Field of the Invention The present invention relates to an information display device for displaying the location of a facility on a display device in association with a map. 2. Description of the Related Art Recently, vehicle navigation for recording map information on a CD-ROM or the like, reading the map information, displaying the map information on a display device together with the current position of the vehicle, and guiding the vehicle to a predetermined destination. Equipment is being researched and developed. Such a conventional device, for example, when there is a predetermined facility such as a hotel, a parking lot, a gas station, a car dealer, etc., displays the name and the like on a display device along with a road near the location, for the convenience of the driver. To provide. [0003] However, if the names and the like of each facility are constantly displayed on the display device together with the road, the location of each facility can be known, but the map itself is difficult to see. was there. Also, since various facilities are displayed at the same time, when searching for a predetermined one facility, for example, a gas station, the facilities other than the gas station are also displayed. There was a drawback that it took time. [0004] In order to solve the above problems In order to solve the problems, the present invention is an information display apparatus for displaying the Viewing means MAP based on MAP information, the type of facility a selection menu display means that displays a selection menu for selecting the display unit, a position on the map where the type of facility that is selected is present, the symbol indicating the selected type of the facility, and a Cie symbol display means displays superimposed on the map, the selection menu display means, the ground view
When the symbol is displayed on the display unit while being superimposed on the display unit, the selection menu is deleted from the display unit. According to the operation of the present invention, the selection menu display means displays the selection menu on the display means. [0006] Then, the symbol display means, the position on the map of the facility is the type that has been selected to present, selected type
The symbol indicating the facility, is displayed superimposed on the ground view. At this time, the selection menu display means includes :
When the display unit to display symbols superimposed on maps, is erased from the display means a selection menu. Therefore, the type of facility can be changed by the selection menu.
By selecting, different symbols for each type of facility
The location of the facility can be displayed on a map using

The processor 10 calculates and detects the current location of the vehicle from information of the S device 9 and the like. In response to this information, the processor 6 reads a map including the current location from the CD-ROM 1 and stores the map in the memory 5. The CD-ROM 1 stores maps of a plurality of scales, and the memory 5 stores the maps of each scale including the current location. The processor 6 controls the controller 15 to cause the memory 16 or 17 to write data of a predetermined scale out of the map stored in the memory 5. Memory 1
One of the front sides 6 and 17 is a front side (the side where data is transferred to the memory 20) and the other is a back side (the side where data is not transferred to the memory 20 and new data is written by the controller 15). . The front side and the back side are alternately switched, and writing by the controller 15 is always performed on the back side that does not send data to the memory 20. The processor 6 further controls the controller 15 to draw a vehicle mark on the front side of the memories 16 and 17 in accordance with the current position signal from the processor 10. The memories 16 and 17 are controlled by the controller 15.
In the map drawn in the above, data within a predetermined range centered on the own vehicle mark is converted from parallel data to serial data by a parallel / serial conversion circuit 18, and the color signal is further converted to a high gradation by a color palette register 19. And transferred to the memory 20. Which part of the map drawn on the memories 16 and 17 is transferred is specified by the processor 6 via the offset register 22 and the address counter 23. The processor 6 is also capable of drawing a picture of an intersection or the like recorded on the CD-ROM 1 as an image directly in the memory 20. The image written in the memory 20 in this way is further transferred to the memory 21, and finally the image stored in the memory 21 is output and displayed on the display device 29 via the D / A conversion circuits 26, 27, 28. . Next, the operation of the present invention will be described in detail. First, the operation when the guide key 53 is operated will be described. The processing when the guide key 53 is operated is performed according to, for example, a flowchart shown in FIG.
That is, first, the processor 6 as a menu display means
For example, as shown in FIG. 5, a guide menu is displayed at a predetermined position (near the upper and lower sides in the figure) of the display device 29 by superimposing it on a map. Now, in the CD-ROM 1, as map information, not only line segment data indicating roads, railroads, shorelines, etc., but also hotels, gas stations, car dealers, and parking facilities with different symbols for each facility. Assuming that the symbol data to be displayed is also recorded, these symbols are displayed at predetermined positions together with their meaningful characters (facility type names and the like) as necessary. Next, the presence or absence of an input is determined until a key is input. A touch sensor included in the selection unit is arranged on the screen of the display device 29, and when a display position of each facility is touched with a finger or the like, the touch is detected. Therefore, it is sequentially determined whether a hotel, a parking lot, a gas station, or a dealer is selected. When any one of the facilities is selected, the guide menu is erased by the CPU 6 as a display control means and is superimposed on a map. The symbol of the selected facility is displayed at the location. For example, when a hotel is selected, as shown in FIG. 6, the symbol of the hotel is displayed corresponding to the location on the map. This symbol is the same as the symbol displayed when the guide menu was displayed. Therefore, the operator can almost intuitively select a desired facility only by looking at the symbols without looking at the characters in the guide menu display. At this time, facilities that are not selected are not displayed, so that it is extremely easy to search for a symbol. Conversely, when the guide key 53 is not operated, only the normal map without these symbols is displayed, so that the map is not difficult to see. FIG. 4 shows an example of the structure of a data block when data of these facilities is recorded as map information on the CD-ROM 1. That is, the name of the symbol as the header at the beginning of the block (hotel in this example)
Is arranged. In the following, the address of the memory in which the data of the symbol mark pattern is stored, the number of data in the block, and the data are arranged in this order.
Each data is composed of a data number, coordinates (x, y) on a map, and individual information (for example, an address, a telephone number, a characteristic, and the like). Although the present invention has been described by way of example in which the present invention is applied to a vehicle navigation device, the scope of application of the present invention is not limited to this. As described above, according to the present invention, the selection menu
By selecting the type of facility from the
Map the location of facilities using different symbols for each type
Can be displayed on the display,
Workability can be improved. Further, a symbol is displayed by being superimposed on a map.
Sometimes clear the selection menu, so map the symbol
