<A> Overview of Navigation System The navigation system according to the present invention, on an information recording medium such as a CD-ROM on which gourmet information is recorded, stores, for example, service information such as an ABC ramen shop and latitude indicating the location of the shop. Longitude information (NE information) is posted to guide interested customers to the shop.

More specifically, as shown in FIG. 1, for example, the navigation system reads gourmet information stored in a CD-ROM, displays it on a display device, displays a large number of gourmet information, and selects "ABC Ramen" from among them. When a customer who is interested in a store inputs the latitude and longitude information of the store, the map information is displayed on a display device, and the guide device guides the customer to the store using a GPS system. In addition,
The input of the latitude / longitude information only needs to be able to recognize the latitude / longitude information without directly inputting a numerical value from a key.
For example, if the image displayed on the screen corresponds to the latitude / longitude information, it is possible to input the latitude / longitude information by specifying the image. Further, if the latitude and longitude information of the shop can be input to the navigation system, the latitude and longitude information need not be displayed on the screen.

As shown in FIG. 2, for example, the navigation system includes an input device 1 for inputting latitude and longitude information and control information, and a reading device 5 such as a CD-ROM for reading an information recording medium 4 on which the latest service information and map information are recorded. A display device 2 for displaying the service information and the map information; an arithmetic processing device 3 for performing these processes and searching; and a guiding device 6 for guiding to the position of the latitude and longitude information by the GPS system.

As shown in FIG. 3, for example, the flow of the navigation system is as follows. The information stored in the information recording medium 4 is searched by the reader 5, and the service information and the map information are read (S1). The read service information is displayed on the display device 2 (S2). When a target store is designated by the input device 1, a map is read from the information recording medium 4, displayed on the display device 2, and the guidance device 6 guides the route to the store (S3). The map information may be stored in a storage unit other than the information recording medium 4. Further, the map information may be transferred to the storage means of the navigation system by communication or from another recording medium.

<B> Information Recording Medium The information recording medium 4 can be a recording medium such as a CD-ROM, a DVD, an IC card, a memory, or an exchangeable recording medium, and can include service information such as gourmet information and travel information. For example, it mainly focuses on steaks and ramen for sale, photos of the exterior of the hotel and pools, and records surrounding articles and menu examples that attract the interest of customers.

In the navigation system of the present invention, for example, in the case of a ramen shop, service information such as the shop name, telephone number, contents, address, etc., a digital map, the latitude of the shop location, Latitude and longitude information for displaying information indicating longitude as a GPS code is stored.

[0015] This GPS code indicates the latitude, degree, minute,
Geographic coordinate display information combining information consisting of 6 to 7 digits consisting of seconds and information consisting of 7 to 8 digits consisting of degrees, minutes and seconds indicating longitude, and It is possible to display a specific position on a map of a display unit such as.

[0016] Therefore, even if the destination is a place that the user does not recognize, or is a frontier where a lot number is not originally attached, the destination can be specifically displayed on the map.

This information is updated in the information recording medium 4 every time the information is updated. Therefore, not only the relocation of the store, but also the change of the product to be handled, the change of the price, and all the information that the advertiser wants to update in the printed matter are updated and accumulated as they are.

Further, since the advertisers who do not provide information on the latest information recording medium 4 have been deleted, there is no waste in searching for a store that closed last week, for example.
No distrust of the information recording medium 4 occurs.

<C> Input Device The input device 2 can use input means such as a controller, a keyboard, a touch panel, a mouse, and voice input means.
In addition to inputting the latitude / longitude information, it instructs control of the navigation system. To enter latitude / longitude information, you can directly enter the latitude / longitude value with the controller,
Alternatively, it suffices if the latitude and longitude information can be input to the navigation system, such as by specifying an image on the screen.

<D> Reading Device The reading device 5 can access an information recording medium on which service information and the like are recorded. The reading device 5 searches for service information from the information recording medium 4 based on an instruction from the input device 1. The relevant information is read.

<E> Display Device The display device 2 is a device for displaying information read from the information recording medium 4, and employs a liquid crystal display device or the like.

This display device 2 displays latitude and longitude information. At the same time, the service information and the digital map, or only the service information and the information of only the digital map are displayed.

<F> Arithmetic Processing Unit The arithmetic processing unit 3 performs various processes of the navigation system, and can be constituted by, for example, a computer.
