  The GPS unit 201 is a unit including an antenna for receiving radio waves from a satellite of GPS (Global Positioning System / Global Positioning System). Based on the radio wave received by the GPS antenna, the GPS unit 201 can generate position information indicating the current position of the mobile phone 200. Further, the GPS unit 201 can generate time information representing the current time based on radio waves from the satellite.

  The display panel 202 is a liquid crystal display that can display an image. The display panel 202 includes a touch panel 206a that can receive an instruction from the user by touching a part of the panel according to a displayed image. Specifically, the display panel 202 is configured by overlaying a transparent touch panel 206a on a liquid crystal display. For example, the user can perform an operation for controlling the display of an image by pressing the surface of the display panel 202 with a finger or moving the finger in contact with the surface of the display panel 202. In this specification, “image” is a concept that includes characters, symbols, and the like in addition to narrowly defined images.

  The voice output unit 203 is a device that includes a speaker, and is a device that can output a message to a user such as route guidance, a melody, and the like by voice. The vibration mechanism 204 is a device that can prompt the user's attention with a predetermined pattern of vibration.

  The input unit 206 includes the touch panel 206a and cursor keys 206b as hardware. The user can input information to the mobile phone 200 not only by touching the touch panel 206a but also by pressing the peripheral part of the cursor key 206b to move the cursor and pressing the center part of the cursor key 206b to perform an ON operation. .

  The communication unit 205 can communicate with the map server 150 and the timetable server 170 via the Internet INT to transmit / receive information. The clock unit 209 outputs current time information indicating the current time in response to a request from the main control unit 210. For example, when the current time cannot be acquired from the GPS unit 201, the main control unit 210 can acquire the current time from the clock unit 209.

  The main control unit 210 is a control unit for controlling each unit of the mobile phone 200. The main control unit 210 can control each unit of the mobile phone 200 based on information input to the mobile phone 200 via the input unit 206. The main control unit 210 includes a CPU 211, a RAM 212, and a ROM 213 that are used for these controls.

  More specifically, the main control unit 210 controls each unit of the mobile phone 200 by executing application software with the CPU 211. For example, the main control unit 210 can transmit data in a predetermined format including the position information generated by the GPS unit 201 to the map server 150 via the communication unit 205. Then, the main control unit 210 can acquire map data from the map server 150 and display the map represented by the map data on the display panel 202.

  The map server 150 includes a communication unit 152, a control unit 154, and a storage unit 155. The map server 150 can communicate with the mobile phone 200 and the timetable server 170 via the Internet INT using the communication unit 152. The storage unit 155 stores a map database 156, a required time database 157, a fee database 158, and a display station database 159. The control unit 154 controls each unit of the map server 150.

  The map database 156 stores map image data transmitted to the mobile phone 200 in order to display a map image on the display panel 202 in the mobile phone 200. The map database 156 stores map image data of various scales in association with scale and position information. The control unit 154 is a map image data of an area requested by the mobile phone 200 based on data representing the location, scale, etc. received from the mobile phone 200, and representing a map image of a predetermined size. Is transmitted to the mobile phone 200 via the communication unit 152.

  The required time database 157 is an average required time between two adjacent stations included in various routes such as various railway companies, bus companies, and shipping companies, and between adjacent express stop stations when using express. Data such as the average required time of the train and the average required time between adjacent express trains when using the limited express. The control unit 154 refers to the required time database 157 based on the data received from the mobile phone 200 and the map server 150, and calculates the time required for movement between two specific stations. For example, the control unit 154 totals the time required for the section that is included between the two stations and can use the express train, sums the time required for the section that can use the express train in the remaining sections, and further, The time required for movement between the two specific stations is calculated by summing the time required and further summing the time required. Since the required time between the two stations calculated based on the required time database 157 is not determined based on the timetable, it is not an accurate required time.

  The charge database 158 stores charge table data for various routes such as various railway companies, bus companies, and shipping companies. Based on the data received from the mobile phone 200, the control unit 154 refers to the charge database 158, calculates a charge required for movement between two specific stations, and transmits the calculated charge to the mobile phone 200.

