First Claim
1. A travel route searching apparatus, comprising:
- a point storage section for storing one or more pieces of travel point data each including at least one travel point;
a data selecting section for selecting one of the pieces of travel point data stored in the point storage section;
a first point obtaining section for obtaining a start point and an end point that are required for a travel route search;
a cartographic data obtaining section for obtaining cartographic data of an area required for the travel route search; and
a travel route searching section for searching, by using the cartographic data obtained by the cartographic data obtaining section, for a travel route from the start point obtained by the first point obtaining section via the travel point included in the travel point data selected by the data selecting section to the end point obtained by the first point obtaining section.

Abstract
A travel route searching apparatus 1a includes at least a storage unit 11 and a processor 15. The storage unit 11 stores one or more pieces of travel point data including at least one travel point. The processor 15 selects one of the pieces of travel point data from the storage unit 11, and then obtains a start point and an end point that are required for a travel route search. Furthermore, the processor 15 obtains cartographic data of an area required for the travel route search, and then uses the obtained cartographic data to search for a travel route from the obtained start point via the travel point included in the selected travel point data selected to the obtained end point. Thus, it is possible to provide a travel route searching apparatus that requires only a small number of operations for designating travel points.
