Abstract: Medicinal capsules which are secured by machine to a backing strip are photoelectrically inspected by multiple pairs of light sources and detectors specially arranged so as to permit the simultaneous inspection of a number of closely spaced capsules arranged in a row. The extent to which a capsule is filled is determined by the time interval during which a light beam is blocked by the capsule contents. This interval is electrically compared with a standard time interval. After the backing strip is cut into separate cards, each carrying several capsules, the electrical comparison means effects rejection of any card containing an unsatisfactory capsule. Further means are provided for similarly rejecting cards having badly misaligned capsules. Should the apparatus sense an excessive number of unsatisfactory cards, the packaging machinery is automatically shut down.
