Abstract

A multiple-access facsimile signal receiver is connected to a plurality of telephone lines (1, 2 and 3). The receiver includes a single document printer circuit (5), a memory (15) for storing digital facsimile signals as demodulated from the telephone lines by demodulator circuits (12). The facsimile signals are applied to the data input of the memory via a multiplexer (16). The signals are read from the memory by a decoder (20) which applies them in decoded form to the printer via a pair of output buffer registers (21 and 22). A memory read/write control circuit (17) co-ordinates the writing of input data into the memory and the reading of data from the memory. The pooling of memory space between a plurality of lines makes it possible to use less memory than would be required if each line had its own exclusive memory. <IMAGE>
