Abstract
A liquid material is discharged in a flying mode at a high tact by moving a needle (12) at a high speed with a small-sized drive device. A liquid droplet discharge device includes a liquid chamber (51) that is communicated with a discharge opening (60), and that is supplied with the liquid material, a needle (12) having a tip that is advanced and retracted within the liquid chamber, a drive device (2) that operates the needle (12) to advance and retract, and a displacement magnifying mechanism (3), wherein liquid droplets are discharged in a flying mode from the discharge opening (60). Even number of drive devices are disposed in a left-right symmetric relation, and the displacement magnifying mechanism (3) includes an elastically deformable U-shaped member (5, 6, 7, 8, 9) having a bottom portion to which the needle (12) is coupled.
