The printer 13 includes a unit for double-sided printing, and prints a monochrome or color image on one side or both sides of the paper supplied from the multi-level paper stocker 13. The finishing unit 12B realizes a booklet function for performing saddle stitching by a staple, a sorting function, a punching function, and the like. The power supply circuit 14 supplies electric power required everywhere in the multifunction machine 1. The control circuit 15 includes a ROM 151 that stores a control program, a CPU (Central Processing Unit) 152 that executes the control program, and a RAM 153 that is used as a work area for executing the program. The image processing circuit 16 is responsible for various processes including bitmap development in copying and printing. The facsimile communication modem 17 is used for communication via a public line. The external connection interface 18 is used for connection with a LAN cable. The storage 19 is a mass storage device such as a hard disk drive. The storage 19 is provided with a memory area for storing data related to the control of the multifunction machine 1 and a so-called box which is a memory area for storing various document files.

  As shown in FIG. 2, the display device 2 includes the display 21, the input device 22, the operation screen storage unit 23, the moving image data storage unit 24, the reproduction order determination unit 26, the reproduction unit 27, the table management unit 28, and the screen display unit. 29. The input device 22 of this embodiment is a touch panel. The touch panel overlaps the display surface of the display 21 and outputs a signal corresponding to the position in the display surface touched by the user of the multifunction device 1 as the operator. The operation screen storage unit 23 and the moving image data storage unit 24 are memory areas provided by the RAM 153 and the storage 19. The RAM 153 is used for temporary storage of data, and the storage 19 is used for storage of table data that requires nonvolatile storage. The reproduction order determination unit 26, the reproduction unit 27, the table management unit 28, and the screen display unit 29 are functional elements realized by the screen display program and the CPU 152 as a computer that executes the program.

  The operation screen storage unit 23 stores image data for displaying each of a plurality of hierarchical operation screens. The operation screen includes a later-described playback setting screen. The operation screen storage unit 23 is accessed by the screen display unit 29, and an operation screen is displayed based on the image data read from the operation screen storage unit 23. The displayed operation screen is switched according to the operation input.

  The moving image data storage unit 24 stores data for reproducing a video representing an example of operation input related to one or a plurality of operation screens. In the present embodiment, display transitions (switching of operation screens and state changes of the respective screens) when registering examples of operation inputs are reproduced based on control data managed by a moving image management table T1 described later. Video reproduction means reproduction of such a display. It may be reproduced so that the screen is switched at the same timing as that at the time of registration, or may be advanced as a whole or may be partially advanced or delayed depending on whether or not the mode is changed. When a plurality of operation screens are involved, a series of images to be reproduced has a portion corresponding to each operation screen. For an operation screen in which some operation (key, button, or tab is pressed) at the time of registration, for example, the display change accompanying the operation is displayed in the video so that the pressed key is highlighted. For an operation screen that has not been operated, only that operation screen is displayed.

  The moving image data storage unit 24 stores a mode change management table T2. The mode change management table T2 associates each of a plurality of operation screens related to an example of operation input with the mode change count that is operation history information of each operation screen. The number of mode changes indicates the cumulative number of mode change operations performed on each operation screen, and is involved in determining the playback order of the operation screens during video playback.

  The reproduction order determination unit 26 determines a reproduction part and a reproduction order in the above operation input example. The reproduction order determining unit 26 refers to the mode change management table T2 and searches for operation history information (mode change count) corresponding to the condition specified by the user through an operation input on the reproduction setting screen. Among a plurality of operation screens related to the registered operation input examples, an operation screen associated with the operation history information corresponding to the condition is selected as a reproduction target. The reproduction order determination unit 26 changes the reproduction order of the selected operation screen according to the condition specified by the user. Details will be described later.

  The reproduction unit 27 reproduces a video representing the part corresponding to the operation screen selected by the order determination unit 26 in the registered operation input examples in the order after the replacement by the order determination unit 26. At the time of reproduction, the reproduction unit 27 refers to the moving image management table T1.

