Abstract
Disclosed is a tire surface inspecting technique capable of surely discriminating rubber pieces of a quality different from that of a tire embedded in the surface of the tire by vulcanization from the tire. A first illuminating unitinclude paired first light projectorsandthat project light respectively from opposite sides toward an objective line L on a tire T. A second illuminating unitinclude paired second light projectorsandthat project light respectively from opposite sides toward the objective line L in a direction different from that in which the first illuminating unitproject light. The first illuminating unitand the second illuminating unitoperate alternately for illumination. The line cameraforms an image of a part of the surface of the tire corresponding to the objective line L in synchronism with the respective illuminating operations of the first and second illuminating unit. Illumination and image formation are repeated for different parts of the surface of the tire that are moved successively to a position corresponding to the objective line L. Images formed by the line camera are analyzed for the inspection of the surface of the tire T.
