2. Description of the Related Art Conventionally, a vehicle-mounted navigation device that guides a vehicle to a destination by performing route guidance according to an operation input by a user has been widely used. When a user inputs a destination or a waypoint, a vehicle-mounted navigation device that performs such route guidance receives GPS (Global Positioning System).
tem) etc. to recognize the current position of the vehicle, select the optimum route from the current position of the vehicle to the destination via the waypoint entered by the user, and display the map required on the display. I'm trying to give guidance.

In such a vehicle-mounted navigation device, a method for a user to input a destination and a waypoint is as follows.
For example, a user can scroll through the map displayed on the display to search for destinations and stopovers, specify the destinations and stopovers on the map, and display a list with the names of major points. In general, a method of displaying a desired destination or a waypoint from the list and selecting the desired destination or transit point from the list.

However, the above method compels the user to perform a complicated operation, which increases the burden on the user. For this reason, various proposals have been made for an in-vehicle navigation device that provides route guidance, which makes it easier to input a destination and a waypoint and reduce the burden on the user. For example, Japanese Patent Laid-Open No. 5-241507. In the official gazette, a bar code corresponding to position information indicating major intersections and tourist attractions is printed on a map book, and the bar code scanner connected to the vehicle-mounted navigation device reads the bar code printed on the map book. Therefore, a technique for inputting a destination and a waypoint is disclosed.

When inputting a destination or a waypoint by reading a bar code printed on a map book as in this example, the map is divided into mesh-like areas of substantially equal size, A bar code indicating the vertical arrangement order and a bar code indicating the horizontal arrangement order are printed for each area, and the two vertical and horizontal bar codes are read to specify the area located at the intersection. Is also effective.

In an in-vehicle navigation device for route guidance, if the destination or waypoint can be designated by the above-mentioned bar code input, the user can perform the input operation of the destination or waypoint very easily. , It will be convenient for the user.
