Abstract: A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma and a plurality of analyzer units for urine are arranged along a main transfer line for transferring a sample rack from a rack providing portion to a rack storage portion. A reagent bottle for inspecting liver function is contained in each reagent delivery mechanism of two analyzer units among the plurality of analyzer units for serum. When the reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for the liver function analysis item to samples can be continued by transferring a sample rack from the rack providing portion to the other analyzer unit.

Abstract: When the operation function of an automatic analyzer is allowed to use, all selection buttons respectively provided in corresponding to a plurality of operation functions being grouped are displayed on a predetermined area of a CRT display. In this case, the button corresponding to the operation function allowed to be used for a particular operator is indicated by the color representing accessible, while the button corresponding to the operation function not allowed to be used for the particular operator is indicated by the color representing not-accessible. When the button corresponding to the accessible operation function is selected, the subclass operation function screens relating to the selected operation function are displayed in a hierarchy fashion or a multi-layer fashion.

Abstract: Waiting areas for allowing a plurality of sample racks to stop and wait are provided on by-pass line in each analysis unit. Sample racks introduced from ordinary sample inlet section or emergency sample inlet section, after waiting in the waiting area, are subjected to sample pipette operation by sample pipetting device. In the ordinary mode corresponding to ordinary sample processing, all of the stop positions of the waiting areas can be utilized, however, in the emergency mode corresponding to emergency sample processing, at least one or more of the stop positions of the waiting areas is prohibited to be used so as for the sample rack coming in to skip the stop position prohibited to be used.

Abstract: An automatic analyzer has a plurality of analytical units to which analysis items are allocated. When necessity of execution of calibration or accuracy management occurs, a display block relating to an occurrence cause on a state inspection screen flickers. When a receiving button corresponding to the flickering display block is instructed, the related analysis item name and analytical unit name are displayed in the display area and calibration or accuracy management is executed.

Abstract: In an analyzing apparatus of the present invention, sample racks, in each of which a plurality of sample containers are held, are transferred from a rack feeding unit to a discrimination unit for discriminating a type of each sample container. After the discrimination unit, a plurality of analyzing units are installed along a transfer line, and pipetters of different types are provided in the respective analyzing units. The discrimination unit detects information on the length and the width of each sample container held in each sample rack by using an optical detector. A control part selects one of the analyzing units, suitable for analyzing the sample container of which type was discriminated, based on the information detected by the discrimination unit, and transfers the sample container of which type was discriminated, to a sample pipetting position in the selected analyzing unit.

Abstract: A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma, and a plurality of analyzer units for urine are arranged along a main transfer line for transferring a sample rack from a rack providing portion to a rack storage portion. A reagent bottle for inspecting liver function is contained in each reagent delivery mechanism of two analyzer units among the plurality of analyzer units for serum. When the reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for the liver function analysis item in the samples can be continued by transferring a sample rack from the rack providing portion to the other analyzer unit.

Abstract: A reagent containing device has an outer bottle holder and an inner bottle holder. The holders are rotated independently of each other. When an instruction for exchanging reagent bottles inside the reagent containing device is input, a first reagent bottle on the outer bottle holder and a second reagent bottle on the inner bottle holder relating to the same analysis item are positioned at an opening of a bottle exchanging area. Then the opening is opened by a sliding operation of a lid so that the first reagent and the second reagent bottles can be unloaded through the opening.

Abstract: A method and apparatus for separating solid supports formed of magnetic particles on which immunocomplexes are bound, from a liquid phase includes a reaction container containing a fluid in which magnetic particles having immunocomplex bound thereon are suspended. The reaction container is positioned at a flock forming station, where the fluid is subjected to an alternate current magnetic field having a temporally varying intensity by an electromagnetic. The magnetic particles are flocculated with each other due to the application of such varying magnetic field to form a multiplicity of flocks. A stronger magnetic field then is applied to the resulting contents in the reaction container by a permanent magnet. The flocks are magnetically fixed on the inner wall surface of the reaction container by the action of the stronger magnetic field.

Abstract: An analyzer for chemically analyzing biological samples delivers required reagents in a plurality of reagent bottles to reaction containers corresponding to analysis items. A reagent which becomes deteriorated by carbonic acid gas is registered in advance, and it is judged by a control device whether such a reagent bottle is loaded in the reagent containing chamber or not. If such a reagent bottle is loaded in the reagent containing chamber, a purge gas for sweeping-out air containing carbonic acid gas is supplied to the reagent containing chamber. The flow rate of the purge gas is controlled so as to be large during an initial period of analysis preparation stage and is then decreased.
