Since the rack position / presence / absence detection unit 49 is provided in the vicinity of the lane shift unit 46, the presence of the sample rack 41 in the lane shift unit 46 can also be determined here.
  • step S21: No when there is no other sample rack on the lane of the transport line (step S21: No), the transfer control unit 40 moves the emergency sample rack to the specific analyzer's arch I in step S17. Stop at the position and enable the dispensing operation by the sample dispensing unit 6. If there is another sample rack on the lane of the transport line (step S21: Yes), this other sample rack is stopped on the bridging lane 46a of the nearby lane shift unit 46 (step S22). Then, the lane shift unit 46 is shifted to the position (dotted line in FIG. 4) where the positional force in the initial state (solid line in FIG. 4) is also shifted to the inside of the analyzer (step S23).
  • the sample rack can be retracted into the analyzer, and the lane 46a for bridging the center and outside of the analyzer can be driven in combination with the sample transport unit 44.
  • the emergency sample rack is stopped on the suction position of a specific analyzer, that is, on the bridge lane 46a of the lane shift unit 46 (Step S24), and the emergency sample rack by the sample dispensing unit 6 is stopped. Enables dispensing of the sample mounted on the.
  • the emergency sample rack is bridged to the sample transport unit 44 at the rear in the transport direction, transported to the transport line, and further to the sample recovery unit 45. Collect (step S2 6).
  • the transfer control unit 40 shifts all the lane shift units 46 on the transport line to the initial state (step S27), transports them to the transport line of the sample rack (step S28), and transports them.
  • the rack position / presence / absence detection unit 49 detects the position and presence / absence of the sample rack (step S16), thereby enabling the dispensing and transport of the sample in a specific analyzer.
  • the lane driving unit is controlled so that the sample rack retreated by the lane shift unit is shifted and quickly returned to the transport line, so that the sample rack is immediately specified from the retreated position. It can be transported to the analyzer's suction position, and the sample rack can be transported efficiently even for sample racks other than the emergency sample rack.
  • the present invention in which the sample transport unit (main lane) is configured by two lanes is not limited to this, and may be one or three or more. Further, in the embodiment, the number of bridging lanes is one more than the number of main lanes, and the power is composed of three. The present invention is not limited to this, and the lane has two or more bridging lanes than the number of main lanes. It is also possible to have a configuration with a shift unit. In this case, the number of sample racks that can be evacuated at a time by the lane shift unit increases, and the rack can be transported more efficiently.
  • the present invention is useful for an automatic analyzer that transports a sample rack holding a sample to a suction position of each analyzer via a main lane, and particularly has a high analysis priority. This is suitable for the case where the subsequent emergency sample rack is first transported.

Abstract

La présente invention concerne un analyseur automatique (1) qui possède plus de voies qu'une section de transport d'analyte (44), ainsi qu'une section de décalage de voie (46) ayant une voie de liaison (46a) pour décaler une armoire d'analyte dans une direction perpendiculaire à la direction du transport. Pour transporter d'abord une armoire d'analyte d'urgence suivante ayant une priorité supérieure d'analyse, une armoire d'analyte précédente (41) présente sur la voie de liaison (46a) est temporairement évacuée, d'une voie de transport par une opération de décalage de la section de décalage de voie (46) pour permettre à l'armoire d'analyte d'urgence suivante d'être transportée en premier.
