Abstract
An automatic immunoassay analyzer includes first and second conveyors which support a plurality of speciment vessels and reaction vessels, respectively. Both conveyors are rotated synchronously and continuously in the same direction by first and second conveyor driving devices. A division-pouring device sucks a speciment from a speciemen vessel stopped at a suction stage and pours a portion thereof into a reaction vessel stopped at a division-pouring stage. A holding device stops and holds one of the specimen vessels transferred into the suction stage for a predetermined time period in which the reaction vessel(s) holding measurement analytes to be tested for the respective specimen are transferred and stopped sequentially at the division-pouring stage. The analyzer reduces operator error, and ensures alignment of the reaction vessels with the appropriate specimen to be tested.
