First Claim
1. An outer appearance quality inspection system comprising:
- (a) first means for aligning objects to be inspected;
(b) second means for transporting the aligned objects;
(c) third means for illuminating a light within a predetermined wavelength range against the objects being transported.(d) fourth means for receiving the light reflected from each of said objects so as to convert the light into an electrical signal;
(e) fifth means for detecting macro visible damage of said object in response to the electrical signal derived from said fourth means;
(f) sixth means for detecting micro visible damage of said object in response to the electrical signal derived from said fourth means;
(g) seventh means for producing first data determining a visible damage from the detected micro and macro visible damages;
(h) eighth means for sorting the objects being transported by said second means in response to the first data derived from said seventh means;
ninth means for producing second data representative of the size and coloring of each of said objects, said second data being applied to said eighth means so that said eighth means sorts the objects being transported by said second means in response to the first and second data;
(j) tenth means for forming an average visible light region signal from aid electrical signal;
(k) eleventh means for forming a green region signal from said electrical signal;
(l) twelfth means for obtaining a level ratio of said average visible light region signal to said green region signal;
(m) thirteenth means for obtaining a histogram of said ratio; and
(n) fourteenth means for judging coloring of said object from said histogram.

Abstract
An outer appearance quality inspection system comprising a mechanism for aligning objects to be inspected, a mechanism for transporting the aligned objects, light projectors for illuminating a light within a predetermined wavelength range against the objects being transported, light receiving devices for receiving the light reflected from each of the objects so as to convert the light into an electrical signal, an electronic circuit for obtaining the data representative of the conditions of the surfaces of the object in response to the electrical signal derived from the light receiving devices, and a mechanism for sorting the objects being transported in response to the data derived from the electronic circuit. The system can inspect the size, visible surface damages and coloring of an object such as orange automatically and reliably.
