FIG. 15). Note that the orange frame of the selection menu (reduced image representing the first option) and the dark brown frame of another menu (reduced image representing the second option) may be displayed.

  On the other hand, if it is determined that the selection menu moved in step S96 does not overlap with other menus, the process proceeds to step S99, and if it is determined that the finger is released from the touch panel 62, the process proceeds to step S100, and the process of restoring is performed. Then, the process returns to step S92. In this returning process, the image representing the moving selection menu returns to the original display position before the movement.

  On the other hand, if it is determined in step S99 that the finger is not released from the touch panel 62, the process returns to step S95.

-Example of cooking operation from the first screen-
In the first screen of the third display mode shown in FIG. 9, when the enlarged image G31 (“warm”) is selected by touching with a finger and then the “warm start” key 74 (shown in FIG. 3) is pressed, A screen for selecting “warming” is displayed on the color liquid crystal display unit 6.

  On this “warming” selection screen, a plurality of menus (such as “heating range” by microwave heating, “warming up tempura” by heated steam, etc.) can be further selected.

  Here, when the cooking menu using heated steam is selected, an image in which a tray with a net placed in the heating chamber is mounted in the middle is displayed on the color liquid crystal display unit 6, and the letters “middle” and an arrow are displayed. The position of the tray is shown in red. Furthermore, the characters “water tank” and a picture of water droplets are displayed in light blue on the color liquid crystal display unit 6, and this indicates that the water in the water tank 11 is used in cooking using the hot water vapor. The user is alerted about the presence or absence of water.

  Then, when the “hot start” key 74 is pressed while the color liquid crystal display unit 6 displays a screen for starting cooking using heated steam, heating cooking using superheated steam is performed by the heating cooking control unit 200g. Begins.

  In this way, at the start of the selected cooking menu, the characters “water tank” and the picture of water drops are displayed in light blue, so that the selected menu can be cooked using water without looking at books such as a cooking collection. This is easily recognized by the user, and it is also possible to prevent starting cooking without water.

  According to the display device used in the cooking device having the above-described configuration, ten images (icons) representing ten options are displayed by the first option display control unit 200a of the control device 200 in the first and second display modes. By simultaneously displaying on one screen of the color liquid crystal display unit 6, it is possible to select an image (icon) representing a desired option from 12 images (icons) representing 12 options by operating the touch panel 62. . In the third and fourth display modes, the second option display control unit 200b of the control device 200 divides the plurality of options into a plurality of groups, and a plurality of screens corresponding to each group of the color liquid crystal display unit 6 In addition, twelve enlarged images (icons) representing twelve options whose display sizes are enlarged are displayed compared to when the first option display control unit 200a displays the color liquid crystal display unit 6 on one screen at the same time. As a result, an enlarged image (icon) representing a desired option is selected from 12 enlarged images (icons) representing 12 choices displayed on the first to third screens of the color liquid crystal display unit 6 by operating the touch panel 62. It becomes possible to do. Here, the second option display control unit 200b switches the first to third screens corresponding to each group of the color liquid crystal display unit 6 on the basis of the operation signal from the touch panel 62, and expands the options of each group. Since images (icons) are sequentially displayed, enlarged images (icons) representing desired options can be easily selected from the first to third screens of the color liquid crystal display unit 6. Therefore, it is possible to realize a display device in which the display size of a plurality of icons displayed on the screen can be changed and excellent operability and visibility can be obtained.

  In the above embodiment, a desired option is selected from the 12 options displayed on the first to third screens in the third and fourth display modes. However, the second option display control unit 200b allows a plurality of options to be selected. The options may be divided into two or four or more groups, and a plurality of options may be displayed on two or four or more screens corresponding to each group of the color liquid crystal display unit 6. The number of options displayed on one screen Is not limited to 4.

  Further, the display switching control unit 200c of the control device 200 displays ten images (icons) representing ten options by the first option display control unit 200a based on the operation signal from the touch panel 62.
