Abstract

A dispensing unit includes a tray system including front, rear and side walls with partitions dividing the system into a plurality of trays and a support slidably supporting the tray system between a product dispensing position and a product restocking position. Each tray has a slot in its bottom between the front and rear walls with a pusher plate slidably supported in the slot and biased toward the front wall. The support has a stop which moves all of the pusher plates toward the rear wall when the tray system is moved to the restocking position and a latch mechanism holds the tray in the product dispensing position.
