The processor 10 calculates and detects the current position of the vehicle from information of the device 9 and the like. In response to this information, processor 6
The map including the current location is read from the D-ROM 1 and stored in the memory 5
To memorize. 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 the front side (the side where data is transferred to the memory 20), and the other is the 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 when the guide key 53 is operated will be described. When the guide key 53 is operated, the processor 6 superimposes the map on the map, for example, as shown in FIG.
The guide menu is displayed at a predetermined position of the display device 29 (near the upper and lower sides in the figure). Now CD-ROM1
As map information, not only line segment data indicating roads, railways, coastlines, etc., but also symbol data indicating symbols of facilities such as hotels, gas stations, car dealers, and parking lots are recorded. Then, these symbols are displayed at predetermined positions together with the meaning of the characters as necessary. A touch sensor is arranged on the front surface of the display device 29, and when a display position of each facility is touched with a finger or the like, it is detected. Therefore, it is determined whether the hotel, the parking lot, the gas station, or the dealer has been selected. When any one of the facilities is selected, the guide menu is deleted, and the symbol of the selected facility superimposed on the map is displayed. Displayed at the location. For example, when a hotel is selected, as shown in FIG. 5, a hotel symbol 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. Each of the symbols representing facilities of the same kind is provided with relatively simple numbers (numbers), characters, symbols, and the like, which can be distinguished from each other and are continuously related. That is, for example, each hotel symbol has a number such as 1, 2, 3, etc., A,
Characters such as B and C and additional marks which are other symbols correspond to the symbols. When the symbols are displayed in a superimposed manner on the map, the additional marks such as the numbers are also displayed. Since the symbol is displayed at the location of the corresponding facility, the symbol and the number of the facility located outside the map centered on the current position displayed on the screen of the display device 29 are displayed within the range of the screen. Not displayed until becomes. In the embodiment of FIG. 5, the hotel with the number 2 is not displayed because it is located outside the currently displayed map. These numbers correspond to each hotel, and different hotels are not given the same number at least within a predetermined area. Therefore, the user can specify a desired hotel by this number. Needless to say, the same applies to other symbols. When a character or the like is added to a symbol, for example, it can be used as the name of the facility. However, the name is not a simple character in the present invention because it makes the map difficult to see. As shown in FIG. 5, when the selected symbol is superimposed and displayed on the map, the selected symbol is displayed at a predetermined position (near the lower right side in the embodiment) of the display device 29. An operation switch for displaying more detailed information of the indicated facility is displayed (in the embodiment, characters of a list are displayed). When a portion of the list on which characters are displayed is touched with a finger or the like, the touch sensor detects the touch, and the map is deleted from the screen of the display device 29 as shown in FIG. More detailed information about the hotel displayed above is displayed in a list. The more detailed information is, for example, a hotel name, a telephone number, an address, characteristics, and the like. Therefore, the operator specifies the desired hotel by its number in the display state shown in FIG. 5, switches to the display shown in FIG. 6, and looks at the information with the corresponding number, thereby displaying the information of the facility. You can know more detailed information. At this time, the information of the facility that is not displayed on the map is not displayed, so that the information of the desired facility is more easily seen. Also, by using something that has a continuous relationship like a number,
It is easier to find a desired facility from the list. A flow chart for the processor 6 to execute the above operation is as shown in FIG. 3, for example. First, in a state where the map is displayed on the screen, the process waits until a symbol display is instructed. When the display of the symbol is instructed, the position data (coordinates) of the symbol is read, and it is determined whether or not the position is within the range of the display screen (map). When the symbol is located within the range of the map being displayed, the symbol is superimposed and displayed on the map. Further, the symbol number is written in a predetermined stack of the memory 5. Symbols located outside the displayed map are not displayed and their numbers are not written to the stack. After such a step is performed for all facilities (symbols), the system waits until a list display instruction is issued. When the list display instruction is input, the number of the symbol stored in the stack in advance is read, and The data corresponding to the number is displayed. FIG. 7 shows a configuration example of position data when the symbol data of such a facility is recorded on the CD-ROM 1. That is, a number in a symbol of the same kind and an attribute for distinguishing between symbols such as a hotel, a dealer, a gas station, a parking lot, and the like are arranged as a header, and coordinates (x, y) of a position where the symbol is displayed thereafter are displayed. Are located. FIG. 8 shows a configuration example of a data block of more detailed information of each facility. That is, following the number of each symbol, data such as the name of the facility, telephone number, address, and characteristics are arranged. FIG. 9 shows an example of the configuration of a stack.
That is, the number of symbols being displayed in a superimposed manner on the map is arranged first, followed by the symbol number. For example, in the case of the embodiment shown in FIG. 5, the number of displayed symbols is three, and the symbol numbers are 1, 3,
4, the data in the stack is as shown in FIG. As described above, according to the present invention, the selection menu
