Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a document management system, a document processing device, a document processing control method thereof, and a program for executing the document processing control method. More particularly, the present invention relates to the document management system and the document processing device which execute a document process by using document process history information, and the document processing control method thereof. 
   2. Related Background Art 
   In recent years, as document data have been digitized widely, a document management system which consists of a document management server for managing the document data, and various client devices such as a PC (personal computer), a printer and the like has come to be used. Thus, a user can access the document management server from the client device such as the PC, the printer or the like, and, by using the client device, execute document processes such as document registration, document acquirement, document update, document print and the like with respect to the document management server. 
   On the other hand, as the conventional art, the printer which comprises the storage unit for storing, every time a print job is executed, history information of the print job and PDL (page-description language) data corresponding to the relevant history information is disclosed (for example, Japanese Patent Application Laid-Open No. 2003-330638). In this printer, if a user indicates the print job by selecting one of the history information stored in the storage unit, the PDL data corresponding to the selected history information is read, whereby the read PDL data can be reprinted. 
   Therefore, if the relevant printer is applied to the client device in the document management system, it is thought that a trouble that a user specifies desired data from among a huge amount of document data managed by the document management server and then designates the specified desired data as print data can be reduced. 
   However, the relevant printer comprising the storage unit for storing the history information is merely to simplify the reprint process to be executed in response to the operation by an individual user. In other words, the relevant printer is merely corresponding to a local environment. For this reason, even where the relevant printer is directly applied to the client device, when one user (called a user  1 ) executes the print process with respect to the document data that the user  1  wishes to conceal from another user (called a user  2 ), there is a problem that the user  2  can acquire the printed matter corresponding to the relevant document data on the basis of the history information and thus the contents of the relevant document data leak. 
   The above problem can be solved by enabling only the user  1  who indicated the print process to actually execute the print process based on the history information. However, even in that case, there is a problem that, if the user  1  executes the print process for, e.g., shared document data, the user  2  cannot reprint the relevant shared document data based on the history information. 
   Further, since the above conventional art discloses the method by which the document data subjected to the print process in the past is used for the reprint process, even where a document process other than the print process was executed in the past, the document data concerning the relevant document process cannot be used for the reprint process. 
   SUMMARY OF THE INVENTION 
   An object of the present invention is to provide a document processing device which can, in a case where a user wishes to execute, by designating desired document data, a document process based on the designated document data, reduce a trouble of specifying the desired document data from among a huge amount of document data and conceal the data to which the user does not have an access right, a document processing method which is applicable to the document management system and the document processing device, and a program which is used to execute the document processing method. 
   To achieve the above object, according to one aspect of the present invention, there is provided a document processing device comprises, an authentication unit adapted to authenticate the user, a history information storage unit adapted to store history information indicating that document data was processed after the document data was stored in a document management server, the history information including identification information for identifying the document data was processed after the document data was stored in a document management server, a user access right judgment unit adapted to judge whether or not the authenticated user has an access right to each document data corresponding to the identification information included in the history information, a display unit adapted to display information for enable a user to select the document data to which the authenticated user has the access right from among the document data corresponding to the identification information included in the history information, and a processing unit adapted to process to the document data selected by the user.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Hereinafter, the preferable embodiment of the present invention will be explained in detail with reference to the accompanying drawings. 
     FIG. 1  is a block diagram schematically showing the constitution of the document management system according to the embodiment of the present invention. 
   In  FIG. 1 , a document management system  1  consists of a print device  110 , a PC  140  and a document management server  120 . Here, the print device  110  acts as the client device which is operated by a user to execute a communication process for exchanging data through a network  130 . Further, a general network such as a LAN (local area network), the Internet or the like is used as the network  130 . Also, a physical cable such as a USB (Universal Serial Bus) or the like may be used as the network  130 . 
   The print device  110  consists of a scan execution unit  116  for reading an original, a print execution unit (document processing means)  115  for executing a print process, an information display unit (display means)  114  for showing information to the user and also accepting requests from the user, an information processing unit  113  for generating the information to be shown to the user by the information display unit  114  and also analyzing the request accepted from the user, a communication unit  112  for executing communication with the document management server  120  through the network  130 , and a history information management unit (history information storage means)  111  for managing the history information of the operations executed in the print device  110 . 
