Next, prior to explaining the operation of the editor, each of the trimming mode, masking mode, and moving mode will be briefly explained with reference to FIGS. 11A to 13B.

In trimming mode, the designated four points P+ (XI, yl), P3 (XI
, Y2 ), P2 (X2 , Y2 ) and P4 (
Only the portion of the image corresponding to the rectangular area 154 connecting the angles X2°Y+) is left, and the rest of the image is erased as shown in FIG. 11B.

In the movement mode, as shown in FIG. 13A, the coordinates P+ (XI) of the leading or trailing edge of the moving image.

Y+), and then specify coordinates P4 (X2, Y+) of a point to be moved while keeping the Y coordinate approximately constant.

Then, when the toner image is transferred to the recording paper, the X coordinate position X1 moves to X2, and an image as shown in FIG. 13B is formed. That is, in this mode the LED
Instead of using the array 46, the sheet feeding timing is controlled by coordinate data, as will be described later.

Here, with reference to FIGS. 14 and 15, this LED
The array 46 will be explained. As shown in FIG. 14, the LED array 46 includes, for example, 64 LED elements 15.
It includes rod-shaped units in which 8, 158, . . . are closely arranged in the horizontal direction. In this LED array 46,
Further, a driver IC 160 for controlling blinking of each LED I 158, a resistor array 162 for adjusting the supply voltage of the LED element 1581\, and a connector 1
64 are provided. LED element 158, driver 160
and resistor array 162 are connected as shown in FIG.

The LED elements 158, 158, . . . are driver I
C160 input terminals SIN, CLOCK and LA
Lighting is controlled by pulses supplied to TCH. When turning on a desired LED element 158 to remove the electric charge on that part of the photosensitive drum 38, the driver IC to which the LED element 158 to be turned on is connected.
A control pulse is applied from the input terminal SIN in synchronization with the clock pulse so that the output terminal of 160 becomes a low level. Then, when a latch pulse is supplied from the input terminal LATCH, the output terminal of the driver IC 160 connected to the LED element 158 to be lit is held at a low level, so that the LED element 158 maintains the lit state.

To light up all 64 LED elements 158, it is sufficient to set all 64 control pulses supplied from the input terminal SIN to a low level and hold all the low levels with a latch pulse.

In addition, during masking, which will be described later, the LED elements 158 between two points to be masked are lit for a predetermined period of time, and during trimming, the LED elements 158 only between the two points are turned off, and the LED elements 158 outside the two points are falsely lit. become. Note that such lighting/extinguishing of the LED elements 158 is controlled by converting the Y coordinate data obtained by the editor described above into position data of the 64 LED elements.

Next, key operations and liquid crystal display of the editor will be explained with reference to FIGS. 5 and 6.

Before starting the editor operation, the operator first inserts the IC card 116 into a predetermined insertion/removal opening of the editor main body 122, as shown in FIG. Next, the operator starts editing operations, but the editor of this embodiment, as mentioned above,
In addition to editing instructions, it is also possible to make copying instructions such as the number of copies, magnification, and size of paper to be copied, so if necessary, select the desired copy size -14 and make instructions. FIG. 6 is a detailed diagram of the liquid crystal display (2) of the editor main body 122 in FIG. (2) is a liquid crystal display consisting of 40 characters x 2 columns, and information such as editing instructions is displayed in the old system and copying instructions are displayed in the lower row. The lower part of the copy instruction information includes, from left to right, the following information: "original size,""papersize,""copymagnification,""number of copies,""density per copy,""1 binding margin,""frameerasing," and "continuous copying of one page." Is displayed. In the initial state, document size = no information, paper size - LD (LEDG
(abbreviation of ER), number of copies = 001, copy density = 4, binding margin = 0, frame eraser = 0, vane quick copy-N, and if necessary, the operator can use the keys ( ) provided on the editor main body 122. 128 to change each information as follows.

