Description:
BACKGROUNDS OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a map information providing device, a map information providing system, a map information providing method, and a recording medium with a map information providing program recorded therein, and more particularly, it relates to a map information providing system, a map information providing device, a map information providing method, and a recording medium with a map information providing program recorded therein, for providing a user terminal device with map information through a network, especially such as the Internet.  
           [0003]    2. Description of the Related Art  
           [0004]    Heretofore, when a user wants map information through a network such as the Internet, for example, a user gains access to a home page opened by a map information provider on a network and enters the name of a shop or a company, the address, or the zip code, that is the destination whose map information the user wants, as a retrieval condition from a user terminal device. On the side of a map information providing device, the map information is retrieved according to the entered retrieval condition, and the retrieval result is sent to the user terminal device. Then, the user selects his or her destination from the retrieval result, and the map information of the destination is sent to the user terminal device and displayed there. When a user wants the map information on several destinations, he or she gets the map information of every destination one by one by repeating the above operation. Such a retrieving and providing method of the map information is also disclosed in, for example, Japanese Unexamined Patent Publication (Kokai) No. Heisei 11-212999.  
           [0005]    On a map to be provided, apart from the public facilities, there appear only the shops and the companies which make a contract with the map information provider to be published on the map and pay for the contract. Accordingly, the retrieval object is restricted to the above shops and companies paying for the contract fee to the map information provider.  
           [0006]    The above conventional technique, however, is defective in a service for a user because the retrieval object in the map information is very restrictive, limited to the shops and companies paying for the contract fee to the map information provider.  
           [0007]    When a user wants the map information about several destinations, since the map information is provided one by one as for every destination, the conventional technique cannot display the several destinations on the same map and improve a user&#39;s convenience so as to select a destination.  
           [0008]    Further, since only a destination is displayed on the map information to be provided, it is defective in that a user&#39;s current position, and the positional relation and the distance between a reference point like a user&#39;s house and a destination cannot be confirmed on the same map.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0104]    The preferred embodiment of the present invention will be discussed hereinafter in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be obvious, however, to those skilled in the art that the present invention may be practiced without these specific details. In other instance, well-known structures are not shown in detail in order to unnecessary obscure the present invention.  
         [0105]    At first, the first embodiment of the present invention will be described. FIG. 1 is a block diagram showing a structure according to the first embodiment and the second embodiment.  
         [0106]    Referring to FIG. 1, the first embodiment of the present invention comprises a user terminal device  10 , a map information providing device  20 , and a network  30  such as the Internet for connecting both with each other.  
         [0107]    The user terminal device  10  is an information processing device, for example, like a personal computer, which comprises an access/input unit  11  such as a keyboard or a pointing device for entering necessary information through access to the map information providing device  20 , a display unit  12  such as a liquid crystal display for receiving and displaying the information sent from the map information providing device  20 , and a destination identification information storing unit  13  for temporarily storing the identification information of a destination a user selects from retrieved list information.  
         [0108]    The map information providing unit  20  is an information processing device, for example, such as a workstation server, which comprises a destination identification information retrieving unit  21 , a destination identification information storing unit  22 , a billing checking unit  23 , a billing processing unit  24 , a map information creating/sending unit  25 , a map information database  26 , a pay destination database  27 , and a user billing information database  28 .  
         [0109]    The destination identification retrieving unit  21  retrieves the identification information of a destination from the map information database  26  according to a retrieval condition of the destination sent from the user terminal device  10 . The retrieval condition sent from the user terminal device  10  may be specified, for example, by a single item of the name (company name, shop name, and the like), address, zip code, area, and business type, or by a combination of some items (a combination of xx department store and Tokyo or a combination of Indian restaurant and Sinjuku). The identification information of a destination retrieved according to the above retrieval condition is the information including, for example, the name of a destination, the address, and the telephone number. When xx department store Ginza, Shibuya, and Ikebukuro are found as the result of retrieval according to the retrieval condition of xx department store and Tokyo, the name, the address, and the telephone number of each shop are sent to the user terminal device  10  as the identification information of the retrieval result.  
