CROSS REFERENCE  
         [0001]    This application is based upon and claims the benefit of priority from the prior Japanese Application No. 2001-058996, filed on Mar. 2, 2001; the entire contents of which are incorporated herein by reference.  
         BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The present invention relates to an image forming system for receiving image data provided from a server through a network using a portable terminal such as a cellular phone and outputting this image data, and particularly relates to an image forming system of map data, etc.  
           [0004]    2. Description of the Related Art  
           [0005]    In recent years, such portable terminals as cellular phones, etc. have come into socially wide use and various environmental conditions of data equipment are changing at present. There are portable equipment that have a display comprising a small LCD and an electronic mail exchanging function or an internet connecting function in addition to cellular phone communication function.  
           [0006]    On the other hand, many web sites provide various information pages in may fields on the Internet. Many of the information are prepared by assuming that they are displayed mainly on displays of personal computers. However, there are provided less information pages for portable terminals such as cellular phones. Further, pages other than those pages for portable terminals as described above are prepared using image data comprising extremely larger volume of data than test data in many cases.  
           [0007]    Accordingly, when any page other than those for portable terminals on the Internet is read using a portable terminal such as a cellular phone, the page is hardly displayed on a small display of a portable terminal. Moreover, as the memory capacity provided to a portable terminal is small, the memory may become insufficient only when data is received. Further, a system to charge according to volume of data received or transmitted is applied to portable terminals such as cellular phones. Accordingly, when a page data in large volume is received, the communication traffic increases, resulting in drop of communication speed or increase in communication cost.  
           [0008]    There are considerably many map data and route guide services on the Internet. These map data and route guide services need a personal computer. Further, a time is required to print data in advance before departure or a position guide service may not be accessed to on the way even when desired. To solve such troubles, a highly functional PDA (Personal Digital Assistant) and cellular phones that have the Internet access function are considered.  
           [0009]    For example, as technologies presently available, those technologies that are disclosed in Japanese Patent Application Nos. 10-178674, 9-280878, 10-9888, 10-22905, 10-103990, 2000-324542 are pointed out. In Japanese Patent Application No. 10-178674, the data of the point of departure required for the route guide can be obtained using the position data system of PHS (Personal Handy-phone System). This position data is transmitted to a server which in turn prepares route guide data and return it to PHS. However, accuracy of about 100 m only is available from the position data system of PHS and therefore, such a trouble that one alley is mistaken as a place of departure can be expected.  
           [0010]    Further, in Japanese Patent Application No. 2000-324542, it is disclosed that when a destination was input to a data service station installed on a signal pole at an intersection from a portable terminal using a most short distance optical communication function, it is possible to guide around the place wherein the station is installed.  
           [0011]    The above-mentioned technologies are to input a destination or a point of departure using a portable terminal, inquire the data service center using a communication function and display guide data on a portable terminal.  
           [0012]    However, a merit of a timely road guide that is obtained using a terminal carried by a user is undeniable but the map data and route guide services are required to provide such data as a map, a time table, etc. to a user and there is a limit for portable terminal that is not able to provide a large screen. To solve this problem, in Japanese Patent Application No. 10-222527, a system capable of printing data searched by a portable terminal and thus, a portable terminal is able to use by printing map data, route guide service, map and time table that are in large volume.  
           [0013]    However, in the system disclosed in this Japanese Patent Application No. 10-222527, it is necessary to input a destination data and select it from a voluminous printer list. In addition, it is also necessary to search a destination by a cellular phone at a real time near a printer. Further, it is difficult to search several destinations while waiting a coming street-car or a bus and obtain a guide map by printing these data collectively using a printer available at a place where get off a streetcar or a bus or to input data in a preceding day and print on the day.  
         SUMMARY OF THE INVENTION  
         [0014]    It is an object of the present invention to provide an image forming system and an image forming apparatus using a cellular phone, which enables extremely free operability when printing and outputting map data, etc. on a network by separating the operation through a cellular phone time-wise from the operation through a terminal printer.  
           [0015]    According to the present invention, there is provided an image forming system comprising a portable terminal connected to a network through a radio communicaition to transmit a desired destination data via the network by the operation of a user; a server connected to the network to receive the destination data from the portable terminal via the network and store the destination data in a prescribed area; and an image forming apparatus connected to the network to receive map data comprising a position data of the image forming apparatus as a starting point and the destination data stored in the server as an ending point via the network, and form a map image on a recording medium based on the map data.  
