Description

Map display device

The present invention relates to a map display device for displaying a map of a corresponding point by inputting a telephone number.

In the navigation device, a point such as a destination (destination) or waypoint must be input in order to receive the route guidance. Therefore, various point input methods have been proposed so far, and one of them is a phone number input method for searching a registered coordinate based on a phone number and displaying a map. The telephone number is available separately from the telephone number of a private house, and the telephone numbers of public facilities, gas stations, and other stores can be obtained from information such as advertisement, so it can be effectively used as information when calling out a nearby map. have. In addition, in addition to directly inputting a destination, a point input may be input in order to register in a memory (points of memory points) in advance a point where a home, a frequency of use, and a point desired by a user are previously registered. In any case, when a phone number is input and a map centered on a desired point is desired to be displayed on the screen, an operation of calling up the phone number input screen is generally performed by selecting desired items sequentially from a layered menu screen. need.

For example, an operation example will be described with respect to the case where several points with a high frequency of use are registered based on the telephone number. First, bring up the menu screen and select Register Location. By this selection operation, a point registration input selection screen for selecting an input mode such as telephone number input or address input is displayed. If you select a phone number, a phone number input screen is displayed. When the telephone number is input in this input screen, the coordinate value is searched based on the telephone number, and the surrounding map centered on the coordinate value is outputted and displayed on the screen. Since the point registration is performed by confirming and instructing a point to be registered on this map, the above operation is repeated when registering a plurality of points.

When a phone number is entered and a nearby map centered on a point corresponding to the phone number is called out and displayed on the screen, the phone number cannot be directly entered as described above. As the phone number input screen must be called out through the input selection screen in, multiple selection operations are required along the hierarchy of screens until the phone number is entered. Also, even if you are already displaying a map, if you want to print out a nearby map centered on a new point based on a phone number, you must call up the menu screen again and repeat the above operation. There is a problem that the operation is complicated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, so that a telephone number can be easily input and a desired map can be called out quickly based on the telephone number.

2 is a diagram showing a configuration example of a telephone number data file, FIG. 3 is a diagram showing a configuration example of registration point number data, and FIG. 4 is a diagram showing a configuration example of an address data file.

The telephone number data file stored in the information storage device 3 of the vehicle navigation device is composed of telephone number data, registered telephone number, target data, and point data as shown in FIG. The number and the target data are pointed respectively, and the point data is pointed in the target data. The telephone number data has the data of long distance and local station number, representative branch Tokyo and North latitude, map display scale, registered telephone number address and size, and the branch data includes branch data name and its reading, branch Tokyo and North latitude, map display scale, Each data has a registration point number. As shown in Fig. 3, the registration point number data has information of whether the registration type is a general registration point or a town page, and each piece of data of the type number. As shown in Fig. 4, the address data includes a left-bottom east coordinate and a north latitude data address meshed at a predetermined distance, and the lower left north latitude coordinates and the address name for each point. Each data has its own name and address name can be retrieved from the coordinates of Tokyo and North Latitude.

Therefore, if a telephone number is entered, the name of the barometer is obtained if there is a subscriber number that matches the registered telephone number by searching in the long-distance / local area code of the telephone number data. If there is no subscriber number, the genre name is obtained from the target data. And the point data name of the genre name specified in this genre name. At this time, based on the reading of the point data, the name of the point data is displayed in the order of fifty so that the name of the point data can be easily searched, and the heading by the scroll button is also displayed. When displaying the subscriber name or the branch data name, at the same time, the address name is obtained from the coordinates of Tokyo and North Latitude based on the address data, and the address name is displayed in parallel. In this way, when a subscriber number is searched or when a subscriber number is not searched and a registered point is selected for each genre, each of the neighboring maps around the point is displayed by the point Tokyo, north latitude, and map display scale. However, if the desired point is not registered in each genre point, the neighboring map centered on the representative point set in the suburban / city station number is displayed by the representative point Tokyo, North latitude and map display scale of the telephone number data, Scroll through the map and enter the desired points. Here, the building shape map of this invention can be employ | adopted for the map to display.

Next, the operation will be described. 5 is a view for explaining the overall operation of the vehicle navigation apparatus, Figure 6 is a view for explaining the direct input function of the number by the tenkey, Figure 7 is a transition of the screen according to the direct input function of the number by the tenkey (遷移) Is a figure for explaining an example.

