BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation input device, for example, a navigation input for inputting position information such as a destination and a starting position to the navigation device by using position information such as a bar code and a G code. Regarding the device.

2. Description of the Related Art Navigation devices for guiding a route to a desired destination or guiding a destination to a driver who is not guided by geography have been widely put into practical use. With this navigation device, when you enter a destination or departure point,
The travel route between these two points is searched, and the route guidance is performed while displaying the travel route, the current position of the vehicle, and the arrow indicating the traveling direction together with the road map on the display device. In this navigation device, by recognizing the position of the destination with the coordinates of latitude and longitude, the route to the destination is searched and the landmark of the destination is displayed together with the map information. However, when inputting a destination, it is difficult for the driver to check and input the latitude and longitude. Therefore, in conventional navigation devices, the destination information such as the name of a public object or the address of the destination is used. The coordinates corresponding to are stored and the driver can input the destination only with the destination information.

In some navigation devices, it is difficult to store the coordinates corresponding to all the destination information, so that the destination or the like is input using a bar code. There is a navigation device described in Japanese Patent Laid-Open No. 6-103498 that uses a bar code. In this navigation device,
A bar code with latitude and longitude data recorded is printed at major points on the map, the bar code is read, and the latitude and longitude data read from this bar code is read. -Enter data as the destination. There is also a navigation device provided with a map in which a bar code is printed for each area, instead of printing a bar code for each destination.

[0004]

However, it was not possible to input a spot other than the spot where the barcode was printed as the destination. In such a case, it is necessary to display the map corresponding to the area range in which the barcode is printed on the navigation device and select and specify the desired destination on the displayed map, making the destination input complicated. Met. It is also possible to increase the number of barcodes printed on the map, but if you increase the number too much, the distance between the barcodes will become narrower and you will not be able to check the original map portion with the barcode. There is a risk of accidentally reading an unintended bar code instead of the bar code and inputting an incorrect destination. Moreover, even if the number of barcodes is increased, it has not been possible to set a space between the barcodes as a destination.

Therefore, it is an object of the present invention to provide a navigation device capable of easily and accurately inputting the position of a destination which is not stored in the navigation device.

Next, the operation of the embodiment configured as described above will be described. FIG. 2 is for explaining the operation of setting the destination by the input device for navigation. As shown in FIG. 2 (a), the map book 51 for bar code input shows a map of a scale of 1 / 10,000, and the map of each page sets the destination such as the destination. Bar codes 52a, 52b, ... Data indicating the latitude and longitude of the center point is recorded in each barcode 52a, 52b, ....

Now, it is assumed that the hotel 53 is set as a point other than the point where the bar code 52a is described as the destination. In this case, the range 54 including the nearest barcode 52a and the hotel 53 is read by the navigation input device 10 as follows. First of all, the operator
Place the reading unit 14 where is placed on the map book 51,
After the reading switch 162 is turned on, the reading range 54 is gently moved in the direction of the arrow 56 to read the map of the reading range 54, and then the reading switch 162 is turned off. The reading range is about 500 m square.

Then, the reading unit 14 converts the read image information of the reading range 54 into digital data, and then R
It is stored in the image information area of AM13. Further, the reading unit 14
The bar code reader (not shown) reads the latitude data and the longitude data recorded in the bar code included in the reading range 54 and stores them in the bar code area of the RAM 13. Now, for example, the latitude data of the center position of the barcode is N35 ° 42′05.55 ″, and the longitude data is E139.
It is assumed that the angle is 43'49.32 ". And the CPU
11 shows a map of the reading range 54 from the image information stored in the image information storage area, as shown in FIG.
It is displayed on the display unit 15. When the reading range 54 becomes vertically long, the CPU 11 displays the reading range 54 by reducing it to a size that can be displayed in the display unit 15, and stores the reduction rate in the RAM 13.

The operator designates the destination by touching the position of the hotel 53 with the pen tip or the finger tip from the map screen displayed on the display section 15. The designated position is detected by the touch panel 161 arranged on the upper surface of the display unit 15, and the coordinate position on the touch panel 161 is stored in a predetermined area of the RAM 13. When the destination is specified, the CPU
Reference numeral 11 is the coordinate position of the barcode on the touch panel 161, its latitude / longitude data, the coordinate of the designated destination on the touch panel 161, and the scale of the map book (1 / 10,000).
Then, the latitude data and longitude data of the destination (for example, N35 ° 42′15.00 ″ as latitude data and E139 ° 43′59.20 ″ as longitude data) are calculated.
