Title:

AUTOMATIC ANALYZER

Document Type and Number:

WIPO Patent Application WO/2002/059624

Kind Code:

A1

Abstract:

A reagent dispensing mechanism (15) using an XY-mechanism, first and second dispensation mechanism transfer means (26, 27), and a second reagent vessel (reagent cassette) carry-in/out mechanism (24) are arranged to travel above a reagent table (25) to carry in/out a reagent cassette (22). As compared with the case where the reagent cassette carry-in/out means (24) is installed radially of the reagent table (25), the area of the automatic analyzer as seen in the horizontal direction can be reduced and the movement of the reagent vessel (16) to a predetermined position can be effected in a shorter time by combining the rotation of the reagent table (25) with the movement of the XY-mechanism. Further, as compared with the case where reagent dispensation is effected by using the reagent dispensation transfer mechanism with respect to reagent vessels in a matrix pattern, the travel distance of the transfer mechanism can be shortened and so can be the travel time, so that the analyzer corresponds to a machine of high processing capability with reduced cycle time.
