AUTOMATED ANALYSIS DEVICE

An automatic analyzer that can re-execute bubble detection even when bubbles are detected on a liquid level and that can reduce user's work burden without cost increase is realized. The automatic analyzer includes: a liquid dispensing mechanism 15 that performs suction of a liquid; a pressure sensor 26 that measures a change of an internal pressure of a probe provided at the liquid dispensing mechanism 15; a determination section 623 that determines whether the suction of the liquid by the probe 16 is normal suction or air suction abnormality; an analysis section; a storage section 624 that stores a cumulative number of times of air suction abnormality per liquid and an allowable cumulative number for the cumulative number of times of air suction abnormality; and a controller 60 that exercises operation control over the liquid dispensing mechanism 15, the determination section 623, and the analysis section. The controller exercises control such that the cumulative number of times of air suction abnormality is updated and the updated cumulative number is stored in the storage section 624 even if the air suction abnormality occurs unconsecutively in a course of an operation of the suction of the liquid by the probe 16 in response to the number of measurement items for the same liquid, such that the planned operation of the suction is continued until the updated cumulative number reaches the allowable cumulative number, and such that a planned request for the measurement item is cancelled and the operation of the suction is started at another liquid planned next when the updated cumulative number reaches the allowable cumulative number.
