  The RAM 34 is a random access memory used as a work area for the main body control unit 32 as described above.

  The image forming unit 35 is for printing image data on paper (image formation) and outputting the printed paper on a tray (not shown) outside the apparatus.

  The HDD 36 is a hard disk device, and temporarily stores a print job received via the PCI / F unit 38 from each PC (personal computer) as another device of the print request source such as the PCs 100a, 100b, and 100c. In this case, the print job is grasped as a correspondence between the received image data relating to the print request and print job information attached to the image data, such as the number of pages of the image data and the user name. In this case, the print job information is not limited to the information notified at the time of the print request from the requesting PC 100a or the like, but is added as necessary in relation to the processing of the corresponding image data in the post-reception image forming apparatus 1. May be included.

  The HDD 36 stores each print job (combination of image data and print job information) received from the print request source PC such as the PC 100a, and also stores print order information that is information indicating the print order of each print job. is doing. The print order specified by the print order information is basically the time order of the print request, and the earlier the print request is made, the faster the process is performed. As will be described later, the print order is desired by the user. It is also possible to change according to the place.

  The clock circuit 37 always keeps track of the current date and time, and the main body control unit 32 reads the clock circuit 37 via the bus 40 to know the current date and time (date and time). it can.

The PC interface unit 38 receives a print request from the PC 100a and receives a print job. Specifically, the PC interface unit 38 is a general-purpose interface such as a LAN (local area network) interface or a USB (Universal Serial Bus). Is applicable.
The operation unit communication interface 39 is for exchanging information and data with the main body communication interface 28 on the operation unit 2 side.

  Each of the key groups 41 to 43 and 61 to 65 is a key that is “pressed” by selecting a corresponding position (touch operation) on the touch panel unit 26 that is superimposed on the liquid crystal display unit 27.

  The user makes a print request to the image forming apparatus 1 using the PCs 100a, 100b, 100c, and the like. Specifically, a print start operation is performed on document data created by a document data creation application (an image editing application, a word processor application, a spreadsheet application, etc.) running on the PC 100a or the like, and the print start operation is performed according to the print start operation. The document data application gives document data to a printer driver program running on the PC 100a or the like, the printer driver program converts the image data into image data suitable for the image forming apparatus 1, and the image data and accompanying information (print job) Information) is transmitted to the image forming apparatus 1 via the PC interface 38 as a print job related to the print request.

  In this case, the image data itself and the print job information such as the user name, the number of pages, the number of copies, and the like, which are included in the print job and associated with the print data, are stored in the HDD 36 as described above. is there.

  The main body control unit 32 sequentially processes each print job stored in the HDD 36 based on the print order information stored in the HDD 36. Specifically, the image system control unit 35 performs processing for printing on paper according to the output and outputting it outside the apparatus.

  On the other hand, when the job display / non-display switch key 24b is pressed on the operation unit 2, the operation control unit 21 requests the main body unit 3 to transfer print job information, image data, and print order information. The main body control unit 32 of the main body unit 3 outputs the print job information and image data from the HDD 36 to the print order information operation unit 2 in response to the request.

  The transferred print job information, image data, and printing order information are stored in the RAM 23 via the operation unit communication I / F 39 and the main body communication I / F 28.

  When the user selects (touch operation) the “thumbnail” display key 42, the operation control unit 21 reads out the print job information and image data stored in the RAM 23, and each image data for each print job. The first image is converted into a small image image (thumbnail) and expanded into a thumbnail display image in which multiple combinations of print job information (user name, job name, etc.) and a reduced image image are arranged, and a print job display area Thumbnail display 51 (displaying each thumbnail side by side) is performed.

  Further, when the user selects the “list” display key 43 (touch operation), only the print job information stored in the RAM 23 is read by the operation control unit 21 and a plurality of print jobs arranged in a list is displayed as a list display. The print job information list without an image is displayed in the print job display area 51.