   The document management server  120  consists of a communication unit  124  for executing a communication process with the print device  110  through the network  130 , a processing unit  125  for receiving an access right request and a document acquirement request later explained with reference to  FIG. 4  from the print device  110 , analyzing the contents of these requests and executing the process according to the analyzed request in the document management server  120 , a DB unit  126  for storing document information  121 , access right information  122  and user information  123  later explained with reference to  FIGS. 2A to 2C , and a conversion unit  127  for converting the managed document data into the data capable of being printed by the print device  110 . 
   Incidentally, it is explained in  FIG. 1  that the document management server  120  and the print device  110  are independent from each other. However, the document management server  120  and the print device  110  may be provided integrally. In such a case, one document processing device will consist of the history information management unit  111 , the information processing unit  113 , the information display unit  114 , the print execution unit  115 , the scan execution unit  116 , the processing unit  125 , the conversion unit  127  and the DB unit  126 . 
     FIGS. 2A ,  2 B and  2 C are diagrams showing the information to be managed in the DB unit  126  of the document management server  120  shown in  FIG. 1 . 
   As shown in  FIGS. 2A to 2C , the DB unit  126  stores the document information  121 , the access right information  122  and the user information  123 . 
   The document information  121  is the information concerning the document data to be managed by the document management server  120 . More specifically, the document information  121  is the information for managing the document ID information representing a unique value with respect to a document, the document name representing the name of the document data, and the storage location information representing the location where the document data is stored, in the mutually associated state. Incidentally, although only the document ID information, the document name and the storage location information are shown by way of example in the present embodiment, but the present invention is not limited to them. That is, another information concerning the document may be managed in association with the document ID information, the document name and the storage location information. 
   The access right information  122  is the information representing presence/absence of the user&#39;s access right for the document data managed by the document management server  120 . More specifically, the access right information  122  is the information for managing the user ID information, the document ID information and the access right information “Read (reading)/Write (generating and changing)/Delete (deleting)/Nothing (no access right)” in the mutually associated state. 
   The user information  123  is the information representing the user who can use the document management system  1 . More specifically, the user information  123  is the information for managing the user ID information representing a unique value with respect to the user, the user name information representing a name of the user, and the login ID information representing a login ID of the user, and the password information representing a password of the user, in the mutually associated state. 
   Hereinafter, a case where, after a user A printed a document  1  and a document  2  by the print device  110 , a user B prints the document  1  by using the history information of the print operation by the user A will be explained with reference to  FIGS. 3 and 4 . 
     FIG. 3  is the diagram for explaining a history information storage process which is executed by the document management system  1 . 
   In  FIG. 3 , the print device  110  first displays the document processing menu on the information display unit  114 . Then, in a case where the user A selects the print process from the displayed document processing menu, the print device  110  displays a login screen  500  ( FIG. 5 ) on the information display unit  114  to request the user A to input the login ID and the password. 
   If the login ID and the password are input by the user A, the print device  110  transmits a login request consisting of the input login ID and the input password to the document management server  120  through the communication unit  112 . 
   Then, if the login request from the print device  110  is received through the communication unit  124 , the document management server  120  causes the processing unit  125  to check the user information managed in the user information  123  with the login ID and the password both included in the received login request. If the check by the document management server  120  succeeds, then the document management server  120  notifies the print device  110  through the communication unit  124  that the user A has been logged in. 
   Subsequently, if the notification that the user A has been logged in is received from the document management server  120 , the print device  110  displays a document operation screen  800  shown in  FIG. 8 . After then, if the request (server document request) to designate the print document from the document data of the document information  121  managed by the document management server  120  is issued from the user A on the document operation screen  800  (step S 301 ), the print device  110  requests the document management server  120  to transmit the list including the server documents (step S 302 ). More specifically, if a “DESIGNATE FROM LIST” button  801  shown in  FIG. 8  is selected by the user, the print device  110  detects that the document designation from the list is requested. 
