DOCUMENT AND INFORMATION STORAGE AND RETRIEVAL SYSTEM

Documents or information in the form of microfilm, microfiche or other permanent form are mounted on rectangular frames or carriers which are edge coded. A plurality of carriers are stored in a random manner in spaced slots arranged in one or more elongated storage bins with the bins arranged side by side. A bridge which carries a random document locator and retrieve and refile head assembly is adapted to move across the bins to a selected bin. The document locator, retrieve, and refile head assembly then moves along the bridge over the selected bin to store or retrieve selected carriers. During location, the coded edges are scanned to locate the desired carrier; an electrical control starts the retrieve cycle to pick up the carrier having the desired document and deposits the carrier on a conveyor system for transport to an output location where the document or information is presented to a video camera and the signal from the camera may be transmitted to a remote video terminal for viewing. The carrier is then returned to the document refile assembly along the same conveyor system where it is picked up and refiled by the head assembly.
