Description

  The present invention relates to a document server, a printing method, and a program.

  2. Description of the Related Art Conventionally, a printing system has been known in which a document stored in a server provided on the Internet can be downloaded to a printing apparatus installed in an arbitrary convenience store and printed out ( For example, Patent Document 1). In this conventional printing system, for example, when a user operates a computer or the like to upload and register a document to the server, the server assigns and stores a unique document ID to the document. The document registered in the server in this way can be printed out by inputting the document ID and logging in to the server from a printing apparatus installed in a convenience store or the like.

  Documents registered on the server can be printed out not only by the uploading user who uploaded the document, but also when other users enter the document ID by operating the printing device at a convenience store on the go. And multiple users can share documents. For this reason, such a printing system is used, for example, to provide sales representatives with materials that require assistance from the office for sales representatives who frequently go out, or used during lectures by lecturers. It can be used to distribute materials to each student.

JP 2002-32205 A

  However, in the conventional printing system, in order for another user different from the uploading user to download the document stored in the server and print it out, the unique document ID assigned at the time of document registration is input every time. You need to log in to the server. Such a document ID is an ID that is unfamiliar to other users and is generally composed of a complex character string having a predetermined number of characters or more. Therefore, when inputting the document ID, there is a problem that an input error of the document ID is likely to occur and the operation is complicated.

  This problem becomes even more prominent particularly when a plurality of documents stored in the server are simultaneously downloaded and printed out. In other words, when a plurality of documents stored in the server are simultaneously downloaded and printed out, it is necessary to download them one by one while inputting the document ID assigned to each document each time. The operability is further deteriorated.

  On the other hand, if an account of another user who shares the document is registered in the server and the uploading user of the document knows the account information (for example, user ID) in advance, If the account information of other users who share the document is specified in advance, the above problem does not occur. That is, in this case, when another user downloads a document stored on the server and prints it out, he / she logs in to the server by inputting his / her own account information (for example, user ID and password) that he / she is familiar with. As a result, it is possible to print out a document that can be downloaded by itself, and there is no need to perform a complicated input operation of the document ID. However, this is based on the premise that the upload user knows the account information of other users in advance, otherwise the above-described problem still occurs. Therefore, if a user who does not want to share his / her account information with the uploading user uses the printing system to print out, the printing system is used to distribute the materials used by the speaker during the lecture to unspecified students. However, there is still a problem that the operability at the time of print output is poor.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments described below, members that are common to each other are denoted by the same reference numerals, and redundant descriptions thereof are omitted.

  FIG. 1 is a diagram illustrating a conceptual configuration of a printing system according to an embodiment of the present invention. This printing system includes a document server 1, a computer (information processing device) 2 used by a user X, and a plurality of printing devices 3a, 3b, 3c installed in convenience stores 5a, 5b, 5c, etc. Is connected to a network 4 such as the Internet. The document server 1 is a server configured with a computer provided on a cloud such as the Internet, for example, and provides a service related to management of documents received via the network 4 and print output of the documents. The document server 1 includes a storage device 14 composed of a hard disk device or the like in order to store various documents received via the network 4 and other various information. Each of the plurality of printing apparatuses 3 a, 3 b, 3 c is configured by, for example, an MFP (Multifunction Peripherals) and can perform an operation in cooperation with the document server 1 via the network 4. That is, the plurality of printing apparatuses 3a, 3b, and 3c can download a document stored in the document server 1 and print it out. In the following description, each of the plurality of printing apparatuses 3a, 3b, and 3c is generically referred to as a printing apparatus 3.

  In this printing system, a plurality of users can share and use a document registered and stored in the document server 1. For example, as shown in FIG. 1, when the user X operates the computer 2 and uploads the document 9 to the document server 1, the document server 1 stores the document 9 in the storage device 14 and registers it. At this time, when the user X designates that the user A is a shared user of the document 9, the document server 1 stores a document that can be shared and used by the user A with respect to the portable terminal 6 or the like possessed by the user A. Notify that registered. Upon receiving this notification, the user A moves to any one of the plurality of convenience stores 5a, 5b, 5c, and operates the printing apparatus 3 installed therein, and then the document 9 registered by the user X is converted into a document. It can be downloaded from the server 1 and printed out. In the following, first, basic operations in such a printing system will be described.

  FIG. 2 is a diagram showing a basic operation when the user X registers the document 9 in the document server 1. First, the user X operates the computer 2 to input his / her account information (for example, user ID and password) registered in the document server 1, and transmits the account information to the document server 1 (process P1). . When the account of the user X is not registered in the document server 1, the user X performs an operation for registering his / her account in the document server 1 prior to the process P1.

  When the document server 1 receives the account information input by the user X, the document server 1 performs login determination to determine whether the user X is a registered user based on the account information (process P2). If the user X is a registered user, the document server 1 permits the login of the user X and displays an operation screen for uploading or downloading a document on the display screen of the computer 2.

  If the login to the document server 1 is successful, the user X operates the computer 2 to select the upload target document 9 and instruct the upload, and the document 9 is transmitted from the computer 2 to the document server 1 ( Process P3). At this time, a plurality of documents 9 selected by the user X may be transmitted simultaneously.

