Even when printing the screen of such a shared terminal with a printing device such as an MFP (Multifunction Peripheral / Printer / Product) connected by a communication network or the like, paper output is performed after authentication in front of the printing device. It is desirable to do. On the other hand, in the important person class, a reliable person such as a secretary often takes over the work.

However, people in the important person class often have meetings and may not be able to afford to go to the printing device to get the printed matter. In addition, if a person other than a reliable person such as a secretary goes to pick up the printed matter, a security problem will occur.

In order to solve the above-mentioned problems, the invention according to claim 1 is a shared terminal that displays an image that can be viewed by a plurality of users, from the first exclusive terminal of a specific user to the first. The acquisition means for acquiring the first terminal identification information for identifying the exclusive terminal, the predetermined terminal identification information for identifying the predetermined exclusive terminal, and the predetermined user name of the user of the predetermined exclusive terminal. The transmission means for transmitting the login authentication request together with the first terminal identification information acquired by the acquisition means to the terminal management server associated and managed, and the terminal management server based on the transmission by the transmission means. Login authentication is performed by determining whether the first terminal identification information is managed, and when the login is successful, the user name of the user of the first dedicated terminal transmitted from the terminal management server is used. Receiving means for receiving a certain first user name, display control means for displaying a print setting screen for setting print parameters when printing the image, and setting of print parameters on the print setting screen. It has a receiving means for receiving, and the transmitting means is set on the data related to a predetermined image, a predetermined user name related to a user of the predetermined exclusive terminal as a printer name, and the print setting screen. The data related to the image, the first user name, and the set specific print parameters are transmitted to the print server that manages the predetermined print parameters in association with each other, and the reception means is the first. When the other user name, which is the user name of another user who is not the user, is accepted, the transmission means transmits the other user name in addition to the first user name . When the display control means is displaying the print setting screen and the acquisition means acquires the second terminal identification information different from the first terminal identification information, the transmission means is said. The second terminal identification information acquired by the acquisition means is transmitted to the terminal management server, and the receiving means manages the terminal based on the transmission of the second terminal identification information by the transmission means. Upon receiving the second user name, which is the user name of the user of the second dedicated terminal transmitted from the server, the display control means displays the print setting screen on the print setting screen as the first user name. It is a shared terminal characterized by changing and displaying from the user name of the user to the received second user name .

Then, the transmission / reception unit 21 of the electronic blackboard 2x transmits an authentication request for the IC card 3 to the terminal management server 5 (step S53). This authentication request includes the terminal ID of the IC card 3 acquired by the acquisition / providing unit 28. As a result, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the terminal ID (step S54). Specifically, the storage / reading processing unit 59 uses the terminal ID received in step S53 as a search key to search the terminal management table (FIG. 12A) for the user name corresponding to the terminal ID. If there is a corresponding user name, the authentication unit 52 determines that it is a legitimate IC card (terminal ID). If there is no corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2x (step S55). When the authentication unit 52 determines that the IC card is legitimate, the authentication result includes information indicating that the card is legitimate and the user name. Further, when the authentication unit 52 determines that the IC card is not legitimate, the authentication result includes information indicating that the card is not legitimate. As a result, the transmission / reception unit 21 of the electronic blackboard 2x receives the authentication result.

Next, the electronic blackboard 2x performs a process based on the authentication result (step S56). Here, the process based on the authentication result in step S56 will be described in detail with reference to FIG. 20. FIG. 20 is a flowchart showing a process based on the authentication result in the case of printing.

As shown in FIG. 20, the determination unit 25 is information indicating that the examination result received in step S55 is valid (that is, is the terminal ID transmitted in step S53 valid? ) Is determined (step S56-1). When the determination unit 25 determines that the information is not valid (NO), the display control unit 24 displays an error screen on the display 220 as shown in FIG. 14 (B). 180 is displayed (step S56-2). Further, when the determination unit 25 determines that the information is valid (YES), the user ID received in step S55 is the user ID of the logged-in user A. It is determined whether they are the same (step S56-3). Then, if the determination unit 25 determines that they are the same (YES), the process proceeds to step S57, which will be described later. On the other hand, if the determination unit 25 determines that they are not the same (NO), the setting unit 27 changes the printer name to the user name received in step S55 (step S56-4). For example, when the display control unit 24 is displaying the print setting screen 260 shown in FIG. 9D, the logged-in user A brings his / her IC card 3 close to the short-range communication unit 221. , The printer name remains "Kato" and is not changed. On the other hand, when the display control unit 24 is displaying the print setting screen 260 shown in FIG. 9D, the user B who is not logged in uses his / her smartphone 4 on the short-range communication unit 221. In close proximity, the printer name is changed from "Kato" to "Jim", as shown in FIG. Then, after the processing of step 56-4, the process proceeds to step S57.