There is a cursor section ◎ below the character section on the liquid crystal display, which allows a black underline to be displayed. First, the operator presses the cursor keys 128f and 128 in Figure 5.
By operating g, you can move the cursor to the right or left to locate the information you want to change. Full: 1-Figure (
To explain based on FIG. 16), for example, when an operator wants to change the paper size from the initial state of LD to LG,
First, check whether the cursor key is on the left or right side of the paper size display section, and if it is on the left, press the cursor key 128f, and if it is on the right, press the cursor key 128g. The cursor then moves to the right or left and moves below the first character of the next information display section. After moving the cursor below the paper size display, press the gun key 128e. Then, the paper size display is changed to LD-LG. At this time, if you keep pressing this change key, I, D →
L G -I, T R+S T R→LT→ST→L
They are changed one after another to Zyric in the order of D.

Although an example of only paper size has been described here, other copy instructions can be changed by moving the cursor key and pressing the change key.

Also, the changed data is sequentially transferred and stored in the RAM in the IC card. The zoom keys 128d and 128C can change the magnification display area without moving the cursor. That is, when the zoom up direction key 128c is pressed, 1
The magnification increases by % UPL, and if you do not press 128d, the magnification decreases by 1%.

If the operator wants to return the paperback to its initial state, it can be returned to the LD using the change key, or it can be easily initialized using the clear key 128b.Use this clear key. For example, other display sections can be initialized in the same way by moving the cursor.

Note that the all reset key 1288 is
This is used to initialize the data on the C card 116, and especially to initialize everything used when the IC card 116 is inserted into the editor 122. This input method is effective when input and display space is small, and the input operation is also simple. Therefore, in addition to being used for this editor, it can also be used for input display on the main body of the copying machine. In that case, information can be transmitted directly to the memory of the copying machine.

As described above, the input of these keys is detected in the same manner as the editing instruction described later.

Furthermore, editing instructions to be described later can be given without using the cursor keys.

Next, operations of the editor will be explained based on flowcharts shown in FIGS. 17 to 19.

First, the user presses a desired editing mode key on the tablet, for example, a trimming key, using the input pen 130 to specify the trimming mode. At this time, as described above, the switch built into the input pen 130 is turned on, and the output is
10 interface 148 to MPU 142 . In steps Sll to S13, the MPU 14
2 constantly detects the input state of the input Ben switch,
When the switch is turned on, the process advances to step S15 and reading of the coordinates of the position pressed with the input pen 130 is started.

In step 315, the MPU 142 drives and controls the tablet circuit 126 via the I10 interface 148, and inputs the coordinate data of the position pressed with the input pen 130 using the position coordinate detection method described above. Next step 3
17 to S19, the MPU 142 stores the ROM1 in advance.
The key coordinate data table stored in 44 is compared with the coordinate data detected by the input pen, and if the detected coordinate data is the key coordinate, the process advances to step S29. In this way, the above-mentioned copy instruction key is also detected in the same manner.

If the data is not the key coordinate, step 3
Proceeding to S21 to S23, the M PU 142 reads the edit mode flag from the RAM 146 and has already changed the editing mode.
Determine whether the code is specified.

Here, if any edit mode flag is set, the coordinate data may be position data of an area to be edited in that edit mode, and the process proceeds to step S71. If the edit mode flag is not set, the process advances to steps 325 to 327, where the coordinate data is canceled as erroneous data due to operator error or data line noise, and an error message is displayed on the liquid crystal display 132 (FIG. 6). Ru.

Since the operator has now pressed the trimming key, the process advances to step S29. In step 529, the coordinate data is compared with the coordinate data of the trimming key. If the data match, the MPU 142 determines that the trimming mode has been designated and proceeds to step S31. In step S31, the trimming mode flag is stored in the RAM in order to remember that the trimming mode has been designated.
Set it to 1.46. Then, in step S33, the trimming mode is displayed on the liquid crystal display 132.

If the coordinate data is not of a trimming key, the process proceeds to steps 335, 342, 347, etc., and processes for each key are executed.