  The display station database 159 displays, for each scale of the map, various routes such as various railway companies, bus companies, shipping companies, etc., and (i) a display representing the routes and stations in the transfer map of that scale. (Ii) the position of the route or station to be displayed on the map, and (iii) the image data representing the station or route to be displayed. When map data of a transfer map of a certain scale is generated, the display station database 159 is referred to, a route and a station to be displayed on the transfer map are selected, image data representing them and their display positions on the map Information is acquired. The transfer map will be described later.

  In a map of a certain scale, a display indicating a station where the limited express stops may be displayed, and a display indicating a station where the limited express does not stop may not be displayed. In a smaller scale map (a map in which a wide area is displayed), a display indicating a station where the express stops may be displayed, and a display indicating a station where the express does not stop may not be displayed.

  In the display station database 159, the stations that should display the station display on the map are selected in advance from all the stations according to the scale so that the user can easily grasp the positional relationship of each station on the map. . In this way, by defining the station where the required time and the fee from the reference station are to be displayed, a transfer map that allows the user to easily grasp the positional relationship of each station on the map can be displayed.

  In the display station database 159, the route on which the route display is to be displayed on the map is selected in advance from all routes according to the scale so that the user can easily grasp the positional relationship between each route and the station on the map. Has been. By defining the routes to be displayed in this way, it is possible to display a transfer map that allows the user to easily grasp the positional relationship and connection relationship of each station on the map.

  The timetable server 170 includes a communication unit 172, a control unit 174, and a storage unit 175. The timetable server 170 can communicate with the map server 150 via the Internet INT using the communication unit 172. The storage unit 175 stores a timetable database 176. The control unit 174 controls each unit of the timetable server 170.

  The timetable database 176 stores timetable data of various routes such as various railway companies, bus companies, and shipping companies. The control unit 174 refers to the timetable database 176 based on the data received from the mobile phone 200 and the map server 150, information on the departure time of a train near a specific time at a specific station, and the stop station of the train And data including information on the stop time and departure time of the stop station can be created and transmitted to the map server 150 and the mobile phone 200.

A2. Processing to display a map:
FIGS. 2 and 3 are flowcharts showing processing performed in the mobile phone 200, the map server 150, and the timetable server 170 in order to display a map on the display panel 202 of the mobile phone 200. A map is displayed on the display panel 202 by the map display method shown in FIGS. The map displayed on the display panel 202 in FIGS. 2 and 3 is a “transfer map” in which routes and stations are displayed on the map. The routes displayed on the transfer map include subway routes and bus routes that are not displayed on the normal map.

  In step S210a, the user first operates the input unit 206 to request the mobile phone 200 to display a map. Specifically, the user operates the touch panel 206a to instruct the map display application software running on the mobile phone 200 to display, for example, a transfer map centered on the current position. Further, in a state where a map other than the transfer map (for example, a normal map in which a subway or bus route is not displayed) is already displayed on the display panel 202, the same range as the displayed map should be displayed on the transfer map. An instruction to this effect can be given to the map display application software.

  The main control unit 210 of the mobile phone 200 determines the center point of the map to be displayed based on the information input from the user, and sends the center via the communication unit 205 together with an instruction to generate a transfer map. The point information is transmitted to the map server 150.

  In addition, the main control unit 210 of the mobile phone 200 also transmits information on the scale of the map to be displayed to the map server 150. When transmitting the center point and scale information to the map server 150, if the map is not displayed on the display panel 202 of the mobile phone 200, the main control unit 210 uses the predetermined scale information as the map. Send to server 150. On the other hand, in a state where a map other than the transfer map is already displayed on the display panel 202, when the user gives an instruction to the mobile phone 200 to display the same range as the displayed map on the transfer map. The main control unit 210 transmits the center point and scale of the displayed map to the map server 150.

  In step S110a, the control unit 154 of the map server 150 receives information transmitted from the mobile phone 200 via the communication unit 152. Then, the control unit 154 of the map server 150 refers to the map database 156 and the display station database 159 based on the information received from the mobile phone 200, and has the designated center point and scale. Transfer map data corresponding to the screen size of 200 display panels 202 is generated.

