Patent ID: 8437052

Claim:
An image forming apparatus comprising: an operation display unit mounted on an apparatus main body such that an angle of inclination thereof to horizontal direction is adjustable and adapted to display various operation images, a detecting unit for detecting the angle of inclination of the operation display unit, an operation executing unit for executing an associated processing relating to an image formation when the detecting unit detects that the state of the operation display unit has been adjusted from an initial state, and a rotating device for rotating the operation display unit by changing the angle of inclination of the operation display unit to the horizontal direction, wherein the operation executing unit registers values set by the user for various items in accordance with operation commands received by the operation display unit and resets the registered set values to defaults for the respective items when the operation display unit is rotated by the rotating device from a first state where an operation surface of the operation display unit lies horizontally to a second state where the operation surface is at a larger angle of inclination than in the first state, the second state is set in a case where the user operating the operation display unit is a wheelchair bound person, the detecting unit includes an inclination angle detecting sensor for detecting the angle of inclination of the operation display unit, and the orientation executing unit resets the set values to the defaults when a detecting signal outputted from the inclination angle detecting sensor indicates that the operation display unit is rotated to the second state.