The operator then places the original document 124 on the tabletop 126'' with the original surface facing upward. At this time, the document is placed so that its center in the width direction coincides with the center mark 122a of the editor main body 122. Thereafter, the operator specifies diagonal points P1 and P2 of the area for l-limin, such as area 154 in FIG. 11A, with input pen 130.

Since the trimming mode flag has already been set, the process advances to step S71. Step 571-8
At 73, a flag is checked to remember that point P1 has already been specified, namely the P1 flag. When the point P1 is designated with the input pen 130, the P1 flag has not yet been set, so the step advances to S75.

In steps 375 to S79, coordinate data X of point P1
I + Y l and the P1 flag are stored in the RAM 146, and a message indicating that the data at point P1 has been accepted is displayed on the liquid crystal display 132.

When the point P2 is specified with the λ capen 130, the vPI flag has already been set, so the process advances to step S81 and the point P2 is specified.
Check the flag. Specify point P2.

At this point, the final P2 flag has not been set, so the step proceeds to 885. In steps 885 to S89, coordinate data X2. Y2 and P
27 is stored in the lag RAM 146, and a message indicating that point P2 has been accepted is displayed.

Here, in step 583, if the P2 flag is already set, that is, the operator selects the point P1. P2
After specifying , if any point other than the previously operated key is specified, an error message is displayed on the liquid crystal display 132 as shown in steps 391 to 393.
The coordinate data of that point is distorted by the kiln cell.

Next, after specifying the points Pi and P2, the operator presses the memory key on the input ben 130. Then MPU
142 determines this, and the process proceeds to step S49.

In step S51, since the P2 flag should have already been set, the MPU 142 assumes that the editing operation is completed and proceeds to step S53. In step 353, the edit mode flag (here, the trimming mode flag) stored in the RAM 146 and the coordinate data of points PI and P2
It is transferred and stored in the RAM 138 in the C card. Then, in step S55, RAM is loaded for the next editing operation.
The edit mode flag and PI+P2 flag in 146 are reset.

If the P2 flag is not set in step S51, the editing operation has not yet been completed, so an error message is displayed as shown in steps S57 to S359, and the coordinate data of the memory key is canceled.

Here, if the operator makes a mistake in the input operation and wants to cancel the data input just before, input
If the clear key is pressed for 0, coordinate data and flag cancellation processing is performed in step 36g.

Further, if the reset key is pressed, step S67
The RAM 138 in the IC card 116 is initialized by the smell, and all data related to the editing mode is cleared. At the same time, in step 8694m, the edit mode flag and the PI and P2 flags in the RAM 146 are reset.

FIG. 20 is a block diagram of the control section of the main body of the copying machine. The copying machine is controlled by a microcomputer system 11 including an MPU 168. This microcomputer system includes a ROM 170 for storing control programs connected to this MPU 168, and a ROM 170 for temporarily storing data and for storing data necessary for control when the MPU 168 is controlling. RAM 172 having various flag areas, and MPU 16g are I10 interface 1 for controlling input/output of internal equipment of the main body.
74 included.

The input port of the I10 interface 174 receives data from the key matrix 180 of the operation panel 110 and the output of a sensor circuit 182 including a paper size sensor.

In addition, the output port of the I10 interface 174 has
A driving device 184 such as a motor or a solenoid, and a partial erase lamp or LED array 46 for erasing electrostatic latent images that are no longer needed due to editing are connected. The operation of this LED array 46 has been described above.

Further, a servo motor controller (LSI) 176 is connected to the MPU 142, and a DC servo motor 178 for reciprocating scanning of the exposure lamp 28 is connected to an input/output terminal of this controller 176.

The RAM 138 in the IC card 116 is connected to the MPU 168 by a pass line, similar to the control section of the editor.

Next, referring to FIG. 20, the operation of the copying machine will be described based on the flowchart shown in FIGS. 21, 22, and 23, and the editor and main body display diagram (FIG. 24).

