A facsimile apparatus having an energy saving function includes an auxiliary controller or subcontroller for managing the conditions of the apparatus. While the subcontroller is in operation, a time manager manages the duration of a stand-by state of the apparatus and feeds time information to the subcontroller. A main controller delivers, before the stand-by state, a specified cancelling time for cancelling the stand-by state to the subcontroller. In the stand-by state, the subcontroller compares the time information and specified cancelling time. When the specified cancelling time is reached, the auxiliary controller cancels the stand-by state and causes power to be fed to the main controller and preselected units. |
