Description

  The present invention selects an interrupt job display unit that displays another image forming job requested during execution of an image forming job as an interrupt job, and whether to execute the interrupt job displayed on the interrupt job display unit The present invention relates to an image forming apparatus that includes an interrupt job selection unit that performs an interrupt job when an interrupt job selection unit selects execution of the interrupt job.

  In general, when there is a request for another image forming job during execution of an image forming job, the image forming apparatus is registered in a waiting list in the order in which the image forming job is requested. Other image forming jobs are configured to be executed in the order registered in the list. However, even if you want to print quickly or if there is only one other image forming job, There is a problem that it is not easy to use because it is necessary to wait until the execution is completed.

Therefore, as shown in FIG. 10, when there is a print request from an external device during the execution of the copying sequence, the display means for displaying that fact and the interrupt printing by the displayed print request is permitted. A selection means for selecting whether or not based on an operator input, and when the permission of interrupt printing is selected by the selection means, the execution of the copy sequence is interrupted and the interrupt print sequence according to the print request is executed. In this case, an image forming apparatus that includes a sequence control unit that continuously executes the copying sequence when it is selected to be used in common with an external apparatus has been proposed.

  The above-described conventional image forming apparatus can be selectively executed by displaying that there is a request for another requested image forming job even during execution of the image forming job, thereby improving functionality. Is not considered when multiple other imaging jobs are required during the execution of an imaging job, but how to display an interrupt job and how to interrupt the job There was room for further improvement regarding whether or not to choose.

  For example, when multiple interrupt jobs are requested, it may be possible to display an interrupt job window on the touch panel display for generating and requesting acceptance of the interrupt jobs. When multiple interrupt job windows are displayed in parallel on the display screen, the number of display windows increases in response to an increase in the number of other required image forming jobs. Due to the limitation of the display area that displays the windows, There is a problem that it is difficult to display many windows.

  It is also conceivable to configure the interrupt job display means so that the window display area is reduced and displayed in parallel in response to an increase in the number of other image forming jobs required. Then, the display area of one window becomes too small, and there is a problem that it is difficult to display the window in a state where the operator can individually recognize it.

  In the present invention, in view of the above-described conventional technology, even when a plurality of other image forming jobs are requested during execution of the image forming job, the display area is not easily limited and can be individually recognized. Another object of the present invention is to provide an image forming apparatus capable of displaying another image forming job as an interrupt job in a window.

  In order to achieve the above object, a first characteristic configuration of the image forming apparatus according to the present invention is the other image requested during execution of the image forming job as described in claim 1 of the document of the claims. An interrupt job display means for displaying the forming job as an interrupt job in a window, an interrupt job selection means for selecting whether or not to execute the interrupt job displayed on the interrupt job display means, and an interrupt job selection means by the interrupt job selection means. An image forming apparatus comprising interrupt control means for executing the interrupt job when execution is selected, wherein the interrupt job display means includes a plurality of interrupt jobs requested during execution of the image forming job. The window display for the interrupt job is superimposed and displayed in an individually identifiable state, and the window display for the interrupt job is the top In the window that appears, in that it is configured to display the entire erase key to be operated cancel the interrupt job for all interrupt jobs windowed.

  According to the configuration described above, when a plurality of other image forming jobs are requested during execution of the image forming job, the window display can be individually identified by the interrupt job display unit as the other plurality of image forming jobs as the interrupt job. When the interrupt job selection means selects whether or not to execute the interrupt job displayed on the interrupt job display means and the interrupt job selection means selects execution of the interrupt job, the interrupt control means The interrupt job is executed. In other words, since the window display of the interrupt job is displayed in a superimposed manner, the same number and the same size of windows can be displayed in a small area as compared with the case where the above-mentioned window display is displayed in parallel, so the display area is limited. Even under such conditions, a plurality of interrupt jobs can be displayed in a window in a state that can be individually recognized by the operator. At this time, all interrupt jobs can be canceled simply by operating the delete key displayed in the window displayed on the top of the window display for interrupt jobs. In order to cancel multiple interrupt jobs individually This eliminates the need for complicated operations and improves convenience.