When the program of the route guidance system is started by the CPU 51 of the central processing unit 4, as shown in FIG. 5, the present position is first detected by the present position detecting apparatus 2, and the center position of the current position is detected. The surrounding map is displayed and the name of the current position is displayed (step S101). Subsequently, a destination is set using a telephone number, an address, a facility name, a registration point, or the like (step S102), and a route from the current position to the destination is searched (step S103). When the route is determined, the current position detection device 2 keeps track of the current position and repeatedly executes route guidance and display until it reaches the destination (step S104). If the detour road setting is input before arriving at the destination, the search area is set, the search area is re-searched, and the route guidance is repeatedly executed until the destination is reached as described above.

Next, when the tenkey is operated on the map display screen or the screen other than the input mode of the number / number, the processing shown in Fig. 6 is executed. When the Tenkey is awaited (Step S111), when the Tenkey is input, it is first checked whether the Tenkey is "0" (Step S122), and when it is "0", the telephone number input screen is displayed (Step S113). In the case of "1" to "9" but not "0", the registration point number input screen is displayed (step S114). At this time, the input numerical value is stored as the numerical value of a 1st digit (the most significant digit).

When the telephone number input screen is displayed, the user waits for input of the tenkey again (step S115). When the tenkey is input, the numeric value of the input tenkey is stored (step S117), and it is determined whether or not a predetermined number of digits have been input (step S115). S11), if a predetermined digit has not yet been input, it is further determined whether or not a search key (execution key) has been input (step S118). If the search key has not been entered, the process returns to step S115 to repeat the above-described processing to execute input processing of numerical values relating to the next digit of the telephone number, and to search that the predetermined digit is input in step S117 or step S118. If it is determined that the key has been entered, the pseudo-type position is searched for in the entered series of telephone numbers (step S119). In addition, although a predetermined number of digits or a search key is inputted here, the recognition process of the telephone number is executed. However, the telephone number may be searched even if the search key is not input. For example, in the case where the TenKey is not input even after waiting for a predetermined time, it is of course possible to execute a search by telephone number only with the input numerical string.

When the registration point number input screen is displayed, the input of the tenkey is waited again (step S120), and when the tenkey is input, the previous value is multiplied by 10, i.e., the last value is input to 10 digits. The two-digit numerical value added with the numerical value is set as the registration point number (step S122), and the position is searched based on this registration point number (step S124). In step S121, the ten-key input is waited for a predetermined time (3 seconds). If the ten-key is not input, the previous value is set as the registration point number (one digit) and the position is searched based on this registration point number (step S123). Step S124).

Finally, the position is searched based on the telephone number or the map on which the position is searched based on the registration point number is displayed (step S125). In the case of telephone number input, if there is no corresponding telephone number, the representative position coordinate of the station number of the telephone number (international number + city number + subscriber number) is searched and the surrounding map centered on the representative position coordinate is searched. If there is no corresponding telephone number or registration point number, a message is output.

7 shows a state of transition from the map screen to the telephone number input screen or the registration point number input screen and the searched map screen. If it is assumed to have a ten key consisting of "0" to "9", and each key of "retreat" and "search (execute)", it shifts to the telephone number input screen by a ten key input of "0" on the map screen, and "1". Is shifted to the registration point number input screen by the ten key input of "-" Then, whenever there is a ten-key input, voice is generated.

On the telephone number input screen, the search is started with the "search" key after the 10-digit input or the 9-digit input, and the user waits for 3 seconds to accept the "retract" key after the 10-digit input. If there is no corresponding telephone number (station number), the voice message "There is no corresponding telephone number" is outputted, and the screen is returned to the map screen, and the screen is returned to the map screen by the "retreat" key. In the case of the pinpoint search result, a voice message of `` 0566991111 has been searched '' along with the entered phone number is output, and a voice message of `` shows the surrounding map '' is displayed in combination with the representative location search power by the station number. And the map screen is searched.

On the registration point number input screen, the search starts by entering the second digit within 3 seconds after entering 1 digit, and if there is no corresponding registration point, the voice number "25 is not registered" with the entered number. The message is printed and the screen is returned to the map screen, and the "retract" key is used to return to the map screen. The search result of the registration point changes to the searched map screen by outputting the voice message of "25 registration points have been searched" together with the entered number.

