And the identification information of the ETC in-vehicle device 20 are transmitted, and the toll gate data and the like passed from the roadside device are received.

  The identification information storage unit 23 stores vehicle-mounted device identification information unique to the ETC vehicle-mounted device 20. As described above, the vehicle-mounted device identification information is used for wireless communication with a toll road device.

  The setup information storage unit 24 stores setup information. The setup information is encrypted on the ORSE side, and includes vehicle number information associated with the ETC vehicle-mounted device 20 at the time of setup work, and vehicle classification information.

  When the ETC in-vehicle device 20 is connected to the navigation device 10, the ETC card is naturally inserted and removed by the user. For this reason, the user performs an operation of sliding and opening the front panel (referred to as panel opening operation). When the front panel is opened by the panel opening operation, the ETC card attached to the ETC vehicle-mounted device 20 can be removed, so that it is necessary to prevent theft. To do this, when a panel open operation is performed, a verification code such as a password or ETC card ID number is entered for verification, and after confirming that the user is a legitimate user, the front panel is opened. What is necessary is just to comprise so that it may open.

  However, this panel open operation is also performed when a DVD or SD card is inserted or removed when using other functions of the navigation device 10, such as a music or image playback function or a terrestrial digital broadcast viewing function. . When the collation method as described above is adopted, it is necessary to input a collation code every time the panel opening operation is performed, even though there is no intention to remove the ETC card.

  Therefore, in the navigation device 10 according to the embodiment of the present invention, when the panel open operation is performed, a confirmation inquiry for confirming whether or not the ETC card is removed and a verification code input screen are displayed, and the ETC card is removed. Only in such a case, the input of the verification code is requested and the front panel can be opened when the verification is successful. If the ETC card is not removed, the front panel will be opened unconditionally. In this case, the ETC on-board unit 20 is operated with a lock mechanism for locking the ETC card so that the ETC card cannot be removed. .

  FIG. 5 is a diagram showing an example of a confirmation inquiry and a verification code input screen for confirming whether or not the ETC card has been removed when a panel open operation is performed. The screen example in FIG. 5 is configured to display a confirmation screen for allowing the user to check whether or not the ETC card has been removed and a verification code input field on the same display screen. A screen for inquiring whether or not an ETC card extraction is selected and the screen may be changed to a verification code input screen.

  If the user removes the ETC card according to the display of FIG. 5, the user selects “YES” and inputs a verification code. The verification code may be a personal identification code set by the user or an ETC card ID code. The navigation device 10 performs collation based on the inputted collation code, and opens the front panel when collation is obtained. If verification is not possible, a warning screen or error screen is displayed, or a verification code is input again.

  If the ETC card is not removed, “NO” is selected. When “NO” is selected, the navigation apparatus 10 activates the ETC card locking mechanism in the ETC on-board unit 20 so that the ETC card cannot be removed, and then opens the front panel. By adopting such a configuration, it is possible to prevent the ETC card from being illegally removed without requiring a complicated operation from the user.

  In addition, it is set as the structure which detects whether the ETC onboard equipment 20 is mounted | worn with the navigation apparatus 10, and when the ETC onboard equipment 20 is not mounted | worn, when a panel open operation is performed, the confirmation inquiry mentioned above The front panel is preferably opened without displaying the verification code input screen.

  Further, when the ETC on-vehicle device 20 is mounted, the vehicle classification information stored in the setup information storage unit 24 of the ETC on-vehicle device 20 is compared with the vehicle classification registered in the navigation device 10, and the vehicle classification is determined. If they do not match, the fact can be notified to the user through the monitor screen of the navigation device 10 or a speaker. Thereby, it becomes possible to prompt the user to confirm the matching between the vehicle classification of the vehicle to be used and the vehicle classification registered in the ETC on-board unit 20. Therefore, when it is mounted on a vehicle different from the vehicle classification registered in the ETC on-vehicle device 20, it is possible to call attention such as inconvenience in calculating the highway toll.

