Claims (1)

[Scope of utility model registration request] Image forming devices such as copying machines, printing machines, and printers have an auto clear mode that automatically changes to a certain mode when the machine is left unused for a predetermined period of time, and also has an auto clear mode that automatically changes to a certain mode by leaving the machine unattended for a predetermined period of time. In a device having an all-clear mode that performs the above-mentioned operation, there is a standard mode display means for indicating that auto-clear or all-clear has operated, an all-clear input means, and a mode state of the device before all-clear or all-clear operates. It has a memory for storing and a setting means for resetting the mode in the device using the contents of the stored memory, and also serves as an all clear input means and a mode setting means before clearing, and the operation of this means is A mode control device for an image forming apparatus, characterized in that when the standard mode display means is on, it acts as a pre-clear mode calling means, and when the display means is off, it works as an all-clear input means.