In the general telephone number search method, as described in the above-mentioned prior art and the technical problem to be invented, a menu screen (menu mode) is first selected, and a telephone number input screen (input mode) is selected from the menu. ), Select to switch to the input mode, and enter the number by one digit when the input mode is entered. In the present invention, even in other screens (modes) such as map display mode, route guidance mode, map scroll mode, and other information guidance mode, the user does not perform the transition from the menu mode to the input mode, that is, the input of the telephone number as described above. The step until the mode state is selected can be omitted, and a telephone number or a registration number can be directly input by operation of the tenkey. As described above, the present invention can directly perform input operations by numbers such as telephone numbers, branch registration numbers, and shortcut numbers, so that operability can be improved. In particular, since a navigation device having various functions has many operation items and a plurality of menus exist hierarchically, the operation is very complicated by requiring a large number of steps until a phone number input mode is selected in the menu. However, according to the present invention, it is possible to directly enter a number, so that the operability can be greatly improved.

In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible. For example, the above embodiment has been described in the case where the present invention is applied to a navigation device. However, the invention is not limited to the navigation device. Instead, the user inputs a phone number, searches for a coordinate value based on the phone number, and maps the surrounding map centered on the coordinate value. It can be applied to an information guide device or other map display device that displays or displays a map by registering a specific point in a memory and inputting the point number.

The following describes an embodiment in which the present invention is applied to an information guide apparatus based on a building shape map. Fig. 8 is a diagram showing a first embodiment of an information guide apparatus by a building shape map, Fig. 9 is a view showing a structural example of telephone number data, and Fig. 10 is a view showing a structural example of data of a building shape map.

In Fig. 8, the input device 100 inputs a selection and instruction such as a telephone number, a building area on a building shape map, a guide for information on a building, a search for the degree of surroundings, and the like. Touch panels, pointing devices such as joysticks and mice, and remote controllers combined with display screens are used. The output device 200 is a menu screen, a phone number input screen, a building shape map, a display for displaying a guide information output screen, a printer for printing output, and the like, by the central processing unit 400.

The information storage device 300 includes telephone number data 300a having coordinate values corresponding to each telephone number, information on the shape of each building or facility, and various buildings, and map data having information belonging to the corresponding building including a telephone number. Remember 300b. The telephone number data 300a has a representative point coordinate of each long distance and a local station number and a branch mark of each subscriber number. The map data 300b draws the shapes of buildings (general houses, office buildings, mansions, fire departments, department stores, hospitals, stations, etc.), facilities (towers, parks, amusement parks, sports fields, etc.), bridges, roads, and other buildings. It may be data of a building shape map for display, and may have road map data, house map data, and the like. The data of the building shape map includes a coordinate string consisting of a plurality of coordinate values for drawing and displaying the shape of the building, the name, address (address) of the building, and various kinds of information pertaining to the building, for example, type, height, and composition (residents). ) Also has information such as its telephone number

The central processing unit 400 obtains coordinates from the phone number data 300a by inputting a phone number to determine a predetermined range, searches the phone number from the map data 300b within the range, and retrieves the building of the phone number. The processing for displaying the building shape map centered on the center is executed, and the processing for searching for and guiding the information of the map data 300b is also executed based on the displayed building shape map in parallel. The telephone number search unit 400a of the central processing unit 400 searches the telephone number data 300a based on the input telephone number to obtain coordinates. In addition, the map data search unit 400b determines a predetermined range around the coordinates searched by the phone number search unit 400a and searches for a phone number in the map data 300b. The building shape map display processing unit 400c draws and displays a shape map of the building based on, for example, differences in color, its concentration, their shapes, and the like, based on the type, height, and scale of the structure. Then, a process of drawing and displaying the names of the main shapes on the screen is executed. The search guide processing unit 400d searches and guides or finds various information about the building, for example, a list of names of companies, offices, stores, etc., telephone numbers, and information (peripheral information) around the building. The building is searched for and guided by the shape map.

The specific structure of the telephone number data 300a is, for example, as shown in FIG. 9, in which each of the long distance and the local station number, the representative point Tokyo and the north, and the registered telephone number address and size is shown for the long distance and the local station number n. It has data, and it is possible to search for registered telephone numbers (300a… 1) in the intercity and city station numbers. The registered telephone number has data of subscriber number, Tokyo and North latitudes for the registered telephone number (m).

