ABSTRACT:
In a dispenser apparatus, after a piston is moved toward the front end side by a first piston control unit by a distance corresponding to a prescribed injection amount (Q) and an arbitrarily decided additional amount (+.alpha.)(to position B2), the piston is moved toward the rear end side by a distance corresponding to an arbitrarily decided additional amount (-.alpha.)(to position B3) in order to decrease the pressure applied to an aerobic sealing agent. Accordingly, a dispenser apparatus which can introduce an accurate amount of highly viscous liquid within a prescribed time can be provided.
