Abstract
The present facsimile machine comprises a system control unit, including a pair of central processing units (CPU's), and main and auxiliary power supplies. In one embodiment of the present invention, the second (slave) CPU receives power from the auxiliary power supply to constantly monitor the facsimile system. Upon receipt of a predetermined signal, the second CPU causes the main power supply turned on to render the first (master) CPU operative, thereby the second CPU becomes functionally dependent upon the first CPU. In another embodiment of the present invention, various functions of the facsimile machine are shared by the two CPU's. That is, one CPU is directed to control the communication-related functions with the other CPU directed to control the mechanism-related functions.
