  As described with reference to FIG. 1, the identification information reading unit 19 includes the determination circuit 19 a and the fitting unit 19 b and reads the identification information of the in-vehicle jig 2.

  The specific data storage means 20 bears the specific data storage means of the present invention, and stores specific data in association with the identification information of each vehicle, that is, each in-vehicle jig 2. FIG. 3 is a diagram showing the contents of the specific data stored in the specific data storage means 20 and the data structure thereof.

  With reference to FIG. 3, the content of the specific data stored in the specific data storage means and its data structure will be described. In this embodiment, the specific data includes vehicle type setting information such as large / medium / normal, registration information such as home position / registration route, and travel route history / POI search stored as a result of using a portable navigation device. History information such as history is defined.

  The vehicle type as the setting information is used, for example, when executing a toll road usage fee calculation process by the control means 10 or a route search process in consideration of a large automobile prohibited road. Registration information such as home position and registered route can be specified as a starting point or destination in route search processing by the control means 10 by selecting a registered specific point, or by selecting a registered specific route. This is used when the guidance means processing by the control means 10 by the user's favorite route is immediately started. History information such as travel route history and POI search history can be input by inputting better search conditions while referring to candidate routes searched in the past by the vehicle, or by displaying POI search history on the display screen. This is used when the control means 10 performs processing so that the user can smoothly perform route search and POI search.

  Then, as shown in FIG. 3, these specific data are stored in the respective storage areas in association with the in-vehicle jig identification information 2 a to 2 c for each setting information, registration information, and history information.

  With the configuration as described above, in the portable navigation device 1, the power is turned on when the portable navigation device 1 is attached to any vehicle-mounted jig 2 or is already attached to the vehicle-mounted jig 2. Then, the identification information reading means 19 reads the identification information of the in-vehicle jig 2 and stores it in the temporary storage memory of the control means 10. When executing the above-described specific processing, the control unit 10 selectively reads out the corresponding specific data from the specific data storage unit 20 based on the identification information. When specific data is newly obtained through user operation, route search processing, or the like, the control means 10 stores the specific data in the specific data storage means 20 in association with the identification information.

  Next, an example of an in-vehicle navigation system to which the present invention is applied will be described with reference to FIG. 4, as shown in FIG. 1, three in-vehicle jigs 2 a to 2 c are individually attached to three vehicles α, β, γ, respectively, so that one portable navigation device 1 is shared. 1 illustrates a constructed navigation system of the present invention.

  As shown in FIG. 4, all of the metal pins P1, P2, P3 project from the in-vehicle jig 2a attached to the vehicle α, and the identification information reading means 19 (discrimination circuit) of the portable navigation device 1 is provided. 19a), when all of the metal pins P1, P2, P3 of the in-vehicle jig 2 are detected, the portable navigation device 1 can determine that the vehicle α has the in-vehicle jig 2a attached thereto. . In addition, as shown in FIG. 3, since the setting information D1, the registration information D2, and the history information D3 are stored in association with each other in the vehicle α, the portable navigation device 1 is used in the vehicle α. The specific process based only on the specific data D1 to D3 associated with the vehicle α can be performed.

  Similarly, the on-vehicle jig 2b attached to the vehicle β is provided with metal pins P2 and P3, but is not provided with the metal pin P1. For this reason, when only the metal pins P2 and P3 of the in-vehicle jig 2 are detected by the identification information reading means 19 (discrimination circuit 19a) of the portable navigation apparatus 1, the in-vehicle jig 2b It can be determined that the vehicle β is attached. Since the setting information D4, registration information D5, and history information D6 are stored in association with the vehicle β, when the portable navigation device 1 is used in the vehicle β, the vehicle β is associated with the vehicle β. Specific processing based only on the specific data D4 to D6 thus obtained can be performed.

  Similarly, only the metal pin P3 protrudes from the in-vehicle jig 2c attached to the vehicle γ, and the metal pins P1 and P2 are not provided. For this reason, when only the metal pin P3 of the in-vehicle jig 2 is detected by the identification information reading means 19 (discrimination circuit 19a) of the portable navigation apparatus 1, the in-vehicle jig 2c is attached to the portable navigation apparatus 1. It is possible to determine that the vehicle is a vehicle γ. When no metal pin is detected, the mobile phone operates as a portable mode that can be taken out of the vehicle and used.

  As described above, according to the navigation device of the present embodiment, even if one portable navigation device 1 is shared by three vehicles α, β, and γ, the user can use any portable navigation device for any vehicle. There is no need to be aware of whether the device is attached, and practically the same usability as when the portable navigation device 1 is attached to each vehicle α, β, γ can be obtained.

  In the application example of the present invention shown in FIG. 4, the user A, the user B, and the user C who are owners of the vehicles α, β, and γ of the respective vehicle types use the portable navigation device 1 as one person's vehicle. It is suitable for sharing, and can be widely applied to other modes.

  5 and 6 are diagrams showing other examples of the in-vehicle navigation system to which the present invention is applied. For example, as shown in FIG. 5, the present invention can also be applied when a single user uses a plurality of vehicles. In the above-described embodiment, the specific data is individually set as setting information, registration information, and history information for each vehicle type and user, but the specific data may be configured to be shared and specified for each user. That is, when one user shares one portable navigation device for three vehicles α, β ′, and γ as shown in FIG. 5, registration information and history information are individually designated as specific data. By not doing, the registration information D2 and the history information D3 can be shared by each vehicle.

  Furthermore, it can comprise so that specific data may be stored based on the identification information of the vehicle-mounted jig | tool which considered user information and vehicle type information, and may be utilized for a specific process by comprising so that vehicle designation | designated may be received. For example, as shown in FIG. 6, when the users A and B who are the owners of the same vehicles β and β ′ share a single portable navigation device, the setting information D4 is set for each vehicle. Can be shared in Note that the setting information of the users B and D who are the owners of the vehicles β and δ of different types even in the same medium-sized vehicle type is set to be different from D4 and D10.

  In this way, the present invention can also be applied to a case in which a plurality of users arbitrarily use a plurality of vehicles using a single portable navigation device. In this case, since it is possible to obtain different information processing outputs for each user even for the same type of vehicle, each user's own portable navigation device is substantially attached to each vehicle.