  More specifically, the control unit 154 determines the range of the map to be displayed based on the center point and scale information received from the mobile phone 200 and the screen size, and the map image having the range is displayed. Data is acquired from the map database 156. In addition, the control unit 154 refers to the display station database 159 based on the scale information received from the mobile phone 200, determines a route and a station to be displayed on the transfer map, and displays image data representing them. Obtained from the station database 159.

  And the control part 154 superimposes a map image and the image showing a station or a route, and produces | generates the data of a transfer map. Note that the “transfer map” generated at this time does not include the display of the required time and fee from the reference station described later. Thereafter, the control unit 154 of the map server 150 transmits map data representing a transfer map to the mobile phone 200 via the communication unit 152.

  In step S220a, the main control unit 210 of the mobile phone 200 receives map data representing a transfer map via the communication unit 205, and displays the transfer map on the display panel 202.

  FIG. 4 is a diagram showing an example M0a of a transfer map displayed on the display panel 202 of the mobile phone 200 in step S220a of FIG. In this transfer map, as shown in FIG. 4, information on a plurality of routes including subways and stations included in those routes is superimposed and displayed preferentially over other information included in the map data. For this reason, the user can refer to the transfer map displayed on the display panel 202 to easily display the route including the subway in the predetermined area displayed on the display panel 202 and the stations included in the route on the map. Can grasp.

  In the transfer map M0a shown in FIG. 4, the point PP specified by the information from the user is indicated by a cross mark. The transfer map display includes a pin button D01, a current location button D02, and an enlargement / reduction button Sc. The display of these buttons is superimposed on the transfer map received from the map server 150 by the main control unit 210 of the mobile phone 200.

  In the state where the transfer map is displayed, when the pin button D01 is pressed and then a point on the map is designated, a pin is displayed at the designated point. When the map is scrolled, the pin moves with the point specified on the map. By such processing, the user can determine the visited place while leaving a mark on the map.

  When the current location button D02 is pressed while the transfer map is displayed, an arrow mark (see the icon of D02) is displayed at a point corresponding to the current position on the map. In addition, when the current position is not included in the range of the displayed transfer map, the display range of the transfer map moves to a range including the current position. When the actual current position moves, the mark indicating the current position moves to a position that matches the current position on the map. By such processing, the user can determine the visited place in consideration of the current position.

  The transfer map includes display of an enlargement / reduction button Sc. The enlargement / reduction button Sc is a button for changing the scale of the displayed map. When the “+” button among the enlargement / reduction buttons Sc is pressed via the touch panel 206a, a map in which a narrower range is enlarged and displayed is displayed. When the “−” button of the enlargement / reduction button Sc is pressed, a map showing a wider range is displayed. In addition, the user can scroll the map by pointing and moving one point on the map.

  In step S220a of FIG. 2, when the user operates the touch panel 206a to instruct the map to be enlarged or reduced, or when the map needs to be scrolled when the current location button D02 is pressed, Again, information on the map center point and scale information are transmitted from the mobile phone 200 to the map server 150 (see “S1a” in FIG. 2). Then, map data of the transfer map is generated again in the map server 150 (step S110a) and transmitted to the mobile phone 200.

  In step S230a, the user operates the touch panel 206a to designate a reference station on the transfer map. Specifically, the main control unit 210 of the mobile phone 200 determines the station closest to the point on the transfer map designated by the user as the reference station. By performing such processing, the user can designate the reference station without having to designate the station point on the map accurately. The main control unit 210 transmits reference station information to the map server 150 via the communication unit 205.

  In step S <b> 120 a, the control unit 154 of the map server 150 receives the reference station information transmitted from the mobile phone 200 via the communication unit 152. Then, the control unit 154 refers to the display station database 159 from the stations included in the predetermined range centered on the reference station, extracts the stations, and determines the required time and fee from the reference station for those stations. Calculate

  The “predetermined range” that defines the station where the required time and fee from the reference station are calculated is wider than the display range of the transfer map. The “predetermined range” can be, for example, a range centering on the central point of the transfer map and having a size 9 times larger than the display range of the transfer map. In this way, by limiting the stations where the required time and fee from the reference station are calculated to a predetermined range, the load required for acquiring the required time and fee from the reference station is reduced, and the processing time is shortened. be able to. In addition, by setting the predetermined range to a range centering on the display range of the transfer map, the time required from the reference station for the station that the user is likely to display on the display panel 202 of the mobile phone 200 by scrolling Charges can be calculated.

