The first determination process is a process in which, when the communication unit 43 receives an e-mail, it analyzes the e-mail and determines whether or not the sender's e-mail address (From) of the e-mail exists in the table TB1. In the storage process, when it is determined in the first determination process that the sender's email address exists in the table TB1, the user information linked to the sender's email address is obtained from the table TB1 and linked to the obtained user information. This is a process of storing the attached file in the second storage unit 44B.

The authentication process is a process of authenticating user information input from the touch panel 41. Specifically, in the authentication process, control unit 45 determines whether the user ID and PIN code input from touch panel 41 match the user ID and PIN code stored in table TB1.

The printing process is a process of printing, using the printing unit 42, the attached file stored in the second storage unit 44B in association with the user information authenticated by the authentication process.

The second determination process determines whether the subject of the email matches the user information registered in the table TB1 when it is determined in the first determination process that the sender email address does not exist in the table TB1. This is the process of determining. Specifically, in the second determination process, the control unit 45 determines whether the user ID input as the subject of the email matches the user ID registered in the table TB1.

In the registration process, when it is determined in the second determination process that the subject of the e-mail matches the user ID, the user ID that matches the subject, the sender's e-mail address, and the attached file are linked and stored in the storage unit 44. This is the process of storing the data in the . The registration process includes a temporary registration process, a display process, and an actual registration process.

In the temporary registration process, when the subject of the email is determined to match the user ID in the second determination process, the user ID that matches the subject, the sender's email address, and the attached file are linked and temporarily registered. This is a process of storing in table TB2. Specifically, in the temporary registration process, the control unit 45 registers the sender email address in the temporary registration table TB2 as a candidate email address to be officially registered in the table TB1. Further, in the temporary registration process, the control unit 45 registers the file name of the attached file in the temporary registration table TB2, and stores the attached file in a storage area different from the temporary registration table TB2 in the second storage unit 44B. do.

In the display process, if the user ID authenticated by the authentication process and the user ID stored in the temporary registration table TB2 match, the sender email address stored in the temporary registration table TB2 is registered in the table TB1. This is a process of displaying on the touch panel 41 a screen for selecting whether or not to register (see address registration screen G11 in FIG. 7).

This registration process is performed when information (YES) indicating that the sender email address is to be registered in table TB1 is input on the touch panel 41 on the address registration screen G11 (see FIG. 7) described above. This is a process of registering the sender email address in the temporary registration table TB2, which is linked to the user information, in the table TB1.

Furthermore, the control unit 45 provides a function to print the attached file using the printing unit 42 when information indicating that the attached file is to be printed (YES) is input on the touch panel 41 on the print selection screen G12 described above. have.

Next, details of the operation of the control section 45 will be explained using flowcharts shown in FIGS. 3 to 5. The control unit 45 repeatedly executes the main loop process shown in FIG.

In the main loop process, the control unit 45 first starts counting the time until email check (S1). Here, the mail check is a process of inquiring the mail server 3 whether an e-mail whose destination is the mail address of the printing device 4 (hereinafter also referred to as "received mail") exists in the mail server 3. Email checking is performed at predetermined intervals.

After step S1, the control unit 45 determines whether it is time to perform a mail check (S2). If it is determined in step S2 that it is time to execute the mail check (Yes), it is checked whether there is any received mail in the mail server 3 (S3). Specifically, in step S3, the control unit 45 accesses a predetermined mailbox allocated for the printing device 4 in the mail server 3.

After step S3, the control unit 45 determines whether there is any unreceived received mail in the mail server 3 (S4). If it is determined in step S4 that there is an unreceived received email (Yes), the control unit 45 receives the unreceived email and executes email analysis processing (S5). Note that the email analysis process will be described in detail later.

After step S5, or if the determination is No in step S4, the control unit 45 starts counting the time until the email check (S6). After step S6, the control unit 45 returns to the process of step S2.

If it is determined in step S2 that it is not time to perform the email check (No), the control unit 45 determines whether or not the touch panel 41 has been operated (S7). If it is determined in step S7 that the touch panel 41 has been operated (Yes), the control unit 45 determines whether or not the operation on the touch panel 41 is for logging into the printing device 4 (S8). .

If it is determined in step S8 that the operation on the touch panel 41 is an operation for logging in (Yes), the control unit 45 executes a login process (S9). Note that the login process will be described in detail later. After step S9, the control unit 45 returns to the process of step S2.

