The rubber roller 116 rolls over the original 40 during editing, and applies rotation to the slit disk 110 in accordance with the distance traveled. On the right side of the above-mentioned rotary encoder 106, a rubber roller 116 is installed.
Similarly, an auxiliary roller 118 that is rotated with a part of its circumferential side protruding below the case 100 is provided. The auxiliary roller 118 cooperates with the rubber roller 116 to regulate the direction of movement of the mouse 36 so that it can move straight on the document 40 during editing.

The distance the mouse 36 is moved over the document 40 is converted into a rotation of the slit disk 110 by the rubber roller 116 . The slit disk 110 changes the light emitting element 1 according to its rotation.
In order to block the 12 lights at regular intervals, the light receiving element 114 outputs a voltage signal with a frequency corresponding to its rotation speed.

The voltage signal from this light receiving element 114 is sent to the voltage comparator 120.
The signal is shaped into a pulse, and is applied to the control section 98 of the main body 12 via the connector 122 and the telescopic hood 38.

In addition, the output boat of the micro combi coater 134 has
A partial erase lamp or LED array 48 is read directly to erase electrostatic latent images that are no longer needed due to editing. The operation of this LED array 48 has been described above.

Next, prior to explaining the operation, each of the trimming mode, masking mode, and movement mode will be briefly explained with reference to FIGS. 9A to 11B.

In the trimming mode, two points P1 (X t + Y t ) and P2 (
Only the portion of the image corresponding to the rectangular area 148 connecting the points Xz, Yl) is left, and the rest of the image is erased as shown in FIG. 9B. Therefore, in this mode, the plurality of LED elements so, so, . . . included in the LED array 48 are lit only outside this region 148.

In masking mode, two designated points P 1 (X 1 # Y L ) and P2 (
Only the portion of the image corresponding to the rectangular area 150 connecting X21Y2) is erased, and the remaining portion of the image is left intact as shown in FIG. A plurality of LED elements 50
．． 50 . . . can be turned on only within this area 150.

In the movement mode, as shown in FIG. 11A, the coordinates P s (X s *Y
l), and then specify the coordinates P3 (Xl, Yl) of the point to be moved while keeping the Y coordinate 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. 11B is formed. That is, in this mode, the LED array 48 is not used, and the timing of paper feeding and document table drive is controlled by coordinate data, as will be described later.

Before starting a copying operation, the operator places the original 40 on a flat surface such as the original table 14 or the original cover 18 so that the original surface faces upward. Thereafter, as shown in FIG. 12, the mouse 36 is manually lifted and placed so that the hole 102 is aligned with the edge of the document 40, and the mouse 36 is used to, for example, trim or mask an area (encircled by a dashed line). The coordinates Pl(

Next, with reference to FIG. 8, the operation or operation of this embodiment will be explained based on the flowcharts shown in FIGS. 14 to 16.

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

When the start key 28 is operated, in the first step Sll in FIG.
The main motor 96 for driving etc. is turned on.

When the rotation of the main motor 96 becomes stable, that is, when 1 sec has passed since the main motor 96 was turned on, the cleaning device! ! The solenoid 88 is turned on and the tip of the wire 90 comes into contact with the photosensitive drum 46. When a predetermined period of time has elapsed since the solenoid was turned on, that is, when, for example, 100 m5ec has elapsed so that no load is applied to the power supply at the same time, the process proceeds to the next step S13.

In step 513, 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 document table 14 is at the home position,
If the process does not proceed to the next step 317, in step S15, a return latch (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.
4 to the home position, this return latch is turned off by interrupt processing, which will be described later.

In step 517, the transfer corotron 72 is turned on. After turning on the transfer flotron 72, the process proceeds to the next step 519. In step 519, it is determined whether or not manual copying is being performed, that is, whether the recording paper 58 is fed manually rather than from the paper feed force hitter 32. If it is a manual copy, proceed to the next step 3.
21, the solenoid of the cleaning device f88 that was turned on in step 911 is turned off. If it is not a manual copy, the process proceeds to step 323 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 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 919, that is, in the case of passing through step S21, but since only the off signal can be supplied, there is no equivalent change in the solenoid. After 200 m5 ec has elapsed from the time of turning 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 5B is conveyed.

