Method of conveying sample rack and automated analyzer in which sample rack is conveyed

摘要

When a sample rack holding a sample is conveyed by using a conveyance line to be analyzed by one of a plurality of analysis units, the sample rack is efficiently conveyed without being disturbed by other sample racks. When the sample rack is detected at a transmission port 10 of a rack supplying unit 3 or transmission port 18a or 18b of an analysis unit, a conveyance request is sent to a controller. The controller selects a path adapted to the sample rack from a plurality of conveyance paths and counts waiting time. When the conveyance is permitted, the sample rack is carried by a main conveyance line in a state where no other sample racks exist and is sent to a selected reception port. When there are a plurality of sample racks waiting to be conveyed, the sample rack having loner waiting time is preferentially conveyed.
