ABSTRACT:
It is an object of the present invention to provide a multiple-syringe-pump driving apparatus having superior liquid discharging and drawing-up precision. A syringe-pump driving apparatus of the present invention is used for controlling discharge from and drawing-up into a plurality of syringe pumps interconnected in parallel. The syringe-pump driving apparatus10comprises: a syringe holder18for supporting syringes14ato14hof the plurality of syringe pumps12ato12hso as to be arranged in parallel; a plunger holder20for supporting plungers16ato16hcontained in the syringes14a-14hso as to be arranged in parallel; three or more drive screws24-1to24-3for moving the plunger holder20and the syringe holder18relative to each other in a straight line in a syringe axial direction30; and one or a plurality of motors26serving as a source of motive power for the drive screws24-1to24-3. The three or more drive screws24-1to24-3are connected to the syringe holder18or the plunger holder20at three or more driving points to transmit motive power to the syringe holder18or the plunger holder20via the three or more driving points.