  When the document server 1 receives the document 9 designated by the user X, the document server 1 saves and registers the received document 9 in the storage device 14 (process P4). Further, the document server 1 assigns unique identification information (for example, document ID and password) to the document 9 registered in the process P4, and manages the identification information in association with the document 9 (process P5). Thereafter, the document server 1 notifies the computer 2 that the registration process has been completed (process P6). At this point, the document 9 registered in the document server 1 can be used only by the user X who is the uploading user.

  On the other hand, when the user X shares the document 9 registered in the document server 1 with the user A as described above, when the user X further operates the computer 2 to input the email address of the user A as the destination information, the destination information Is transmitted from the computer 2 to the document server 1 (process P7).

  When the document server 1 receives the destination information input by the user X, the document server 1 performs user determination to determine whether or not the destination information matches the destination information of the registered user registered in the document server 1 in advance (process) P8). As a result, it is determined whether or not the user A who becomes the shared user of the document 9 is a registered user registered in the document server 1. Based on the result of the user determination, the document server 1 performs sharing settings so that the document 9 registered by the user X can be shared and printed by the user A who is a shared user (process P9). .

  In this sharing setting, the user A, who is a shared user of the document 9, is a registered user who is registered in the document server 1 and a user A who is an unregistered user who is not registered. The printing conditions for performing output are set to different conditions. That is, if the user A is a registered user, the user A can log out to the document server 1 by inputting his / her account information (for example, user ID and password), so that the document 9 shared by the user A can be printed out. The printing conditions are set in If the user A is an unregistered user, the user A inputs the identification information (for example, document ID and password) given at the time of registration of the document 9 and logs into the document server 1, whereby the document 9 shared by the user A is shared. The printing conditions are set so that can be printed out.

  When the document server 1 performs the sharing setting, the document server 1 notifies the user A who is a sharing user that the sharing setting of the document 9 has been performed by sending an e-mail EM1 (process P10). Again, different processing is performed depending on whether user A is a registered user or an unregistered user. It was described that when user A is a registered user, user A can log in to document server 1 with his / her account information to download document 9 set for sharing and print it out. An electronic mail EM1 is automatically generated and transmitted to the user A. On the other hand, when the user A is an unregistered user, the identification information given at the time of registration of the document 9 is described in the email EM1, and the sharing setting is performed by logging into the document server 1 with the identification information. An electronic mail EM1 describing that it is possible to download the printed document 9 and print it out is automatically generated and sent to the user A.

  The user A can grasp the printing conditions for printing out the document 9 set to be shared by receiving and checking such an electronic mail EM1 with his / her mobile terminal 6 or the like. Then, by moving to the nearest printing device 3 and operating the operation panel of the printing device 3, the document 9 set to be shared can be downloaded and printed out.

  FIG. 3 is a diagram illustrating an example of a display screen displayed on the operation panel of the printing apparatus 3. The printing apparatus 3 displays the initial screen G1 in the initial state. In this initial screen G1, a first login button B1 for each user to log in to the document server 1 with his / her account information, and a second for each user to log in with identification information given to the document 9 are displayed. A login button B2 is displayed. While the initial screen G1 is displayed, the user A operates one of the first and second login buttons B1 and B2 according to the notification content of the email EM1.

  When the user A operates the first login button B1, the printing apparatus 3 changes the initial screen G1 and displays the first login operation screen G2 as shown in FIG. On the first login operation screen G2, account information including a user ID and a password can be manually input. On the other hand, when the user A operates the second login button B2, the printing apparatus 3 makes a transition from the initial screen G1 to the second login operation screen G3 and displays it. On the second login operation screen G3, the document ID and password included in the identification information given to the document 9 can be manually input. Therefore, the user A transmits one of the account information and the identification information to the document server 1 by performing an input operation on one of the first and second login operation screens G2 and G3. be able to.

  FIG. 4 is a diagram showing a basic operation when user A inputs his / her account information and prints out a document. When the user A inputs his / her account information to the printing apparatus 3, the printing apparatus 3 transmits the account information to the document server 1 (process P20). When the document server 1 receives the account information, the document server 1 performs login determination to determine whether or not the user A is a registered user based on the account information (process P21). If the user A is a registered user, the document server 1 permits the user A to log in, and extracts all documents that the user A can print out (process P22). At this time, all the documents registered by the user X and set to be shared with the user A are extracted. However, not only documents registered by the user X but also documents (for example, non-shared documents) registered in advance by the user A themselves are extracted. Then, the document server 1 generates a list screen of documents 9 that can be printed out by the user A and displays it on the operation panel of the printing apparatus 3 (process P23). When the user A selects a document to be printed from the list screen, a print request specifying the document 9 to be downloaded is transmitted from the printing apparatus 3 to the document server 1 (process P24). .