         [0110]    The destination identification information storing unit  22  receives and stores the identification information of the destination a user selects after the identification information of the retrieval result is sent to the user terminal device  10  by the destination identification information retrieving unit  21 .  
         [0111]    The billing checking unit  23  retrieves the pay destination database  27  based on the identification information of the destination a user selects, and checks whether the destination is a pay destination or a free destination. When it is a pay destination, it retrieves the user billing information database  28  based on a user ID number received from the user terminal device  10 , so to check whether or not this user is under a contract of monthly fixed charge, thereby deciding whether the map display this time should be charged or not. The free destination means the public facilities and the shops and companies paying for the contract fee, while the pay destination means the destination a map information provider originally adds to a map.  
         [0112]    The billing processing unit  24  bills a user under a contract of monthly fixed charge once a month (for example, at the end of a month), and bills some other user for a predetermined charge every time providing him or her with the map information of a pay destination. In this case, a charge may be fixed, depending on the number of the pay destinations or regardless of the number of the pay destinations. The details of the payment from a user&#39;s account of a financial institute are well known, and the description thereof is omitted because it is not the purpose of the present invention.  
         [0113]    The map information creating/sending unit  25  retrieves the map information database  26  according to the identification information of the destination sent from the user terminal device  10 , to receive the map information corresponding to the destination, and provides it to the user terminal device  10 .  
         [0114]    The map information database  26  stores map image data in correspondence with the map number and the coordinate number, as the map information, and stores the name of each pay destination and free destination displayed on a map, in correspondence with the items of address, zip code, area, and business type, as well as with the map number and the coordinate number. As the map image data, that one including the pay destinations (the destinations a map information provider originally adds to a map) and the free destinations (public facilities, and the shops and companies paying for the contract fee) is created and stored in the map information database  26 .  
         [0115]    The pay destination database  27  stores the identification information of the pay destinations (the name of a destination, the address, the telephone number, and the like). This information is decided by a map information provider and registered into the pay destination database  27  in advance. On the contrary to the free destinations that are the shops and the companies with which a map information provider makes a contact to be published on a map and which pay for the contract fee, the pay destinations are destinations which a map information provider originally adds to a map, without making a contact with anyone or without income of the contract fee, and instead, a charge of use can be collected from a user when providing the user with the map information of a pay destination. Thus, a map information provider can improve income and a user can find his or her destination more easily in the wider range of the retrieval objects.  
         [0116]    The user billing information database  28  stores the respective billing information corresponding to the user ID number for every user. The billing information means the information whether or not the billing for a user&#39;s receiving the map information of a pay destination is under a contract of monthly fixed charge and the settlement information including the account number of a financial institution and the amount of a bill.  
         [0117]    This time, an operation according to the first embodiment of the present invention will be described with reference to FIG. 1 and FIG. 2. FIG. 2 is a flow chart showing the operation of the first embodiment of the present invention. In the following description, assume that the network  30  is the Internet.  
         [0118]    A user gains access to the home page opened by a map information provider on the network  30  from the access/input unit  11  and enters the retrieval condition of a destination whose map information a user wants to display (Step A 1  of FIG. 2).  
         [0119]    The destination identification information retrieving unit  21  of the map information providing device  20  receives the retrieval condition entered in Step A 1 , retrieves the identification information of the destination from the map information database  26  according to the retrieval condition, and sends the list information of the retrieval result to the user terminal device  10  (Step A 2 ).  
         [0120]    A user selects the destination he or she wants, from the list information of the received retrieval result, through the access/input unit  11  of the user terminal device  10 , and stores the selected identification information into the destination identification information storing unit  13  (Step A 3 ). When the selection of the destination is finished, the user enters the user ID number through the access/input unit  11  (Step A 4 ) and pushes, for example, a complete button on the home page, hence to send the identification information of the destination stored in the destination identification information storing unit  13  in Step A 3  and the user ID number entered in Step A 4  to the map information providing device  20 , before deleting the identification information of the destination identification information storing unit  13  (Step A 5 ). Since the user ID number is the number to be given to every user after a billing contract with a user to receive a map information service of the pay destinations, a user who is not under the contract cannot enter anything at this time. Therefore, on the home page, there is displayed a message to the effect that a user who has not made a billing contract to receive the map information service of the pay destinations doesn&#39;t have to enter the user ID number.  
