Abstract
A stacker for handling and counting documents such as, for example, paper sheets, paper currency and the like in which the documents are fed from an input tray through cooperative feeder and stripper assemblies which separate the documents to feed them in a one at a time fashion in a forward feed direction toward acceleration rollers which accelerate the single-fed documents to create a gap between documents moving along the feed path. A gap detector senses the presence of gaps for document counting purposes. An endorser and/or suspect examination detector for examining the authenticity of paper currency may be provided downstream of the first acceleration rollers. The stacker comprises second acceleration rollers cooperating with a guide plate which reverses the direction of movement of the paper documents passing through the endorser station to further accelerate the documents and urge them along a convex guide path and into the pockets of a document receiving stacker wheel assembly which delivers the documents to a stacker tray positioned substantially beneath the infeed stacker to facilitate removal and handling of stacked documents.