  The table management unit 28 updates the mode change management table T2 according to the operation input. When an operation input is performed during the reproduction of the video by the reproduction unit 27, the table management unit 28 receives the operation input and updates the operation history information of the operation screen corresponding to the operation input in the mode change management table T2.

  The screen display unit 29 displays an operation screen on the display 21. For the display, data of a plurality of operation screens stored in the operation screen storage unit 23 is used. The display is switched by the screen display unit 29 according to the operation by the user. When a signal indicating a position corresponding to an operation key in the displayed operation screen is input from the input device 22, the screen display unit 29 recognizes that the operation key is pressed. Further, when the registration start of the example of the operation input is instructed from the user, the screen display unit 29 receives the control data necessary for reproducing the display transition from the start of the registration until the end of the registration is instructed. Write to.

  Hereinafter, the function of the display device 2 will be described in more detail.

  As shown in FIG. 3, the operation panel 10 includes a display 21 for displaying an operation screen and various fixed operation keys arranged on both sides thereof. The fixed operation keys include a start key 101, a stop key 102, and a capture key 103 related to registration of an example of operation input. In FIG. 3, the display 21 displays a copy basic screen Q10. The copy basic screen Q10 is the highest-level operation screen in the copy mode in which the multifunction machine 1 operates as a copying machine. The copy basic screen Q10 includes a message column 201 indicating the setting value of the operation state and the number of copies, a menu 202 with options for mode setting for determining details of the job in the copy mode, and a job display column for displaying the job registration status 203 etc. are arranged. In FIG. 3, the message “Can copy” is displayed. If the user presses the start key 101 in this state, the copy job is started.

  The user can set the desired mode by appropriately switching the operation screen starting from the operation input on the copy basic screen Q10. At that time, the user can register the contents of a series of operation inputs as an operation template. The above-described screen display unit 29 is responsible for registration processing. As shown in the flowchart of FIG. 4, the registration process is executed from the start instruction (for example, pressing of the capture key 103) until the end instruction (for example, pressing of the stop key 102). Every time the mode is set, the moving image management table T1 is updated (# 101 to # 104).

As a specific example of registration, there is a case where an operation for setting and confirming the following modes (1) to (8) is performed in the copy mode.
(1) Select black as the color mode.
(2) Regarding the image quality / density setting, only the setting content is confirmed, and the default setting is not changed.
(3) Specify the booklet mode.
(4) Regarding stamp / page printing, only the setting contents are confirmed, and the default setting is not changed.
(5) Select saddle stitch as the finishing mode.
(6) Regarding the paper setting, only the setting content is confirmed, and the default setting is not changed.
(7) Regarding the magnification setting, only the setting content is confirmed, and the default setting is not changed.
(8) Specify 20 copies for the number of copies.

  As shown in FIG. 5, the screen number assigned to each operation screen, the coordinate information of the position pressed on the screen, and the contents of the mode change or setting are registered in the moving image management table T1. In this embodiment, link information indicating the link status of the hierarchical operation screen is also registered.

  In the present embodiment, the pressing of the operation key on the operation screen displayed by pressing the “image quality / density” and “application” tabs in the copy basic screen Q10 is actually for convenience of control. In some cases, the screen number of the copy basic screen Q10 (10200000 in the example) is registered instead of the screen number of the pressed operation screen.

Each row in the registration order 1 to 17 in the moving image management table T1 in FIG. 5 indicates that the next operation has been performed. In the figure depicting the operation screen, the operation keys, buttons, and tabs to be pressed are indicated by a thick dashed box. However, this is a consideration that makes it easy to understand the correspondence with the explanation, and does not mean that a thick dashed box is added in video reproduction.
Registration order 1: The color setting button 231 is pressed on the copy basic screen Q10 as shown in FIG.
Registration order 2: The black key 2614 is pressed on the color setting screen Q11 as shown in FIG.
Registration order 3: The image quality / density tab 263 is pressed on the color setting screen Q11 as shown in FIG.

