Interruption management method for an image forming apparatus
A user-interface unit receives a request from a user. A control unit performs an execution control in response to the request received by the user-interface unit, and during an execution process, performs an interruption process and an authentication process. An application-logic unit provides a plurality of functions related to an image forming process. A device-service unit provides a shared service for the application-logic unit.
1. An image forming apparatus configured to perform a plurality of functions related to an image forming process, the image forming apparatus comprising:
a user-interface unit configured to receive a request from a user;
a control unit configured to control an execution process in response to the request received by the user-interface unit, wherein during the execution process, the control unit is configured to process an interruption process and a related authentication process;
an application-logic unit configured to perform, based on the execution process of the control unit, at least one of the functions related to the image forming process; and
a device-service unit configured to provide a shared service for the application-logic unit.
2. The image forming apparatus according to claim 1 , wherein the control unit includes
a session management unit configured to perform, during a session from a login to a logout of the user, the authentication process, and to perform a user authentication by associating a user and a session identified at the authentication process; and
a request management unit configured to perform, when a session provided by the session management unit is valid, an execution control of the request from the user.
3. The image forming apparatus according to claim 2 , wherein the session management unit is configured to request the authentication process when performing an interruption.
4. The image forming apparatus according to claim 3 , wherein the session management unit is configured to determine whether to perform the interruption based on information indicating a user level.
5. The image forming apparatus according to claim 2 , wherein the session management unit is configured to display a lock screen at an end of an interruption, to request a user authentication, and to return to an operation screen when the authentication process succeeds.
6. The image forming apparatus according to claim 3 , wherein the session management unit is configured to pass a password check in the authentication process, when the user-interface unit receives an interruption request from a login user.
7. The image forming apparatus according to claim 2 , wherein
the session management unit is configured to display an authentication screen at an end of an interruption, when there is a session of a login user, to display an operation screen corresponding to the session, when there is no session of the login user, to determine that an interruption occurs, and then to create a new session and display an operation screen corresponding to the new session.
8. The image forming apparatus according to claim 7 , wherein the session management unit is configured to pass the authentication process, when there is the session of the login user and a job is being executed in a returned session, and when there is an interruption by the user.
9. The image forming apparatus according to claim 7 , wherein the session management unit displays is configured to display an operation screen corresponding to a latest session when there is a plurality of sessions of the login user.
10. The image forming apparatus according to claim 7 , wherein the session management unit is configured to display an operation screen of a latest session without performing the authentication process, after a current user ends an interruption, if at least one session of the user is left.
11. The image forming apparatus according to claim 7 , wherein the session management unit is configured to display the operation screen on which a username of a current user, a number of login users, and an icon indicating that an interruption process is running, while suspending other jobs.
12. The image forming apparatus according to claim 3 , wherein the session management unit is configured to pass a password check in the authentication process since a second time interruption request, when there are a series of interruption requests from an identical user.
13. The image forming apparatus according to claim 12 , wherein the session management unit is configured to pass a password check in the authentication process, when there is a second interruption request from an identical user within a predetermined time after a first interruption process is finished.
14. The image forming apparatus according to claim 5 , wherein the session management unit is configured to skip a lock-screen display at an end of an interruption since a second time of interruption request, when there is a second interruption request from an identical user.
15. The image forming apparatus according to claim 5 , wherein the session management unit is configured to allow a setting of displaying the lock screen at the end of the interruption.
16. The image forming apparatus according to claim 15 , wherein the session management unit is configured to allow the setting of displaying the lock screen by a lock key on each interruption job.
17. The image forming apparatus according to claim 1 , wherein the authentication process includes a combination of a presentation of a noncontact integrated-circuit card and an input of a password.
18. The image forming apparatus according to claim 2 , wherein
the authentication process includes a combination of a presentation of a contact-type integrated-circuit card and an input of a password, and
the session management unit is configured to display a lock screen when the contact-type integrated circuit is removed.
19. A method of managing an interruption in an image forming apparatus having a plurality of functions related to an image forming process, the method comprising:
receiving, by a user-interface unit, a request from a user;
controlling, by a control unit, an execution process in response to the request received in the receiving step, and during the execution process, performing an interruption process and a related authentication process;
performing, by an application-logic unit, based on the execution process of the control unit, at least one of the functions related to the image forming process; and
providing a shared service for the application-logic unit.
20. A non-transitory computer-readable medium having computer-readable program codes embodied in the medium that, when executed, cause a computer to execute:
receiving, by a user-interface unit, a request from a user;
controlling, by a control unit, an execution process in response to the request received in the receiving step, and during the execution process, performing an interruption process and a related authentication process;
performing, by an application-logic unit, based on the execution of the control unit, at least one of the functions related to the image forming process; and
providing a shared service for the application-logic unit.
