Apparatus and means are provided for the quality control of hard shell pharmaceutical capsules comprising a set of collets or holders arranged side-by-side in a row for supporting and moving successive sets of individual capsule shells open-end foremost in timed relation from a work station, photosensor means for scanning a light beam projected across the path of the conveyed capsule parts, control means for activating the scanning mode during a predetermined time segment in the motion cycle such that during the time segment the light beam bypasses the leading edge of advancing standard-length capsule parts but is blocked and prevented from being scanned by the intervention of any over-length capsule parts, and means responsive to the scanning means for signalling and/or rejecting capsule parts thus found blocking the beam.
