Abstract

If a destination set on a display 3 is a facility not having connection relation between facilities stored in a facility information DB 84, a scroll direction detecting unit 92 that detects a scroll direction of a map 31 detects a direction instructed for scroll as the scroll direction and a display controlling unit 94 performs scroll of the map 31 in the scroll direction. In addition, if the set destination is a facility having the connection relation between the facilities, the scroll direction detecting unit 92 that detects a scroll direction of the map 31 detects the scroll direction based on the connection relation of the destination and the direction instructed for scroll and the display controlling unit 94 performs the scroll of the map 31 to a position of a facility connected to the destination in the scroll direction.

Claims

1. A navigation device that searches for a route to a destination or provides guidance on a facility as the destination, comprising:

a facility information recording unit that records facilities that can be target for the destination and connection relation between the facilities;

a destination setting unit that sets the destination from the facilities recorded in the facility information recording unit;

a displaying unit that displays a map of a vicinity of the set destination;

an operating unit that is used for a scroll operation of the map;

a scroll direction detecting unit that detects a scroll direction of the map based on a direction operated on the operating unit; and

a display controlling unit that scrolls the map in the scroll direction detected by the scroll direction detecting unit,

wherein, if the destination is a facility not having the connection relation, the scroll direction detecting unit detects the direction operated on the operating unit as the scroll direction and the display controlling unit performs scroll of the map in the scroll direction, and

if the destination is a facility having the connection relation, the scroll direction detecting unit detects the scroll direction based on the connection relation of the destination and the direction operated on the operating unit and the display controlling unit performs scroll of the map to a position of a facility connected to the destination in the scroll direction.

2. The navigation device according to claim 1, wherein

the displaying unit functions as the operating unit, and

the scroll direction detecting unit, if the facility set as the destination is a facility having the connection relation and a start point of a scroll instruction on the operating unit is on the facility displayed by the displaying unit, detects the scroll direction based on the connection relation of the facility and the direction operated on the operating unit.

3. The navigation device according to claim 2, wherein

the display controlling unit displays the facility connected to the facility as the destination so as to be distinguishable as a destination change candidate.

4. The navigation device according to claim 3, wherein

the facility having the connection relation is an interchange of a highway.

5. The navigation device according to claim 3, wherein

the facility having the connection relation is a station connected through a railroad track.

6. The navigation device according to claim 5, wherein

the display controlling unit, if a speed of the scroll operation on the operating unit is equal to or more than a predetermined speed, performs the scroll to a station where a limited express train stops next, the station existing in the scroll direction.