If it is determined in step S7 that the touch panel 41 is not being operated (No), or if it is determined in step S8 that the user is not logged in (No), the control unit 45 executes other processing. (S10), and the process returns to step S2. Here, other processing includes, for example, processing in which the printing unit 42 prints a FAX received by the printing device 4.

As shown in FIG. 4, in the email analysis process, the control unit 45 first checks the sender email address of the received email (S21). Specifically, in step S21, the control unit 45 acquires the sender's email address from the received email.

After step S21, the control unit 45 determines whether the acquired sender email address matches the email address registered in the table TB1 (S22). Here, the process of step S22 is the first determination process described above.

If it is determined in step S22 that the sender's e-mail address matches the e-mail address in table TB1, that is, the sender's e-mail address is already registered in table TB1 (Yes), the control unit 45 controls the sender's e-mail address. The user ID corresponding to the email address in table TB1 that matches the address is confirmed and details are acquired (S23).

After step S23, the control unit 45 stores the user ID acquired in step S23, the file name of the attached file corresponding to the sender email address acquired in step S21, and the candidate flag "NO" in the temporary registration table TB2. (S24).

Here, the candidate flag is a flag for specifying the sender email address as a candidate to be registered in the table TB1. When the candidate flag is YES (specifically, "1"), it indicates that the sender's e-mail address is designated as a candidate to be registered in table TB1. Further, when the candidate flag is NO (specifically, "0"), it indicates that the sender's e-mail address is not designated as a candidate to be registered in the table TB1.

After step S24, the control unit 45 links the attached file corresponding to the sender email address acquired in step S21 with the information registered in the temporary registration table TB2, such as the file name and user ID, and prints it as print data. 2 storage section 44B (S25). Here, the process of step S25 is the accumulation process described above. After step S25, the control unit 45 returns to the main loop process (RETURN).

If it is determined in step S22 that the sender's e-mail address does not match the e-mail address in the table TB1, that is, the sender's e-mail address is not registered in the table TB1 (No), the control unit 45 selects the subject of the e-mail. It is determined whether or not the user ID matches the user ID in table TB1 (S26). Here, the process of step S26 is the second determination process described above.

If it is determined in step S26 that the subject matches the user ID in table TB1 (Yes), the control unit 45 sends the user ID obtained in step S23, the sender email address obtained in step S21, and the corresponding The file name of the attached file corresponding to the sender's e-mail address and the candidate flag "YES" are stored in the temporary registration table TB2 (S27). Here, the process of step S27 is the above-mentioned temporary registration process. After step S27, the control unit 45 moves to the process of step S25.

If it is determined in step S26 that the subject does not match the user ID in table TB1 (No), the control unit 45 deletes the e-mail and the attached file attached to the e-mail (S28). After step S28, the control unit 45 returns to the main loop process (RETURN).

As shown in FIG. 5, in the login process, the control unit 45 first holds (stores) the user ID and PIN code input from the touch panel 41 in the second storage unit 44B (S41). After step S41, the control unit 45 determines whether the user ID and PIN code input from the touch panel 41 are in the table TB1 (S42). Here, the process of step S42 is the authentication process described above.

If it is determined in step S42 that the user ID and PIN code are not in the table TB1 (No), the control unit 45 displays an error message such as that the PIN code is incorrect on the touch panel 41, and then returns to the main loop process. Return (RETURN). If it is determined in step S42 that the user ID and PIN code are in the table TB1 (Yes), it is determined whether the data of the logged-in user is registered in the temporary registration table TB2 (S43). Specifically, in step S43, the control unit 45 determines whether a user ID that matches the authenticated user ID, a file name and a sender email address associated with the user ID are registered in the temporary registration table TB2. Determine.

If it is determined in step S43 that the data of the logged-in user is registered in the temporary registration table TB2 (Yes), the control unit 45 determines whether the candidate flag in the data of the user is "YES" or not. is determined (S44). If it is determined in step S44 that the candidate flag is "YES" (Yes), the control unit 45 links the sender email address registered in the temporary registration table TB2 with the authenticated user ID. , an address registration screen G11 (see FIG. 7) for selecting whether to register in table TB1 is displayed on touch panel 41 (S45). Here, the process of step S45 is the display process described above.

After step S45, the control unit 45 determines whether YES is selected on the address registration screen G11 (S46). If it is determined that YES is selected in step S46 (Yes), the control unit 45 registers the sender email address registered in the temporary registration table TB2 in the table TB1 in association with the authenticated user ID. (S47), and the process moves to step S48. Here, the process of step S47 is the above-mentioned main registration process. If it is determined that NO is selected in step S46 (No), the control unit 45 skips step S47, that is, moves to step S48 without executing the main registration process.

