JP 2001-216123 A

  Although it is preferable from the viewpoint of ensuring security that printing processing is not performed until user authentication is performed as described above, for example, when a large number of confidential document print jobs are submitted from the PC or the like After user authentication is performed on the image forming apparatus side, a print instruction for each job must be given, which impairs convenience.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus capable of improving user convenience while ensuring security.

  In order to solve the above-described problems, a first image forming apparatus according to the present invention is an image forming apparatus capable of receiving a job from an external apparatus and performing a printing process. Storage means capable of storing, standby time information acquisition means for acquiring information related to job execution standby time, elapsed time measurement means for measuring elapsed time since the job was accepted, and authentication means for performing user authentication If the user corresponding to the received job performs user authentication before the execution waiting time elapses, the print control unit that executes print processing according to the job, and the execution without performing user authentication. And a job storage unit for storing print target data of the job in the storage unit when the standby time has elapsed.

  In the configuration of the present invention, when user authentication is executed before the execution waiting time elapses, print processing is executed even if no print instruction is issued. Thereby, it is possible to cope with printing of a document having confidentiality, and convenience is improved.

  The storage means may have a user box area assigned to a user, and the job storage means may store print target data in a user box area assigned to a user corresponding to the job.

  When a user corresponding to the job performs user authentication after the execution waiting time has elapsed, an unprinted job notifying unit for notifying that an unprinted job is stored in the user box area is provided. It can also be configured.

  The storage means has a public box area accessible to all users, and the job storage means stores data to be printed in the public box area when the user corresponding to the job is not registered for authentication. It can also be configured to store.

  The information related to the execution standby time is set in the job, and the standby time information acquisition unit acquires the information related to the execution standby time from the job. In this case, for example, the execution waiting time can be specified by a printer driver installed in an external apparatus that inputs a job.

  The execution waiting time may be configured to be set to a different value depending on the type of job. Examples of job types include a print job and a file transmission job.

  The second image forming apparatus according to the present invention performs predetermined information exchange by communicating with other image forming apparatuses in advance, and configures a virtual subnetwork in which each image forming apparatus and a user identifier are associated with each other. Information about the job execution waiting time when a job is submitted, a virtual subnetwork configuration unit that performs storage, a storage unit that can store data to be printed, a job detection unit that detects job submission Standby time information acquisition means for acquiring the time, elapsed time measurement means for measuring the elapsed time since the job was received, and authentication detection means for detecting that user authentication has been performed in any of the plurality of image forming apparatuses If the user who submitted the job performs user authentication before the execution waiting time elapses, any of the plurality of image forming apparatuses is selected according to the job. And print control means for controlling to perform the print processing or, if the execution waiting time has elapsed is characterized by comprising a job storage means for storing print data of the job in the storage unit.

  The execution waiting time may be set to a different value when the user authentication is performed by the image forming apparatus assigned to the user who has submitted the print job and when the user authentication is performed by another image forming apparatus. It can be configured.

  When the user authentication is performed on the image forming apparatus assigned to the user who has submitted the print job, the print control unit executes a printing process on the image forming apparatus and performs user authentication on the other image forming apparatus. In the case where the process is performed, the job data may be transmitted to the other image forming apparatus. In this case, the printing process is executed by another image forming apparatus.

  When the user authentication is detected after the execution elapsed time has elapsed, the image forming apparatus that has performed the user authentication is controlled to notify that the unprinted job is stored in the storage unit. An unprinted job notification control unit may be provided.

  According to the image forming apparatus of the present invention, for example, it is possible to improve convenience while ensuring security when printing a confidential document.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
(1) Configuration of Print System FIG. 1 is a diagram illustrating an example of the overall configuration of a print system according to the present embodiment. The print system is configured by connecting an MFP (multifunction peripheral) 100 and a PC (personal computer) 31 via a LAN (local area network) 500.

  A printer driver is installed in the PC 31 and instructs the MFP 100 to print. When printing is instructed by the printer driver, a print job is input to the MFP 100. MFP 100 is an example of an image forming apparatus to which a job is input. The MFP 100 is an image forming apparatus that integrates functions such as copying, network printing, a scanner, a FAX, or a document server. Sometimes called a multifunction device. The LAN 500 is an example of a connection form between a PC and an image forming apparatus, and may be wired or wireless. Note that the number of PCs and image forming apparatuses connected to the LAN 500 is arbitrary.

