Abstract:
1. 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: 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.
