As shown in FIG. 4A, first, the tip of the finger presses a point 41 a within the display range of the menu button 21. When the touch panel 19 is further pressed with a finger, as shown in FIG. 4B, the fingertip bends in the direction of the arrow 42 (vertical rolling phenomenon). If it does so, a press position will remove | deviate from the display range of the menu button 21, and it will move to the point 41b in the display range of the map 20. FIG. If the finger is removed from the touch panel 19 as it is, the pressing is stopped in the display area of the map 20. As a result, as shown in FIG. 6A, the process defined in the menu button 21 is not executed even when the menu button 21 is pressed. Then, the map 20 is scrolled as shown in FIG.

  The horizontal rolling phenomenon will be described with reference to FIG. As shown in FIG. 5A, first, the right belly of the finger presses a point 51 a within the display range of the menu button 21. When the touch panel 19 is further pressed with a finger, as shown in FIG. 5B, the fingertip rotates in the direction of the arrow 52 (lateral rolling phenomenon). If it does so, a press position will remove | deviate from the display range of the menu button 21, and it will move to the point 51b in the display range of the map 20. FIG. If the finger is removed from the touch panel 19 as it is, the pressing is stopped in the display area of the map 20. As a result, as in the case of the vertical rolling phenomenon described above, the process defined for the menu button 21 is not executed even when the menu button 21 is pressed. Then, the map 20 is scrolled.

  Therefore, in the embodiment of the present invention, as shown in FIG. 7, an insensitive area 71 a is provided on the outer periphery of the sensitive area 21 a that is the display area of the menu button 21. The sensitive area 21a is an area where the process defined in the menu button 21 is executed when the finger is released from the touch panel 19 and the pressing is stopped in this area. The insensitive area 71a is an area where no processing is performed even if the finger is released from the touch panel 19 and the pressing is stopped in this area. Accordingly, the map 20 is not scrolled even if the finger is released from the touch panel 19 to stop pressing in the insensitive area 71a. That is, as shown in FIG. 8A, even if the finger rolling phenomenon occurs after the menu button 21 is pressed and the finger is released from the touch panel 19 in the display area of the map 20, as shown in FIG. The map 20 is not scrolled. Similarly, a non-sensitive area 71 b is provided on the outer periphery of the sensitive areas 22 a and 23 a that are the display area of the wide area button 22 and the display area of the detail button 23.

  The insensitive area setting process of the navigation device 1 according to the embodiment of the present invention will be described with reference to the flowchart of FIG. The processing in FIG. 9 is executed in the control circuit 11 by a program that starts when a button is displayed on the display monitor 16.

  In step S901, data of a display range on the display screen of buttons displayed on the display monitor 16 is acquired. In step S <b> 902, it is determined whether the display range of the button overlaps with the sensitive area set on the touch panel 19. In the case of superimposing, affirmative determination is made in step S902, and the process proceeds to step S903. If not superimposed, a negative determination is made in step S902, and the process proceeds to step S906.

  In step S903, a sensitive area is set in the area of the button display range of the touch panel 19. When the touch panel 19 has been pressed in this sensitive area, the process defined for the button is executed. In step S904, the insensitive area is set on the outer periphery of the area of the button display range. Even if pressing of the touch panel 19 is finished in this insensitive area, the sensitive area processing that is set to be superimposed on the button display range is not executed. In step S905, it is determined whether a button is displayed. If it is displayed, step S905 is repeated. If no button is displayed, a negative determination is made in step S905, and the insensitive area setting process for the button is terminated.

  In step S906, a sensitive area is set in the area of the button display range. Then, the process proceeds to step S905.

  In step S903, a sensitive area is set in the area of the button display range, and the process advances to step S1201. In step S1201, it is determined whether the button display range is pressed. If the button is pressed, an affirmative determination is made in step S1201 and the process proceeds to step S1202. If not pressed, a negative determination is made in step S1201 and the process proceeds to step S1204.

  In step S1202, the sensitive area is expanded. In step S1203, it is determined whether the button display range is pressed. If it is pressed, step S1203 is repeated. If not pressed, a negative determination is made in step S1203, and the process returns to step S902.

  In step S1204, it is determined whether the button is displayed. If it is displayed, an affirmative determination is made in step S1204, and the process returns to step S902. If not displayed, a negative determination is made in step S1204, and the process ends.

(2) In the embodiment of the present invention, the buttons 21 to 23 displayed on the display monitor 16 have been described. However, menus 81 to 84 displayed in a list as shown in FIG. 13 may be used.