  In the printer driver of this embodiment, designation of job execution standby time can be input. FIG. 2 is a diagram illustrating an example of a window displayed on the display of the PC 31 when the PC 31 instructs printing. In the figure, when the check box 311 is not checked, a print job similar to the conventional one is input (the MFP 100 may have an execution standby time set).

  When the check box 311 is checked, an execution waiting time can be specified in the box 312. The “execution standby time” in the present embodiment is a standby time for performing print processing when the user performs authentication in MFP 100 before the execution standby time elapses. After the execution waiting time elapses, the printing process is not performed only by the user authenticating with the MFP 100.

(2) Configuration of MFP 100 FIG. 3 is a diagram illustrating an example of a hardware configuration of MFP 100. FIG. 4 is a diagram illustrating an example of the appearance of the MFP 100. As illustrated in FIG. 3, the MFP 100 includes an operation unit 11, a display unit 12, a scanner unit 13, a printer unit 14, a communication interface 16, a document feeder 17, a paper feeding device 18, a CPU 20, a ROM 21, a RAM 22, and a hard disk 23. Consists of.

  The operation unit 11 includes a plurality of keys for inputting numbers, characters, symbols, and the like, a sensor for recognizing the pressed key, and a transmission circuit for transmitting a signal indicating the recognized key to the CPU 20. .

  Display unit 12 displays a screen for displaying a message to the user, a screen for the user to input setting content and processing content, a screen showing a result of processing executed by MFP 100, and the like. In the present embodiment, a touch panel is used for the display unit 12, which is included in the operation unit 11. The touch panel has a function of detecting the position on the touch panel touched by the user with a finger and transmitting a signal indicating the detection result to the CPU 20.

  The scanner unit 13 irradiates the original with light and detects reflected light, thereby reading an image drawn on the original and generating digital image data (here, density data representing RGB or black density). To do. The image data obtained in this way is used for printing in the printer unit 14 and is converted into a file in a format such as TIFF, PDF, JPEG, etc., and stored in the hard disk 23. It may be converted into FAX data and used for FAX transmission. The document feeder 17 is provided on the upper part of the main body of the MFP 100 and is used to sequentially send one or more originals to the scanner unit 13.

  The printer unit 14 receives an image read by the scanner unit 13, an image of data transmitted from an external device such as a PC (personal computer) 31 connected via a network such as the LAN 500, or a FAX received FAX. Print an image of the data on a recording sheet such as paper or film. The paper feeding device 18 is provided in the lower part of the MFP 100 main body, and is used to supply a recording sheet suitable for an image to be printed to the printer unit 14. The recording sheet on which the image is printed by the printer unit 14 is discharged to the tray 19 (see FIG. 4).

  The communication interface 16 is a device for communicating with an external device such as a PC via a network or performing FAX transmission / reception via a telephone line. As the communication interface 16, a NIC (network interface card), a modem, a TA (terminal adapter), or the like is used.

  The ROM 21 stores programs and data for realizing basic functions of the MFP 100 such as image reading (scanning), document copying (copying), FAX data transmission / reception, network printing, and a document server (box function). ing. In addition, programs and data for realizing the functions of the present embodiment are stored.

  Some or all of these programs or data may be installed in the hard disk 23. In this case, the program or data installed in the hard disk 23 is loaded into the RAM 22 as necessary. Note that the functions described in the present embodiment may be realized not only by the CPU 20 but also by using dedicated hardware such as a DSP (digital signal processor) or ASIC (specific application IC). Further, it may be realized by using a function of a general-purpose program such as an operating system (OS).

  FIG. 5 is a diagram for explaining the box of the present embodiment. The box can be provided on the hard disk 23, for example, for each user. In the example of the figure, user boxes 231A and 231B provided for each user, and a public box 231P accessible to anyone are shown. In principle, the user box 231A or the like cannot be accessed unless the user assigned the box logs in through user authentication.

(3) Processing Contents of MFP 100 Hereinafter, processing contents of MFP 100 as an example of an image forming apparatus will be described. The following processing is realized by, for example, a program stored in the ROM 21 operating on the CPU 20. FIG. 6 is a flowchart for explaining an example of processing contents in the present embodiment.

