PROBLEM TO BE SOLVED: To provide a specimen processing device capable of efficient operation, while simplifying a device constitution in comparison with hitherto. SOLUTION: This specimen processing device 1 includes a first measuring unit 2, a second measuring unit 3, a specimen conveyance unit 4 for conveying a sample rack L for holding a plurality of specimen containers T storing the specimen, an information processing unit 5, and a bar code reading part. When bar code reading is performed to one specimen container T held by the sample rack L, and the first measuring unit 2 does not execute specimen measurement, the information processing unit 5 controls the specimen conveyance unit 4 so as to supply the specimen container to the first measuring unit 2. When the first measuring unit 2 and the second measuring unit 3 are executing the specimen measurement, the information processing unit controls the specimen conveyance unit 4 and the bar code reading part so as to execute bar code reading to a specimen container other than the specimen container.
