Abstract

An automatic analysis apparatus of small size which meets the needs of regional hospitals or medium- or small-sized hospitals, and which is easy to handle and simple in construction. The apparatus employs reaction vessels of the disposable type so as to substantially completely prevent a problem of cross contamination while enabling a low running cost. The automatic analysis apparatus has a transfer path for transferring and guiding reaction vessels one by one in a linear manner, a reaction vessel transfer device for successively transferring the reaction vessels to a specimen discharging position, a reagent discharging position, an optical measuring position and a reaction vessel disposal position with respective predetermined timings, a specimen discharging device adapted to discharge a predetermined amount of a specimen to the reaction vessels at a specimen discharging position, a reagent discharging device adapted to discharge a predetermined amount of a reagent corresponding to a specimen being analyzed at a reagent discharging position, a stirring device for stirring a liquid in each of the reaction vessels, an optical measuring device for optically measuring the liquid in each reaction vessel, a disposal device adapted to discard, without cleaning, the reaction vessels the optical measurements on which are finished, and a central device for analyzing the data obtained by the optical measuring device.