   If the server document list request is received, the document management server  120  generates the data representing the list of the document data capable of being accessed by the logged-in user A, by using the access right information  122  and the document information  121 . Then, the document management server  120  transmits the generated data to the print device  110  as a server document list. 
   If the print device  110  acquires the server document list form the document management server  120  (step S 303 ), the acquired server document list is converted into the data (that is, a folder tree  802  and a list screen  803 ) capable of being displayed by the information display unit  114 , and the document in the converted data is shown by using the information display unit  114  so as to be selectable by the user (step S 304 ). Then, if the documents (that is, the document  1  and the document  2  in the present embodiment) are designated in the shown list by the user A (step S 305 ), the print device  110  requests the document management server  120  to acquire the document  1  and the document  2  through the communication unit  112  (step S 306 ). More specifically, if a “DECIDE” button  804  shown in  FIG. 8  is selected by the user, the print device  110  detects that the document acquisition request is issued. 
   If the document acquisition request is received from the print device  110 , the document management server  120  acquires the document  1  and the document  2  in the document information  121 . Then, the acquired information is converted by the conversion unit  127  into the data capable of being printed, and the converted data is then transmitted to the print device  110 . 
   If the data representing the documents  1  and  2  capable of being printed is acquires from the document management server  120  (step S 307 ), the print device  110  displays the print format setting screen. Then, the received data is printed by the print execution unit  115  in the document print format selected by the user based on the displayed contents (step S 308 ). If the print ends, as shown in  FIG. 9A , the print device  110  registers the information concerning the printed document data and the date and time when the print was executed (that is, the document ID information and the operation date and time information managed by the document management server  120 ) to the history information management unit  111  as the history information (step S 309 ). 
   In the explanation of  FIG. 3 , the print device  110  prints the document data selected by the user A. However, the present invention is not limited to this. That is, it is possible to attach the document data selected by the user A to an electronic mail and then transmit the relevant electronic mail to a predetermined electronic mail address, and it is also possible to transmit the document data selected by the user A through facsimile. 
     FIG. 4  is the diagram for explaining a reprint process which is executed by the document management system  1 . 
   In  FIG. 4 , in the first instance, the print device  110  executes the process same as the login process for the user A shown in  FIG. 3 , whereby a user B is logged in. Thus, the document operation screen  800  as shown in  FIG. 10  is displayed on the information display unit  114 . Then, when a request (history information request) to designate the print document from the list of the recently used documents is input by the user B on the document operation screen  800  through the print device  110  (YES in step S 401 ), the process advances to a step S 402 . Here, if a “DESIGNATE FROM RECENTLY USED DOCUMENTS” button  1002  shown in  FIG. 8  is selected by the user, the print device  110  detects that the history information is requested. Incidentally, in the present embodiment, it is assumed that only the print operation histories of the documents  1  and  2  by the user A exist in the history information. 
   In the step S 402 , the print device  110  requests the access right information to the document management server  120 . Here, it should be noted that the access right information represents, from among the document data corresponding to the document ID included in the history information, to which document data the user B has the access right. After then, the access right information generated by the document management server  120  is acquired in response to such a request (step S 403 ), and the list of the documents to which the user B has the access right is generated based on the acquired access right information. Incidentally, the process from the step S 402  to the document list generation will be explained in detail with respect to a later-described document list generation process shown in  FIG. 6 . 
   Next, the print device  110  causes the information display unit  114  to show the list (a list screen  1001  shown in  FIG. 10 ) of the documents capable of being reprinted, based on the generated history information (step S 404 ). Here, it should be noted that the documents on the list screen  1001  are displayed so as to be selectable by the user, and only the document  1  is displayed on the list screen  1001  in the present embodiment. 
   If one of the documents included in the shown list (that is, the document  1  in the present embodiment) is designated by the user B (step S 405 ), the print device  110  requests, through the communication unit  112 , the document management server  120  to acquire the document  1  by using the document ID (step S 406 ). More specifically, if the “DECIDE” button  804  shown in  FIG. 10  is selected by the user, the print device  110  detects that the document acquisition request is issued. 
