Normally, when the display 83b of the operation panel is small and the amount of information to be displayed is insufficient, it is conceivable that another operation panel is provided to display two systems. Arranging the operation panel is uneconomical. On the other hand, in the present invention, as described above, the CPU of the information processing device such as a word processor connected to the main body CPU can communicate and check the communication. Becomes effective. For this reason, a mode is provided in which the display is displayed on the word processor display 84b and the operation panel display 83b on the copying machine side is deleted.

At this time, for example, if an automatic power-off (auto-power-off) function is set on the word processor, this automatic power-off function is activated and the display on the operation panel is erased. It is not suitable as a panel. Therefore, in the present invention, when the operation of the copying machine is entrusted to the display of the word processing side display panel 84b, an automatic power-off setting release signal is transmitted, the automatic power-off function is released, and the display of the operation panel 83b is displayed. It will not be erased. This is shown in the flowchart of FIG.

FIG. 7 is a flowchart for explaining another embodiment of the display function of the copying machine according to the present invention. Steps 5 to 5 of the "data update flowchart" shown in FIG.
7 and part of step 11 are modified. Here, only steps different from those in FIG. 6 will be described. That is, when the copier and the word processor are connected, and when the power is turned on, the initial data is transmitted to the main body operation CPU 83a and the word processor CPU 84a and displayed. At this time, the CPU 7
If communication is possible between the CPU 9a and the CPU 84a on the word processor side, step 15 : the display on the word processor side is determined to be valid and the display means on the copier operation panel is shut off. That is, it has a cutoff mode for cutting off the display on the copier operation panel. step16 : The automatic power shutoff function is set on the word processor side, and when the operation is given to the display panel on the word processor side, the automatic power shutoff function on the word processor side is released. Therefore,
In step 11 of the flowchart of FIG. 6, the received data of the word processor CPU 84a is transferred to the main body operation CPU 83a.
No need to send to

When the copier and the information device are connected and the power is turned on, various data of the main body including the function setting data of the main body of the copier are transmitted to the word processor CPU 84a as described above. You. As shown in the transition diagram of the copier operation panel screen display in FIG. 17, the copier operation panel is made up of a touch panel, and (a) the "basic screen" as an initial screen, (b) a "function selection screen", c) To select a selection screen such as a parameter setting having a copying function for each of the selection screens such as “image quality selection screen” and (d) “post-processing selection screen”, sequentially switch by key touch according to the arrow. Depending on the function to be set, the setting screen does not appear unless key input is performed several times. That is, as the number of functions increases, the number of screen switching increases, and so-called nesting becomes deep. Therefore, only limited information can be displayed on the display screen space of the copier operation panel as shown in FIGS.

Therefore, in the present invention, in the case of a word processor having a large display capability of the connected information equipment, the function transition diagram covering all the function settings by the transmitted function setting data is shown in FIG. It can be displayed as follows.

FIG. 8 is a diagram for explaining an example of a display screen of an information device (word processor) connected to the copying machine according to the present invention, and includes a touch panel. The display screen of the information device displays a transition diagram. On this transition diagram, the setting functions are shown in reverse video or the like, are displayed by numerical values as parameters, and the functions that can be set can be confirmed at a glance. By touching an area such as a function name displayed here, the setting status can be directly changed, and each time the function setting data is sent to the main body CPU, the main body data is updated.

Next, a case where a jam occurs on the copying machine body will be described. It is assumed that a jam occurs while the digital copying machine shown in FIG. 1 is copying. The conveyance of the recording paper is detected by a paper detection sensor (not shown) including a photo interrupter in the paper conveyance path. if,
When a jam occurs somewhere in the copying machine, the location is confirmed by the printer unit control CPU 79 (FIG. 2). Next, the corresponding jam display screen data and jam processing procedure comment text data are transmitted to the word processor CPU 84a based on the confirmed jam position information.

FIG. 9 is a view showing an example of a jam display screen for explaining a jam processing procedure of the copying machine according to the present invention.
In accordance with the data transmitted from 79, the location indication is performed by a notification unit that flashes the panel or knob to be jam-processed with light.

