The display control unit 42 controls the display screen 18 to display the first password input screen or the second password input screen. The password input screen switching control unit 43 controls to switch between the display of the first password input screen and the display of the second password input screen according to a predetermined condition. The determination unit 44 matches the password input via the operation unit 13 when the first password input screen is displayed by the display control unit 42 and the first password registered by the password registration receiving unit 41. Determine whether or not. The determination unit 44 matches the password input via the operation unit 13 when the second password input screen is displayed by the display control unit 42 and the second password registered by the password registration receiving unit 41. Determine whether or not. If the determination unit 44 determines that the passwords match, the reception permission unit 45 permits reception of a request from the user regarding image formation by the image forming unit 15.

  First, registration of the first password will be described. FIG. 5 is a diagram showing an example of a first password registration screen displayed when registering the first password.

  With reference to FIG. 5, a first password registration screen 51 for accepting password registration by the password registration acceptance unit 41 is displayed on the display screen 18 by the display control unit 42. The first password registration screen 51 includes a notation 52 of “password registration screen”, a password input unit 53 for inputting the first password to be registered, and a password re-input unit 54 for re-inputting the first password to be registered. And “OK”, and a selection key 55 for confirming the input when pressed. The user registers the first password from the first password registration screen 51.

  FIG. 6 is a flowchart showing a typical processing flow when registering the first password. With reference to FIGS. 5 and 6, the display control unit 42 displays the first password registration screen 51 described above on the display screen 18 in response to a user request input via the operation unit 13 (in FIG. 6). Step S11, hereinafter, “step” is omitted). Thereafter, the user inputs a first password to be registered corresponding to the first password input screen to the password input unit 53. Then, the user inputs the input first password to the password re-input unit 54 again for confirmation. Thereafter, the user presses the selection key 55 to confirm the input. When the pressing of the selection key 55 is detected, the password registration receiving unit 41 receives the input of the first password and the re-input of the first password (S12). Then, it is determined whether or not the input first password matches the re-input first password (S13). If it is determined that the input first password matches the re-entered first password (YES in S13), password registration receiving unit 41 registers the input first password (S14). . In this case, the password registration receiving unit 41 stores the input first password data in the hard disk 16 in association with the first password input screen.

  On the other hand, if it is determined that the input first password does not match the re-input first password (NO in S13), the fact that the first password does not match, specifically, for example, “ For example, the display control unit 42 indicates that the passwords do not match, and that the user is prompted to re-enter the first password, specifically, for example, “Please register your password again.” (S15). Then, the input of the first password is accepted again (S12). In this way, the first password is registered by the password registration receiving unit 41. Here, it is assumed that the numerical value “1234” is registered as the first password.

  The registration of the second password corresponding to the second password input screen is similarly performed. FIG. 7 is a diagram illustrating an example of a second password registration screen displayed when registering the second password. Note that this second password registration screen is displayed by the display control unit 42 in response to a request from the user via the operation unit 13 by shifting from the first password registration screen 51 shown in FIG.

  Referring to FIG. 7, the second password registration screen 56 includes a notation 57 of “password registration screen (second)”, a password input unit 58 for inputting a second password to be registered, and a first password registration screen 56. A password re-input unit 59 for re-inputting the second password and a selection key 60 which is written as “OK” and confirms the input when pressed are shown. In this case, the user can easily recognize from the notation 57 that the second password registration screen 56 is displayed.

  Then, similarly to the registration of the first password, the second password is registered along the flow shown in FIG. In this case, the registered second password is different from the first password. That is, the password registration receiving unit 41 rejects if the same password as the first password is to be registered. In this way, the second password is registered. Here, it is assumed that the numerical value “5678” is registered as the second password.

  Next, a password input screen serving as a login screen for authenticating the password input by the user will be described. FIG. 8 is a diagram illustrating an example of a password input screen. Referring to FIG. 8, on password input screen 61, notation 62 of “login screen” notifying that it is a login screen, password input unit 63 for inputting a password, and “clear” are displayed. The display control unit 42 displays a selection key 64 for clearing the password input by pressing and a selection key 65 for displaying the password input by pressing and displayed on the display screen 18. Yes. The user inputs a password on the password input screen 61 using the numeric keypad 31 or the like.

