Abstract
A spring-driven pusher assembly of a merchandise dispenser in which the spring is carried entirely on the pusher assembly behind the articles being dispensed to thereby eliminate any interference problems with RF signals or the like used for purposes of determining inventories and the like. Preferably, the spring is a spiral spring that rotates a drive wheel when the spring uncoils. The drive wheel cooperatively engages a guide track on the base of the dispenser, and the rotation of the drive wheel causes the pusher assembly to advance along the guide track toward the dispensing end of the dispenser.