When the editor finishes specifying the position for editing the manuscript 124, the operator takes out the IC card 116 from the editor and inserts it into the IC card slot 118 of the main body 12, as shown in FIG. and automatic document feeder 26
Open the original 124 (or 18 ). After that, the automatic document feeder 26 is closed and the document 124 is placed on the document table 1.
4 Fix it on top.

Note that the document 18 can also be set using the automatic document feeder 26.

Here, when the operation key 114A shown in FIG. 1 is operated,
As shown in the flow diagram of FIG. 23, the data stored in the RAM 138 of the inserted IC card 116 is
The data is transferred to the RAM 172 of the main body control section shown in FIG. Therefore, before operating the start key 120, the operator operates the operation key 114A to load data such as the editing mode, number of copies, and magnification stored in the IC card 116 into the RAM 172. Then, the display on the main unit automatically changes according to the loaded data and enters the standby state for copying (Figure 24).
. Then, the operator operates the start key 120 to start the copying operation.

The copying operation is naturally performed based on the content of the copying instruction loaded into the main body, but since the copying instruction information is the same as in the conventional method, only the operation based on the editing instruction will be described in detail here.

Note that the main body of the copying machine can of course perform normal copying operations without installing the IC card 116;
Even if the C card 116 is installed, the card 112 or 114
It is possible to set each copy mode as desired.

When the start key 120 is operated, in the first step 5111 of FIG. 18A, a main motor (not shown) for driving the photosensitive drum 38 and the like is turned on.

When the rotation of the main motor becomes stable, that is, when 0.5 sec has elapsed since the main motor was turned on, the solenoid of the cleaning device 82 is turned on and the tip of the blade 84 is brought into contact with the photosensitive drum 38. When a predetermined period of time has passed since the solenoid was turned on, that is, when 100 m5ec has passed so that no load is applied to W* at the same time,
Proceed to the next step 5113.

In step 5113, the microcomputer 168 checks the signal from the sensor circuit 182 (FIG. 20) and determines whether the exposure lamp 28 is at the home position, that is, whether the exposure lamp 28 is located on the left side of the main body 12. to decide. If the exposure lamp 28 is at the home position, the process proceeds to the next step 5117; if not, in step 5115, the exposure lamp 28 is reversed to the home position 178 (FIG. 20) and the exposure lamp 28 is returned to the home position. This servo motor 178 is turned off by interrupt processing, which will be described later.

In step 5117, the transfer corotron 62 is turned on. After this transfer corotron 62 is turned on, the process continues to the next step 5119. In step 5119, it is determined whether the copy is a manual feed copy, that is, whether the paper 44 is fed manually rather than from the paper feed cassette 66 or 74. If it is a manual copy, the process advances to the next step S121, and the solenoid of the cleaning device 82 that was turned on in the previous step 5111 is turned off.

If it is not a manual copy, the process proceeds to step 5123 without passing through step 5121.

In the next step 5123, the V paper feed motor is turned on again, the paper feed row 272 starts rotating, and the paper 44 is conveyed toward the register roller 80. At the same time, the solenoid of the cleaning device 82 is turned off. The solenoid is turned off twice in the case of manual copying in the previous step 5119, that is, in the case of passing through 5121, but since the off signal is only supplied, there is no equivalent change in the solenoid. . 20 from solenoid off
After 0 m5ec has elapsed, the process advances to the next step 5125. During this 200m5ec time, the paper feed clutch 7 was turned on and paper 4
This is the time to judge the JAM when 4 is transported.

In step 5125, it is determined whether the exposure lamp 28 is in the Baume position, and if it is in the home position,
Proceed to the next step 5127.

In step 5127, the microcomputer 168 determines whether the data loaded from the IC card 116 into the RAM 172 specifies moving the image to the right in the movement mode. That is, the movement mode flag stored in the RAM 172 and the X coordinate data X of point P1
1 and the X coordinate data X2 of point P2, it is determined whether the image is set to move to the right. If the image is set to move to the right, step 5
The process proceeds to step 129, and if the right movement of the image is not set, the process proceeds to step 5151.