           [0016]    Further, according to the present invention, there is provided an image forming apparatus in an image forming system including a portable terminal that is connected to a network through a radio communication, a server and the image forming apparatus that are connected to the network, comprising a data supply unit that is connected to the server through the network according to user&#39;s operation and supplies a position data of the image forming apparatus and a data to designate destination data stored in a prescribed area to the server; and an image forming unit that is supplied with a map data comprising a position data of the image forming apparatus as a starting point and the destination data as an ending point from the server and according to the supplied map data, forms an image on a recording medium.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0028]    An image forming system and an image forming apparatus in the embodiment of the present invention will be described below in detail referring to attached drawings.

         [0029]    &lt;Structure of Image Forming System&gt; 
         [0030]    The image forming system in the embodiment of the present invention is a portable terminal that has a function to make the access to the Internet N through the radio communication as shown in FIG. 1. In this embodiment, the explanation will be made using a cellular phone  11  as a portable terminal; however, not restricted to this but other portable terminals that are connectable to the Internet N such as portable mail terminals or PDA (Personal Digital Assistance) are usable. The cellular phone  11  has a gateway  12  of a communication carrier that makes the radiocommunication. The gateway  12  has a function to communicate with other cellular phones and a function to connect to the Internet N. Thus, the cellular phone  11  is able to connect to the Internet N through the gateway  12 .  
         [0031]    The cellular phone  11  that is able to make the access to the Internet N is connected to a server  13  on the Internet N via the radiocommunication. The server  13  has at least such functions as, for example, an event guide service  16 , a map data supply service  17 , and a printer server  18 .  
         [0032]    Further, the image forming system of the embodiment of the present invention has a terminal printer  14  that is installed in such places as stores, etc. that have a communication function to make the access to the Internet N and a money receiver  15  that is connected to the terminal printer  14  and urges a user to put a prescribed charge into it.  
         [0033]    The cellular phone  11  described above has a control function by a built-in microcomputer system (not shown). Under the control of this control function, radio waves given from an antenna terminal are received, demodulated by a demodulator (not shown), converted into voice signal and image data, and the voice signal is reproduced through a speaker and image data are displayed on a display. At the same time, under the control of this control function, operation signals corresponding to the operation buttons such as numerical figures, etc. and voice signals obtained through a microphone are modulated by a modulator and output through the antenna terminal as radio wave in prescribed frequency. Further, the operating procedures that are a special feature of the present invention explained in a flowchart shown later are stored in a memory as a processing program of the control functions described above.  
         [0034]    Further, the gateway  12  of a communication carrier is also a computer system that is controlled by the control function defined by a processing program. In addition, the server  13  to provide map data supply service provided on the above-mentioned Internet N is also a computer system given with a communication function controlled by the control function defined by a processing program. Here, the server  13  has, for example, data structures  21 ˜ 27  in the server as shown in FIG. 5.  
         [0035]    The above-mentioned terminal printer  14  provided in such stores as convenience stores is an image forming apparatus that is connected to the Internet N through a telephone line and has a communicating function, though its structural details are omitted. This image forming apparatus is composed of, for example, an interface (not shown) that has a communicating function, an image creating unit for creating prescribed image data from given image data, a printer engine unit for forming an image corresponding to image data on a recording medium such as copy paper, etc., and a control unit that has a memory area to store a control program for specifying process actions including operating process peculiar to the present invention that is specified in a flowchart described later.  
         [0036]    Further, when installed in such stores as convenience stores, etc., this image forming apparatus is installed by detecting latitude and longitude data by the GPS (Global Positioning system) on the setting screen (S 26  and S 27 ) shown in FIG. 4. Thus, when requesting the print, it is possible to provide position data that becomes the start point of map data to a print server.  
         [0037]    Further, the money receiver  15  has the interface (not shown) that is connected to the terminal printer  14  and transmits/receive control data. Under the control of the controller that has a memory area to store a control program for specifying process actions including operating process that is peculiar to the present invention specified in a flowchart described later, the money put into the money receiver by a user is detected according to the indication on the display urging a user to put a charge, the money is stored and a change is output properly.  