  The control unit 154 refers to the display station database 159 based on the range thus determined, and determines a station for calculating the required time and the fee from the reference station. The station for calculating the required time and fee from the reference station is a station displayed on the map in the transfer map of the same scale as the transfer map displayed on the display panel 202 of the mobile phone 200 at that time. By performing such processing, the processing load can be reduced and the processing time can be shortened as compared with the aspect of calculating the required time and the charge for all stations included in the predetermined range. In addition, it is possible to calculate the required time and fee for a station that the user can display on the display panel 202 of the mobile phone 200 by scrolling.

  The control unit 154 refers to the required time database 157 for the station thus determined, and calculates the required time from the reference station. In addition, the control unit 154 refers to the fee database 158 and calculates the fee required for movement from the reference station for each of those stations.

  The control unit 154 does not calculate the required time by determining a transfer route based on the timetable, but calculates the required time based on the required time database 157 that stores the average required time in advance. . For this reason, the time required from the reference station can be calculated in a short time for many stations.

  In step S130a of FIG. 2, the control unit 154 of the map server 150 calculates the required time and fee from the reference station by referring to the display station database 159 based on the display range of the transfer map generated in step S110a. Among the stations that have been selected, the station that should display the required time and fee from the reference station in the transfer map displayed on the display panel 202 of the mobile phone 200 is determined.

  In step S140a, the control unit 154 of the map server 150 displays the reference station on the transfer map created in step S110a, and the required time and fee from the reference station for the station selected in step S130a. And the required time / charge data for displaying are generated. Then, the control unit 154 transmits the required time / charge data to the mobile phone 200 via the communication unit 152.

  In step S240a, the main control unit 210 of the mobile phone 200 receives the required time / fee data via the communication unit 205 and displays the reference map on the transfer map (see FIG. 4) displayed on the display panel 202. The display of the station and the display indicating the required time and the fee from the reference station for each station displayed on the transfer map are superimposed and displayed. As a result, the main control unit 210 of the mobile phone 200, as shown in FIG. 5, for each station displayed on the transfer map shown in FIG. 4, information on the required time from the reference station and the fee from the reference station. And the information of this will be displayed.

  FIG. 5 is a diagram showing an example M1a of a transfer map displayed on the display panel 202 of the mobile phone 200 in step S240a of FIG. In the transfer map M1a of FIG. 5, the display indicating the reference station includes two marks indicating the front view of the train, a display Ds0 indicating “Tokyo”, a display of a flag mark, and the characters “departure station” And display Dt0 including. In the transfer map display, the “departure station” means a reference station.

  Further, in the transfer map M1a of FIG. 5, two marks showing the front view of the train and a display Ds1 of “Kanda” are displayed as the display of the station selected in step S130a of FIG. . A display Dt1 including a display of a charge of “¥ 170” and a display of a required time of “about 2 minutes” is displayed in association with a display Ds1 representing a station. In addition, two marks representing the front view of the train and a display Ds2 of “Yurakucho” are displayed as the display of the station selected in step S130a of FIG. A display Dt2 including a display of a charge of “¥ 150” and a display of a required time of “about 2 minutes” is displayed in association with a display Ds2 representing a station. Similarly, the displays Ds3 to Ds6 in the transfer map M1a are displays of the stations selected in step S130a in FIG. The displays Dt3 to Dt6 are displays of fees and required times associated with those stations.

  By performing such processing, the user should visit around the reference station, taking into account how much time and fee it can move to the surrounding points starting from the reference station (here, Tokyo Station). A point can be selected and the visit route and order can be determined.

