<P>PROBLEM TO BE SOLVED: To control return from a power saving mode to a normal operation mode and effectively reduce power consumption. <P>SOLUTION: An image-forming device Gk, when an optional functional operation and a returning time for returning from the power saving mode which reduces or stops power supply to main parts to the normal operation mode which is a power supply state where normal operation is possible are associated with each other and set as a return information by an input section 12, its control section 11 memorizes the return information in a memory section 15 and determines the highest priority functional operation return time as a returnable time by prioritizing the functional operations of several return information memorized by the memory section 15 based on the pre-set priority, and when the current time reaches the returnable time, returns from the power saving mode to the normal operation mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
