Abstract

A signal processing circuit uses gate signals corresponding to a plurality of divided measurement ranges to extract a fine particle pulse signal from a light reception level signal generated by an optical pickup, count the pulse number for each of the gate signals, and output a count value for each of the divided measurement ranges. A count value in-plane distribution generating unit generates count value in-plane distribution data in a measurement range based on the count value. A reaction region position coordinate computation unit estimates positions of all reaction regions from the count value in-plane distribution data. A reaction region count value computation unit calculates the count values for each of all the estimated reaction regions.