         [0121]    The billing checking unit  23  of the map information providing device  20  temporarily stores the identification information of the received destination into the destination identification information storing unit  22 , and retrieves the pay destination database  27  to check whether the identification information of the received destination corresponds to a pay destination. Then, it stores the destination identification information with specification of a free destination or a pay destination, into the destination identification storing unit  22  (Step A 6 ).  
         [0122]    When the destination proves to be a pay destination as the retrieval result in Step A 6 , the billing checking unit  23  confirms whether the user ID number has been sent from the user terminal device  10  (Step A 7 ), and when it is a free destination, this step will be advanced to Step A 20 .  
         [0123]    When it proves that the user ID number has been sent in Step A 7 , this step will be advanced to Step A 15 , while when it has not been sent, contract screen information for the map information service of the pay destinations is sent to the user terminal device  10  (Step A 8 ).  
         [0124]    The contract screen information is displayed on the user terminal device  10 , and there is displayed a message to the effect that a billing contract is necessary because the destination a user selects is a pay destination (Step A 9 ). This induces a user to select whether or not to make a billing contract to receive the map information service of the pay destinations (Step A 10 ).  
         [0125]    When a user selects that he or she doesn&#39;t make a billing contract in Step A 10 , the user enters the contract data through the access/input unit  11  (Step A 11 ). The contract data means the information whether billing for receiving a map information service of the pay destinations is under a contract of a monthly fixed charge and the settlement information including the account number of a financial institution for drawing a charge.  
         [0126]    The billing checking unit  23  creates a user ID number newly by receiving the contract data from the user terminal device  10  and sends the same number to the user terminal device  10  (Step A 12 ). The user terminal device  10  displays the sent user ID number (Step A 13 ), thereby enabling a user to use this user ID number at the next access to the map information providing device  20  and the later.  
         [0127]    Continuously to Step A 12 , the billing checking unit  23  registers the contract data sent from the user terminal device  10  into the user billing information database  28  in correspondence with the user ID number (Step A 14 ).  
         [0128]    Thereafter, the billing checking unit  23  checks the necessity of billing, referring to the contract data including the information whether the billing for receiving the map information service of the pay destinations is under a contract of a monthly fixed charge (Step A 15 ). In the case of the contract of the monthly fixed charge, it decides that the billing is not necessary because it should not be required every time, and this step is advanced to Step A 20 . On the other hand, when the billing is not under a contract of a monthly fixed charge, it decides that the billing is necessary because it should be required every time, and sends a message to the effect that you are charged, for example, your charge is ΔΔ yen, to the user terminal device  10  (Step A 16 ).  
         [0129]    The user terminal device  10  displays the message to the effect that you will be charged (Step A 17 ), and a user enters whether he or she pays for the charge or not (Step A 18 ). When the user selects No in Step A 18 , the connection is broken; when the user selects Yes, the billing checking unit  23  registers a predetermined charge in the user billing information database, as the data on the amount of a bill corresponding to the user ID number of this user, and passing the user ID number to the billing processing unit  24 , asks the unit  24  for the billing processing. The billing processing unit  24  performs the billing processing for drawing a charge from a user&#39;s account with reference to the user billing information database  28  (Step A 19 ). Since this drawing processing of a charge from a user&#39;s account of a financial institution is well known and it is not the purpose of the present invention, the detailed description is omitted here.  
         [0130]    The map information creating/sending unit  25  retrieves the map information of a destination from the map information database according to the identification information of the destination temporarily stored in the destination identification information storing unit  22 , continuously to Steps A 6 , A 15 , and A 19 , sends it to the user terminal device  10 , and thereafter, deletes the identification information of the destination temporarily stored in the destination identification information storing unit  22  (Step A 20 ). The user terminal device  10  displays the map information of the destination on the display unit  12  (Step A 21 ).  
         [0131]    The second embodiment of the present invention will be described in detail with reference to the drawings.  