Furthermore, since the interrupt job with the highest priority is displayed on the top surface, the operator can easily recognize which interrupt job is the interrupt job with the highest priority.

  In the fourth feature configuration, as described in claim 4, in addition to any of the first to third feature configurations described above, the window displayed by the interrupt job display means displays each interrupt job individually. The task display unit displays identification information that can be identified, and a content display unit that displays detailed information of each image forming job, and at least the task display unit is superimposed and displayed in an individually identifiable state.

  According to the above-described configuration, among the windows superimposed on the task display unit, the task display unit is displayed in an individually identifiable state, so that the window corresponding to the interrupt job to be selected by the operator can be easily provided. Can be recognized.

  In the fifth feature configuration, as described in claim 5, in addition to any of the first to fourth feature configurations described above, the interrupt job display means selects any one of the superimposed windows. The selected interrupt job is displayed in the foreground when it is selected.

  According to the above configuration, when any of the superimposed windows is selected, the selected window is displayed in the foreground, so that the detailed contents of the interrupt job corresponding to the selected window can be easily obtained. It becomes possible to recognize, and the operability is further improved.

  In the sixth feature configuration, as described in claim 6, in addition to the fourth feature configuration described above, the interrupt job selection unit detects a selection key displayed on the content display unit and an operation on the selection key. The key operation detecting means is provided.

  According to the above configuration, when the operator performs a selection key operation to execute an interrupt job, the key operation detection unit detects an operation on the selection key, the interrupt control unit executes the interrupt job, and the operator interrupts When the selection key operation indicating that the job is not executed is performed, the operation for the selection key is detected by the key operation detection unit, and the interrupt job is not executed. That is, the operator can select whether or not to execute the interrupt job by operating the selection key.

  The seventh feature configuration is the same as that of the seventh aspect, in addition to the sixth feature configuration described above, the interrupt job display means responds when the operation of the selection key is detected by the key operation detection means. Is configured to close the window.

  According to the configuration described above, when the operator operates the selection key, the key operation detection unit detects an operation on the selection key, and the interrupt job display unit closes the corresponding window. In other words, windows that have been selected for whether or not to execute an interrupt job are closed, and only windows that are not selected for whether or not to execute an interrupt job are displayed, greatly reducing the complexity of subsequent operations on unselected windows. it can.

  In the eighth feature configuration, as described in claim 8, in addition to the sixth or seventh feature configuration described above, the interrupt job display means is configured to operate when the displayed window is not operated for a predetermined time. It is configured to close the corresponding window.

  According to the above-described configuration, the window is closed when an operation on the displayed window is not performed for a predetermined time. Therefore, it is not necessary to perform any operation on an image forming job that does not require execution of an interrupt job. Operation is simple.

  In the ninth feature configuration, as described in claim 9, in addition to any of the first to seventh feature configurations described above, the interrupt job display means has a predetermined number of superimposed windows. It is configured to close the window displayed first in response to the display of a new window.

  Hereinafter, an embodiment in which an image forming apparatus according to the present invention is employed in a digital multi-function peripheral will be described. As shown in FIG. 1, a digital multi-function peripheral 1 is connected to a network LAN to which a plurality of personal computers (hereinafter referred to as “PC”) are connected. The digital multi-functional peripheral 1 has a print function for executing a print job from a PC requested via the network LAN, a facsimile function for executing transmission / reception of image data with an external FAX (not shown) via a telephone line, A plurality of functions such as a copy function for copying a document are provided.

