To provide a sample carrier system suitable for the constitution, wherein the large scale of the system can be avoided even if the number of the samples and the number of processing devices are increased.

A sample 1 is divided by a sample dividing device 14 and mounted on a sample supporting body having a recording medium part, which is readable and writable in correspondence with the contents of the inspection. The sample is carried by a carrier line 32. At first, the carried sample 1 obtains the inspection information data from an information system based on the read- out data by a label-reader 34 for reading the label attached to the sample 1. The data are written into the above described record medium part of the above described sample supporting body by an inspection-information writing device 35. The above described sample supporting body, wherein the inspection information is written, is carried to a plurality of sample processing part 5 by the carrier line 32. In each sample processing part, the inspection information of the above described record medium part is read out with an inspection- information reading device 36, and the specified processing is performed based on the information. The result is written into the above described record medium part by the inspection-information writing device 35.
