SOLUTION: When a mode selection key on an operation part is pressed, it is judged whether a selected mode is changed or not. When there is no change, a direct motion to an exist is performed; when there is a change, an instruction of motion interruption is given to a mode before change, that is, a mode that is currently operating, and an interruption of the operating mode for the interruption instruction is waited. When an interruption processing is completed, a set is changed to the selected mode, a motion is made to stop and the processing is completed. That is, a display is performed on a display part 301 as shown in the Fig. and a set of the order of priority is performed by the mode such as a copy, a fax, a file or a printer.
