A vacuum tank 91, a cleaning tank 72 and vacuum tank 92 for the second reagent dispensing mechanism 52, a cleaning tank 73 for the reagent stirring mechanism 53, and a cleaning liquid supply unit that supplies cleaning liquid to these cleaning tanks 70, 71, 72, and 73. 74 and a vacuum supply unit 93 for reducing the pressure inside the vacuum chambers 90 , 91 , 92 .
- the control unit 3A basically has the same configuration as the control unit 3, except that the stored first time chart and second time chart are different.
- the cleaning liquid supply unit 74 and the cleaning tanks 70, 71, 72, 73 are connected by flow paths, and solenoid valves 80, 81, 82, 83 and pumps 84 are arranged in the connecting flow paths. is provided.
- the outer surfaces thereof are washed by discharging the washing liquid to the dispensing nozzles and stirring rods in the corresponding analysis section 2A.
- the cleaning liquid discharged by the cleaning liquid supply unit 74 may be sucked by the dispensing nozzle to clean the inside of the dispensing nozzle.
- the cleaning liquid supply unit 74 may be directly connected to the channel inside the dispensing nozzle to clean the inside of the dispensing nozzle.
- the discharge operation of the cleaning liquid in the cleaning tanks 70, 71, 72, and 73 can be controlled by opening and closing the electromagnetic valves 80, 81, 82, and 83, respectively.
- the pressure from the pump 84 is used as the driving force for discharging the cleaning liquid.
- the operating principle of the pump does not matter.
- the washing liquid the water used in the analysis section may be used, or it may be separately supplied from a reagent bottle or the like.
- Vacuum chambers 90, 91, and 92 for performing vacuum drying are provided near the cleaning chambers 70, 71, and 72, respectively.
- the vacuum tanks 90, 91, 92 are connected to a vacuum supply unit 93, and like the cleaning tanks 70, 71, 72, 73, vacuum suction and stop can be controlled by opening and closing electromagnetic valves 95, 96, 97. ing.
- the structures of the vacuum chambers 90, 91, 92 and the vacuum supply unit 93 are similar to those of the cleaning chambers 70, 71, 72, 73 and the cleaning liquid supply unit 74.
- the cleaning chamber will be described as an example. The effect of the invention similar to is obtained.
- FIG. 10 is a diagram showing an analysis cycle when biochemical analysis and immunological analysis are performed simultaneously.
- the second cycle time T2 for immunological analysis is configured to be a positive integer multiple of the first cycle time T1 for biochemical analysis.
- the cleaning tank 70 discharges the cleaning liquid and cleans the specimen dispensing mechanism 50 .
- the cleaning tank 71 discharges cleaning liquid to clean the first reagent dispensing mechanism 51 .
- cleaning tank 72 discharges cleaning liquid to clean second reagent dispensing mechanism 52 .
- the cleaning tank 73 discharges cleaning liquid to clean the reagent stirring mechanism 53 .
- FIG. 11 shows a case where the cleaning operation for biochemical analysis and the cleaning operation for immunological analysis are performed in parallel at the first cycle time T1 of the first time chart.
- FIG. 12 shows a case where only the cleaning operation for biochemical analysis is performed and the cleaning operation for immunological analysis is not performed at the first cycle time T1 of the first time chart.
- the cleaning tank 72 discharges cleaning liquid to clean the second reagent dispensing mechanism 52, and the cleaning tank 73 discharges cleaning liquid to clean the reagent stirring mechanism 53. Therefore, these times are significant. The timing is determined so that it does not occur.
- the cleaning liquid is discharged, that is, the timing of using the cleaning liquid supply unit 74 is the time period 300 and the time period 301, and the timing of using the cleaning liquid supply unit 74 in the immunological analysis is the time period 300 and the time period. 302 and time period 303 .
- Time periods 300, 301, 302, and 303 are configured so as not to overlap each other. Therefore, in the biochemical analysis and the immunological analysis, it is possible to perform the required washing liquid ejection operation completely independently.
- the timing at which each of the vacuum chambers 90, 91, and 92 is used is in the second half or immediately after the timing at which the cleaning chambers 70, 71, and 72 are used. Since they are substantially the same as 71 and 72, the details are omitted.
- the time zone 300 is configured to be shared by both biochemical analysis and immunological analysis. This is because the sample dispensing mechanism 50 is used as a common analysis unit, so the same cleaning operation can be applied.
- the time period 300 may be divided or the timing may be changed so that the cleaning of the specimen dispensing mechanism 50 is used only for each analysis. In that case, as described above, it is sufficient that the time periods during which the cleaning liquid is discharged for each analysis do not overlap.
