AUTOMATED SPECIMEN TESTING SYSTEM

When a sample rack loops in a system and is used many times in order to avoid an increase in the size system and complicating the system, a processing speed is reduced due to an intersection of transport lines. In order to avoid the intersection, a complicated mechanism such as an elevator mechanism or a robot hand mechanism is required. An empty rack transport line is arranged at a lower stage and independent of a main transport line, a fast emergency line and a reverse line. In a rack stocker, an inclined transport line connects the empty rack transport line to the rack stocker. The rack stocker is arranged between a storage module and a loading module. The rack stocker is capable of continuously supplying and collecting empty racks, while transport lines do not cross each other. It is, therefore, possible to continuously supply and collect empty racks in a simple configuration, without an increase in the size system, an intersection of transport lines and a reduction in processing capability. In addition, it is possible to provide an automated sample testing system that is highly extendable for a facility size.