   If the document acquisition request from the print device  110  is received by the document management server  120 , the document data of the document  1  in the document information  121  is acquired by the processing unit  125 . Then, the acquired information is converted by the conversion unit  127  into the data capable of being printed, and the converted data is then transmitted to the print device  110 . 
   If the data representing the document  1  capable of being printed is acquires from the document management server  120  (step S 407 ), the print device  110  displays the print format setting screen. Then, the received data is printed by the print execution unit  115  in the document print format selected by the user based on the displayed contents (step S 408 ). 
   According to the processes shown in  FIGS. 3 and 4 , in the case where the history information is requested from the user B (step S 401 ) after the history information was registered in the processes as shown in  FIG. 3 , the print device  110  acquires the access right information from the document management server  120  (steps S 402  and S 403 ). Then, the list of the document data, to which the user B has the access right, from among the document data (document  1  and document  2 ) corresponding to the identification information included in the history information is generated based on the acquired access right information, and the generated list is shown to the user (step S 404 ). Subsequently, when the user B designates the document  1  from the shown list (step S 405 ), the print data of the document  1  is acquired from the document management server  120  (steps S 406  and S 407 ), and the acquired print data is actually printed (step S 408 ). Thus, even if the document management server  120  has to manage a huge amount of document data when the user B executes the print process by using the print device  110 , it is possible to reduce a trouble of designating as the print data one document data from among the huge amount of document data. 
   Further, the print device  110  does not display on the list screen  1001  the document  2  to which the user B does not have the access right. Thus, it is possible to conceal, from among the document data to be managed by the document management server  120 , the document data (the document  2 ) to which the user B does not have the access right. As a result, since it is possible to inhibit the user B from indicating the print of the document  2 , it is possible to increase security and it is also possible to prevent occurrence of operation errors. 
   Moreover, if the print ends in the step S 408 , as shown in  FIG. 9B , the operation date and time information of the print operation history information for the document  1  managed by the history information management unit  111  is updated from the information representing the date and time when the print process is executed by the user A to the information representing the date and time when the reprint process is executed by the user B. After the information was updated, the list of the documents capable of being subjected to the reprint process based on the history information is updated. Thus, the user can always execute the print process based on the latest history information. 
   Furthermore, when the list is shown to the user B in the step S 404 , it is possible to simultaneously display the name of the document data to which the document process was executed in the past, the storage destination of the relevant document data in the document management server  120 , and the date and time information representing the date and time when the relevant document process was executed. Thus, it is possible to grasp or comprehend all at once the contents of the document data that the authenticated user can designate as the print data. 
   Moreover, in the present embodiment, since the access right settings that the plural client devices including the print device  110  request to change are updated in a lump by the document management server  120 , it is possible to instantly reflect such update in the print process based on the history information, whereby it is possible to easily mange the whole system. 
   In the explanation of  FIG. 4 , the document data selected by the user B is printed by the print device  110 . However, the present invention is not limited to this. That is, it is possible to attach the document data selected by the user B to an electronic mail and then transmit the relevant electronic mail to a predetermined electronic mail address, and it is also possible to transmit the document data selected by the user through facsimile. 
     FIG. 6  is a flow chart showing the procedure of the document list generation process to be executed by the print device  110  shown in  FIG. 1 . 
   In  FIG. 6 , it is first judged whether or not the history information exists in the history information management unit  111  (step S 601 ). Then, if it is judged that the history information exists in the history information management unit  111 , it requests, to the document management server  120  through the communication unit  112 , the acquisition of the access right information of the user B for the history information of all the documents executed in the past with respect to the document management server  120  (step S 602 ). At that time, all the document ID&#39;s and the user ID of the user B stored as the history information are simultaneously transmitted to the document management server  120 . 
   If the request of the acquisition of the access right information is received through the communication unit  124 , the document management server  120  executes a later-described access right information transmission process shown in  FIG. 7  to transmit the access right information including the document ID of the document to which the user B has the access right to the print device  110  (step S 603 ). 
   If the access right information is received from the document management server  120 , it is judged by the print device  110  whether or not the check of presence/absence of the access right of the user B to the history information of all the document executed for the document management server  120  in the past ends (step S 604 ). More specifically, if the comparison of the access right information received from the document management server  120  with all the document ID&#39;s of the documents included in the history information ends, it is judged that the check ends. 