  In the present embodiment, when MFP 100 accepts a print job (S101: YES), measurement of elapsed time after accepting the print job is started (S102). Then, it is determined whether or not the user is registered as a user who may log in to MFP 100 through authentication (S103). This determination can be made with reference to, for example, a user registration table (a table for managing authentication information such as a user ID and a password) managed in the MFP 100.

  If the user is a registered user (S103: YES), before the time set as the execution standby time has elapsed (S105: NO), if the user logs in through user authentication (S104: YES), print The job is executed (S106). Here, the print job is executed even if the login user does not give a print instruction.

  On the other hand, if the execution standby time has elapsed before the user authentication is executed (S105: YES), the print job is stored in the user box (S107). Here, the print job is stored in the user box of the user who submitted the print job.

  As a result of the processing as described above, when the user who has submitted a print job from the PC 31 performs user authentication with the MFP 100 within the set execution standby time, a print result can be obtained quickly, while execution standby There is an advantage that when the time elapses, the capacity of the RAM 22 is not occupied for a long time by the print job.

  Note that, when user authentication is performed, whether or not a print job is stored in the user box of the user is referred to, and if an unprinted print job is stored, the fact is notified. it can. This notification can be performed, for example, by displaying a message on the display unit 12.

  Note that if the user is not a registered user in step S103 (S103: NO), it can be determined that the user (guest user) does not log in through user authentication. The fact that the job has been submitted is displayed (S108). For example, it may be possible to display a message from a guest user other than the registered user that a print job with an execution waiting time set has been submitted.

  Then, the process proceeds to the flowchart of FIG. 7, and when a print instruction is given via the operation unit 11 or the like (S109: YES) before the execution standby time elapses (S111: NO), the print job is executed (S109: YES). S110). The printing instruction here can be instructed by all users other than the user who submitted the print job.

  If the set time has passed without a print instruction (S109: NO, S111: YES), the processing setting preset in the MFP 100 is referred to (S112). In the present embodiment, the process setting that can be set here is “print” or “box save”, and if the process setting is “print” (S113: YES), the print job is executed (S114). . If the processing setting is not “print” (S113: NO), the print job is stored in the public box 231P (S115).

  As for the fact that the print job is stored in the public box 231P, for example, a message to that effect may be displayed on the display unit 12 or a button indicating that may be displayed. For example, a button 121 as shown in FIG. 8 is displayed on the display unit 12, and when the button 121 is pressed, a list of jobs stored in the public box 231P can be displayed. The user can select any one of the displayed print jobs and execute the printing process.

  In the above-described embodiment, the execution waiting time is set when a print job is submitted. However, the execution waiting time may be set in advance on the MFP 100 side, and the execution waiting time may be set. However, if the execution standby time is set when a print job is submitted from the PC 31, the setting on the PC 31 may be prioritized. The execution waiting time once set by the printer driver on the PC 31 side is stored as an initial setting in the PC 31 so that the stored value is automatically set at the next printing. it can.

(Modification of Embodiment 1)
In the above embodiment, a print job has been described as an example of a job. However, as a job type, there is a file transmission job that transmits a file by designating a destination user, for example, in addition to a print job. Furthermore, there is a case in which a setting is made so that print processing is automatically executed when a file transmission job is submitted. The present invention can be applied not only when a print job is input as in the above embodiment, but also when a file transmission job is input.

  FIG. 9 is a diagram showing an example of the contents of the execution standby time management table held in the MFP 100 in this case. The transmission destination user is the transmission destination user of the file transmission job, and the print job execution standby time indicates the setting of the execution standby time when the transmission destination user submits the print job as in the above embodiment.

  The file processing setting specifies the processing to be executed for the transmitted file when the file is transmitted to the destination user by the file transmission job. In addition to printing, the file content is faxed or attached to an e-mail. It is also possible to set transmission, storage in a box, and the like. The file transmission job execution standby time indicates the setting of the execution standby time when printing is set as the processing setting.

