PROBLEM TO BE SOLVED: To provide an ink jet type recorder, in a wider sense, a liquid ejection device capable of recording highly precisely even when frequency variation, etc., occur in a motor of a moving mechanism for moving a recording head. SOLUTION: A latch signal output part 101 outputs plural latch signals in synchronization with a passage timing of each passage position of a head member. A channel signal output part 103 outputs a channel signal after the set time difference following each latch signal based on a set time difference to the latch signal. A time difference correction part 104 corrects the set time difference based on the output cycle of the latch signal. A drive signal generating means 105 generates an ejection drive signal having a latch pulse waveform PS1 appearing in synchronization with the output timing of the latch single, and channel pulse waveforms PS2, PS3 appearing in synchronization with the output timing of the channel signal. |
