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: With the increase in the speed of operation of a device, it is necessary to perform washing to drying for a wide range of a probe in a short time. A probe, a washing nozzle which ejects a washing liquid, a vacuum nozzle which sucks air, a washing tank, which is connected to the washing nozzle and the vacuum nozzle, and in which washing and drying of the probe is performed by ejecting the washing liquid from the washing nozzle and then sucking air by the vacuum nozzle, a waste liquid flow path, which is connected to the washing tank, and into which the washing liquid is discharged, and a shielding member 100 which shields a flow path between the washing tank and the waste liquid flow path after the washing liquid is ejected from the washing nozzle.

Abstract: An automatic analyzer is capable of ensuring sufficient nozzle cleaning and suppressing of deterioration in the accuracy of analysis. When it is judged that there remains no analysis item of the sample, a judgment is made on whether the sample dispensation quantity of the n-th sample dispensation is less than a dispensation quantity threshold value or not, and if less, a cleaning pattern is selected by making a judgment on whether or not all the sample dispensation quantities of the first through (n−1)-th sample dispensations are less than the dispensation quantity threshold value. If the sample dispensation quantity of the n-th sample dispensation is the dispensation quantity threshold value or more, another cleaning pattern selected by making the judgment on whether or not all the sample dispensation quantities of the first through (n−1)-th sample dispensations are less than the dispensation quantity threshold value.

Abstract translation: 自动分析仪能够确保足够的喷嘴清洁和抑制分析精度的劣化。 当判断不存在样品的分析项目时，判断第n个样品分配的样品分配量是否小于分注量阈值，如果更少，则清洁图案是 通过判断第一至第（n-1）个样品分配的所有样品分配量是否小于分配量阈值来选择。 如果第n个样品分配的样品分配量是分配量阈值以上，则通过对第1〜第（n-1）个样品的全部样品分注量进行判断而选择的另一清洗图案 分配量小于分配量阈值。
