An automatic analysis apparatus in which a two-dimensional code (206) is affixed to a reagent storage unit (209) at a location visible from the outside, and the coordinate position of the two-dimensional code (206) in the coordinate system of the two-dimensional code (206) and coordinate information of the positions where reagent bottles (208) are placed are held. Then, an image of the two-dimensional code (206) is captured by a portable terminal (300), and the coordinate system of an image capture unit (309) of the portable terminal (300) is converted to the coordinate system of the two-dimensional code (206) by augmented reality. On the basis of this, the coordinate information of the positions where the reagent bottles (208) are placed in the coordinate system of the two-dimensional code (206) is taken as positional coordinates in the captured image, the positions of the reagent bottles (208) in the captured image are ascertained, and the ascertained positions are displayed on a display unit (308).