  As shown in FIG. 2, the digital multi-functional peripheral 1 displays a plurality of menu keys for setting a copy menu and the like, and starts a copying operation using a liquid crystal touch panel 20 for detecting an operation on each menu key or a set copy menu. An operation unit 2 on which a start key and the like are arranged, an image reading unit 4 that sequentially reads a series of documents set on the document placement unit 3 and converts them into electronic data, and is converted into electronic data by the image reading unit 4. Different in size or type from the electrophotographic image forming unit 5 that forms and outputs a toner image on a sheet based on image data transmitted from an external FAX, image data transmitted from an external FAX, image data transmitted from a PC, or the like Are provided with a plurality of paper feed cassettes 6 (6a to 6d) in which sheets of paper are stored and a manual paper feed port (not shown) provided on the left side of the machine. That.

  As shown in FIG. 3, in addition to the operation unit 2, the image reading unit 4, and the image forming unit 5, the digital multi-function peripheral 1 is a FAX modem for transmitting and receiving image data to and from an external FAX (not shown). 9, an external interface 10 for connecting to a plurality of PCs via a network LAN, and a control unit 8 for controlling them.

  The control unit 8 includes a microcomputer, a ROM in which a control program executed by the microcomputer is stored, and a peripheral circuit. The main function of the present invention embodied by the microcomputer is a functional block. When divided, as shown in FIG. 4, a job storage unit 80 that stores a plurality of requested image forming jobs in order of request, and the image forming unit 5 based on the jobs stored in the job storage unit 80. A job management unit 81 that requests the execution of each image forming job and manages other image forming jobs stored in the job storage unit 80 that are requested during the execution of the image forming job. Interrupt job identifying means 82 for identifying whether or not to be an interrupt target job, and the interrupt identified by the interrupt job identifying means 82 An interrupt job management unit 84 that manages the target job as an interrupt job, an interrupt job display unit 83 that displays the interrupt job managed by the interrupt job management unit 84 on the liquid crystal touch panel 20, and the interrupt job display unit 83. The interrupt job selecting unit 85 is configured to select whether or not the displayed interrupt job is permitted. The interrupt job managing unit 84 is selected when the interrupt job selecting unit 85 selects execution of the interrupt job. The job management unit 81 is requested to execute an interrupt job. That is, the interrupt job management means 84 and the job management means 81 constitute an interrupt control means for executing an interrupt job.

  In the job storage unit 80, job data relating to an image forming job requested from the PC, that is, the user name of the PC requesting the job, the request date and time, the paper size, the number of sheets, the image data, and the operation unit 2 Job data relating to image forming jobs and job data for fax data received via the telephone line are stored.

  The interrupt job identification unit 82 includes an interrupt job identification table for identifying whether or not the image forming job stored in the job storage unit 80 is an interrupt target job, and table data stored in the interrupt job identification table. Management of an image forming job determined to be an interrupt target job based on the above-described interrupt job management (part of job data capable of individually identifying an image forming job and interrupt priority data described later become management data) Delivered to means 81. When the interrupt job management means 81 displays the delivered interrupt job on the interrupt job display means 83 and recognizes an interrupt job selected to be executed by the operator via the interrupt job selection means 85, the interrupt job display means 83 An interrupt flag is set for the corresponding image forming job stored in the job storage unit 81.

  The job management means 81 executes and manages image formation processing for a plurality of image formation jobs stored in the job storage unit 81 in the order of request, and erases job data that has been executed. When the set image forming job is identified, the image forming job being executed is interrupted, and the image forming job with the interrupt flag set is preferentially executed and managed. The interrupt flag is composed of an interrupt counter indicating an interrupt priority. When the counter value is “0”, it indicates normal processing, and when the counter value is other than “0”, it indicates interrupt processing. Is set so that the higher the is, the higher the priority is. Therefore, for example, when an image forming job whose interrupt counter value is “1” occurs during the execution of the image forming job, the currently executing image forming job with the counter “0” is interrupted and the interrupt job is started. When an image forming job having an interrupt counter value “2” occurs during an interrupt job, the currently executing interrupt job is interrupted, and the image forming job corresponding to the interrupt counter value “2” is preferentially executed. . When the interrupt job ends, the previous interrupt job is resumed, and when the interrupt job ends, the interrupted initial image forming job is resumed so that multiple interrupt processing can be performed.

