AUTOMATED ANALYZER

The purpose of the present invention is to provide an automatic analyzer capable of automatically replenishing a reagent while suppressing an increase in cost or an increase in cell size. To this end, this automatic analysis device is provided with an input unit into which a first container for accommodating a liquid is input, an analysis unit for analyzing a sample, and a transfer line for transferring the first container from the input unit to the analysis unit, the analysis unit has: a measurement unit that measures a target component contained in the sample; a reagent holding unit in which a second container for accommodating a reagent is disposed; and a dispensing mechanism that sucks the reagent from the first container and discharges the reagent to the second container. 本发明的目的在于提供一种能够在抑制成本的增加或单元尺寸的大型化的同时自动补充试剂的自动分析装置。为此，本发明的自动分析装置包括收纳液体的第一容器被投入的投入部、分析试料的分析单元以及将所述第一容器从所述投入部向所述分析单元传送的传送线，所述分析单元具有进行所述试料中含有的对象成分的测定的测定部、配置有收纳试剂的第二容器的试剂架设部以及从所述第一容器吸引所述试剂并向所述第二容器排出的分注机构。
