A discrete type automated chemical analytic apparatus, wherein a carrier is made movable through a path defined above a reaction line in order to pipette a specimen and reagent into the selected one of a plurality of reaction tubes linearly mounted on the top run of an endless belt. A specimen container and reagent containers are set side by side above the extension of the reaction line. Nozzles are mounted on the carrier in a vertically movable state to draw out the contents of the specimen container and reagent containers. The carrier is moved to any selected point on the reaction line by a motor with the aid of a belt conveyor connected to said carrier, and a pair of pulleys across which the belt conveyor is stretched.
