Abstract

PURPOSE: To provide the subject device wherein light rays having at least two kinds of wavelengths are injected to the rinds of fruits, the fruits are estimated on the basis of reflected light rays, unbalance of fruits is reduced and the selection of the fruits is possible in a shirt treating time.
CONSTITUTION: Oranges MK are placed at the leading end of a main conveyor 300 on the centerline MC at a predetermined interval, and conveyed at a predetermined speed by the conveyor 300. On the midway of the conveyor 300 there are arranged in the conveying direction successively a positional distortion detecting device 400, a dimension measuring device 500, an indication inspecting 600 and a distributing device 700 distributing oranges MK in four stages on the basis of inspected data from the rind inspection device 600. The rind inspecting device 600 injects light rays having two different kinds of wavelengths onto the rinds of fruits, and the quantities of these reflected light rays are longarithmically converted at different bases, thus fruits being estimated in a plurality of stages on the basis of the difference between both logarithmic values.