In step S48, the control unit 45 displays a print selection screen G12 (see FIG. 7) on the touch panel 41 for selecting whether to print the attached file with the file name associated with the authenticated user ID (S48). . After step S48, the control unit 45 determines whether YES is selected on the print selection screen G12 (S49).

If it is determined that YES has been selected in step S49 (Yes), the control unit 45 prints the attached file with the file name associated with the authenticated user ID (S50). Here, step S50 is the printing process described above. Note that in the printing process, the control unit 45 displays a printing screen G5 (see FIG. 7) on the touch panel 41.

If it is determined in step S44 that the candidate flag is NO (No), the control unit 45 skips steps S45 to S49 and proceeds to step S50. That is, if the candidate flag is NO, the control unit 45 immediately executes the print process (S50) without performing the main registration process or the process of selecting printing.

After the printing process (S50), the control unit 45 displays the post-login screen G4 (see FIG. 7) on the touch panel 41 (S51). If it is determined that NO is selected in step S49 (No), the control unit 45 displays the post-login screen G4 on the touch panel 41 without executing the print process (S51).

Further, if it is determined in step S43 that the data of the logged-in user is not registered in the temporary registration table TB2 (No), the control unit 45 skips steps S44 to S50 and displays the post-login screen G4 on the touch panel 41. (S51). After step S51, the control unit 45 returns to the main loop process (RETURN).

Next, a specific example of the operation of the control section 45 will be described. First, the operation of the control unit 45 when the first user whose user ID is "user_a" uses the printing device 4 will be described. Here, as shown in FIG. 2(a), the first user is a user whose email address is already registered in table TB1 in association with his/her user ID "user_a" and PIN code "1111". .

As shown in FIG. 1, when the first user sends an e-mail with an attached file with the file name "file1.pdf" from his terminal 2 to the printing device 4, the e-mail and the attached file are sent to the mail server. 3 is stored. The control unit 45 of the printing device 4 receives the e-mail and attached file sent by the first user by accessing the mail server 3 at predetermined intervals.

When the control unit 45 receives the first user's e-mail and attached file, it executes the e-mail analysis process shown in FIG. 4 . Since the first user's email address has already been registered in the table TB1, the control unit 45 determines Yes in the process of step S22 in the email analysis process. Thereafter, as shown in FIG. 2(b), the control unit 45 inputs the user ID "user_a" of the first user, the file name "file1.pdf" of the attached file attached to the first user's e-mail, and The candidate flag "NO" is stored in the temporary registration table TB2 (S24). Next, the control unit 45 stores the attached file attached to the first user's e-mail in the second storage unit 44B in association with the file name, user ID, etc. (S25).

As shown in FIG. 6, the control unit 45 displays a pre-login screen G1 on the touch panel 41 when no user has logged in. When the first user selects the user selection button B1 displayed in the characters "public" on the pre-login screen G1, the control unit 45 displays the user selection screen G2 on the touch panel 41.

Specifically, the control unit 45 displays a list of multiple user IDs stored in the table TB1 on the touch panel 41 on the user selection screen G2. The first user inputs the user ID "user_a" into the touch panel 41 by selecting his or her user ID "user_a" from the list displayed on the touch panel 41. Thereby, the control unit 45 determines that the user ID "user_a" in the table TB1 and the user ID "user_a" owned by the user match, and displays the PIN input screen G3 for inputting the PIN code on the touch panel 41. Display.

When the user inputs his or her PIN code "1111" on the PIN input screen G3, the control unit 45 converts the input PIN code "1111" into the PIN code "user_a" linked to the user ID "user_a" in the table TB1. 1111", and it is determined that the authentication is OK.

When the control unit 45 determines that the authentication is OK, the control unit 45 determines whether data related to the authenticated user ID "user_a" is registered in the temporary registration table TB2 (S43 in FIG. 5). If data related to the authenticated user ID "user_a" is not registered in the temporary registration table TB2, the control unit 45 displays the post-login screen G4 on the touch panel 41 (S43: No→S51).

If data related to the authenticated user ID "user_a" is registered in the temporary registration table TB2, the control unit 45 determines whether the candidate flag is YES (S44). Since the candidate flag corresponding to the first user is set to "NO", the control unit 45 determines No in step S44, and immediately executes the printing process (S50). In the printing process, the control unit 45 displays a printing screen G5 on the touch panel 41.