         [0038]    The image forming system of the embodiment of the present invention executes the process operations explained below with flowcharts using the units described above. A destination is input from the cellular phone  11  and reserves it in the print server. Thereafter, by operating the terminal printer  14 , the destination is taken out from the print server and a road guide print to the destination from the place of the terminal printer  14  installed is out put based on the latest data.  
         [0039]    &lt;Operation of Image Forming System&gt; 
         [0040]    The characteristic process operations of the image forming system described above will be explained in detail using the flowcharts. FIG. 7 is a flowchart showing the operations from the set-up to the map image output of the image forming system of the embodiment of the present invention, FIG. 8 is a flowchart showing the charge collection process by the money receiver, FIG. 9 is a flowchart showing the charge requesting process, FIG. 10 is a flowchart when providing and printing an additional service based on a time of the image forming system of the embodiment of the present invention, and FIG. 11 is a flowchart when executing the warning process for the time elapse of the print server.  
         [0041]    The image forming system of the embodiment of the present invention makes it possible to separate the operations for the cellular phone  11  and the terminal printer as shown below in the flowchart shown in FIG. 7. That is, when the cellular phone  11  is first started and then, connected to the Internet N through the gateway  12  by a communication carrier and accessed to the server  13  that provides a map data supply service, a display shown by S 11  in FIG. 2A appears and when the underline portion is clicked, a destination is input (S 31 ).  
         [0042]    Further, when the event guide site is accessed here as shown in FIG. 2B, it is possible to input a destination data by inputting a phone number or a residence or by specifying a male with a destination other than a latitude and longitude as a destination data.  
         [0043]    Thus, in the map data supply service  17 , destination candidates are searched (S 41 ), a table of candidates is prepared (S 42 ) and a moving method is selected by deciding a destination (S 32 ). Corresponding to this, in the map data supply service  17 , a destination is searched(S 43 ) and a table of additional services is prepared (S 44 ). When a user selects an additional service (S 33 ), in the printer server  18 , data including a destination are saved in a memory area temporarily (S 51 ). As a result of this saving process, the operation from the terminal printer  14  becomes possible later.  
         [0044]    Thereafter, in the printer server  18 , a user ID is inquired (S 52 ) and a user is urged to input of the user ID by the cellular phone as shown in the operation screen S 14  in FIG. 2 (S 34 ). When a user ID is input, it is saved in a data base shown by the user ID in the printer server  18  (S 53 ). According to this, a completion message is displayed as shown in Step S 15  in FIG. 2 (S 35 ). Further, when this user ID and a password are once input, the input of them can be omitted from the next access.  
         [0045]    Further, when the printer server  18  is accessed through the terminal printer  14  provided in a convenience store, etc. and a user ID is input (S 61 ), the terminal printer  14  displays a table of services and makes the selection (S 62 ) after acquiring the destination data saved corresponding to the user ID (S 54 ). Corresponding to this selection, a current position and a current time that are set by the GPS, etc. are acquired in the terminal printer (S 63 ). The map data supply service  17  prepares guide data from a point of departure, a destination, a moving method, etc. (S 45 ). Thereafter, when a selected additional service data is prepared, this data is supplied (S 46 ) and in the terminal printer  14 , print data are prepared from a guide map and additional service data (S 64 ), guide map, etc. are formed on a copy paper by the printer  14  and output (S 65 ).  
         [0046]    As described above, when various data including destination data of map such as a destination ID, etc. shown in FIG. 6 are set by the cellular phone  11  and stored in a memory area by the printer server  18 , the terminal printer  14  requests map data of a place of the terminal printer  14  as a starting point and a user input destination as a terminal point to the map data supply service site through the Internet N. The map data supply service site prepares guide data added with latest data at this time and returns the data to the terminal printer  14 . The terminal printer  14  receives this data, prints the data and provides it to a user. Thus, the present invention provides an image forming system that is able to make an operating environment convenient for user by executing complicated operation to specify map data, etc. by a cellular phone using a sufficient time according to convenience of user and the operation of the terminal printer  14  in a store where it tends to come confuse very easily.  
         [0047]    Next, the operations including setting, requesting and adjustment of charges accompanied with services of map data, etc. provided will be explained using a flowchart as shown in FIG. 8.  