When the operator performs jam processing in accordance with the processing procedure, the removal of the jammed paper is confirmed by the paper detection sensor in the copying machine, and information is transmitted to the word processor according to the processing status of the jammed paper. The word processor CPU 84a changes the blinking of the knob to be processed to lighting according to the content, and moves the arrow → pointing to the procedure sentence (1 to 7) described in FIG. 9 to the next procedure of the procedure sentence. When the above process is repeated and the final seven steps are completed, the copying machine starts the initial operation and simultaneously transmits the basic screen display data to the word processor. The display on the word processor changes to the basic screen based on the transmission data. The details of the above operation will be described with reference to a flowchart.

FIG. 10 is a flowchart of a jam processing screen display according to the present invention. Step 1 : When the printing unit control CPU 79 detects the occurrence of a jam, the operation of the copying machine main body is stopped. step2 : The paper is detected by the paper detection sensor of each transport section, and the print section control CPU 79 recognizes the jam position based on the detection signal. Step 3 : The position display data corresponding to the recognized jam position is transmitted to the word processor CPU 84a, and at the same time, the processing procedure information (comment text) for the jam position is transmitted. step 4 : The word processor CPU 84a on the receiving side displays the contents according to the received information data on the screen. step5: operator in accordance with the screen display, the status of performing the jam handling print unit control CPU79 detects. step 6 : It is determined whether or not the jam processing has been completed. step7 : If the print unit control CPU 79 determines that the jam detection status has not changed and the jam processing has not been completed,
The print unit control CPU 79 transmits the current jam processing status to the word processor CPU 84a. step8: Update the jam processing procedure screen of the word processor side, continue this until the jam processing is completed. step 9 : If the jam processing is completed in step 6, the copying machine performs an initial operation and transmits the initial image data to the word processor. step10 : The word processor displays basic image data. step 11 : A normal copying operation is performed based on the display of the basic image data. Also, the display on the copier operation panel and the display on the information equipment are connected with an interface cable,
Another embodiment of a copier having a display function extension function for displaying an operation procedure, a message, or the like in conjunction with one or both of them according to the situation will be described.

In the flowchart of FIG. 12 , only the parts different from the flowchart of FIG. 5 will be described.

That is, if the power of the word processor is turned on and the output of the word processor reset signal (RES-IN) is "L", and the data requested to the word processor does not return as a redal, a retry is performed. If the operation is repeated several times and it does not return, it is regarded as a communication error, and regardless of the logic of the word processor reset signal (RES-IN), the display of the function setting and the setting of the department management function are performed on the operation panel side of the copier. Display. Step 17 : When the output of the word processor side reset signal (RES-IN) is "L", the display switching key 106 is switched to determine whether or not the display is displayed on the display of the copier operation panel. step18 : When the display is switched by the display switching key 106 on the copier operation panel, the main unit operation CPU 83a is instructed to transmit and display predetermined function setting data. Step 19 : When the function setting data is transmitted and displayed in step 16, or when the display switching key 106 does not indicate the display of the copier operation panel in step 15, the display switching key 106 is displayed on the information device (option side). It is determined whether or not the display has been switched to the display. Step 20 : When the display is switched to the information device side, predetermined function setting data is transmitted to the information device CPU 84a, displayed on the display, and waits for the operation of step 7 and the input of a key signal for selecting the display. Next, when a key signal is input, data from the main body operation CPU 83a is transmitted to the printer unit control CPU7.

After the PU initialization is performed, if the operation signal of the reset signal (RES-IN) on the word processor side is "H" thereafter, the operation panel of the copier, for example, the display of the operation panel according to the present invention shown in FIG. The copy function of the copier is set only by the user. When the word processor reset signal (RES-IN) is the reset signal "L", a communication check is performed.
However, since the display capacity of the display of the copier operation panel and the display of the information device are different, it may be required to display the information on any display having a large display capacity.

For this reason, in the present invention, after the communication check, the number of displayed dots (for example, the number of dots of the liquid crystal shown on the operation panel according to the present invention in FIG. 14 is 640 × 200)
Is transmitted to the information device side. The information device transmits the number of display dots in the X and Y directions to the copying machine as result data. Here, the printer unit control CPU 79 compares the previously stored number of display dots of the copying machine with the number of display dots of the received information device, and if the number of display dots of the display of the copy machine is large, The display and function settings are made on the main body copier.

