Abstract
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.

Claim 1
Independent Claim
208 words
A device for setting operation modes of a machine having a machine body, a housing surrounding said machine body, and an openable cover member forming part of said housing, and driven by a power supply unit, said device comprising: power supply shut-off means for shutting off at least a part of power supplies of said power source unit when said cover member is opened; store means for preserving data stored in said store means even when said power supply of said machine is shut off by said power supply shut-off means; commanding means for commanding preservation of operation modes of said machine; and control means for controlling said power supply unit, said store means and said commanding means; said control means causing said store means to store operation modes of said machine when said machine is being powered by said power supply unit; said control means initializing, when a command from said commanding means is absent, the operation modes of said machine after said machine has been powered by said power supply unit; said control means restoring, when the command from said commanding means is present, said machine to the operation modes stored in said store means after said machine has been powered by said power supply unit.
Claim 2
Independent Claim
208 words
A device for setting operation modes of a machine having a machine body, a housing surrounding said machine body, and an openable cover member forming part of said housing, and driven by a power supply unit, said device comprising: power supply shut-off means for shutting off at least a part of power supplies of said power source unit when said cover member is opened; store means for preserving data stored in said store means even when said power supply of said machine is shut off by said power supply shut-off means; commanding means for commanding preservation of operation modes of said machine; and control means for controlling said power supply unit, said store means and said commanding means; said control means causing said store means to store operation modes of said machine when said machine is being powered by said power supply unit; said control means initializing, when a command from said commanding means is absent, the operation modes of said machine after said machine has been powered by said power supply unit; said control means restoring, when the command from said commanding means is present, said machine to the operation modes stored in said store means after said machine has been powered by said power supply unit.