  The interrupt job identification table is set in advance by the administrator of the digital multi-function peripheral 1 or the like via the operation unit 2, and includes interrupt target job data and interrupt priority data for specifying an image forming job to be interrupted. Consists of. The job data to be interrupted includes a job corresponding to an interrupt key provided in the operation unit 2, a job requested from a PC, a job requested from a facsimile, a job for each functional unit such as copying, printing, and fax, and from a PC. In the case of a request job, the PC name or user name of the job request source, the file name of the image file, the number of sheets, the paper size, the paper type, and in the case of a request job from a facsimile, the job can be specified such as a caller telephone number Arbitrary data can be set, and three levels of interrupt priority data can be set for each interrupt target job data. Here, the interrupt priority order data is not limited to three stages, and may be configured to be set as appropriate. In the following embodiment, description will be made on the condition that interrupt target job data is set only for an image forming job from a network-connected PC.

  As shown in FIG. 5A, the liquid crystal touch panel 20 displays a menu screen for selecting basic copy menus such as the number of copies, paper size, copy magnification, output tray, sort, etc. While the job is running, [Copying. Is displayed.

  In the interrupt job identification table, when a user name in alphabetic combination is registered as the interrupt job data, and predetermined interrupt priority data is set for each user name, the interrupt job identification means 82 performs the job When an interrupt target job is identified from a plurality of jobs stored in the storage unit 80, the interrupt job display unit 83 causes the interrupt job display unit 83 to perform an instruction as shown in FIG. The interrupt job is displayed in the interrupt job window 200 as a window.

  The interrupt job window 200 includes a task display unit 201 that displays identification information that can individually identify the interrupt job, and a content display unit 202 that displays detailed information of each image forming job. The task display unit 201 displays an icon for identifying an interrupt job from a PC, identification information such as a user name “ABCDEFG”, and the content display unit 202 displays a file name and a request date and time of the image forming job. A selection key 204 of “Yes” or “No” for setting and inputting a part of job data such as a certain registration date and time and whether or not to execute the interrupt job is displayed.

  The task display unit 201 displays a minimizing key 203 (see FIG. 5B). When the minimizing key 203 is pressed by the operator, the interrupt job window 200 is deleted, and FIG. As shown in FIG. 5B, when the minimized display key 205 indicating that the display is minimized is displayed on the upper right portion of the liquid crystal touch panel 20, and the minimized display key 205 is operated in this state, The interrupt job display means 83 controls the display so that the interrupt job window 200 shown in FIG.

  The interrupt job selection means 85 includes the selection key 204 and a key operation detection means 86 for detecting any one of the selection keys 204. When the “Yes” key among the selection keys 204 is operated, the interrupt job selection means 85 is interrupted. When it is selected as a job and the “NO” key is operated, the interrupt job is canceled, that is, selected as a process in accordance with the normal request order, and the interrupt job management means 84 is notified accordingly. Thereafter, the interrupt job display means 83 closes the interrupt job window 200.

  When the interrupt job management unit 84 receives notification from the interrupt job selection unit 85 that execution of an interrupt job has been selected, the interrupt job management unit 84 stores the interrupt in job data for the image forming job stored in the job storage unit 80. A flag is set to notify the job management means 81 of the occurrence of an interrupt job. The job management means 81 executes and manages an interrupt job for job data for which an interrupt flag is set in the job storage unit 80 based on the notification.

  When there is a request for a plurality of other image forming jobs during execution of a normal image forming job or an interrupt job, and the interrupt job identifying unit 82 identifies these image forming jobs as interrupt jobs, the interrupt job display As shown in FIG. 6A, the means 83 superimposes and displays a plurality of interrupt print job windows 200 corresponding to these interrupt jobs in a state where the task display unit 201 can individually identify them.