  In this modification, when a file transmission job is submitted, the printing process is not executed immediately, and the printing process is not executed until the time set as the file transmission job execution standby time elapses. Then, before the time set as the file transmission job execution standby time elapses, the print processing is executed when the destination user logs in through authentication.

  On the other hand, when the time set as the file transmission job execution waiting time has elapsed, the file transmitted to the user box of the transmission destination user is stored. When user authentication is executed after the elapse of time, it can be notified that the file transmitted by the file transmission job is stored in the user box.

  In this modification, it is possible to set different values for the execution standby time for the print job and the file transmission job. By doing so, for example, the execution standby time when the user submits a print job and the execution standby time when a file is transmitted from another person can be changed, and the convenience is further improved.

(Embodiment 2)
Next, a second embodiment of the present invention will be described. In the present embodiment, an embodiment of the present invention when a virtual sub-network is configured between a plurality of MFPs will be described.

(4) Configuration of Virtual Subnetwork System FIG. 10 is a diagram for describing the configuration of the virtual subnetwork 501 in the embodiment of the present invention. In the example shown in the figure, MFPs 100, 100 A, 100 B, and 100 C are connected to a network 500.

  In this embodiment, the group names set in MFP 100, MFP 100A, and MFP 100B are the same, and virtual sub-network 501 is configured by these three MFPs. MFP 100 </ b> C has a different set group name and is not an MFP constituting virtual sub-network 501. When configuring the virtual sub-network 501, for example, group names can be exchanged using broadcast packets, and the virtual sub-network can be configured with image processing apparatuses in the same group.

  Note that the number of MFPs constituting the virtual sub-network 501 is arbitrary. Regarding the configuration method of the virtual sub-network, the contents of other patent applications (for example, Japanese Patent Application No. 2005-160999, Japanese Patent Application No. 2005-161000, Japanese Patent Application No. 2005-161001, and Japanese Patent Application No. 2005-236931) by the applicant of the present application are also referred to. I want.

  In virtual sub-network 501 in the present embodiment, users who mainly use MFP 100, 100A, and 100B are preset. Therefore, each of MFPs 100, 100A, and 100B stores registered user information for registering users who are mainly used. The registered user information will be described later, but includes at least a user identifier for identifying the user.

  In the present embodiment, the MFP in which the registered user information of the user is stored is referred to as “home terminal”. For example, if registered user information of user “David” is stored in MFP 100, the home terminal of user “David” is MFP 100. Note that the registered user information is stored in each of MFPs 100, 100A, and 100B in order to improve operability by preliminarily defining users to be used in advance, and for registered users who do not store registered user information. Use is not prohibited.

  Here, it is assumed that MFP 100A and 100B are already connected to network 500 and virtual sub-network 501 is configured, and MFP 100 is newly connected to network 500. The MFP 100 needs to be set with apparatus identification information for identifying the MFP 100 and the above-described registered user information. When device identification information and registered user information are set in MFP 100, MFP 100 transmits the device identification information and registered user information to other MFPs 100A and 100B. Thereby, the virtual sub-network 501 is constructed in the MFPs 100, 100A, 100B.

  Hereinafter, specific processing contents when the virtual sub-network 501 is constructed will be described using the MFP 100 as an example. FIG. 11 is a flowchart for explaining the processing contents of the newly connected MFP 100 and other MFPs.

  Prior to the construction of the virtual sub-network 501, terminal information is first registered in the MFP 100 (S201). The terminal information includes device identification information for identifying MFP 100 and a group name. The device identification information is preferably location information in the network 500 assigned to the MFP 100, and for example, an IP address can be used.

  Next, registered user information of a user who uses MFP 100 as a home terminal is input to MFP 100 (S202). When a plurality of users use MFP 100 as a home terminal, registered user information of each of the plurality of users is input.

  The registered user information includes a user identifier for identifying the user. The user identifier may be unique information for each user, such as a user ID consisting of characters or symbols, a user name, and the user name is used as the user identifier in the present embodiment. The registered user information includes personal information for each user in addition to the user identifier.

  The user personal information is information related to the user and includes, for example, accompanying information, address book, panel setting information, authentication information, and history information. When the virtual sub-network 501 is configured, these user personal information allows the user to log in in the form of accessing the virtual sub-network 501 and operate other MFPs in the same manner as the home terminal. Used to improve.

