Abstract: In a case where a sample container 15 has a rubber-made lid 35, if a sample nozzle descends and comes into contact with the lid, the sample nozzle is relatively moved inside an arm as far as a lid detection distance, and a detector detects a detection plate. A fact that the sample nozzle comes into contact with the lid is stored together with position information of the sample nozzle, into an operation commanding unit. The sample nozzle further continues to descend, and a suction operation of a sample is performed at a predetermined position. In a case where the sample nozzle collides with a frame portion of the lid and external force is applied thereto, the detector detects that the detection plate is relatively moved as far as the detection distance.

Abstract: The invention provides a highly reliable automatic analyzer and dispenser probe cleaning method that allows for the removal of leftover cleaning water from the outer wall surfaces of a probe without increasing the size of a cleaning bath and contaminating the outer wall surfaces of the probe. A cleaning bath 113 (108, 106) comprises: a cleaning water outlet 203 for discharging into the cleaning bath 113 (108, 116) the cleaning water supplied from a cleaning water supply mechanism 123; and a compressed air outlet 204, disposed on the trajectory of the cleaning water discharged from the cleaning water outlet 203, for discharging the compressed air supplied from a compressed air supply mechanism 124 toward a sample probe 111b or a reagent probe 120 inserted in the cleaning bath 113 (108, 106).

Abstract: To provide an automatic analyzer which is not influenced by fluidity or viscosity of a sample, and which can stably dispense the sample with dispensing accuracy by determining whether a flow route including a sample probe is in a stable and suction-available state when the sample is suctioned. In suction of the sample, before the sample is suctioned, in the flow route including the sample probe, the automatic analyzer determines whether the sample is in a suction-available state or in a suction-unavailable state, and performs cleaning on the flow route when it is determined that the sample is not in the suction-available state. Since the state in the flow route including the sample probe is determined before the sample is suctioned, the automatic analyzer can repeatedly perform a dispensing operation having improved reliability, without being influenced by the fluidity or the viscosity.

Abstract: An automated analyzer maintains high processing capacity and dispensation accuracy even when items requiring dilution/pretreatment and general reaction measurement are mixed. A plurality of sample dispensing mechanisms are independently driven and each include a sample collection position, a sample nozzle for collecting the sample, and a washing tank for washing the sample nozzle. The sample dispensing mechanisms are configured to collect the sample from a plurality of sample collection positions and are operated independently to perform sample dispensation into reaction containers on a reaction disc. At least one of the sample dispensing mechanisms is provided for each of a sample requiring dilution/pretreatment and a sample that does not require dilution/pretreatment. The automated analyzer is provided with a control means for causing the respective mechanisms to be operated in a dedicated manner. The sample is dispensed such that no vacancy is created in the reaction containers.
