As shown in FIG. 15(f), the upper left segment lights up, and the encoder count value can be reset to zero. Then, while holding down the key, move parallel to the X-axis direction until you reach the mark after the movement, then turn off the key. At this time, the LED indicated by the broken line in FIG. 15(f') lights up to indicate that the data has been set and completed. The travel distance is set in the microcomputer based on the count value when the key is turned off.

FIG. 15(f') shows a display when area designation for trimming or masking and movement mode are used together.

After confirming that the trimming or masking area specification is complete, if it is trimming, just press the set key 28, but if masking is specified, press MASK.

When all specifications are completed, press the set key 28. Then, the EDIT LED goes out, the C0PY LED lights up, and the display returns to the copy number display.

Next, referring to FIG. 8, the operation of this embodiment will be explained based on the flowcharts shown in FIGS. 16 to 18.

After specifying the position of the original 40 for editing, as shown in FIG. After that, the document cover 18 is closed and the document 40 is fixed on the transparent glass plate 16. Then, press the start key 28 to start the copying operation.

When the start key 28 is fully operated, the 14th r! In the first step Sll of A, the main motor 96 for driving the document table 14, photosensitive drum 46, etc. is turned on. When the rotation of the main motor 96 becomes stable, that is, when 1 sec has elapsed since the main motor 96 was turned on, the solenoid of the cleaning device 88 is turned on and the tip of the blade 90 is brought into contact with the photoreceptor drum 46 . When a predetermined period of time has passed since the solenoid was turned on, 1! For example, if the source is not loaded at the same time, for example 100m5e
When c has elapsed, the process advances to the next step 513.

In step S13, the microcomputer 134
By looking at the signal from the sensor circuit 142 (FIG. 8), it is determined whether the document table 14 is at the home position, that is, whether the right end of the document table 14 is located on the left side of the main body 12. If the loading table 14 is at the home position,
If the process does not proceed to the next step S17, in step 515, a return wrap (not shown) for moving the document table 14 to the home position is turned on, and the document table 14 is moved to the home position.
Turning off this return latch, which returns 4 to the home position, is performed by an interrupt and processing described later.

In step S17, the transfer corotron 72 is turned on. After turning on the transfer Flotron 72, the process proceeds to the next step SL9. In step S19, it is determined whether manual copying is to be performed, that is, whether the recording paper 58 is fed manually rather than from the paper feed cassette 32. If it is a manual copy, proceed to the next step 5.
Proceeding to step 21, the tilt/id of the cleaning device 88, which was turned on in the previous step Sll, is turned off. If it is not a manual copy, the process proceeds to step S23 without passing through step S21.

In the next step S23, the paper feed clutch is first turned on, the paper feed roller 66 starts rotating, and the recording paper 58 is completely conveyed toward the register roller 70. At the same time, the solenoid of the cleaning device 88 is turned off. The solenoid is turned off twice in the case of manual copying in the previous step 519, that is, when the copy goes through step S21, but since only the off signal can be supplied, there is no equivalent change in the solenoid. After 200 m 5 ec has elapsed since the switch was turned off, the process proceeds to the next step S25. This 200 m sec time is the time for determining a jam when the paper feed clutch is turned on and the recording paper 58 is conveyed.

In step S25, it is determined whether or not the document table 14 is at the home position. If it is at the home position, the process advances to the next step S27.

In step S27, the microcomputer 134
It is determined whether the mouse 36 has been designated to move the image to the right using movement mode 1:. That is, the mouse 36
After the edit key 124 (FIG. 7) is operated, the movement key 128 . It is determined whether the image is set to move to the right using the X key 130 and the Y key 132.0 If the image is set to move to the right, the process advances to step S29 and the image is moved to the right. If the settings have not been completed, the process advances to step S51.

In step S29, it is possible to determine whether it is the first copy or not. If it is the first copy, the process advances to step S31; if it is not the first copy, that is, if it is the second or later copy, the process advances to step S45.

In step 531, after 300 m5ec has elapsed, the document table 1
In step S33 of the 0th order, in which a feed clutch (not shown) for scanning the document 4 is turned on, it is determined whether the document table 14 is located at the image position. The image position, that is, the position of the document table at which the image of the document 40 starts to be formed as an electrostatic latent image on the photoreceptor drum 46 is determined. If it is not the image position, in the next step 835 the time from the home position to the image position is counted by a counter. Once the image position is reached, proceed to the next step S37.
In step S37, the feed clutch is turned off, and 200 msec later, the return clutch of the document table 14 is turned on.

In this way, when the right movement is set and the first copy is being made, the time from the home position to the image position is unknown for the first copy, so the document table 14 must be moved before starting copying. You need to measure that time.

