Patent ID: 7771656

Claim:
An automatic analyzer comprising: a rotatable reagent table on which a plurality of reagent vessels, each holding a reagent, are held, said reagent table including a plurality of annular reagent vessel holders holding said reagent vessels; an annular reaction table positioned adjacent said rotatable reagent table and holding a plurality of reaction vessels; a first reagent vessel carrying-in/out mechanism for lifting up one of said reagent vessels positioned at a reagent vessel movement standby position adjacent said one reagent table and for lowering said reagent vessel to a reagent vessel loading position; a reagent dispensing mechanism for sucking a reagent in from said one reagent vessel and for ejecting the reagent to one of said reaction vessels, said reagent dispensing mechanism being directly mechanically connected to said first reagent vessel carrying-in/out mechanism; first and second transfer means directly mechanically connected to each other for moving said reagent dispensing mechanism and said first reagent carrying-in/out mechanism in X and Y directions in a horizontal plane through a space above said reagent table; a control system for controlling operations of said rotatable reagent table, said reagent dispensing mechanism, said first and second transfer means and said first reagent vessel carrying-in/out mechanism; and a photometer for measuring an absorbance of a solution of a reagent and a sample mixed in said one reaction vessel.
