Abstract
A navigation apparatus for displaying map information recorded in a recording medium so that previously stored information is displayed until new information is read and processed from another recording medium when the recording medium is replaced.
Claims8
A navigation apparatus comprising:
- power supply control means for controlling turning on/off of a power supply;
- position measuring means;
- reading means for reading predetermined information including map information and information associated therewith from a recording medium;
- read control means for controlling said reading means to read the map information of a map in a vicinity of a position measured by said position measuring means;
- non-volatile storage means for saving as stored information the predetermined information read by said reading means;
- and
- display processing means for generating a display signal based on one of the predetermined information read by said reading means and the stored information saved in said non-volatile storage means,
- wherein the predetermined information read by said reading means is saved in said non-volatile storage means immediately before said power supply control means turns the power supply off and generation of the display signal based on the stored information saved in said non-volatile storage means is performed when said power supply control means turns the power supply on, and
- when said recording medium is replaced by an other recording medium said display processing means generates the display signal based on the stored information saved in said non-volatile storage means until said display processing means generates another display signal based on another predetermined information read by said reading means from the other recording medium.

A navigation apparatus comprising:
- position measuring means;
- reading means for reading predetermined information including a map information and associated information associated therewith from a recording medium;
- detection means for detecting a loading and removal of the recording medium loaded on said reading means;
- read control means for controlling said reading means to read the map information of a map in a vicinity of a position measured by said position measuring means;
- storage means for saving as stored information the predetermined information read by said reading means;
- and
- display processing means for generating a display signal based on the stored information saved in said storage means,
- wherein when said detection means detects a replacement of the recording medium by an other recording medium said display processing means generates the display signal based on the stored information saved in said storage means until said display processing means generates another display signal based on another predetermined information read by said reading means from the other recording medium.

An automobile loaded with a navigation apparatus comprising:
- power supply control means for controlling turning on/off of a power supply in a part related to a navigation;
- position measuring means for measuring a position of the automobile;
- reading means for reading predetermined information including map information and associated information associated therewith from a recording medium;
- read control means for controlling said reading means to read the map information of a map in a vicinity of a position measured by said position measuring means;
- non-volatile storage means for saving as stored information the predetermined information read by said reading means;
- display processing means for generating a display signal based on one of the predetermined information read by said reading means and the stored information saved in said non-volatile storage means;
- and
- display means for displaying an image based on the display signal generated by said display processing means,
- wherein the predetermined information read by said reading means is saved by said non-volatile storage means immediately before said power supply control means turns the power supply off, and
- a generation of the display signal based on the stored information saved in said non-volatile storage means is performed when said power supply control means turns the power supply on, and
- when said recording medium is replaced by an other recording medium said display processing means generates the display signal based on the stored information saved in said non-volatile storage means until said display processing means generates another display signal based on another predetermined information read by said reading means from the other recording medium.
