PURPOSE:To ensure various-type operation of a point depositing means to point- deposit sample liquid on a chemical snalysis slide in a simple mechanism. CONSTITUTION:Sample liquid is sucked from a sample cup 26 into a nozzle tip 25 mounted at the end of a point depositing nozzle 91 and then moved to a point depositing section 13 to point-deposit a preset amount of sample liquid on the reagent layer of a chemical analysis slide 11. After point deposition, the optical concentration of the chemical analysis slide is measured to find the concentration of biochemical material in the sample liquid. On the other hand, the nozzle tip after used is removed at a tip removing section 20 and time point depositing nozzle is pressurized at the end while being thrusted by the pad member 24 of a leak checking section 21 for leak check. In such a case, the point depositing nozzle 91 is given swinging drive in a preset circular arc, where the unused nozzle tip 25. the sample cup 26, the point depositing section 13, the tip removing section 20 and the leak checking section 21 are arranged. |
