PROBLEM TO BE SOLVED: To obtain a conveyance system whose operability is enhanced by a constitution wherein a main conveyance route and a bypass conveyance route are provided, an empty rack which is used to convey a blood-collected blood collecting tube is fed sequentially and a rack which is loaded with a blood-collected blood collecting tube is retured sequentially to the main conveyance route from the bypass conveyance route. SOLUTION: In a conveyance means 15 for a specimen, a main conveyance route (a circulating conveyance route) 151 is arranged and installed under a blood collecting base along a pallet conveyance means 7, a bypass conveyance route 152A and a bypass conveyance route 152B are arranged and installed so as to bypass a pallet distribution place, and an empty rack is loaded with a spent blood collecting tube. A control means 11 is provided with a blood-collected-tube detecting sensor which detects whether an actuator for first route changeover at a rack and a rack on the conveyance route 151 are loaded with a spent blood collecting tube in a branch place to the bypass conveyance routes 152A, 152B from the conveyance route 151. By the signal of the sensor, the actuator for route changeover is controlled automatically. When the rack is loaded with the blood collecting tube, a branching operation is released, and the blood collecting tube is transferred to the conveyance route 151.
