A bottle inspection apparatus for optically inspecting the bases of transparent bottles comprises a light source disposed below the inspection position through which a line of bottles is fed and a photocell device disposed above the position for scanning the base of each bottle whilst it is illuminated by the light source. As the bottles pass over the light source they are supported on a horizontal translucent plastics plate which is slowly rotatable about a substantially vertical axis. A rejection mechanism for rejecting dirty or faulty bottles from the bottle line in response to a signal from the photocell device is also disposed at the inspection position and is actuated immediately upon detection of a dirty or faulty bottle to remove the latter from the line, thereby making a pulse storage memory device unnecessary.