         [0048]    In FIG. 8, when guide data and additional service data are prepared by the map data supply service  17  (S 71 ), a service charge and the number of prints are computed (S 72 ). Corresponding to this, the print server  18  computes a charge (S 81 ) and a print charge is computed from the number of printed sheets in the terminal printer  14  (S 91 ). Then, these charges are displayed to a user (S 92 ). The money receiver  15  detects the putting of money into the slot (S 101  and S 93 ), the map data supply service  17  transfers guide data and additional service data (S 73 ) and the printer server  18  adds an advertisement, etc. (S 82 ). Further, when the terminal printer  14  detects the input of money ( 93 ), the money receiver  15  locks the slot (S 102 ) and makes the accurate calculation (S 103 ).  
         [0049]    On the other hand, in the terminal printer  14 , print data is prepared from guide map and additional service data (S 94 ), the guide map is output to the printer (S 95 ) and further, it is reported (S 96 ) and the printer server executes the totalization process (S 83 ).  
         [0050]    Further, in the image forming system of the embodiment of the present invention, a charge can be requested as the fee for a telephone call not limiting to the money receiver  15  only. That is, when there is no approved advertisement, a charge for advertisement is made zero (S 118 ) and when there is an advertisement (S 111 ), an amount of a fee for printing the advertisement (S 112 ) and an amount to be claimed is decided by deducting a fee for advertisement (S 113 ). Then, when a destination ID and a password are confirmed (S 114 ), an amount claimed is charged to a destination ID in a sense of charging a sponsor of the server (S 119 ).  
         [0051]    However, when this charge cannot be claimed (S 114 ), if a charge was already paid through a cellular phone  11 , a charge is made payable through a cellular phone  11  (S 117 ). However, if not paid through a cellular phone  11 , a control data is supplied to the money receiver in order to collect a charge through the money receiver (S 116 ).  
         [0052]    Next, a service relative to a time schedule, etc. that are attached to a map data will be explained below. When a point of departure and a time of departure, a time of arrival are selected in the terminal printer  14  (S 125 ), the map data supply service  17  prepares a guide data from the point of departure, a destination, a moving method and a time of departure (S 121 ). Thereafter, if a time schedule was selected as an additional service (S 122 ), a time schedule is added to the guide data according to the point of departure, a time of departure and a time of arrival that supplied from the terminal printer  14  (S 123 ). Further, the selected additional service is prepared and provided to the terminal printer  14  (S 124 ).  
         [0053]    In the terminal printer  14 , this additional service data is received, print data is prepared from a guide map and additional service data (S 126 ), and the guide map with a time schedule, etc. attached are printed and output (S 127 ).  
         [0054]    Here, there is a method to make this time of departure to a time when a signal was sent from the terminal printer  14  or it may be made to a time after a prescribed time elapsed from this time. Further, it may be a time elapsed by a time definitely given from a user like 2 hours later, etc.  
         [0055]    Lastly, as indicated in the flowchart shown in FIG. 11, it is preferred to warn that various data that are set by a user of the cellular phone  11  are deleted with the elapse of a prescribed time. That is, in the printer server  18 , it is judged whether the alarm time is passed over (S 132 ) for all destinations (S 131 ) currently and if passed over, a signal allowing the deletion is sent to the cellular phone (S 133 ). Then, a certain time is added to the alarm time (S 135 ) and after waiting for N min. by repeating this, returned to the first Step S (S 136 ,  137 ).  
         [0056]    In the cellular phone  11 , when a mail is received (S 141 ), the mail is displayed (S 142 ). When a user clicks the URL of this mail (S 143 ), a home page is accessed to for deletion (S 144 ).  
         [0057]    On the deleting home page, a user of the cellular phone  11  is inquired for the deletion and exchanging a control signal between the cellular phone  11  and the deletion home page. When the deletion is directed (S 146 ), the alarm is deleted (S 149 ) and if not, a next alarm time is input (S 147 ) and the alarm time is updated (S 148  and S 151 ).  
         [0058]    Thus, when a certain time passed, stored data including destination data, etc. are deleted and therefore, the memory area can be secured.  
         [0059]    According to the image forming system of the present invention as described above, when destination data, etc. are received from a portable terminal, required data are not specified immediately but they are once stored in a storage area. Then, a user operates the terminal printer  14  and supplies, prints and outputs required image based on this stored data and terminal printer data. Thus, this invention is able to provide an image forming system that is capable of executing complicated operation to specify map data, etc. in a sufficient time for convenience of a user through a cellular phone and the operation through a terminal printer very simply in a store wherein it tends to become confuse and thus, the operating environment is made convenient for user.