Next, returning to FIG. 19, the reception unit 22 of the electronic blackboard 2x has print setting parameters such as color or black and white by the electronic pen 2500 from the user A in FIG. 9 (D) or from the user B in FIG. 22. By accepting the setting of, printing acceptance processing is performed (step S57). Here, the print acceptance process of step S57 will be described in detail with reference to FIG. 21. FIG. 21 is a flowchart showing a print acceptance process.

First, on the print setting screen 260 (see FIG. 9D), the reception unit 22 accepts that the "print" button 267 or the "other printer setting" button 268 is pressed by the user A (step). S57-1).

Next, the determination unit 25 determines whether to set another user as the printer by determining whether the "other printer setting" button 268 has been pressed (step S57-2). When the "other printer setting" button 268 is pressed, that is, when the determination unit 25 determines that another user is set as the printer (YES), the display control unit 24 sets the display control unit 24 in FIG. 10 (D). ) Is displayed (step S57-3).

On the printer setting screen 300, a printer input field 301 for inputting a printer name and a "print" button 307 pressed by the user when starting printing are displayed. Further, on the printer setting screen 300, a "cancel" button 309 for returning to the print setting screen 260 shown in FIG. 9D is displayed. Then, when the user wants another user such as a secretary to go to pick up the printed matter, he / she inputs another user name C (for example, Mary) in the printer input field 301 and presses the "print" button 307. By pressing, the reception unit 22 accepts the input of another user name and the pressing of the "print" button 307 (step S57-4). As a result, the print acceptance process in step S57 ends.

On the other hand, when the "print" button 267 is pressed in step S57-2, that is, when the determination unit 25 determines that another user is not set as the printer (NO), printing in step S57. The reception process is completed.
Accepting the press of the "print" button 267 (step S57). As a result, the creation unit 26b creates print data as PDL format image data from the bitmap format drawing image data obtained by drawing by the users A and B (step S58).

Next, the transmission / reception unit 21 of the electronic blackboard 2x transmits the print data created in step S58 to the print server 8 (step S59). This print data includes information related to the print data (printer name, file name, and print setting parameters). As a result, the transmission / reception unit 81 of the print server 8 receives the print data. When the "print" button 267 is pressed in step S57-1, the printer name in the information related to the print data is the user name (Kato) of the user A. Further, in step S57-4, when another user name (Mary) is input to the printer input field 301 and the "print" button 307 is pressed, the information related to the print data is included. The printer name is the user name (Kato) of the user A and the user name (Mary) of another user C.

Next, the storage / reading processing unit 89 of the print server 8 stores the print data received in step S59 in the storage unit 8000 (step S60). Further, the storage / reading processing unit 89 refers to the print data management table (see FIG. 12C) with information related to the print data received in step S59 (printer name, file name, and print setting parameters). ) By associating and storing (step S61). When the printer name in the information related to the print data is the user name (Kato) of the user A and the user name (Mary) of another user C, the print data management table (FIG. 12 (FIG. 12). It is shown in the record in the fourth column of C)). As a result, in the print process of step S80 described later, the user C can go to the installation location of the MFP 9 instead of the user A and print the print data of the user A.
From the above, the print preparation process is completed.

Subsequently, a case of final printing will be described with reference to FIGS. 23 and 24. FIG. 23 is an image diagram showing a state in which the user uses the MFP. FIG. 24 is a sequence diagram showing the printing process of the drawn image data. Here, a case where the user A prepares for printing in the print preparation process (steps S51 to S61) will be described.

