ABSTRACT:
A document data input system for a scanner capable of storing scanner data to another buffer memory of a microprocessor when applying the scanned data to a host computer. The document data input system comprises a host computer for storing scanned data to its internal hard disk, a scanner for scanning the document data, a scanner interface unit for interfacing between the host computer and the scanner, a microprocessor associated with a global memory and a local memory, and an interface unit for latching the data from the scanner interface unit and applying the data to the microprocessor, and applying a completion signal to the scanner interface unit when the data input to the microprocessor is completed.