  At this time, the interrupt job display means 83 superimposes a plurality of interrupt job windows 200 from the top to the back according to the requested interrupt job priority, that is, interrupt priority data, and when priority data is not set. Alternatively, when the priority order data is the same, the requested interrupt job is superimposed and displayed from the back to the top according to the request order.

  When the operator presses the second interrupt job window 210 on the plurality of interrupt job windows 200 shown in FIG. 6A, the interrupt job display unit 83 displays the interrupt job window 210 shown in FIG. 6B. As described above, the interrupt job window 210 that has been pressed is updated and displayed so as to be arranged in the foreground.

  Further, the interrupt job display means 83 is configured to display the all erase key 206 on the content display section 202 of the foremost interrupt job window 200. When the all erase key 206 is pressed, the liquid crystal touch panel is displayed. All the interrupt job windows 200 displayed at 20 are closed, and the interrupt job corresponding to the closed window is canceled, that is, selected as a process according to the normal request order.

  The interrupt job display means 83 further closes the window displayed on the back in response to the display of a new interrupt job window when the number of the interrupt job windows 200 displayed in a superimposed manner exceeds a predetermined number. When the operation for each displayed window is not performed for a predetermined time, the corresponding window is closed. As a result, it is possible to avoid displaying an unnecessarily large number of superimposed displays in the interrupt job window 200 where no interrupt job selection operation is performed. Here, when the number of superimposed windows exceeds a predetermined number, it is possible to close the window displayed first in response to the display of a new window.

  FIG. 7 shows an interrupt process when a print job as another image forming job is requested from the PC while a copying job which is one of the image forming jobs is being executed by the digital multi-function peripheral 1. It demonstrates based on the flowchart to show.

  When a previously requested image forming job is being executed (S1), when a print job is requested from the PC, the job management unit 81 stores job data in the job storage unit 80 (S2). Based on the received job data, the interrupt job identifying means 82 identifies whether the print job is an interrupt target job (S3). When the print job is not identified as an interrupt job, no interrupt processing is performed so that the print job is executed after the currently executing copy job is completed (S4). When the print job is identified as an interrupt job, The interrupt job display means 83 determines whether or not the interrupt job window 200 is displayed first (S5). When the interrupt job window 200 is not displayed first, the interrupt job window 200 corresponding to the print job is displayed. It is displayed (S6).

  When another interrupt job window 200 is already displayed, the priority order between the interrupt job displayed first and the current interrupt job is determined based on the priority data (S7). If the priority of the interrupt job currently requested from the PC is lower than the rank, the current interrupt job window 210 is superimposed on the back of the previous interrupt job window 200 so that the task display unit 201 does not overlap (S8). If the priority of the current interrupt job is higher than the priority of the previous interrupt job, the interrupt print job window 210 is displayed in front of the previous interrupt job window 200, that is, in the forefront so that the task display unit 201 does not overlap. The display is superimposed (S9).

  In this state, it is determined whether or not the currently displayed interrupt job window 200 meets the window deletion condition (S10). The window erasing condition is a condition for determining whether or not the all erasing key 206 is operated and whether or not the number of superimposed windows displayed exceeds a predetermined number, and is suitable for any window erasing condition. Sometimes the backmost window to be erased or the window displayed first (all interrupt windows when the all erase key 206 is pressed) is closed (S11), and an interrupt job corresponding to the closed window is displayed. Canceled (S12). That is, the interrupt flag is not set so that the canceled image forming job is executed after the currently executed image forming job is completed.

  If the window erasure condition is not met, it is further determined whether or not the interrupt job window 210 displayed on the back side has been pressed (S13). When the window is pressed, the interrupt job window 210 is positioned at the forefront. An updated display is displayed (S14).

  It is determined whether or not the selection key 204 of the interrupt job window 200 displayed in the foreground has been pressed (S15). If “No” of the selection key 204 is pressed (S16), the interrupt job window is closed. (S17) The interrupt job corresponding to the closed window is canceled (S18). When “Yes” on the selection key 204 is pressed, an interrupt flag is set for the interrupt job stored in the job storage unit 80 by the interrupt job management unit 84 and is currently executed by the job management unit 81. The image forming job in the middle is interrupted (S19), management control is performed so that the interrupt print job is executed (S20), and the interrupt print job window is closed (S21). The job management unit 81 resumes the interrupted image forming job after the interruption print job.

