal along a time series, are aligned along the time senses.
