An automatic analyzer using a circular type cartridge enabling centrifugation, the automatic analyzer comprising: a main body frame; a circular type cartridge accommodating housing configured to accommodate the circular type cartridge; a circular type cartridge which is installed at an upper side of the circular type cartridge accommodating housing, wherein said circular type cartridge has a centrifugation well for centrifugation of a sample, and two or more wells for testing the sample with turning around the same; a single rotation drive unit which rotates the circular type cartridge step by step by a predetermined interval or rotates the circular type cartridge at a high speed for centrifugation, and which is installed in the circular type cartridge accommodating housing; a pipette tip included in the cartridge; a tip lifting unit that is configured to move the pipette tip for testing the well upward and downward; a measurement unit which chemiluminescencely measures a reaction in the well; a Z-axis drive unit that reciprocally operates in a Z-axis direction with respect to the main body frame, wherein the Z-axis direction is arranged transverse to the X-axis direction, and wherein the tip lifting unit is mounted on the Z-axis drive unit; and a control unit which controls the rotation drive unit, the tip lifting unit, the measurement unit, and the Z-axis drive unit so as to enable an automatic immunity analysis characterized in that the tip lifting unit is further configured to pick up the pipette tip; the automatic analyzer comprises an X-axis conveying unit which reciprocally moves in the X-axis direction of forward-backward with respect to the main body frame; the control unit is configured to control the X-axis conveying unit; the measurement unit is moved to the circular type cartridge by the Z-axis drive unit in a Z-axis direction; the circular type cartridge accommodating housing is installed with respect to the X-axis conveying unit so as to be reciprocally movable in the X-axis direction by the X-axis conveying unit; and the circular type cartridge accommodating housing includes a hollow chamber which has a vacant interior so as to accommodate the circular type cartridge at an upper side thereof, a fan unit that is configured to rotate the circular type cartridge and is installed in the hollow chamber, coupled to a central hole of the circular type cartridge by being fitted into the central hole, and configured to generate forced convection at a lower side of the circular type cartridge, a heater unit which is installed around the fan unit and which is configured to supply predetermined heat so that the well at the lower side of the circular type cartridge comes into an atmosphere at a predetermined temperature, and the single rotation drive unit is configured to simultaneously operate the circular type cartridge and the fan unit. a main body frame;
