Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for inspecting the external surface of a can capable of adapting to high-speed can manufacturing and can filling by accurately capturing image data on one circumference of the can through the use of information on one circumference of the can in a chuck for grasping the can even in the case that the external surface of the can presents difficulty in identifying one going-round of the can.  <P>SOLUTION: The external surface 2 of a rotating can 1 gripped by a chuck 10 is imaged over an angle range acquired by adding a marginal angle α to a full circle. The image data for one circuit of the can 1 is created on the basis of a scale 11 attached to the chuck 10 with reference to a mark location 5 detected from a bar code 4. Even in the case that the external surface 2 of the can 1 does not have any characteristics for specifying one circuit in the case of solid printing etc., it is possible to create the image data for one circuit of the can 1 by using the scale 11 and shorten the inspecting time. By comparing the image data on one circuit with image data on one standard circuit of a normal can, the external surface 2 of the can 1 is inspected.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