In step 5129, it is determined whether this is the first copy. If it is the first copy, the process advances to step 5131; if it is not the first copy, that is, if it is the second or later copy, the process advances to step 5145.

In step 5131, after 300 m5ec has elapsed, the servomorph 182 is rotated in the normal direction to scan the exposure lamp 28. In the next step 5133, it is determined whether the exposure bar 28 is located at the image position.

The image position is the position of the document table at which the image of the document 124 begins to be formed as an electrostatic latent image on the photosensitive drum 38. If it is not the image position, in the next step 5135 the time from the Baum position to the image position is counted by a counter. Once the image position is reached, proceed to the next step 5137
Proceed to. In step 5137, servomorph 178 is turned off, and then 20On+sec later, servomorph 178 is reversed.

In this way, when right movement is set and the first copy is being made, the time from the home position to the image position is unknown, so before starting copying, move the exposure lamp 28 to determine the time. I need to measure it.

Next, in step 5139, it is determined whether the exposure lamp 28 has returned to the home position.

If it returns to the Baum position, the process proceeds to the next step 5141, and in step 5141, the time to move the image to the right is equal to the time counted in the previous step 335 and 102
0102O. This 1020102O is the step 515 which will be described later.
200m5ec set in 1, 300m5ec after step 5153, 10 set in step 5155
0m5ec and state S17]
It is the sum of 0m5ec. In other words, in order to move the image to the right, it is necessary to advance the paper feed before the formation of the latent image, but this advance # time is the original start time of paper advance, that is, the resist clutch on in step 5175. Determine whether it is shorter than the time until the timing.

If the image movement time is greater than the sum of the value counted in the previous step 5135 and IQ20 msec, the Regis clutch is turned on via the next step 5143,
After timing adjustment in step 3144, step 5
Proceed to 149. If "No" is determined in step 5141, the process proceeds to step 347, where the time difference is set in a resist clutch on timer (not shown). In this way, if the movement time is shorter than "image position counter time + 1020102O", set the time difference in the timer in RAM 172, count the timer in the interrupt routine described later, and if the timer is If it goes up, at that point I try to turn on the rest clutch.

On the other hand, if it is determined in step 5129 that it is not the first copy, the time (timing) to be measured in steps 5131 to 5141 has already been determined by the first copy. Therefore step 514
In step 5, it is determined whether the moving time of the image is greater than the time counted in step 5135 plus 720 m5ec. This 720 m5ec is the result of subtracting 300 m5ec, the time required for changing the direction of the exposure lamp 28 set after step 5153, from 1020102O in step 5141, and the feeding timing is earlier than the original paper feeding timing (in advance). This is the time during which the registration roller clutch should be turned on.In step 5145, the travel time is calculated as the time counted in step 5135 and 7.
If it is larger than the sum of 20m5ec, proceed to step 5143, and if smaller, proceed to step 5147
Proceed to. Therefore, if the determination in step 5145 is "NO", that is, if the travel time is short, then as in the case of "NO" in the previous step 5141,
It was decided that the subsequent timing would be determined by the interrupt routine.

In step 8149, LED array 46 is turned on so that all LED elements 158 are lit. That is, the microcomputer 168 gives a signal to the LED array 46 to indicate "all lights on." When moving the image to the right, in order to prevent an image on the left side of the document 124, for example, an image of the positioning plate 13, from being formed on the photosensitive drum 38, in other words, to erase an unnecessary electrostatic latent image, L E D ')' t, A46 are all turned on.

After that, in step 5151, the exposure lamp 28 for irradiating light onto the original 124 (emits 1 m of light) is turned on.
The exposure lamp 28 starts up slowly, so 200m5ec
After the time, proceed to the next step 8153 and step 5
At step 153, the first copy is soldered as in step S29. If it is the first copy,
Since the exposure lamp 28 turned on in the previous step 5151 is slow to start up, the process proceeds to step 5155 after a further stabilization time of 300 m5ec has elapsed.

