LIQUID JETTING DEVICE, PRINTER, AND DRIVING METHOD FOR LIQUID JETTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid jetting device, suppressing change in the drive signal simply and certainly in a constitution of a liquid jetting head by arranging a plurality of head units so that nozzles at the ends in the nozzle string direction of adjacent head units are overlapping with each other. SOLUTION: The difference in the low-pass filter characteristics between the adjacent head units 12 is reduced by setting the liquid jetting nozzle in the overlapping part so that the difference in the total number of liquid jetting nozzles of adjacent head units 12 is reduced, or the difference in the low-pass filter characteristics between the head units 12 is reduced by allowing the adjacent head units 12 to bear the liquid jetting nozzle in the overlapping part and thereby nullifying the total number of liquid jetting nozzles of the head units 12, and thereby a characteristics change of drive signal COM is suppressed or precluded.