When the printing process is completed, the control unit 45 displays a post-login screen G4 on the touch panel 41. When the first user selects the user selection button B1 displayed as “user_a” on the post-login screen G4, the control unit 45 displays the logout selection screen G6 on the touch panel 41.

When the first user selects YES on the logout selection screen G6, the control unit 45 displays the pre-login screen G1 on the touch panel 41. When the first user selects NO on the logout selection screen G6, the control unit 45 displays a post-login screen G4 on the touch panel 41. Note that when there is no input to the touch panel 41 for a predetermined period of time with the post-login screen G4 displayed on the touch panel 41, the control unit 45 displays the pre-login screen G1 on the touch panel 41.

Next, the operation of the control unit 45 when the third user whose user ID is "user_c" uses the printing device 4 will be described. Here, as shown in FIG. 2(a), the third user is a user whose email address is not registered in the table TB1, and only the user ID "user_c" and the PIN code "3333" are linked to each other. This is a user registered in the table TB1.

As shown in FIG. 1, the third user inputs the third user's user ID "user_c" as the subject of an e-mail from his own terminal 2 to the printing device 4, and also inputs the file name "file3.pdf". When an e-mail with an attached file is sent, the e-mail and the attached file are stored in the mail server 3. The control unit 45 of the printing device 4 receives the e-mail and attached file sent by the third user by accessing the mail server 3 at predetermined intervals.

When the control unit 45 receives the third user's e-mail and attached file, it executes the e-mail analysis process shown in FIG. 4 . Here, since the third user's email address is not registered in the table TB1, the control unit 45 determines No in the process of step S22 in the email analysis process. Thereafter, in step S26, the control unit 45 determines that since the user ID "user_c" is input as the subject of the third user's e-mail, the subject of the third user's e-mail matches the user ID in table TB1. judge.

Thereafter, as shown in FIG. 2B, the control unit 45 selects the user ID "user_c" of the third user, the file name "file3.pdf" of the attached file attached to the third user's email, and the candidate The flag "YES" and the sender's e-mail address "user3@xxx.co.jp" are stored in the temporary registration table TB2 (S27). Next, the control unit 45 stores the attached file attached to the third user's e-mail in the second storage unit 44B in association with the file name, user ID, etc. (S25).

As shown in FIG. 7, when the third user selects his own user ID "user_c" on the user selection screen G2 and enters his own PIN code "3333" on the PIN input screen G3, the control unit 45 , it is determined that the authentication is OK. When the control unit 45 determines that the authentication is OK, the control unit 45 determines whether data related to the authenticated user ID "user_c" is registered in the temporary registration table TB2 (S43 in FIG. 5).

If data related to the authenticated user ID "user_c" is registered in the temporary registration table TB2, the control unit 45 determines whether the candidate flag is YES (S44). Since the candidate flag corresponding to the third user is set to "YES", the control unit 45 determines Yes in step S44, and displays the address registration screen G11 on the touch panel 41 (S45).

When the third user selects YES on the address registration screen G11, the control unit 45 executes the main registration process of registering the third user's e-mail address registered in the temporary registration table TB2 in the table TB1, and then A print selection screen G12 is displayed on the touch panel 41. When the third user selects NO on the address registration screen G11, the control unit 45 displays the print selection screen G12 on the touch panel 41 without executing the main registration process.

When the third user selects YES on the print selection screen G12, the control unit 45 displays the printing screen G5 on the touch panel 41 and executes the print process. When the third user selects NO on the print selection screen G12, the control unit 45 displays the post-login screen G4 on the touch panel 41 without executing the print process.

According to the above, the following effects can be obtained in this embodiment.
Since the user ID and PIN code are information that others do not know, by inputting the user ID and PIN code, it is possible to print the attached data of the e-mail linked to the user ID, making it possible to simply input the e-mail address. Security can be improved compared to other cases.

Even a user whose email address is not registered in the table TB1 can print attached data attached to an email simply by inputting the user ID in the subject of the email and sending the email.

Since the user is allowed to select whether or not to register the sender's e-mail address in the table TB1, the user can choose to register the sender's e-mail address in the table TB1 according to his/her will. For example, if a predetermined user borrows another person's computer and sends attached data to the printing device 4 using the other person's sender email address, the predetermined user selects not to register the other person's sender email address. can do.

Even if you do not register an e-mail address on the address registration screen G11, the print selection screen G12 will be displayed on the touch panel 41 after that, so you can, for example, send an attached file using an e-mail with an e-mail address that is not regularly used. In some cases, you can only print without registering an email address.