         [0132]    This embodiment is different from the first embodiment of the present invention in that a plurality of destinations are displayed on the same map. In the first embodiment, since each destination is displayed one by one, if a user selects no payment for the charge of a pay destination, the connection will be broken. In the second embodiment, however, if a user selects no payment for the charge, the map information excluding the pay destinations from a plurality of destinations will be provided, differently from the first embodiment.  
         [0133]    The structure of the second embodiment is almost the same as that of the first embodiment shown in FIG. 1. In detail, however, the following points are added to the map information creating/sending unit  25  and the map information database  26 .  
         [0134]    When a user selects no payment for the charge of a pay destination, the map information creating/sending unit  25  provides the user terminal device  10  with the map information excluding the display of the pay destinations. As described later, the pay destinations are distinguishable from the free destinations, for example, in the color of display and the form of a character. Accordingly, the data corresponding to the above can be deleted distinguishably, thereby providing the user terminal device  10  with the map information excluding the pay destinations.  
         [0135]    The map information creating/sending unit  25  includes processing means (function) for retrieving each map number or each map coordinate number of the respective map information in the identification information of a plurality of destinations from the map information database and calculating each map number or map coordinate number including all the map information. For example, when the map coordinate number of the first destination is X2/Y3 and the map coordinate number of the second destination is X4/Y5, it derives X2 to X4/Y3 to Y5. Therefore, the unit  25  sends the map information of a rectangular area ranging from X2 to X4 in the horizontal axis and from Y3 to Y5 in the vertical axis to the user terminal device  10 , and a user can see the map information including both the first and the second destinations.  
         [0136]    The map information database  26  creates and stores the map information including both the pay destinations and the free destinations, and the pay destinations are displayed in a distinguishable way from the free destinations, for example, in the color of display and the form of a character.  
         [0137]    The operation of the second embodiment of the present invention will be described with reference to FIGS.  1  to  3 . FIG. 3 is a flow chart showing the operation of the second embodiment of the present invention. The operation of the second embodiment in FIG. 3 is different from that of the first embodiment in FIG. 2 in that in FIG. 3, Step B 4  and Step B 20  are added to FIG. 2. The others are almost the same. For the sake of preventing the overlap of the description, the different portions are described here. The reference marks (A 1 ), (A 2 ), and the like in FIG. 3 indicate the respective steps corresponding to those in FIG. 2, and for example, the case of B 1  (A 1 ) shows that Step B 1  in FIG. 3 corresponds to Step A 1  in FIG. 2.  
         [0138]    In the added Step B 4 , whether or not there is any other destination to be retrieved is checked. If there is, the operation of Steps B 1  to B 3  (corresponding to Steps A 1  to A 3  in FIG. 2) is repeated. Thus, the identification information of several destinations selected is stored in the destination identification storing unit  13 .  
         [0139]    In Step B 7 , whether all the received destinations are out of charge or not is checked, and if there is even only one pay destination, this step will be advanced to Step B 8 .  
         [0140]    In Step B 20 , the map information creating/sending unit  25  creates the map information excluding the pay destinations and sends the same information to the user terminal device  10  when a user answers that he or she doesn&#39;t make a contract for use in Step B 11  or when a user answers that he or she doesn&#39;t pay for the charge in Step B 19 . At this time, the map information creating/sending unit  25  retrieves each map number or each map coordinate number of the respective map information from the map information database  26 , out of the identification information of the free destinations stored in the destination identification information storing unit  22 , calculates the map numbers or the map coordinate numbers including all the map information, and receives the map information including all the free destinations from the map information database  26 . For example, by deleting the data indicated in the color of display or the form of a character used for displaying the pay destinations, from the map information, the map information excluding the pay destinations is created.  
         [0141]    In Step B 22 , the map information creating/sending unit  25  creates the map information excluding all the destinations and sends the same information to the user terminal device  10 . At this time, the map information creating/sending unit  25  retrieves each map number or each map coordinate number of the respective map information from the map information database  26 , out of the identification information of the pay destinations and the free destinations stored in the destination identification information storing unit  22 , calculates the map numbers or the map coordinate numbers including all the map information, receives the map information including all the destinations from the map information database  26 , and sends the same information to the user terminal device  10 .  
