PROBLEM TO BE SOLVED: To provide a quality selector for efficiently executing an internal quality inspection of a plurality of selection objects.SOLUTION: A quality selector comprises a switching mechanism capable of switching a carrying state of carrying a selection object in a locking state to a through-hole of a cylindrical drum and a dropping state of dropping the selection object of the locking state in the through-hole on the inside of the drum and a detection mechanism capable of acquiring spectroscopic information and position information on the selection object of the locking state in the through-hole in a measurement area of a predetermined range around the rotational axis of the drum, and a control device determines an internal quality of the selection object based on the spectroscopic information from the detection mechanism, and when the selection object reaches an assortment area on the downstream side around the rotational axis from the measurement area, the switching mechanism is operated in response to a determination result of the internal quality.SELECTED DRAWING: Figure 4 |
