Patent ID: 6882422

Claim:
An inspection device of foreign matters in liquid filled in a transparent container comprising; a rotor which successively loads transparent containers filled with liquid representing inspection objects on rotatable stands arranged in order around the circumference thereof and rotates for transferring the same; motors mounted on the rotor, each of which couples to one or plural consecutive rotatable stands; an angle detector which detects rotation angle of the rotor; plural cameras which are arranged at plural positions around the circumference of the rotor so as to permit picture image taking of the transparent containers passing thereby by making use of reflection right or transmission right; a setting means which sets a predetermined rotation pattern for the respective cameras; a motor control means which specifies a motor immediately before entering into the field of view of each camera according to the detected rotation angle of the angle detector and performs the rotation control for the respective motors immediately before entering into the field of view of each camera so as to rotate the respective transparent containers loaded on the respective rotatable stands according to the predetermined rotation pattern set for each camera; a camera control means which causes each camera to take picture images of the transparent containers which enter into the field of view of each camera; and an inspection means which performs inspection of foreign matters in liquid contained in the transparent containers based on the picture images taken by each camera.