  When the current image forming job managed by the job management unit 81 is completed when the selection operation for the interrupt job window 200 displayed by the interrupt job display unit 83 is not performed, the job management unit 81 The other image forming jobs stored in the job storage unit 81 are executed and managed in the order of request. At this time, when the interrupt job displayed in the interrupt job window 200 is in the job execution order, the interrupt processing is performed. The interrupt job window is deleted based on an instruction from the job management unit 84.

  Another embodiment will be described below. In the above-described embodiment, the case where an interrupt process is performed when a print job is requested from the PC while the digital multi-function peripheral 1 is executing an image forming job has been described. The interrupt control according to the present invention can also be applied when there is a FAX reception, when an interrupt key is operated on the operation unit 2 during execution of an image forming job, or when they are mixed.

  For example, when interrupt control is performed for a FAX job, the transmission source user name or FAX number, the number of FAX jobs, etc. can be adopted as table data stored in the interrupt job identification table. Reception from a specific transmission source or reception with a small number of sheets can be set as an interrupt target job. Furthermore, it is possible to set so that reception in the memory reception mode and confidential reception are excluded from the interrupt job.

  As shown in FIG. 8A, in the interrupt job window 300 in this case, the task display unit 301 displays a company name (or name, telephone number, etc.) of the transmission source, an icon indicating a FAX job, and the like. Identification information is displayed, and “Yes” and “No” selection keys 304 for setting and inputting part of job data such as reception date and time, the number of output sheets, and whether or not to execute the interrupt job are displayed on the content display unit 302 The

  When a plurality of interrupt jobs are requested, as shown in FIG. 8B, the window display for the plurality of interrupt jobs is superimposed and displayed in an individually identifiable state, on the basis of the interrupt priority order and the request order. The display mode such as display is the same as described above.

  In the above-described embodiment, a description has been given of a case where a plurality of interrupt job windows are superimposed and displayed by the interrupt job display unit so that task display units that display identification information that can individually identify interrupt jobs do not overlap. As shown in FIG. 9, the window display for each interrupt job is displayed in a state where it can be individually identified. As shown in FIG. 9, identification information for individually identifying a plurality of interrupt job windows is displayed on a plurality of tabs. A method may be adopted. In this case, the tab is a task display unit, the display screen of the selected tab 207 is a content display unit, and control such as selection and deletion of each tab screen can be performed in the same manner as described above.

  In the above-described embodiment, the interrupt job identification unit is identified as whether or not the job is an interrupt job based on the interrupt job identification table including the interrupt target job data and the interrupt priority data, and the interrupt priority is identified. However, when the interrupt priority order is not set, it is possible to configure so that the interrupt jobs selected in the order of request of the image forming job are processed. When the interrupt target job data is not set, image forming is performed. All other image forming jobs requested during job execution can be configured to be identified as interrupt jobs.

  The display timing of the interrupt job window displayed by the interrupt job display unit 83 may be the timing when the interrupt job identifying unit identifies the interrupt job, but at that time, some operation is performed on the operation unit 2. The timing when no operation is performed for a predetermined time may be used. In the latter case, it is possible to solve the problem that the interrupt print job window is suddenly displayed during the operation of the operation unit and the other menu selection operations become difficult.

  In the above-described embodiment, a case where a plurality of print jobs are requested during execution of a copy job has been described. However, even when a plurality of other print jobs or copy jobs are requested during execution of a print job, a FAX is requested. The present invention can be applied even when a plurality of print jobs or FAX jobs are requested during job execution.

  Any of the above-described embodiments is merely an example of the present invention, and it is needless to say that the specific configuration and the like of each block can be appropriately changed and designed within the scope of the effects of the present invention.
