  The parallel job storage unit 7 stores data indicating the names of other jobs that can be executed in parallel with a predetermined job being executed. For example, if “out of paper” occurs during execution of a “copy” job or during execution of a “copy” job, other jobs that can be executed in parallel include “confirm filing data”, “Scan” “To Email”, “FAX transmission”, “Email address registration”, “copy reservation setting”, and the like, and data indicating these names are stored in the parallel job storage unit 7. Based on the image data stored in the parallel job storage unit 7, the display control unit 49 displays the names of other jobs that can be executed in parallel with the job being executed on the display unit 82.

  The image display device 8 displays information to be notified to the user, such as the operating state of the digital copying machine 1, the image related to the job, the preview image of the read image, the confirmation of the operation content of the operation device 10, etc. A display unit 82 including a display is provided. In addition, the image display device 8 includes a sensor unit 81 that detects the touch coordinates by detecting the contact of the fingertip of the user with the touch panel provided with the display unit 82. The display unit 82 displays soft keys for accepting job execution instructions such as “fax”, “copy”, “print”, “mail”, “read”, and the like. By touching the screen (touch panel) of the display unit 82 corresponding to the soft key, a job execution instruction related to the soft key is received.

  The sensor unit 81 is a so-called touch sensor that can detect multi-touch. Touch sensor methods include a capacitive type, a matrix resistive membrane type, and other transparent types that are attached to a liquid crystal display device, an electromagnetic induction type (multiple coils are placed on the display surface, and a pen There is a sensor liquid crystal system in which a sensor is embedded in the liquid crystal itself, and the like, and any of them may be used.

  Therefore, a predetermined designation can be received from the user via the sensor unit 81. For example, when the user's fingertip touches a predetermined position on the touch panel of the display unit 82, the control unit 2 acquires a signal from the sensor unit 81, and the touch coordinates where the user's fingertip and the touch panel are in contact based on the signal. And an instruction to execute a soft key related to the specified coordinates is received. Transmission and reception between the control unit 2 and the sensor unit 81 at this time will be described in detail below.

  FIG. 4 is a graph showing transmission / reception between the control unit 2 and the sensor unit 81 in the digital multi-function peripheral 1 according to Embodiment 1 of the present invention. In the following, for convenience of explanation, a case where a single touch is detected will be described as an example. In the following description, the case where the H level is in the interrupt state and the I2C bus is used will be described as an example.

First, when detecting a user's touch, the sensor unit 81 outputs an interrupt signal (H level) to the control unit 2 through the bus N. When detecting the interrupt signal, the control unit 2 reads the touch coordinates in the following procedure (see FIG. 4A).
(1) The control unit 2 asserts the START signal. (Fall data signal)
(2) The control unit 2 starts clock output.
(3) The control unit 2 outputs an address unique to the sensor unit 81.
(4) After recognizing the address, the sensor unit 81 asserts ACK (acknowledge signal) and deasserts the interrupt signal. (L level output)
(5) The sensor unit 81 outputs the number touched (number of points). (Here 1)
(6) The control unit 2 asserts ACK.
(7) The sensor unit 81 outputs coordinates in the X (lateral) direction among the touched coordinates.
(8) The control unit 2 asserts ACK.
(9) The sensor unit 81 outputs coordinates in the Y (vertical) direction among the touched coordinates.
(10) The control unit 2 asserts ACK.
(11) The control unit 2 stops the clock output.
(12) The control unit 2 asserts the STOP signal. (Launch data signal)
Thereby, the control unit 2 can obtain the touch coordinates on the sensor unit 81.

  If a plurality of touches (for example, two points) are detected, the sensor unit 81 outputs “2” in the above (5). Further, the second coordinate is output from the sensor unit 81 following the first coordinate (see FIG. 4B). Furthermore, when the touch is continuously performed, the sensor unit 81 does not deassert the interrupt signal in the above (4), so that the control unit 2 reads the coordinates as shown in FIG. Do it continuously.

  Hereinafter, execution of a plurality of jobs in the digital multi-function peripheral 1 according to the first embodiment of the present invention will be described in detail. For convenience of explanation, an instruction to execute “copy” is received from the first user, and “out of paper” has occurred while the first processing system is executing a “copy” job. A case will be described as an example in which an instruction to execute “preview of filing data” is received and the second processing system executes a job of “preview of filing data”. FIG. 5 is a flowchart showing a processing procedure by the control unit 2 of the digital multi-functional peripheral 1 according to the first embodiment of the present invention.

  For example, when the first user places a plurality of documents on an automatic document feeder (not shown) of the image input device 3 and touches the “copy” soft key of the display unit 82, the CPU 21 detects the sensor unit. By acquiring touch coordinates from 81 using the method described above, an instruction to execute “copy” is accepted (step S101).

  Next, for example, the first user touches a soft key on the display unit 82 to set the number of copies, an enlargement ratio, and the like, and the CPU 21 receives the setting instruction via the sensor unit 81 (step S102). The CPU 21 stores data related to the accepted setting in the RAM 23.

  For example, the CPU 21 checks whether the document is normally placed, whether the paper is out, whether the paper is jammed, and the like, and determines whether or not the document is in a normal state (step S103). Such a determination is made, for example, when the CPU 21 acquires a signal from a sensor of the automatic document feeder, a sensor of a paper cassette, or the like.

  If the CPU 21 determines that it is in a normal state (step S103: YES), it instructs the image input apparatus 3 to read the original and executes a copy job (step S104).