  Upon receiving the print request, the document server 1 transmits the document 9 designated by the print request to the printing apparatus 3 (process P25). Thereby, the printing apparatus 3 can download and acquire the document 9 from the document server 1. The printing apparatus 3 prints out the document 9 downloaded and acquired from the document server 1 (process P26), and when the print output is completed, sends a completion notification to the document server 1 (process P27). Therefore, the user A who is a registered user of the document server 1 inputs his / her account information he / she is familiar with and performs the above procedure, so that the printed matter of the document 9 registered by the user X can be found at the nearest convenience store. It can be obtained at stores.

  Next, FIG. 5 is a diagram showing a basic operation when the user A inputs the identification information of the document 9 and prints out the shared document. When the user A inputs identification information to the printing apparatus 3, the printing apparatus 3 transmits the identification information to the document server 1 (process P30). When the document server 1 receives the identification information, the document server 1 performs identification information determination for determining whether or not the document 9 to which information corresponding to the identification information is registered is registered (process P31). If the document 9 matching the identification information input by the user A is registered, the document server 1 permits login with the identification information, and extracts a shared document that can be printed out with the identification information (process). P32). Then, the document server 1 generates a print screen of the extracted document 9 and displays it on the operation panel of the printing apparatus 3 (process P33). When the user A performs an operation on the print screen to instruct print output, the print apparatus 3 transmits a print request designating the document 9 to be downloaded to the document server 1 (process P34).

  Upon receiving the print request, the document server 1 transmits the document 9 designated by the print request to the printing apparatus 3 (process P35). Thereby, the printing apparatus 3 can download and acquire the document 9 from the document server 1. The printing apparatus 3 prints out the document 9 downloaded and acquired from the document server 1 (process P36), and when the print output is completed, sends a completion notification to the document server 1 (process P37). Therefore, the user A who is an unregistered user of the document server 1 inputs the identification information notified by the e-mail EM1 and performs the above procedure, so that the printed matter of the document 9 registered by the user X is the nearest. You can get it at a convenience store.

  Next, a specific configuration and operation of the document server 1 that realizes the basic operation as described above will be described in detail.

  FIG. 6 is a block diagram illustrating an example of a hardware configuration and a functional configuration of the document server 1. The document server 1 includes a network interface 10, a CPU 11, a RAM 12, an NVRAM 13, and a storage device 14 as a hardware configuration. The network interface 10 is for connecting the document server 1 to a network 4 such as the Internet and communicating with each of the computer 2 and the printing apparatus 3. The CPU 11 implements various functions as the document server 1 by executing a program 15 stored in advance in the NVRAM 13. The RAM 12 is a memory for storing temporary data generated when the CPU 11 executes the program 15. The NVRAM 13 is a non-volatile memory, and stores various data in addition to the program 15 executed by the CPU 11. As described above, the storage device 14 is a non-volatile storage unit configured by a hard disk device or the like.

  The storage device 14 includes an account information storage unit 16, a document storage unit 17, and a shared information storage unit 18. The account information storage unit 16 stores account information 27 of each user registered in the document server 1. The document storage unit 17 is a storage area for storing a document 9 received by the document server 1 via the network 4. Unique identification information 8 given at the time of document registration is added to the document 9 stored in the document storage unit 17. The shared information storage unit 18 is a storage area for storing shared information 28 defining the shared setting when the shared setting is performed for the document 9 registered in the document storage unit 17.

  FIG. 7 is a diagram illustrating an example of the account information 27 and the shared information 28. First, as shown in FIG. 7A, the account information 27 is information in which the user name, user ID, password, and e-mail address of the user registered in the document server 1 are recorded. Such account information 27 is information that can be freely set by each user when an account is registered in the document server 1, for example. However, the user ID and password are unique character strings for each user in the document server 1. Since the e-mail address is included in the account information 27, when an e-mail address is input as destination information for the shared user, whether the shared user is a registered user by referring to the account information 27 of all users. It can be determined whether or not.

  Further, as shown in FIG. 7B, the shared information 28 is information in which information related to all documents 9 for which sharing setting has been performed is recorded. In the example of FIG. 7B, information regarding four documents 9a, 9b, 9c, and 9d is recorded. The shared information 28 includes information that is recorded in association with each document 9a, 9b, 9c, and 9d for which sharing is set, identification information 8 that includes a document ID and a password, the file name of the document 9, and the document 9 Upload user registered by uploading, shared user sharing the document 9, output conditions when the shared user performs print output, and an integration ID given when a plurality of documents are integrated. .

  The document ID and password included in the identification information 8 have a predetermined number of characters or more and are configured with a unique character string in the document server 1 in order to increase the security level. The identification information 8 may be automatically generated randomly by the document server 1 or specified by the upload user. In the shared user item, the e-mail address (destination information) of the shared user input by the upload user is recorded. When a plurality of shared users are set for one document 9, the electronic mail addresses of the plurality of shared users are recorded. Also, in the output condition item, which account information or identification information is used as a condition for logging in when each shared user prints out the document 9 is recorded. In the example of FIG. 7B, “A” is recorded in the output condition when the login with account information is a condition, and “D” is output as the output condition when the login with identification information is a condition. Is recorded. In the integrated ID item, when a plurality of documents 9 can be integrated into one, the same ID is recorded for each of the plurality of documents 9. In the example of FIG. 7B, the documents 9a and 9d are set as documents that can be integrated into one. The integration of the document 9 will be described in detail later.

