Title: Map vending machine

Abstract: Folded documents are singly fed from the bottom of a stack by an ejector having a pin, hook or catch along one edge which moves below the bottom of the stack and is selectably slidable so as to engage the lowermost document. The lowermost document is slidingly delivered through an aperture by the ejector which, in one embodiment, grips the rear edge of the document while, in other embodiments, the bottom surface of the lowermost document is embedded with a pin or otherwise frictionally engaged. An adjustable slide restrictor plate can be positioned so as to prevent more than one document from exiting from a slot while permitting sufficient vertical motion of the plate so as to accommodate variable document thicknesses such as from folding irregularities associated with the document being ejected. An additional plate follows the top of the document stack and includes an engaging stub to prevent machine actuation when the stack has been depleted. A pendulously mounted follower weight can be included to assist in proper document feeding.