In step 325, it is determined whether the document table 14 is at the home position, and 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 in the movement mode. Sunawa Mouse 36
After the edit keys 124 (FIG. 7) have been fully operated, move keys 128 . It is determined whether the X key 130 and Y key 132 are set to move the image to the right. If the image has been set to move to the right, the process proceeds to step S29, and if the image has not been set to move to the right, the process proceeds to step S51.

In step 329, it is determined whether this is the first copy. 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 S31, after 300 m5ec has elapsed, the original platen 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, the time from the home position to the image position is counted up by the counter in the next step 535. 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 hono position. If it returns to the home position, proceed to the next step 541, and step S
At step 41, it is determined whether the time to move the image to the right is greater than the time counted at step 535 plus 1020 ms:c. This 102
0m sec is 200m5ec set in step SSI described later, 300msec after step S53
ec is the sum of 100 m5ec set in step S55 and 420 m5ec set in step 371. That is, in order to move the image to the right, it is necessary to advance the feeding of the recording paper before the formation of the latent image, but this advance time does not last until the original paper feeding start time, that is, the timing of resist clutch on in step 375. Determine if it is longer than the time.

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 through the next step S43, and the timing is adjusted in step S44, and then the process advances to step S49. If it is determined 'NO' in S41, the process proceeds to step S47, and the time difference is set in a registration/clap-on timer (not shown).In this way,
Travel time is image position counter time + 102
If it is shorter than 0 m sec, the time difference is stored in the timer 7 in the RAM, and the timer is counted in the interrupt routine described later. If the timer counts up, the resist clutch is turned on at that point. I have to.

On the other hand, if it is determined in step 829 that it is not the first copy, the time (timing) to be measured in steps 931 to 341 has already been determined by the first copy. Therefore, in step 345, it is determined whether the moving time of the image is greater than the sum of the time counted in step S35 and 720 m5ec. This 720m5ec is 10 in step S41.
The time required for changing the direction of the document table 14, which can be set after step S53, ranges from 20 m sec to 300 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, the travel time is determined in step S35.
If it is greater than the time counted in + 720m sec plus an an hour, the process proceeds to step S43; if it is smaller, the process proceeds to step S47. Therefore, if it is determined "NO" in step 545, that is, the travel time If the time is short, the subsequent timing will be determined by the interrupt routine, as in the case of "NO" in step S41.

In step S49, the LED array 48 is turned on so that all the LED elements 50 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 40, such as the image of the positioning plate 20, from being formed on the photoreceptor drum 46, that is, to erase an unnecessary electrostatic latent image, This will turn on all LED lights 48.

Thereafter, in step S51, the light source 42 for irradiating (exposing) the document 40 with light is turned on, and since the light source 42 starts up slowly, the process proceeds to the next step S53 after a time of 200 msec. As in the previous step S29, 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 is slow to start up, so an additional 300 m5 is required.
After the ec stabilization time has elapsed, the process proceeds to step 555.

In step S55, the charging flotron 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 S5.
At step 9, the time from the home position to the image position is counted.

During continuous copying, the data counted in step 859 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.In step S61, the microcombi coater 134 checks the signal from the mouse 36 and determines whether the trimming mode is set. do. When in the trimming mode, the trimming/masking key 126 of the mouse 36 is not fully operated and L E D 1
Since 26a is lit, microcomputer 13
4 can be determined by checking the state. If it is determined in step 861 that it is not the trimming mode, in the next step S63, the L that was turned on in the previous step 549
The ED array 48 is turned off or extinguished. If it is determined that the trimming mode is in effect, the process proceeds to step 565, while the LED array 48 remains on, that is, fully lit.

In step 367, the microcomputer 134c,
The signal from the mouse 36 is checked to determine whether the masking mode is set. If in masking mode, press trimming/masking key 1 on mouse 36.
26 has been fully operated and the LED 126b is lit, it is only necessary to judge whether the micrometer computer 134 is in that state. If it is determined that the masking mode is established, the process proceeds to the next step S69.

In step S69, the X coordinate positions of the trimming or masking points P1 and P2 set with the mouse 36 are 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 in a counter. Thereafter, after a period of 420 msec, which corresponds to the normal paper feeding timing, has elapsed, the process advances to the next step S73.

In step S73, it is determined whether the image is moved to the right as in step S27. If the movement is to the right, the registration clutch has already been turned on to drive the registration rollers 70 in the previous step S43, so 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, that is, if the 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 S77 is performed.
79, the return clutch is turned on,
The exposure light source 42 is turned off, and the LED array 48 that was turned on in the previous step 549 is turned off.