   If it is judged in the step S 604  that the check does not end, it is further judged whether or not the user B has the access right to the document to which the check does not end (step S 605 ). More specifically, if the document ID of the document to which the check is currently executed is included in the access right information received from the document management server  120 , it is judged that the user B has the access right to the relevant document. Meanwhile, if the document ID is not included in the access right information, it is judged that the user B does not have the access right to the relevant document. 
   Then, after the step S 605 , the document name and the storage location information are directly added to the document to which the user B does not have the access right, or the document name and the storage location information are added to the document list of the document to which the user B has the access right (step S 606 ). Subsequently, the processes in the step S 604  and the subsequent steps are repeated. 
   If it is judged in the step S 604  that the check ends, the document list is sorted with the designated item (step S 607 ), and the document list generation process ends. 
     FIG. 7  is a flow chart showing the procedure of the access right information transmission process in the step S 603  shown in  FIG. 6 . 
   Here, it should be noted that the access right information transmission process is executed by the document management server  120 . 
   In  FIG. 7 , if the request of the step S 602  to acquire the access right information of the user B is received from the print device  110  by the processing unit  125  (YES in a step S 701 ), it is then judged whether or not the check of presence/absence of the access right of the user B to all the documents ends (step S 702 ). More specifically, if the comparison of the access right information  122  with all the documents of the document ID transmitted from the print device  110  when the request of the step S 602  is issued ends, it is judged that the check ends. In the present embodiment, since the history information includes only the histories of the print operations of the document  1  and the document  2 , it is judged in the step S 702  whether or not the check of presence/absence of the access right to the document  1  and the document  2  ends. 
   If it is judged in the step S 702  that the check does not end, the information representing whether or not the user B has the access right to the document to which the check does not end is acquired (step S 703 ), and the processes in the step S 702  and the subsequent steps are repeated. In the acquisition process, if the user ID of the user B is included in the user ID of the document in the access right information  122 , it is judged that the user B has the access right. Meanwhile, if the user ID of the user B is not included in the user ID of the document in the access right information  122 , it is judged that the user B does not have the access right. 
   Then, when the check ends in the step S 702 , the document ID and the storage destination information thereof are acquired with respect to the document to which the information to which the user B has the access right is acquired in the step S 703 , and the access right information including the acquired various information data is generated (step S 704 ). In the present embodiment, since it is set that the user B has the access right only to the document  1 , the document management server  120  generates the access right information including the document ID of the document  1  and the storage destination information thereof. 
   After then, the generated access right information is transmitted from the communication unit  124  to the print device  110  (step S 705 ), and the access right information transmission process ends. 
   According to the processes shown in  FIGS. 6 and 7 , as well as the access right request, the print device  110  transmits the document ID and the user ID of the user A included in the history information to the document management server  120  (step S 602 ), and, through the access right information transmission process, the print device  110  receives the access right information including the document ID from the document management server  120  (step S 603 ). In this instance, it is judged that the user B has the access right to the document data of the relevant document ID (YES in step S 605 ). On the other hand, as well as the reception of the access right request from the print device  110  in the step S 602 , the document management server  120  receives the document ID (step S 701 ). Then, in the document management server  120 , the access right information including the document ID of the document data that the access right is set to the transmitted user ID based on the access right information  122  included in the received document ID is generated (step S 704 ), and the generated access right information is transmitted to the print device  110  (step S 705 ). Thus, it is possible on the side of the print device  110  to surely judge to which of the document data corresponding to the document ID included in the history information the user B has the access right. Further, if there is the document to which the user B has the access right from among the documents included in the history information (YES in step S 605 ), the document name of the relevant document and the information of the storage location of the relevant document are added to the document list of the documents capable of being reprinted (step S 606 ). Thus, it is possible to surely conceal from the user B the document data that the user A does not wish to make the user B to know the contents. 
     FIG. 8  is the diagram showing the document operation screen to be displayed in the step S 304  of  FIG. 3 . 
