An automatic analysis device comprising: a conveyance line for conveying a specimen rack accommodating a specimen container which holds a specimen a first dispensing line and a second dispensing line both arranged along the conveyance line, for allowing the specimen rack awaiting specimen dispensing at multiple locations to stand by; a biochemical analysis unit for aspirating the specimen on the first dispensing line, and for analyzing a biochemical analysis item, such as a synthetic substrate item or a latex agglutination item, for which a reaction time of a reagent and the specimen is predetermined; a clotting-time analysis unit for aspirating the specimen on the second dispensing line, and for analyzing a clotting-time item for which the reaction time of the reagent and the specimen varies depending on the specimen; and a control unit for determining a conveyance path of the specimen rack, based on the information of the reading unit, and for controlling the conveyance line; a reading unit for reading analysis request information for the specimen; wherein when a synthetic substrate item or a latex agglutination item is set to be a first test item and a clotting-time item is set to be a second test item from among the synthetic substrate item, the latex agglutination item, and the clotting-time item in blood coagulation test items, in a case where there is a measurement request for the first test item and the second test item in the same specimen rack, the control unit is adapted to determine the conveyance path of the specimen rack and to control the conveyance line so that the biochemical analysis unit measures the first test item and the clotting-time analysis unit measures the second test item, and so that the biochemical analysis unit aspirates the specimen and thereafter the clotting-time analysis unit aspirates the specimen, wherein the automatic analysis device further comprises a rack standby unit connected to the conveyance line, for allowing the specimen rack to temporarily stand by, wherein in a case where there is a measurement request for the first test item and the second test item in the same specimen rack, the control unit is adapted to convey the specimen rack to the second dispensing line in a case where the second dispensing line is vacant after the biochemical analysis unit aspirates the specimen, and wherein in a case where the second dispensing line is not vacant, the control unit is adapted to control the conveyance line such as to convey the specimen rack to the rack standby unit, and to convey the specimen rack from the rack standby unit to the second dispensing line after the second dispensing line is vacant. a conveyance line for conveying a specimen rack accommodating a specimen container which holds a specimen a first dispensing line and a second dispensing line both arranged along the conveyance line, for allowing the specimen rack awaiting specimen dispensing at multiple locations to stand by;