  In step S240a of FIG. 2, when the user operates the touch panel 206a to instruct to scroll the transfer map, the map center point information and the scale information are again transmitted from the mobile phone 200 to the map server 150. It is transmitted (see “S2a” in FIG. 2). In step S130a, the map server 150 generates map data of the transfer map again, and determines a station on which the required time and the charge from the reference station are to be displayed based on the map data of the transfer map. And the process after step S140a is performed.

  In step S120a, the time required and the charge from the reference station are calculated for a range exceeding the range of the transfer map displayed on the display panel 202 of the mobile phone 200 (here, a rectangular range of 9 times in both vertical and horizontal directions). Yes. For this reason, when the map is scrolled within the range, the transfer map can be generated and displayed quickly without calculating the required time and fee from the reference station.

  Although not shown in FIG. 2, in step S240a, when scrolling beyond the range of the station for which the charge and required time are calculated in step S120a is performed, or when enlargement / reduction of the transfer map is instructed, The process proceeds from step S240a to step S120a, and the processes after step S120a are performed again.

  In step S250a of FIG. 3, the user who has seen the transfer map (see FIG. 5) determines a target station from the stations displayed in the transfer map, operates the touch panel 206a, and displays the target station on the transfer map. Is specified. The destination station designation method is the same as the reference station designation method. When the destination station is designated, a time input unit that is an area for inputting the time to leave the reference station is displayed on the display panel 202 (not shown).

  In step S260a, the user inputs the time to leave the reference station in the time input unit. The main control unit 210 of the mobile phone 200 transmits information on the target station and information on the time of departure from the reference station to the map server 150 via the communication unit 205.

  In step S150a, the control unit 154 of the map server 150 transmits the destination station information, the reference station information, and the departure time information from the reference station to the timetable server 170 via the communication unit 152. To do. And the control part 154 inquires the timetable server 170 about the transfer schedule containing the departure time of the vehicle which departs from the reference station, and the arrival time of the vehicle at the destination station.

  In step S310a, the control unit 174 of the timetable server 170 refers to the timetable database 176 based on the information on the destination station, the information on the reference station, and the information on the time of departure from the reference station, and the transfer schedule. To decide. The transfer schedule includes the departure time of the vehicle leaving the reference station and the arrival time of the vehicle at the destination station. Then, the control unit 174 transmits transfer schedule data to the map server 150 via the communication unit 172.

  In step S160a, the control unit 154 of the map server 150 determines the reference station, the destination station, the departure time of the vehicle that leaves the reference station, and the arrival time of the vehicle that arrives at the destination station, which are included in the transfer schedule. The display data of the transfer schedule including the display to be displayed in association with the display of the destination station is generated. At the same time, the generated schedule display data includes a “transfer guide” button for instructing the presentation of a detailed transfer schedule and a “set as departure station” button for newly specifying the target station as a reference station. Includes display. The control unit 154 transmits the generated schedule display data to the mobile phone 200 via the communication unit 152.

  In step S270a, the main control unit 210 of the mobile phone 200 receives the schedule display data via the communication unit 205. Based on the schedule display data, the display including the reference station, the destination station, the departure time of the vehicle leaving the reference station, and the arrival time of the vehicle arriving at the destination station, The transfer map displayed in association with each other is displayed on the display panel 202.

  FIG. 6 is a diagram showing an example of a transfer map M2a displayed on the display panel 202 of the mobile phone 200 in step S270a. In the transfer map M2a in FIG. 6, the display Dt10 including the transfer schedule includes a display of “departure: Tokyo” indicating the reference station, a display of “arrival: Kanda” indicating the target station, and a departure of the vehicle leaving the reference station. It includes a display of “15:30” which is the time and a display of “15:32” which is the arrival time of the vehicle arriving at the destination station. Further, the display Dt10 includes a “transfer guide” button for instructing to show a detailed transfer schedule, and a “set as departure station” button for designating a destination station as a reference station.

  By performing such processing, the user looks at the entire map and examines the visited place on the basis of the approximate required time and fee (see FIG. 5), and in the vicinity of the point that is the candidate for the visited place individually. For the station, it is possible to know the accurate departure time and arrival time based on the actual timetable (see FIG. 6).

