PURPOSE:To automatically decide the exsistence of the respective values within corresponding normal ranges only with necessary terms by connecting a plurality of memories to an arithmetic control for particle detection signal. CONSTITUTION:The peak values of particle signals provided by a particle detector 1 are measured by a comparator 2 and sent to a first memory 6 through a signal generaor 3 and an arithmetic control 4 and memorized successively in the first memory 6 in accordance with the program of a read-only memory 5. After predetermined measurement of a particle suspension has been completed, the respective addresses of the first memory 6 are called in accordance with the operating sequence of the read-only memory 5 and the respective particle counts of the addresses are divided by the total particle count and then a particle-side distribution curve indicated by percentages is memorized by a second memory 7. The same measurements and operations are performed with other samples and the data of several tens of samples is memorized. Terms to be processed, number of leucocite, for instance, are selectively commanded by an input device 10 to suitably process the information of the second memory and to memorize in a fourth memory 9 with each sample. The results of processing exceeding a predetermined range are recorded by a recording device 13. |