Then, the transmission / reception unit 91 of the MFP 9 transmits an authentication request for the IC card 3 to the terminal management server 5 (step S72). This authentication request includes the terminal ID of the IC card 3 acquired by the acquisition / providing unit 98. As a result, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the terminal ID (step S73). Specifically, the storage / reading processing unit 59 uses the terminal ID received in step S72 as a search key to search the terminal management table (FIG. 12A) for the user name corresponding to the terminal ID. If there is a corresponding user name, the authentication unit 52 determines that it is a legitimate IC card (terminal ID). If there is no corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the MFP 9 (step S74). When the authentication unit 52 determines that the IC card is legitimate, the authentication result includes information indicating legitimacy, a user ID, and a user name. Further, when the authentication unit 52 determines that the IC card is not legitimate, the authentication result includes information indicating that the card is not legitimate. As a result, the transmission / reception unit 91 of the MFP 9 receives the authentication result.

Next, the MFP 9 performs a process based on the authentication result (step S75). Specifically, if the determination unit 95 determines the content of the authentication result and determines that the authentication result contains information indicating that the authentication result is not valid, printing is not performed, but the authentication result indicates that the authentication result is valid. If it is determined that the information to be shown is included, the process proceeds to step S76. Hereinafter, the case where the authentication result contains information indicating that it is valid will be continued.

The transmission / reception unit 91 of the MFP 9 transmits a print data request to the print server 8 (step S76). This request includes the user name received in step S74. As a result, the transmission / reception unit 81 of the print server 8 receives the request for print data.

Next, in the print server 8, the storage / reading processing unit 89 responds by searching the print data management table (see FIG. 12C) using the user name received in step S74 as a search key. Read the file name (step S77). Further, the storage / reading processing unit 89 reads out the print data of the file name read in step S77 from the storage unit 9000 (step S78). Then, the transmission / reception unit 81 transmits print data to the MFP 9 (step S79). This print data includes the user name received in step S76. As a result, the transmission / reception unit 91 of the MFP 9 receives the print data.

Next, in the MFP 9, the printing unit 93 prints an image on printing paper based on the print data and outputs the image (step S80). In steps S76 and S79, the user name is transmitted and received, but the user name may be used. In this case, in step 77, the user ID is used as the search key. With the above, the printing process is completed.

<< Main effects of the embodiment >>
As described above, according to the present embodiment, even if it is a shared terminal such as an electronic blackboard 2x that can be shared by a plurality of users, the terminal such as an IC card used for login is exclusively used. This has the effect of ensuring security.

Further, while realizing proxy printing (see FIGS. 9 (D) and 10 (D)), it has the effect that security can be ensured by a dedicated terminal such as an IC card 3.

Further, when the logged-in user A brings his / her IC card 3 close to the electronic blackboard 2x, the process proceeds to the display of the end screen 238 (see FIG. 8 (C)) (see S96-4), and the user B who is not logged in When the user's smartphone 4 is brought close to the electronic blackboard 2x, the process proceeds to the display of the error screen 180 (see FIG. 14B) (see S96-2). As a result, the user A who has easily logged in in the vicinity of the IC card 3 can easily log out in the vicinity of the IC card 3. Further, the electronic blackboard 2x can ensure security by not accepting logout even if the user B who is not logged in brings the smartphone 4 close to the electronic blackboard 2.

Further, since the setting unit 27 sets the e-mail address of the logged-in user A as the sender e-mail address and the destination e-mail address (see S20), the user A can easily set the sender and the destination. Can be done. Further, when the destination setting screen 270 (see FIG. 10A) is displayed and the non-logged-in user B brings his / her smartphone 4 close to the electronic blackboard 2x, the display control unit 24 displays the destination setting screen. The e-mail address of user B is additionally displayed on 270 (see FIG. 14D) (see S40). As a result, when the user B wants to send the drawn image data to his / her own PC10b, he / she does not have to bother to input or select his / her own e-mail address, so that the trouble of setting the e-mail address can be saved.

Further, the setting unit 27 sets the user name of the logged-in user A as the printer name, and the display control unit 24 sets the user name of the logged-in user A as the printer name on the print setting screen 260. It is displayed (see S51). As a result, the user A can easily set the printer name. Further, when the print setting screen 260 (see FIG. 9D) is displayed and the non-logged-in user B brings his / her smartphone 4 close to the electronic blackboard 2x, the display control unit 24 displays the print setting screen. The printer name of 260 (see FIG. 22) is changed and displayed from the user name of the logged-in user A to the user name of the user B (S56-4). As a result, even if the user B who is not logged in wants to print the drawn image data, the drawing image data can be easily printed. That is, when the user adopts secure print in which printing is not started unless the user moves to the installation location of the MFP 9 and is close to his / her own terminal, the user B who has not logged in tries to print and his / her smartphone is used for the MFP 9. Printing is not possible even if 4 (proprietary terminal) is in close proximity. However, in the present embodiment, if the user B brings his / her smartphone 4 (proprietary terminal) close to the electronic blackboard 2x, the printer becomes the user B, so that the user B is not logged in. It is also possible to print by secure printing.

