Abstract
The liquid discharging device includes a driving mechanism that drives a needle, a measurement plunger member and an inlet valve member that are concentrically-arranged inside a container. The driving mechanism includes: a piezoelectric-element support plate to which piezoelectric elements are attached; a spring for biasing the piezoelectric-element support plate toward a discharge outlet; and a control device adapted to control the piezoelectric elements separately. The piezoelectric-element support plate includes: a base end to which first end sides of the piezoelectric elements are fixed; a drive unit to which second end sides of the piezoelectric elements are fixed; and a displacement expanding portion expanding and outputting a displacement of the drive unit, the drive unit being displaced in conjunction with a expansion and contraction driving of the piezoelectric elements. Since the three members can be driven by the two piezoelectric elements, a driving at high speed can be realized and the liquid discharging device can be easily downsized.