Registration order 14: Display is returned from the paper setting screen (not shown) to the copy basic screen Q10.
Registration order 15: The magnification setting button 233 is pressed on the copy basic screen Q10.
Registration order 16: Display is returned from the magnification setting screen (not shown) to the copy basic screen Q10.
Registration order 17: The number of copies is set to “20” using the numeric keypad of the operation panel 10.

  The contents of the mode setting by the above series of operations are stored in the moving image data storage unit 24 as moving image information. At that time, the user can designate a registered name. Here, it is assumed that the registered name is “booklet”.

  The user can select moving image information to be displayed by video reproduction from a plurality of moving image information registered by the user or other users on the moving image selection screen Q13 shown in FIG. For example, when the option key 217 is pressed in the example of FIG. 8, the moving image information registered under the name “booklet” is set as a reproduction target. Thereafter, when the user performs a playback start key (for example, pressing of the OK key 278), playback starts. The user confirms various mode setting states by viewing the reproduced video, and changes the mode setting as necessary.

  Next, the operation of the multifunction machine 1 will be described with reference to the flowchart of FIG.

  The display device 2 selects moving image information to be reproduced in accordance with a user instruction, and waits for an instruction to start reproduction (# 201, # 202). In response to the pressing of the playback start key, the display device 2 performs a playback order determination process, and then starts playback (# 203, # 204). The playback order determination process is a process of switching the playback order of a plurality of operation screens related to the registered moving image information in accordance with user-specified conditions. This process will be described in detail later.

  When the user presses the start key 101 (see FIG. 3) during or after the reproduction, the multifunction device 1 starts a job (# 205, # 211 and # 212). The job mode is a mode in which the registered moving image information is maintained or a mode changed after the start of reproduction based on the mode, and is set by a job management unit (not shown) realized by the control program of the multifunction machine 1. If there is an operation screen that has not been reproduced among all the operation screens related to the moving image information selected as the reproduction target, the mode registered in the operation screen is set as the job mode (# 211).

  If the start key 101 is not pressed during reproduction, the display device 2 continues reproduction (# 205 to # 210). When an operation for changing the mode on the operation screen is performed at the stage where any one of the operation screens sequentially displayed is displayed during the reproduction, the display device 2 displays the mode change table T2 shown in FIG. The job management unit sets the mode instructed to be updated and changed to the job mode (# 205, # 206, # 208, # 209). That is, the mode change operation during reproduction is reflected in the job mode. On the other hand, if no operation to change the mode on the operation screen is performed while any one of the operation screens is displayed for a predetermined time, the mode registered on the operation screen is set to the job mode. (# 206, # 207).

  In the present embodiment, the job mode is automatically set. However, a configuration in which only the video reproduction of the operation example is automatically performed and the user sets the mode may be employed.

  In the reproduction order determination process, the reproduction order of the operation screen is determined according to the user designation on the reproduction setting screen Q14 illustrated in FIG. 10 and the mode change management table T2 in FIG. The specified items on the playback setting screen Q14 are playback reference settings and playback rule settings.

  The playback standard setting is “all video playback” to play back the entire selected video information (example of operation input), or only the part corresponding to the operation screen with the mode changed “only with mode change” "Is selected. Operation keys 281 and 282 are used for setting. In the example of the moving image management table T1 in FIG. 5, the user does not set the mode as in stamp / page printing (the default setting is used), but there is an operation screen for checking only the mode. A user who wants to exclude such an operation screen from the reproduction target may select “only with mode change”.

  For the playback rule setting, in order to determine the playback order, select “order with the highest number of changes” giving priority to the operation screen with the most mode changes, or “order with the lowest number of changes” giving priority to the operation screen with the few mode changes. It is a setting. Operation keys 283 and 284 are used for setting. In many cases, the user who has selected “in order of increasing number of changes” has only to set the necessary mode on the operation screen that is played back early, and then check the playback content. On the other hand, operation screens that have hardly changed mode are often screens for advanced settings. It can be said that the selection of "" is effective.

