Patent ID: 7210756

Claim:
A driving apparatus for at least one recording head, the apparatus comprising: a first waveform signal receiver that receives, through signal lines, a plurality of waveform signals representing various recording modes; a first drive signal provider that generates drive signals on the basis of the plurality of waveform signals received by the first waveform signal receiver, and supplies the drive signals to one of recording element groups included in the at least one recording head: a first delay circuit that delays the waveform signals received by the first waveform signal receiver; and a second drive signal provider that generates drive signals on the basis of the waveform signals delayed by the first delay circuit, and supplies the drive signals to another recording element group; wherein the apparatus further comprises a second waveform signal receiver that receives, through signal lines, a plurality of waveform signals representing various recording modes; and wherein the first delay circuit selectively outputs, to the second drive signal provider, either the waveform signals obtained by delaying the waveform signals received by the first waveform signal receiver or the waveform signals received by the second waveform signal receiver.
