To provide an autoanalyzer, with which the accuracy of dispensation is increased.SOLUTION: Provided is an autoanalyzer comprising: a conveyance line for conveying a specimen container that contains a specimen; a first and a second liquid level detector for detecting a liquid level in the specimen container at different positions on the conveyance line; a specimen dispensing nozzle for drawing in the liquid accommodated in the specimen container and discharging it to a reaction container; and a control unit for controlling the conveyance line, the first and second liquid level detectors and the specimen dispensing nozzle. The conveyance line conveys calibration jigs that serve as height references to the detection positions of the first and second liquid level detectors, and the control unit calculates the heights of the respective calibration jigs using the first and second liquid level detectors and calibrates a height offset using these calculated values and the actual height dimensions of the calibration jigs.SELECTED DRAWING: Figure 3 【課題】分注の精度を高めた自動分析装置を提供する。【解決手段】検体を収容した検体容器を搬送する搬送ラインと、前記搬送ライン上の異なる位置で前記検体容器内の液面を検出する第１及び第２の液面検出器と、前記検体容器に収容された液体を吸引して反応容器に吐出する検体分注ノズルと、前記搬送ライン、前記第１及び第２の液面検出器、前記検体分注ノズル、を制御する制御部と、を有する自動分析装置において、前記搬送ラインは、高さの基準となる校正治具を、前記第１及び第２の液面検出器の検出位置に搬送し、前記制御部は、前記第１及び第２の液面検出器を用いて、前記校正治具の高さをそれぞれ算出し、この算出値及び前記校正治具の実際の高さ寸法を用いて、高さのオフセットを校正する。【選択図】 図３