  If the “set as departure station” button is pressed in step S270a in FIG. 3, the process proceeds to step S230a in FIG. 2 (see “Na” in FIGS. 3 and 2). In step S230a, the main control unit 210 of the mobile phone 200 determines, as a reference station, a destination station that has been newly designated by the user and that has been used in the previous processing. Then, the main control unit 210 transmits reference station information to the map server 150 via the communication unit 205. The following processing has already been described.

  By performing such processing, the user should consider the next place of visit based on the approximate time and price while looking at the entire map, starting from the previous destination station (reference station). Can do. As a result, it is possible to consider a schedule that continuously goes around a plurality of visited places.

  In step S270a, when the “transfer guidance” button is pressed, the processing in FIGS. 2 and 3 is ended, and the processing shifts to the transfer guidance processing. In the transfer guidance process, based on the timetable database 176 of the timetable server 170, the departure time of the vehicle leaving the reference station, the arrival time of the vehicle at the destination station, the transfer station, the departure time of the vehicle leaving the transfer station, The number of the arrival platform of the vehicle at each station is displayed on the display panel 202 of the mobile phone 200. Detailed description of the transfer guidance process is omitted.

  The input unit 206 in the present embodiment corresponds to an “input unit” in “Means for Solving Problems”. The display panel 202 corresponds to an “output unit”. The main control unit 210 that exchanges various data with the map server 150 and the timetable server 170 to realize various functions related to display on the display panel 202 corresponds to a “control unit”.

  The displays Ds1 to Ds6 in the present embodiment correspond to the “first type display” in “Means for Solving the Problems”. The displays Dt1 to Dt6 correspond to “second type display”.

A3. Variations of the first embodiment:
FIG. 7 is a diagram showing a transfer map M3a displayed in step S240a of FIG. 2 in the modification of the first embodiment. In this aspect, the display of the reference station on the transfer map is different from the first embodiment. Other points of the modification of the first embodiment are the same as those of the first embodiment.

  In this embodiment, the reference station display Dt20 includes a flag mark, but does not accompany the character display of “departure station” (see FIG. 5). The aspects of the display Ds21 to Ds33 of stations other than the reference station and the displays Dt21 to Dt33 of charges and required times are the same as in the first embodiment.

  In the example of the display screen of the transfer map M1a shown in FIG. 5, there are a plurality of routes DL1 to DL4 that do not enter each other in the display range. And those routes do not branch. In the transfer map M1a shown in FIG. 5, station displays Ds1 to Ds6 and charges and required time displays Dt1 to Dt6 are displayed for the stations such as the lines DL1 to DL4. However, in both the first embodiment and the modification of the first embodiment, when there is a route that branches into a range included in the transfer map, in step S240a in FIG. Stations included in the route, and the charges and required time are displayed (see Ds21 to Ds33, Dt21 to Dt33 in FIG. 7). In addition, “each branch of the route to branch” means each branch extending from the branch when the route branches while extending in a direction away from the reference station (reference station).

  By performing such processing, the user can consider various points on the map as candidates for the visited place.

B. Variations:
B1. Modification 1:
In the above embodiment, in step S210a in FIG. 2, the user gives an instruction to the mobile phone 200 to display a transfer map centered on the current position, or the same range as the map already displayed. The example in which the mobile phone 200 is instructed to display the transfer map has been described. However, after the user inputs an instruction to display the transfer map in the map display application software, the user enters the facility name or the telephone number or address of the facility, so that the transfer map centering on the facility is displayed. Can be instructed to be displayed. That is, the user only has to indicate the display of the map together with the input of information that can specify the center position.

B2. Modification 2:
In the above embodiment, after a transfer map that does not include the required time or fee is displayed based on information input by the user, the user designates a reference station on the transfer map (see S220a and S230a in FIG. 2). . Then, a transfer map including the required time and fee from the designated reference station is displayed (see S240a in FIG. 2). However, a transfer map including the required time and fee may be generated and displayed from the beginning without displaying the transfer map that does not include the required time and fee in advance. In this case, the main control unit 210 of the mobile phone 200 determines whether or not the reference station on the transfer map is determined in advance in the mobile phone 200, and if the reference station is determined in advance, Information on the determined reference station is transmitted to the map server 150 via the communication unit 205 (see step S230a in FIG. 2). If the reference station on the transfer map is not determined in advance, the representative station in the area set as a default in the mobile phone 200 is determined as the reference station on the transfer map, and the determined reference Station information is transmitted to the map server 150 via the communication unit 205 (see step S230a in FIG. 2).

