PURPOSE:To use a data processing part in common, by providing ROM, in which each processing program is stored, to each of various kinds of analytical machineries and transmitting the content of ROM to the memory of the data processing part at the time of connection. CONSTITUTION:A data processing part 1 has CPU9, internal memory 10, up-load memories 12A-12C for analyzers and interfaces 11A-11C. One analyser 2A has a microprocessor 13, RAM memory 14, ROM15, an analytical part 16, a control circuit 17 and an I/O port 18. The processing program in ROM15 is transmitted to the up-load memory 12A by the order from the data processing part 1. The data processing part 1 performs the data processing of said analyser on the basis of said program. Because a general-purpose property is provided, the data processing part can be used in common and cost is conserved.
