Abstract
An object of the present invention is to provide a dispensing device capable of preventing bubbles from jumping out of a nozzle and realizing highly accurate dispensing even though the nozzle is moved at a high speed toward a liquid level and is decelerated and stopped at a high acceleration. The dispensing device according to the present invention starts suction of a liquid in a period from when a nozzle starts to be lowered toward a liquid level of the liquid to when an end portion of the nozzle comes into contact with the liquid level of the liquid and the lowering of the nozzle is stopped (see FIG. 6).
