ABSTRACT:
A vending machine/display unit (10) includes a plurality of articles (14) arranged on a plurality of dispensing paths (20 or 22). A counting mechanism is associated with each dispensing path, and includes an encoder bar (32) positioned adjacent the dispensing path, and encoder head (34) positioned to incrementally advance along the dispensing path. The encoder head (34) includes a plurality of contact members (42a-d) which interact with a plurality of active site contact members (40) disposed on the encoder bar (32) in a pattern which uniquely identifies each incremental position in the dispensing path. The inventory of articles (14) remaining in a dispensing path or the accounting of articles (14) dispensed from the dispensing path is determined from the relative position of the encoder head (34) to the encoder bar (32), and this position is detected from the active contact site points (40) on the electrical information lines (36) on the encoder bar (32).
