ABSTRACT:
A facsimile apparatus for high-speed transmission of a plurality of images. If the last one line of an image data to be transmitted first among the connected images is not an all-white line, an all-white line is added to the data and the image data is MMR-encoded. Further, zero to N-1 "1" bits (N : a system bus width) are added to the coded data so as to render the coded data a multiple of a predetermined data unit. The coded data is transferred to a modem for image transmission. Thereafter, a subsequent MMR-coded image data is transmitted. The apparatus can thus transmit byte-packed image data stored in a memory in advance for image transmission without decoding and encoding the image data or re-executing byte-packing.