  Returning to FIG. 6, the CPU 11 functions as the login control unit 21, the registration processing unit 22, the output control unit 23, and the deletion processing unit 24 by reading and executing the program 15 stored in the NVRAM 13.

  The login control unit 21 is a processing unit that determines whether login is permitted based on account information or identification information received via the network interface 10. When the login control unit 21 receives account information, whether or not the account information 27 of each registered user recorded in the account information storage unit 16 includes information that matches the received account information. Determine. As a result, if the matching information is included, the registered user can be specified, so the login control unit 21 permits login with the account information. On the other hand, when the identification information is received, the login control unit 21 determines whether the shared information 28 stored in the shared information storage unit 18 includes information that matches the received identification information. judge. As a result, if matching information is included, the login control unit 21 permits login with the identification information. In the case of login with identification information, the document 9 can be specified, but the user who performed the access operation cannot be specified.

  The registration processing unit 22 functions after login is permitted based on account information transmitted from the computer 2, for example, and performs processing for registering the document 9 transmitted from the computer 2. The output control unit 23 functions after login is permitted based on, for example, account information or identification information transmitted from the printing apparatus 3, and is a processing unit that controls printing output in the printing apparatus 3.

  FIG. 8 is a diagram illustrating an example of detailed functional configurations of the registration processing unit 22 and the output control unit 23. First, as illustrated in FIG. 8A, the registration processing unit 22 functions as a registration unit 31, an identification information adding unit 32, a destination information input unit 33, a determination unit 34, a share setting unit 35, and a share notification unit 36. And they function in order. The registration unit 31 registers the document 9 by storing and saving the document 9 uploaded from the computer 2 in the document storage unit 17 in a state where the registered user registered in the account information 27 is logged in. The identification information giving unit 32 gives unique identification information 8 to the document 9 registered by the registration unit 31.

  Thereafter, when the upload user instructs to share the document 9 with another user, the destination information input unit 33 receives input of destination information of the shared user who shares the document 9. The determination unit 34 performs user determination as to whether or not the shared user is a registered user by searching the account information 27 based on the shared user destination information received by the destination information input unit 33. Then, the sharing setting unit 35 writes the necessary information in the sharing information 28 and updates it so that the sharing user designated by the uploading user can print out the document 9 to update the sharing setting for the document 9. I do. At this time, based on the determination result of the determination unit 34, for example, if the sharing user is a registered user, the sharing setting unit 35 sets “A” as an output condition item to enable print output on the condition of login with account information. Is recorded. If the shared user is an unregistered user, “D” is recorded in the output condition item so that printing can be performed on the condition of login with identification information.

  However, even if the shared user is a registered user, the security level of the user ID and password registered in the account information 27 of the shared user may be lower than a certain level. For example, the user ID and password registered in the shared user account information 27 are less than a predetermined number of characters, or the password itself is empty. In such a case, if the print output of the document 9 is permitted by logging in with the account information of the shared user, a third party other than the shared user can obtain the printed material of the document 9 at the nearest convenience store relatively easily. There is a possibility that. In order to prevent this, when it is possible to specify that the shared user is a registered user, the determination unit 34 further determines the security level of the user ID and password included in the account information 27 of the registered user. If the security level is lower than a certain level, even a registered user is preferably handled in the same manner as an unregistered user.

  For example, when the security level of the user ID and password included in the registered user account information 27 is lower than a certain level, the sharing setting unit 35 changes the output condition when the shared user prints out the document 9, As with unregistered users, the print output is set to be permitted on condition that login with identification information is performed. Therefore, in this case, even if the shared user is a registered user, “D” is recorded in the output condition item in the shared information 28 in order to enable printout on the condition of login with the identification information.

  When the sharing setting is performed by the sharing setting unit 35, a plurality of documents 9 may be set to be shared for one shared user. In such a case, for example, when the shared user is a registered user and the shared user can print out all of the plurality of documents 9 by logging in to the document server 1 with his / her account information, the printing is performed. The operability at the time of output is significantly improved than before. However, when the shared user is an unregistered user, or when the shared user is a registered user, the document 9 cannot be printed out without logging in with the identification information as described above. Assuming that the shared user must input the identification information 8 given to each document 9 each time in order to print out all of the plurality of documents 9 as in the conventional case, the operability at the time of print output is assumed. Decreases.

  In order to suppress such a decrease in operability, the sharing setting unit 35 sets a login with identification information as an output condition for a shared user, and when the shared user shares a plurality of documents 9, A plurality of documents 9 are integrated into one. When login with identification information that matches any one of the plurality of identification information 8 assigned to each of the plurality of integrated documents 9 is permitted, the plurality of documents 9 integrated during the login are permitted. Set so that all of the items can be printed out. This eliminates the troublesomeness of the shared user having to input all of the identification information 8 assigned to each document 9 in order to print out all of the plurality of documents 9, thus improving operability. To do.

