Claim Text:
1. A particle size distribution measuring device comprising: an instrument main body that is structured to measure a particle size distribution of a sample; and an interface device that is structured to receive an input from an operator to perform drive control of the instrument main body, and to receive a measurement result from the instrument main body to display the measurement result, wherein the interface device is structured to display an evaluation graph and a measurement result graph on the same screen at a same time, the evaluation graph showing a relationship between values of operational parameters to be set to measure the particle size distribution and values of evaluation parameters which are obtained by using the measurement result from the instrument main body and correspond to respective values of the operational parameters, and the measurement result graph showing the measurement result from the instrument main body; and the interface device is further structured to display in the measurement result graph, a plurality of the measurement results corresponding to respective values of the operational parameters shown in the evaluation graph.
