An automatic analyser for dispensing a sample and a reagent to each of a plurality of reaction vessels to react the sample and the reagent with each other and for analyzing the concentration of a predetermined component therein, the automatic analyser comprising: a reagent storage unit that holds a reagent bottle accommodating the reagent; a two-dimensional code which is attached to any position within the automatic analyser; an image capture unit that captures images of the reagent storage unit and the two-dimensional code; an information acquisition unit that acquires coordinate position information of the two-dimensional code within the automatic analyser, coordinate position information of the reagent bottle held within the reagent storage unit, and reagent information (511, 512) of the held reagent; an image processing unit that identifies the two-dimensional code captured by the image capture unit to specify a coordinate position in the captured image of the two-dimensional code, converts a coordinate system of the captured image obtained by the image capture unit into a coordinate system of the two-dimensional code attached to the the automatic analyser on the basis of the coordinate position information of the two-dimensional code acquired by the information acquisition unit, and specifies a position of the reagent bottle on the captured image on the basis of the converted coordinate system of the captured image, the coordinate position information of the reagent bottle acquired by the information acquisition unit, and the reagent information (511, 512); and a portable terminal that includes a display unit displaying the reagent information regarding the reagent bottle at the position of the reagent bottle on the captured image which is specified by the image processing unit. a reagent storage unit that holds a reagent bottle accommodating the reagent; a two-dimensional code which is attached to any position within the automatic analyser; an image capture unit that captures images of the reagent storage unit and the two-dimensional code; an information acquisition unit that acquires coordinate position information of the two-dimensional code within the automatic analyser, coordinate position information of the reagent bottle held within the reagent storage unit, and reagent information (511, 512) of the held reagent; an image processing unit that identifies the two-dimensional code captured by the image capture unit to specify a coordinate position in the captured image of the two-dimensional code, converts a coordinate system of the captured image obtained by the image capture unit into a coordinate system of the two-dimensional code attached to the the automatic analyser on the basis of the coordinate position information of the two-dimensional code acquired by the information acquisition unit, and specifies a position of the reagent bottle on the captured image on the basis of the converted coordinate system of the captured image, the coordinate position information of the reagent bottle acquired by the information acquisition unit, and the reagent information (511, 512); and a portable terminal that includes a display unit displaying the reagent information regarding the reagent bottle at the position of the reagent bottle on the captured image which is specified by the image processing unit.
