FIG. 3 shows an embodiment of claim 1 of the present invention and shows a setting screen for the identification condition of the specimen sample. First, the type of specimen sample to be analyzed is set in the input field 301. Subsequently, the range of serial numbers of the sample racks in which that type of sample sample is set is set in the input field 302. Then, the above setting is performed for all types of specimen samples to be analyzed simultaneously. All the information set here is stored in the storage device 122 via the interface 104. After completion of the above settings, various sample samples to be analyzed simultaneously are set on the sample racks 102 having serial numbers within a predetermined range according to the set conditions. Then, the sample racks 102 are collectively set at the rack transport start position of the rack transport device 123, and a series of analysis operations is started. The sample racks 102 are sequentially transported one by one on the transport line, and first, the serial number of the rack is read by the rack number reading device 124 and sent to the computer 103 via the interface 104.

Also in this embodiment, depending on how to specify the conditions,
It is possible to analyze from one kind of specimen sample to many kinds of specimen samples.

FIG. 5 shows an embodiment useful when an ID number (hereinafter referred to as a bar code) is assigned to each sample container. A bar code is usually composed of a band representing a group of several digits. In the present embodiment, a numeric value in an arbitrary digit of this bar code information is used as the identification condition of the specimen sample. First, the digit of the barcode that is the target of identification of the sample specimen is set in the input field 501. Then, the type of the specimen sample to be analyzed is set in the input field 502, and the corresponding numerical range of the bar code digit is input field 5.
Set to 03. All the information set here is stored in the storage device 122 via the interface 104. After the above settings are completed, check the numeric value of the digit specified on the above condition setting screen among the bar code information assigned to each sample container, and distribute the sample sample of the type corresponding to that value to that sample container .. When the analysis is started after distributing the various sample specimens to the respective predetermined sample containers in this manner, the analysis is also carried out for each type of the specimen sample, and the simultaneous analysis of many kinds of specimen samples is realized. Also in this embodiment, it is possible to analyze from one kind of specimen sample to many kinds of specimen samples depending on the way of setting the conditions.

On this screen, in addition to the identification condition setting items described above, analysis items for each type of specimen sample can be registered at the same time. After setting the type and identification condition of the specimen sample to be analyzed in the input fields 601 and 602, the analysis item for the type of sample specimen is set in the input field 603. Then, all the set information is stored in the storage device 122 via the interface 104. According to the present embodiment, since the analysis item registration for each type of sample sample can be performed on the same screen as the condition setting screen for type identification, an error such as a setting error in registration information when a large number of sample samples to be analyzed is detected. Therefore, accurate and rapid simultaneous analysis of many kinds of specimen samples becomes possible. Of course, the present embodiment can be applied to the embodiments shown in FIGS. 4 and 5.

[0022]

As described above, according to the present invention,
