AUTOMATIC ANALYSIS DEVICE

Disclosed is an automatic analysis device that enables easy selection of a desired reagent-setting position and efficient execution of reagent information confirmation and reagent usage setup, by displaying, at a high level of visibility and in an enlarged format, both of the selected reagent-setting position and means for moving, for example, a mouse pointer to an anterior or posterior display position with respect to the selected reagent-setting position. A display controller 312A displays a list of reagent-setting positions provided in a reagent disk 301. An extended display controller 312A1 displays, in an enlarged format, a reagent-setting position that has been selected from the reagent-setting position list displayed by the display controller, the display of the selected reagent-setting position being enlarged distinctly from that of other reagent-setting positions. A movement controller 312A2 selects a reagent-setting position displayed next to the reagent-setting position being displayed in the enlarged format.