In step 5155, the charging roller 48 is turned on, and the →no-small motor 1f 8 is turned on.

In the next step 5157, it is determined whether the exposure tube 28 has been fed to the image position. If the image position has not been reached in the next step 8159''r゛, the 5 intervals from the home position to the image position are counted.In the case of continuous copying, this slur tab 5159 is used to copy the clicked data. is used as image position data for moving the image to the right.If it is determined in step 5157 that the image position has been reached, the process continues to step 81.
Proceed to 61.

In step 8161, the microcomputer 168 looks at the data in the RAM 172 from the IC card 116 and determines whether the trimming mode is set.

If it is determined in step 5161 that it is not the trimming mode, in the next step 5163, the previous step 5149
The LED array 46 that was turned on is turned off or extinguished.

If it is determined that the mode is trimming mode, step 51
The process proceeds to step 65, while the LED array 46 is kept on, that is, fully lit.

In step 5167, the microcomputer 168 looks at the data in the RAM 172 and determines whether the masking mode is set. If it is determined that the mode is masking mode, the process advances to the next step 5169.

In step 5169, from the IC card 116 to the RAM 17
Points PI, P3.2 for trimming or masking set with transferred false data. The X coordinate positions of P2 and P4 are checked. Specifically, after the start of X coordinate detection is determined in the interrupt routine described above, the detection is performed in the interrupt routine. In step 5171,
The time until the exposure lamp 28 finishes feeding is counted. After that, after a time of 420 m5ec, which corresponds to the normal paper feeding timing, the next step 5 is performed.
Proceed to 173.

In step 5173, as in step 5127, it is determined whether the image moves to the right. If it is f8 movement to the right, since the registration clutch has already been turned on and the registration flora 8o is driven in the previous step 8143, it is determined whether the registration flora 80 is driven and the process proceeds to step 5177.

If it is determined that the image is not to be moved to the right, that is, if the image is to be moved to the left, the time for leftward movement is counted in the next step S1, and then the registration clutch is activated in step 5175.

When it is detected in step 5177 that the exposure lamp 28 has been fed to the return position, the process proceeds to the next step 51791, where the servo motor 178 is turned on and the exposure lamp 28 is turned off. LED array 46 turned on with
is turned off.

In the subsequent step 3181 (FIG. 21B), the microcomputer 168 checks the sheet number counter and determines whether or not continuous copying is being performed. If it is continuous copying, the paper feed sensor is turned off in the next step 5183, and then the process returns to the previous step 5123. That is, for the second and subsequent copies, the process starts from step 5123.

If it is determined in step 8181 that it is not a continuous copy,
Proceeding to step 5185, the servo motor 178 reversed in the previous step 5179 is turned off. Thereafter, the time during which the blank latent image on the photosensitive drum 38 is transferred to the paper 44;
For example, after 200 m5ec, the charging corotron 48 is turned off. The process then proceeds to step 8187, where it is detected that the paper ejection sensor is turned on by the uP paper 44, and the process proceeds to the next step 5189.

In step 8189, the main motor is turned off after 200 seconds, which is the time required to eject the paper 44. The copying machine then goes into standby mode.

Next, another interrupt routine of this embodiment will be explained with reference to FIG. This interrupt routine is called at regular intervals by the internal timer of the microconvenience store 168.

This interrupt routine mainly determines the on timing of the registration clutch in the movement mode, and
Controls the lighting position and timing of the Dat/I 46.

In the first step 5201, the macro computer 16g determines whether the exposure lamp 28 is in the position or not, similar to step 813 in FIG. 18A. If it is not the Baum position, the process directly proceeds to step 5205, but if it is the hoe 11 position, the servo motor 182 is turned off in step 5203, and then the process proceeds to step 5205.