  Examples of the case where the reference station is predetermined in the mobile phone 200 include the following examples. When the function of the GPS unit 201 is set to be effective and the current position information is acquired by the GPS unit 201, the station closest to the point of the current position information is determined as the reference station. In addition, the user operates the mobile phone 200 and registers departure stations such as the nearest station to the home and the nearest station to the user ID in advance and is set to use the departure station as a reference station. If so, the departure station is determined as the reference station. Thereby, the reference station on the transfer map can be determined in advance.

  In addition, as a method for determining a default station set in advance on the mobile phone 200 as a reference station on the transfer map, since the reference station on the transfer map is not determined in advance, for example, the following method Is mentioned. A default representative station is set for each major area such as Tokyo, Kyoto, Nagoya, and Osaka. Then, the main control unit 210 of the mobile phone 200 determines a default representative station corresponding to the area of the transfer map displayed on the display panel 202 as a reference station on the transfer map. Thereby, the default representative station corresponding to the area of the transfer map displayed on the display panel 202 can be determined as the reference station. Note that the main control unit 210 of the mobile phone 200 displays the determined reference station information on the display panel 202. Thereby, the user can easily grasp which station is determined as the reference station.

B3. Modification 3:
In the above embodiment, the “predetermined range” (see step S120a in FIG. 2) that defines the station where the required time and fee from the reference station are calculated is centered on the central point of the displayed transfer map. This is a range that is 9 times larger than the range of the map. However, the “predetermined range” that defines the station where the required time and fee from the reference station are calculated is N times (N is an integer of 2 or more) in both the vertical and horizontal directions. Other ranges such as a rectangular range having a circle or a circular range having a radius of a predetermined size centered on the center point of the displayed map may be used.

B4. Modification 4:
In the above embodiment, the fee required for movement between the reference station and the destination station is calculated based on the fee database 158 held by the map server 150 (see step S120a in FIGS. 1 and 2). However, the fee required for movement between the reference station and the destination station may be finally transmitted to the mobile phone 200 when the map server 150 or the mobile phone 200 makes an inquiry to the timetable server 170. it can.

B5. Modification 5:
In the first embodiment, the scale of the map displayed on the display station database 159 that stores information on stations to be displayed, which are determined in advance according to the scale, and the display panel 202 of the mobile phone 200 as an output unit. For the station determined based on the above, an image representing the station, a required time and a fee are displayed (see step S130a in FIGS. 1 and 2). However, the station that displays the image representing the station and at least one of the required time and the fee may be determined by other methods.

  For example, a priority database 159a (see FIG. 1) that stores the display priority of each station is provided. Based on the priority database 159a, a predetermined number (for example, 1) selected from the ones with the highest priority is selected. It is good also as an aspect which displays the image showing a station and at least one of a required time and the said charge about seven or less stations in one transfer map.

  For all stations around the reference station, if the station display, the required time and arrival time display are displayed on the map, the majority of the map will be hidden in the display, and each station will be displayed on the map. The position may not be grasped. However, if it is set as said aspect, such a situation can be prevented. The “predetermined number” can be an arbitrary number such as 5 or 8, and can be determined according to the size and drawing density of the portion of the output unit that displays the map.

  Moreover, it is good also as an aspect which displays the image showing a station, at least one of a required time and the said charge about all the stations included in the range of a transfer map.

B6. Modification 6:
In addition, in the transfer map, the first type display is preferentially displayed for the station where the express stops, and the station where the express stops, and the station where the express stops is from a station where neither the express nor the express stops. Also, the first type display may be preferentially displayed.

  With such an aspect, for all the stations around the reference station, an image representing the station is displayed, so the position on the map of the large station where the limited express stops is an image of the station where the limited express does not stop. It is possible to prevent a situation in which the location of the station on which the express stops stops becoming unrecognizable due to an image of a small station where neither the express nor the express stops.