  When the job display / non-display switch key 24b is pressed again on the operation unit 2, the print job information and image data stored in the RAM 23 are deleted, and the display on the liquid crystal display unit 27 is changed from the print job display to the current state of the apparatus. Return to the normal state that displays the operating state.

  FIG. 4 shows the print job display control processing procedure.

  In the figure, the operation control unit 21 responds to each print job from the HDD 36 of the main unit 3 when the “job display / non-display switching” key 24a is selected (touch operation) to display a print job (S101). The received print job information, image data, and print order information are received (S102). Note that the association between the print job information and the image data can be grasped as a print job as described above.

  Then, after receiving the print job information and the image data, the operation control unit 21 of the operation unit 2 reduces the first image data of each print job and converts the received print job into an image (S103). Then, the print job information and the reduced image are combined (associated), and a plurality of print jobs are displayed as thumbnails in the print job display area 51 (S104).

  Then, the selection (touch operation) of any of the “thumbnail” display key 42, the “preview” display key 41, and the “list” display key 43 is monitored (No in judgment S105, No in judgment S108, and judgment S112). No loop).

  When switching the display of the print job, when the “Preview” display key 41 is selected (touch operation) (Yes in S108), one of the thumbnail displays of each print job displayed in the print job display area 51 is displayed. Is determined to be explicitly (actively) selected (touch operation) (determination S109). If no explicit selection is made (No in determination S109), printing is currently being executed. The job information of the print job (specified by making an inquiry to the main body control unit 32) and the corresponding image data are previewed in the print job display area 51, and other thumbnails are displayed as a much larger image than in the case of thumbnail display. In addition to the single display (step S111), the process proceeds to step S114.

  If a print job is explicitly selected in the determination S109 (Yes in the determination S109), the selected print job and the corresponding image data are previewed in the print job display area 51, that is, thumbnails. As a much larger image than in the case of display, it is displayed as a single image, not with other thumbnails (step S111), and the process proceeds to step S114.

  As a result, the user can confirm the details of the desired print job in detail with the large-sized image data, and can surely confirm the current state of the job issued by the user in the image forming apparatus 1.

  When the “list” display key 43 is selected in the determination S112 (Yes in S112), a plurality of print job information items arranged in a list are displayed as a list display, that is, printing without an image image is performed in the print job display area 51. A job information list is displayed (processing S113), and the process proceeds to determination S114.

  If the “thumbnail” display key 42 is selected (touch operation) in the determination S105 when the print job is in the “preview” display state or “list” display state (Yes in S105), each print job is displayed. The first image data is converted into a reduced image (S106), the print job information and the reduced image are combined, a plurality of print jobs are displayed as thumbnails in the print job display area 51 (S107), and the process proceeds to S114. .

  Specifically, the thumbnail display in the process S107 is a display in the print job display area 51 of FIG. 3, and six of the seven print jobs currently pending in the image forming apparatus 1 (1/7 to 6/7), print job information (user name and job name) and thumbnail images are displayed in association with each other in the same frame. In addition, the print job “1/7” is a job that is currently being printed, and this fact is also displayed, so that it is possible to easily identify a print job that is currently being printed out of a large number of thumbnail-displayed print jobs. I can do it. Among the seven print jobs, those of “7/7” are switched and displayed by selecting (touching) the lower cursor key 70d in the lower right of the print job display area 51 in FIG. Select the upper cursor key 70u (touch operation) to return, or select the lower cursor key 70d (touch operation) and go round to return to the original (1/7 to 6/7) display. it can.

  In the determination S114, if the “job display / non-display switching” key 24a is not pressed (No in the determination S114), the process returns to the determination S105, but if pressed (Yes in the determination S114), the print job display area 51 is closed (the display is ended and the normal display is restored) (step S115).

  FIG. 5 shows a case where the “time display” key 62 is selected (touch operation) in the liquid crystal display unit 27 shown in FIG. Shows about.