   More specifically, the screen shown in  FIG. 8  is the screen which is displayed in the step S 304  after the server document is requested by the user in the step S 301  by selecting the “DESIGNATE FROM LIST” button  801  on the document operation screen  800  with the user. 
   On the screen shown in  FIG. 8 , if a folder  805  in which the desired document data have been held is selected by the user in a leftward folder tree  802 , the list of the document data held in the selected folder  805  is displayed on a center list screen  803 . Then, the user A selects the document corresponding to the desired data (document  1  and document  2 ) from the document data list displayed on the list screen  803 . 
   For example, if the folder which contains the data desired by the user A exists on the tenth layer (hierarchy), it is necessary to open the relevant layer by selecting the folders of the folder tree  802  ten times. Further, since the number of document data capable of being displayed on the list screen  803  at a time is limited, if a large number of document data are held in one folder, it is necessary to browse the document data in the relevant folder by scrolling them. Furthermore, if the user does not correctly know or grasp in which folder the desired data has been stored, the user A has to search various folders displayed in the folder tree  802 . In such a case, the user A has to open the layers by selecting ten or more folders. 
     FIG. 10  is a diagram showing the document operation screen which is displayed in the step S 404  of  FIG. 4 . 
   More specifically, the screen shown in  FIG. 10  is the screen to be displayed in the process of the step S 404  after the user requests the history information in the step S 401  of  FIG. 4  by selecting the “DESIGNATE FROM RECENTLY USED DOCUMENTS” button  1002  on the document operation screen  800 . 
   On the center list screen  1001  shown in  FIG. 10 , the document list generated based on the access right information and the history information is displayed. 
   Consequently, even if the user B does not operate or handle the folder tree  802  and the list screen  803  ( FIG. 8 ), the names of the desired documents are displayed on the list screen, the user B can easily execute the document selection. 
   Typically, the user interface of the device such as the print device  110  is smaller in size than that of the PC, whereby it is difficult for the user to operate or handle it. For this reason, if it is possible to decrease the user&#39;s operations even by one, it is possible to make the user interface significantly easy-usable for the user. 
   Next, a case where, after the user A scanned the documents  1  and  2  by the print device  110 , the user B prints the document  1  by using the history information of the scan operation will be explained with reference to  FIG. 11 . 
     FIG. 11  is the diagram for explaining a modification of the history information storage process to be executed by the document management system  1  shown in  FIG. 1 . 
   In  FIG. 11 , the print device  110  first displays the document processing menu on the information display unit  114 . Then, if a user C scans new document data in the displayed document processing menu to request the process to be registered to the document management server  120  (scan registration request) (step S 1101 ), the process same as the login process to the user A shown in  FIG. 3  is executed. Subsequently, if the user C is logged for the document management sever  120 , a document operation screen  1200  as shown in  FIG. 12  is displayed on the information display unit  114 . 
   After then, the storage destination folder (“FIRST BUSINESS SECTION” folder) in a folder tree  1201  disposed at the left on the document operation screen  1200  is selected by the user, the document name (“DOCUMENT 1”) of the new document acquired by the scan is input by the user to a registration file name description section  1202 , and the “DECIDE” button is then depressed by the user. Thus, the print device  110  scans a paper original set on the scan execution unit  116  (step S 1102 ), converts the scanned data into the electronic data by the information processing unit  113 , and then transmits the scanned electronic data, the document name and the storage folder information from the communication unit  112  to the document management server  120  (step S 1103 ). 
   Subsequently, the document management server  120  registers the received electronic data to the document information  121  as the folder destination and the document name both designated by the user on the document operation screen  1200 . At this point, since the access right to the document  1  is given only to the user A, the information representing that the user A can access the document  1  is registered to the access right information  122 . Further, when the electronic data is registered to the document information  121 , the document ID information by which the registered document can be uniquely specified is generated and registered together. When the registration of document ends, the document management server  120  transmits the registration end notification, and the information representing the registered document name and the document ID issued at the time of registration to the print device  110 . 
   If the registration end notification is received from the document management server  120 , the print device  110  registers the registered document ID and the date and time when the registration was executed to the history information management unit  111  as the history of registration (step S 1104 ). In addition, it should be noted that the document  2  is registered in the manner same as above. 