  However, when the login with the identification information 8 given to the document 9 is permitted, the logged-in user cannot be specified as described above. Therefore, when a plurality of shared users are set for each of the plurality of documents 9 to be integrated, it is preferable that the integration is performed on the condition that all of the plurality of shared users match. FIG. 9 is a diagram showing an integrated concept of a plurality of documents 9. In FIG. 9, four documents 9a, 9b, 9c, 9d uploaded by one user are registered in the document server 1, user A shares three documents 9a, 9b, 9d, and user B The case where two documents 9b and 9c are shared and user C shares only one document 9c is illustrated. In such a case, if all of the three documents 9a, 9b, 9d shared by the user A are integrated into one, the user B inputs the identification information 8b of the document 9b and logs into the document server 1. In such a case, the integrated three documents 9a, 9b, and 9c are all printed out by the user B, and a document 9d that is not shared by the user B is also printed out. If all of the two documents 9b and 9c shared by the user B are integrated into one, when the user C inputs the identification information 8c of the document 9c and logs in to the document server 1, the integrated 2 All of the two documents 9b and 9c are printed out by the user C, and the document 9b not shared by the user C is also printed out. In order to prevent the occurrence of such a problem, when the plurality of documents 9 are integrated into one, the sharing setting unit 35 sets a plurality of documents in which all the shared users set in each document 9 match each other. It is configured so that all documents are integrated and one document is excluded from the integration target when some shared users do not match. Therefore, in the case of FIG. 9, the sharing setting unit 35 integrates two documents 9a and 9d that are the same in that the shared user is only the user A, and integrates the other documents 9b and 9c. Will not. When the plurality of documents 9 are integrated into one as described above, the sharing setting unit 35 records the same ID in the integrated ID item of the sharing information 28.

  When the sharing setting by the sharing setting unit 35 is completed, the sharing notification unit 36 functions next, as shown in FIG. The sharing notifying unit 36 notifies the sharing setting of the document 9 by sending an e-mail EM1 to the sharing user of the document 9 based on the destination information received by the destination information input unit 33. Is a processing unit.

  Next, the output control unit 23 has functions as an output condition confirmation unit 41, a shared document extraction unit 42, and a data transmission unit 43, as shown in FIG. The output condition confirmation unit 41 is a processing unit that confirms the output condition of the document 9 shared by the shared user when the shared user logs in to the document server 1 with his / her account information. That is, even when the shared user logs in with his / her account information, if the security of the account information is low, as described above, the setting that cannot print out the document 9 without logging in with the identification information. It has become. Therefore, the output condition confirmation unit 41 confirms the output condition of the shared user who has logged in with his / her account information, and if he / she has to log in with the identification information, input the identification information given to the shared document 9. A prompt screen is transmitted to the printing apparatus 3. If the shared user logs in with his / her account information as a result of checking the output conditions, the screen for prompting the input of identification information is not transmitted.

  The shared document extraction unit 42 is a processing unit that extracts the shared document 9 that can be printed out by the shared user. When the shared user logs in with his / her account information, the shared document extraction unit 42 extracts all the shared documents 9 that can be printed out by the shared user. When the shared user is logged in with the identification information given to the document 9, the shared document extraction unit 42 extracts the shared document 9 that matches the identification information. However, when other documents are integrated with the shared document 9 that matches the identification information, the other documents are extracted at once. Then, the shared document extraction unit 42 generates a list screen or print screen of the extracted documents 9 and transmits it to the printing apparatus 3.

  The data transmission unit 43 is a processing unit that reads the document 9 from the document storage unit 17 and transmits it to the printing device 3 in response to receiving a print request specifying the document 9 to be downloaded from the printing device 3. The printing apparatus 3 prints out the document 9 downloaded from the document server 1 and provides it to the shared user.

  On the other hand, the deletion processing unit 24 shown in FIG. 6 is a processing unit that automatically deletes the document 9 registered in the document storage unit 17 by the registration processing unit 22 at a predetermined timing. For example, when the document 9 registered by the registration processing unit 22 is printed out, the deletion processing unit 24 automatically deletes the document 9 accordingly. However, when a plurality of shared users are set for one document 9, if the document 9 is deleted after only one print output, the other shared users cannot perform the print output. In such a case, the document 9 may be deleted when the number of times the document 9 is printed is the same as the number of shared users. In that case, since it is necessary to prevent the same user from performing print output a plurality of times, it is more preferable that the print output of the document 9 is permitted only once for each shared user. In addition, when such a configuration is adopted, it is necessary to specify who performed the print output even if the shared user is an unregistered user. (Mail address) may be accepted.

  Further, when the registration processing unit 22 registers the document 9, the storage period or the number of times of printing of the document 9 may be set. In this case, the deletion processing unit 24 deletes the document 9 when a preset storage period has elapsed or when a print output for a preset number of times of printing has been performed. Also good. Note that the storage period or the number of times of printing may be set to a predetermined default value or a value specified by the upload user.

  Next, a specific processing procedure performed in the document server 1 having the above configuration will be described. FIGS. 10 and 11 are flowcharts showing an example of a processing procedure executed when the document server 1 registers the document 9. This process is a process executed by the CPU 11 of the document server 1 based on the program 15.

