Abstract:
A control device controls driving of a pulse motor to cause liquid that is sucked into a syringe in a single suction process to be discharged over a plurality of discharge processes. The control method of the control device is a method that controls driving of the pulse motor so that rotation of a ball screw for executing each discharge process starts from an identical rotational angle position relative to a slit of a coupling.
