It has the function which can be implemented as a feature.

  According to the present invention, various error mistakes can be easily solved at once.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram of the overall configuration of the automatic analyzer.

  The automatic analyzer includes an operation unit 101 having an interface 106, an analysis unit 108, a storage device 107, a printing device 105 for printing data, and the like.

  The operation unit 101 includes a computer having a display device 104 for displaying data, a keyboard 102 and a mouse 103 for inputting data.

  The storage device 107 is connected to the analysis unit via the computer and stores analysis instruction information, measurement results, and various information.

  The analysis unit 108 connected to the operation unit 101 via the interface 106 has a reaction disk 109. A plurality of reaction vessels 110 are installed on the concentric circumference of the reaction disk 109. On the concentric circumference of the reagent disk 111, a plurality of reagent bottles 112 containing various reagents are installed.

  Around the reaction disk 109, a specimen dispensing probe (dispensing mechanism) 113, a stirring device 114, a cleaning device 115, a light source 116, and a multi-wavelength photometer 117 are arranged.

  A reagent dispensing probe (dispensing mechanism) 118 is disposed between the reaction disk 109 and the reagent disk 111.

  A rack transport belt 119 is installed on the rotation circumference of the sample dispensing probe (dispensing mechanism) 113. The rack 120 moves on the rack transport belt 119. A plurality of specimen containers 121 containing specimens are installed in the rack 120.

  All of these mechanism operations are controlled by the computer 123 via the interface 122.

  The operator gives an analysis instruction to the analysis device using the display device 104 of the operation unit 101, the keyboard 102, or the mouse 103. The analysis instruction is stored in the storage device 107 and is transmitted to the analysis unit 108 via the interface 106.

  The analysis unit 108 performs the analysis operation as follows in accordance with the received analysis instruction.

  A sample dispensing probe (dispensing mechanism) 113 dispenses a predetermined amount of the sample contained in the sample container 121 into the reaction container 110.

  When the dispensing of one sample container 121 is completed, the rack transport belt 119 moves the rack 120 so that the next sample container 121 is directly below the sample dispensing probe (dispensing mechanism) 113.

  When the dispensing of all the sample containers 121 on the rack 120 is completed, the rack 120 is carried out by the rack transport belt 119. The reaction container 110 into which the sample is dispensed rotates on the reaction disk 109 by the rotation operation of the reaction disk 109.