  In FIG. 5, in the “time display” mode, the amount of print job information to be displayed for one print job is increased, so that thumbnail display for three cases is performed. However, it is possible to display thumbnails for all seven print jobs by switching the display by operating the upper right and lower cursor keys 70u, d.

  In the display of FIG. 5, when the “time display” key 62 is selected (touch operation) while the thumbnail display of the print job is displayed in the print job display area 51, the operation control unit 21 stores it in the RAM 23. The number of output sheets (number of pages of corresponding image data) and the number of output copies (number of print copies designated by the user who issued the job for the corresponding image data) are read from the print job information.

  Then, the operation control unit 21 knows the necessary print time for each size of image data in the image forming unit 35 and the number of output and the number of output copies of the image data related to each print job, which are known in advance and stored in the ROM 22. For each print job, the time required for print output (output time) is calculated, and based on the print order information stored in the RAM 23, the process of each print job is the process of each print job with the previous process order. The time (cumulative time) from when printing is started to when printing is completed is calculated, and additionally stored in the RAM 23 as part of print job information corresponding to each print job.

  Also in the display of FIG. 5, print job information including additional information of “number of output sheets (expressed by multiplying the number of copies per copy and the number of copies)”, “output time”, and “cumulative time” The thumbnail images are displayed in each frame in association with each other.

  FIG. 6 shows a “change order” key 3-3, a “time display” key 3-4, a “detailed content” key 3-5, which are performed by the operation control unit 21 in the thumbnail display state of FIG. A print job control processing procedure that is a procedure for controlling the case where each of the “Erase” key 3-6 and the “Print Cancel” key 3-7 is selected (touch operation) will be described.

  In FIG. 6, when the print job is displayed as a thumbnail in the print job display area 51 (S201), if the “time display” key 62 is not selected (touch operation) (No in determination S202), nothing is done. The process proceeds to step S204, but when a selection (touch operation) is made (Yes in determination S202), the number of output sheets and the number of output copies for each print job are read from the RAM 23 and specified by the number of output sheets and the number of output copies. The output time, which is the time required for image formation for the total number of printed sheets, is calculated, the calculation result is stored in the RAM 23, and information such as the output time is added to the thumbnail display displayed in the print job display area 51 (FIG. 5). Display state) (S203).

  The “time display” key 62 affects the display of all print jobs, but the “change order” key 61, “time display” key 62, “content details” key 63, and “erase” other than that. The key 64 and the “cancel print” key 65 affect only the specific print job selected.

A thumbnail is displayed in the area 51, and a change result is notified to the main body side and reflected in the “print order information” on the main body side (rewrite change) is performed (step S206), and the process proceeds to judgment S214.

  When the “erase” key 64 is selected (Yes in determination S207), the job deletion process, that is, the specified print job among the print jobs stored in the RAM 23 is deleted and displayed in the print job display area 51. The print job information and the image are deleted from the displayed thumbnail display, and the deletion result is notified to the main body and reflected in the print job management on the main body (deletion change) is performed (processing S208). The process proceeds to determination S214.

  When the “detailed content” key 63 is selected (Yes in determination S209), the detailed job content thumbnail display process, that is, all information and all image data of the designated print job among the print jobs stored in the RAM 23 are displayed. A process of displaying the print job information of the specified print job in the read and print job display area 51 and displaying the image data of each page as a thumbnail is performed (process S210), and the process proceeds to determination S214.

  When the “print cancel” key 65 is selected (Yes in determination S211), job output cancel processing, that is, print cancel information is added to the print job stored in the RAM 23 and specified in the print job display area 51. In addition, information about print cancellation is additionally displayed in the print job that has been issued, and further, an image output stop request for the designated print job is issued to the main body unit 22, the next print job is executed, and processing is performed (step S212). The process proceeds to S214.

  In the determination S214, when the “thumbnail” display key 42 is not selected (touch operation) (No in the determination S214), the process ends. When the “thumbnail” display key 42 is selected (Yes in the determination S214), the process S201 is performed. Return to.