  First, as shown in FIG. 10, the document server 1 stands by until account information is received via the network 4 (step S1). When the account information is received, it is determined whether or not the user is a registered user (step S2). ). As a result, if the user is not a registered user, the process returns to step S1. If the user is a registered user (YES in step S2), the document server 1 permits login based on the received account information, that is, login with a user account (step S3).

  When the registered user logs in as an upload user, the document server 1 determines whether or not a document registration operation has been performed by the upload user (step S4). If the registration operation is performed (YES in step S4), the document server 1 performs reception processing of the uploaded document 9 (step S5), and stores and registers the received document 9 in the document storage unit 17. (Step S6). Further, the document server 1 gives unique identification information 8 to the document 9 registered in the document storage unit 17 (step S7). If the registration operation is not performed in step S4, steps S5 to S7 are skipped and the process proceeds to step S8.

  Next, the document server 1 determines whether or not the upload user has instructed to share the document 9 (step S8), and executes the document sharing setting process when the sharing instruction has been issued (step S9). If no sharing instruction has been issued, step S9 is skipped and the process proceeds to step S10. Then, the document server 1 repeats the processes in and after step S4 until the upload user performs a logout operation. When the logout operation is performed, the document server 1 logs out the upload user and ends the process (step S10).

  FIG. 11 is a flowchart illustrating an example of a detailed processing procedure of the document sharing setting process (step S9). When this process is started, the document server 1 accepts the designation of the shared document 9 by the upload user (step S20), and accepts the e-mail address of the shared user who shares the designated shared document as destination information (step S21). . When receiving the destination information of the shared user, the document server 1 determines whether or not the shared user is a registered user (step S22).

  If the shared user is a registered user (YES in step S22), the security level of the user ID and password is confirmed with reference to the account information 27 of the shared user (step S23), and the security level is equal to or higher than a predetermined level. It is determined whether or not (step S24). If the security level is equal to or higher than the predetermined level (YES in step S24), the document server 1 performs setting for permitting print output of the shared document 9 when the shared user logs in with his / her account information (step S25). Then, the document server 1 notifies the sharing user that the sharing setting of the document 9 has been performed (step S26).

  On the other hand, if the shared user is not a registered user (NO in step S22), or if the shared user is a registered user and the security level of the user ID and password is below a predetermined level (NO in step S24), The document server 1 performs setting for permitting print output of the shared document 9 when the shared user logs in with the identification information given to the shared document 9 (step S27). Then, the document server 1 determines whether or not the plurality of documents 9 are shared by the shared server (step S28). When the plurality of documents 9 are shared, the plurality of documents 9 can be further integrated. It is determined whether or not (step S29). Here, it is confirmed whether or not there are two or more documents 9 in which other shared users are all the same users among the plurality of documents 9 shared by the user, and such two or more documents are Is present, it is determined that the two or more documents 9 can be integrated. As a result, if integration is possible (YES in step S29), the document server 1 performs document integration processing for integrating the two or more documents 9 (step S30). In this document integration process (step S30), the same integration ID is assigned to each of two or more documents 9 to be integrated. If the shared server does not share a plurality of documents 9 (NO in step S28), or if two or more documents 9 cannot be integrated (NO in step S29), the process of step S30 is performed. Absent. Thereafter, the document server 1 notifies the sharing user that the sharing setting of the document 9 has been performed, and ends the process (step S26).

  Next, FIG. 12 to FIG. 14 are flowcharts illustrating an example of processing procedures executed when the document server 1 performs print output based on a print request from the printing apparatus 3. This process is also a process executed by the CPU 11 of the document server 1 based on the program 15.

  First, as shown in FIG. 12, the document server 1 stands by until it receives account information or identification information transmitted from the printing apparatus 3 (NO in steps S40 and S41). When the account information is received (YES in step S40), the document server 1 determines whether or not the user is a registered user (step S42), and returns to step S40 if the user is not a registered user. If the user is a registered user (YES in step S42), the document server 1 determines whether or not the document 9 shared by the registered user exists (step S43). If there is no document 9 shared by the registered user (NO in step S43), the process returns to step S40. On the other hand, when the document 9 shared by the registered user exists (YES in step S43), the document server 1 determines the output condition of the shared document 9 (step S44) and shares it by logging in with account information. It is determined whether or not the setting is to permit printing output of the document 9 (step S45). As a result, if the setting is to permit print output if logged in with account information (YES in step S45), the document server 1 permits login based on the shared user's own account information, that is, login with the user account (step S45). S46). On the other hand, if it is not set to permit print output when logging in with account information (NO in step S45), the processing by the document server 1 proceeds to step S48.

  On the other hand, when the document server 1 receives the identification information transmitted from the printing apparatus 3 (YES in step S41), the document server 1 determines whether or not the document 9 corresponding to the identification information exists (step S47). If there is no document 9 corresponding to the received identification information (NO in step S47), the process returns to step S40. On the other hand, when the document 9 corresponding to the identification information exists and the document 9 can be specified (YES in step S47), the document server 1 permits login with the identification information (step S51). ).