On the other hand, when the display on the information device has a higher display capability, the display on the copying machine is turned off. Further, display data corresponding to the number of dots is transmitted to the information device. The maximum display data is 640 × 480 screen, and 640 × 4
FIG. 1 shows an example in which screen data is stored on the main body side for each of liquid crystals having a size of 00 and 640 × 320.
4 shows a display example of 640 × 400 dots.

FIG. 15 is a flowchart of another embodiment of the copying machine according to the present invention. Only the differences from the flowchart of FIG. 5 and the method of comparing the size of the display will be described. step 19: after the communication is checked, a word processor side reset signal (RES-IN) is "L", now, the X direction dot number of the copying machine side display of x _1, x ₂ and the information device side display X direction dot number, y ₁ Y-direction dot count of the copy side display and the y ₂ when the information device side display Y-direction dot number, with respect to the X direction to the x ₁ ≦ x ₂ Y-direction y ₁ ≦ y ₂ (here , X ₁ = x ₂ , y ₁ = y ₂
Excluding). However, since the standard number of dots in the current liquid crystal display is 640 dots in the X direction, the condition for the number of dots in the X direction in the flowchart is x ₁
= Keep with x _2. (For example, the liquid crystal used this time is x ₁ = 6
40, y ₁ = 200) step 20 : A display method is selected from the display dot data. step 21: if, when the number of dots y ₂ of the information equipment side display is determined to be larger than the dot number y ₁ indicator of copier at step 19, turn off the copier control panel display,
The predetermined function setting data is transmitted to the word processor CPU 94a on the information device side, displayed on the display, and waits for a key input such as a selection key. Conversely, when the number of dots on the copier operation panel display is larger than the number of dots on the display on the information device side, predetermined function setting data is set in the main body operation CPU 83a,
The result of the setting is displayed on the display of the copying machine.

As described above, the display for setting various functions which complicates the copying machine is displayed by utilizing the display unit of the word processor or the like, and copying according to the set various functions is performed. be able to. Therefore, in the digital copying machine, the read image of the document is temporarily stored in the memory 73 of FIG. 2 through various processes. This stored image can be displayed on the word processor side, and can be displayed in an image state (recording state) based on the setting function. By referring to this display, it is possible to change, process, or perform various edits to the desired image state again.

A procedure for confirming again the processed and edited image before outputting it by the function in which the read original data is set and changing the setting parameter will be described below. For example, in order to simplify the explanation, the function set on the operation panel is used to display the image data in “italics 15”.
The original is read by the scanner unit and the read data is temporarily stored in the image memory 7.
3 and sent to the word processor CPU 84a via the image processing CPU 74 at the same time. However, this is limited to the case where the output image confirmation key is specified by turning on the operation panel. On the word processor side, based on the image data sent and the setting functions set up to now, the word processor C
The image image processed and edited by the PU 84a is displayed.

After confirming the image, if it is "OK", for example, by touching the "OK; print start" section on the display of the word processor, the image processing side (copier side)
To allow output. If you are not satisfied with the image, touch the item for which you want to change the setting (or use the key on the operation panel of the copier or the keyboard of the word processor) to set the setting parameters (15 °, 50%).
Blinks and waits for change data input. When data is input using the keyboard of the word processor and the item portion is touched again, the input data is determined, and the image is reprocessed into an image corresponding to the parameter whose setting has been changed, and is displayed again.

When the output is permitted, the setting function and the parameter information at that time are sent to the CPU 74 on the main body side, and it is instructed to output after processing. The copying machine main body side CPU 74 converts the data in the image memory into the image processing unit 71 based on the transmission data.
By performing processing in and sending data to the output unit 72,
Obtain the desired copy. After the copy is completed, the basic screen data is sent to the word processor to return to the basic screen display. In the processing and editing of scanned image data,
In addition to changing the function settings, it is also possible to input character data and edit it together. The edited data can be sent to the copying machine and copied.
