Abstract
Abstract A discrete type automated chemical analytic apparatus, wherein a carrier member (70) reciprocatable in parallel with a reaction line (14) constituted by those of the reaction tubes linearly arranged on an endless belt (10) which are set on the top run (10a) of the endless belt (10) supports two reagent-pipetting nozzles (58, 59) in a vertically movable state. The corresponding reagent containers (22, 23) are disposed on an extension of the reaction line. The nozzles (58, 59) through which the reagent is sucked from the reagent containers (22, 23) pipette the sucked reagent into the corresponding reaction tubes at predetermined points on the reaction line (14) in accordance with the movement of the carrier member (70). The specimen discharge mechanism (27) includes a nozzle (34) for pipetting a specimen at a prescribed point on the reaction line (14).