  Further, when the process proceeds from step S45 to S48, the document server 1 generates an identification information input guidance screen and transmits it to the printing apparatus 3 (step S48). And it waits until the identification information input by the sharing user is received from the printing apparatus 3 (step S49). When the document server 1 receives the identification information from the printing apparatus 3 (YES in step S49), the document server 1 determines whether there is a document 9 corresponding to the identification information (step S50), and the document 9 corresponding to the identification information. Can be specified (YES in step S50), login with the identification information is permitted (step S51).

  FIG. 13 is a flowchart illustrating an example of a processing procedure performed when a shared user logs in with his / her account information. When proceeding to this process, the document server 1 extracts all the documents 9 that can be printed out by the shared user (step S60). Then, a list screen of documents 9 that can be printed out by the shared user is generated and transmitted to the printing apparatus 3 (step S61). Thereafter, the process waits until the document 9 to be downloaded is designated from the printing apparatus 3 (step S62). When the document 9 is designated, the designated document 9 is transmitted to the printing apparatus 3 (step S63). When the print completion notification is received from the printing apparatus 3 (YES in step S64), the document server 1 performs a setting for prohibiting the second and subsequent print output of the document 9 by the shared user (step S65). ). Further, the document server 1 determines whether or not there is another document 9 that the shared user has not yet printed out (step S66), and if there is another document 9, returns to step S61. On the other hand, if there is no other document 9 (NO in step S66), the process ends.

  FIG. 14 is a flowchart illustrating an example of a processing procedure performed when a shared user logs in with identification information. When proceeding to this process, the document server 1 extracts the shared document 9 that matches the identification information input by the shared user (step S70), and determines whether the shared document 9 has a document integration setting. (Step S71). If there is a setting for document integration (YES in step S71), the document server 1 extracts all of the two or more integrated documents 9 based on the integration ID (step S72). Then, a list screen of the two or more documents 9 is generated and transmitted to the printing apparatus 3 (step S73). If there is no document integration setting, steps S72 and S73 are skipped.

  Then, the document server 1 waits until a print request is received from the printing apparatus 3 (step S74). When the print request is received, the document 9 specified by the print request is transmitted to the printing apparatus 3 (step S75). When the print completion notification is received from the printing apparatus 3 (YES in step S76), the document server 1 performs a setting for prohibiting the second and subsequent print output of the document 9 by the shared user (step S77). ). At this time, the document server 1 requests the shared user to input destination information as necessary, and identifies the shared user based on the destination information. Further, the document server 1 determines whether or not there is another integrated document 9 that the shared user has not yet printed out (step S78). If there is another integrated document 9, the process returns to step S73. On the other hand, if there is no other integrated document 9 (NO in step S78), the process ends.

  Next, FIG. 15 is a flowchart illustrating an example of a processing procedure executed when the document server 1 deletes the registered document 9. This process is also a process executed by the CPU 11 of the document server 1 based on the program 15, for example, a process repeatedly executed by the CPU 11 at a constant cycle. When starting this process, the document server 1 determines whether or not the document 9 is registered in the document storage unit 17 (step S80). As a result, if the document 9 is not registered (NO in step S80), this process ends. On the other hand, when the document 9 is registered (YES in step S80), the document server 1 determines whether or not the document 9 has a retention period (step S81), and the retention period is set. If there is (YES in step S81), it is determined whether or not the storage period after registration has passed (step S82). If the storage period has elapsed, the document 9 is deleted (step S83).

  Further, the document server 1 determines whether or not the document 9 has a print count setting (step S84). If the print count is set (YES in step S84), the set predetermined number of print outputs is made. Is determined (step S85). If the predetermined number of print outputs have been executed, the document 9 is deleted (step S86).

  Further, when the number of times of printing is not set in the document 9 (NO in step S84), the document server 1 checks whether or not the document 9 has been printed out (step S87). If the print output is performed (YES in step S87), it is determined whether another user different from the user who performed the print output of the document 9 exists as a shared user (step S88). If another shared user exists, the process is terminated as it is. If no other shared user exists, the document 9 is deleted (step S89). Note that when the number of times of printing is set and the number of times of printing output has not yet reached the predetermined number of times, step S89 may be skipped and the storage state of the document 9 may be continued.

  As described above, when the document server 1 of the present embodiment registers the document 9 to be uploaded while the registered user registered in the account information 27 is logged in, the document server 1 gives the unique identification information 8 to the document 9. To do. When the registered user inputs the destination information of the shared user who shares the document 9, it is determined whether or not the shared user is the registered user by determining whether or not the destination information is registered in the account information 27. Determine whether. Further, based on the determination result, the document server 1 prints out the document 9 on condition that the account information of the shared user is input when the destination information of the shared user is registered in the account information 27. When the shared user's destination information is not registered in the account information 27, the identification information 8 given to the document 9 is input by the shared user. In this configuration, the print output is permitted.