  The password input screen 61 is the same screen for the first password input screen and the second password input screen. That is, the displayed items and contents are exactly the same on the first password input screen and the second password input screen, and are visually indistinguishable.

  Next, a case where the user makes a print request to the multifunction machine 11 using the printer function of the multifunction machine 11 will be described. FIG. 9 is a flowchart showing the flow of processing when a print request is made to the multifunction device 11.

  Referring to FIGS. 1 to 9, using any of computers 26 a to 26 c connected to network 25, the user sends a request for printing, that is, forms an image, to image transmission to multifunction device 11. Make a request. Then, the control unit 12 receives a print request from any of the computers 26a to 26c connected to the network 25 (S21).

  Thereafter, the control unit 12 determines whether or not a plurality of print jobs are accumulated in the multifunction machine 11 (S22). That is, it is determined whether a plurality of jobs to be printed are accumulated. If it is determined that a plurality of print jobs are accumulated (YES in S22), password input screen switching control unit 43 switches between displaying the first password input screen and displaying the second password input screen. Control as follows. Specifically, the password input screen switching control unit 43 controls to switch from displaying the first password input screen to displaying the second password input screen. In this case, the predetermined condition is a condition in which a plurality of image formation requests to the image forming unit 15 are received. That is, the display control unit 42 controls to display the second password input screen (S23).

  In this case, since the display of the second password input screen and the display of the first password input screen are the same, the user does not notice that the second password input screen is displayed. Here, after the second password input screen is displayed, the user first inputs the first password “1234” into the password input unit 63. Then, the control unit 12 receives an input of the first password “1234” (S24). Then, the determination unit 44 determines whether or not the input first password “1234” matches the second password “5678” registered in the second password input screen (S25).

  In this case, since the first password “1234” is input on the second password input screen, the passwords do not match (NO in S25), and authentication fails. Then, a message indicating that the authentication has failed and prompting the user to input the password again is displayed (S26).

  Here, the user notices that the second password input screen is displayed, and inputs the registered second password “5678” to the password input unit 63. Then, the control unit 12 receives an input of the second password “5678” (S24). Then, the determination unit 44 determines whether or not the input second password “5678” matches the second password “5678” registered on the second password input screen (S25).

  In this case, since the second password “5678” is input on the second password input screen, the passwords match (YES in S25), and the authentication is successful. In other words, if the determination unit 44 determines that the passwords match, the reception permission unit 45 permits reception of a request from the user regarding image formation by the image forming unit 15 (S27). In this case, a display screen for requesting output is displayed on the display screen 18. Thereafter, printing is executed based on the input by the user. Here, when authentication is successful, a setting that is permitted only to the logged-in user, for example, a setting for full-color printing is performed in response to a user request and output.

  Thereafter, whether the acceptance permission by the acceptance permission unit 45 is due to the coincidence of the first password or the coincidence of the second password is stored in the hard disk 16 as the storage unit (S28). In this case, the second password is stored as a match. Then, the process ends.

  On the other hand, if it is determined that a plurality of print jobs are not accumulated (NO in S22), display control unit 42 displays the first password entry screen as it is on display screen 18 (S29). Thereafter, the user inputs the first password “1234” into the password input unit 63. In this case, since authentication is successful (YES in S25), permitted printing is set and output.

  According to such a multifunction machine 11, the password input screen switching control unit 43 switches between the first password input screen and the second password input screen displayed by the display control unit 42. Then, it is determined whether or not the passwords match according to each password input screen, and if they match, it is determined that the login authentication has succeeded, and the request is accepted. Then, for example, when the second password entry screen is displayed and the second password is entered, even if the second password is stolen by a malicious third party staying in the vicinity of the multifunction device 11, In one password input screen, the passwords do not match due to the input of the second password. Therefore, security at the time of user authentication can be improved.

