Abstract
A low power dissipation facsimile apparatus is capable of accommodating a plurality of lines. This apparatus is arranged to reduce the power consumption still more. The apparatus comprises a first control unit having a low power dissipation mode, which controls a first line and the entire body of the facsimile apparatus, and a second control unit having a low dissipation mode, wherein controls a second line and transfers communication data to the first control unit. Then, for the reception only on the first line, and also, for the transmission and the copying operation, the first control unit rises from the low power dissipation mode to execute operation accordingly. Also, for the reception only on the second line, only the second control unit rises from the low power dissipation mode to operate the reception, and at the same time, during reception or after the completion of reception, the first control unit rises from the low power dissipation mode to transfer the received data from the second control unit to the first control unit for printing out images.