  According to the above configuration, when a registered user registered in advance in the account information 27 downloads the document 9 from the document server 1 and prints it out, the registered user inputs his / her own account information that he / she is familiar with. By logging in to the document server 1, it is possible to print out the document 9 set to be shared. For this reason, if the shared user is a registered user of the document server 1, it is not necessary to input the unique identification information 8 given when registering the document 9 as in the conventional case, so that an input error is unlikely to occur and the operability is improved. There is an advantage of doing. Further, according to the above configuration, the document 9 can be shared not only by registered users registered in advance in the account information 27 but also by unregistered users who are not registered in the account information 27, which is highly convenient. There is also an advantage.

  In addition, when the destination information of the shared user who shares the registered document 9 is not input, the document server 1 of the present embodiment sets a state in which only the user who uploaded the document 9 can print out. Therefore, the registered user can store and manage only the document 9 used by the registered user in the document server 1.

  Further, when the shared user destination information is registered in the account information 27, the document server 1 according to the present embodiment notifies that the sharing setting of the document 9 has been performed based on the destination information, and the shared user destination is notified. When the information is not registered in the account information 27, it is notified that the sharing setting of the document 9 has been performed based on the destination information, and the identification information 8 given to the document 9 is notified. Therefore, the registered user and the unregistered user can grasp that the document 9 that can be used by the user is registered in the document server 1. In particular, an unregistered user can acquire identification information necessary for printing out the document 9.

  Further, when the document server 1 of the present embodiment performs setting for permitting print output of the document 9 on condition that the identification information 8 is input by the sharing user, the sharing user shares the plurality of documents 9. On the condition that any one of the plurality of identification information 8 assigned to each of the plurality of documents 9 is input, a setting for permitting the print output of the plurality of documents 9 is performed. Therefore, even when the shared user inputs the identification information 8 and prints out the document 9, it is not necessary to individually input the plurality of identification information 8 assigned to each of the plurality of documents 9. Significantly improved.

  Further, when the document server 1 of the present embodiment performs setting for permitting print output of the document 9 on condition that the identification information 8 is input by the sharing user, the sharing user shares the plurality of documents 9. Among the plurality of documents 9 shared by the shared user, two or more documents 9 in which other shared users are all the same user are integrated, and two or more given to each of the integrated two or more documents 9 On the condition that any one of the identification information 8 is input, a setting for permitting print output of two or more integrated documents 9 is performed. Therefore, only the same shared user can print out the two or more integrated documents 9, and when printing out the two or more integrated documents 9, it is given to each of the two or more documents 9. Since it is not necessary to input the two or more pieces of identification information 8 individually, the operability is remarkably improved.

  Further, the document server 1 of the present embodiment is configured to allow each shared user to print out the document 9 only once when a plurality of shared users are set for one document 9. The Therefore, it is possible to prevent the document 9 from being repeatedly printed out by each shared user. In addition, according to this configuration, the document 9 can be deleted from the document server 1 when all of the plurality of shared users perform print output once.

  The document server 1 according to the present embodiment determines the security level of the shared user account information 27 when the shared user account information 27 is registered. 9 changes the conditions for performing printout. Specifically, on the condition that the identification information 8 given to the shared document 9 is input by the shared user, the setting is changed to allow the printout of the shared document 9. Therefore, the shared document 9 can be prevented from being printed out by an unexpected third party, and the security of the shared document 9 can be ensured.

  In addition, the document server 1 of the present embodiment is configured to automatically delete the registered document 9 at a predetermined timing. Therefore, the document 9 that is forgotten without being deleted is not stored in the document server 1 for a long time. Such automatic deletion is performed, for example, when the print output of the document 9 is completed. Therefore, the document 9 that is no longer needed after the print output is completed can be quickly deleted from the document server 1. it can. In addition, when the document 9 is registered, a retention period or the number of times of printing of the document 9 is set, and the document 9 is deleted when the retention period elapses or when printing output is performed for the number of times of printing. By configuring so, it is possible to favorably prevent the document 9 from being stored in the document server 1 over a long period of time.

(Modification)
As mentioned above, although one embodiment related to the present invention was described, the present invention is not limited to the contents described in the above embodiment, and various modifications can be applied. Some examples will be described below.

  For example, in the above-described embodiment, the case where the printing apparatus 3 on which the shared user performs printout is installed in the convenience stores 5a, 5b, 5c, and the like has been described. However, the present invention is not limited to this. For example, the printing apparatus 3 may be installed in a store other than a convenience store, a public facility, or the like. The printing apparatus 3 may be an office dedicated machine installed in a shared user's office or the like.

  In the above-described embodiment, an example has been described in which when the security level of the account information 27 of the shared user is lower than a predetermined level, the output condition when the shared user prints the shared document 9 is changed. However, if the output condition is changed, even though the shared user is a registered user, the shared user must input identification information 8 that is not familiar to the user, and input errors are likely to occur. Therefore, when the security level of the account information 27 of the shared user is lower than a predetermined level, the shared user may be notified to urge the change of the account information 27 by the email EM1. In this case, the shared user himself / herself resets the user ID and password included in the account information 27 and changes the security level to be equal to or higher than the predetermined level. You can print out by logging in. That is, in this case, since the output condition is not changed, a decrease in operability can be suppressed.
