When the login button 316 (see FIG. 4) is pressed at this stage, the screen moves to the screen of FIG. 5B, and the multi-function peripheral 101 waits for input of authentication information. When the user B inputs authentication information and touches the execution button on the screen of FIG. 5B, the screen moves to the screen of FIG. 5C. As a result, the user B has logged into the multifunction machine 101.

  On the screen of FIG. 5C, “Login user: User B” is displayed. This means that the user B who is logged in to the multifunction machine 101 occupies the screen of the operation panel of the multifunction machine 101. At this stage, it is assumed that the copy job of user A is being executed. When the copy job of user A is completed, the screen moves to the screen of FIG. 5D. “Can copy” is displayed on the screen of FIG. 5D. This means that user B's copy job can be executed. When the logout button 317 (see FIG. 4) is pressed at this stage, the screen moves to the screen shown in FIG. 5E, and the multi-function peripheral 101 waits for input of authentication information. As a result, user B has logged out of the multi-function peripheral 101.

  In the “login process” from FIG. 5A to FIG. 5C, the MFP 101 in FIG. 1 maintains the login of “user A” who logs in to the MFP 101 and occupies the operation panel screen of the MFP 101. In this state, “User B” is newly logged into the MFP 101, and “User B” is made to occupy the screen of the operation panel of the MFP 101. Thereby, parallel use (multiple login) of user A and user B is realized, and it is possible to allow user B to prepare for job start while continuing user A's job.

  In the “logout process” from FIG. 5C to FIG. 5E, the MFP 101 of FIG. 1 maintains the login of “user A” who does not occupy the operation panel screen of the MFP 101 after logging in to the MFP 101.

In response, a copy job start request is transmitted from the copy application 141 to the ECS 164 (S103). In response to this, the copy job of the user A is started, and the reading process of the copy original set in the ADF 321 (FIG. 3) is successively executed (S104).

  Subsequently, when the user B presses the login button 316 to log in to the multifunction machine 101, the OCS 166 notifies the SCS 169 that the login button 316 has been pressed (S111). In response to this, the SCS 169 notifies the CCS 167 that the login button 316 has been pressed (S112). In response to this, the CCS 167 executes simultaneous arbitration of the back transition of the user A (S113), and if the back transition of the user A is OK (S114), the CCS 167 executes the simultaneous distribution of the back transition of the user A (S115). ) Subsequently, the authentication condition is notified from the CCS 167 to the copy application 141 (S116). In response to this, a request for displaying an authentication information input waiting screen is transmitted from the copy application 141 to the CCS 167 (S117). In response to this, the CCS 167 transmits an authentication information input waiting screen display request to the SCS 169 (S118). In response to this, a request to display an authentication information input waiting screen is transmitted from the SCS 169 to the OCS 166 (S119). In response, an authentication information input waiting screen (FIG. 5B) is displayed, and the multi-function peripheral 101 enters an authentication information input waiting state.

  Subsequently, when the user B inputs authentication information and presses the execution button, the OCS 166 notifies the SCS 169 that the execution button has been pressed (S121). In response, the SCS 169 notifies the CCS 167 that the execution button has been pressed (S122). In response, the CCS 167 requests the UCS 168 to confirm the existence of the user “user B” related to the authentication information (S123), and confirms the existence confirmation of the user “user B” related to the authentication information is OK (S124). If there is, simultaneous distribution of the ticket of the user “user B” related to the authentication information is executed (S125). Subsequently, a display request for a copy operation screen without the guidance “Can copy” is transmitted from the copy application 141 to the OCS 166 (S126). Subsequently, a request for canceling the display of the authentication information input waiting screen is transmitted from the copy application 141 to the CCS 167 (S127). In response to this, a request to cancel the display of the authentication information input waiting screen is transmitted from the CCS 167 to the SCS 169 (S128). In response to this, a request for canceling the display of the authentication information input waiting screen is transmitted from the SCS 169 to the OCS 166 (S129).