   After the above registration process ended, the user C accesses the document management server  120  from the PC  140  to set the access right to the registered documents  1  and  2  (step S 1105 ). 
   After then, a user D can print the document  1  based on the history information of the scan registration process shown in  FIG. 11 , by executing the process same as the reprint process in  FIG. 4  executed by the user B. 
     FIG. 3  is the diagram for explaining the history information storage process which is executed by the document management system  1 . 
   According to the processes shown in  FIG. 11 , after the history information is newly added and registered through the processes shown in  FIG. 4  (step S 1104 ), and if the access right of the newly registered document is set by the PC  140  to the document management server  120  (step S 1105 ), then the print device  110  can execute the print process same as that shown in  FIG. 4  on the basis of the operation or handling by the user D. Consequently, even if the scan registration process was executed in the print device  110  in the past, it is possible to execute the print process based on the history information thereof. 
   Likewise, after the shared document was registered from the print device  110 , if the access right to the shared document is set to all the users of the relevant system, it is possible for other users to easily execute the print by using the registered history information. 
   Incidentally, it should be noted that the print format setting information may be included in the information to be managed as the history information. In the history information storage process in this case, the print format information designated by the user in the step S 308  as shown in  FIG. 13  is included as the information to be stored as the history information in the step S 309  of  FIG. 3 . Further, in the reprint process to be executed thereafter, the print format setting screen is not displayed in the step S 408  of  FIG. 4 , and the document data designated by the user in the step S 405  is printed with the print format of the print format information included in the history information with respect to the relevant document data. 
   Thus, since the print format of the document data which was set in the past print process is set as the print format when the reprint process of the relevant document data is executed based on the history information, it is unnecessary for the user to set the print format in the reprint process, whereby it is possible to more simplify the user&#39;s operation. 
   Further, for example, in a case where the user who is skilled in setting the print device  110  once executed the print with the complicated print setting, it is then possible for another user who is not skilled in setting the print format to easily execute the reprint with the relevant complicated print setting based on the history information. 
   Furthermore, it can be obviously understood that the object of the present invention can be attained even in a case where a storage medium (or a recording medium) storing therein the program codes of software to achieve the functions of the above embodiment is supplied to a system or a device, and thus the computer (or CPU, MPU) in the system or the device reads and executes the program codes stored in the medium. 
   In this case, the program codes themselves read out of the storage medium achieve the functions of the above embodiment, whereby the storage medium storing these program codes constitutes the present invention. 
   Further, it can be obviously understood that the present invention includes not only the case where the functions of the above embodiment are achieved by executing the program codes read by the computer, but also the case where an OS (operating system) or the like running on the computer executes a part or all of the actual processes based the instructions of the program codes and thus the functions of the above embodiment are achieved by these processes. 
   Furthermore, it can be obviously understood that the present invention also includes a case where, after the program codes read out of the storage medium are written into the memory of a function expansion card inserted in the computer or the memory in a function expansion unit connected to the computer, the CPU or the like provided in the function expansion board or the function expansion unit executes a part or all of the actual processes based on the instructions of the program codes, and thus the functions of the above embodiment are achieved by these processes. 
   Moreover, because the form of such a program is no object if it has the actual function as the program to be achieved by the computer, an object code, a program executed by an interpreter, script data supplied to the OS, and the like may be included as the program. 
   As the storage medium for supplying the program, for example, a RAM, an NV-RAM, a Floppy™ disk, an optical disk, a magnetooptical disk, a CR-ROM, an MO, a CD-R, a CD-RW, a DVD (DVD-ROM, DVD-RAM, DVD-RW, DVD+RW), a magnetic tape, a nonvolatile memory card, another ROM, or the can be used, if the relevant medium can store the program. Alternatively, the relevant program is supplied by downloading it from a not-shown another computer, a database or the like connected to the Internet, a commercial network, a local area network or the like. 
   This application claims priority from Japanese Patent Application No. 2005-061333 filed Mar. 4, 2005, which is hereby incorporated by reference herein.
