Abstract: A document distribution terminal can be required to process large volumes of data. To do this rapidly and efficiently, the terminal herein is organized to process all of the data in specialized peripheral devices. A supervising central processing unit controls the terminal but does not perform any data processing. The functions of entering data, scanning documents, encrypting data, compressing data, transceiving data, decompressing data, decrypting data and printing data are all performed in parallel by specialized devices working directly with a memory. A peripheral processing controller initialized by the central processing unit controls time-shared access to the memory by the specialized devices.

Abstract: A facsimile system is so controlled as to reduce four successively scanned source documents and print all four reduced copies on a single copy page. The system prints one of the source documents (44) in each quadrant of the copy document. The images are reduced in the horizontal dimension by discarding every other picture element in the scan image and in the vertical dimension by increasing the speed of the scanner (40) so that the size of the picture element in the vertical dimension is doubled. At the receiver, two scanned and reduced images will be printed on the left-hand half of the copy document (12). Subsequently, two additional scanned and reduced images are printed on the right-hand half of the copy document. When printing the right-hand half of the copy document, the printer is controlled to start printing at the horizontal mid-page of the copy document rather than the left-hand edge of the copy document.

Abstract: MULTIPLE IMAGE FACSIMILE The apparatus shown herein controls a facsimile system to reduce four source documents and print all four reduced copies on a single copy page. The facsimile system prints one of the source documents in each quadrant of the copy document. The images of the source documents are reduced in the horizontal dimension by discarding every other picture element in the scan image. The images are reduced in the vertical dimension by increasing the scanner speed so that the size of the picture element in the vertical dimension is doubled. At the receiver, two scanned and reduced images will be printed on the left-hand half of the copy document. Subsequently, two additional scanned and reduced images are printed on the right-hand half of the copy document When printing the right-hand half of the copy document, the printer must be referenced to start printing at the horizontal mid-page of the copy document rather than the left-hand edge of the copy document.