  The terminal information and the registered user information are input by the operation of the operation unit 11 by the user. Specifically, an input screen for terminal information and an input screen for registered user information are displayed on the display unit 12, and the user operates the operation unit 11 according to these screens to input terminal information and registered user information. The terminal information is normally registered by the terminal manager, whereas the registered user information is usually input by the user.

  Thereafter, it is determined whether or not the initial setting in MFP 100 has been completed (S203). If the initial setting has not been completed, the process returns to step S201. If the initial setting has been completed (S203: YES), the group name is transmitted by broadcast to other terminals than MFP 100 (S204).

  When the other terminal connected to the network 500 such as the MFP 100A receives the group name transmitted from the MFP 100 (S301: YES), it is determined whether or not the group name is the same as the group name set in the own device. If it is the same group (S302: YES), the terminal information set in the own device and the registered user information are transmitted to the MFP 100 (S303). Since MFP 100C has a different group name, it does not transmit its own terminal information or the like to MFP 100. In this way, the virtual sub-network 501 is constructed between terminals having the same group name.

  On the MFP 100 side, information transmitted from the same group of terminals (MFP 100A, MFP 100B) is received (S205), and user data is generated (S206). Then, the terminal information registered in the MFP 100 and the registered user information in the initial setting are transmitted (S207). When the other terminal (MFP 100A, MFP 100B) receives the terminal information and registered user information transmitted from MFP 100 (S304: YES), it generates and adds user data (S305).

  In this embodiment, user data respectively generated in MFP 100 and other terminals is a collection of terminal information and user identification information of MFPs 100, 100A, and 100B, and includes terminal information and user identifiers for each terminal. . User data generated in each MFP is stored in the hard disk. Through the above processing, the same user data is stored in MFPs 100, 100A, and 100B.

  FIG. 12 is a diagram for describing registered user information. 12A is a diagram showing an example of registered user information registered in MFP 100, and FIG. 12B is a diagram showing an example of registered user information registered in MFP 100A. FIG. 12C illustrates an example of registered user information registered in the MFP 100B. FIG. 13 is a diagram illustrating an example of user data.

  The registered user information according to the present embodiment includes a number, a user identifier, and user personal information. The user personal information includes accompanying information, an address book, panel setting information, authentication information, and history information. The accompanying information is information unique to each user, such as a department name to which the user belongs, an e-mail address assigned to the user, face image data obtained by photographing the user's face, and the like.

  The address book is information in which destination information registered and transmitted by the user is collected, and includes, for example, a user identifier, an e-mail address, a facsimile number, and the like of the destination user. An initial setting of the transmission method for each registered user (for example, designation of whether the transmission method as the initial setting is an e-mail or a FAX transmission) may be included.

  The panel setting information is screen information customized by the user. The authentication information is information used for user authentication at the time of login to the virtual sub-network 501, and here, a password is used. In MFP 100 and the like according to the present embodiment, login when using virtual sub-network 501 and login to the MFP alone can be performed separately, and authentication information used for login to virtual sub-network 501 is as follows. The password used when logging into the MFP alone is managed separately.

  The history information is data generated in the MFPs 100, 100A, 100B when the user instructs the MFPs 100, 100A, 100B to execute processing, and includes the contents of the instructions. The content of the instruction includes, for example, an e-mail transmission, a transmission destination, and a transmission content if the instruction is an e-mail transmission processing instruction. Note that the user data shown in FIG. 13 includes a number, a user identifier, and device identification information of the home terminal.

  As described above, the same user data is generated and stored in MFPs 100, 100A, and 100B to which the same group name is set. Thereby, a virtual sub-network 501 composed of MFPs 100, 100A, and 100B is formed. When the virtual sub-network 501 is formed, a user who uses any one of the MFPs 100, 100A, and 100B as a home terminal can be specified based on the user data. Therefore, a user other than the home terminal can be selected using the user data. When the user operates, the user personal information recorded in the home terminal can be taken into the terminal.

(5) Processing for Job Submission in Virtual Subnetwork 501 Hereinafter, an embodiment to which the present invention is applied when the virtual subnetwork 501 as described above is constructed will be described. When the virtual sub-network 501 is constructed, for example, the group name and user are specified when a print job is submitted.