As a specific data structure of the building shape map stored in the information storage device 300, for example, as shown in Fig. 10A, the data of each of the N pieces of dry matter is stored after the data number N of the dry matter. The data of each building consists of information of the name, address (address), type of building, shape, height, and details of the building. The name of the building is the name of the building if the building is a building, the name of the resident if it is a private house, the name of the resident if it is a facility, the name of the facility if it is a facility, and the name of the road such as "Central Road" and "National Highway No. 1". ) Is the address of the building. The shape of the building has the number of coordinates (n) representing the shape, its coordinate values (x ₀ , y ₀ ), (x ₁ , y ₁ ),. , (x _n-1 , y _n-1 ), and the category includes general houses, mansions, office buildings, shared facilities, roads, and parks. The height is information of the number of floors and the height (m). In detail, for example, in the case of a tenant building, information about each tenant includes the number of names (m) and the name, telephone number, room number, and classification (restaurant, conference store,…) for each tenant, Information on the business content). Therefore, as shown in FIG. 10 (B), coordinate values are sequentially read, connected by lines, drawn and displayed as information on the shape of a building, for example, the planar shape of a building or a house, or the terrain of a park can be output. .

FIG. 11 is a view for explaining the display process of the building shape map by telephone number according to the present invention, FIG. 12 is a view for explaining the display process of the building shape map, and FIG. 13 is for explaining the display process of the building name. 14 is a diagram illustrating an example of a display screen of a building shape map.

Next, the display process of the building shape map by telephone number is demonstrated. When a telephone number is input on the telephone number input screen, as shown in Fig. 11, the coordinates are first searched based on the telephone number (step S1), and a range centered on the coordinates is set (step S2). Here, the telephone number data shown in Fig. 9 is searched, and if there is no point (Tokyo-North) coordinate of the registered telephone number or if there is no registered telephone number, the representative point (Tokyo-North) coordinate is searched, and based on the coordinates, Set the range for retrieving the data of the displayed building shape map. In this case, a narrow search range can be set when the coordinates of the registered telephone number are obtained (Tokyo and North Latitude), but a relatively wide search range is set when the representative telephone number (Tokyo and North Latitude) coordinates does not have a registered telephone number. . Next, the telephone number is searched within the set range (step S3), and it is checked whether or not the telephone number is found (step S4). Here, the telephone number is retrieved from the data of the building shape map shown in FIG. 10. Since the coordinates are retrieved in step S1 and the search range is set based on this in step S2, the phone number is directly selected from the data of the building shape map. You can narrow down the amount of information you are searching for than you do. In particular, in the data of the building shape map shown in FIG. 10, various kinds of information are stored, and when a phone number is directly searched from the data of the building shape map for retrieving a phone number from the detailed information having a large amount of information, the time required for searching is very long. However, the search time can be reduced by using the present invention, and the information stored in the detailed information can be used for the branch search. If the telephone number is found, the center position of the building shape in which the telephone number is registered is set as the map center coordinate (step S5). If the telephone number is not found, the coordinate retrieved from the telephone number is set as the map center coordinate ( Step S6), the building shape map and a name are shown (step S7). In this way, since the coordinates are searched from the telephone number data based on the telephone number, the search range is set based on the coordinates, and the data of the building shape map is searched, an unnecessary search can be omitted from the data of the building shape map. As a result, you can search phone numbers efficiently and speed up the search. In addition, since the point can be searched using the detailed information of the building, the point search with high search accuracy can be performed.

As described above, the building shape map is drawn and displayed by sequentially reading the coordinate sequence stored as the shape data in the data of the building shape map and connecting them by a line, and displays the name thereon. As shown in Fig. 12A, the display processing of the building shape map is performed by searching and reading the data of the building shape map within the display range from the map data 300b of the information storage device 300 (step S11). The display aspect of the to-be-dried thing shape is determined (step S12). This display mode is the color of the shape to be displayed, the density | concentration, these shapes, etc. as above-mentioned, and is determined based on a kind, height, and scale of a structure. For example, the classification can be classified into public facilities, stations, theaters, art galleries, amusement parks, towers, mansions, buildings other than ordinary houses, and the public facilities are public institutions such as government offices, police stations, public halls, and parks and playgrounds. The building can be distinguished by public facilities such as buildings, and buildings other than ordinary houses can be distinguished by height (number of floors) or tenant tenants. After determining the display mode in this manner, the building shape map is displayed (step S13) and displayed as the display mode in which the shape is determined (step S14).

