Abstract
A device for executing an inspection method of a filter rod for cigarettes includes an inspection drum ( ), and the inspection drum ( ) has plural pickup grooves ( ) for receiving one filter rod (F) each in its outer periphery. The filter rod (F) in each pickup groove ( ) is provided with rolling force by a rolling guide ( ), and passes through an illuminated region (B) of light while the inspection drum ( ) rotates. At this time, when the filter rod (F) rolls, the shielded portion of the illuminated region (B) due to the filter rod (F) varies. This variation means that the filter rod (F) is normal, and is hence used for determination of the inspection.
