PURPOSE: Provided is a highly versatile and small-scale, automatic sample analyzer for analyzing a blood sample, a urine sample and the like, which has simplified operation mode for easy handling by doctors and nurses, and reduced size and weight, and suppressed noise and energy saving effects. CONSTITUTION: The automatic sample analyzer comprises a pipette; a pipette driving device which moves the pipette to a sample vessel present in a predetermined position so as to cause the pipette to suck up a sample from the sample vessel, and then moves the pipette to an open vessel provided in another predetermined position so as to cause the pipette to discharge the sample into the open vessel; and an analyzing section for analyzing the discharged sample, wherein the pipette driving device comprises a vertically movable main arm and an elongated guide arm cantilevered by the main arm and extending horizontally; the guide arm has a smaller flexural rigidity than the main arm; the main arm vertically moves the pipette when the sample is to be sucked up from the sample vessel, and the guide arm guides the pipette to the open vessel and then vertically moves the pipette when the sample is discharged into the open vessel. |