  The mode change management table T2 in FIG. 11 manages the number of times the mode is changed during moving image reproduction for each operation screen on which mode setting is performed. The mode change management table T2 can be configured to manage the number of times of mode change for each user and for each operation screen like the mode change management table T2c of FIG. If it does so, it will become possible to change a reproduction | regeneration order according to the user specified by user authentication.

  FIG. 12 shows three reproduction orders 1 to 3 determined by applying the mode change management table T2 of FIG. 11 to the moving image management table T1.

  In playback order 1, the playback reference setting is “all video playback”, and the playback rule setting is “in order of increasing number of changes”. The “number of copies setting” of screen number 90000000 and the “image quality / density setting” of screen number 10227000 are played preferentially.

In the reproduction order 2, the reproduction reference setting is “only with mode change”, and the reproduction rule setting is “in order of increasing number of changes”.
Similar to the playback order 1, operation screens with a large number of mode changes are preferentially played back, and operation screens whose modes are not changed from the default are excluded from playback targets.

  In the playback order 3, the playback reference setting is “all video playback”, and the playback rule setting is “in order of decreasing number of changes”. Play in ascending order of mode change. When the number of mode changes is the same, the operation screen that has not been changed from the default mode when the operation is registered is preferentially reproduced with respect to the operation screen whose mode has been changed.

  As a modification of the order determination, in step # 206 of the flowchart of FIG. 9, it is possible to check whether or not the user has designated an operation screen to be preferentially reproduced without changing the mode. In this modification, the mode change management table T2b illustrated in FIG. 13 is applied to order determination. In the example of FIG. 13, priority is given to reproduction for the paper folding / saddle stitch setting screen with screen number 10215030.

  FIG. 14 shows the reproduction order 4 determined by applying the mode change management table T2b of FIG. 13 to the moving image management table T1.

In the reproduction order 4, the reproduction reference setting is “only with mode change”, and the reproduction rule setting is “in order of increasing number of changes”.
The paper folding / saddle binding setting screen for which preferential playback is designated is played back next to the upper copy basic screen Q10 (screen number 1020000) and the finish setting screen (screen number 10215000) according to the screen hierarchy.

  In the above embodiment, it is assumed that the moving image management table T1 and the mode change management tables T2, T2b, and T2c are stored in the multifunction device 1, but the multifunction device 1 is connected as shown in FIG. The server 9 in the network may manage data relating to the moving image playback of the operation example. In this case, the plurality of multifunction peripherals 1 and 1b can share and use data. Depending on the number of mode changes indicated by the mode change management tables T2, T2b, and T2c, the display time for reproducing a moving image of each operation screen may be increased or decreased, for example, a screen with a large number of times is shorter than a screen with a small number of times. .

  In the above-described embodiment, the MFP 1 has a function of registering moving image information that reproduces an example of operation input. However, the moving image information is stored in an external office device management department of a service center or a company to which the user belongs. It is possible to use a form that is created by a device and that allows the multifunction device 1 to acquire moving image data from an external device. The moving image information may be information representing an example of operation input. The present invention is not limited to control data that defines screen display switching as in the above-described embodiment, but may be movie data that represents a series of operations in live action or CG (Computer Graphics), or represents operations in a slide format. It may be image data.

  According to the above-described embodiment, the transition of the display at the time of registration is reproduced based on the control data (screen number and coordinate information) managed by the moving image management table T1, so that a series of processes as described in Patent Document 1 are performed. Compared to sequentially displaying captured images acquired at a plurality of stages in the above operation, the amount of data to be stored for video reproduction can be greatly reduced. In addition, since the user can change the mode on the reproduced and displayed operation screen, the user can cause the multifunction device 1 to execute a job for partially changing the previously registered mode setting with a simple operation. In order to reproduce the captured image and display the operation screen, the display must be enlarged, but this is not necessary in the above-described embodiment. However, a captured image in the past operation may be reproduced, and the captured image and the operation screen for changing the mode may be switched and displayed. An example of how the captured image is reproduced is shown in FIG. In the example of FIG. 17, the capture image VQ12 of the booklet setting screen Q12 of FIG. 7 is displayed in the reproduction screen Q13b.
