PROBLEM TO BE SOLVED: To provide an automatic liquid agent mixing device having good maintainability.SOLUTION: An automatic liquid agent mixing device 1 includes a liquid agent tank 10, liquid agent supply flow passages 3, liquid agent force-feeding means 4, suction flow passage changeover means 5, and a control part 6. The control part 6 controls the suction flow passage changeover means 5 interlockingly with piston drive parts 40 such that a first suction flow passage 31 is opened and a second suction flow passage 32 is closed when a first syringe 4A performs a suction step, and that the second flow passage 32 is opened and the first suction flow passage 31 is closed when a second syringe 4B performs the suction step. |
