The image obtained as a result of the editing process is stored in the image memory 15 again.

The operation unit controller 2 is connected to a C
It has a PU 22, a RON 23, a RAM 24, an interface 25, a key controller 2B, an LCD controller 27°, and a control section 28.

The interface 25 is connected to the interface 17 of the controller 1, and inputs various control signals from the controller 1 to the operating unit controller 2, and outputs instruction signals from the operating unit controller 2 to the controller 1.

The ROM 23 stores a program for controlling the display on the liquid crystal display device 62 and the input from the keyboard 81 when the device is used as a normal copying machine, which is the basic function of the device.

RAM 24 is connected from controller l to interface 2
5 and the data input from the keyboard B1 are temporarily stored.

The key controller 26 is a keyboard 61, and the LCD controller 27 is a liquid crystal display! It is connected to 182,
Perform each control. The display RAM 29 is connected to the LCD controller 27 and temporarily stores data to be displayed on the liquid crystal display device 62.

The operation of this device will be explained with reference to the flowchart shown in FIG.

First, the basic control program of controller l is read from ROW 13 to CPU 12 and initialized (10
0).

The CPU 12 sequentially reads programs from the RON 13 and outputs command data to the operating unit controller 2 (102).

Data input from the controller 1 to the operating unit controller 2 through the interfaces 17 and 25 is sent to the RA.
Once stored in M 24, CPU 22 stores it in RAM 24.
This data is sequentially read out from the controller 1, and a control signal is output to the LCD controller 27 in accordance with instructions from the controller 1. The LCD controller 27 reads necessary data from the display RA) 129 according to this control signal and outputs it to the liquid crystal display device 62. As a result, a message requesting selection between the normal copy mode and the application mode is displayed on the liquid crystal display device 62 (100
゜The operator looks at this display, selects either normal copy mode or application mode, and
Press the selection key on the keyboard 81.

The mode selection instruction input from the keyboard 81 is sent to the key controller 2B, bus 21. Interface 25 times? WomLte cPU 124: Input, CPU
12 determines mode selection (10B).

If the mode is normal copy mode, the CPU
12 follows the program read from 13 to RO,
Based on status information from the scanner 3, printer 4, and other mechanisms 7, a system ready signal is output to the operating unit controller 2. The system ready signal from CPU 12 is sent to bus 11. is input to the CPU 22 through the interfaces 17 and 25 and the bus 21;
U 22 is a display on a liquid crystal display device 62 in a normal copy mode stored in a ROM 23 and a keyboard 61;
A program for controlling is sequentially read out, and in accordance with the program, the display of the liquid crystal display device 162 is controlled, and the keyboard Elf is also controlled (10B).

First, the CPU 22 sends a control signal to the LCD controller 27. Based on this signal, the LCD controller 27 takes out display data from the display RAM 29 and outputs it to the liquid crystal display device iB2. As a result, the liquid crystal display device 62
indicates that the copy mode is normal, and prompts the user to select the same size, enlargement, or reduction ratio, and to select the paper size.

The operator selects the same size, enlargement, reduction ratio, paper size, etc. by pressing keys on the keyboard 81 according to these displays. A selection instruction is input from the keyboard 61 through the key controller 26, and the CPU 22 controls this input according to the key control program stored in the ROW 23.

For example, if an input is made from an unrelated key, it is determined to be invalid, and if a valid key input is made, the content of the key input is interpreted. Also, CPU 22 is RON 23
A control signal for the next display is output to the LCD controller 27 according to a display control program stored in the LCD controller 27 .

The LCD controller 27 uses this signal to switch the display R again.
The display data is read from the AM 29 and the next message is displayed on the liquid crystal display device 82.

Similarly, in the case of other conditions, for example, when a trouble occurs, the CPU 22 receives a signal to that effect from the controller 1, and transmits the control signal to the LCD controller 27 according to the display control program read from the ROW 23. The message is thereby displayed on the liquid crystal display device 62.

In this way, in the normal copy mode, the CP[I 22 of the operation unit controller 2 controls the display on the liquid crystal display device B2 and the input on the keyboard 61, and the CPU 12 of the controller 1 does not perform these controls. ,
Therefore, at this time, the CPU 12 of controller l
The burden has been reduced.

When the Stellar 7'10B determines that the mode is the application mode, one of the various application programs is read from the floppy disk by the floppy disk drive 5 and stored in the system memory 14 through the interface 17 of the controller 1. Stored. The CPU 12 reads this application program from the system memory 14, and performs various display controls and key input controls in accordance with the application program (110).

For example, a case will be described in which an image of a selected part of a document is copied.

The CPU 12 first reads the image of the document from the scanner 3 and temporarily stores it in the image memory 15 according to the application program read from the system memory 14.
A control signal is sent to the LCD controller 27 through the LCD controller 27 to cause the liquid crystal display device 62 to display a request to select a portion of an image from the document according to the content of the application program. The operator looks at this display, selects a part of the image, and inputs the instruction from the keyboard Bl.

Instructions are input from the keyboard 81 using the key controller 2θ
, CPU 12 through interfaces 25 and 17
is input. The CPU 12 controls this key input according to an application program stored in the system memory 14. That is, for example, a key input specifying a part of an image is interpreted as selecting that part, and an input specifying an image outside the range of the document is interpreted as invalid.

In accordance with such an image selection instruction, the CPU 12 reads out the image from the image memory 15 and causes the image processing circuit 16 to edit the image. That is, from among the images read by the scanner 3, only the portion designated by the operator is selected and a composite image is created. The newly created image is stored in the image memory 15 again.

Next, the CPU 12 outputs a signal to the LCD controller 27 through the interfaces 17 and 25, and the
The controller 27 causes the liquid crystal display device M82 to display a request for an instruction to start printing. When the operator sees this display and inputs a print start instruction from the keyboard 61, the CPU 12 reads the edited image from the image memory 15 in response to this start instruction and sends a signal to the printer 4 instructing it to print. The edited image is thereby printed by the printer 4.

In this manner, in the application mode, the CPU 12 of the controller 1 controls the display on the liquid crystal display device 82 and the input from the keyboard 61, and the CPU 22 of the operation unit controller 2 does not function. The operation unit controller 2 is simply a terminal, and only controls data transfer and does not control display contents.

According to this embodiment, the normal copy mode and the application mode are switched, and the display and key input are controlled by the operation unit controller 2 in the normal copy mode, and by the main body controller 1 in the application mode. . Therefore, it is possible to reduce the heavy workload that the controller 1 of the main body of the conventional intelligent copier is burdened with by various functions.

Although the above embodiments have been described with respect to an intelligent copier, the present invention can also be applied to display control when an office computer is used as a word processor as a basic function and is switched to other uses.

Effects According to the present invention, in addition to variable input control means that performs input control according to various intelligent functions, fixed input control means that performs input control when using one basic function is provided, When using one intelligent function, the input is controlled by the fixed input control means, and when using other various intelligent functions, the input means is controlled by the variable input control means, so only the variable input control means is used. The burden on the variable input control means is reduced compared to control of the input means, and efficient input control can be performed.
