Abstract:
1. A method for discharging a liquid material by a discharging apparatus having a liquid chamber communicating with a discharge orifice, and a plunger which advances and retracts within the liquid chamber, capable of moving a work and the discharge orifice relative to each other and discharging the liquid material in the state of a liquid droplet through the discharge orifice, the method comprising the steps of: obtaining a distance A from a lower end of the discharge orifice to a lower end of a droplet of the liquid material discharged from the discharge orifice by a single advancing movement of the plunger, at the time when the liquid material discharged separates as a single droplet from the discharge orifice; determining a distance B between the lower end of the discharge orifice and a work surface based on the distance A to make the distance B approximately the same as the distance A; and discharging the liquid material by advancing the plunger while holding the distance B, thereby forming a dot of the liquid material, whose amount is substantially equal to that of the single droplet, on the work.
