Abstract
A facsimile communication machine capable of transmitting and receiving coded picture data is provided. The machine comprises a system control unit including a pair of CPUs, one of which is capable of controlling the reading operation while the machine is in transmission mode and the recording operation while the machine is in receiving mode and the other of which is capable of controlling the coding operation while the machine is in transmission mode and the decoding operation while the machine is in receiving mode. With the use of such a pair of CPUs, parallel processing of reading and coding operations and of decoding and recording operations can be carried out, thereby allowing to significantly increase operational speed.