  As described in the modification of the first embodiment, when a virtual sub-network 501 is constructed, a processing method when a job (for example, a file transmission job) is submitted for each user is set in advance. You can also. FIG. 14 is a diagram illustrating an example of a table for setting a job processing method and an execution standby time defined in the present embodiment. This information can be included in the user personal information shown in FIGS. 12 and 13, for example.

  As shown in FIG. 14, in the present embodiment, the execution waiting time can be set separately for the case where the user logs in through authentication at the home terminal and the case where the user logs in through authentication at another terminal. . For example, when the user “David” is designated and a print job is submitted, the data of the submitted print job is first transmitted to the MFP 100 that is the home terminal of the user “David”.

  On the other hand, the user “David” can not only log in through user authentication in MFP 100 that is the home terminal, but can also log in through authentication in MFPs 100A and 100B that are other terminals. This is because the authentication information is shared by each MFP as shown in FIG.

  In the state in which the virtual sub-network 501 is established, when the user “David” logs in through authentication with the MFP 100A, for example, the home terminal of the user “David” is the MFP 100, and therefore, the user “David” is input. The MFP 100A can easily recognize that there is a possibility that the job data stored in the MFP 100 may be stored.

  Therefore, for example, when the user “David” performs user authentication on the MFP 100A, it is possible to easily transfer the data of the input print job from the home terminal (MFP 100) to the MFP 100A and execute the printing process on the MFP 100A. . As shown in FIG. 14, the execution standby time is changed depending on whether the authentication is performed at the home terminal or the authentication at another terminal in consideration of the time required to move to another terminal. This is because it is possible to improve the convenience. Therefore, an embodiment in which the execution standby time is set for each MFP configuring the virtual sub-network is possible.

  In the case of a file input job, if the processing setting is “print” like the users “David” and “Julie” shown in FIG. 14, it is executed separately as in the modified example of the first embodiment. A waiting time can be set. Also in this case, the execution standby time can be changed between when authenticating at the home terminal and when authenticating at another terminal.

  FIG. 15 is a flowchart for explaining an example of the processing contents of the present embodiment. The process shown in FIG. 6 can be executed when a job input to the user is detected at each home terminal (S401: YES).

  The home terminal starts measuring the elapsed time after accepting the job input (S402). If the execution standby time has passed without any user authentication in any MFP configuring the virtual sub-network 501 (S403: NO, S404: YES), the job data is stored in the user box (S405). In this embodiment, it is assumed that the user box is assigned to the hard disk of the home terminal. The execution elapsed time in step S404 is the longest time among the various execution elapsed times set as shown in FIG.

  When user authentication is detected (S403: YES), when user authentication is executed at the home terminal (S406: YES), a print job is executed at the home terminal (S407). When the user authentication is executed by another terminal (S406: NO), the job data is transmitted to the MFP for which the user authentication has been executed (S407). As a premise, when user authentication is executed by another terminal, the home terminal is notified of that. By executing the print job on another MFP that has received the job data, the user can obtain a print result at a place other than the home terminal.

  Note that although a plurality of execution standby times are set as shown in FIG. 14, illustration in the flowchart is omitted, but after the determination in step S <b> 406, an elapsed time until user authentication is set. It is also possible to compare the execution standby time and execute the print job or send the job when the execution standby time is within the set execution standby time.

  Further, when an unprinted job whose execution standby time has elapsed is stored in the user box, the fact that the unprinted job is stored on the display unit of the MFP that has performed user authentication at the time when the user authentication is performed is displayed. Can be displayed. In this case, for example, a button 121 as illustrated in FIG. 8 can be displayed to display a stored job list (job list data may be transmitted from the home terminal).

(Modification of Embodiment 2)
In the above embodiment, a case has been described in which MFPs that make up the virtual sub-network 501 are all connected to the same LAN 500, but the virtual sub-network is between MFPs connected to a plurality of LANs having different network addresses. It is also possible to configure. For example, it is possible to make the same group between MFPs connected via a WAN (wide area network). For example, when logging in through user authentication on an MFP at a business trip destination, An embodiment in which data is acquired and print processing is executed is also possible.

  The present invention can be applied to an image forming apparatus such as an MFP.