  In this case, since the first password input screen and the second password input screen are the same, even if a malicious third party views the password input screen 61, the difference is not known. Therefore, the level of security can be further increased.

  In this case, since the second password input screen is switched under the condition that a plurality of image formation requests that are likely to be in the vicinity of the multifunction peripheral 11 are received, the security level is more reliably set. Can be increased.

  In the above embodiment, the case where a print request is made from the computers 26a to 26c to the multifunction device 11 has been described. However, the present invention is not limited to this, and the case where the user visits the multifunction device 11 to perform copying. Applied.

  FIG. 10 is a flowchart showing the flow of processing when the user uses the copy function of the multifunction device 11 and makes a copy by visiting the multifunction device 11. Referring to FIG. 10, the user goes to a place where the multifunction machine 11 is installed. Then, when copying, user authentication is performed.

  When a copy request is received from the user (S31), a first password input screen is first displayed on the display screen 18 by the display control unit 42 (S32). Here, when there are many people around, the user switches from the first password input screen to the second password input screen. In this case, a predetermined gesture for switching from the first password input screen to the second password input screen is input to the operation unit 13.

  Then, password input screen switching control unit 43 detects that there is a request for switching the password input screen (YES in S33), and switches to the second password input screen. That is, the password input screen switching control unit 43 controls to switch from the display of the first password input screen to the display of the second password input screen when detecting an input of a predetermined gesture to the operation unit 13. . Then, the display control unit 42 displays a second password input screen on the display screen 18 (S34).

  Thereafter, an input of a password is accepted (S35), and if the input second password matches (YES in S36), the authentication is successful. Then, acceptance of a request from the user regarding image formation by the image forming unit 15 is permitted (S37). In this case, copying is performed by setting permitted copying. If there is no request for switching the password input screen in S33 (NO in S33), the first password input screen is displayed as it is for authentication.

  According to such a configuration, the password input screen can be switched according to a user request. Accordingly, it is possible to ensure security according to the needs of the user.

  In the above embodiment, if the password input screen switching control unit 43 detects a predetermined gesture in the input to the operation unit 13, it displays the first password input screen and the second password input. However, the present invention is not limited to this. For example, a switching key for switching between the display of the first password input screen and the display of the second password input screen is provided. If pressing is detected, it may be controlled to switch between the display of the first password input screen and the display of the second password input screen. Further, if a predetermined gesture is input, control may be performed so that a switching key is displayed on the touch panel.

  In the above embodiment, the display control unit 42 displays the first password entry screen next when the hard disk 16 stores that the permission of acceptance is due to the coincidence of the second password. You may control. By doing so, even if the second password is stolen, the input of the second password on the first password input screen results in an authentication failure, so that the security level can be further increased.

  Furthermore, if it is stored in the hard disk 16 that the acceptance is due to the coincidence of the second password, the display control unit 42 prohibits the display of the second password input screen until a predetermined period elapses. It may be. By doing so, a malicious third party who steals the second password cannot switch to the second password input screen and input the second password. Therefore, the security level can be further increased. In this case, there is no problem because a user who has set and registered the first and second passwords can successfully authenticate with the first password.

  Furthermore, if it is stored in the hard disk 16 that the permission to accept is due to the coincidence of the second password, the display control unit 42 is input by the operation unit 13 when the first password input screen is displayed. You may comprise so that a display of a 2nd password input screen may be prohibited until a password and the 1st password registered by the password registration reception part 41 correspond. By doing so, it is possible to prevent the successful authentication of a malicious third party who knows only the second password, and to further increase the security level.

  In the above embodiment, the display of the first password input screen and the display of the second password input screen may be displayed differently. By doing so, the user can easily recognize which password input screen is displayed, and the convenience of the user can be further improved. Specifically, the display content is not changed, and the font and size of the characters in the typeface, the display arrangement, and the like may be changed.