         [0142]    The third embodiment of the present invention will be described in detail with reference to the drawings.  
         [0143]    This embodiment is different from the second embodiment of the present invention in that the information of a reference point such as a user&#39;s house and a user&#39;s current position is further added and that the reference point and one or several destinations are displayed on the same map.  
         [0144]    [0144]FIG. 4 is a block diagram showing a structure of the third embodiment. The structure of this embodiment is different from the first embodiment shown in FIG. 1 in that a reference point registering unit  14  is further added to the user terminal device  10  of FIG. 1. According to this, the information of the reference point is respectively added to the destination identification information retrieving unit  21  and the destination identification information storing unit  22  of FIG. 1, which are changed to the destination/reference point identification information retrieving unit  21 A and the destination/reference point identification storing unit  22 A.  
         [0145]    An operation according to the third embodiment of the present invention will be described with reference to FIGS.  4  to  6  and FIG. 3.  
         [0146]    At first, the registering operation of a reference point will be described in detail with reference to FIG. 5. FIG. 5 is a flow chart showing the registering operation of a reference point in the third embodiment of the present invention.  
         [0147]    A user gains access to the home page opened by a map information provider on the network  30 , through the access/input unit  11  from the user terminal device  10 A and enters the address information or the retrieval condition of the reference point whose map information the user wants to display (Step K 1  of FIG. 5).  
         [0148]    The destination/reference point identification information retrieving unit  21 A of the map information providing device  20 A receives the address information or the retrieval condition entered in Step K 1 , retrieves the identification information of a reference point from the map information database  26  according to this address information or retrieval condition, and sends the list information of the retrieval result to the user terminal device  10 A (Step K 2 ).  
         [0149]    A user selects a reference point he or she wants from the list information of the received retrieval result, through the access/input unit  11  of the user terminal device  10 A, and stores the selected identification information into the reference point registering unit  14  (Step K 3 ).  
         [0150]    Thereafter, if there is a reference point the user wants to register, Step K 1  to Step K 3  will be repeated (Step K 4 ).  
         [0151]    This time, the operation of the third embodiment of the present invention will be described in detail with reference to FIG. 4 to FIG. 6. FIG. 6 is a flow chart showing the operation of the third embodiment of the present invention.  
         [0152]    The operation of the third embodiment in FIG. 6 is different from the operation of the second embodiment in FIG. 3 in that, in FIG. 6, Step C 5  is added to FIG. 3. The others are almost the same and therefore, in FIG. 6, only the portion different from that of FIG. 3 will be described. The reference marks (B 1 ), (B 2 ), and the like in FIG. 6 indicate the respective steps corresponding to those in FIG. 3, and for example, the case of C 1 (B 1 ) indicates that Step C 1  in FIG. 6 corresponds to Step B 1  in FIG. 3.  
         [0153]    In the added Step C 5 , the identification information of a reference point a user wants is selected from the identification information of the reference points previously registered in the reference point registering unit  14  by the registering operation shown in FIG. 5. Thereafter, the user ID number is entered in Step C 6 , and the reference point, the identification information of the destination, and the user ID number are sent to the map information providing device  20 A in Step C 7 .  
         [0154]    In creating the map information in Step C 21  and C 23 , the map information creating/sending unit  25  creates the map information including both the reference point and the destination.  
         [0155]    The fourth embodiment of the present invention will be described in detail with reference to the drawings.  
         [0156]    [0156]FIG. 7 is a block diagram showing a structure of the fourth embodiment of the present invention, which comprises a computer  40  and a recording medium  50 . The structure of the computer  40  is fundamentally the same as that of the map information providing device  20  of FIG. 1 described in the first embodiment of the present invention. The recording medium  50  stores a map information providing program. The recording medium  50  may be realized by a magnetic disk, an optical recording disk, a semiconductor memory, or the other recording medium. The map information providing program is read by the computer  40  from the recording medium  50 , and the same operation as that of the first embodiment of the present invention can be realized by controlling the computer  40 .  
         [0157]    The fifth embodiment of the present invention will be described in detail with reference to the drawings.  
