Document Type and Number:
Japanese Patent JP2017064922
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid discharge device that can maintain a potential of liquid at a constant potential while being suppressed from being enlarged in size.SOLUTION: Annular conductors 45 that surround through-holes 29 of a piezoelectric actuator are provided on a surface at the opposite side of a flow path substrate 21, of the piezoelectric actuator. To the piezoelectric actuator is jointed, via the annular conductors 45, a reservoir forming member 23 having a supply flow path communicating with the through-holes 29 formed. The annular conductors 45 are kept at a predetermined constant potential and exposed to flow paths in the through-holes 29.SELECTED DRAWING: Figure 3
