Map information display apparatus and traveling route display apparatus and route guidance apparatus for moving body
First Claim
1. A map information display apparatus comprising:
- a CD-ROM disc including a recording area for storing map information, character information, and voice information in a hierarchical manner, wherein the map, character, and voice information are each stored at separate hierarchical levels therein, and further including a management information area located on an inner annular area of the recording area having recorded therein discrimination data for discriminating whether the voice information is recorded in the recording area;
CD-ROM read-out means for determining whether the CD-ROM disc has the voice information recorded therein based on the discrimination data recorded in the management information area;
output means for outputting only the map information and the character information corresponding to respective positions on a map when the CD-ROM read-out means determines that the voice information is not recorded in the CD-ROM disc;
display means for displaying the map information and the character information output from the output means;
position designating means including a joystick operable by a user for moving a cursor for designating an arbitrary position on the map displayed on the display means and for selecting a reporting mode; and
converting means for converting the voice information corresponding to the arbitrary position on the map and to a selected reporting mode designated by the position designating means into a voice output signal when the CD-ROM read-out means determines that the voice information is recorded in the CD-ROM disc.

Abstract
A traveling route display apparatus for a moving body such as an automotive vehicle includes a position detecting section, an output section, a display section, and a converting section. The position detecting section detects a current position of the moving body by using a signal transmitted from a satellite. The output section outputs map information including character information corresponding to a position on the map recorded on a recording medium, etc. The display section displays the map information delivered from the output section, and displays, on the map information, the current position of the moving body detected by the position detecting section. In addition, the converting section converts character information corresponding to the current position of the moving body detected by the position detecting section into voice to output it.

4. A traveling route display apparatus for a moving body, comprising:
-
position detecting means for detecting a current position of the moving body; a CD-ROM disc including a recording area for storing map information, character information, and voice information organized in a hierarchical manner corresponding to positions on a map, wherein the character and the voice information are stored at separate hierarchical levels, and further including a management information area located on an inner annular area of the recording area having recorded therein discrimination data for discriminating whether the voice information is recorded in the recording area; CD-ROM read-out means for determining whether the CD-ROM disc has the voice information recorded therein based on the discrimination data recorded in the management information area; user input means including a joystick operable by a user for moving a cursor for designating a reporting mode; output means for outputting only the map information and the character information corresponding to the current position of the moving body on the map when the CD-ROM read-out means determines that the voice information is not recorded in the CD-ROM disc; display means for displaying the map information and the character information output from the output means, and for displaying the current position of the moving body detected by the position detecting means; and converting means for converting the voice information corresponding to the reporting mode and to the current position of the moving body detected by the position detecting means into a voice output when the CD-ROM read-out means determines that the voice information is recorded in the CD-ROM disc. - View Dependent Claims (5, 6, 7, 8, 9)