Next, in step S39, it is determined whether the document table 14 has returned to the home position. If it returns to the home position, the process proceeds to the next step S41, and step 94
1, step S in which the time to move the image to the right is first
It is determined whether the time is greater than the time counted at 35 plus 1020 msec. This 1020
m sec is set at step S51, which will be described later.
00 m sec, 300 m s after step 353
ec is the sum of 100 m5eC that can be set in step S55 and 420 m5ec that can be set in step 571. That is, in order to move the image to the right, it is necessary to advance the feeding of the second recording paper before the formation of the latent image, but the time allowed for this advance is the original start time of paper feeding, that is, the timing of resist clutch on in step S75. Determine whether the time is longer than the

If the image movement time is greater than the sum of the value counted in the previous step S35 and 1020 m sec, the registration clutch is turned on in the next step 843, and the timing is adjusted in step S44, and then the process proceeds to step 349. If it is determined ``No'' in step S41, the process advances to step S47, and the time difference is set in a resist clutch on timer (TyJ not shown). In this way, the moving time is the image position counter time + 10
If it is shorter than 20m sec, the time difference is stored in RAM.
This timer is set in the internal timer, and counted by the interrupt routine described later. If the timer counts up, the resist clutch is turned on at that point.

On the other hand, if it is determined in step S29 that it is not the first copy, the time (timing) to be determined in steps 331 to 341 has already been determined by the first copy. Therefore, in step S45, it is determined whether the moving time of the image is greater than the time counted in step 835 plus 720 m5ec. This 720m5ec is 10 in step S41.
The time required for changing the direction of the document table 14 set after step 853 is 300 m5 sec from 20 m sec.
This is the time when the registration clutch should be turned on earlier (in advance) than the original paper feeding timing. In step S45, if the travel time is greater than the sum of the time counted in step S35 and 720 m sec, the process proceeds to step 543, and if it is smaller, the process proceeds to step S47. Therefore, step S
If the answer is "1 NO" in step 345, that is, if the travel time is short, the subsequent timing is determined by the interrupt routine, as in the case of "no" in step 341.

In step S49, the LED array 48 is turned on so that all the LED elements 5o are lit. That is, the microcomputer 134 provides a signal for "all lighting" to the LED array 48.

When moving the image to the right, in order to prevent an image on the left side of the document 4o, for example, an image of the positioning plate 20, from being formed on the photoreceptor drum 46, that is, to erase an unnecessary electrostatic latent image, This causes the LED array 48 to be fully lit.

After that, in step S51, the light source 42 for irradiating (exposing) the document 4o with light is turned on, and since the light source 42 starts up slowly, the process proceeds to the next step 853 after a time of 200 m5ec. As in step 329, it is determined whether this is the first copy. If it is the first copy, the light source 42 turned on in the previous step S51 starts up slowly, so it will take an additional 300 m se
After the stabilization time c has elapsed, the process advances to step S55.

In step S55, the charging floaton 48 is turned on and the feed clutch is turned on.

In the next step S57, it is determined whether the document table 14 has been fed to the image position. If the image position has not been reached, proceed to the next step S.
59, the time from the home position to the image position is counted.

During continuous copying, the data counted in step S59 is used as image position data for moving the image to the right. If it is determined in step S57 that the image position has been reached, the process proceeds to the next step S61.

If it is determined in step S61 that it is not the trimming mode, in the next step S63, the LED array 48 that was turned on in the previous step S49 is turned off or extinguished. If it is determined that the mode is trimming mode, the process proceeds to step 365, while the LED array 48 is kept on, that is, fully lit.

In step S67, the microcomputer 134
The old issue from the mouse 36 is looked at to determine whether the masking mode is set. If it is determined that the mode is masking mode, the process advances to the next step 809.

In step S69, the point P for trimming or masking set with the mouse 36! and the position of the X coordinate of P2 is checked. Specifically, after the start of X coordinate detection is determined in an interrupt routine to be described later, the detection is performed in the interrupt routine. Then, in step S71, the time until the document table 14 finishes feeding is set on a counter. Thereafter, after a period of 420 msec has elapsed, which corresponds to tacking and bubbling in the normal case, the process proceeds to the next step S73.

In step S73, as in step 327, it is determined whether the image moves to the right. If the movement is to the right, since the registration claps have already been turned on and the registration rollers 70 have been driven in the previous step S43, it is determined whether the registration rollers 70 are driven and the process proceeds to step S77.

If it is determined that the image is not to be moved to the right, and if the long straw image is to be moved to the left, the time for leftward movement is counted in the next step S74, and then the registration clutch is turned on in step S75.

In step S77, when it is detected that the document table 14 has been completely fed to the return position, the next step 3
Proceeding to step 79, the return clutch is turned on, and
The exposure light source 42 is turned off, and the LED array 48 that was turned on in the previous step 349 is turned off.

In the subsequent step 581 (FIG. 16C), the microcomputer 134 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 183, and then the previous step S2
Return to 3. That is, for the second and subsequent copies, the process can start from step 323.

