Abstract

In a facsimile system, as shown in Fig. 1, wherein a physical page of patterns to be transmitted is optically scanned and then temporarily stored in a work buffer of compressor/decompressor (COM/DEC) in the form of digital raw image which is further compressed and then stored in an image buffer of the controller's RAM (random-access memory) for transmission in the form of digital codes forming a logical page of the patterns which is terminated by an End of Page (E0P) code, the scanning and compressing of the physical page is controlled by the controller's program specifying the number of lines to be scanned, through a special interface between the controller and the COM/DEC to prepare various kinds of logical pages.
