ABSTRACT:
A method and apparatus for counting the exact number of electrical circuit components carried by a length of component dispensing tape is disclosed. In the preferred embodiment, the invention uses optical detectors to detect the transmission of light through tape index holes and component carrier compartment holes and variously to increment or inhibit operation of a counter accordingly. In one form of the invention, the circuitry is adapted to detect automatically whether the tape is optically transmissive or opaque and to modify the counting scheme accordingly.
