FIG. 6 shows a case where the first operation screen 100A is displayed in step S110 and the second operation screen 100B is displayed in step S140, but the present disclosure is not limited to this. The display control unit 51 may display the second operation screen 100B or the third operation screen 100C on the operation panel 30 in step S110. When the multifunction machine 1 is turned on, the operation screen 100 displayed on the operation panel 30 is stored in the memory 40 in advance. When the second operation screen 100B is displayed in step S110, the display control unit 51 can display the first operation screen 100A or the third operation screen 100C in step S140. When the third operation screen 100C is displayed in step S110, the display control unit 51 can display the second operation screen 100B in step S140.

When switching the operation screen 100, the display control unit 51 displays the operation screen 100 having different background images 115 on the operation panel 30. By visually recognizing the background image 115, the user can easily determine which operation screen 100 is displayed on the operation panel 30. This makes it possible to improve the operability by the user of the multifunction machine 1.
