A road map 20 is displayed on the display screen, and a destination can be set at the pressed position by pressing the road map 20. Here, when the occupant tries to press the position 41 to set the destination, the VICS information is received, and the VICS information reception screen 21 is interrupted and displayed on the display monitor 16 as shown in FIG. And

  In the navigation apparatus 1 according to the embodiment of the present invention, after the YES button 22 and the NO button 23 are displayed, the display range of the YES button 22 and the NO button 23 is sensitive until a predetermined time (for example, 0.5 seconds) elapses. Disable area. For this reason, no processing is performed even if the YES button 22 and the NO button 23 are pressed until a predetermined time has elapsed after the YES button 22 and the NO button 23 are displayed. Therefore, even when the YES button 22 is pressed by mistake, the graphic information 31 shown in FIG. 3 is not interrupted.

  If the NO button 23 is pressed after a predetermined time has elapsed since the YES button 22 and the NO button 23 are displayed, the VICS information reception screen 21 is deleted and the destination setting operation can be started again.

  Next, the above-described invalidation processing of the YES button 22 will be described with reference to the flowchart of FIG. In the present embodiment, the process of FIG. 5 is executed in the control circuit 11 by a program that starts when VICS information is received.

  In step S501, a button is displayed on the display monitor 16, and the sensitive area in the range where the button is displayed is invalidated. For example, even if the YES button 22 shown in FIG. 2 is pressed, the processing of the YES button 22 is not executed and the destination is not set. In step S502, the timer 11a is started. In step S503, it is determined whether a predetermined time has elapsed since the timer 11a was started. If the predetermined time has elapsed, an affirmative determination is made in step S503, and the process proceeds to step S504. If the predetermined time has not elapsed, step S503 is repeated. In step S504, the sensitive area of the YES button 22 is validated. Then, the sensitive area setting process ends.

  Next, an input process when the button displayed on the display monitor 16 is pressed will be described with reference to the flowchart of FIG. The processing in FIG. 6 is executed in the control circuit 11 by a program that starts when a button is pop-up displayed on the display monitor 16.

  In step S <b> 601, the pressed position of the touch panel 19 is detected from a signal output from the touch panel 19. In step S602, it is determined whether the pressed position is within the sensitive area of the button displayed on the display monitor 16. If it is within the sensitive area, an affirmative determination is made in step S602, and the process proceeds to step S603. If it is not in the sensitive area, a negative determination is made in step S602, and the process returns to the start. In step S603, it is determined whether the sensitive area is valid. If it is valid, an affirmative determination is made in step S603, and the process proceeds to step S604. If it is invalid, a negative determination is made in step S603, and the process returns to the start. In step S604, processing corresponding to the button is executed. Then, return to the start.

The navigation device 1 according to the above embodiment has the following effects.
(1) The sensitive area in the range in which the button is displayed is disabled until a predetermined time has elapsed since the button displayed in the pop-up is displayed. Therefore, when the user presses the touch panel 19 in order to execute a desired process, a button suddenly pops up, and even if the button is pressed by mistake, the process related to the button is not executed. Accordingly, erroneous operation of the occupant's touch panel 19 can be prevented.

The navigation device 1 of the above embodiment can be modified as follows.
(1) In the above embodiment, the case where the destination can be input using the entire screen as the sensitive area and the VICS information reception screen pops up in the destination input operation screen has been described. However, the display range of the sensitive area of the pop-up button may be invalidated for a predetermined time only when the sensitive area already displayed overlaps the sensitive area of the pop-up button. This is because the above-described erroneous operations do not occur unless the sensitive areas overlap. Therefore, when the above-described erroneous operation does not occur, the pressing operation can be performed even immediately after the button is displayed, and the pressing operation on the touch panel 19 can be performed quickly.

(2) The sensitive area of the display range of the YES button 22 is invalidated when the VICS information reception screen 31 pops up. However, the button is not limited to the embodiment as long as the button is displayed when information is received from the outside. . For example, in a navigation device having an e-mail receiving function, when an inquiry notification screen as to whether or not to download the e-mail is popped up when receiving the e-mail, the display range of the YES button for answering the inquiry is displayed. It may be invalidated. In this case, useless downloading of e-mail can be prevented, and generation of useless communication charges can be prevented.

(3) Since the display screen of the display monitor 16 cannot be stared while the vehicle is traveling, there is a high possibility of erroneous operation. Therefore, only when the vehicle is running, the processing corresponding to the button may not be executed even if the button is pressed for a predetermined time after the button is displayed. In this case, the vehicle speed sensor 14b detects whether or not the vehicle is running.

  In the above embodiment, although the navigation apparatus was demonstrated, the information terminal device of this invention is not limited to vehicle-mounted use.

  According to the present invention, when a sensitive area is displayed, the sensitive area is invalidated until a predetermined time elapses from the display time point, and when the predetermined time elapses, invalidation / validation processing means for validating the sensitive area; If it has a structure provided with, it will not be limited at all to embodiment described above.
