Abstract
A bottle bottom inspection apparatus in which an image sensor is located above a mouth of a bottle to pick up an image of the bottle bottom and the bottle bottom is irradiated upwardly by a light source and the bottle bottom is picked up by the image sensor via the bottle mouth thereby to inspect said bottle bottom. In this case, an optical device is disposed between the light source and the bottle bottom, wherein the optical device is operated to prevent the light from the light source from being directly incident on the bottle bottom but to cause the light to be incident upwardly on the bottle bottom with a predetermined incident angle from the outside of the bottle bottom.
