Map information display apparatus and traveling route display apparatus and route guidance apparatus for moving body

Claim 2

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.

Claim 3

The map information display apparatus as set forth in claim 1, wherein the converting means includes voice synthesis means for carrying out voice synthesis on the voice information corresponding to the arbitrary position on the map and the selected reporting mode designated by the position designating means.

Claim 4

The map information display apparatus as set forth in claim 2, wherein the converting means includes voice output means for outputting voice synthesized by the voice synthesis means.

Claim 5

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.

Claim 6

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.

Claim 7

The traveling route display apparatus for a moving body as set forth in claim 4, wherein the reporting mode includes a route explanation mode where information corresponding to a description of landmarks in a vicinity of a route set by the user input means is output by the output means and the converting means.

Claim 8

The traveling route display apparatus for a moving body as set forth in claim 4, wherein the reporting mode includes a vehicle position mode where information corresponding to an absolute position on the map detected by the position detecting means is output by the output means and the converting means.

Claim 9

The traveling route display apparatus for a moving body as set forth in claim 4, wherein the converting means includes: voice synthesis means for carrying out voice synthesis on the voice information corresponding to the position on the map detected by the position detecting means; and voice output means for outputting voice synthesized by the voice synthesis means.

Claim 10

The traveling route display apparatus for a moving body as set forth in claim 4, further comprising setting means for setting a route through which the moving body travels using the user input means, wherein the converting means outputs the voice output as route information corresponding to positions in a vicinity of a route set by the setting means.

Claim 11

The apparatus according to claim 4, wherein the reporting mode includes a place-name readout mode where voice information corresponding to a place name corresponding to the current position is output by the converting means.
