Next, the operations of the multifunction device B and the terminal device D in the storage medium management system A having the above configuration will be described in detail with reference to the sequence diagrams of FIGS. 4 and 5. 4 and 5 are sequence diagrams showing the operations of the multifunction device B and the terminal device D of the storage medium management system A according to the present embodiment. First, a user who wants to print an electronic file stored in the USB memory C by the multifunction device B attaches the USB C to the USB port 11 of the multifunction device B.

Then, the user selects an electronic file to be printed from the electronic files stored in the USB memory C by operating the operation screen displayed on the touch panel 10a or / and the operation keys of the operation display unit 10, and the operation display unit By pressing the 10 state keys, the selected electronic file is printed on the multifunction device B. Then, the CPU 1 of the multifunction device B reads the electronic file to be printed from the USB memory C via the USB port 11, and causes each part such as the image forming unit 8 to execute the printing operation based on the electronic file.

After the print operation is completed, the CPU1 determines whether or not the USB memory C has been removed from the USB port 11 (step S1), and if it determines "YES" in step S1, that is, the USB memory C from the USB port 11. If is removed, the operation display unit 10 waits until it receives a print instruction. When the CPU1 determines "NO" in step S1, that is, when the USB memory C is still attached to the USB port 11, the CPU1 has completed the printing operation within a predetermined time. It is determined whether or not the operation display unit 10 has accepted the data operation instruction of the USB memory C (step S2). The data operation instruction in step S2 is an operation instruction in which the CPU 1 executes the writing of the electronic file, the reading of the electronic file, and the erasing of the electronic file to the USB memory C. That is, the data operation instruction also includes the print instruction received by the operation display unit 10 by pressing the start key.

When the CPU1 determines "YES" in step S2, that is, when the operation display unit 10 receives the data operation instruction of the USB memory C within a predetermined time from the end of the print operation, the operation display is displayed. Wait until the unit 10 accepts the print instruction. If the CPU 1 determines "NO" in step S2, that is, if the operation display unit 10 does not accept the data operation instruction of the USB memory C within a predetermined time after the print operation is completed, the USB memory C Create a forgotten notification email to notify that the USB memory C has been forgotten while using the email address of the terminal device D registered in the e-mail address registration file stored in the file as the destination (step S3). ..

Specifically, in step S3 above, the CPU 1 reads an e-mail address from the e-mail address registration file stored in the USB memory C via the USB port 11 and sets the e-mail address as the e-mail destination. Further, by setting a message in the body and subject of the e-mail notifying that the USB memory C stored in ROM2 has been forgotten, a forgotten e-mail is created. After step S3, CPU1 causes terminal device D to send a missed-take notification mail to communication I / F section 9 (step S4). In step S3, CPU1 puts the serial number read from the USB memory C in the forgotten notification mail.

When the terminal device D receives the forgotten notification mail from the multifunction device B, the forgotten notification mail is displayed on the display (step S5), and when the reply mail creation instruction is given by the keyboard or the mouse, the sender of the forgotten notification mail is sent. Create a reply e-mail with the serial number of USB memory C included in the forgotten notification e-mail as the destination to the e-mail address of the multifunction device B (step S6), and attach the reply e-mail transmission instruction. The reply mail is sent to the multifunction device B (step S7).

When the communication I / F section 9 receives the reply mail from the terminal device D, the CPU 1 of the multifunction device B matches the serial number of the USB memory C attached to the USB port 11 with the serial number in the reply mail. If it is determined whether or not (step S8) and "YES" is determined in step S8, that is, if the serial number of the USB memory C installed in the USB port matches the serial number in the reply mail. To erase all electronic files stored in the USB memory C installed in the USB port 11 (step S9).

Then, after step S9, the CPU1 uses the e-mail address of the terminal device D, which is the source of the reply mail, as the destination, and notifies that the electronic file stored in the USB memory C has been successfully erased. An e-mail is created (step S10), and the erasure success notification e-mail is sent to the terminal device D to the communication I / F section 9 (step S11). In step S10, the CPU 1 puts the USB memory operation history information corresponding to the serial number in the reply mail in the erasure success notification mail based on the USB memory operation history information table.

For example, if the serial number of the USB memory C is included in the reply mail from the terminal device D and the serial number of the USB memory C is "A6400", the USB of the USB memory operation history information table shown in FIG. The USB memory operation history information of the memory operation history information numbers "0001" to "0005" is put in the erasure success notification mail.

If the CPU1 determines "NO" in step S8, that is, the USB memory C is not installed in the USB port 11, or the serial number of the USB memory C installed in the USB port and the reply mail are listed. If the serial numbers do not match, the electronic file stored in the USB memory C is set as the destination and the electronic file stored in the USB memory C is set as the destination without erasing the electronic file in the USB memory C. An erasure failure notification e-mail for notifying that the file erasure has failed is created (step S12), and the erasure failure notification e-mail is transmitted to the terminal device D via the communication I / F section 9 in step S11.

Further, in step S12, the CPU 1 puts the USB memory operation history information corresponding to the serial number in the reply mail in the erasure failure notification mail based on the USB memory operation history information table in the same way as in step S10. When the terminal device D receives the erasure success notification mail or the erasure failure notification mail from the multifunction device B in the above step S11, the terminal device D displays the erasure success notification mail or the erasure failure notification mail on the display (step S13).

As described above, in the storage medium management system A according to the present embodiment, the operation is performed within a predetermined time after the printing operation is completed with the USB memory C still attached to the USB port 11. If the display unit 10 does not accept the data operation instruction of the USB memory C, it is determined that the USB has been forgotten, and the e-mail address of the terminal device D registered in the e-mail address registration file stored in the USB memory C. Is set as the destination, and a forgotten notification mail for notifying that the USB memory C has been forgotten is created, and the forgotten notification mail is sent to the terminal device D to the communication I / F section 9.

With the conventional method of notifying the forgetting to remove the USB memory C by sounding a warning sound and displaying a warning screen, the notification could not be recognized when the user leaves. By notifying the user of forgetting to remove the USB memory C by e-mail, the user can recognize the forgetting to remove the USB memory C by e-mail, so that the user is away from the multifunction device B. Can also recognize forgetting to remove the USB memory C. In this way, by sending a forgotten email from the multifunction device B to the user, it is possible to prevent the USB memory C from being forgotten, that is, by strengthening the prevention of leakage of the information stored in the USB memory C, the information is more than before. Security can be improved.

In addition, when CPU1 of the multifunction device B receives the reply mail of the forget-to-take notification mail, if the serial number in the reply mail matches the serial number of the USB memory C, the electronic file stored in the USB memory C is sent to the user. Since it is judged that there is an intention to erase and the electronic file of the USB memory C is erased, even if the user is in a place where the USB memory C cannot be immediately removed from the multifunction device B, the USB can be operated immediately by remote operation. By being able to erase the electronic file in the memory C, the prevention of leakage of the information stored in the USB memory C is strengthened, so that the information security can be further improved.

Further, the CPU 1 of the multifunction device B causes the terminal device D to send an erasure success notification mail or an erasure failure notification mail to the communication I / F unit 9 depending on the success or failure of erasing the electronic file stored in the USB memory C, and further, this By posting the USB memory operation history information of the USB memory C in the erasure success notification mail or the erasure failure notification mail, the user can tell that the USB memory C has been operated by a third party as well as the success or failure of erasing the electronic file of the USB memory C. Since it can be known immediately, it is possible to immediately deal with the leakage of the information stored in the USB memory C.
