Abstract
Abstract A bulk coin hopper has an angled rotating disk positioned at the bottom of a chamber. A circumferential edge of the rotating disk communicates with an exit slot, from which coins are ejected. Overlapping such disk at the opening is a dispensing disk which is adapted for engaging coins carried by the first-named disk and ejecting the same from the slot.
