Title:
DROPLET DISCHARGE DEVICE AND DROPLET DISCHARGE METHOD
Document Type and Number:
Japanese Patent JP2015009406
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress variation in operation of a driving element.SOLUTION: A droplet discharge device includes: a liquid chamber for storing ink; a nozzle for discharging a droplet from the liquid chamber; a plurality of driving elements for changing pressure in the liquid chamber; a generation unit for generating driving voltage of the driving elements; and a modulation circuit that generates a first driving pulse to drive the driving elements from the driving voltage for each of the driving elements and applies the first driving pulse to the driving elements, and the modulation circuit generates the first driving pulse so that discharge efficiency of the droplet differs depending on length of wiring from the generation unit to the driving elements.
