Abstract
A mode setting device for an electrophotographic copier or similar office machine of the type having a machine body, a housing, an openable cover forming a part of the housing, and a power supply which is turned on and off in interlocked relation to the opening and closing of the cover member. The device includes a mode preservation commanding switch and a non-volatile memory which stores operation modes of the machine having been selected before the turn-off of the power supply. When the power supply is turned off after the commanding switch has been turned on and then turned on again, the operation modes of the machine stored in the non-volatile memory are automatically set up again. When the commanding switch is turned off, the operation modes of the machine are initialized as soon as the power source is turned on again. The need for manipulations otherwise required for re-setting operation modes due to opening and closing of the cover member is eliminated.
