Abstract: It is possible to realize a sample container transfer device capable of handling a plurality of racks in which a sample container can be efficiently transferred from a preprocessing system to a carrier used in an analysis system and can be transferred to a plurality of kinds of carriers of the analysis system. A plurality of kinds of racks A and racks B is held by an empty rack holding area 330. The racks A or the racks B can be used for conveyance of specimen containers according to the application of a specimen. After a fixed number of specimen containers separated by a separation mechanism 301 according to an application are collected by stoppers 303a and 303b, the specimen containers are conveyed to a transfer start position 309 to be transferred from a holder to a rack. Accordingly, it is possible to suppress an occurrence of a state in which the rack does not have a part where no specimen is mounted.

Abstract: Provided is a specimen processing system which can contribute to space saving. The specimen processing system includes a put-in module which puts a specimen on a put-in tray in a holder, a housing module which houses the specimen from the holder in a housing tray, and a stock module which stocks the holder, in which an empty holder which is generated because the specimen is housed is directly conveyed to the put-in module without being conveyed to the stock module and is used for putting a new specimen therein.