Further, even on the print setting screen 260 shown in FIG. 22, the "other printer setting" button 268 is still displayed. By this. User B (Jim) can have another user D, such as his secretary, perform printing on his behalf. In addition, since both user A (B) and other user C (D) can print, even if the other user C (D) cannot act on their behalf, it can be used. Person A (B) can go to pick up the printed matter by himself / herself.

<< Others >> (1) Next, another example of processing or operation will be described with reference to FIG. 27. FIG. 27 is a sequence diagram showing another example of the login process. In this embodiment, instead of the processes of steps S13 and S14 shown in FIG. 13, the processes of steps S113 to S117 are executed. Therefore, the processes of steps S113 to S117 will be described below. A plurality of terminal management servers 5 may be installed.

First, in step S12 shown in FIG. 13, when the acquisition / provision unit 28 of the electronic blackboard 2x acquires the terminal ID of the IC card from the acquisition / provision unit 38 of the IC card 3, the electronic blackboard in FIG. 27. The 2x transmission / reception unit 21 transmits the connection key k1 to the terminal management server 5 (step S113). As a result, the transmission / reception unit 51 of the terminal management server 5 is issued as a client of the terminal management server 5 in which the connection key k1 holds the information to be authenticated, and is stored in the storage unit 2000 of the electronic blackboard 2x in advance. Has been done.

On the other hand, the issued connection key k2 is also stored in the storage unit 5000 on the terminal management server 5. Then, the determination unit 55 of the terminal management server 5 determines whether or not access is possible by determining whether or not the received connection key k1 and the stored connection key k2 are the same (step S114). When the connection key k1 and the connection key k2 are the same, the determination unit 55 determines that the access is possible. If the connection key k1 and the connection key k2 are not the same, the determination unit 55 determines that the access is inaccessible.

Next, the transmission / reception unit 51 of the terminal management server 5 transmits the determination result to the electronic blackboard 2x (step S115). When the determination unit 55 determines that the access is possible, the determination result includes information indicating that the determination unit 55 is accessible and the access information a1. Further, when the determination unit 55 determines that the access is inaccessible, the determination result includes information indicating that the access is inaccessible. As a result, the transmission / reception unit 21 of the electronic blackboard 2x receives the determination result. The access information a1 is, for example, a unique random alphanumerical string such as 16 characters, 32 characters, 64 characters, etc., and when it is determined by the determination unit 55 that it can be accessed, the determination unit 55 is subsequently determined. Information generated by. The generated access information a1 is temporarily stored in the storage unit 5000 by the storage / reading processing unit 59.

Next, the electronic blackboard 2x performs a process based on the determination result (step S116). As an example of this process, when the determination result includes information indicating that it is inaccessible, the display control unit 24 displays on the display 220 that it is inaccessible. If the determination result contains information indicating that the determination result is accessible, the process proceeds to step S117. Hereinafter, the case where access is possible will be continued.

The transmission / reception unit 21 of the electronic blackboard 2x transmits an authentication request to the terminal management server 5 (step S117). This authentication request includes the terminal ID acquired in step S12 and the access information a2. As a result, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the access information a2 and the terminal ID (step S118). Specifically, the determination unit 55 determines whether or not the received access information a2 and the access information a1 temporarily stored in the storage unit 5000 match, and determines that they match. If so, the authentication unit 52 further executes the authentication process in the same manner as in step S14 described above. On the other hand, when the determination unit 55 determines that the received access information a2 and the access information a1 temporarily stored in the storage unit 5000 do not match, the authentication unit 52 performs authentication processing. Without executing, the transmission / reception unit 51 transmits information indicating that it is not valid to the electronic blackboard 2x. Since this process and subsequent processes are the same as the processes after step S14 in the first embodiment, the description thereof will be omitted.

After the process of step S114, the transmission / reception unit 51 may encrypt the access information and then perform the transmission of step S115.
