1. A map displaying device comprising:
- a display means for displaying map information stored in a map database;
a search means for calculating a travel time to an arbitrary point accessible from a reference point; and
a time information drawing means for generating travel time information based on the calculated travel time,wherein the time information drawing means displays, in a superimposed manner on a map displayed on the display means, the travel time information by varying a display form of the travel time information in accordance with a scale of the map and/or with a running state of a user'"'"'s vehicle,wherein the time information drawing means displays the travel time information for connecting, by one or more lines, points of a same travel time to one another or points of a same travel time period to one another, andwherein the time information drawing means displays the travel time information by dynamically changing the travel time information such that a number of the one or more lines displayed on the display means is a constant number.

21. A map displaying device comprising:
-
a display means for displaying map information stored in a map database; a search means for calculating a travel time to an arbitrary point accessible from a reference point; and a time information drawing means for generating travel time information based on the calculated travel time, wherein the time information drawing means displays, in a superimposed manner on a map displayed on the display means, the travel time information by varying a display form of the travel time information in accordance with a scale of the map, and wherein the time information drawing means displays the travel time information by changing an interval between displayed travel times such that the interval becomes longer as the scale of the map becomes wider.

22. A map displaying device comprising:
-
a display means for displaying map information stored in a map database; a search means for calculating a travel time to an arbitrary point accessible from a reference point; and a time information drawing means for generating travel time information based on the calculated travel time, wherein the time information drawing means displays, in a superimposed manner on a map displayed on the display means, the travel time information by varying a display form of the travel time information in accordance with a running state of a user'"'"'s vehicle, wherein the time information drawing means displays the travel time information by changing an interval between displayed travel times or between displayed travel time periods such that the interval becomes longer as a traveling speed of the user'"'"'s vehicle becomes slower.
