Abstract
In a method for detecting an inferior container, wherein: light beams are projected in different two directions upon a side of a transparent or a semitransparent test container while the container is rotatably driven; both of a transmitted beam which is one of the above light beams, having penetrated through the container, and a refelected beam which is the other of the above light beams, having reflected from the container are simultaneously received by a common photo-receptive surface; a composite image constructed of both of the transmitted beam and the reflected beam is projected upon this photo-receptive surface; and an inferior container is detected by means of a shadow formed in this image.
