Claim Text:
1. A particle analytical device comprising a light irradiation part that irradiates the light toward a particle group that moves in a dispersion medium, a light receiving part that receives the scattered light emitted from the particle group on which the light from the light irradiation part is irradiated and that outputs an electric current signal, a data processing part that processes data concerning particle analysis based on time series data of a number of pulses obtained by the electric current signal output by the light receiving part, an overcurrent detecting part that detects flowing of an overcurrent in the light receiving part based on the electric current signal output by the light receiving part, and a control part that halts an operation of the light receiving part in a case where the overcurrent detecting part detects the overcurrent, and that restarts the operation of the light receiving part after a predetermined time passes from a time when the operation of the light receiving part is halted, wherein the data processing part holds the time series data until the halt at a time when the operation of the light receiving part is halted and processes the data, after the operation of the light receiving part is restarted, by the use of the held time series data and the time series data obtained after the restart.