B7. Modification 7:
In the said 1st Embodiment, both the required time and charge to each station other than a reference station are displayed on the transfer maps M1a and M3a (see FIGS. 5 and 7). However, the information displayed in association with the image representing the station in the transfer map may be either one of the required time to the station and the charge.

B8. Modification 8:
In the above embodiment, map data including various buttons Sc, D01, D02 displayed on the map is generated in the map server 150. However, one or more buttons displayed on the map are not included in the map data generated by the map server 150 and may be superimposed on the map in the mobile phone 200.

B9. Modification 9:
In the above embodiment, the present invention has been described by taking the railway and its station as examples. However, the present invention can also be applied to transportation means other than railways such as bus routes and regular service lines. Further, the present invention can also be applied when using a highway or a toll road in an automobile. In other words, the present invention can be applied to various cases of moving between predetermined points (railway station, bus stop, interchange, etc.) at a predetermined fee.

  That is, the “station” in the embodiment of the present invention includes a railway station, a route bus stop, and interchanges of expressways and toll roads. The "Fee required for moving from the reference station to the station" includes "Fee required for transfer from the reference railway station to the station with the railway" and "Transfer from the reference stop to a certain stop" And “highway fare required for traveling from a standard interchange to a certain interchange”.

B10. Modification 10:
Map image data as image data stored in the map database 156 of the server 150 may be stored as raster data or may be stored as vector data. The map image data transmitted to the mobile phone 200 as a terminal device carried by the user may be raster data or vector data. Further, one of the map image data in the map database 156 and the map image data transmitted to the terminal device can be vector data and the other can be raster data.

B11. Modification 11:
In the above embodiment, the aspect of using the GPS has been described. However, the generation of the current position information is performed by using other satellite positioning systems (SATELLITE NAVIGATION SYSTEM) other than GPS, such as GLONASS (Global Navigation Satellite System) and Galileo. For example, the global navigation satellite system (GNSS) may be used. Further, for example, the generation of position information in the mobile terminal may be performed based only on the base station of the mobile phone. In such an aspect, the mobile terminal may be an aspect that does not include a receiver for a global navigation satellite system. Furthermore, the component which produces | generates position information in a mobile terminal can also be set as the aspect which uses together the system using a several system, for example, the system using a satellite positioning system, and the base station of a mobile telephone.

  In other words, the component that generates location information in the mobile terminal can be based on any principle or system operated by any institution as long as the current location information can be specified. Good.

B12. Modification 12:
In the said embodiment, the map display system contains the map server 150, the timetable server 170, and the mobile telephone 200 as the component. However, the mobile terminal that is carried by the user and that includes the GPS unit may be provided with functions of other components such as the map server 150 and the timetable server 170. Further, the map server 150 and the timetable server 170 may be the same server. The mobile terminal exemplified as the mobile phone 200 in the above embodiment may be a so-called feature phone or a smartphone, and may be a PDA (Personal Data Assistant) or another computer as a device that does not have a telephone function. it can. In other words, the portable terminal may be any device that can be carried by the user and can identify the current position.

  That is, the map display system as the map display device may be one device in which each component is housed in one housing. In addition, the map display system can be configured as two or more devices whose constituent elements are connected to each other via a data communication line. For each function such as a function for generating route data and a function for selecting a specific area, one or more arbitrary functions can be assigned to each device. Each function may be realized by one device, or two or more devices may be realized in cooperation. In an aspect in which two or more components are connected by a communication line, the output unit that outputs information to the user is preferably carried by the user.

B13. Modification 13:
In the above embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. For example, a part of the function of the application software can be executed by the control circuit.

  A computer program that realizes such a function is provided in a form recorded on a computer-readable recording medium such as a magnetic disk or a CD-ROM. The host computer reads the computer program from the recording medium and transfers it to the internal storage device or the external storage device. Alternatively, the computer program may be supplied from the program supply device to the host computer via a communication path. When realizing the function of the computer program, the computer program stored in the internal storage device is executed by the microprocessor of the host computer. Further, the host computer may directly execute the computer program recorded on the recording medium.
