ABSTRACT:
An apparatus for feeding documents from a stack of documents, in single file, into a document track, with the apparatus employing an endless belt. The endless belt is mounted on a drive roller and an idler roller to provide a linear portion of the belt which is parallel to the first document to be fed from the stack. The apparatus also includes a retard mechanism which includes a first portion to engage the documents in the stack and also includes a second portion which is parallel to the linear portion of the endless belt and is biased towards the linear portion by a tension spring. The endless belt is made of a material which is designed to wear instead of "glazing" which provides for a positive feed. The endless belt and the retard member are designed to be replaced by an operator of the terminal in which the apparatus is located so as to avoid a service call by a maintenance person.
