ABSTRACT:
A check detector is provided for the neck and finished portions of a bottle which comprises a rotating means which is capable of rotating an inspection bottle; a plurality of emitters and a plurality of receivers arranged on an approximately hemispherical fixture arranged around the neck and finished portions of an inspected bottle as a center; means for obtaining N.times.M data per single scan against the inspected bottle, wherein N is a number of emitters, and M is a number of receivers; means for assorting the data obtained; and means for differentiating the data. Setting of job change depending on bottle types can be conducted automatically, and detecting checks in the neck and finished portions of a bottle can be conducted overall with no relation to the portion and type of defects. Detecting of a bubble, a contaminant, a chipped and unfilled thread and deformation which are known defects in the neck and finished portions of a bottle can be achieved. Further, assorting defects into both portions and type can be achieved to improve the quality control.
