<p>PROBLEM TO BE SOLVED: To provide an opening inspection device of a glass bottle that can improve the inspection accuracy and can be downsized.SOLUTION: The opening inspection device includes: a rotation mechanism for rotating a glass bottle 11; a projector 21 for radiating light to an opening 11d of the rotating glass bottle 11 from the obliquely lower side; and a line sensor camera 22 for detecting a defect in the range from the top surface 19c to a skirt 19b by detecting the light having passed through the wall surface of the opening 11d of the glass bottle 11. The line sensor camera 22 has a gate angleθ2, and focuses on the longitudinal whole region of the opening 11d of the glass bottle 11, thereby detecting the defect.</p> |
