Controller of an optical sorter is configured to receive an input of a candidate for a target quality condition regarding an allowable mix rate of defective products in sorting targets discharged from the optical sorter as acceptable products, receive an input of quality information indicating a mix rate of the defective products regarding at least a part of the sorting targets, simulate, based on the information, a sorting result regarding a quantity and/or a yield of the sorting targets discharged as the acceptable products that is expected to be acquired when sorting is conducted by a sorting device to achieve the candidate for the target quality condition and output a result of the simulation, receive an input of a final target quality condition to be employed when conducting the sorting, and conduct the sorting based on a sorting control parameter that allows the final target quality condition to be achieved.

A piezoelectric valve, having superior responsiveness during valve opening and capability to stabilize gas supply at an early stage, includes a gas pressure chamber receiving compressed gas and an exhaust path discharging the compressed gas from the gas pressure chamber; a valve disc placed in the gas pressure chamber to open and close the exhaust path; a piezoelectric element generating a driving force for operation of the valve disc, as a displacement; a displacement magnifying mechanism magnifying the displacement of the piezoelectric element and applying the magnified displacement to the valve disc; and driving means including a signal generator generating a signal including a first prepulse, a second prepulse, and a main pulse, applies a drive voltage to the piezoelectric element using the signal generated by the signal generator, as an input signal to a drive circuit, and drives and opens the valve disc by expanding the piezoelectric element.