In step 5205, it is determined whether the paper feed sensor is on, that is, whether the paper 44 has been conveyed to the register roller 80. Then, when conveyance of the paper 44 is confirmed, the paper feed clutch is turned off at the next knob 5207. After that, the process advances to step 5211. If the preceding paper is being conveyed, the paper feed sensor has been turned off, so the microphone 1-co-conveyor 168 turns off the registration clutch in the next step 5209, and then proceeds to step 5211.

In step 5211, from the rc card 116 to RAM1
If rightward movement of the image is set by the data transferred to step 72, J'3 goes to step 5147, and it is determined whether the time difference between the movement time and the start timing of the electrostatic latent image has been set in the timer of the RAM. This step 521
If "YES" is determined in step 1, the microcomputer 168 proceeds to step 5213 and determines whether the timer has timed up. Then, when the resist clutch on timer times out after several interrupt routines, in step 5215, the microcomputer 168
Turn on the resist clutch. That is, at this point,
The paper feed timing for moving the image to the right is determined.

In the next step 5217, the microphone computer 168 determines whether the trimming mode or the masking mode has been set and detection of the X coordinate for controlling the ED unit 46 has started. This can be determined, for example, by setting a flag in step S169 (FIG. 18A) and having the microphone computer 168 detect whether the flag is set.

When it is determined to start X coordinate detection, the next step 5219
, the microcomputer 168 determines the area to be trimmed or masked (point P + + P
3 1 P+ (specified by P2 and P4)
One side defined by P* is a partial I-slump, that is, L
It is determined whether the position directly below the ED array 46 has been reached. When the area to be trimmed or masked reaches this LED array 46, the microcomputer 1
68 indicates all LED elements 158 outside the area in the trimming mode 46=- mode.
and, in masking mode, all LED elements 158 within that area.
A signal is provided to D array 46. Thereby, in step 5223, the LED elements 158 of the LED array 46 necessary for trimming or masking are partially and selectively illuminated.

If it is determined "No" in step 5219, the microcomputer 168 performs the following step 522.
1, it is determined whether one side defined by straight lines P4 and P2 of the area to be trimmed or masked has reached directly below the LED array 46. If this is detected in step 5221, the process proceeds to the next step 5225.

In step 5225, the microcomputer 168 determines whether the mode is trimming mode or masking mode. If it is the trimming mode, in step 5227, the LED elements 158 of the LED array 46 are then turned on. Conversely, if the masking mode is selected, the L partially lit in step 5223
The LED elements 158 of the ED array 46 are completely turned off.

After these two steps 5227 or 5229 are executed, the microphone "1 computer 168
At 31, the detection of the X coordinate is completed.

In the subsequent step 5233, the microcomputer 168 determines whether or not the counting of the positions at which the exposure lamp 28 should be allowed to return, which was started in step 5171 described on the left, has started. And step 523
5, the length of the exposure lamp 28 in the moving direction of the document (including the margin) is taken to feed the exposure lamp for the length of time required to feed the exposure lamp 28, and the exposure lamp 28 reaches the position where it should be returned. judge whether If YES' is determined in step 5235, the microcomputer 168 performs the next step 523.
At step 7, the servo motor 182 is turned off, and
In the next step 5239, counting of the feed positions is finished.

In the subsequent step 5241, the microcomputer 168 determines whether the image left movement mode is set based on the data in the RAM 172. If the left movement mode is set, in the next step 5243, the LED array 46 is fully lit in order to erase unnecessary electrostatic latent images for the left movement, and in step 5245, the charging Corotron 4
8 (M3E) to prevent the photosensitive drum 38 from being charged thereafter. After step 5245 is executed, the process returns to the claw-side main routine in FIGS. 21A and 21B, similarly to when "No" was determined in the previous steps 5233 and 5235, respectively.

Thus, according to the above embodiment, in the trimming mode or masking mode, the area corresponding to the two points P+ and P2 set by the position information or data transferred from the IC card 116 to the RAM 172 is LED array (partial erase lamp)
46 lighting areas or ranges are controlled. Furthermore, when the movement mode 12 is set, the microcomputer 168
controls the deviation between the image position and the paper feeding timing according to the amount of movement based on the position data in the RAM 172.