  The image processing device 4 performs image processing on the image data read by the image input device 3, and the image output device 5 forms an image based on the image data image-processed by the image processing device 4 on a sheet and outputs it. To do. Thereafter, the CPU 21 determines whether or not the “copy” job is completed based on the setting relating to “copy” stored in the RAM 23 (step S105).

  When the CPU 21 determines that the “copy” job has ended (step S105: YES), the CPU 21 ends the process. On the other hand, when it is determined that the “copy” job has not ended (step S105: NO), the CPU 21 returns the process to step S103 and determines again whether or not the job is in the normal state.

  On the other hand, if the CPU 21 determines in step S103 that the state is not normal (step S103: NO), the CPU 21 notifies the first user that a trouble has occurred (step S106). Specifically, the CPU 21 displays on the display unit 82 an image for notifying the location of the trouble, the content of the trouble, and the procedure for solving the trouble, based on the signals acquired from the various sensors. FIG. 6 is an exemplary diagram showing an example of the trouble notification image displayed on the display unit 82 in the first embodiment of the present invention. In this embodiment, the case where the paper has run out is taken as an example, and the trouble notification image illustrated in FIG. 6 displays the place where the paper has run out and the solution method. The trouble notification image also displays an “OK” soft key for accepting a job resumption instruction after the trouble has been resolved, and a “copy cancel” soft key for canceling the job being executed. The first user solves the trouble according to the solving method displayed on the display unit 82, and touches the “OK” soft key to resume the job.

  Next, the CPU 21 displays an image for receiving a display instruction for displaying the name of another job that can be executed in parallel with the job currently being executed (hereinafter referred to as a name display instruction reception image) (step S107). In this embodiment, the CPU 21 displays an “other operation” soft key for accepting a display instruction for displaying the name of another job that can be executed in parallel with the currently executing “copy” job on the display unit 82 (FIG. 6). reference).

  The CPU 21 determines whether or not a job resumption instruction has been accepted by monitoring the touch of the “OK” soft key via the sensor unit 81 (step S108). When the “OK” soft key is touched after the first user replenishes the paper, the CPU 21 determines that a job resumption instruction has been received based on the data signal acquired from the sensor unit 81 (step S108: YES). The process returns to step S103.

  On the other hand, if the CPU 21 determines based on the data signal acquired from the sensor unit 81 that it has not received a job resumption instruction (step S108: NO), it determines whether or not an instruction to cancel the currently executing job has been received. (Step S109). Such determination is performed by monitoring the touch of the “copy cancel” soft key via the sensor unit 81.

  If the CPU 21 determines that an instruction to cancel the currently executing job has been received (step S109: YES), the CPU 21 cancels the currently executing “copy” job and ends the process. On the other hand, if the CPU 21 determines that an instruction to cancel the job currently being executed has not been received (step S109: NO), the process returns to step S108.

  In the present embodiment, the case where the name display instruction acceptance image is displayed when the trouble notification image is displayed (step S106) is described as an example, but the present invention is not limited thereto. For example, when starting execution of a job, in this embodiment, the name display instruction acceptance image may be displayed after the process of step S102, or may be configured to be displayed after the process of step S101. .

  On the other hand, when the name display instruction acceptance image is displayed on the display unit 82 in step S107, an operation of the name display instruction acceptance image by the second user can be assumed. That is, after the second user touches the “other operation” soft key and the CPU 21 receives the interrupt data signal (H level) from the sensor unit 81 through the bus N, the second processing system Processing is performed.

  Hereinafter, processing by the second processing system will be described. FIG. 7 is a flowchart for explaining processing by the second processing system in the first embodiment of the present invention. For convenience of explanation, the name display instruction acceptance image is displayed on the display unit 82 in step S107 under the same conditions as in the case of the processing by the first processing system described above, and the name display instruction acceptance image by the second user. A case where the touch is performed will be described as an example.

  The display instruction receiving unit 24 of the control unit 2 monitors the touch of the “other operation” soft key based on the data signal acquired from the sensor unit 81, and detects other jobs that can be executed in parallel with the currently executing job. It is determined whether or not a display instruction for displaying a name (hereinafter referred to as a name display instruction) has been received (step S201).

  When it is determined that the name display instruction has not been received (step S201: NO), the display instruction receiving unit 24 stands by until a name display instruction is received.

FIG. 9 is an exemplary diagram in a case where images related to execution of a plurality of jobs are displayed together in the first embodiment of the present invention. In the present embodiment, the above-mentioned “image relating to execution of a job that is already being executed” is the trouble notification image, and a preview image relating to execution of the job “confirming filing data” is displayed on the left side of the display unit 82 in the drawing. The trouble notification image is displayed together with the layout reduced on the right side of the display unit 82 as viewed in the drawing.

  Thereafter, the execution of the “filing data confirmation” job relating to the selected name is finished (step S207), and the process is finished.

  In addition, when a plurality of jobs are executed together, and when images related to the execution of the plurality of jobs are displayed on the display unit 82, when any job ends first, the execution of the job is performed. The display of the image is also ended, and only the image related to the execution of the job that has not ended is displayed on the display unit 82. For example, in the example illustrated in FIG. 9, when the “filing data confirmation” job ends first, an image related to the execution of the “filing data confirmation” job (left side in the drawing) from the image illustrated in FIG. 9. Disappears and only the trouble notification image is displayed entirely as shown in FIG.

  Since the image forming apparatus according to the present invention has the above-described configuration, it is not necessary to provide a so-called “dual view liquid crystal” or “triple view liquid crystal”, and further provide the “dual view liquid crystal” or “triple view liquid crystal”. A plurality of users can execute each job at the same time without feeling the image obstruction that may occur in the case of the image.