For example, as shown in Fig. 12B, the display mode in Step S12 can be determined by referring to the data of the building shape map to be displayed and the display mode determination table as shown in Fig. 12B. In FIG. 12 (B), when the building to be displayed is a public facility, it is classified as a color, and when there is detailed information, it is divided into b shades of color according to its size. In the case of more than predetermined, it is an example which set display modes, such as a color, its density | concentration, these shapes, etc. corresponding to the magnitude | size of a kind and height structure like a c-color net shape. Therefore, in the case of using this display solar determination table, the following processing is performed in step S12. As shown in Fig. 12 (C), the data of each dry shape map is referred to the display state determination table (step S21). First, it is examined whether or not it is a public facility by type (step S22), and in the case of a public facility, it is displayed. The sun is determined to be a color (step S23). If it is not a public facility, it is examined whether or not there is detailed information (step S24). If there is detailed information, it is determined by the name of whether or not the number is α or more (step S25). ), the display mode of the thing below (alpha) is determined to be light b color (step S26). Further, even when there is no detailed information, the height of the dried product is further examined (step S28), and the display state is determined as a c-color net shape that is equal to or greater than a certain height (step S29). In the case of this example, whether or not it is a public facility is a top priority, followed by detailed information, namely, the construction scale of a building, and finally the display sun is determined by the height. In the case of blast furnaces or parks, there are no heights or details.

Since the names displayed on the building vary in length (characters), not all names can be displayed depending on the size of the screen and the range to be displayed. Here, as described above, the priority based on the type, the priority based on some of the detailed information, and the like are set and displayed in a non-overlapping range. 13 shows an example of the processing. First, names are stored in order of magnitude of the number of names m in the detailed information among the data in the range to be displayed (step S31). Subsequently, for all names stored in the order of the number of names m, the display range on the map is calculated (step S32), and the display range of the already displayed names does not overlap (step S34). Is displayed on the map (step S35). Then, the display range is stored (step S34), and the name is displayed on the map (step S35). Then, the display range is stored (step S36), the process returns to step S32, and the same process is repeated. Here, the display range of the name is determined by dividing the center of the building to both sides according to the number of characters on the basis of the length and width of the character and the character spacing, and stored by the position coordinates of the upper left and lower right of the character string. In addition, the term 'not overlapping with the display range' means that the neighboring names are displayed on one side with a slight gap when judged only by the vertical and horizontal size of the characters and the character spacing, so that the map cannot be easily seen. If so, the processing may be performed to determine that it does not overlap with the display range. The method in this case can be realized by, for example, setting the alphanumeric times of the character size up and down of the character string and the beta times of the left and right as the display range, or setting a predetermined number of characters up, down, left and right as the allowable interval.

The shape of the building becomes the flat shape if the building is a general house, a building, or other building, and the flat terrain if it is a park or a road. However, in the case of a building with a large number of occupants, since there is information on the occupants of the building, and there is a lot of information even in the form of a single building, the information is thus displayed in the display processing of the shape map and the display processing of the building name. Unlike general houses, many buildings and public facilities are marked with shapes that are easy to recognize, and names are preferentially displayed. When names overlap, names are not displayed. In addition, street names and names of public facilities have high priority, so that the names of streets, public facilities, and information in buildings are displayed in order of many names.

Fig. 14 shows a display example of the building shape map. The cursor (KL), marked with a ⊙ in the center of the map, highlights the shape of the building in the center, and the names of major buildings such as public facilities, parks, and street names. In addition, what is indicated by several patterns of each building is that display modes are displayed differently, and in the case of color display, since it can distinguish and display by color, density, or a combination of these shapes, data type information, height The display mode can be displayed differently according to information, number of detailed names, and the like. For example, in public facilities such as schools, city halls, and stations, parks, and tenant buildings, buildings with large names can be displayed differently from the normal display state, so that the targets and characteristics of the area displayed as a map can be easily understood. .

Next, the search and guidance using the building shape map will be described. FIG. 15 is a view for explaining a search guide process using a building shape map, FIG. 16 is a view showing an example of a screen at the time of a building selection operation using a building shape map, FIG. 17 is a view showing an example of an information display screen, and FIG. 18 Is a diagram showing an example of an information guide screen by a building shape map, FIG. 19 is a diagram showing an example of a peripheral information search list display screen of a building, and FIG. 20 is a diagram showing an example of a genre search screen.

