Consider a case where the operation panel 11 is stored in the case 15 from the state in which the operation panel 11 is protruded after cooking is completed. The operation panel 11 enters the inside of the case 15 around the axis 16. In the process, the operation surface 12 and the display surface 13 (operation top surface) form a curved surface with the operation surface 12 side being convex. Therefore, the distance between the shaft 17 and the shaft 17 is almost the same at any point on the operation top surface, so that the gap between the operation top surface and the case flange 15 does not become extremely large. Since the inside does not become completely visible or a finger is not pinched, a highly safe device can be provided.

As described above, since the gap does not become large, it is possible to form an operation section that is good in appearance. In addition, when the operation panel 11 is protruded when the operation unit is used and the position of the end of the operation top surface is the same between a flat surface and a curved surface, the operation top surface area should be larger in the case of the curved surface. Therefore, it can be used effectively for arranging switch keys, and the size of characters can be increased, so that a device which is very easy to use and easy to operate can be provided.

In addition, since the gap between the operation panel and the case can be made small during rotation, even if the operation surface is flat even if the operation surface is unusually flooded, such as when water is splashed during the rotation process. Can significantly reduce the amount of water entering the interior, which is also very effective against flooding.
