Abstract

PURPOSE:To decrease operator's operations and to easily obtain map information by taking all sets of the map information sequentially out of a map information memory part in accordance with map information indices and displaying the information. CONSTITUTION:The position where the corresponding map information is stored is determined from a data base 6 for map retrieval when a map address is assigned and inputted from a keyboard part 3. This map information is taken out of the map information memory part 4 and can be displayed 2 in the same manner as heretofore. The map information index 7 is formed from the data base 6 by a processing unit 1 when the instruction for displaying all sets of the map information is given from the keyboard part 3. The unit 1 takes the map information corresponding to the map address sequentially out of the memory part 4 in accordance with the index 7 and displays 2 the same. The next map information and map address are displayed 11 when the operator pushes the confirmation key of the keyboard part 3 after confirming the map information 12 and the map address 13 by viewing a display image screen 11.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an electronic map search and display device.

(Prior Art) Conventionally, this type of map search and display device has a function of inputting a map number from a keyboard section and displaying map information stored in a storage section in correspondence with this map number on a display section. ing. Most of the map information ranges from thousands to thousands of pages.In order to obtain the desired map information from among these, it is difficult to obtain the desired map information unless you know the correspondence between the map number and the map information. Specify and input the map number one by one until you get it.
Is it necessary to repeat the operation to display the corresponding map information on the display unit? In addition, when checking whether map information is correctly stored in the storage unit as the original, you can specify and input the corresponding map number for each piece of map information, and check the map displayed on the display unit. You may need to check the information.

(Problems to be Solved by the Invention) In the conventional map search and display device described above, in order to display map information on the display section, the map number corresponding to the map information must be entered from the keyboard section. There is a problem in that when the operator wants to obtain map information for which the number is not known or when checking all the map information, it takes time and effort for the operator to perform operations.

(Means for Solving the Problems) In order to solve the above-mentioned problems, a map search and display device provided by the present invention includes a map information storage unit that stores map information, and a map stored in the map information storage unit. a display unit that displays information; a map search database that stores map numbers corresponding to the map information and storage positions of the map information in the map information storage unit; and map information that stores all of the map numbers. It includes an index and a keyboard section for inputting the map number or an instruction to display all of the map information on the display section.

The map search and display device of the present invention, when a map number is input from the keyboard section, determines the storage location of the map information corresponding to this map number in the map information storage section from the search database, and based on this storage location. The corresponding map information is retrieved from the map information storage section and displayed on the display section.

Furthermore, when the instruction is input from the keyboard section,
A map information index is generated from the map search database, and based on this map information index, all of the map information is sequentially retrieved from the map information storage section and displayed on the display section.

Therefore, the map search and display device of the present invention allows the user to input an instruction to display all map information once without having to input map numbers one by one from the keyboard section, and the map information is stored in the storage section. It is possible to sequentially display all of the map information on the display unit.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a map search and display device according to an embodiment of the present invention.

In the figure, 1 is a processing device, 2 is a display section, 3 is a keyboard section,
4 is a map information storage unit, 5 is a magnetic disk, 6 is a map search database, and 7 is a map information index. The map information storage section 4 is realized by an optical disk device. The map search database 6 stores a map number and a storage location in the map information storage unit 4 of map information corresponding to the map number.

In the map search and display device of this embodiment, when a map number is designated manually from the keyboard section 3, the storage location of the map information corresponding to the map number is determined from the map search database 6, as in the conventional case, and the corresponding map Information is retrieved from the map information storage section 4 and displayed on the display section 2.

When an instruction to display all map information is input from the keyboard section 3, the map search and display device of this embodiment generates a map information index 7 from the map search database 6 using the processing device 1.

The map information index 7 is an index for automatically searching all map information, and is an index for automatically searching all map information.
Consists of map numbers corresponding to all map information stored in . The processing device 1 sequentially retrieves the map information corresponding to the map number from the map information storage section 4 based on the map information index 7, and displays it on the display section 2 as shown in FIG.

In FIG. 2, 11 is a display screen, 12 is map information, 1
3 indicates the map number.

After checking the map information 12 and map number 13 by looking at the display screen 11, the operator presses a special key provided on the six-board section 3, such as a confirmation key, to display the next map information 12 and map number. 13 will be displayed on the display screen 11.

(Effects of the Invention) As described above, according to the present invention, all the map information stored in the map information storage section is sequentially displayed on the display section. Therefore, the operator's operations are minimized, and the operator can easily perform these operations when searching for map information to inform the map number or checking whether the stored map information is correct.