In the information belonging to a building, for example, if the building is a building, a search or guide for the specific name, type of business, business content, telephone number, etc. of the tenant, such as a store or an office in the building, can be searched and guided. It is possible. That is, by using the dried shape map as described above, it is possible to search not only the building but also its surrounding information based on the data described in FIG. 10, and also guide the information in each building. For example, on the shape map of the building, a cursor as shown in Fig. 16 is displayed at the center thereof, and the building is selected by inputting an instruction for selecting the building in the input device. Therefore, in the search and guide process, as shown in FIG. 15, the building is waited for selection (step S41). When the building is selected, as shown in FIG. 16, the destination, passing point, memory, information, and peripheral information search are performed. The option of each mode is displayed (step S42). Since the destination, the passing point, and the memory are used for setting the point for the route search when the present invention is combined with the vehicle navigation apparatus described above, the description thereof is omitted here, and each mode of information and surrounding information search will be described below.

In this case, it is checked whether the selection key is information or peripheral information search (step S43). When information is selected as shown in Fig. 15, the number of names of detailed information of the corresponding building data and the respective names are read out. The name list is created, and the information is displayed as shown in Fig. 17 (step S44). If one of these name fields is selected, for example, as shown in Fig. 17, if "AIUE Corporation" is selected (step S45), the address (address), the selected name, telephone number, classification, etc., in the building data are displayed. As shown in FIG. 18, the name, telephone number and address of "AIUE Corporation" are displayed (step S46). The return, destination, passing point, and memory displayed on this screen are operation keys. When such operation keys are selected, each process is executed by an interrupt. In addition, even when an instruction other than the selection of a name field is given, similarly, other processes corresponding to the instruction are interrupted and executed.

In the case where the peripheral information search field is selected in step S43, first, as shown in Fig. 19, in order to specify the search range of the peripheral information, "manufacturing and selling of textiles and fabrics" "dyeing and designing of textiles and fabrics"; … A genre list (classification list) such as the above is displayed (step S47). If a classification (genre) column is selected (step S48), the selected classification is searched in the detailed information of the data to find the distance to the selected building (step S49), and the name within the searched predetermined distance is determined. The files are sorted in a short order, and as shown in Fig. 20, the genre name and the number, and a list of distances from each searched name and search point are displayed (step S50). If one of these name fields is selected (step S51), the address (address), the selected name, telephone number, classification, etc. are read out from the building data as in the case of Fig. 18, and these are displayed (step S52). Here, when a return key is input, the surrounding building shape map centering on this building is displayed. Of course, the building shape map may be displayed using another key not shown, or may be switched to another map such as a road map. In step S48, if the instructions other than the classification column selection and the instructions other than the name field selection are step S51, other processes corresponding to the instruction are interrupted and executed.

By using the information guide device according to the building shape map of the present invention, information on the company, office, store, various organizations, etc. occupied in the building in the building shape map, and the telephone number of the individual company can be examined. In addition, the building can be examined by searching and listing various companies, stores, and various organizations within a certain range from the building. On the contrary, it is also easy to display a building shape map centering on the building by inputting a phone number or name and searching for the name, the phone number in the name of the map data, the name of the detailed information, or the phone number shown in FIG. Can be. Therefore, if you know the name or classification and the alternative location, but do not know the building, you can search for the building, for example, the building in which you live, or you can guide the tenant in which building. .

In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in the above-described embodiment, input using a ten-key consisting of numeric keys of so-called "0" to "9" has been described. However, in the present invention, in addition to the numeric keys, "#", "*", and "C" are used as ten keys. And other symbol keys formed on a telephone or an electronic desk calculator, and may be similarly applied to an operation input of a shortcut dialing combination of these symbol keys and numeric keys, and does not specify the arrangement thereof. . In addition to displaying the information directly on the map by inputting a telephone number, other information may be further searched and displayed based on the coordinates retrieved from the telephone number, and the coordinates retrieved from the telephone number may be displayed by other information such as branch registration information. It may be used as. In addition, the present invention can be applied not only to a vehicle navigation device for guiding a route, but also to various map display devices for guiding general map guide, tourist guide, and other information about a map.

As is clear from the above description, according to the present invention, when "0" of a tenkey is directly input, "0" is stored, and the telephone number is shifted to the telephone number input screen as the head input of the intercity code in the telephone number. The operation of calling up the input screen can be omitted, and the input of the telephone number can be reduced. When Tenkid inputs a number other than "0", the numerical value is stored, and the screen shifts to the registration point number input screen as the entry number of the registration point, thereby simplifying the map search by inputting the telephone number and registration point number. Can be.
