AUTOMATED ANALYZER

This automatic analyzer is provided with: a water supply tank (53); a supply flow path (70) connected from the water supply tank (53) to each mechanism of the automatic analysis device (100); a water supply pump (54) for supplying water from the water supply tank (53) to each mechanism via a supply flow path (70); a detector (61) that detects an abnormality in the supply flow path (70); a waste liquid flow path (63) branching from the supply flow path (70) at a branching pipe (60) provided in the supply flow path (70); a relief valve (62) provided in the waste liquid flow path (63); and a control unit (64) for controlling the operation of each mechanism in the automatic analysis device (100). The control unit (64) opens the relief valve (62) while driving the water supply pump (54) on the basis of the abnormality of the supply flow path (70) detected by the detector (61). As a result, an automatic analysis device that does not require manual discharge of air in the pump is provided. 本发明的自动分析装置包括：供水箱(53)；从供水箱(