In addition, as shown in FIG. 25, the rc car +! Another IC card 188 may be used instead of 1t6. This IC card 188 has a built-in MPU or CPU and is also called a commercial "microcomputer card."

To explain in detail, this IC card 188 is a microprocessor including a microprocessor 190 (abbreviated as MPU).
controlled by the computer system. In addition to the MPU 190, this micro combinator system includes:
ROM19 for storing control programs etc.
4. A RAM 196 that temporarily stores data during control by the MPU 190 and has an area for various flags necessary for control; 20
The I/O that outputs the control signal shown in Figure), ? An interface 198 is included. In addition, this IC card 188
is normally powered by a power line 202,
As in the previous example, it may be backed up by a lithium battery 200. In addition, the I10 interface 198
is connected to the input/output port 204 of this IC car 1188.

If such a microcomputer card 188 is used, all the control parts except for external circuits such as the liquid crystal display 132 and tablet 126 of the editor main body 122 will be included in the card 18, so the editor main body 122 will include a microcomputer may be omitted. For those of you, please use this method
It would also be possible to have all or part of the microcomputer system in the main body of the copying machine by 88.

Furthermore, as a storage medium, the above-mentioned IC card 1
In addition to 16 or 188, magnetic storage media such as magnetic tape, magnetic disks, etc. may be used. It will be well understood that in this case, a magnetic head or the like is required for writing data to and/or reading data from these magnetic storage media.

FIG. 26 is a perspective view showing another embodiment of the editor used in the present invention. In this embodiment, operation keys 128' are used as input means. That is, a plurality of operation keys 128' are provided on the editor main body 12, and some of the operation keys 128' function as editing function keys, and others function as copy function keys.

Specifically, when performing an editing operation, first a key for a desired editing mode, such as trimming, masking, movement, or centering, is pressed.

When the key for trimming is pressed, the trimming mode is displayed on the liquid crystal display 132. Next, the original 124 is placed face up on the editor main body 122-H, and the coordinate sheet 126' is placed thereon. And the coordinate sheet 12
6', the coordinates of the editing position on the document surface of the document 124 (for example, as shown in FIGS. 11A to 13B) are determined.

To enter coordinates, first press the X1 key. Then, input the data of the coordinate X1 using the digital key. Then, a message indicating that the coordinate data X1 has been accepted is displayed on the liquid crystal display 132. Similarly, coordinate Y1
．． X2 and Y2 can also be entered and set. When the key input is completed, press the memory ink key. Then, the data necessary for editing is stored in the IC card 116 (or 188).

This position data then controls image formation in the main body of the copying machine.

Although FIGS. 26 and 27 only show keys related to the editor as manual keys, it is desirable to provide copying operation keys similar to those in the first embodiment only with functional bones similar to the keys on the main body of the copying machine. , it is preferable that the display (132) is also similar to that of the first embodiment. The second embodiment is based on the pen (1) of the first embodiment.
30) is replaced by a key operation.

Further, in the first embodiment, the editor (122) is provided with operation keys, which are used to input copy information and give instructions on how to display the information, but these operation keys are not attached to the main body of the copying machine. Good too.

(G) Effects of the Invention According to the present invention, the input means and the copying device can be separated, so they can be freely installed in separate spaces. Furthermore, since all the copy mode information can be stored in the storage medium, the input operator and the copy operator can be different people, and input operations to the copy machine do not take much time. In addition, the input operator can obtain the desired copy without error by handing the storage medium and the original to the copy operator and requesting a copy.

Furthermore, since input means can be easily added, a plurality of input operators can perform copy input operations at the same time.

Furthermore, if the input section and the keyboard input section of the copying machine have substantially the same functions, all of the copy information can be input using the input device.

Note that since the selected editing area is displayed by means for displaying it, the operator can confirm the editing area that he or she has selected each time he or she selects the editing area, and will not input incorrect editing area information.