         [0158]    [0158]FIG. 7 is a block diagram showing a structure of the fourth and the fifth embodiments of the present invention, which comprises the computer  40  and the recording medium  50 . The structure of the computer  40  is fundamentally the same as that of the map information providing device  20  of FIG. 1 described in the second embodiment of the present invention. The recording medium  50  stores the map information providing program. The recording medium  50  may be realized by a magnetic disk, an optical recording disk, a semiconductor memory, or the other recording medium. The map information providing program is read by the computer  40  from the recording medium  50 , and the same operation as that of the second embodiment of the present invention can be realized by controlling the computer  40 .  
         [0159]    The sixth embodiment of the present invention will be described in detail with reference to the drawings.  
         [0160]    [0160]FIG. 8 is a block diagram showing a structure of the sixth embodiment of the present invention, which comprises a computer  60  and a recording medium  70 . The structure of the computer  60  is fundamentally the same as that of the map information providing device  20 A of FIG. 4 described in the third embodiment of the present invention. The recording medium  70  stores a map information providing program. The recording medium  70  may be realized by a magnetic disk, an optical recording disk, a semiconductor memory, or the other recording medium. The map information providing program is read by the computer  60  from the recording medium  70 , and the same operation as that of the third embodiment of the present invention can be realized by controlling the computer  60 .  
         [0161]    In the above-mentioned first to sixth embodiments, although the pay destination database  27  is provided separately from the map information database  26 , the pay destination database  27  may be deleted, and the information of the pay destinations and the free destinations may be attached to the identification information of the map information database  26 .  
         [0162]    In the above-mentioned first to sixth embodiments, the registration of the user ID number may be performed as soon as a user gains access to the home page from the user terminal device  10 .  
         [0163]    In the above-mentioned first to sixth embodiments, although any mark (marking) is not attached to the destinations and the reference points on the map information, the map information creating/sending unit  25  may be provided with means (function) of attaching the marking data to the map information, thereby providing the map information convenient for a user to see.  
         [0164]    Further, in the above-mentioned second, third, fifth, and sixth embodiments, the map information including the free destinations and the pay destinations distinguishable from each other in the color of display and the form of a character is created and stored as the map information in the map information database  26 , and the map information creating/sending unit  25  controls the delete of the data about the pay destinations. Otherwise, two kinds of the map information; one including both the data of the pay destinations and the free destinations and the other excluding the data of the pay destinations may be stored in the map information database  26 , although its capacity becomes large, and the map information creating/sending unit  25  may select one of them.  
         [0165]    In the above-mentioned second, third, fifth, and sixth embodiments, the retrieval whether a destination is the pay destination or the free destination may be also performed in Step B 2  of FIG. 3 and in Step C 2  of FIG. 6, and when a user selects a destination in Step B 3  of FIG. 3 and Step C 3  of FIG. 6 and the destination is the pay destination, a message to this effect may be displayed, so as to inform it to a user in advance.  
         [0166]    In the description of the above-mentioned third and sixth embodiments, although the registration of a reference point is performed in advance, as illustrated in FIG. 5, the retrieval of a reference point may be performed every time continuously to the destination retrieval of FIG. 6, instead of selecting one from the reference points previously registered like in Step C 5  of FIG. 6.  
         [0167]    According to the present invention, not only the destinations of the shops and the companies from which a map information provider receives the contract fee, are provided free of charge, but also the destinations the map information provider originally adds, are provided with a charge. Therefore, it is effective in that a map information provider can expect an increasing income and that a user can find a destination more easily according to the wider range of the retrieval objects.  
         [0168]    According to the present invention, since a plurality of destinations are displayed on the map, it is effective in that a user can grasp the distance and positional relation more easily.  
         [0169]    According to the present invention, since a plurality of destinations, a user&#39;s current position, and a reference point such as a user&#39;s house are displayed on the same map, it is effective in that a user can grasp the distance and positional relation more easily.  
         [0170]    Although the invention has been illustrated and described with respect to exemplary embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without departing from the spirit and scope of the present invention. Therefore, the present invention should not be understood as limited to the specific embodiment set out above but to include all possible embodiments which can be embodies within a scope encompassed and equivalents thereof with respect to the feature set out in the appended claims.
