  Further, when the dial 46 is turned counterclockwise in advance when the screen is displayed in FIG. 5, the menu icons 36f to 36j are scrolled upward. Then, the menu icon 36j is located at the lowermost side of the color liquid crystal display unit 36 and is in a selected state. On the other hand, the menu icon 36f moves up one step from the state of FIG. Further, the menu icons 36g to 36i are moved up one level from the state of FIG. 5 and the non-selected state is maintained. That is, by turning the dial 46 counterclockwise, the menu icons 36f to 36j are scrolled upward, and the uppermost one of the menu icons 36f to 36j is returned to the lowermost side, so that the menu icon 36f The selected state and non-selected state of .about.36j can be changed.

  As is clear from a comparison between FIG. 5 and FIG. 7, the character included in the menu icon 36 f is “I am worried about calories” in the selected state, but becomes “Calories” when in the non-selected state. Further, the character included in the menu icon 36g is “I am worried about salt” in the selected state, but becomes “salt” in the non-selected state. As described above, the color liquid crystal display unit 36 displays the menu icons 36f to 36j so that the number of characters is smaller in the non-selected state than in the selected state. It should be noted that when the character included in the menu icon 36h is in a selected state, "I am worried about vegetable shortage", when the character included in the menu icon 36i is in a selected state, the character included in the menu icon 36j is selected. Then, “If you feel tired”.

  Further, when the menu icons 36f to 36j change from the non-selected state to the selected state, the size and the color change from those in the non-selected state. Specifically, when the menu icons 36f to 36j change from the non-selected state to the selected state, the menu icons 36f to 36j become larger than those in the non-selected state. The menu icons 36f to 36j are green when they are not selected, but are orange when they are selected. Further, when the menu icons 36f to 36j move from the uppermost position of the color liquid crystal display unit 36 to the lowermost position, and from the second position from the bottom to the lowermost position of the color liquid crystal display unit 36. When moving to the side position, that is, when the menu icons 36f to 36j are changed from the non-selected state to the selected state, the color of the menu icons 36f to 36j is changed from green to orange through a mountain blowing color. For example, the menu icon 36g is green in the screen display of FIG. 5, is bright in the screen display of FIG. 6, and is orange in the screen display of FIG.
