1. A map display device comprising:
- a map-data storage that memorizes map data;
a display unit that displays a map based on the map data memorized in the map-data storage;
an input unit for inputting a phone number having a string of digits, which is grouped into a group of higher digits and a group of lower digits in order;
an entity-data storage that correlates and memorizes a plurality of phone numbers and entity data including position information of a plurality of entities corresponding to the plurality of phone numbers;
an extracting unit that extracts, from the entity-data storage, entity data of a certain entity corresponding to a phone number having a group of lower digits that accords with a group of lower digits of the inputted phone number; and
a display control unit that causes the display unit to display a map including the certain entity based on the position information of the entity data of the certain entity.

Abstract
When a control circuit extracts data of an entity corresponding to a phone number, the control circuit retrieves phone numbers that accord, with respect to lower seven digits of a phone number, with the inputted phone number from among phone numbers included in retrieval data. After the entity having the phone number corresponding to the inputted phone number is extracted, a map including the entity extracted is displayed based on the position information of the entity extracted. Accordingly, even when the area code of the phone number is changed, the map including the corresponding entity can be displayed.

7. A map display device of comprising:
-
a map-data storage that memorizes map data; a display unit that displays a map based on the map data memorized in the map-data storage; an input unit for inputting a phone number; an entity-data storage that correlates and memorizes a plurality of phone numbers and entity data including position information of a plurality of entities corresponding to the plurality of phone numbers; an extracting unit that extracts, from the entity-data storage, entity data of a certain entity corresponding to a phone number that accords, with respect to a group of lower digits of a phone number, with the inputted phone number; and a display control unit that causes the display unit to display a map including the certain entity based on the position information of the entity data of the certain entity, wherein the extracting unit searches the entity-data storage for entity data of a given entity corresponding to a phone number that entirely accords with the inputted phone number, and wherein, when the entity data of the given entity is not found, the extracting unit extracts, from the entity-data storage, entity data of a entity corresponding to a phone number that most closely accords with the inputted phone number.

8. An entity retrieving method that uses a phone number and is provided in a map display device that includes:
-
a map-data storage that memorizes map data; a display unit that displays a map based on the map data memorized in the map-data storage; an input unit for inputting a phone number; and an entity-data storage that correlates and memorizes a plurality of phone numbers and entity data including position information of a plurality of entities corresponding to the plurality of phone numbers, each phone number having a string of digits grouped into a group of higher digits and a group of lower digits in order, the method comprising steps of; extracting, from the entity-data storage, entity data of a certain entity corresponding to a phone number that accords, with respect to a group of lower digits of a phone number, with the inputted phone number; and causing the display unit to display a map including the certain entity based on the position information of the entity data of the certain entity. - View Dependent Claims (9)