In the subsequent step 581 (FIG. 14C), the microcomputer 134 checks the sheet number counter and determines whether or not continuous copying is being performed. Fortunately, if it is 4tI near-pi, the paper feed sensor is turned off in the next step 883, and then the process returns to the previous step S23. In other words, for the second and subsequent copies, the process can also be started at step 323.

If it is determined in step S81 that it is not continuous copying, the process advances to step 885, and in step S79, the return clutch is turned on or turned off. After that, the photoreceptor drum 4
After the electrostatic latent image on the recording paper 58 is completely transferred to the recording paper 58, for example, 200 m5ec, the charging layer corotron 72 is turned off. Then, the process advances to step S87, and step S87
Then, it is detected that the paper ejection sensor is turned on due to the ejection of the recording paper 58, and the process proceeds to the next step 989. In step S89, after the time 200 m5ec required to eject the recording paper 58, the main motor Turn off.

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 a certain interval 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 5101, the microcomputer 134 determines whether the document table 14 is at the home position, similar to step S13 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 recone clutch is turned off in step 5103, and then the process proceeds to step 5105.

In step 5105, it is determined whether or not the paper feed sensor is on, that is, if the recording paper 58 reaches the register roller 70.
Determine whether the has been transported. And recording paper 5
When the conveyance of paper No. 8 is confirmed, the paper feed clutch is turned off in the next step 5107. Then step 511
If the preceding recording paper is being conveyed, the paper feed sensor is turned off, so the microcomputer 134 turns off the registration clutch in the next step 5109, and then advances to step 5111.

In step S111, if rightward movement of the image is set using the mouse 36, it is determined in step S47 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. If it is determined as “YES” in step 5111, the microcomputer 134 will proceed to step 5113.
Determine whether the on-timer has timed up. When the registration clutch noteon timer times out after several interrupt routines, the microcomputer 134 turns on the registration clutch in step 5115. That is, at this point, the paper feeding timing for moving the image to the right is determined.

In the next step 3117, the microcomputer 134 determines whether the trimming mode or masking mode has been set and detection of the X coordinate for controlling the LED array 48 has started. This can be determined, for example, by setting a flag in step 569 (FIG. 14A) and having microcomputer 134 detect whether the flag is set.

When the start of X coordinate detection is determined, the next step 5119
, the microcomputer 134 determines that the left corner of the area to be trimmed or masked (which can be specified by points P1 and P2) is a partial erase ramp, that is, L.
It is determined whether the position directly below the ED array 48 has been reached. When the area to be trimmed or masked reaches this LED array 48, the microcomputer 1
34 signals the LED array 48 to illuminate all LED elements 50 outside the region in trimming mode and to illuminate all LED elements 50 within the region in masking mode. give. Thereby, in step 5123, the LED elements 50 of the LED array 48 necessary for trimming or masking are selectively illuminated.

If “NO” is determined in step 5119,
The microcomputer 134 performs the following step 5121
At , it is determined whether the left corner of the area to be trimmed or skimmed has reached directly below the LED array 48. If this is detected in step 5121, the process moves to the next step 51.
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,
LE that was partially lit in step 5123
All the LED elements 50 of the D array 48 are turned off. After these two steps 5127 or step S129 are completed, the micro combinator 134 completes the detection of the X coordinate in step S131.

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 3135, the length of the document in the direction of movement of the document table (including the margin)
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. Then, in this step 5135, if it is determined as “YES”, the micro combinator 1
34 turns off the feed clutch in the next step 5137, and finishes counting the feed position in the next step 5139.

In the subsequent step 5141, the microcomputer 134 determines that the image left movement mode is set based on No.
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 (
The second @) is turned off to prevent the photosensitive drum 46 from being charged thereafter. After step S145 is completed, the previous steps 5133 and 513
Similarly to when the determination in step 5 is "NO", the process returns to the main routine shown in FIGS. 14A to 14CI5A.

Thus, according to the above embodiment, in the trimming mode or the masking mode, the LED array (partial erase lamp) 48 corresponds to the area defined by the two points P1 and P2 set by the 79 screen 36. Controls the lighting area or range. Further, when the movement mode is set, the microcomputer 134 controls the mouse 3
Based on the position data input from 6, the deviation between the image position and the paper feeding timing is controlled according to the amount of movement.
