2. Description of the Related Art Conventionally, a car navigation device has a locator function of displaying the position of the vehicle on a scrolling map, a navigation function of guiding a road to a destination, and the like in recent years. Has achieved remarkable development as a product for private cars (for general users) by incorporating various functions.

As such a variety of functions, for example, a marking function for registering various destination points displayed on a map to make a map only for one's own purpose or a designated destination point There is a search function or the like for automatically searching the route to, which is useful for improving convenience such as the locator function and the navigation function described above.

In addition, public information such as traffic information, parking information, weather forecast, etc., and publicity information such as advertisements are "ATIS" using a telephone line, and "VIC" using a beacon.
A car navigation device that can directly use the information obtained from a communication system such as S ", FM multiplex broadcasting, etc. has already been developed, and the practical application of these services will be made soon. is there.

[0005]

However, the development of such a car navigation system corresponds to the leisure of general consumers such as driving. For example, an employee or a part-time worker who is unfamiliar with the delivery / collection area. On the other hand, there is a problem in using the car navigation device for the purpose of business such as guiding a large number of delivery / collection destinations. Because it is usual for business vehicles for delivery / collection business to go to many delivery / collection destinations at one delivery, in order to mark the delivery / collection destinations on the map, many This is because it is necessary to register (or delete) the delivery / collection destination of the item in the car navigation device, which is a considerably troublesome operation for the user.

In order to reliably carry out the delivery / collection business, the address, name, telephone number, delivery / collection, color, mark type, etc. of the delivery / collection destination, which is the subject of road guidance, are displayed on the display. If it can be displayed, it will be very useful for performing work, but it cannot be done by the conventional car navigation device.

Further, when it is desired to immediately send a business vehicle that is out to a place that was not scheduled, a pager, telephone or the like is usually used to inform the employee about the place to go. However, there is a limit to transmitting such information accurately and reliably by pager or telephone, so
In particular, when dispatching an employee to an unfamiliar place, information about the place to go may not be accurately and reliably transmitted.

Therefore, it is very effective if the system such as the above-mentioned "ATIS" can be used to directly input such information to the car navigation device and guide the road to the place where the user has to go. However, a system such as "ATIS" provides public information and the like to an unspecified large number of users, and allows a car navigation device mounted on a specific business vehicle to input specific information. I couldn't do that.

However, if the FLEX-TD system with an external terminal is introduced as a pager transmission system, the pager transmission speed can be increased, and the pager can be used as a data communication means (modem). Therefore, if a FLEX-TD type pager can be connected to the car navigation device, it becomes possible to add a communication function to the car navigation device, which is different from the car navigation device installed in a specific business vehicle. It becomes possible to input specific information.

Therefore, the present invention has been made to solve the above-mentioned problems, it is possible to handle a large number of destination points at a time, and information on the destination point or the like can be obtained via a pager. An object of the present invention is to provide a car navigation device that can handle business such as guiding a large number of delivery / collection destinations by enabling input.

[0011]

In order to achieve this object, a car navigation device of the present invention is a car navigation device for displaying a registered destination point on a map on a screen, the object stored in a storage medium.

Further, a car navigation device for displaying a registered destination on a map on a screen, comprising a connecting means for connecting with a pager, and displaying information about the destination received through the pager connected to the connecting means. Based on this, one or a plurality of destination points are collectively registered.

Further, it is characterized in that the destination points registered via the pager connected to the connecting means are erased collectively. Further, it is characterized in that the information on the specific destination is displayed on the screen based on the information on the destination received through the pager connected to the connection means.

In the car navigation system of the present invention having such a structure, if the destination points are registered, the destinations can be displayed on the map on the screen. However, when it is desired to register a plurality of destination points at a time. The information about a plurality of destination points is stored in a storage medium, and the plurality of destination points can be collectively registered by reading the information about the destination points with a reading unit.
Therefore, a plurality of destination points can be registered by a simple operation without registering the plurality of destination points one by one, and the plurality of destination points can be displayed on the map on the screen in an extremely short time.

Further, regarding the destination points registered collectively, the information about the destination points is stored in the storage medium, so that if one of the plurality of destination points is specified, the specified destination points are related. The information can be read from the storage medium by the reading means and displayed on the screen.
Further, since the collectively registered destinations are read by the reading means from the storage medium, it is possible to easily identify the registered destinations one by one, and only the collectively registered destinations can be identified. It can be erased in a batch. In addition, the information about the destination is letters, numbers,
Data such as marks is included. Moreover, according to the conventional technology,
It is also possible to register and delete individually and as a group.

Therefore, when the car navigation system of the present invention is used for the purpose of business such as to guide a large number of delivery / collection destinations to employees and part-time workers who are unfamiliar with the delivery / collection area. Very suitable. Because
In such a case, in order to display the delivery / collection destinations on the map, it is necessary to register (or delete) many delivery / collection destinations each time (before) delivery / collection to the car navigation device. By collectively registering a number of delivery / collection destinations as destinations, a large number of delivery / collection destinations can be displayed on the map on the screen in an extremely short time. Furthermore, with the conventional technology, if you specify one destination point among the registered destination points collectively, you can search and display the optimal route from the local point to the specified destination point,
Good when you want to guide one from the collection destination.

In addition, if the information about the destination point stored in the storage medium includes information such as the destination address of delivery / collection destination, name, telephone number, delivery / collection, etc. By specifying only one of the delivery / collection destinations, the specified delivery / collection destination address, name, telephone number, delivery / collection destination
You can display your luggage on the screen,
It is possible to surely carry out the collection work. further,
When all the delivery / collection operations are completed and the collectively registered delivery / collection destinations are no longer needed, the collectively registered delivery / collection destinations can be erased at once. Of course, since they can be deleted individually, the completed delivery / collection destinations can be individually deleted each time the work of one delivery / collection destination is completed.

Further, in the car navigation apparatus of the present invention, since data can be received through the pager connected to the connecting means, the information about the destination point is transmitted by the pager so that the reading means can be read from the storage medium. It is possible to obtain the same action and effect as when read by.

Further, since it is possible to input specific information to a specific car navigation device via a pager, if a business vehicle on the go is to be dispatched to a place that was not scheduled, such a place may be used. Even if the location is unfamiliar to employees, it is possible to register the location where you are going as a destination and display it on the screen, or to display information about the location where you are going on the screen. To rush to a place that was not planned,
It can be performed accurately and surely. Furthermore, it is also suitable for dispatching workers in case of emergency such as gas leak.
