Abstract

An image acquisition subsystem, electronic processing subsystem and workstation subsystem produce information management networks that are almost unlimited in size and scope in integrating data and information stored in both digital form and in human readable form. Integration is by on-demand conversion in a scanner/digitizer of data and information to a transmittable, compatible electric signal which is encoded and converted into human readable form at the workstation of an information requester. The scanner rejects improperly oriented microfiche and recognizes microfilm data in a right reading or reversing orientation. An electronic circuit presents the data to the system's buffer in the right reading orientation regardless of a right or reverse reading input from microfiche. The scanner/digitizer regulates scanning speed in conformity with the data rate and capability of the transmission line to absorb the data. A microprocessor master module performs various functions with only minor hardware changes.
