Abstract:
A method and an apparatus of adjusting a discharge quantity of a liquid droplet with accuracy. When a plunger moves forward and stops sliding while closely contacting with an inner wall face of a tube, a discharge quantity of the liquid droplet discharged from a discharge port communicating with the tube is adjusted. A moving speed of the plunger is adjusted such that the liquid droplet discharged from the discharge port becomes constant at every discharge. The apparatus for discharging a liquid material, has a tube, a plunger sliding while closely contacting with an inner wall face of the tube, a discharge port communicating with the tube and discharging the liquid material so as to be scattered, and a control means controlling an operation of the plunger. The control means controls a moving speed of the plunger moving forward from start of deceleration to stop.
