Abstract

Disclosed is a device which provides transparency document handler capability for use with, for example, an overhead projector. The document handler device allows an operator to input a stack of transparencies ordered up for presentation. During the presentation, the transparency sheets are individually advanced to the viewing or projection location on a platen. The device is analogous to a photographic slide projector in that individual images are separately and sequentially projected based on predetermined ordering of images. Conventional paper handling technologies can be readily adapted for the purpose of advancing to, and removing from, individual transparency sheets from the projection location.
