(Sitioning System) and the like, read map data around the current position from a storage medium such as a CD-ROM, display a map image on a display screen, and superimpose a mark of the current position on a predetermined position on the map image. I do. Then, as the current position changes due to the movement, the mark on the screen is moved, or the mark is fixed at a predetermined position such as the center of the screen and the map is scrolled, so that the map information around the current position is always at a glance. I understand it.
When a destination is set, these navigation devices search for an optimal guidance route from the current position to the destination, display the searched guidance route on a map, and provide route guidance to the destination. A guidance function is provided, and even if the user does not know the destination, the user can easily reach the destination by moving along the instruction of the navigation device. In addition, these navigation devices can use a detailed version of a storage medium for each region as a storage medium, so that detailed information and photographs of sightseeing spots and facilities can be viewed on a display screen.

Such an in-vehicle navigation device generally comprises a navigation device main body for performing navigation processing and a display device for displaying an image sent from the main body.

In short, an on-vehicle navigation device cannot be used when a user arrives at a desired destination, such as a tour of a sightseeing spot, and then walks or travels by a public institution (bus or train). . For this reason, the user makes notes or memorizes places to be visited while looking at the screen of the navigation device in a parking lot near the destination, but taking notes is a very troublesome act and forgetting by memorizing. Great potential. On the other hand, a portable navigation device is an integrated device of a navigation device main body and a display, and is not suitable for long-time portable use such as sightseeing spots because it is large and heavy in size. In addition, there is a problem that the price is too high for a portable device because the price is equal to or higher than that for a vehicle. In view of the above, an object of the present invention is to download predetermined navigation information from a navigation device, and to view the navigation information as needed, to provide a small, lightweight, portable card-type portable mobile device. It is to provide a terminal device.
