ABSTRACT:
Apparatus for inspecting capsules comprises a carrier belt which is formed into an endless belt configuration and can carry the capsules, with the capsules received separately in through-holes in the belt, and a plurality of parallelly disposed rotatable rollers which have axes of rotation extending substantially in parallel with the flow direction of the capsules being carried by the carrier belt. The rollers rotate the capsules which are in contact therewith. An optical inspecting device is provided for optically inspecting the surfaces of the capsules which are rotated in contact with the rotary rollers. The apparatus can accurately inspect very small defects on the surfaces of the capsules irrespective of the type of capsules, and is simple as well as compact in construction.