If it is determined that it is not a continuous copy by the stainless knob S81,
The process advances to step S85, and the return clutch is turned on or turned off in step S79. After that, the charging corotron 72 is turned off after the electrostatic latent image on the photosensitive drum 46 is transferred to the recording paper 58, for example, 200 m5ec. Then, proceed to step 387, and step 38
In step S89, it is detected that the paper ejection sensor is turned on due to the ejection of the second recording paper 58, and the process proceeds to the next step 889. Turn off motor 96. The copying machine then goes into standby mode.

Next, the interrupt routine of this embodiment will be explained with reference to FIG. This interrupt routine is called at regular intervals by an internal timer of the microcomputer 134. In this interrupt routine,
It mainly determines the on timing of the registration clutch in the movement mode, and controls the lighting position and timing of the LED array 48 in the trimming or masking mode.

In the first step 3101, the microcomputer 134 determines whether the document table 14 is at the home position, similar to step 813 in FIG. 14A. If it is not at the home position, the process directly proceeds to step 5105, but if it is at the home position, the return clutch is turned off in step 5103, and then the process proceeds to step 5105.

In step S105, it is determined whether or not the paper feed sensor is on, that is, whether or not the recording paper 5 reaches the register roller 70.
It is determined whether or not 8 has been completely transported. Then, when conveyance of the recording paper 58 is confirmed, the paper feed clutch is turned off in the next step 5107. Then step 51
Proceed to step 11. If the preceding recording paper has been conveyed,
Since the paper feed sensor is turned off, the microcomputer 134 turns off the registration clutch in the next step 5109, and then proceeds to step 5111.

In step 5111, when rightward movement of the image is set using the mouse 36, it is determined in the steno knob S47 whether the time difference between the movement time and the start timing of the silent image is set in the timer of the RAM. This step 5
If it is determined as 'YES' in 'ill', the micro convenience store 134 in the following step S113,
Determine whether the on-timer has timed up. Then, after going through several interrupt routines, when the resist clutch on timer times out, in step 5115, the microcomputer 134
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 5117, the microsimulator 134 determines whether the trimming mode or the masking mode has been set and the detection of the X coordinate for controlling the LED array 48 has started. This can be determined by, for example, setting a flag in step S69 (FIG. 16B) and having the microcomputer 134 detect whether the flag is set.

When the start of X coordinate detection is determined, the next step 5119
At , the microcomputer 134 determines whether the left corner of the area to be trimmed or masked has reached directly below the partial erase lamp or LED array 48 . Then, when the area to be trimmed or masked reaches this LED array 48, the micro combinator 134 lights up all LED elements 50 outside the area in trimming mode and in masking mode. A signal is given to the LED array 48 so as to light up the ED element 50 in the screen. Thereby, in step 5123, the LED elements 50 of the LED array 48 necessary for trimming or masking are selectively illuminated.

If it is determined “NO” in step 5119,
The microcomputer 134 reads step 5121
At , it is determined whether the left corner of the area to be trimmed or masked has reached directly below the LED array 48. When this is detected in step S121, the process proceeds to the next step S121.
Proceed to step 25.

In step 5125, the microcomputer 134 determines whether the mode is trimming mode or masking mode. If it is the trimming mode, all LED elements 50 of the LED array 48 are then turned on in step 5127. On the other hand, in masking mode,
In step S123, all of the LED elements 50 of the LED array 48 that were partially lit are turned off.

After these two steps 8127 and 5129 are executed, the microcomputer 134 completes the detection of the X coordinate in step 5131.

In the subsequent step 5133, the microcomputer 134 determines whether or not the counting of the positions to which the document table 14 should be returned, which was started in the previous step S71, has started. Then, in step 5135, the length of the document in the moving direction of the document table, including the margin, is determined.
The time required to feed the document table 14 is counted, and it is determined whether the document table 14 has reached the position where it should be returned. If it is determined as 'YES' in this step 5135, the microcomputer 1
34 turns off the feed clutch in the next step 5137, and finishes counting the feed position in the next step 5139.

In subsequent step 5141, if the image left movement mode is set based on the signal from the mouse 36, the microphone computer 134 performs the next step 514.
43, in order to erase unnecessary electrostatic latent images due to the leftward movement, the LED array 48 is fully lit, and in step 5145, the charging corotron 47 (
(FIG. 2) is turned off to prevent the photosensitive drum 46 from being charged thereafter. After step 5145 is executed, the previous step 5133 and step 5135
In the same way as when it was determined 'No' in each case,
The process returns to the main routine shown in Figures 16A-160S.

Thus, according to the above-described embodiment, in the trimming mode or the masking mode, the LED array 1' (partial erase lamp) 48
Controls the lighting area or range. Further, when the movement mode is completely set, the microcomputer 134 controls the deviation between the image position and the paper feeding position and the f-timing according to the movement amount based on the position data inputted from the mouse 36.