  FIG. 6 is a flowchart showing an operation procedure of the navigation device 10 described above. The following description will be made on the assumption that the navigation device 10 is equipped with the ETC vehicle-mounted device 20. When the user wants to open the front panel, he / she operates the operation unit 2 (the button for opening the front panel in the operation button group 12) to request the front panel to be opened (step S101).

  When there is a request for opening the front panel, the control unit 1 detects the ETC card mounting state in the ETC on-vehicle device 20 (step S102), and determines whether or not the ETC card is mounted in step S103.

  Here, the detection of the ETC card mounting state in step S102 may be a configuration in which the ETC on-board device 20 is inquired about the mounting state of the ETC card, or a configuration in which an ETC card mounting signal is directly acquired from the ETC on-board device 20 may be used.

  When the ETC card is not attached to the ETC on-vehicle device 20 (NO in step S103), the ETC card will not be stolen, so the control unit 1 drives the slide member to open the front panel (step) S108). When the ETC card is mounted on the ETC on-vehicle device 20 (YES in step S103), a screen for confirming whether or not the ETC card is removed is displayed on the display unit 3 (liquid crystal display 11) to make an inquiry. (Step S104).

  If there is a selection (inquiry answer) indicating that the ETC card is not removed (NO in step S104), the control unit 1 instructs the ETC on-board unit 20 to operate the ETC card lock function so that the ETC card cannot be removed. (Step S106), the slide member is driven to open the front panel (Step S108).

  The operation of the lock function and the opening of the front panel may be performed simultaneously within a range in which the lock function can be operated before the front panel is opened to a position where the ETC card can be removed.

  When there is a selection (inquiry answer) indicating that the ETC card has been removed (YES in step S104), the control unit 1 displays a verification code input screen on the display unit 3 (liquid crystal display 11), and displays the verification code to the user. Is requested (step S105). When the verification code is input, the control unit 1 compares with a predetermined verification code in step S107 to determine whether or not the input verification code is correct.

  If it is determined that the correct verification code has been input as a result of the verification (YES in step S107), the control unit 1 drives the slide member to open the front panel (step S108). On the other hand, if it is determined that the correct collation code has not been input (NO in step S107), the display returns to the collation code input screen in step S105, and an input retry is requested.

  In this case, if the correct verification code is not input even after retrying the verification code a predetermined number of times, a warning may be displayed and the front panel open process (the process of this flowchart) may be terminated. Moreover, when the ETC onboard equipment 20 is not mounted | worn, it is preferable to comprise so that the process of this flowchart may be skipped.

  As described above in detail, according to the navigation device having the ETC on-vehicle device attaching / detaching mechanism according to the present invention, the ETC on-vehicle device 20 can be arbitrarily attached to the navigation device 10, and the ETC on-vehicle device 20 is attached. When an operation to open the front panel of the navigation device 10 is performed, the verification code input is requested only when the ETC card is removed, so that the ETC card can be prevented from being stolen. For this purpose, the operation when opening the front panel is not complicated.

  In the above embodiment, when the panel open operation is performed, it is confirmed whether or not the ETC card is to be removed, and if it is selected that the ETC card is not to be removed, the ETC card lock function is activated to activate the ETC card. Open the front panel. That is, if there is no panel opening operation, the lock function is not activated. However, the present invention is not limited to this. For example, when the ETC card reader 21 detects the ETC card installation, the ETC card lock function is activated. When the panel open operation is performed, confirm whether or not to remove the ETC card. If it is selected that the ETC card is not removed, the front panel can be moved with the lock function activated. Open. When the user selects to remove the ETC card, the user is prompted to input a verification code. When the correct verification code is input, the lock function is released and the front panel is opened. That is, the lock function of the ETC card is always operated so that the ETC card cannot be removed, and the lock function may be released only when a correct verification code is input when the ETC card is removed.

  In the above embodiment, the present invention has been described by taking a navigation device having an ETC on-vehicle device attaching / detaching mechanism as an example. However, the present invention is not limited to this, and the present invention is also applicable to a navigation device integrally including an ETC on-vehicle device. be able to.
